[0024] Referring to Figures 1-4 as shown, it is a preferred embodiment provided by the present invention.
[0025] The contact-type battery baking heat conduction structure provided by the present invention includes a material box 200 for placing battery cells and a heating plate 100. The top of the heating plate 100 has a placement surface, and a plurality of upwardly protruding heat conduction blocks 110 are provided on the placement surface. The plurality of heat conduction blocks 110 are arranged in an array on the placement surface to form a placement position; the bottom of the material box 200 is pressed against the placement position, and a plurality of through holes 201 penetrating up and down are formed in the material box 200, and the plurality of heat conduction blocks 110 are respectively embedded into the through holes 201;
[0026] When battery cells are placed in the material box 200, the bottom of the battery cells is pressed against the top of the heat conduction blocks 110.
[0027] For the above-mentioned contact-type battery baking heat conduction structure, by placing the material box 200 in the placement position and the heat conduction blocks 110 are correspondingly embedded in the through holes 201, the battery cells in the material box 200 can be directly in contact with the heat conduction blocks 110, and the heat conduction blocks 110 can directly heat the battery cells, greatly improving the heat transfer efficiency.
[0028] The top of the material box 200 has a top surface, and a plurality of placement grooves 202 formed by downward depressions are formed on the top surface. The placement grooves 202 are for placing battery cells, and the plurality of placement grooves 202 are arranged in an array on the top surface and are arranged separately from each other. In this way, through the design of the plurality of placement grooves 202, it is ensured that the battery cells are stably placed during the heat transfer process.
[0029] Specifically, the bottom of the material box 200 has a flat bottom surface, so a plurality of through holes 201 penetrating up and down are formed on the bottom surface, and the top of the through holes 201 is connected to the bottom of the placement grooves 202. In this way, the bottom of the battery cells placed in the placement grooves 202 can be pressed against the heat transfer blocks.
[0030] As a preferred embodiment, the placement grooves 202 and the embedding grooves are arranged coaxially and aligned up and down.
[0031] As a preferred embodiment, the top of the heat conducting block 110 is flush with the bottom of the placement groove 202. In this way, the bottom of the battery cell placed in the placement groove 202 can be pressed against the bottom of the placement groove 202 and simultaneously contact the top of the heat conducting block 110, ensuring stable placement of the battery cell.
[0032] Specifically, a plurality of placement positions are formed on the placement surface, and the plurality of material boxes 200 are correspondingly placed on the placement positions, and the plurality of material boxes 200 are arranged at intervals on the placement surface. In this way, a plurality of placement positions can be provided on one heating plate 100, and thus a plurality of material boxes 200 can be heated simultaneously.
[0033] The bottom surface and the placement surface are in surface-to-surface contact. In this way, the complete surface-to-surface contact can improve the heat transfer efficiency.
[0034] Specifically, the plurality of heat conducting blocks 110 are arranged in a matrix array on the placement surface to form placement positions.
[0035] Specifically, the plurality of placement grooves 202 are arranged in a matrix-like array on the top surface.
[0036] The top of the heat conducting block 110 has a flat heat conducting surface. In this way, the battery cell placed in the placement groove 202 can contact the top of the heat conducting block 110 with the largest area, improving the heat transfer efficiency.
[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
