[0002] During the battery cell testing process, the generation and rapid accumulation of heat will inevitably cause the internal temperature of the battery to rise, especially in a high temperature environment or during high-rate charge and discharge.

[0029] Embodiment 2:
[0030] Combined with Figure 1-5 , the specific implementation of the utility model is described as follows:
[0031] like Figure 1-5As shown, a heat dissipation device for battery cell testing includes a base 1 and a battery cell body 2 installed in the base 1. Limiting frames 4 are arranged on the inner walls of the four end surfaces of the base 1, and limiting blocks 3 are installed in the limiting frames 4 through supporting springs 6, and the limiting blocks 3 are pressed on the outer wall of the battery cell body 2.

The front end face of the limit block 3 is an arc-shaped structure, and its interior is a through-type hollow structure. A number of heat dissipation fins 7 are fixedly connected to the hollow inner wall of the limit block 3. By setting a plurality of limit blocks 3 in conjunction with the support spring 6 and the limit frame 4, the battery body 2 can be clamped when testing is required, thereby maintaining the stability of the battery body 2 during the test. By arranging the limit blocks 3 at intervals and cooperating with the through-hollow design inside the limit blocks 3, it is possible to facilitate the contact between the battery body 2 and the air, and facilitate air circulation, so as to ensure the normal heat dissipation of the battery body 2 and improve the heat dissipation efficiency.
[0033] A water storage seat 5 is arranged in the base 1 outside the battery body 2 . A groove 15 for engaging the limit block 3 is arranged on the outer wall of the water storage seat 5 . The battery body 2 is at least partially embedded in the water storage seat 5 .
[0034] Among them, both sides of the base 1 are provided with a slide groove 8, and both sides of the outer wall of the water storage base 5 are fixedly connected to the limit plate 9, and the outer end of the limit plate 9 passes through the slide groove 8.

When the battery body 2 is tested and the temperature rises unexpectedly and rapidly, the water storage seat 5 is moved upward to wrap and fit the battery body 2, and the water storage seat 5 is cooled by cooling water.
