AI Technical Summary

Technical Problem

Existing battery pack cooling devices improve performance by increasing the number of heat exchange fin layers, resulting in excessively large cooler sizes that are difficult to install. At the same time, valve body vibration and noise affect the user experience, and the cooling performance is reduced due to cabin heat radiation, increasing energy consumption.

Method used

The system employs a herringbone heat exchange channel and a combination of insulation sponge and vibration damping unit. The insulation sponge isolates heat from the cabin, the vibration damping unit reduces vibration noise, and the herringbone channel improves heat exchange performance by absorbing heat through refrigerant evaporation.

Benefits of technology

It effectively avoids heat radiation from the cabin, reduces vibration and noise, improves cooling performance, reduces energy consumption, and increases the battery pack's driving range.

Abstract

The utility model discloses a battery pack cooling device of hybrid vehicle type relates to power battery pack field. The battery pack cooling device of hybrid vehicle type, including board change body, water inlet pipe, water outlet pipe, valve body, heat preservation sponge, damping unit and heat exchange unit heat exchange plate unit. The battery pack cooling device of hybrid vehicle type sets up heat preservation sponge and insulates heat exchange unit heat exchange plate unit, effectively avoids the heat radiation of cabin to the board change body of cooling device, under the action of damping unit, supports the board change body, and the board change body is damped, and then the heat insulation is carried out with heat preservation sponge, and the heat radiation of cabin is avoided to the board change body, and water inlet pipe and water outlet pipe cooperate battery pack cooling circuit, make the cooling liquid enter heat exchange unit heat exchange plate unit, and then pass through the evaporation of refrigerant to absorb the heat of battery pack cooling liquid, thereby cooling battery pack.
