It is interior, and contacted with the cavity wall of battery accommodating chamber 41, to allow single battery to be produced in the course of work of battery modules
Raw heat transfer to battery compartment 4, battery compartment 4 is all connected with the top 1 of battery and bottom 2, and entire bracket is adopted
It is made of metal material, thus aforementioned heat quickly can be conducted and be distributed；Meanwhile bracket made of metal material
Structural strength is relatively high, thus battery modules provided herein can meet the design requirement of heat management and intensity simultaneously.
Further, after single battery is installed, thermal conductive insulation glue can be filled into the gap of the two, so that
The overwhelming majority on single battery surface can be contacted with aforementioned cavity wall, to further promote the conduction effect of heat between the two
Rate；Meanwhile by filling thermal conductive insulation glue between single battery and battery accommodating chamber 41, single battery can also be enhanced and propped up
The fastness of installation site in frame, to prevent the battery modules during the work time, single battery, which occurs that shake or shake, etc. is asked
Topic, and reduce the safety of entire battery modules.Specifically, in the design of bracket and manufacturing process, according to single battery
Size is different, can correspond to the size for changing the gap between single battery and the cavity wall of battery accommodating chamber 41, optionally,
Gap between both may remain in 0.5mm or so, to not only can guarantee two after having filled thermal conductive insulation glue
There is preferable heat conduction efficiency and safety between person, while the mass energy density of battery modules will not be made to reduce
It is more.
It is excellent it is possible to further by the radiating efficiency of lifting bracket, carry out to be promoted the rate of temperature fall to single battery indirectly
Selection of land, as shown in figures 1 and 3, side 3 could be formed with liquid cooling chamber 33, inlet 31 and liquid outlet 32, and inlet 31 passes through liquid
Cold chamber 33 is connected to liquid outlet 32, and correspondingly, inlet 31 and liquid outlet 32 can cooperate with liquid cooling equipment, with to bracket into
Row cooling.Optionally, bracket can be connected to liquid cooling equipments such as such as water coolings, this can guarantee that it is preferable cold that battery modules have
But the processing and use cost of battery modules are reduced in the case where effect, as far as possible, the size and specific structure of liquid cooling chamber 33 can be with
Corresponding design according to the actual situation, it should be noted that in the design process of battery modules, it is close that volume, energy can be integrated
The many factors such as degree, structural strength and radiating efficiency consider, and according to actual needs, choose whether at the top of bracket 1
With corresponding liquid cooling chamber 33 is set on bottom 2, in this regard, being not construed as limiting herein.
In order to further enhance the radiating efficiency to single battery in the battery modules, it is preferable that as shown in figure 4, bracket
It can also include middle part heat-conducting layer 5, middle part heat-conducting layer 5 is arranged between top 1 and bottom 2, is provided with electricity on middle part heat-conducting layer 5
Pond mounting hole can make single battery pass through battery settling hole, and be mounted on bracket during assembling the battery modules
It is interior, correspondingly, between single battery and the hole wall of battery settling hole can also be filled with thermal conductive insulation glue, middle part heat-conducting layer 5 with
Side 3 connects, thus in the course of work of battery modules, single battery can also be by the middle part that is located therein at position
Heat-conducting layer 5 is by a part of heat transfer to side 3, and further to promote the radiating efficiency of single battery, this can also make list
Temperature on body battery everywhere is consistent substantially, to promote the service life of single battery；In addition, by making single battery
Middle part be fixed in battery settling hole, by the middle part heat-conducting layer 5 connecting with side plate, can also further promote monomer
