Technical field
The utility model relates to a kind of housing of lithium ion battery, especially relates to a kind of housing for automobile lithium ion battery, belongs to parts in automobile lithium ion battery.
Background technology
Housing for automobile lithium ion battery commonly used comprises upper cover and shell at present, be provided with a battery core installation cavity in shell, upper cover directly is fixed on shell, and the structural design of this shells is reasonable not, and heat dispersion is poor, due to automobile batteries in use, discharging current is large, and the temperature of generation is high, and a large amount of heats is difficult to distribute, thereby greatly affected the overall performance of automobile lithium ion battery, shortened the useful life of automobile lithium ion battery.
The utility model content
The purpose of this utility model is to overcome above shortcomings in prior art, and a kind of reasonable in design is provided, and perfect heat-dissipating is conducive to promote the housing for automobile lithium ion battery of automobile lithium ion battery overall performance.
The technical scheme in the invention for solving the above technical problem is: should comprise upper cover and shell for the housing of automobile lithium ion battery, be provided with the battery core installation cavity in described shell, described upper cover is fixed on shell, its design feature is: the wall of described shell is provided with the ordered series of numbers louvre, louvre is through-hole structure, the inwall that is provided with the wall of louvre in this shell is provided with several thermal troughs, a thermal trough is corresponding with a row louvre, and an end of louvre is arranged in corresponding thermal trough.
As preferably, shell described in the utility model is rectangular structure.
As preferably, the utility model louvre be shaped as circular configuration, the diameter of louvre and the width of thermal trough equate.
As preferably, the utility model thermal trough be shaped as rectangular structure.
As preferably, upper cover described in the utility model is weldingly fixed on shell.Firmness and intensity between housing have effectively been guaranteed thus; Generally, upper cover adopts ultrasonic bonding to be fixed on shell, has more guaranteed firmness and intensity between housing.
As preferably, the upper end of thermal trough described in the utility model flushes with the top of shell.
As preferably, in the shell of rectangular structure described in the utility model, two relative walls are provided with louvre.
The utility model compared with prior art, has the following advantages and effect: simple in structure, reasonable in design, perfect heat-dissipating, be conducive to promote the automobile lithium ion battery overall performance.Because the automobile batteries discharging current is large, temperature is high, has adopted the porous design, is convenient to heat radiation.A thermal trough is corresponding with a row louvre, one end of louvre is arranged in corresponding thermal trough, louvre has formed the structure that outer imperial palace is little, and endoporus is lower than the surface of housing inner chamber, the design of employing thermal trough, make the injection moulding burr of louvre effectively to avoid, can directly not damage battery core in housing.
