Description

Technical Field

[0001] The utility model relates to the technical field of energy storage liquid cooling plate equipment, in particular to an energy storage liquid cooling plate composite structure. Background Art

[0002] In battery systems, a metal radiator that is filled with indirect liquid cooling media is called a liquid cooling plate. It is generally made of a metal plate or metal tube extruded or stamped from an aluminum alloy mold and then welded together. The liquid cooling plate is designed to use the flow of cooling liquid to absorb and remove the heat generated by the battery system.

[0003] For example, the utility model patent disclosed in the publication number CN220039200U is a novel composite structure uniform temperature liquid cooling plate, comprising a plate structure, wherein the two sides of the plate structure are respectively connected to a water inlet cavity and a water outlet cavity, and a liquid cooling channel and a steam chamber structure are provided on the plate structure, wherein the liquid cooling channel is connected to the water inlet cavity and the water outlet cavity, and a plurality of support columns are provided in the steam chamber structure, and a porous medium structure is filled between any two of the support columns. The steam chamber structure can evenly distribute the heat, which is beneficial for the coolant in the liquid cooling channel to take away the heat and reduce the overall heat transfer resistance. In addition, the steam chamber structure is filled with a porous medium structure, which can further absorb heat, and its cooling effect is significant, which greatly reduces the heat transfer resistance of the liquid cooling plate.

[0004] Although the above-mentioned liquid cooling plate has certain heat absorption and heat dissipation performance, the efficiency of heat exchange between the liquid cooling cavity and the heat adsorption mechanism of the above-mentioned liquid cooling plate is insufficient, thereby reducing the efficiency of the liquid cooling plate in absorbing and dissipating heat for batteries or other electronic products. Therefore, a composite structure of an energy storage liquid cooling plate is urgently needed to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the present invention is to provide an energy storage liquid cooling plate composite structure to solve the problems raised in the above background technology.

The hollow heat exchange guide, support column and heat exchange base can effectively improve the efficiency of subsequent adsorption heat energy transfer to the heat exchange plate, and can also improve the subsequent heat exchange efficiency with the coolant inside the liquid cooling plate shell.

[0011] Preferably, the lower end surface of the heat exchange base is fixedly connected to the upper end surface of the heat exchange plate, and the heat exchange base is fixedly connected to the heat exchange plate. Multiple groups of heat exchange bases can directly absorb the heat inside the heat exchange plate, effectively improving the speed of subsequent heat conduction.

[0012] Preferably, the liquid inlet conduit is sealed and fixedly connected to the side end surface of the liquid cooling plate shell through the sealing groove. When the coolant is diverted, the coolant can enter from the liquid inlet conduit on one side and then be discharged through the liquid guide pipe on the other side of the liquid cooling plate shell, which can improve the heat exchange distance between the coolant and the heat exchange guide plate.

[0013] Preferably, the support column is sealed and fixed on the lower end surface of the liquid cooling plate shell through the fixed guide hole, and multiple sets of heat exchange guides can perform heat exchange operations with the coolant to the greatest extent inside the liquid cooling plate shell, effectively improving the efficiency of subsequent heat exchange.

In addition, the multiple sets of heat exchange guides can effectively increase the contact area with the coolant, thereby maximizing the heat exchange rate between the coolant and the heat energy inside the heat exchange guides, thereby increasing the speed of heat energy adsorption for the battery and thus improving the protection of the battery.

[0025] The heat exchange guide 41, the support column 42 and the heat exchange base 43 are integrally arranged, and the interior of the heat exchange guide 41, the support column 42 and the heat exchange base 43 are all hollow. The hollow heat exchange guide 41, the support column 42 and the heat exchange base 43 can effectively improve the efficiency of subsequent adsorption of heat energy transfer to the heat exchange plate 6, and can also improve the subsequent heat exchange efficiency with the coolant inside the liquid cooling plate shell 1.

The heat exchange base 43 is fixedly connected to the heat exchange plate 6. Multiple groups of heat exchange bases 43 can directly absorb the heat inside the heat exchange plate 6, effectively improving the speed of subsequent heat conduction.

[0027] The liquid inlet conduit 3 is sealed and fixedly connected to the side end surface of the liquid cooling plate shell 1 through the sealing groove 2. When the coolant is diverted, the coolant can enter from the liquid inlet conduit 3 on one side and then be discharged through the liquid guide pipe 5 on the other side of the liquid cooling plate shell 1, which can improve the heat exchange distance between the coolant and the heat exchange guide fin 41.

When the battery is dissipating heat, multiple sets of integrated heat exchange bases 43, support columns 42 and heat exchange guides 41 can quickly transfer the heat energy adsorbed by the heat exchange plate 6. Multiple sets of heat exchange guides 41 can quickly exchange heat energy with coolant inside the liquid cooling plate shell 1, thereby improving the heat dissipation efficiency of the battery. In addition, multiple sets of heat exchange guides 41 can effectively increase the contact area with the coolant, thereby increasing the heat exchange rate between the coolant and the internal heat energy of the heat exchange guide 41, thereby completing the heat dissipation operation of the battery.
