Fig. 1 and Fig. 2 is referred to, the present invention provides a kind of electrokinetic cell bag liquid cooling apparatus 100, including is contained in battery bag
For the cold pipeline 10 of liquid of coolant circulation, the cold pipeline 10 of liquid is serpentine-like and is parallel to each other and uniform intervals are set including N number of
The endothermic tube 11 and (N-1) put are individual for connecting and connecting the connecting tube 12 of two neighboring endothermic tube 11, and wherein N is not less than 2
Positive integer.
Specifically, the endothermic tube 11 is in pantograph structure and including multiple unit for scaling 111 being sequentially connected, each scaling
Unit 111 includes expansion segment 1111 and contraction section 1112, and the expansion segment 1111 of each unit for scaling 111 and adjacent one scaling
The contraction section 1112 of unit 111 is connected.Into the coolant in the cold pipeline 10 of the liquid from the expansion of each unit for scaling 111
Section 1111 flows to the contraction section 1112 of the unit for scaling 111.
Further, in each unit for scaling 111, excessively stream of the expansion segment 1111 away from described one end of contraction section 1112
Area is equal with area of passage of the contraction section 1112 away from described one end of expansion segment 1111 and is less than the expansion segment 1111
With the area of passage of the intersection of contraction section 1112.
