Description

Technical Field

[0001] This utility model relates to the field of energy storage battery technology, specifically to a heat dissipation structure for energy storage batteries. Background Technology

[0002] With the rapid development of electric vehicles, renewable energy and other fields, the application of energy storage batteries is becoming more and more widespread. However, batteries generate a lot of heat during operation. If heat cannot be dissipated in a timely and effective manner, the battery temperature will rise, affecting battery performance, lifespan and even causing safety problems.

[0003] Existing energy storage battery heat dissipation technologies mainly include three categories: air cooling, liquid cooling, and phase change material cooling. However, these methods lack an efficient heat dissipation structure that combines liquid cooling and air cooling. Using air cooling, liquid cooling, or phase change material cooling alone cannot remove the heat generated by the battery more quickly, thus affecting the heat dissipation area and heat exchange efficiency.

[0004] Therefore, it is necessary to design a heat dissipation structure for energy storage batteries to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation structure for energy storage batteries, which improves heat dissipation efficiency, increases heat dissipation area and heat exchange efficiency through the synergistic effect of liquid cooling and air cooling, and quickly removes the heat generated by the battery, thereby improving the heat dissipation performance of the energy storage battery and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat dissipation structure for an energy storage battery includes a housing, an inlet pipe fixedly connected to one side of the housing, an outlet pipe fixedly connected to the other side of the housing, a sealing seat provided on the inner wall of the housing, a battery module heat exchange assembly disposed inside the housing, a heat dissipation assembly disposed on the upper surface of the housing, and the heat dissipation assembly including a sealing top cover, the bottom end of the sealing top cover being movably snapped onto the top of the housing, and a connecting bolt threaded between the sealing top cover and the upper surface of the housing.

[0008] As a preferred embodiment of this utility model, the battery module heat exchange assembly includes a base and a sealing top seat. The lower surface of the base is attached to the bottom of the inner wall of the outer shell, and a battery mounting cylinder is fixedly connected to the upper surface of the base. The lower surface of the sealing top seat is movably engaged with the interior of the sealing seat, and a guide plate is fixedly connected to the lower surface of the sealing top seat. An installation hole is provided on the upper surface of the sealing top seat.

[0009] As a preferred embodiment of this utility model, the battery mounting cylinder has a hexagonal cylindrical structure, the mounting hole is connected to the interior of the battery mounting cylinder, and multiple battery mounting cylinders are evenly distributed, with each of the multiple battery mounting cylinders corresponding to the other.

[0010] As a preferred embodiment of this utility model, the mounting hole has a hexagonal through-hole structure, and the inner wall of the mounting hole is adapted to the size of the outer wall of the end of the battery mounting cylinder.

[0011] As a preferred embodiment of this utility model, multiple guide plates are evenly distributed, and guide grooves are formed on the sides of the multiple guide plates.

[0012] As a preferred embodiment of this utility model, a heat dissipation channel is fixedly connected to the top of the sealing top cover, heat dissipation fins are fixedly connected to both sides of the heat dissipation channel, a mounting bracket is fixedly connected to the top of the sealing top cover, and a cooling fan is fixedly connected to the top of the sealing top cover.

[0013] As a preferred embodiment of this utility model, a heat dissipation groove is provided inside the heat dissipation channel, penetrating the bottom of the sealed top cover.

[0014] As a preferred embodiment of this utility model, the heat dissipation fins are provided in multiple equidistant distributions along the length of the heat dissipation channel, and the interior of the multiple heat dissipation fins is connected to the interior of the heat dissipation channel.

[0015] Beneficial Effects: Addressing the issue that existing energy storage batteries lack a highly efficient heat dissipation structure that combines liquid and air cooling, hindering the rapid removal of heat generated by the battery and impacting heat dissipation area and efficiency, this invention solves the problem. By incorporating a battery module heat exchange component with inlet and outlet pipes connected to a liquid cooling system on the exterior, multiple independently mountable hexagonal cylindrical battery mounting cylinders exchange heat through guide channels on a guide plate, achieving rapid cooling. This increases the heat dissipation area and efficiency, enabling faster removal of battery heat and improving overall battery cooling performance. Furthermore, the heat dissipation component utilizes a heat dissipation channel penetrating the sealed top cover to connect multiple heat dissipation fins, equipped with a cooling fan. This effectively guides and efficiently dissipates heat emitted from the mounting holes inside the battery mounting cylinders, significantly reducing battery temperature. The overall structure is simple yet highly efficient, combining liquid and air cooling, increasing heat dissipation area and efficiency, and rapidly removing battery heat, thus improving overall battery cooling performance. This design is highly practical. Attached Figure Description
