Embodiment 1

[0050] see Figure 1-11 , the present invention provides a technical solution:

[0051] A ring-shaped heat-dissipating waterproof lithium battery pack assembly, including a connector 2, a battery pack 3, an isolation frame 4, a casing 5, and a wind bulb 6;

[0052] Wherein, the casing 5 includes an inner cylinder 502 and an outer cylinder 503, the bottoms of the inner cylinder 502 and the outer cylinder 503 are fixedly connected by an annular connecting plate 506, and an installation area is formed between the inner cylinder 502 and the outer cylinder 503, and the wind bulb 6 is installed on The center of the bottom of the annular connecting plate 506, and the inside of the wind ball 6 communicates with the inside of the inner tube 502; the outer side of the outer tube 503 is fixedly connected with the cooling tube 504 through the cooling connecting piece 505;

[0053] The battery pack 3 and the spacer 4 are both arranged in a ring structure; the battery pack 3 and the spacer...

Embodiment 2

[0071]When different from Embodiment 1, in order to adapt to various installation positions and situations, the wind bulb 6 is not directly installed on the bottom of the annular connecting plate 506 when installed, but is connected to the inner surface of the annular connecting plate 506 through a hose. The ring is connected; in this way, the best installation position of the wind balloon 6 can be flexibly adjusted, and the use is more convenient.

[0072] During implementation, the waterproof effect of the ring-shaped heat-dissipating waterproof lithium battery pack assembly of the present invention is tested through experiments, as shown in the following table:

[0073]

[0074] During implementation, the heat dissipation effect of the ring-shaped heat-dissipating waterproof lithium battery pack assembly of the present invention is detected by experiment. At first the present invention is applied on the battery car, and a thermometer is installed through the casing 5. The...

Abstract

The invention discloses an annular heat-dissipation waterproof lithium battery pack assembly which comprises a connector, a battery pack, an isolation frame, a shell and a wind ball, the shell comprises an inner cylinder and an outer cylinder, the bottoms of the inner cylinder and the outer cylinder are fixedly connected through an annular connecting plate, the air ball is installed in the center of the bottom of the annular connecting plate, and the interior of the air ball communicates with the interior of the inner cylinder; the outer side of the outer cylinder is fixedly connected with a heat dissipation cylinder through heat dissipation connecting pieces. A plurality of battery packs and isolation frames are arranged, and the plurality of battery packs are connected in series; and the battery pack and the isolation frame are mounted in a mounting area between the inner cylinder and the outer cylinder in a staggered manner. The battery pack is arranged to be of an annular structure, through cooperation of the shell and the wind ball, when the battery pack is used, the wind ball is subjected to external wind power, rotary air draft can be conducted, heat dissipation wind is formed, the heat dissipation effect of the shell is accelerated under the unpowered condition, and therefore the temperature of the battery pack is reduced; and the battery pack is sealed in the shell, so that the battery pack can be completely waterproof under the condition that the heat dissipation is not reduced.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an annular heat-dissipating and waterproof lithium battery pack assembly; in particular, a preparation process for the annular heat-dissipating and waterproof lithium battery pack assembly is also designed. Background technique [0002] A lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution, so this battery is also called a lithium metal battery. Unlike other batteries, Li-ion batteries have the characteristics of high charge density, long life and high unit cost. [0003] The combination of multiple lithium battery cells can form a higher voltage, which can be applied in various environments; such as lithium battery cars, battery cars, etc.; but many outdoor vehicles need to run for a long time, and the battery will emit a lot of heat ; and often encounter wind and rain, it...
