High-heat-dissipation lithium battery cell battery pack

Abstract

The invention discloses a high-heat-dissipation lithium battery cell battery pack in the technical field of lithium batteries. The battery pack comprises a shell, a vent hole is formed in the left side surface of the shell, a cavity is formed in the left end of the top of the shell, a first partition plate is arranged on the right side of the cavity, and a heat dissipation device is arranged in the cavity and comprises a water tank; and a cooling pipeline is connected to the left side of the top of the water tank, a thermostat is arranged at the right end of the cooling pipeline, a circulatingpump is arranged above the thermostat, a water temperature sensor is arranged above the circulating pump, a cold-heat exchanger is arranged on the right side of the water temperature sensor, and a cooler is arranged below the cold-heat exchanger. The cooler is connected with the right side of the top of the water tank through a cooling pipeline, a plurality of mounting grooves are formed in the top of the shell, lithium battery cells are arranged in the mounting grooves, second partition plates are arranged between the mounting grooves, the second partition plates transmit heat generated by the lithium battery cells to the cooling pipeline, and the heat generated by the lithium battery cells is dissipated through the cooling pipeline; and the service life of the lithium battery cells is prolonged.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a strong heat dissipation lithium battery pack. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental and technical requirements, so lithium batteries have not been practically used. [0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, are superior to lithium-ion batteries in terms of safety, specific capacity, self-discharge rate and performance-price ratio. [0004] Since entering the 21s...

AI Technical Summary

Problems solved by technology

[0004] Since entering the 21st century, with the rapid development of science and technology, lithium batteries have become the mainstream. Now most of the use of lithium batteries is to combine multiple lithium batteries, so that the heat emitted by lithium batteries during the working process cannot be dissipated in time. Go out, reduce the service life of the lithium battery
