Embodiment 1

[0022] like Figure 1-2 As shown, a liquid immersion cooling type automotive power battery pack provided in this embodiment includes a casing 1 with an open upper end, a cover body 2 sealingly connected with the upper opening of the casing 1, and a cover for connecting with the outside The connecting terminal for circuit connection, the cover body 2 is provided with a hollow chamber, the housing 1 is provided with a battery pack, insulating cooling liquid and a pump 6, the connecting terminal is electrically connected with the battery pack, and the The insulating cooling liquid fills the inner space of the housing 1, the pump 6 is connected to the hollow chamber of the cover 2 through the pipeline 5, and the lower surface of the cover 2 is provided with a The interior of the hollow chamber with the liquid outlet. Specifically, the connecting terminal 9 is used as the power output terminal to supply power to the automobile. A large amount of heat will be generated during the c...

Embodiment 2

[0030] like image 3 As shown in the figure, a liquid immersion cooling type automotive power battery pack provided in this embodiment, the difference between this embodiment and Embodiment 1 is that the heat dissipation fins 11 and the heat dissipation fan 12 on the cover body 2 are cancelled. The spray-cooled vehicle power battery pack also includes an air-cooled radiator 4 , the pipeline 5 includes a heat-dissipating section 3 , and the heat-dissipating section 3 is a coiled tubular structure, and the heat-dissipating section 3 and the air-cooled radiator 4 Connected to and located in the air-cooled radiator 4, specifically, when the pump 6 sucks the insulating cooling liquid in the housing 1 and flows to the heat-dissipating section 3, the air-cooled radiator 4 flows through the heat-dissipating section 3. The insulating cooling liquid is cooled by air to ensure that the temperature of the insulating cooling liquid flowing out from the cooling section 3 and entering the ca...

Abstract

The invention relates to a liquid immersion cooling type automobile power battery pack, which comprises a shell body with an opening at the upper end, a cover body hermetically connected with the opening at the upper end of the shell body, and connecting terminals for connecting with an external circuit, wherein a hollow cavity chamber is formed in the cover body; a battery pack, insulating cooling liquid and a pump are arranged in the shell body; the connecting terminals are electrically connected with the battery pack; the insulating cooling liquid fills the inner space of the shell body; the pump is connected with the hollow cavity chamber of the cover body through a pipeline; and a liquid outlet for communicating the inner part of the shell body with the hollow cavity chamber is formedin the lower surface of the cover body. According to the liquid immersion cooling type automobile power battery pack, the whole battery pack is immersed in insulating cooling liquid, so that the cooling of the automobile power battery pack is realized.

Description

technical field [0001] The invention relates to the field of power batteries, in particular to a liquid immersion cooling type automobile power battery pack. Background technique [0002] With the increasingly severe energy and environmental issues, electric vehicles are gradually replacing traditional fuel vehicles and becoming an important branch of the automotive industry. Electric vehicles include three core technologies, power batteries, motors and control systems, among which power batteries are the most critical, and their performance indicators and economic costs determine the commercialization process of electric vehicles. At present, electric vehicle batteries are mainly divided into two categories-battery batteries and fuel cells, while batteries including nickel-metal hydride batteries, lithium batteries, and sodium-sulfur batteries are the focus of current market development. [0003] The power battery will generate heat during the charging process and the disc...
