Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery modules, in particular to a battery with a rapid heat dissipation function. Background Art

[0002] Lithium batteries are batteries with metallic lithium as the negative electrode, also known as lithium metal batteries. It is worth noting that according to the different battery configurations, lithium batteries are divided into primary batteries and secondary batteries. Early lithium batteries were primary batteries, but because the chemical properties of metallic lithium are very active, their processing, storage, and use have very high environmental requirements. Therefore, lithium batteries have not been widely used after their invention. With the development of microelectronics technology at the end of the 20th century, the number of miniaturized devices has increased, and higher requirements have been placed on power sources. Lithium batteries have entered a large-scale practical stage. At present, the most common lithium battery structure for consumers is to use metallic lithium as the negative electrode, manganese dioxide as the positive electrode, and lithium salt dissolved in an organic solvent as the electrolyte; during the installation and use of commonly used lithium battery modules, the heat dissipation effect itself is not ideal, and the heat inside the module cannot be dissipated in time, which will cause damage to the lithium battery components, and dust is easily accumulated inside.

[0003] According to the existing patent (Announcement No.: CN214013022U), a lithium battery module with a rapid heat dissipation function includes a bottom plate, a connection frame is installed at the top of the bottom plate, a first connection seat is arranged at the bottom of the inner wall of the connection frame, an exhaust fan is arranged on the right side of the connection frame, a suction fan is arranged on the left side of the connection frame, a cover plate is arranged at the top of the connection frame, a second connection seat is arranged at the bottom of the cover plate, a filter is arranged on the outside of the suction fan, a connecting rod is installed at the end of the filter, and blocks are arranged at both ends of the connecting rod.

[0004] However, the above technical solution still has certain shortcomings. First, when the device uses a cover to close the connection frame, multiple bolts are required to fix the four corners respectively. Disassembly and installation are too troublesome, which affects efficiency. Secondly, the device only uses exhaust fans and suction fans to dissipate heat inside the device, and the cooling effect on the battery module may not be ideal. For this reason, a battery with rapid heat dissipation function is proposed. Utility Model Content
