[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-4 A heat dissipation base for a test transformer control box shown in the figure includes a control box body 1, an outer box body 2 and a movable bearing groove 21 sealed and slidable in the outer box body 2, a water storage chamber 22 for storing cooling water is arranged between the outer box body 2 and the movable bearing groove 21, and a water inlet pipe 23 connected with the water storage chamber 22 is arranged on the outer box body 2; a hollow chamber 24 is arranged inside the movable bearing groove 21, and the water storage chamber 22 and the hollow chamber 24 are connected through two groups of water pipes 25, and the heat dissipation base is placed by placing the control box body 1 inside the movable bearing groove 21, and then using the inner wall of the movable bearing groove 21 to fit the outer surface of the control box body 1 in all directions, and then passing cooling water into the water storage chamber 22, and the cooling water flows into the hollow chamber 24 through the water pipe 25, thereby absorbing and taking away the heat generated by the control box body 1, so that the control box body 1 will not overheat.

[0025] In one embodiment, the water pipe 25 is arranged in two groups on both sides of the outer box body 2. The water pipe 25 includes a connecting pipe 3 connected to the hollow chamber 24 and a one-way valve 31 arranged on the outer box body 2 and connecting the water storage chamber 22 with the water pipe 25. The flow direction of one group of one-way valves 31 is toward the water storage chamber 22, and the flow direction of the other group of one-way valves 31 is toward the connecting pipe 3. The movable groove 21 and the outer box body 2 can move relatively. When cooling water is injected into the water storage chamber 22, the movable groove 21 is pressed down, and then the cooling water will flow to the connecting pipe 3 through the one-way valve 31 on one side, and then enter the hollow chamber 24, and flow through the hollow chamber 24 to the connecting pipe 3 on the other side, and then flow back to the inside of the water storage chamber 22 through the one-way valve 31 on this side, thereby achieving the effect of water flow, and then the heat can be taken away by the cooling water after absorbing heat.

[0026] In one embodiment, a connecting hose 32 connecting the connecting pipe 3 and the hollow chamber 24 is further provided between the connecting pipe 3 and the movable socket 21. Since the movable socket 21 needs to move relative to the outer box body 2, the connecting hose 32 is provided so that the connecting pipe 3 and the hollow chamber 24 can always be kept connected during the movement of the movable socket 21.

[0027] In one embodiment, a heat conducting plate 4 connected to the hollow chamber 24 is provided on the inner wall of the movable bearing groove 21. The heat conducting plate 4 is made of a metal material with high thermal conductivity. Through the setting of the heat conducting plate 4, it is ensured that the heat of the outer wall of the control box body 1 can be quickly introduced into the cooling water in the hollow chamber 24 through the heat conducting plate 4, which facilitates heat dissipation.

[0028] In one embodiment, an overflow pipe 5 connected to the water storage chamber 22 is further provided on the outer box body 2. The height of the overflow pipe 5 is higher than the water inlet pipe 23. Since the water storage chamber 22 needs to be filled with water for use, and in order to ensure the fluidity of the water body, the inside of the device cannot be filled, and the overflow pipe 5 is provided. After the water body in the water storage chamber 22 is filled to a certain height, it will overflow outward through the overflow pipe 5, which is convenient for the staff to observe the degree of water filling, so that they can stop filling cooling water in time. At the same time, the setting of the overflow pipe 5 can also facilitate the downward pressure of the movable bearing groove 21, so that the water body in the water storage chamber 22 can flow faster to the hollow chamber 24, thereby accelerating the heat dissipation of the control box body 1.

[0029] In one embodiment, a spring 6 is further provided between the outer box body 2 and the movable bearing groove 21. After the movable bearing groove 21 is pressed down, the spring 6 enables it to rebound, thereby enabling the movable bearing groove 21 to realize the circulation of internal cooling water during the up and down reciprocating motion.

[0030] In one embodiment, a limiting ring frame 7 for limiting the movable bearing groove 21 is further provided on the inner wall of the outer box body 2. In order to prevent the movable bearing groove 21 from being pressed down too much and causing local structural damage due to excessive water pressure, the limiting ring frame 7 is provided to ensure that the lowering degree of the movable bearing groove 21 is fixed, so that the water flow can be maintained at an appropriate flow rate to achieve circulating heat dissipation.

[0031] In one embodiment, recesses 8 are further provided on both sides of the movable receiving groove 21. In order to facilitate the control box body 1 to be conveniently placed in the movable receiving groove 21 and taken out, the recesses 8 are provided. The lower opening height of the recess 8 is lower than the handle position height of the control box body 1, thereby facilitating operation and placement.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
