Lithium battery device with heat dissipation function for lithium battery

Abstract

The invention discloses a lithium battery device with a heat dissipation function for a lithium battery. The device comprises an outer shell, a top cover and an inner shell, an air outlet bin and an air inlet bin are symmetrically arranged on the front surface of the outer shell, an exhaust fan is arranged in the air outlet bin, a suction fan is arranged in the air inlet bin, and a positive electrode connector and a negative electrode connector are symmetrically arranged on the top cover; and the positive electrode connector and the negative electrode connector are provided with wire insertionholes, the top cover is provided with an electric quantity display screen in an embedded mode, a positive pole column and a negative pole column are arranged at the upper end of the inner shell, a heat pipe is arranged between the positive pole column and the negative pole column, an evaporation section and a condensation section are arranged in the heat pipe, the heat pipe is filled with alcohol, and the heat dissipation cavity is filled with heat conduction oil. Supporting plates are arranged at bottoms of a heat dissipation cavity and the inner shell, and a heat dissipation plate is arranged on a back surface of the outer shell. By arranging the air outlet bin, the air inlet bin, the heat pipe, the heat dissipation cavity and the heat dissipation plate, the interior of the battery is effectively cooled, by arranging the electric quantity display screen, the electric quantity of the lithium battery is displayed in real time, and a user can conveniently control the electric quantityof the lithium battery and charge the lithium battery in advance.

Description

technical field [0001] The invention relates to the technical field of lithium battery casings, in particular to a lithium battery device with heat dissipation function for lithium batteries. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream. [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 ...

AI Technical Summary

Problems solved by technology

There are following problems in the automobile lithium battery casing of the prior art: the structure of the lithium battery casing of the current automobile is mostly complex and cumbersome, and the heat dissipation effect is not ideal, and most of the lithium battery heat dissipation is water-cooled heat dissipation, which will lead to uneven heat dissipation. It directly affects the working efficiency of the lithium battery and the life of the lithium battery, resulting in large economic losses
