Material, width are 80~150mm, and with a thickness of 8~20mm, wall thickness is 0.5~4mm.
Heat conductive insulating coating 2 is a kind of higher insulating materials of thermal coefficient, is set at least one of metal master 1
On surface, it is preferable that heat conductive insulating coating is set on the working face of metal master 1.In addition, heat conductive insulating coating 2 is thermally conductive
Coefficient is greater than 1.5W/mK, with a thickness of 0.3~2mm.Further, the pressure resistance of insulating of heat conductive insulating coating 2 meets AC > 2400V,
Do not puncture when DC > 3400V, not arcing.
Further, referring in particular to Fig. 2, liquid cooling plate two sides are provided with installation base 4, liquid cooling plate by installation base 4 with
Lithium battery mould group 6 connects, and specifically, liquid cooling plate is installed in lithium battery mould group 6, heat conductive insulating coating 2 is allowed to connect with tab
Plate 5 comes into full contact with, and compresses installation base 4 with pressing device, is fixedly secured liquid cooling plate in lithium battery mould group 6.
Further, lithium battery generates heat, and heat passes to tab series board 5 by lithium battery pole ear, then is applied by heat conductive insulating
Layer 2 imports metal master 1.At this point, the cryogenic liquid in air-conditioning enters liquid cooling plate runner 3 by liquid cooling pipe, heat is taken away, then
It is secondary to be flowed back into air-conditioning by liquid cooling pipe, complete a heat dissipation circulation.Above-mentioned heat dissipation circulation is so repeated, lithium battery is constantly taken away
The heat that mould group 6 generates.
It has been provided above to the specific descriptions of the utility model for being illustrated and illustrating.But do not really want exhaustion or
The utility model is limited to disclosed precise forms by person.According to above teaching, it can be achieved that many modifications and variations.Above-mentioned implementation
Example is selected for most preferably explaining the principles of the present invention and its practical application, so that those skilled in the art can
The utility model is most preferably utilized with different embodiments and using the different modifications for being suitable for specific desired use.This is practical new
The range of type will be defined by the appended claims.
