Problems solved by technology

This patent mainly solves the heat dissipation problem of super-large-capacity energy storage lithium-ion batteries, but it is not suitable for the temperature regulation of pure electric vehicle power battery packs, because the temperature difference that needs to be controlled by pure electric vehicle power battery packs is relatively high, not only for heat dissipation problem, it is also necessary to ensure that the temperature of the power battery pack is evenly distributed

Embodiment 1

[0032] Such as Figure 1 to Figure 8 As shown, this embodiment provides an air-cooling device for adjusting the temperature of the power battery pack of a pure electric vehicle, including a box body 2 and a box cover 1, the box shape is a cuboid, and the box cover 1 and box body 2 are connected by bolts and nuts to form a The battery box where the power battery pack is placed, six power battery packs 3 are arranged side by side in the box body 2, and each power battery pack 3 includes five layers of cooling plates 9 arranged from top to bottom, and the interval between two adjacent layers of cooling plates There are five battery modules 10 and four heat dissipation integrations 11. The heat conduction is enhanced by applying heat-conducting silica gel between the battery modules and the heat dissipation integration, and adhesive connection is used. The contact side of the battery module and heat dissipation integration with the heat dissipation plate is also It is coated with ...

Embodiment 2

[0040] Such as image 3 As shown, an air-cooling device for adjusting the temperature of a power battery pack of a pure electric vehicle has a structure as described in Embodiment 1, and the difference is that two sides of the box body 2 are provided with heat dissipation fins 7 opposite to each other. Two air inlets 8 and two air outlets 6 are oppositely arranged on two adjacent sides of the sheet 7 (ie, the other two sides of the box body 2 ).

Embodiment 3

[0042] An air cooling device for adjusting the temperature of the power battery pack of a pure electric vehicle, the structure is as described in Embodiment 1, the difference is that both the air inlet 8 and the exhaust port 6 are provided with internal threads (not shown in the figure). The air inlet and exhaust port can not only perform natural heat exchange, but also connect the pipe interface to use the air conditioning system for heat dissipation.

Abstract

The invention relates to an air cooling device capable of adjusting temperature of electromobile power battery packs and application thereof. The air cooling device comprises a box body and a box cover, the power battery packs are arranged in the box body, each power battery pack comprises multiple layers of cooling plates arranged from top to bottom, a battery module and a cooling assembly are arranged between each two layers of the cooling plates at an interval, multiple temperature sensors are arranged on each cooling plate, and an air inlet and an air outlet are arranged on opposite side faces of the box body. Compared with conventional power battery cooling devices, the air cooling device is reasonable in structural design and convenient to mount and use. The air cooling device has better cooling effect, so that cooling efficiency of the power battery packs can be greatly improved; reasonable temperature control of the power battery packs can be realized, so that influence on service life and using effect of the power battery packs caused by the fact that the power battery packs are too high in temperature locally is avoided. In addition, the air cooling device can be matched with an air conditioning management system of an automobile for use, thereby having various using modes.

Description

technical field [0001] The invention relates to an air cooling device for adjusting the temperature of a power battery pack of a pure electric vehicle and an application thereof, belonging to the technical field of battery heat management. Background technique [0002] With the development of social economy, energy and environmental problems are becoming more and more serious. As an effective way to solve these problems, pure electric vehicles have ushered in unprecedented development opportunities. At present, the power battery has become the main component that restricts the development of pure electric vehicles, and the development level of power battery thermal management technology has a great impact on the service life and use effect of the power battery. The thermal management technology of pure electric vehicle power battery mainly includes the heat dissipation technology of power battery and the balance technology of heat dissipation. The existing heat dissipation ...
