Abstract

The invention discloses a lithium battery heat dissipation device which comprises a shell, a lithium battery, a condensation pipe, a dust removal device, a reset spring, a driving device and an air cooling mechanism are arranged in the shell, the lithium battery is arranged in the center of the bottom of the inner wall of the shell, and the condensation pipe is fixed to the bottom of the inner wall of the shell and is close to the end of the lithium battery. The dust removal device is arranged on the surface of the condensation pipe, the reset spring is fixed between the surface of the dust removal device and the two corresponding sides of the interior of the shell, the driving device is arranged in the position, close to the condensation pipe, of the interior of the shell, and the air cooling mechanism is fixed in the shell and close to one side of the condensation pipe. The invention relates to the technical field of lithium batteries. According to the lithium battery heat dissipation device, the purpose of self-cleaning is achieved, rapid heat dissipation can be conducted on the lithium battery, meanwhile, self-cleaning is conducted on dust adhering to the heat dissipater, the heat dissipation efficiency can be improved, overheating of the lithium battery is avoided, the service life is prolonged, and the use performance is improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a heat sink for lithium batteries. Background technique [0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution, so this battery is also called a lithium metal battery. Unlike other batteries, Li-ion batteries have the characteristics of high charge density, long life and high unit cost. According to different structural designs and electrode materials, lithium batteries can generate voltages from 1.5V to 3.7V. With the development of science and technology, lithium batteries have now become the mainstream battery. There are many types of lithium batteries and their sizes vary. Many large lithium batteries used by enterprises often need to be installed on the roof of the factory building. Weather requires cooling of large lithium batteries. [0003] At present, the...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a lithium battery cooling device, which solves the problem that the existing lithium battery cooling device has too simple structure, poor heat dissipation effect, and in some areas with relatively large dust, the radiator is easy to stick. Dust will further affect the heat dissipation effect and easily cause the lithium battery to overheat, resulting in damage to the lithium battery. The service life of the lithium battery will be seriously affected and the performance of the lithium battery will be reduced.
