Optionally, the housing 11 may be made of a metal material, and the metal includes at least one of copper and aluminum. It is understood that the housing 11 is a copper shell, an aluminum shell, or a copper-aluminum alloy housing 11.
Referring to fig. 5 and 6, in some embodiments of the present application, the direct-cooling battery cabinet 10 further includes a heat sink 15, the heat sink 15 is disposed in the second receiving sub-cavity 113, and the heat sink 15 is thermally connected to the heat exchange plate 13.
The cooling fin 15 of the embodiment of the application is arranged in the second accommodating sub-cavity 113 and is in heat conduction connection with the heat exchange plate 13, so that the heat dissipation area is increased. When the heat of the battery module 16 is conducted to the second sub-receiving cavity 113 through the heat exchange plate 13, the heat dissipation fins 15 increase the heat dissipation area, which is beneficial to removing the heat of the battery module 16 more efficiently, and improves the heat dissipation efficiency of the direct cooling type battery cabinet 10.
Optionally, the heat sink 15 includes at least one of a silver sheet, a copper sheet, an aluminum sheet, and a steel sheet. The material of the heat dissipation sheet 15 has a high heat conduction effect, and the heat conduction effect is good, which is beneficial to improving the heat dissipation efficiency of the direct cooling type battery cabinet 10. When the heat sink 15 is a silver plate, the heat sink 15 has a good heat conduction effect, but the price thereof is high, which further increases the production cost of the direct cooling type battery cabinet 10.
Optionally, in some embodiments of the present application, the heat sink 15 includes a body 151 and a protrusion 152 on a surface of the body 151. In the embodiment of the present application, the protruding structures 152 on the surface of the body part 151 are beneficial to increase the heat dissipation area, and are beneficial to further improve the efficiency of removing heat from the battery module 16, and improve the heat dissipation efficiency of the direct-cooling battery cabinet 10.
In some embodiments, the protruding structure 152 on the surface of the body 151 is an integrally formed structure, and in other embodiments, the protruding structure 152 on the surface of the body 151 may be formed separately and then assembled or welded together.
Optionally, in some embodiments, a distance between two farthest points of the protruding structure 152 on an area enclosed by an orthographic projection of the surface of the body portion 151 facing the protruding structure 152 ranges from 2mm to 4mm. Specifically, the distance between two points farthest away on the area enclosed by the orthographic projection of the protruding structure 152 on the surface of the body portion 151 facing the protruding structure 152 may be, but is not limited to, 2mm, 2.1mm, 2.3mm, 2.7mm, 3.0mm, 3.2mm, 3.5mm, 3.7mm, 3.9mm, and 4mm.
When the distance between two points farthest away from each other on the region surrounded by the orthographic projection of the protrusion structure 152 on the surface of the main body 151 facing the protrusion structure 152 satisfies the range of 2mm to 4mm, the distance between the protrusion structures 152 is within a reasonable range, which not only increases the heat dissipation area in the first receiving sub-cavity 112 and improves the heat dissipation efficiency of the direct-cooling battery cabinet 10, but also provides a larger airflow space for the cool air blown out by the refrigerator 14. When the distance between two farthest points of the protruding structures 152 on the area surrounded by the orthographic projection of the main body 151 facing the protruding structures 152 is greater than 4mm, the distance between the protruding structures 152 is too large, the number of the protruding structures 152 in a unit area is reduced, the heat dissipation area in the first sub-cavity 112 is reduced, and the heat dissipation efficiency of the direct-cooling battery cabinet 10 cannot be further improved. When the distance between two farthest points of the protruding structure 152 on the area surrounded by the orthographic projection of the main body 151 facing the protruding structure 152 is less than 2mm, the processing difficulty is increased, and the distance between the protruding structures 152 is too small, the arrangement of the protruding structures 152 is too close, the flowing resistance of the cold air blown by the refrigerator 14 is increased, and the heat dissipation efficiency of the direct-cooling battery cabinet 10 is reduced.
It is understood that the protrusion 152 on the surface of the body 151 may be a needle-like structure, a sheet-like structure, or a regular or irregular part such as a hemisphere, etc. on the surface of the body 151. The regular or irregular parts such as the needle-shaped, the sheet-shaped structure or the hemispherical structure can provide more heat dissipation areas for the heat dissipation fins 15, which is beneficial to increasing the heat dissipation speed of the heat dissipation fins 15.
Alternatively, in some embodiments, when the raised structures 152 are sheet structures, the thickness of the sheet structures may range from 0.8mm to 1.5mm, and in particular, the thickness of the sheet structures may be, but is not limited to, 0.8mm, 1.0mm, 1.1mm, 1.25mm, 1.3mm, 1.35mm, 1.4mm, and 1.5mm. When the thickness of the sheet structure satisfies the range of 0.8mm to 1.5mm, the thickness of the sheet structure is within a reasonable range, which can provide a large heat dissipation area for the heat dissipation fins 15. When the thickness of the sheet structure has a value greater than 1.5mm, it is easy to cause the mass of the projection structure 152 to be too large, and this may result in an increase in cost; when the thickness of the sheet structure is less than 0.8mm, the protrusion structure 152 is too small, and the processing difficulty is large.
Alternatively, in some embodiments, when the protruding structure 152 is a sheet-like structure, the height of the sheet-like structure ranges from 20mm to 50mm, and specifically, the thickness of the sheet-like structure may be, but is not limited to, 20mm, 21mm, 23mm, 27mm, 30mm, 35mm, 38mm, 39mm, 41mm, 45mm, 47mm, 50mm, and the like. When the thickness of the sheet structure satisfies the range of 20mm to 50mm, the thickness of the sheet structure is within a reasonable range, which can provide a large heat dissipation area for the heat dissipation fins 15. When the thickness of the sheet structure is greater than 50mm, the processing difficulty is increased, and the flow resistance of the cold air blown out from the refrigerator 14 is increased, which reduces the heat dissipation efficiency of the direct-cooling type battery cabinet 10. When the thickness of the sheet structure is less than 20mm, the heat dissipation area provided by the sheet structure to the heat dissipation fins 15 is small, and the heat dissipation efficiency of the direct-cooling type battery cabinet 10 cannot be further improved.
Optionally, the material of the protruding structure 152 is selected from one or more of silver, copper and aluminum, and the material of the protruding structure 152 may be, but is not limited to, silver, copper, aluminum, silver-copper alloy, silver-aluminum alloy, copper-aluminum alloy, silver-copper-aluminum alloy, and the like.
