1. Water cooled or forced fan
2. Corruption among the cadres has become a common practice, and the accounts of the enterprises are in chaos. It seems that they have to go on the market to earn money. It's not approved. It's killing people. The workers go on strike every day, and the chairman is dismissed all his life. Now there is no one working in the factory, the quality of the procts is falling rapidly, and it's going to close down. The heavy machinery and the state are not in charge, and the people can't live

the working principle of gas-fired infrared radiation heating is: burning natural gas, liquefied natural gas or liquefied petroleum gas (artificial gas can also be used, but the calorific value is low, the amount of harmful substances in combustion procts is more, and the application is less), heating radiation metal tube, plate or ceramic plate, It can proce direct thermal radiation (also known as primary radiation) and secondary radiation and convective heat transfer on the inner surface of enclosure structure and equipment of heating room, so as to create comfortable microclimate conditions for heating area. It can also be used for proction process heating, but it is mainly used for heating, so it is hereinafter referred to as gas radiator heating. Composition of gas radiator: gas burner, radiant tube or plate, reflector, regulation, control and security components
1 gas radiator heating has the advantages of high efficiency and energy saving
if traditional radiators (radiators) are used as heat release equipment in tall buildings, it is difficult to arrange large-span rooms. In some workshops, the wall is full of radiators, and the heating mode mainly relies on natural convection heat release, resulting in large temperature gradient up and down, up to 0.5 ~ 1.0 ℃ / m, which makes the air temperature under the roof as high as 32 ℃. However, the air temperature distribution in the working area where people stay less than 2m is uneven, and in some places it is only 3 ~ 5 ℃. Heating system is not for building and indoor air service, but should be people-oriented, in addition to meeting the requirements of proction technology, to personnel comfort and rece energy consumption as the main goal. If the heating mode of radiator plus heater or centralized air treatment is used, it will not only occupy the building area, but also cause st lifting, affecting health and human health. In some cases, it is prohibited. As for the heating of open and semi open sites, the use of gas radiator has incomparable advantages
the average temperature in the metal tube of gas radiator is 180 ℃～ 550 ℃, procing 3.5 ℃ μ～ ５．５ μ The infrared ray of wavelength passes through the air layer and is absorbed by human body and objects, with remarkable thermal effect. The ground temperature is 4 ℃～ 8 ℃ higher than the ambient air temperature. The ground, wall, object temperature and secondary radiation can make the air temperature distribution in the working area less than 2m even and create a comfortable microclimate. The working area temperature of radiator heating room can be 2 ℃～ 3 ℃ lower than that of convection heating mode, which can meet the same comfort. The temperature gradient of the upper and lower parts of the house is small, the upper air temperature is not high, and the invalid heat loss is reced
when steam or hot water boilers are used for heating, small boilers shall be set η= 70%, the heat loss of heat medium transportation in external network is 5%, and the heat loss of internal network and equipment is 10%
the total efficiency η＝ zero point seven × zero point nine five × 9 ≈ 60%, and gas radiator heating η Up to 90%. Compared with the traditional way, the gas radiator can save 33% ～ 50% energy in one heating period. In addition, it has the following advantages: low air velocity in the room, less st and other harmful substances flying, no noise when working, no freezing, short installation period and so on<
2 the application scope of gas radiator heating
gas radiator can be used for:
1) the working area or working point of the proction workshop (especially when it is applied to the large and open workshop with scattered working points)
2) working area and working point of open-air workplace (with incomparable advantages of other heating methods)
3) civil buildings and open sites where people stay for a short time. For example: station platforms, bus waiting rooms, sports venues, exhibition halls, open or semi open markets, etc
4) heating of buildings and structures in the process of construction
5) process heating for materials and equipment
6) snow melting in open field and semi open field, and roof melting of houses and structures< As pointed out in the article description of code for design of heating, ventilation and air conditioning in China, "at present, there are many new types of gas-fired heating equipment in many developed countries, which have the characteristics of high efficiency, energy saving, comfort and sanitation, and low operation cost. The heating method is especially suitable for buildings with large space. With the development of China's petroleum instry and the development and utilization of oil and gas fields, the application of this heating method is increasing
there are hundreds of projects using gas radiator heating in Russia, including the comprehensive workshop of machinery manufacturing plant in Qiuming oilfield, the largest locomotive maintenance equipment warehouse in Europe located in Moscow Kiev station (see photo 1), aircraft maintenance workshop of international and domestic main routes in fenukovo, etc. Shanghai topbang Electronics Co., Ltd., the exclusive agent of gaz instry de France in China, has used the gas radiator in Tianjin Tropical Botanical Garden, the largest tropical botanical garden in Asia. The botanical garden is located in Xiqing District of Tianjin city, with a building area of 40000 m2 and a height of 10-16m. The total investment is 260 million yuan. It has been completed and equipped with intelligent ventilation, water supply and ventilation Automatic shading and cooling equipment, together with gas radiator, create indoor ecological environment similar to the original environment of tropical plants (see photo 2).

5. When we get to the house, we don't feel cold. Every day before dawn, our parents get up. One warms my brother and I in the quilt, and the other is busy making a fire. Sometimes when it's too late to go to school, we put our cotton padded jacket and trousers on the fire to heat up. We put on our hot clothes and set out on the road. When I came back from school, I went to the Kang as soon as I entered the room, warming my legs and feet while warming my hands on the brazier. In winter, the windy classroom often makes my hands and feet frozen and swollen. Sometimes I can't hold my pen. I have to skate, snowball fight, squeeze meat, fight birds and collect firewood outside after school and in winter vacation. As a result, my hands and feet are swollen and my clothes are often worn out. I don't know how much I have worried my parents, so that I can't itch my feet in a house with a stove after I work
of course, fire and poisoning are still fresh in people's memory. Dry firewood is not fire-resistant in the brazier, and coal blocks are usually used to surround the brazier. Then dry firewood or hemp sticks are used to make a fire, and large charcoal is put on it. This is both economical and rable. Some people think that the firepower of coal bricks is small, so they use special large charcoal. A hill is built in the brazier, and the flames come out. After the fire is strong, it is especially warm, But if there is no one at home, sometimes the hill will collapse, burning bamboo mats and quilts, sometimes the soot is too big, it will be poisoned. My family has burned it several times, mostly ring the day when there is no one at home. Charcoal fire falls on the Kang and ignites bamboo mats and quilts. Sometimes it is also when we play with fire. No matter what, it's very dangerous, so in winter, our parents strictly ask us not to take matches with us, fold quilts in time when we get off the Kang, and put them in an open place when we go to bed at night, so as to avoid poisoning
the winter brazier always accompanied me through my school days until I joined the work. Although there was a stove in my unit, I often went to the countryside to squat in the maxia mountain area. The farmers there used braziers like my family. The difference was that most of the fuel was excellent firewood. Because of the large temperature difference between day and night in Guanshan, "I wore cotton padded jacket in the morning, wore yarn in the afternoon, and ate watermelon with brazier in the evening.", They can't do without a brazier all the year round. The brazier is not only used for heating, but also for boiling cans of tea and baking steamed buns. When I go to the countryside, I often live in the farmer's home, looking at the simple villagers and the warm brazier, just like living in my own home, which adds courage and strength to my lonely, lonely and young life. Later, I was transferred to the city, and the unit used the heating, but my parents still used the brazier. When I got married, I spent 25 yuan in Ankou mining machinery factory to buy a stove. After the wedding in my hometown, I left the stove to my parents and younger brother. When my younger brother got married, I spent 70 yuan on a pig iron stove in Shenyu street. In the past, it was my parents who gave us warmth, but now they are old. Although I can't be filial at my knees, I can't let my elderly parents get cold in the cold winter. So I buy Charcoal early every year and send it back to my hometown. However, they always say, "the stove costs too much charcoal, and the brazier is good." I can't bear to add charcoal, so the stove doesn't burn well, and the home is still very cold. But whenever I go home to visit them, they always add charcoal to the stove for fear of freezing me.

There are both blowing type and suction type
according to the specific situation, the key is to form an air ct, ensure that the air blowing to the target is the cold air absorbed from the outside, and ensure that the hot air absorbed is discharged from the outside of the equipment without being sucked in again by the radiator
no matter the engine or electronic components, the principle is the same. They can blow and absorb air. The key is to see whether the air ct design is reasonable. Generally speaking, it means where the cold air comes in and where the hot air goes out
extended information
precautions for purchasing CPU heat sink
1. Use with the host
generally, the larger the heat sink of the cooling fan, the better the heat dissipation effect, but the position of the fan in the host and the size of the space in the chassis must be considered. We should also pay attention to whether the host can accommodate the height after installing the fan, whether the expansion slot will be blocked by the fan or heat sink when installing the interface card, and whether the heat sink fan can fasten the cpij fan slot
2, quality
cooling fans are also divided into box and bulk. Usually, boxed cooling fans are marked with many relevant technical specifications on their packaging, such as fan speed (unit: R / min), power, etc. In short, easy installation and good heat dissipation effect are the most important considerations when choosing CPU fans. If you plan to overclock, you can buy brand-name procts with better performance
