Heat dissipation tube sleeve structure for vehicle battery

Abstract

The invention discloses a heat dissipation tube sleeve structure for a vehicle battery. The heat dissipation tube sleeve structure comprises a reinforcement sleeve, a heat conduction sleeve structurecoaxially fixed inside the reinforcement sleeve, and a heat absorption sleeve coaxially fixed inside the heat conduction sleeve; the heat conduction sleeve structure comprises a heat conduction sleeve, and a heat conduction sheet and a heat dissipation sheet fixed on the outer circumferential surface of the heat conduction sleeve and arranged along the length direction of the heat conduction sleeve, the heat conduction sheet passes at least partially through the reinforcing sleeve and extends to the outside of the reinforcing sleeve, and the heat conduction sheet outside the reinforcing sleeveis fixed with the heat dissipation sheet; the heat absorbing sleeve is made of composite phase change material, the heat conduction sleeve structure is made of heat conduction material, and the reinforcing sleeve is made of hard plastic. The invention solves the problem that the ordinary wrapping material is prone to aging and cracking caused by that the research on the heat dissipation of the power battery mainly focuses on the casing structure of the battery module, but ignores the heat dissipation problem of the power battery connection line at present, resulting in the increase of the battery temperature within the module which inevitably affects the temperature rise of the connection line.

Description

technical field [0001] The invention relates to an automobile battery accessory, in particular to a heat dissipation pipe sleeve structure for an automobile battery. Background technique [0002] With the rapid and vigorous development of the economy, global energy shortages and environmental pollution have become increasingly prominent, energy conservation and emission reduction are gradually attracting the attention of the world, and the development of electric vehicles has also become a major trend. , especially when starting to climb a slope or suddenly accelerating, the discharge current increases instantaneously, thereby generating a large amount of heat, which can make the battery temperature inside the module reach 100°C, and it will be close to 200°C in the case of overcharging. At present, the heat dissipation research of the power battery mainly focuses on the shell structure of the battery module, but ignores the heat dissipation problem of the connection line of...
