Description

technical field [0001] The invention relates to a heat conduction module of a lithium battery, especially a lithium battery unit arranged in a heat conduction body to dissipate heat from the lithium battery unit. Background technique [0002] As the electric vehicle market gradually matures, the demand for lithium batteries has increased significantly. The lithium battery module of the prior art electric vehicle is mainly provided with a plurality of lithium battery cells connected in parallel or in series inside a casing, and a positive electrode conductive electrode post and a negative electrode conductive electrode post are provided outside the casing, so as to connect the conductive electrodes respectively. After the terminals, a large working current or voltage is output, and when multiple sets of lithium battery modules are assembled in a lithium battery box, it can have sufficient electric capacity to supply the power required for driving the vehicle.

Problems solved by technology

However, due to the rapid accumulation of heat in the box during the operation of the lithium battery module, it is even more difficult for the heat emitted by the lithium battery cells in the central area of ​​the box to dissipate quickly. Once a problem occurs with the lithium battery cells, it will spread to the Lithium battery module short circuit or other fault conditions caused by other lithium battery cells

[0004] Most of the heat dissipation technologies used in the market for electric vehicle lithium battery boxes are water-cooled or air-cooled. However, water-cooled heat dissipation equipment is expensive and takes up a lot of space, while air-cooled heat dissipation equipment has dead spots for heat dissipation, resulting in uneven heat dissipation. situation, and these two heat dissipation technologies will consume the power stored in the lithium battery module during operation, which is not practical for electric vehicles
