A high-efficiency heat dissipation battery pack structure

Abstract

The invention discloses a high-efficiency heat dissipation battery pack structure, comprising a battery box, a thermally conductive silica gel plate is mounted on the inner bottom of the battery box, a battery pack is mounted on the thermally conductive silica gel plate, and an inner wall of the battery box is fixedly connected with a Two brackets, a rotating rod that is rotatably connected to the two brackets runs through the two brackets, and a temperature-controlled rotation mechanism is installed on the rotating rod. Four disc-shaped heat exchange tubes communicated with the rotating tube are installed, a pumping heat exchange mechanism is installed between the two ends of the rotating tube and the battery box, and a mounting frame is fixedly connected to the bottom of the battery box. The invention can not only realize effective and efficient heat dissipation of the battery pack, but also can realize the temperature control of the operation of the water pump, reduce the loss of electric energy of the battery pack, and at the same time, can realize the air circulation in the battery box, and further improve the battery pack in the battery pack. heat dissipation between.

Description

technical field [0001] The invention relates to the technical field of battery pack structures, in particular to a battery pack structure with high heat dissipation. Background technique [0002] At present, lead-acid batteries are mostly used in energy storage batteries. Lead-acid batteries have the disadvantages of large volume, low energy density ratio, low cycle times, and no environmental protection. Now lithium battery energy storage is gradually accepted by the market; with the development of industry, lithium batteries There will be more and more application scenarios, such as emergency power supply, 5G communication, home energy storage, etc.; the existing modular cylindrical cells adopt a layered structure, which has the advantages of simple structure and safety. [0003] However, the current lithium battery and the matching box of the lithium battery have certain shortcomings. For example, the module structure of the battery pack is a stack structure, which has po...

Problems solved by technology

[0002] At present, lead-acid batteries are mostly used as energy storage batteries. Lead-acid batteries have disadvantages such as large volume, low energy density ratio, less cycle times, and no environmental protection. Lithium battery energy storage is gradually accepted by the market; with the development of industry, lithium batteries There will be more and more application scenarios, such as emergency power supply, 5G communication, home energy storage, etc.; the existing modular cylindrical cells adopt a layered structure, which has the advantages of simple structure and safety

[0003] However, the current lithium battery and the matching box of the lithium battery have certain deficiencies. For example, the module structure of the battery pack is a stacked structure, and the heat dissipation capability is poor. , Turning on the water-cooling structure in the case of unnecessary heat dissipation will increase the loss of the battery. At the same time, the heating structure that maintains the operating temperature of the battery must also work, thereby greatly increasing the loss of the battery
