AI Technical Summary

Technical Problem

In existing lithium battery cooling equipment for new energy vehicles, manual cleaning is difficult to guarantee in a timely manner, and dust and particulate matter in the environment can easily adhere to the exposed cooling system after the vehicle stops, leading to blockage and reduced cooling efficiency.

Method used

A self-cleaning component was designed, including a self-cleaning scraper ring, a filter screen, a power storage component, a delay component, and a cleaning nozzle. Through the cooperation of a pulse air pump, a guide groove, and a one-way valve, it achieves automatic cleaning and dust prevention functions, ensuring timely cleaning and preventing dust from entering.

Benefits of technology

It achieves automatic cleaning without human intervention, ensuring that the lithium battery operates within the optimal temperature range, extending battery life, reducing dust accumulation, and ensuring the long-term stability of the heat dissipation system.

Abstract

The application discloses a new energy automobile lithium battery heat dissipation device, and relates to the technical field of new energy battery boxes, which comprises a battery box, a negative pressure fan fixedly connected to one side of the battery box, an air inlet channel arranged on the surface cover of the negative pressure fan and fixedly connected with the battery box, and a PLC controller fixedly connected to the other side of the battery box; and a self-cleaning assembly comprising a self-cleaning scraping ring slidingly connected to one side of the air inlet channel, a conversion piece arranged on one side of the self-cleaning scraping ring, and a filter screen plate arranged on the other side of the self-cleaning scraping ring. The power storage element stores power, and when the filter screen plate is blocked to a certain degree, the cleaning process is automatically triggered. The backflushing dust cleaning is realized by cooperation of the cleaning spray head and the pulse air pump, dust is automatically discharged through the guide groove and the one-way valve, thus manual intervention is not needed, the labor cost is saved, the cleaning is ensured to be timely, and the heat dissipation efficiency caused by blockage is avoided.
