As shown in Figure 1-3, Fig. 1 is a kind of structural schematic diagram of battery liquid cooling apparatus proposed by the present invention；Fig. 2 is the present invention
The structural schematic diagram of diaphragm seal described in a kind of battery liquid cooling apparatus proposed；Fig. 3 is a kind of battery system proposed by the present invention
Structural schematic diagram.
Referring to Fig.1-2, a kind of battery liquid cooling apparatus that the embodiment of the present invention proposes, comprising: inside has medium runner 12
Liquid cooling plate 1, liquid cooling plate 1 is equipped at least one duct 11 for being connected to its interior media runner 12, on liquid cooling plate 1 and is located at
The diaphragm seal 13 for being sealed to the port is equipped at the port in any one duct 11, and the diaphragm seal 13 is equipped with
Indentation 131, the indentation 131 are ring structure, and the indentation 131 be located at it is on the inside of duct 11 and coaxially arranged with duct 11, and
In specific production process, the depth of indentation 131 can be set according to the actual situation, to assign diaphragm seal 13 different unlatching pressures
Power, to adjust the different jet powers that the inside and outside differential pressure of liquid cooling plate 1 realizes 1 interior media of liquid cooling plate.
Diaphragm seal 13 is arranged by the way that duct 11 is arranged on liquid cooling plate 1 in the present invention at the port in duct 11, close to utilize
Mounting 13 is sealed duct 11；By the way that indentation 131 is arranged on diaphragm seal 13, and make 131 ring structure of indentation, and carves
Trace 131 is located at the inside of duct 11 and coaxially arranged with duct 11, to be made inside liquid cooling plate 1 using the indentation 131 on diaphragm seal 13
Pressure can make diaphragm seal 13 split along indentation 131 when increasing, so that the medium in liquid cooling plate 1 is under the action of inside and outside differential pressure
It is sprayed out of duct 11, plays the role of cooling and fire extinguishing.The battery liquid cooling apparatus substitutes the sealing of melt material using diaphragm seal 13
Mode can to avoid hot melt material because caused by the heated characteristic easily melted the unexpected conducting in duct 11 open phenomenon, so as to effective
Enhance the reliability that duct 11 seals.
In addition, diaphragm seal 13 is equipped with protecting film 14 far from the side of 11 inner cavity of duct, the protecting film 14 in the present embodiment
Outer edge and liquid cooling plate 1 are fixed, and liquid cooling has spacing between the protecting film 14 and diaphragm seal 13.The setting of protecting film 14 can be
Diaphragm seal 13 is to prevent foreign matter from causing diaphragm seal 13 because of breakage from external world's touching diaphragm seal 13 when opening.
In the present embodiment, protecting film 14 is plastic foil.
In the present embodiment, duct 11 include deep gouge portion and positioned at deep gouge portion bottom and be connected to deep gouge portion and medium runner 12
11, duct, diaphragm seal 13 is bonded and is welded and fixed with the bottom in deep gouge portion, to form the sealing to 11, duct.The knot
Structure setting can be with
In the present embodiment, diaphragm seal 13 is made by aluminum material material.
In the present embodiment, the internal diameter in duct 11 is 1mm~7mm.
Referring to Fig. 3, a kind of battery system, including several batteries 2 and battery liquid cooling apparatus as described above, wherein
