Description

Evaporative and electronic dual refrigeration cooling fan

technical field

The utility model relates to a cooling fan, in particular to an evaporation and electronic double refrigeration cooling fan.

Background technique

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.

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 and water is limited. , so the water temperature in the water tank cannot be dropped a lot, so the use of ice crystal boxes does not significantly improve the cooling effect of the cooling fan.

In the prior art, there has been a scheme of introducing an electronic refrigeration device into a cooling fan to enhance its cooling and cooling effect. For example, patent CN2533410Y discloses an electronic refrigeration water-cooled air-conditioning fan, which uses an electronic ice bladder to first cool the circulating water. Then, the refrigerated circulating water is sprayed onto the rolling curtain to increase the cooling effect of the cooling fan.

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 loss of the cold water in the water tank and the water inlet and outlet pipes is very large, 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 very difficult to achieve the ideal cooling and cooling effect only by relying on a single cooling of evaporative cooling.

In addition, the evaporative refrigeration device in this solution 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.

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. Effect.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the utility model provides an evaporative and electronic dual refrigeration cooling fan, in which the electronic refrigeration device can directly cool the air through a heat exchanger, and the heat exchange is sufficient, so that the air passes through The dual refrigeration of evaporative refrigeration and electronic refrigeration will significantly improve the cooling effect.

In order to achieve the above object, the technical solution adopted by the utility model is:

An evaporative and electronic dual cooling fan includes a box body with an air inlet and an air outlet, and an evaporative cooling system and an electric wind wheel placed in the box body. The cooling fan also includes an electronic refrigeration system installed in the box. The electronic refrigeration system adopts water cooling to dissipate heat. The cold surface of the electronic refrigeration chip is connected to the refrigeration heat exchanger, and the hot surface is connected to the heat dissipation heat exchanger. The heat dissipation heat exchanger and the water circulation circuit device is connected.

The above-mentioned evaporative and electronic dual cooling fan also includes an evaporative cooling system installed near the air inlet of the box body, which is composed of a humidifying filter material and a water circulation device connected to the humidifying filter material.

The water circulation device of the above-mentioned evaporation and electronic dual refrigeration system includes: a water circulation pipe; a water pump for providing power for the circulating water; and a shared water storage tank for storing the circulating water.

The beneficial effects of the utility model of evaporation and electronic dual refrigeration cooling fan are: driven by the electric wind wheel, the air enters the box body through the air inlet, and first evaporates and refrigerates through the humidifying filter material, and then passes through the refrigeration heat exchanger of the electronic refrigeration device. , for electronic refrigeration, after evaporation and electronic dual refrigeration, the cooling effect is obvious.

At the same time, because the evaporative refrigeration system can not only cool the passing air, but also cool the circulating water passing through it, so the hotter cooling circulating water of the electronic refrigeration system enters the water storage tank, and it will be mixed with the cooler circulating water of the evaporative refrigeration system. For heat exchange, if the power of the two refrigeration systems is well matched, the waste heat of the electronic refrigeration system can be self-treated inside the cooling fan, and the influence of the waste heat of the electronic refrigeration system on the room temperature can be avoided.

Detailed ways

In order to illustrate the technical solution of the utility model in more detail, the utility model will be further described below in conjunction with the accompanying drawings and embodiments. Apparently, the following embodiments are only some preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model.

Example 1:

As shown in Figure 1, this embodiment includes a box body 1 with an air inlet 3 and an air outlet 12, and an electronic refrigeration system and an evaporative refrigeration system in the box body 1. Each of the two refrigeration systems has a set of water circuit circulation devices, as follows :

The electronic refrigeration system includes an electronic refrigeration chip 10, which has a cold surface and a hot surface. 5 is connected with the heat dissipation heat exchanger 9 and the water storage tank 13, and is used to bring the heat in the heat dissipation exchanger 9 to the water storage tank 13; the self-priming pump 71 is connected with the water circulation pipe 5, and is used for circulating water Provide power.

The evaporative refrigeration system includes a humidification filter material 4, the air passing through the humidification filter material 4 will be evaporated and cooled by water, the humidity will increase, and the temperature will decrease; the water circulation pipe 2 is connected to the humidification filter material 4 to provide circulating water for it; the self-priming pump The water pump 72 is connected with the water circulation pipe 2 and is used to provide power for circulating water.

When the dual refrigeration air-conditioning fan in this embodiment is working, the air is driven by the electric wind wheel 6 and enters the box body 1 through the air inlet 3, and first passes through the evaporation and cooling of the humidifying filter material 4 to cool down, and then passes through the refrigeration of the refrigeration heat exchanger 11. Cool down, so that the air coming out from the air outlet 12 has undergone dual refrigeration of evaporation and electronic refrigeration, the cooling range is relatively large, and the cooling effect is obvious.

At the same time, since the humidification filter material 4 cools the passing air, it also cools the circulating water passing through it. Therefore, when the hotter heat dissipation circulating water of the electronic refrigeration system enters the water storage tank 13, it will interact with the evaporative refrigeration. The colder circulating water in the system performs heat exchange. If the power of the two refrigeration systems is well matched, the waste heat of the electronic refrigeration system can be self-treated inside the cooling fan, avoiding the influence of the waste heat of the electronic refrigeration system on the room temperature.

Example 2:

As shown in Figure 2, the difference between this embodiment and Embodiment 1 is that a part of the inlet pipe of the water circuit circulation pipe of the electronic and evaporative refrigeration systems is combined into one to form a shared inlet pipe, while the self-priming type Suction pump 7 is just installed on it. Compared with Embodiment 1, this embodiment can not only simplify the circulating water circuit in the cooling fan of the utility model, but also reduce a self-priming water pump, and reduce the cost of the cooling fan of the utility model.

Example 3:

As shown in FIG. 3 , compared with Embodiment 2, this embodiment replaces the self-priming water pump 7 in Embodiment 2 with a submersible pump 8 . Compared with self-priming pumps on the market, submersible pumps are more mature in technology and relatively lower in price, so this embodiment can further reduce the cost of the cooling fan of the present invention.

In the above three embodiments provided by the utility model, the refrigeration heat exchanger 11 is located near the air outlet 12, but obviously, the location of the refrigeration heat exchanger 11 is not limited to this, and can also be placed in other places in the box body 1. The location, for example, can also be placed between the electric wind wheel 6 and the humidification filter material 4, as long as the cooling heat exchanger 11 can fully contact with the air flowing through the box body 1 for heat exchange.

Fig. 4 is a structural schematic diagram of an embodiment of the heat dissipation heat exchanger 9 of the present invention. As shown in FIG. 4 , the heat dissipation heat exchanger 9 of this embodiment is a channel-type water-cooled heat exchanger, which consists of a shell 91 , heat dissipation fins 92 , and water flow channels 93 . The direction of the arrow is the direction of the circulating water flow. When the circulating water passes through the long channel 93, it will exchange heat with the cooling fins 92, thereby taking away the heat on the cooling heat exchanger.

Fig. 5 is a structural schematic diagram of an embodiment of the refrigeration heat exchanger 11 of the present invention. As shown in FIG. 5 , the refrigeration heat exchanger of this embodiment is composed of refrigeration fins 111 and air ducts 112 . The direction of the dotted arrow is the direction of air flow. When the air flows through the air duct 112, it will exchange heat with the cooling fins 111 to achieve cooling and cooling.
