It is highly preferred that in the present embodiment, three settings that extend sideways adjacent along housing 10 of housing heat pipe 104.Such as Fig. 8
Shown in Fig. 9, including two sides and a bottom surface.
In the present embodiment, a kind of battery modules are additionally provided, including some cells and for for monomer electricity
The radiator structure 50 of pond radiating, wherein, some cells are the battery that the present embodiment provides, and radiator structure 50 is arranged on housing
On the side that housing heat pipe 104 is accommodated on 10.
Specifically, some cells can be connected in series with each other, battery pack is formed.In the present embodiment, radiator structure 50
It is connected with the heat conduction of housing heat pipe 104, the meaning to be expressed herein is that can be carried out between radiator structure 50 and housing heat pipe 104
Heat transfer, set using fitting is neighbouring in the present embodiment, and be provided between radiator structure 50 and housing heat pipe 104
Heat-conducting layer 60.
In order to improve the heat transfer speed between radiator structure 50 and housing heat pipe 104, in the present embodiment, in radiator structure
Heat-conducting layer 60 is provided between 50 and housing heat pipe 104, can effectively and rapidly by the heat transfer on housing heat pipe 104 extremely
Radiator structure 50, spread out by radiator structure 50.As shown in Fig. 2, Fig. 3 or Fig. 7, the heat-conducting layer 60 is to be covered in radiator structure
Heat-conducting layer 60 on 50.Led as shown in figure 9, the heat-conducting layer 60 shown in the figure is the sheet for being arranged on battery modules bottom
Thermosphere 60.
In the present embodiment, in order to improve the heat transference efficiency of radiator structure 50, radiator structure 50 can select flat
Heat radiating flat tube.As shown in fig. 7, heat radiating flat tube is provided at both ends with entrance 501 and pipe outlet 502, the radiating is flat
Pipe includes heat radiating flat tube shell 503 and runner 504.
In the present embodiment, by the cooperation between radiator structure 50 and housing heat pipe 104, when improving battery and occurring abnormal
Radiating efficiency, the security that uses of increase battery modules.
As shown in fig. 7, two housing heat pipes 104 have been arranged side by side on a side of housing 10, battery modules are assembled into
When, the heat radiating flat tube that outside is coated with heat-conducting layer 60 is connected with the heat conduction of housing heat pipe 104.
As shown in figure 9,10 3 sides of housing carry housing heat pipe 104, during assembling, bottom shell heat pipe 104 passes through piece
Shape heat-conducting layer 60 is connected with the heat conduction of radiator structure 50, and positioned at the housing heat pipe 104 of two vertical direction sides, by other portions of battery
The heat transfer of position then is shed by radiator structure 50 to the housing heat pipe 104 of bottom.
Understand that the utility model is to have above-described good characteristic in summary, be able to make it using upper, enhancement
The efficiency that does not have in conventional art and there is practicality, turn into the product of a great practical value.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification, equivalent substitution or improvement made within the thought and principle of utility model etc., should be included in the utility model
Protection domain within.
