In this way, the frame 100 can quickly and evenly transfer heat to the battery cells 300, thereby achieving rapid and uniform heating of the battery cells 300.
[0027] The top of the square frame 200 has a ring-shaped top surface, and a plurality of hollow grooves 102 are formed on the top surface. In this way, the exposed surface area of the frame 100 is increased by the design of the hollow grooves 102, while the material consumption is reduced.
[0028] The top surface is provided with four upper convex strips 230 protruding upward, and the upper convex strips 230 are arranged at intervals on the two short side walls 220 or the two long side walls 210, and the four upper convex strips 230 are arranged symmetrically in pairs.
