Description

Technical Field

[0001] The present application relates to the technical field of energy storage reactors, and in particular to a liquid cooling radiator for energy storage reactors. Background Art

[0002] With the rapid development of power electronics technology, high-power reactors play an increasingly important role in power systems. However, as the power of the reactor increases, the heat generated during its operation also increases accordingly, making the heat dissipation problem of the reactor particularly prominent.

[0003] At present, the heat dissipation of high-power reactors mainly relies on liquid cooling systems. However, due to the large number of heat-generating components in the electric controller, including copper wires, magnetic cores, and windings, the cooling medium of the ordinary liquid cooling system is affected by the complex internal structure, layout, and heat dissipation surface of the reactor during the flow process, resulting in uneven cooling effect. The heat dissipation effect is good in some areas, while other areas may have poor heat dissipation due to poor flow of cooling medium or unreasonable heat dissipation surface design. This uneven heat dissipation condition will cause uneven temperature distribution inside the reactor, affecting its electrical performance and stability. Utility Model Content

[0004] In order to achieve uniform heat dissipation of the energy storage reactor as much as possible, the present application provides a liquid cooling radiator for the energy storage reactor.

[0005] The present application provides a liquid cooling radiator for an energy storage reactor using the following technical solution:

[0006] A liquid-cooled radiator for an energy storage reactor comprises: a substrate, wherein a receiving cavity for placing a heating device is formed in the substrate, and a plurality of liquid-cooling pipes are opened on the substrate; a sealing plate, which is arranged at both ends of the substrate, and a joint is installed on the sealing plate; a cover plate, which is arranged on a side of the sealing plate away from the substrate, a liquid-cooling cavity is formed between the sealing plate and the cover plate, and the liquid-cooling cavity is connected to the liquid-cooling pipe and the joint.

[0007] By adopting the above technical solution, the liquid cooling medium first flows in through a joint, and then enters the liquid cooling cavity adjacent to the joint; then, the liquid cooling medium is divided into multiple liquid cooling pipes; after that, the liquid cooling medium converges to another liquid cooling cavity, and finally flows out from another joint. In this way, the substrate is effectively cooled, thereby ensuring that the heat-generating device can dissipate heat evenly, improving its stability and service life.

[0008] Preferably, the plurality of liquid cooling pipes on the substrate are divided into a plurality of groups, and a reflux groove is provided on the substrate corresponding to each group of the liquid cooling pipes.

[0009] By adopting the above technical solution and setting a reflux groove, the liquid cooling medium in the liquid cooling chamber can be diverted to the liquid cooling pipe as much as possible, so that the liquid cooling pipe can pass as much liquid cooling medium as possible, thereby improving the cooling effect.

[0010] Preferably, the sealing plate is provided with a through hole corresponding to the reflux groove.

[0011] By adopting the above technical solution and providing a through hole, the liquid cooling medium in the cooling cavity can enter the reflux groove.

[0012] Preferably, the base plate is provided with a first mounting groove for cooperating with screws, the sealing plate is provided with a through hole corresponding to the first mounting groove, and a mounting column is provided on the side of the sealing plate close to the cover plate, the mounting column is provided with a second mounting groove for cooperating with screws on the side close to the cover plate, and the cover plate is provided with countersunk holes corresponding to the first mounting groove and the second mounting groove.

[0013] By adopting the above technical solution, some screws start from the outer side of the sealing plate away from the substrate, pass through the countersunk holes and through holes in sequence, and are firmly installed in the first installation groove; while another part of the screws directly pass through the countersunk holes from the outer side of the sealing plate and are firmly fixed in the second groove to achieve fixed installation between the cover plate, the sealing plate and the substrate.

[0014] Preferably, the cover plate is welded to the sealing plate via a first brazing plate.

[0015] By adopting the above technical solution, the welding strength between the cover plate and the sealing plate is improved, thereby preventing the liquid cooling medium from leaking from the gap between the cover plate and the sealing plate.

[0016] Preferably, the sealing plate is welded to the base plate via a second brazing plate.

[0017] By adopting the above technical solution, the welding strength between the sealing plate and the base plate is improved, thereby preventing the liquid cooling medium from leaking from the gap between the sealing plate and the base plate.

[0018] Preferably, the liquid cooling pipe is integrally formed on the substrate by an extrusion profile process.

[0019] By adopting the above technical solution, complex machining costs can be eliminated, material costs can be effectively reduced, and production efficiency can be improved.

[0020] Preferably, the sealing plate is forged by a high-precision cold forging process.

[0021] By adopting the above technical solution, complex CNC processing is eliminated, and the cold forging one-piece molding technology is adopted. Taking the mold as the basis, the work efficiency is significantly improved, while ensuring a high yield and low processing cost, with a high cost performance.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The liquid cooling medium first enters the liquid cooling cavity near the joint through a joint, and then flows smoothly into multiple liquid cooling pipes through the through hole; then, the liquid cooling medium further flows into another liquid cooling cavity, and finally flows out from another joint. The above structure can effectively cool the substrate, thereby achieving uniform heat dissipation of the heat generating device, ensuring stable operation of the equipment and extending its service life;

[0024] 2. The use of the first brazing plate and the second brazing plate can improve the welding effect, thereby improving the overall sealing and avoiding the leakage of the liquid cooling medium to the greatest extent. BRIEF DESCRIPTION OF THE DRAWINGS

The liquid cooling medium can enter the liquid cooling cavity 6 adjacent to the joint 7 through one of the joints 7, and then enter the liquid cooling pipe 3, and flow out from the other joint 7 through another liquid cooling cavity 6, so that the heat generated by the components can be taken away by the circulation of the liquid cooling medium to achieve cooling.

The bottom plate 11 and the side plates 12 are rectangular plates as a whole, and the length direction of the bottom plate 11 is parallel to the length direction of the side plates 12. The two side plates 12 are arranged on both sides of the length direction of the bottom plate 11, and the length direction surface of the side plate 12 is perpendicular to the length direction surface of the bottom plate 11. In this embodiment, the liquid cooling pipe 3 is integrally formed by an extrusion profile process, thereby eliminating the complex machining cost, while also reducing the material cost and improving the production efficiency.

[0033] On this basis, the multiple liquid cooling pipes 3 are divided into multiple groups, and the multiple groups of liquid cooling pipes 3 are evenly opened on the base plate 1, so that the heat-generating device in the accommodating cavity 2 can achieve uniform heat dissipation. In this embodiment, the liquid cooling pipes 3 on the bottom plate 11 and near the bottom plate 11 are grouped in three, and the liquid cooling pipes 3 in each group are evenly distributed, while the liquid cooling pipes 3 on the side plate 12 are grouped in two.
