Heat dissipating plate fixation structure

Abstract

The present invention discloses a heat dissipating plate fixation structure, which comprises two opposite first clamping parts, two second clamping parts and two pressing plates, wherein the same side of a bottom plate extends to form the two opposite first clamping parts, the two first clamping parts are positioned between the two second clamping parts, the first clamping part comprises a first fixation end connected to the bottom plate and a first elastic end away from the bottom plate, the second clamping part comprises a second fixation end connected to the bottom plate and a second elastic end away from the bottom plate, the two pressing plates are placed opposite to each other and are positioned between the two first clamping parts, one end of the pressing plate bears against the first elastic end of the corresponding first clamping part, the other end of the pressing plate is fixed on the second elastic end of the corresponding second clamping part, the fixation position of one pressing plate and the second clamping part is provided with a pair of clamping sheets, and the fixation position of the other pressing plate and the second clamping part is provided with a pair of clamping surfaces matched with the clamping sheets. The heat dissipating plate fixation structure is convenient to install, and can improve the adhesion effect of the flat plate heat pipe and the cold plate.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of heat dissipation structures of battery modules, in particular to a heat dissipation plate fixing structure. [0003] 【Background technique】 [0004] At present, vehicle power batteries have been widely used in new energy electric vehicles. With the development of society, new energy vehicles have higher and higher requirements for high-rate charging and discharging of power batteries, resulting in more severe heat dissipation problems caused by high-rate charging and discharging. The most commonly used heat dissipation method is a heat dissipation structure made of a flat heat pipe and a cold plate. This structure has good heat conduction and heat dissipation performance, but its fixing method has the following disadvantages: 1. Since a pressure plate is used between the flat heat pipe and the cold plate in the form of screws Locking, cumbersome installation; 2. It is necessary to open screw holes on the c...

The most commonly used heat dissipation method is a heat dissipation structure made of a flat heat pipe and a cold plate. This structure has good heat conduction and heat dissipation performance, but its fixing method has the following disadvantages: 1. Since a pressure plate is used between the flat heat pipe and the cold plate in the form of screws Locking, cumbersome installation; 2. It is necessary to open screw holes on the cold plate, which has a great impact on the strength; 3. The cold plate and the flat heat pipe are locked by the screw-fixed pressure plate. When the pressure plate is deformed, the water-cooled plate and the flat heat pipe are attached The quality has a great influence, which directly affects the heat transfer effect
