Problems solved by technology

[0003] However, such large-capacity batteries generate considerable heat when charging and discharging
If the heat generated during charging and discharging cannot be effectively released, the heat will accumulate in the single battery, causing uneven temperature of the large-capacity battery, reducing the service life of the battery, and in severe cases, causing a safety accident for the large-capacity battery

Embodiment Construction

[0023] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

[0024] Figure 1 to Figure 3 A specific embodiment of the large-capacity battery with heat dissipation device of the present invention is shown. The same as the traditional large-capacity battery, the large-capacity battery also includes a clamp 1, and several Cylindrical unit cells 2, and a plurality of longitudinal gaps 3 and a plurality of transverse gaps 4 formed between these cylindrical unit cells. The "longitudinal" and "horizontal" mentioned in this embodiment are relative terms, and they are two direct...

Abstract

The invention discloses a high-capacity battery with a heat dissipating device. The high-capacity battery consists of a plurality of cylindrical single batteries which are connected in parallel and comprises a fixture and the cylindrical single batteries mounted on the fixture and connected in parallel, as well as longitudinal gaps and transverse gaps, which are formed between the cylindrical single batteries, wherein a radiating fin is inserted into the longitudinal gaps and/or the transverse gaps; a plurality of elastic heat conducting sheets are fixedly arranged on the radiating fin; each elastic heat conducting sheet is provided with an inwardly concave arc surface compressed and fitted onto the outer wall surface of one of the cylindrical single batteries. The high-capacity battery is simple in structure and convenient to assemble; the contact areas between the radiating fin and the cylindrical single batteries are large; the radiating fin and the cylindrical single batteries are guaranteed to be in reliable contact during use, so that the heat radiating efficiency of the high-capacity battery is improved, and meanwhile, the consistency of temperature in the high-capacity battery is guaranteed.

Description

technical field [0001] The invention relates to a large-capacity battery, in particular to a large-capacity battery with a heat dissipation device, and belongs to the technical field of battery heat dissipation. Background technique [0002] Some existing large-capacity batteries generally include a battery fixture and a plurality of cylindrical battery cells, wherein the battery fixture is provided with multiple vertical slots for the battery cells to be inserted and fixed, and these slots are generally evenly spaced vertically and horizontally on the battery fixture. Arrangement, these cylindrical battery cells on the same fixture are connected in parallel, so that each cylindrical battery cell inserted and fixed on the battery fixture is also arranged vertically and horizontally. After each cylindrical battery cell is inserted on the battery holder to form the large-capacity battery, there is a certain gap because two adjacent battery cells are not close together, so that...
