Lithium battery with inside structure matched with heat pipe heat radiation mode

Abstract

The invention discloses a lithium battery with an inside structure matched with a heat pipe heat radiation mode. The lithium battery comprises a battery box and a storage box, wherein the battery box is connected with the storage box through a pipeline. The lithium battery is characterized in that a heat conduction medium is arranged in the storage box; in addition, a heat exchanger is arranged on the storage box; the heated end of the heat exchanger is inserted and arranged in the heat conduction medium in the storage box; the cooling end of the heat exchanger is directly exposed in the external air. The inside heat radiation medium and structure in a battery pack are effectively matched for performing temperature reduction treatment; through the arrangement of an external heat exchanger, the installation and the maintenance are easy; the heat pipe heat resistance is small; the heat radiation effect is good; the heat transfer can be realized without the direct contact of the cold side and the hot side of the heat exchanger; in addition, the cooling end heat exchange is accelerated by using the vehicle self convection wind; the use safety of the battery pack is improved; the service life of the battery pack is prolonged; the self starting is realized in the whole process; the manual control is not needed; convenience, sensitivity and high speed are realized.

Description

technical field [0001] The invention relates to lithium battery technology, in particular to a lithium battery with an internal structure matched with a heat pipe heat dissipation method. Background technique [0002] Compared with traditional fuel vehicles, electric vehicles have better controllability, stability and safety. Lithium batteries are the energy storage components of pure electric vehicles, but when the vehicle is running normally, the lithium battery power battery pack will generate a lot of heat along with charging and discharging. If the heat is not transferred to the outside through the heat dissipation channel in time, it will directly reduce the battery life. Performance, cycle life and safety. In the prior art, the heat dissipation treatment of lithium batteries is mostly on the internal structure of the battery. For example, the patent publication number is CN105703034A, a new heat dissipation system for lithium battery modules of electric vehicles, inc...
