A high-efficiency local cooling device and cooling method for lithium batteries

Abstract

The invention provides a lithium battery high-efficiency local cooling device and a cooling method, which belong to the technical field of lithium battery cooling equipment. The lithium battery high-efficiency local cooling device includes a battery box, and the upper end of the battery box is provided with a lithium battery slot and four slots. The four slots are respectively located at the four corners of the upper end of the battery box. Plug blocks are movably inserted in the four slots. The upper ends of the four plug blocks are fixed with battery covers. A set of fixing mechanisms are provided in the four slots. The fixing mechanisms are all connected with the inserts to fix the battery cover on the upper end of the battery box. Two lithium batteries are installed in the lithium battery slot, the lower inner wall of the lithium battery slot is fixed with a water cooling tube, and the front end of the battery box is fixed with a water tank. , the water-cooled tube runs through the front end of the battery box and communicates with the water tank, and the front and rear inner walls of the lithium battery tank are fixed with support plates; damage, greatly increasing the service life of lithium batteries.

Description

technical field [0001] The invention belongs to the technical field of lithium battery cooling equipment, and in particular relates to a high-efficiency local cooling device and a cooling method for a lithium battery. 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] During the use of lithium batteries, a large amount of heat will be generated during operation, which will increase the temperature of the loc...
