Problems solved by technology

However, when the battery is discharged at a high rate, the temperature can exceed 70 degrees, which greatly exceeds the optimal operating temperature of the battery. It is necessary to efficiently dissipate heat from the battery, and the cylindrical battery has a special shape. Electric vehicles have problems with the volume, weight, and temperature balance of the cooling system. Strict requirements, the design of heat dissipation device is very difficult

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The invention discloses a cylindrical battery cooling system, which can provide a cooling effect for charging and discharging high-power batteries of electric vehicles, and achieve efficient heat dissipation of multi-layer cylindrical batteries through the combination of the invention , maintaining the balance of battery temperature distribution.

[0025] combine figure 1 , Let's take the 18650 battery as an example, the height H of the battery is 65mm, and the diameter D is 18mm. The arc-shaped outer surface of the cylindrical battery 30 makes it difficult to transfer heat to the outside through conduction.

[0026] The cylindrical battery cooling system of the present invention is composed of several single-row battery cooling devices, and the specific configuration will be described in detail below. The single-row battery cooling device inc...

Abstract

The invention discloses a cylindrical battery cooling system, which relates to the technical field of battery cooling devices; it is composed of several single-row battery cooling devices, the single-row battery cooling device includes cooling pipes and battery brackets, and the cooling pipe has a The hollow channel is used for the circulation of the cooling liquid. The cooling pipe has a bar-shaped embedding groove on at least one of the two outer walls of the hollow channel; the battery holder has a The concave arc surface, the rear part of the battery bracket has a bump, and the bumps of multiple battery brackets can be snapped into the strip-shaped embedding grooves of the above-mentioned cooling pipes; the beneficial effects of the present invention are: the high-efficiency The coolant maintains the balance of battery temperature distribution, can provide cooling effect for charging and discharging high-power batteries of electric vehicles, and realize efficient cooling of cylindrical batteries.

Description

technical field [0001] The invention relates to a battery cooling device, and in more detail, the invention relates to a cylindrical battery cooling system. Background technique [0002] Cylindrical batteries are widely used to power household appliances, notebook computers, and various handheld devices, and their huge sales make their cost performance far exceed that of prismatic batteries. With the development of electric vehicles, more and more cylindrical batteries are used in electric vehicle battery packs. However, when the battery is discharged at a high rate, the temperature can exceed 70 degrees, which greatly exceeds the optimal operating temperature of the battery. It is necessary to efficiently dissipate heat from the battery, and the cylindrical battery has a special shape. Electric vehicles have problems with the volume, weight, and temperature balance of the cooling system. Strict requirements make the design of heat dissipation device very difficult. Conte...
