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

Abstract

The invention discloses a large-capacity battery with a heat-dissipating device, which is a large-capacity battery composed of several cylindrical single cells in parallel. Longitudinal and transverse slits are formed between these cylindrical single cells, a number of fins are inserted in the longitudinal slits and / or the transverse slits, and a number of fins are arranged on the fins, and the fins are tightened. Press on the outer wall surface of the cylindrical single battery, so that the heat sink and the cylindrical single battery are fixed to each other. The large-capacity battery of the invention has simple structure, convenient assembly, large contact area between the heat sink and the cylindrical battery cell, and ensures the contact reliability between the heat sink and the cylindrical battery cell during use, thereby improving the large-capacity battery. Heat dissipation efficiency, while ensuring the consistency of temperature in large-capacity batteries.

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...
