[0036] Next, refer to Figures 1 to 5Describe a circulating cooling system and an electrical device according to an embodiment of the present application.

[0037] Referring to Figures 1 to 5 As shown, an embodiment of the present application provides a circulating cooling system. This circulating cooling system includes: an inlet pipe 1, an outlet pipe 2, and a plurality of heat dissipation components 3. Among them, the inlet pipe 1 and the outlet pipe 2 are arranged side by side. The inlet pipe 1 is used to introduce a heat dissipation medium, and the outlet pipe 2 is used to output the returned heat dissipation medium. The plurality of heat dissipation components 3 are used to connect a plurality of heat generating devices in the electrical device that can generate heat. The heat dissipation component 3 includes a heat conducting member 301, a first liquid distribution connector 302, and a second liquid distribution connector 303. Among them, the heat conducting member 301 is used to connect with the heat generating device. The inside of the heat conducting member 301 is hollow to form a cavity. One end of the first liquid distribution connector 302 is connected to the heat conducting member 301, and the other end of the first liquid distribution connector 302 is connected to the inlet pipe 1. One end of the second liquid distribution connector 303 is connected to the heat conducting member 301, and the other end of the second liquid distribution connector 303 is connected to the outlet pipe 2. The heat dissipation medium introduced through the inlet pipe 1 flows into the cavity of the heat conducting member 301 through the first liquid distribution connector 302. The heat released by the heat generating device is transferred to the heat conducting member 301 and absorbed by the heat dissipation medium in the cavity of the heat conducting member 301. The heat dissipation medium takes away the heat of the heat generating device, and then the heat dissipation medium flows to the outlet pipe 2 through the second liquid distribution connector 303. The working process of each heat dissipation component 3 is like this. It should be noted that the heat dissipation medium can be water or other common coolants.

[0038] Furthermore, the heat conducting member 301 is in a flat plate shape. Preferably, the heat conducting member 301 is made of a material with heat conductivity, which can be, but is not limited to, copper. The plate surface of the heat conducting member 301 is attached to the heat generating device. A plurality of heat conducting fins 3013 are arranged in the internal cavity of the heat conducting member 301. The plurality of heat conducting fins 3013 are arranged in parallel at intervals, and the heat conducting fins 3013 are in contact with the inner wall surfaces of the two large surfaces of the heat conducting member 301 at the same time. By setting the heat conducting fins 3013, the heat conduction effect of the heat conducting member 301 on the heat generating device can be enhanced, and the efficiency of the heat transfer from the heat generating device to the heat conducting member 301 can be improved. At the same time, by arranging the heat conducting fins 3013 in the heat conducting member 301, a flow channel is formed between two adjacent heat conducting fins 3013 in the heat conducting member 301. The flow channels are distributed throughout the cavity of the heat conducting member 301, and the heat dissipation medium can flow through each flow channel, increasing the orderliness of the flow of the heat dissipation medium inside the heat conducting member 301 and avoiding the mixing of the heat dissipation medium that exchanges heat with the heat generating device and the newly flowing heat dissipation medium into the heat conducting member 301, which affects the heat exchange effect and efficiency between the heat conducting member 301 and the heat generating device.

[0039] Preferably, the diameter of the first liquid separation connector 302 is smaller than that of the liquid inlet pipe 1, and the diameter of the second liquid separation connector 303 is smaller than that of the liquid outlet pipe 2. When the heat dissipation medium flows from the liquid inlet pipe 1 to the first liquid separation connector 302, the change in diameter changes the pressure of the heat dissipation medium, thereby increasing the flow rate of the heat dissipation medium flowing into the flow channel and within the flow channel, and further improving the heat conduction and heat absorption effects of the heat conducting member 301 on the heating device. The same applies to the second liquid separation connector 303 and the liquid outlet pipe 2.

[0040] Preferably, both the first liquid separation connector 302 and the second liquid separation connector 303 are flexible hoses, which can freely adjust the extension directions of the first liquid separation connector 302 and the second liquid separation connector 303, facilitating the adjustment of the relative position between the heat conducting member 301 and the heating device.

[0041] Further, the heat conducting member 301 is provided with a first joint 3011 and a second joint 3012 at intervals. One end of the first liquid separation connector 302 far from the liquid inlet pipe 1 is connected to the first joint 3011, and one end of the second liquid separation connector 303 far from the liquid outlet pipe 2 is connected to the second joint 3012.

[0042] In addition, the heat conducting member 301 is also provided with fixing holes, which are independently arranged from the internal cavity of the heat conducting member 301. The fixing holes are used for passing through fasteners such as screws to fix the heat conducting member 301 to the heating device.

[0043] Further, the liquid inlet pipe 1 is formed with a plurality of first bending portions to change the extension direction of the liquid inlet pipe 1. Similarly, the liquid outlet pipe 2 is formed with second bending portions at positions corresponding to the first bending portions, so that the liquid outlet pipe 2 is bent at the same position as the liquid inlet pipe 1, so that the liquid inlet pipe 1 and the liquid outlet pipe 2 are always arranged side by side.

[0044] Further, the liquid inlet pipe 1 includes a primary liquid separation unit 101 and a secondary liquid separation unit 102. By changing the extension direction of the liquid inlet pipe 1 through the first bending portion, the liquid inlet pipe 1 is formed with a primary liquid separation unit 101 and a secondary liquid separation unit 102 that are interconnected and arranged in layers. After the present circulating cooling system is installed in the electrical equipment, the primary liquid separation unit 101 is located above the secondary liquid separation unit 102 in terms of layering.

[0045] The liquid outlet pipe 2 includes a primary liquid outlet unit 201 and a secondary liquid outlet unit 202. The extension direction of the liquid outlet pipe 2 is changed by the second bending part, so that the liquid outlet pipe 2 forms the primary liquid outlet unit 201 and the secondary liquid outlet unit 202 which are interconnected and arranged in layers. After installing this circulating cooling system to the electrical equipment, the primary liquid outlet unit 201 is located above the secondary liquid outlet unit 202. The primary liquid outlet unit 201 is arranged in parallel with the primary liquid distribution unit 101. Preferably, the primary liquid outlet unit 201 is arranged parallel to the primary liquid distribution unit 101. The secondary liquid outlet unit 202 is arranged in parallel with the secondary liquid distribution unit 102. Preferably, the secondary liquid outlet unit 202 is arranged parallel to the secondary liquid distribution unit 102. With such an arrangement, the primary liquid distribution unit 101, the primary liquid outlet unit 201, the secondary liquid distribution unit 102, and the secondary liquid outlet unit 202 are spirally arranged in layers within the electrical equipment, ensuring that this circulating cooling system has a sufficiently long flow path, improving the utilization rate of the internal space of the electrical equipment, and the pipeline distribution is regular without the situation of chaotic pipeline distribution.

[0046] Furthermore, this circulating cooling system further includes a heat exchange device (not shown in the figure). The heat exchange device can be a common chiller in the prior art, specifically including a pump body and a compressor. This circulating cooling system further includes a liquid storage tank (not shown in the figure). The liquid storage tank is used to store the heat dissipation medium. The liquid storage tank is connected to the heat exchange device. Preferably, both the heat exchange device and the liquid storage tank are arranged outside the electrical equipment. Under the action of the pump body, the heat dissipation medium in the liquid storage tank flows into the heat exchange device for heat exchange and cooling and then flows back to the liquid storage tank. The heat dissipation medium after heat exchange flows into the inlet pipe 1, thereby ensuring the heat dissipation effect on the heat generating device, and at the same time making the heat dissipation medium have a certain pressure so that the heat dissipation medium can circulate between the liquid storage tank, the inlet pipe 1, and the liquid outlet pipe 2, and ensuring that the heat dissipation medium can flow into each heat dissipation component 3.

[0047] Furthermore, this circulating cooling system further includes an inlet connector 4 and an outlet connector 5. Among them, the inlet connector 4 is arranged on the inlet pipe. The liquid storage tank is provided with a liquid supply port and a return port. The inlet connector 4 is connected to the liquid supply port, and the outlet connector 5 is connected to the return port. Preferably, the inlet connector 4 is arranged on the primary liquid distribution unit 101. The outlet connector 5 is arranged on the outlet pipe. Preferably, the outlet connector 5 is arranged on the primary liquid distribution unit. With such an arrangement, the inlet connector 4 and the outlet connector 5 are at a high position, ensuring the fluidity of the heat dissipation medium in the inlet pipe 1 and the liquid outlet pipe 2, so as to ensure that there is heat dissipation medium circulating in each heat dissipation component 3.

[0048] Further, as described above, the number of the heat dissipation members 3 is multiple. A part of the multiple heat dissipation members 3 is arranged in the primary liquid distribution unit 101 and the primary liquid outlet unit 201, and another part of the multiple heat dissipation members 3 is arranged on the secondary liquid distribution unit 102 and the secondary liquid outlet unit 202. All the heat dissipation members 3 are dispersedly distributed along the extension axial direction of the liquid inlet pipe 1 and the liquid outlet pipe 2, so as to dissipate heat from each heating device in the electrical equipment through the multiple heat dissipation members 3.

[0049] Preferably, the secondary liquid distribution unit 102 is annular. Correspondingly, the secondary liquid outlet unit 202 is also annular. More preferably, both the secondary liquid distribution unit 102 and the secondary liquid outlet unit 202 are annular in a quadrilateral shape. A plurality of heat dissipation members 3 are arranged on each side edge of the secondary liquid distribution unit 102 and the secondary liquid outlet unit 202, effectively expanding the distribution range of the multiple heat dissipation members 3, thereby ensuring the comprehensiveness of heat conduction and heat dissipation of the multiple heating devices of the electrical equipment by this circulating cooling system.

[0050] In summary, the circulating cooling system provided by this application realizes a multi-outflow and multi-point heat dissipation mode through a complete set of cooling system, can meet the comprehensive heat dissipation requirements of the electrical equipment using this circulating cooling system, ensure that each device in the electrical equipment is within an appropriate temperature range, and does not require separate configuration of heat dissipation devices for each device, making full use of the internal space of the electrical equipment and facilitating the operating parameters and operating status of this circulating cooling system.
