Description

Technical Field

[0001] The present invention relates to the technical field of power supply heat dissipation structures, and in particular to an oil-cooled heat dissipation structure for a high-power power supply. Background Art

[0002] High-power power supplies generate a lot of heat during use. If they are not cooled in time, the internal electrical components of the power supply will be damaged, affecting the normal processing and production. In order to improve the heat dissipation efficiency of high-power power supplies, an oil-cooled heat dissipation structure is usually set in the high-power power supply. The circulation of oil-cooling medium is used to keep the temperature of the high-power power supply within a safe range.

[0003] The existing utility model with publication number CN217445734U discloses an oil-cooled power supply, including an oil-cooling box, a power supply body arranged in the oil-cooling box, and a circulation component arranged on one side of the oil-cooling box; it solves the technical problem in the prior art that the heat of the internal cooling oil of the oil-cooled power supply cannot be quickly dissipated in harsh environments, affecting the normal use of the power supply, and realizes that the heat of the cooling oil of the oil-cooled power supply can be effectively dissipated, ensuring the normal use of the power supply.

[0004] In the above technical solution, in order to realize the circulation of the oil-cooling medium, a first pipeline and a second pipeline are set. However, when the power supply specification is large, in order to make the pipeline cover the power supply, the length of the first pipeline and the second pipeline will be lengthened, so that the temperature of the oil-cooling medium at the end positions of the flow direction in the first pipeline and the second pipeline will be relatively high, resulting in a relatively weak cooling effect of the pipeline, thereby reducing the heat dissipation efficiency of the power supply.

[0039] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figure 1-10 As shown, a high-power power supply oil-cooling heat dissipation structure of the present invention includes a heat dissipation cover 1 and a heat dissipation oil circuit 2.

[0041] The heat dissipation cover 1 is a prior art, and is the outer shell of a high-power power supply.

[0042] The heat dissipation oil circuit 2 is used to circulate the oil cooling medium. The heat dissipation oil circuit 2 includes an inlet channel 21, an outlet channel 22 and a heat dissipation channel 23. The inlet channel 21 and the outflow channel 22 are both opened in the heat dissipation cover 1, and the inlet channel 21 and the outflow channel 22 are arranged in parallel. The heat dissipation channel 23 is opened in the heat dissipation cover 1, and its two ends are respectively connected to the inlet channel 21 and the outflow channel 22. There are multiple heat dissipation channels 23, and their inner diameters are smaller than the inner diameters of the inlet channel 21 and the outflow channel 22; Figure 3As shown, multiple heat dissipation channels 23 are connected between the inflow channel 21 and the outflow channel 22, so that the heat dissipation medium can be divided into multiple paths when flowing from the inflow channel 21 to the outflow channel 22. Compared with the method of using a continuous S-shaped pipe, the length of the channel can be greatly reduced, preventing the temperature of the oil-cooling medium from rising too high when flowing in the channel, thereby affecting the heat dissipation efficiency of the power supply; at the same time, because the inner diameter of the heat dissipation channel 23 is smaller than the inner diameter of the inflow channel 21 and the outflow channel 22, the oil-cooling medium in the inflow channel 21 can fully flow into each heat dissipation channel 23, preventing the problem of no oil-cooling medium flowing in individual heat dissipation channels 23.

[0043] In order to ensure the normal operation of the heat dissipation oil circuit 2, two joints 3 and two connecting pipes 4 can be provided on the heat dissipation cover 1. The joints 3 are fixedly provided on the heat dissipation cover 1, and the connecting pipes 4 are fixedly provided on the heat dissipation cover 1. One connecting pipe 4 is connected to one joint 3 and the inflow channel 21, and the other connecting pipe 4 is connected to the other joint 3 and the outflow channel 22; Figure 10 As shown, by providing a connecting pipe 4 to connect the heat dissipation oil circuit 2 and the joint 3, the two joints 3 can be arranged adjacent to each other, which not only facilitates the connection of the pipeline to the joint 3, but also facilitates the protection of the joint 3.

[0044] Furthermore, in order to improve the flow uniformity of the oil cooling medium when it enters the inflow channel 21, a diverter plate 5 can be provided, so that the diverter plate 5 is fixedly arranged in the inflow channel 21 and located at one end of the connecting pipe 4, and a plurality of diverter grooves 501 are divergently opened on the diverter plate 5; Figure 3 and Figure 4 As shown, when the oil-cooling medium enters the inflow channel 21, the diversion of the diverter groove 501 can make the oil-cooling medium flow into the inflow channel 21 in a divergent manner; in addition, the side of the diverter plate 5 close to the connecting pipe 4 can be set to be inclined, so that the thickness of the diverter plate 5 gradually increases from the end away from the heat dissipation channel 23 to the end close to the heat dissipation channel 23. When the oil-cooling medium enters the inflow channel 21, the oil-cooling medium can flow toward the side of the inflow channel 21 away from the heat dissipation channel 23, rather than flowing toward the side of the heat dissipation channel 23, and the uniformity of the oil-cooling medium entering the heat dissipation channel 23 can also be improved.

[0045] In order to prevent the joint 3 from affecting the device when oil leakage occurs, a fixing box 6 and a sealing cover 7 can also be provided. The fixing box 6 is fixedly provided on the heat dissipation cover 1, and the fixing box 6 is located on the outside of the two joints 3. The sealing cover 7 is detachably fixed on the fixing box 6 to seal the opening of the fixing box 6. Two reinforcement cylinders 71 are provided on the sealing cover 7 by means of threaded engagement. The reinforcement cylinder 71 is sleeved with the joint 3; Figure 5 and Figure 6As shown, the fixing box 6, the sealing cover 7 and the reinforcement cylinder 71 are used to seal the joint 3. When oil leakage occurs at the joint 3, the oil cooling medium will not flow into the surrounding environment, thereby achieving a certain protective effect.

[0046] Furthermore, the end of the connector 3 away from the heat dissipation cover 1 can be set to a conical shape, so that the outer diameter of the end of the connector 3 away from the heat dissipation cover 1 is smaller than the outer diameter of the end of the connector 3 close to the heat dissipation cover 1, which can facilitate the connection of the oil cooling medium pipeline and the connector 3; correspondingly, the inner diameter of the reinforcement cylinder 71 is larger than the outer diameter of the end of the connector 3 away from the heat dissipation cover 1, and smaller than the outer diameter of the end of the connector 3 close to the heat dissipation cover 1. When the reinforcement cylinder 71 is rotated, the reinforcement cylinder 71 can be made to resist the outer wall of the connector 3, thereby improving the sealing effect of the connector 3.

[0047] Furthermore, a partition plate 72 can be fixedly provided on the sealing cover 7 so that the partition plate 72 is in contact with the heat dissipation cover 1 and the fixed box 6. The partition plate 72 divides the cavity in the fixed box 6 into two parts, and the two joints 3 are respectively located on both sides of the partition plate 72. When both joints 3 leak oil, the two joints 3 can be sealed separately to prevent the flow direction of the oil-cooling medium from being affected.

[0048] As a preferred embodiment, for the fixed connection between the sealing cover 7 and the fixing box 6, a card slot 601 and a slide groove 602 can be provided on the fixing box 6, so that the sealing cover 7 is slidably set in the slide groove 602, and a hook 73 is fixedly provided on the sealing cover 7, so that the hook 73 is engaged with the card slot 601; Figure 5 As shown, the sealing cover 7 is assembled and disassembled by sliding the sealing cover 7 and the sliding groove 602 , and the sealing cover 7 is fixed by the engagement of the hook 73 and the locking groove 601 .

[0049] Furthermore, in order to improve the heat dissipation effect of the power supply, fins 8 can be provided, so that a plurality of fins 8 are fixedly provided on the inner and outer sides of the heat dissipation cover 1 to increase the heat dissipation area of ​​the power supply. The fins 8 close to the hook 73 can also be spaced 1-3 mm apart from the hook 73, such as Figure 6 As shown, by setting a gap of 1-3 mm between the fin 8 and the hook 73, the hook 73 is not easily separated from the slot 601, thereby ensuring the secure fixation of the sealing cover 7.

[0050] The method of using the high-power power supply oil cooling and heat dissipation structure of the present invention is as follows:

[0051] First, pass the inflow and outflow pipelines of the oil-cooling medium through the reinforcement cylinder 71 and connect them to the joint 3. Then slide the sealing cover 7 into the slide groove 602 and fix the sealing cover 7 by the engagement of the hook 73 and the groove 601. Finally, twist the reinforcement cylinder 71 so that the reinforcement cylinder 71 can support and fix the joint 3 and the cooling medium pipeline outside the joint 3. When the oil-cooling medium flows into the joint 3, it first enters the inflow channel 21 and flows to the outflow channel 22 through multiple heat dissipation channels 23, thereby flowing from another joint 3 to the outflow pipeline of the oil-cooling medium, taking away the heat in the heat dissipation cover 1.

[0052] 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 scope of protection of the present invention.
