Embodiment 1

[0030] This embodiment provides a battery case and a battery with a serpentine heat dissipation pipe. The outer surface of the battery case and the battery is provided with a heat dissipation pipe. During the use of the battery, the condensed working medium inside the heat dissipation pipe can evenly heat the surface of the battery. , keep the temperature of each part of the battery consistent, solve the problem of heat accumulation and uneven conduction inside the battery, and quickly conduct the heat generated by the battery, so that the battery can be charged and discharged quickly, increase the number of times of battery charge and discharge, and prolong the service life of the battery .

[0031] Specifically, combined with figure 1 and figure 2 shown. figure 1 It is a cross-sectional schematic diagram of a battery case with a serpentine heat pipe; figure 2 It is a schematic diagram of a longitudinal section of a battery with serpentine heat pipes.

[0032] The batte...

Embodiment 2

[0038] This embodiment provides a battery case and a battery in which heat pipes are welded to the outer surfaces of the four side plates.

[0039] Specifically, combined with image 3 as shown, image 3 It is a schematic diagram of a battery with heat pipes welded on the outer surfaces of the four side plates.

[0040] The difference from Example 1 is that the heat dissipation pipes 2 are respectively connected to the outer surfaces of the front, rear, left, and right side plates of the battery case body 1 by welding. same. Compared with Embodiment 1, the design of this embodiment increases the heat dissipation area of ​​the battery and further improves the heat dissipation efficiency of the battery. .

Embodiment 3

[0042] This embodiment provides a battery case and a battery in which the heat dissipation pipe 2 is integrally formed with the front side plate of the battery.

[0043] Specifically, combined with Figure 4 as shown, Figure 4 It is a schematic diagram of the battery in which the heat pipe is integrally formed with the front side plate.

[0044] The difference from Embodiment 1 is that the battery case and the heat dissipation pipe 2 of the battery provided in this embodiment are integrally formed with the outer surface of the front side plate of the battery case body 1, and a condensing working medium inlet 6 and a condensing fluid inlet 6 are provided at both ends of the heat dissipation pipe. The working medium outlet 7, other implementations of this embodiment are the same as those of Embodiment 1. In this embodiment, the integrated design of the heat dissipation pipe 2 and the battery case body 1 omits the process steps of welding or pasting with conductive double-side...

Abstract

The invention discloses a battery case having a radiating tube. The battery case comprises a battery case body and the radiating tube having an inner chamber and fixed at the external side surface ofthe battery case body; and a condensation working medium is arranged in the inner chamber of the radiating tube. The invention also comprises a battery having the battery case provided by the invention. The condensation working medium in the inner chamber of the radiating tube can uniformize the heat generated in the battery and timely conducts the heat, so that the charge and discharge frequencyof the battery is increased, and the usage life of the battery is prolonged.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery external structure design, in particular to a battery case and a battery with heat dissipation pipes. Background technique [0002] Under the country's call and strong support, the new energy industry is developing rapidly in China, and the application of lithium batteries is becoming more and more popular, such as digital products, energy storage facilities, electric vehicles and household battery vehicles. What follows is that the market has higher and higher requirements for lithium battery products, such as: to use safer prismatic batteries, the service life of the batteries should be about 8 years, and the batteries must not have potential safety hazards. Lithium batteries have the advantages of high voltage, long life, high energy density, and portability, and their application fields are also expanding. Lithium batteries are also relatively harsh on the conditions of use, and t...
