Brief description of the drawings
Fig. 1 is battery schematic diagram.
Specific embodiment
Reference：10 first housings；11 first lids；20 second housings；21 second lids；30 hard pipelines；31 radiation airs
Fan；11.1 air admission holes；11.2 ventholes；11.3 first baffles；11.4 second baffles；22.1 heat-conducting blocks；22.2 radiating fins；22
It is raised；23 compression springs.
A kind of high efficiency and heat radiation lithium titanate battery, including the first housing 10, the first lid 11, the second housing 20, the second lid 21, just
Pole plate 1, negative plate 2, barrier film, electrolyte, positive terminal, negative terminal and multiple radiating parts；The second shell body is located at the first housing
Interior, the positive terminal 1 and negative terminal 2 both pass through the first lid, and the second hull outside wall has multiple raised 22, the radiating
Portion includes heat-conducting block 22.1 and the radiating fin 22.2 being connected with heat-conducting block 22.1, and the radiating fin 22.2 passes through described first
The side wall of housing, the heat-conducting block has the groove engaged with the projection, is cased with being located at the first housing on the radiating fin
Compression spring 23 and heat-conducting block between；There is hard pipeline 30, institute between second housing bottom and the first housing bottom
Stating has radiator fan 31 in hard pipeline, described first covers with air admission hole 11.1 and venthole 12.1.The radiating fin
The rectangular cross-section of piece 22.2, first housing sidewall has the rectangular opening passed through by the radiating fin of rectangle.It is described
The rectangular in cross-section of hard pipeline.The quantity of the radiating part is more than or equal to 6.First lid is fixed with by first support
First baffle above air admission hole, first lid is fixed with the second gear above venthole by second support
Plate.The first baffle and second baffle are circular baffle plate.Described second covers with burst disk.
Battery of the invention, by heat-sink unit and radiator fan, it is possible to achieve double-radiation function, the heat of the second housing is passed
