Problems solved by technology

[0002] A prismatic battery module requires several prismatic batteries to be stacked and connected together in turn. Two adjacent prismatic batteries are usually separated by a separator, and the prismatic battery module generates heat during use. In normal use of the battery pack, the prismatic battery module is generally cooled, and the cooling methods include air cooling and liquid cooling. The intermediate carrier has low heat exchange efficiency. At the same time, due to the use of pipeline cooling, the battery module or battery pack is large in size and heavy in weight; sometimes in order to ensure that the volume and weight of the battery module meet the requirements, the layout of the cooling pipeline is not very comprehensive. Sometimes one cooling pipe corresponds to multiple batteries and cannot cover the battery in all directions. The contact area between the battery and the cooling pipe is small, resulting in poor cooling effect of the battery, and even heat accumulation, which affects the performance and service life of the battery module.

Embodiment 1

[0025] A kind of square battery module separator 1, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the main body 101 is included, and the main body 101 is a rectangular parallelepiped frame structure completely open on both sides. The main body 101 is divided into two square battery module placement areas 103 by the isolation plate 102. Three distribution grooves 104 are arranged on both sides of the upper end, and the left and right two distribution grooves 104 are arranged on the same side of the isolation plate 102, and the middle distribution groove 104 is arranged on the other side of the isolation plate 102, and the lower end of the isolation plate 102 is connected to each distribution groove 104 Corresponding positions are evenly opened with four independent channels 105 from top to bottom with the upper end closed and the lower end open, that is, one distribution channel 104 corresponds to four channel channels 105, and the channel 105 com...

Embodiment 2

[0027]A square battery module separator, its structure is similar to the structure of the square battery module separator in Implementation 1, the difference is that the number of splitters on the top of the separator is four, and the four splitters are distributed On both sides of the isolation plate, the middle two splitters are set on the same side of the isolation plate, the left and right two splitters are set on the other side of the isolation plate, and the lower ends of the isolation plate are respectively opened at positions corresponding to each splitter. The number is three, that is, one splitter slot corresponds to three through slots, and the communication part between the splitter slot and the through slot is located at 1 / 2 of the total height of the isolation plate.

Embodiment 3

[0029] A square battery module separator, its structure is similar to that of the square battery module separator in Implementation 1, the difference is that the number of splitters on the top of the separator is two, and the two splitters are set On the same side of the separation plate, the number of through grooves respectively opened at the positions corresponding to the lower ends of the separation plate and each splitter groove is five, that is, one splitter groove corresponds to five through grooves.

Abstract

The invention provides a separator for a square battery module, the body is divided into two square battery module placement areas by the separator, the separator is parallel to both sides of the body, and several shunt grooves are arranged on one or both sides of the upper end of the separator , the lower end of the isolation plate corresponds to each splitter groove, and there are several independent through grooves from top to bottom, with the upper end closed and the lower end open. There are two liquid outlets, and the liquid outlets communicate with the through grooves one by one. The top of the body is vertically provided with a raised liquid inlet groove, and the bottom of the raised liquid inlet groove is provided with several liquid inlets. One-to-one connection. Also provided is a prismatic battery module made using the separator of the present invention. The separator of the square battery module of the present invention has a simple and novel structure and is convenient to use. The square battery module produced by using the partition plate directly contacts the battery surface with the cooling liquid and the contact area is large, and the battery cooling effect is better.
