[0031] The technical scheme of the utility model has the air supply outlet 23 arranged on one side of the casing 1 and in communication with the containing cavity 11, so that the cold air enters from the side of the battery monomer 6, thereby improving the heat dissipation efficiency of the cold air on the battery monomer 6, the second channel 212 has the guide inclined surface 2121, which is arranged obliquely along the air outlet direction of the air supply channel 21 and towards the containing cavity 11 from the connection between the first channel 211 and the second channel 212, so that the guide inclined surface 2121 can guide the cold air to be evenly distributed in the air supply channel 21, the cold air is evenly delivered into the containing cavity 11 through the air supply outlet 23, and the heat dissipation efficiency of the cold air on the battery monomer 6 is improved, and the problem that the cold air is gathered on the side away from the air supply outlet 23 in the air duct due to the excessively fast air speed at the air outlet of the air supply device 7 in the prior art air supply channel 21 is solved, thereby improving the service life of the battery monomer 6.

[0032] In the embodiment, the casing 1 has a receiving cavity 11 for mounting components such as the battery cell 6. The air supply member 2 is connected to the casing 1, and the air supply member 2 can be located above the receiving cavity 11, thereby facilitating the delivery of cold air from the top of the casing 1 to the bottom of the casing 1. In order to improve the efficiency of the delivery of cold air from the air supply member 2 to the receiving cavity 11, the air supply member 2 has an air supply passage 21, an air supply inlet 22 and an air supply outlet 23 which are in communication with the air supply passage 21. The air supply outlet 23 is arranged on one side of the casing 1 and is in communication with the receiving cavity 11, so that the cold air can enter the receiving cavity 11 from the side of the receiving cavity 11 and dissipate heat from the battery cell 6, thereby improving the cooling efficiency of the battery cell 6.

[0034] In the embodiment, the air guide section 24 comprises a first air guide section 241, which is connected to the external air supply device 7 by fasteners such as bolts or screws, thereby improving the stability of the connection between the air supply device 7 and the first air guide section 241, and thereby making the air supply device 7 more stably deliver cold air into the air guide section 24. The air guide section 24 can further comprise a second air guide section 242, which facilitates the communication between the first air guide section 241 and the second passage 212, thereby facilitating the delivery of cold air from the first air guide section 241 and the second air guide section 242 into the second passage 212 in sequence. By setting the opening area of the air supply inlet 22 to be larger than the opening area of the air inlet 2122, the delivery efficiency of cold air is improved.
