Description

technical field [0001] The invention relates to a cooling fan, in particular to a cooling fan with double evaporation and electronic refrigeration. Background technique [0002] The existing cooling fans on the market basically use the principle of water evaporation and heat absorption to make the air pass through the humidification filter material, so as to achieve the purpose of cooling and humidifying the air. It is small in size, movable, cheap, energy-saving and environmentally friendly, and has a broad market prospect. However, due to the limitation of the principle of water evaporation and heat absorption, the effect of cooling and cooling is not ideal. [0003] In order to improve the cooling effect, some cooling fans are equipped with ice crystal boxes, which are frozen and put into the cooling fan water tank for use. However, the shell of the ice crystal box is mostly plastic, which has poor thermal conductivity, and the contact area between the ice crystal box an...

Problems solved by technology

[0005] However, due to the large amount of circulating water in this scheme, and the poor insulation effect of the water tank and the water inlet and outlet pipes, the cooling capacity of the cold water in the water tank and the water inlet and outlet pipes will lose a lot, so the temperature of the circulating water cannot drop much

According to the principle of evaporative refrigeration, the cooling effect of evaporative cooling is determined by the evaporation of circulating water, and the cooling effect of evaporative cooling is not significantly improved by a small decrease in circulating water temperature. It is difficult to achieve the ideal cooling and cooling effect only by relying on a single cooling of evaporative cooling

[0006] In addition, the evaporative refrigeration device in this scheme still adopts the method of rolling curtains, the evaporation efficiency of the circulating water on it and the heat exchange efficiency with the air are low, and the cooling and cooling effect is not obvious

[0007] In addition, the electronic refrigeration device also generates a certain amount of heat while cooling. In the above-mentioned patent, the waste heat generated by the electronic refrigeration device is directly discharged into the room through the cooling fan, which will cause the room temperature to rise, which will also affect its cooling.
