Description

Ventilation radiator fan guide structure

This creation department relates to a roof ventilation radiator, especially a ventilation guide structure of a ventilation radiator that can increase ventilation and facilitate maintenance.

According to the regulations, many factories are in the form of iron houses. Because the roof of the wave plate will be easily exposed to the sun and absorb heat, it often causes indoor sweltering, and the iron house is set as a pointed roof. The general window exhaust will be difficult to discharge and hoard. The hot air on the roof prevents the air in the room from being effectively circulated, and the sweltering feeling in the house cannot be eliminated. Therefore, the factory will install a heat sink on the roof of the wave board, and the hot air will be discharged from the roof through the heat sink. In order to achieve the purpose of preventing rainwater from being poured into the house, the heat-dissipating cover is provided with a slanted rain shield in the heat-dissipating cover, so that the rainwater can discharge the heat-dissipating cover along the flashing, but the above-mentioned It is not difficult to find out that there are still some shortcomings in the structure. The main reason is as follows: The natural exhaust heat dissipation method is to ventilate and dissipate heat through the hot gas updraft, so it is necessary to raise the temperature of the room before effective heat dissipation. As a result, the indoor temperature can only drop to a temperature that is still too high, and the ideal heat dissipation effect cannot be effectively achieved. Therefore, some of the heat dissipation covers will be equipped with an exhaust fan and driven by electric power. The exhaust fan achieves the purpose of pumping out hot air, and the exhaust fan is usually a type of rotating shaft blade, so that when the rotating shaft blade drives the hot air to exhaust, a part of the airflow is also pushed toward the opposite direction of the exhaust, which causes the driving of the exhaust fan. The increase in resistance will not only reduce the flow rate of the exhaust gas, but also increase the power consumption. In addition, if the exhaust fan in the heat shield fails, the exhaust fan will be difficult to repair and replace, and the exhaust fan is also the same. Not allowed Easy to clean, the above-mentioned shortcomings are the problems that the creative office wants to improve.
