Embodiment Construction

[0034] The present invention will be further described now in conjunction with accompanying drawing. These drawings are simplified schematic diagrams only to illustrate the basic structure of the present invention in a schematic way, so they only show the components relevant to the present invention.

[0035] like Figure 1 to Figure 7 As shown, a battery cooling device includes: a battery 1 having a casing, and an insulating layer is provided on the outer surface of the casing to form an outer insulating casing 2 . The casing can be made of a metal casing, a non-metal casing or a composite material, for example, an aluminum-plastic film can be used for the composite material.

[0036] The outer shell 4 is used to accommodate the coolant. The outer shell 4 is composed of an upper shell 41 and a lower shell 42. The upper shell 41 and the lower shell 42 form a shell cavity. The outer shell 4 is provided with a liquid inlet and an outlet. The liquid port can also circulate air ...

Abstract

The invention relates to a battery cooling device, which comprises batteries, an outer sleeve shell and a mainboard, wherein each battery comprises a housing; an insulating layer is arranged on the outer surface of each housing to form an outer insulating housing; the outer sleeve shell is used for accommodating a cooling liquid; the outer sleeve shell comprises an upper shell and a lower shell; a sleeve shell cavity is enclosed by the upper shell and the lower shell; the outer sleeve shell is provided with a liquid inlet and a liquid outlet; the mainboard is used for assembling the batteries and is provided with a plurality of mounting holes; the upper parts of the batteries and the mainboard are arranged in a sealing manner; and the lower parts of the outer insulating housings are arranged in the sleeve shell cavity of the outer sleeve shell. The outer insulating housings provided by the invention are soaked into the cooling liquid for cooling, so that the target of keeping the longitudinal temperature of each battery uniform and the temperature among the batteries uniform is achieved.

Description

[0001] The patent application for the present invention is a divisional application. The application number of the original case is CN201410741687.4, the application date is December 08, 2014, and the title of the invention is: a battery cooling device. technical field [0002] The invention relates to the field of heat exchange equipment for power storage batteries of electric vehicles, gasoline-electric hybrid vehicles, or fuel cell vehicles, and in particular to a battery cooling device. Background technique [0003] As the power source of electric vehicles, power batteries are a key part of improving vehicle performance and reducing costs. Their temperature characteristics directly affect the performance, life and durability of vehicles. Lithium-ion batteries have large specific energy, long cycle life, and Low efficiency, wide allowable operating temperature range, good low temperature effect and other advantages are currently the preferred power battery. Therefore, i...
