[0019] Please see Figures 1 to 5In one aspect, this invention provides a quick-connect fitting 100 for an automotive battery cooling plate, comprising a connecting pipe 110 and two connecting assemblies 120 respectively disposed at both ends of the connecting pipe 110; the connecting pipe 110 has a medium channel 111 through which a cooling medium can pass; the connecting assembly 120 includes a male connector 121, a female connector 122, and a claw 123; the female connector 122 is connected to the end of the connecting pipe 110 and communicates with the medium channel 111; the claw 123 surrounds the outside of the female connector 122 and forms a slot 127; the male connector 121 is slidably connected to the female connector 122; the male connector 121 can move within the slot 127 and can be inserted into the slot 127; the male connector 121 has an annular boss 124 at one end near the female connector 122, and the claw 123 can engage with the annular boss 124.

[0020] The quick-connector for automotive battery cold plates of the present invention requires only manual alignment during assembly, which is more convenient than the prior art that uses non-standard equipment to press and align the cold plates and two-color injection-molded tubes. In addition, the connecting tube 110, female connector 122 and claw 123 in the connecting assembly 120 all have elastic properties. Therefore, when assembling between cold plates 200 with short spacing, it can absorb the assembly allowance tolerance between the cold plates 200, which is more conducive to installation in narrow installation spaces.

[0021] For example, to facilitate the insertion of the male connector 121 into the slot 127, the annular boss 124 is provided with a first inclined surface 128 on the side near the slot 127, and the end of the claw 123 is provided with a second inclined surface 129 that cooperates with the first inclined surface 128.

[0022] For example, to prevent leakage of cooling medium, a sealing ring 125 is provided between the male connector 121 and the female connector 122 in one of the connection assemblies 120; wherein, the female connector 122 is provided with an annular groove 126 for placing the sealing ring 125, and the structure is compact.

[0023] For example, the claw 123, the connecting pipe 110, and the two female connectors 122 disposed at both ends of the connecting pipe 110 are integrally formed, which is more conducive to production.

[0024] For example, the materials of the claw 123, the female connector 122, and the connecting pipe 110 are preferably PA12 (polydodecanoic acid) with excellent elasticity and cold resistance.

[0025] Additionally, please see Figures 1 to 6In another aspect, this invention provides an automotive battery cooling device, which includes multiple spaced-apart cold plates 200 and multiple quick-connectors 100 for the automotive battery cold plates as described above. Each cold plate 200 has a connecting plate extending from its edge, and the connecting plate has a through hole 211. Each quick-connector 100 for the automotive battery cold plates is disposed between two of the connecting plates. A male connector 121 is disposed on the connecting plate and communicates with the through hole 211. Multiple quick-connectors 100 for the automotive battery cold plates are joined together to form a cooling channel 300. The cooling channel 300 communicates with the interlayer channel of the cold plates 200 to form a circulation path.

[0026] It should be noted that in this embodiment, the male connector 121 is welded to the cold plate 200.

[0027] It should be noted that since the automotive battery cooling device includes the automotive battery cold plate quick connector 100 described above, it has the same beneficial effects as the automotive battery cold plate quick connector 100, and will not be repeated here.

[0028] For example, the cooling channel 300 extends along the X-axis direction, and multiple cooling channels 300 are provided, which are arranged at intervals along the Y-axis direction. This design can utilize the elastic properties of the connecting pipe 110, the claw 123, and the female connector 122 to absorb a 2-4 mm assembly tolerance between the cold plates 200 in the X-axis direction; and to absorb a 2-3 mm assembly tolerance caused by the installation of the cold plates 200 or the welding of the male connector 121 in the Y-axis direction.

[0029] For example, the quick-connect components 100 of the automotive battery cold plates in each of the cooling channels 300 are arranged in a staggered manner; the connecting plate includes a plurality of first connecting plates 212 and a plurality of second connecting plates 213, the first connecting plates 212 and the second connecting plates 213 being arranged alternately along the X-axis direction, the second connecting plates 213 protruding from the first connecting plates 212, and the second connecting plates 213 being provided with avoidance grooves 214 for avoiding the connecting pipe 110. This design can improve space utilization, facilitate the flow of cooling medium, and accelerate the heat dissipation efficiency between the cold plates 200.
