Problems solved by technology

[0008] 3. For those who use thermal conductive adhesive, generally because it is preformed or injected into a pre-set container, it is difficult to make the thermal conductive adhesive contact the battery case without gaps, the thermal resistance of the gap is extremely high, and the overall heat transfer efficiency is low
[0009] 4. Cooling with fluid circulation, especially liquid cooling, works very well. The disadvantage is that the structure is complex, and pumps and fans are needed. These rotating parts are easy to damage and consume extra energy. If liquid working fluid is used, there is also liquid leakage The danger of increasing the difficulty of leak prevention

Embodiment 1

[0063] Figure 1 to Figure 10 A specific application example of the heat conduction assembly of the present application in a large-capacity battery (also called a battery module in the industry) is shown. The heat conduction assembly includes a hard heat conductor 1, the side of the hard heat conductor 1 is formed with a plurality of grooves 101 adapted to the outer wall of the cylindrical battery, and a flexible heat conductor is formed on the groove wall of each groove 101 The accommodating chamber 102, and the flexible heat conducting body 2 is arranged in the accommodating chamber 102 of the flexible heat conducting body. The large-capacity battery includes a battery holder 5 with numerous battery insertion holes, and a large number of cylindrical batteries 3 respectively inserted in each battery insertion hole, and each battery insertion hole is distributed in a matrix on the battery holder 5, so the insertion The various cylindrical batteries 3 contained in the battery ...

Embodiment 2

[0084] refer to Figure 11 As shown, in this embodiment, the heat conduction assembly also includes a rigid heat conductor 1, and the side of the rigid heat conductor 1 is formed with a plurality of (4) grooves 101 adapted to the outer wall of the cylindrical battery, each A flexible heat conductor accommodating cavity 102 is formed on the groove wall of the groove 101 , and a flexible heat conductor 2 is disposed in the flexible heat conductor accommodating cavity 102 . The main difference between this embodiment and the heat conduction assembly in Embodiment 1 is that only one expansion hole 103 is provided in the rigid heat conduction body 1 . When the heat-conducting assembly is loaded into a high-capacity battery and deformed by extrusion, it will come into contact with four cylindrical batteries.

Abstract

The application discloses a heat conducting component, a high-capacity battery equipped with the heat conducting component and a manufacturing method of the high-capacity battery. The heat conducting component comprises hard heat conductors, wherein grooves adaptive to external wall faces of cylindrical cells are formed in side parts of the hard heat conductors, flexible heat conductor accommodating chambers are formed in groove walls of the grooves, and flexible heat conductors are arranged in the flexible heat conductor accommodating chambers. The heat conducting component disclosed by the application can be in close contact with the external wall face of each cylindrical cell in the high-capacity battery during application, thus, the heat transfer rate between the heat conducting components and the cylindrical cells is increased, and then, the heat dissipating efficiency of the high-capacity battery is increased.

Description

technical field [0001] The present application relates to the field of battery technology, and in particular to a heat conduction assembly for a battery, a large-capacity battery equipped with the heat conduction assembly, and a manufacturing method of the large-capacity battery. Background technique [0002] In today's great economic development, electronic technology is at the forefront. Various multifunctional electronic devices represented by mobile phones have entered every aspect of people's daily life and become necessities. In order to reduce air pollution and protect the environment, vehicles that have traditionally used fuel have also been electrified, and the development of electric vehicles is also in full swing. [0003] All electrical equipment, especially electric vehicles, must be powered by an independent power source - the battery. Limited by the space and weight of the equipment, the required battery must be small in size, light in weight, large in energ...
