Problems solved by technology

[0003] The existing air-cooled thermal management technology has high requirements on the ambient temperature, and the temperature of the inlet air is difficult to control, which makes it difficult to control the temperature of the battery
Due to the small heat transfer coefficient of air, the efficiency of heat dissipation and cooling is low, and the uneven flow of air will lead to uneven temperature distribution in the battery pack, which will affect the temperature consistency of the power

Example Embodiment

[0020] Combine below Figure 1 to Figure 3 Embodiments of the present invention will be described in detail.

[0021] like figure 1 As shown, in one embodiment of the present invention, the submerged battery cooling box 10 includes a box body 26, the box body 26 is provided with a liquid inlet 12 and a liquid outlet 14, and the battery 16 is arranged in the box body 26 And contains a cooling liquid, wherein the battery 16 is submerged in the cooling liquid.

[0022] In this embodiment, the cooling liquid flows in from the liquid inlet 12 and flows out from the liquid outlet 14 . like figure 2 As shown, the liquid inlet 12 and the liquid outlet 14 are arranged on the same side wall of the box body 26; of course, they can also be arranged on different side walls. As long as the cooling liquid can fully submerge the battery 16 , and the range where the cooling liquid flows can completely cover any battery 16 .

[0023] In one embodiment of the present invention, the box bod...

Abstract

The invention provides an immersed battery heat dissipation box (10). The heat dissipation box includes a box body (26); the box body (26) is provided with a liquid inlet (12) and a liquid outlet (14); the internal of the box body (26) is provided with batteries (16) and accommodates a liquid coolant; and the batteries (16) are immersed in the liquid coolant. The purpose of providing the heat dissipation box which can directly transmit the heat of the batteries to the liquid coolant can be achieved, so that heat transfer efficiency can be higher, and the whole temperature of the batteries canbe more uniform.

Description

technical field [0001] The invention relates to the field of batteries, and more specifically, to a submerged battery cooling box. Background technique [0002] With the increasingly serious environmental problems, the sales of energy vehicles have increased year after year. The power battery is the heart of electric vehicles and directly affects the performance of electric vehicles. Moreover, the power battery has a large working current and generates a lot of heat. At the same time, the battery pack is in a relatively closed environment, and the heat cannot be well exported, which will lead to high or uneven temperature of the battery and affect the service life of the car. At present, commonly used heat sinks are air-cooled heat sinks and liquid-cooled heat sinks. Air-cooled heat dissipation devices are often divided into natural cooling devices and forced cooling devices. [0003] Existing air cooling and thermal management technologies have high requirements on ambie...
