[0033] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figure 1-6 As shown, a control cabinet cooling structure of the utility model includes a cabinet body 1, a liquid cooling box 2 and a fan 3.

[0035] Among them, cabinet 1 is the main frame of the control cabinet, which is used to install electrical components, control switches and connecting lines. Cabinet 1 is a sealed box structure, which is convenient for isolating electrical components from the external environment, so that the control cabinet can adapt to harsh environments with more dust or more water vapor.

[0036] The liquid cooling box 2 is used to liquid cool the control cabinet. A mounting hole 101 is opened on one side of the cabinet 1. The liquid cooling box 2 is fixedly arranged on the outside of the cabinet 1 and the mounting hole 101 is blocked. A fin plate group 21 is fixedly arranged on the liquid cooling box 2, and the fin plate group 21 passes through the mounting hole 101; Figure 1 As shown, the liquid cooling box 2 is arranged outside the cabinet 1, and its main body and the joints for circulating the liquid cooling medium are not located in the cabinet 1, so there will be no problem of leakage of the liquid cooling medium causing a short circuit inside the control cabinet. However, since the fin plate group 21 is fixedly connected to the liquid cooling box 2 and is located in the cabinet 1, the fin plate group 21 can achieve a certain liquid cooling effect.

[0037] The fan 3 is used to drive the air to flow. The fan 3 is fixedly arranged on the fin plate group 21. The fan 3 is used to realize the flow of air, so that a flowing airflow for heat exchange with the fin plate group 21 is formed in the cabinet 1, and a good cooling effect is achieved under the premise of fully protecting the electrical components inside the cabinet 1.

[0038] like Figure 2 As shown, the fin plate group 21 is preferably configured to include a plurality of fin plates 211, the plurality of fin plates 211 are arranged in parallel and at intervals, and are fixedly connected to the liquid cooling box 2, and the width direction of the fin plate 211 is perpendicular to the liquid cooling box 2. By utilizing this structure, a heat dissipation channel (the gap between two adjacent fin plates 211) can be formed between the plurality of fin plates 211, and when the flowing air passes through this heat dissipation channel, it can fully exchange heat with the fin plate 211.

[0039] Regarding the installation position of the fan 3 and the fin plate assembly 21, the utility model provides two specific structures:

[0040] The first one is Figure 1 As shown, the fan 3 is fixedly arranged on the side of the fin plate group 21 away from the liquid cooling box 2. This method can increase the number of fans 3, thereby increasing the coverage area of ​​the air flow inside the cabinet 1.

[0041] The second structure is Figure 3 As shown, the fan 3 is fixedly arranged at the end of the multiple fin plates 211 in the length direction, so that the air driven by the fan 3 can fully flow through the gaps between the multiple fin plates 211, thereby improving the heat exchange effect.

[0042] When the installation positions of the fan 3 and the fin plate group 21 are in the second structure, a control cabinet cooling structure of the utility model further includes a housing 4 and an air guide 5 .

[0043] Among them, the shell 4 is used to prevent air from being lost when flowing through the fin plate group 21. It is preferred that the shell 4 is fixedly set at one end of the multiple fin plates 211 away from the liquid cooling box 2. When the fan 3 drives the air to blow in from the upper ends of the multiple fin plates 211, the air can flow through the gaps between the multiple fin plates 211 and then blow out from the lower ends of the fin plates 211, thereby preventing the air from being blown out from the end of the fin plates 211 away from the liquid cooling box 2, thereby ensuring the heat exchange effect of the air. Similarly, the shell 4 can also be fixedly set at one end of the multiple fin plates 211 away from the fan 3, and an air outlet 401 can be opened on the shell 4, such as Figure 3 As shown, when the fan 3 drives air to blow in from the upper ends of the plurality of fin plates 211 , the air can flow through the gaps between the plurality of fin plates 211 and then be blown out from the air outlet 401 .

[0044] The air guide 5 is used to adjust the direction of air flow. The air guide 5 is fixedly arranged on the housing 4 and corresponds to the position of the air outlet 401 .

[0045] Specifically, the wind deflector 5 is preferably configured to include a fixing frame 51 and a plurality of wind shields 52. The fixing frame 51 is fixedly arranged on the housing 4 and corresponds to the position of the air outlet 401. The wind shields 52 are rotatably arranged in the fixing frame 51. The plurality of wind shields 52 are arranged in parallel and at intervals. The wind shields 52 can guide the flow of air. By rotating the wind shields 52, the flow direction of the air blown out from the air outlet 401 can be controlled. In order to facilitate unified control of the plurality of wind shields 52, a control rod 53 can also be provided in the wind deflector 5, a connecting rod 521 is fixedly arranged at one end of the wind shield 52, the end of the connecting rod 521 away from the wind shield 52 is rotatably connected to the fixing frame 51, the control rod 53 is arranged between the plurality of connecting rods 521, and is rotatably connected to the plurality of connecting rods 521, such as Figure 5 and Figure 6 As shown, when the control rod 53 is pulled, the multiple connecting rods 521 and the wind shield 52 can be driven to rotate, thereby controlling the flow direction of the air; after the control direction of the air deflector 5 is adjusted, in order to prevent the direction from changing due to the blowing of the air, a fixing bolt 511 can be connected to the fixing frame 51 by threaded engagement, so that the front section of the fixing bolt 511 selectively abuts against the control rod 53, as shown in FIG. Figure 5 As shown, when the fixing bolt 511 is screwed downward, the fixing bolt 511 can be pressed against the control rod 53 to prevent the control rod 53 from shaking. When the air flow direction needs to be adjusted, the fixing bolt 511 can be screwed upward.

[0046] The working principle of a control cabinet cooling structure of the utility model is as follows:

[0047] After the liquid cooling box 2 is connected to the liquid cooling medium circulation device and the fan 3 is started, the fan 3 drives the air in the cabinet 1 to circulate, so that the heat generated by the electrical components is exchanged with the fin plate group 21 to cool the control cabinet.

[0048] When the layout of electrical components in the control cabinet is relatively concentrated, the wind shield 52 can be driven to rotate by moving the control rod 53 so that air can blow to the installation position of the electrical components, and the control rod 53 can be supported and fixed with fixing bolts 511 to enhance the cooling effect of the cooling structure.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
