When the water curtain is laid in the wall body interlayer, the periphery of the water curtain can be tensioned and positioned on the surface of the adjacent wall body interlayer, and one side surface of the water curtain can be attached to the wall body interlayer. The thickness of cascade can be rationally set up according to the intermediate layer interval of wall body intermediate layer, include and be not limited to the thickness of cascade and equal the intermediate layer interval of wall body intermediate layer.
When the packing balls are used as the water gathering pieces 3, the packing balls are uniformly filled in the wall body interlayer, and at the moment, the bottom of the wall body interlayer is provided with a screen-shaped baffle and other structures for limiting the positions of all the packing balls in the wall body interlayer and preventing the packing balls from entering the lower water tank 2.
The cabinet cooler may be provided with a screen 5 in addition to a screen-like baffle for defining the position of the packing balls. For the water curtain, the screen 5 may be used to filter impurities in the cooling medium and prevent the impurities from entering the lower tank 2, and of course, may also assist in positioning and installing the screen 5 in the interlayer of the wall. In the case of the packing balls, the screen 5 can serve on the one hand as the aforementioned screen-like baffle and on the other hand for filtering the cooling medium.
The screen 5 may be installed at a lower edge of the water collecting member 3 and transversely stretched between the wall body interlayer and the top surface of the lower header 2. For example, the screen 5 may be disposed horizontally or obliquely in the cabinet 01, and the size of the screen 5 is not smaller than that of the top surface of the lower tank 2. In addition, the size of the screen 5 may be smaller than that of the top surface of the lower tank 2 according to the specific structure of the wall body interlayer, and at this time, the outer peripheral edge of the screen 5 is fixed to the outer layer of the wall body interlayer, and the inner peripheral edge of the screen 5 is fixed to the inner layer of the wall body interlayer. Taking the horizontal projection of the interlayer of the wall body as a rectangular-square cavity structure as an example, the screen 5 is correspondingly configured into a rectangular-square structure.

The hydraulic control valve and the aforementioned liquid level sensor are both connected to a controller, and the controller may control the opening degree of the hydraulic control valve according to a detection signal of the liquid level sensor, including, but not limited to, increasing the opening degree of the hydraulic control valve when the liquid level sensor detects that the liquid level in the header tank 1 is higher than a set value and decreasing the opening degree of the hydraulic control valve when the liquid level sensor detects that the liquid level in the header tank 1 is lower than the set value.
As for the lower water tank 2 of the cabinet cooling device, the water tank opening can be connected with the outer port of the wall body interlayer in a sealing way, in other words, the lower end of the wall body interlayer is completely sealed by the lower water tank 2, so that external impurities are prevented from entering the wall body interlayer and the lower water tank 2, and objects in the wall body interlayer and the lower water tank 2 are prevented from leaking outwards.
Further, the cabinet cooling device is further provided with a pump 6 and a water return pipe 7 between the upper water tank 1 and the lower water tank 2. An inlet of the return pipe 7 is connected to the lower water tank 2, and is usually connected to the bottom of the lower water tank 2, so as to ensure that the cooling medium in the lower water tank 2 can be guided from the return pipe 7; the outlet of the return pipe 7 is connected to the upper tank 1, usually to the top of the upper tank 1, to ensure that the lower tank 2 can safely and reliably return as much cooling medium as possible to the upper tank 1. The pump 6 is connected to a return pipe 7 between the upper and lower water tanks 1 and 2.
In order to improve the cooling effect of the cabinet cooling device on the cabinet 01, a cooler is connected to the return pipe 7, and the cooler is used for cooling the cooling medium flowing through the return pipe 7, so as to reduce the temperature of the cooling medium returning to the upper tank 1. The cooling principle of the cooler includes, but is not limited to, air cooling.
Aiming at the cabinet cooling device provided by the utility model, the utility model also provides an electric appliance cabinet, wherein a wall body interlayer is arranged on the periphery of the electric appliance cabinet, the upper water tank 1 and the lower water tank 2 of the cabinet cooling device are respectively arranged at the upper end and the lower end of the wall body interlayer, and the structures of the water collecting piece 3 and the like of the cabinet cooling device are arranged in the wall body interlayer.
For the electric appliance cabinet, the upper water tank 1 and the lower water tank 2 of the cabinet cooling device should have certain sealing performance, so as to avoid water seepage to the electric parts inside the electric appliance cabinet.
In addition, in order to ensure the normal operation of the electric appliance cabinet, a cavity for accommodating the electric parts is arranged in the electric appliance cabinet; the water absorbing layer is arranged in the cavity, and once condensed water or seeped water appears on the inner peripheral wall surface of the wall body interlayer due to the operation of the cabinet cooling device, the water absorbing layer can absorb the condensed water or the seeped water, so that the corrosion damage of electrical parts in the cavity is avoided.
The water absorbing layer can be arranged close to the inner peripheral wall surface of the wall body interlayer, and can also be directly attached to the inner peripheral wall surface of the wall body interlayer, and the water absorbing layer is specifically arranged according to the material of the water absorbing layer. For example, when the water-absorbent layer is provided as a film-like water-absorbent material, the film-like water-absorbent material is laid and fixed along the inner peripheral wall surface of the wall sandwich.
Above-mentioned meaning on layer that absorbs water not only lies in eliminating for all kinds of risks that the cabinet ware introduced because of addding cabinet cooling device to the electrical apparatus cabinet specifically is for locating outdoor switch board as an example, when meetting the plum rainy season, long-time precipitation can lead to the moisture in this switch board overweight, greatly increased the short circuit risk of switch board inner circuit, at this moment, the layer that absorbs water can reduce the humidity in the switch board, ensures the operation safety of switch board to a certain extent.
