[detailed description of the invention]
Hereinafter, the detailed description of the invention of the application battery bag heat management system will be introduced in conjunction with Fig. 1 to Fig. 6.
nullAs shown in Figure 1,The battery bag heat management system that the application provides includes coldplate 1、Cold plate 2 and gas-liquid phase transition medium 3,Coldplate 1 includes top board 101、First side plate 102 and the second side plate 103,Top board 101 and the first side plate 102 and the second side plate 103 are collectively forming the containing cavity holding battery modules 12,Top board 101 is positioned at the top of containing cavity,First side plate 102 and the second side plate 103 lay respectively at the both sides of containing cavity,First side plate 102 and the second side plate 103 are adjacent with the battery modules 12 in containing cavity or fit,First side plate 102 and the second side plate 103 are cavity structure,Gas-liquid phase transition medium 3 is contained in cavity structure,Adopt the problem that gas-liquid phase transition medium 3 improves the poor thermal conductivity that solid-liquid phase change medium exists,Cold plate 2 is placed in the top of top board 101,Cold plate 2 is fixedly connected by welding with top board 101 and is collectively forming a cavity,Cavity is connected with cavity structure.
As in Figure 2-4, time in order to prevent vehicle anteversion and retroversion or lateral tilting, gas-liquid phase transition medium 3 skewness problem, the application is provided with dividing plate 4 in the cavity structure of the first side plate 102 and the second side plate 103, cavity structure is divided into multiple cooling bath 5 by dividing plate 4, and each cooling bath 5 is all connected with cavity, it is preferred that dividing plate 4 is disposed longitudinally in cavity structure.Flow behavior due to gas-liquid phase transition medium 3, gas-liquid phase transition medium 3 in cooling bath 5 can occur flowing to cause gas-liquid phase transition medium 3 skewness, the interface of gas-liquid phase transition medium 3 is equal with horizontal plane, when vehicle is from when rolling or anteversion and retroversion come back to level road, it is balanced to keep the amount of gas-liquid phase transition medium 3 in cooling bath 5, the application is provided with balance pipe 8 on dividing plate 4, and what all of balance pipe 8 was all contour is arranged on dividing plate 4 so that gas-liquid phase transition medium 3 is capable of redistributing.The interface of gas-liquid phase transition material is consistently higher than balance pipe 8 so that in cooling bath 5, there is the gas-liquid phase transition medium 3 cooling for battery modules 12 of abundance in the moment.
As shown in Figure 4, independence in order to realize the two sides of battery modules 12 cools down, the application also includes partition panel 9, partition panel 9 is arranged in cavity, and separate the cavity into the first cavity and second cavity of independent closing, first cavity and the second cavity are not connected, and all cooling baths 5 of the first cavity and the first side plate 102 are all connected, and all cooling baths 5 of the second cavity and the second side plate 103 are all connected.
As shown in Figure 4, in order to intercept the liquid changed by gas-liquid phase transition medium 3, the application also includes lower baffle plate 6, lower baffle plate 6 is arranged on top board 101, lower baffle plate 6 separates the cavity into multiple every liquid zone, each is all connected with cooling bath 5 every liquid zone, leaves gap between lower baffle plate 6 and cold plate 2.As it is shown in figure 5, in order to better aforesaid liquid be carried out water conservancy diversion, the application also includes overhead gage 7, and overhead gage 7 is arranged on cold plate 2, leaves gap between overhead gage 7 and top board 101.And be not just be correspondingly arranged up and down between overhead gage 7 and lower baffle plate 6, but intert distribution, i.e. one piece of overhead gage 7, then one piece of lower baffle plate 6 is set every a segment distance, it is spaced a distance again and one piece of overhead gage 7 is set, so that leaving certain distance between overhead gage 7 and lower baffle plate 6 in the horizontal direction.After the temperature of battery modules 12 reaches the boiling point of gas-liquid phase transition medium 3 and absorbs enough heats, gas-liquid phase transition medium 3 is changed into gaseous material by liquid, after gaseous material rises and contacts with cold plate 2, cold plate 2 absorbs the heat of gas-liquid phase transition medium 3 and is converted into liquid, liquid againsts cold plate 2 flow down, assemble after encountering overhead gage 7, fall under gravity on top board 101, liquid flows on top board 101, enter corresponding every liquid zone after encountering lower baffle plate 6, then flow in corresponding cooling bath 5.Owing to leaving gap between overhead gage 7 and lower baffle plate 6, while realizing intercepting liquid, do not interfere with the flowing of the gaseous material changed by gas-liquid phase transition medium 3 yet.The cooling of cold plate 2 can adopt natural wind that it is lowered the temperature, it is possible to use it is cooled down by coolant, it is possible to use it is cooled down by the vaporizer of air conditioning system.
As seen in figs. 5-6, in order to prevent the leakage of phase-change material and facilitate the filling of gas-liquid phase transition medium 3, the application also to include filler lid 10 and filler 11, filler 11 is arranged on cold plate 2, filler lid 10 is set on filler 11, and filler 11 is connected with every liquid zone.In order to convenient the first side plate 102 to independent cooling and the second side plate 103 fill gas-liquid phase transition medium 3, the filler 11 of the application can be multiple, and corresponding first cavity and the second cavity are arranged respectively.The phase transition temperature of filling gas-liquid phase transition medium 3 is 35 DEG C~55 DEG C.When filling gas-liquid phase transition medium 3, evacuation filling need to be adopted to guarantee the gaseous material after only having gas-liquid phase transition medium 3 and low-pressure gasifying in container.
These are only the some embodiments of the application, be not all, of embodiment that the change of any equivalence that technical scheme is taked by those of ordinary skill in the art by reading present specification is claims hereof and is contained.
