The heat-sensitive structure 151 can also be shunk when 200 temperature of the battery modules increases, and the stripper plate 153 is driven to move, and be increased
The squeezing action power that the big inlet tube 110 is subject to, reduces the flow of liquid.The battery modules 200 are being heated as a result,
In the process, by the control of the temperature difference of the battery modules 200 in relatively low range.
If the inlet tube 110 can pour into use through the inlet tube 110 for cooling down into the fluid course of flat tube 130
In the liquid of cooling.The heat-sensitive structure 151 can be expanded when 200 temperature of the battery modules increases, and drive the stripper plate
153 movements, reduce the squeezing action power that the inlet tube 110 is subject to, increase the flow of liquid, pass through liquid and the battery mould
Heat exchange between group 200, reduces the temperature of the battery modules 200.Conversely, the heat-sensitive structure 151 can also be in the electricity
Module 200 temperature in pond is shunk when reducing, and is driven the stripper plate 153 to move, is increased the squeezing action that the inlet tube 110 is subject to
Power reduces the flow of liquid.As a result, during being cooled down to the battery modules 200, by the temperature of the battery modules 200
Difference control is in relatively low range.
Optionally, the inlet tube 110 can also include two pipes, that is, include the first inlet tube 111 and the second inlet tube
