Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Unless otherwise specified, the technical means used in the implementation examples are conventional means well known to those skilled in the art.

Referring to Figures 1 to 3, the present utility model discloses a power control box, comprising a box body 1, and a first screen plate 2 parallel to each other is arranged in the box body 1 near its bottom, that is, the first screen plate 2 and the box body The bottom of 1 forms a cavity, and a cavity is formed between the two first screen plates 2 . A metal pipe 3 is laid between the two first mesh plates 2, that is, the metal pipe 3 is placed in the cavity formed by the two first mesh plates 2, and the specific placement method is shown in Figure 3, which is arranged in a circle; the box body 1 A cooling fan 4 is slidably arranged inside and below the first screen plate 2, that is, the cooling fan 4 is arranged in the cavity formed by the first screen plate 2 and the bottom of the box body 1; the top of the box body 1 is provided with a cooling box 5, The heat dissipation box 5 and the box body 1 are communicated through the second mesh plate 6 , and an exhaust fan 7 is arranged on the side wall of the heat dissipation box 5 . It should be noted that a top plate is shared between the heat dissipation box 5 and the box body 1, and the second mesh plate 6 is arranged on the top plate, so that the heat dissipation box and the box body 1 are communicated, so that the hot air in the box body 1 is in the cooling fan. Under the action of 4, it blows into the cooling box 5 and is exhausted by the exhaust fan 7 on the cooling box.

For the cooling effect, the cooling can be achieved by the metal material of the metal tube 3 itself. Under the action of the cooling fan, the lower temperature air in the cavity where the metal tube is located (the temperature here is lower than the temperature in the box) is blown into In the upper region of the first screen plate 2, the temperature is lowered. However, the cooling effect of relying solely on the metal tube itself is especially bad in summer. Therefore, in order to increase the cooling effect, a cooling liquid is introduced into the metal pipe 3, and the cooling liquid is preferably water, and can also be other substances, such as refrigerated air. Specifically: both ends of the metal pipe 3 protrude out of the side wall of the box 1 and communicate with the same water tank 18. At the same time, one end of the metal pipe 3 is communicated with the water tank 18 through the water pump 19, and the other end is provided with a valve . The water in the water tank 18 is pumped into the metal pipe 3 by the water pump 19, and at the same time, the water enters the water tank 18 from the other end of the metal pipe 3 again, thereby realizing the circulation of water.

In order to avoid the process of water circulating between the metal pipe and the water tank, when the water temperature in the water tank is close to the temperature in the tank and cannot be cooled more quickly, a cooling chip can be selectively installed in the water tank to reduce the temperature in the water tank. Water cools down. However, after the water enters the metal pipe after cooling down, condensation water may be formed on the side wall of the box and on the electrical components due to the temperature difference between the water temperature and the box, which may lead to the risk of short circuit of the electrical components. Therefore, the temperature difference between the water and the box can be reduced by adjusting the cooling temperature of the refrigerating sheet, thereby reducing the risk of condensed water formation. Alternatively, a moisture absorbing plate 28 can be provided on the first mesh plate 2 above the metal pipe 3 to absorb moisture from the air blown by the cooling fan. This method can also solve the problem of condensation water formed due to a large temperature difference. The moisture absorbing plate 28 can be provided as many as needed. In order to allow the air blown by the cooling fan to pass through the moisture absorbing plate 28, the moisture absorbing plate 28 is covered with micro-holes for air to pass through. The moisture absorbing board 28 may be a rock wool board. Of course, directly using room temperature water, combined with the use of exhaust fans and cooling fans, can also cool the box well, and the box can achieve a safe operating environment for electrical components.
