AI Technical Summary

Technical Problem

Existing automotive wiring harness protection boxes are prone to overheating at connection points, leading to short circuit risks, and have poor internal ventilation, making effective heat dissipation impossible.

Method used

Design a protective box for automotive wiring harnesses. It adopts an active air intake and exhaust method, using intake and exhaust fans to control the airflow to spiral within the installation space. Combined with a filter screen to filter impurities, and divided into independent spaces by ribs, it achieves active heat dissipation and impurity isolation.

Benefits of technology

It achieves efficient heat dissipation, avoids overheating at wire harness connection points, reduces the risk of short circuits, and keeps the installation space clean, thereby improving the safety and reliability of the protective box.

Abstract

The application discloses a protective box for automobile wire harness, and relates to the technical field of protective boxes, which comprises a bottom box and a top box, one end of the bottom box is provided with a supporting box, and the opening of the bottom box and the top box is divided into multiple installation spaces by a rib plate; multiple air inlet channels and multiple air inlet pipes arranged in the corresponding installation spaces are arranged in the bottom box, and the top box is provided with multiple air outlet channels and multiple air outlet pipes arranged in the corresponding installation spaces; an air inlet fan and an air outlet fan are arranged in the supporting box, the air inlet fan is communicated with the multiple air inlet channels, and the air outlet fan is communicated with the multiple air outlet channels. The application accelerates the air flow in the mode of active air intake and active air exhaust, controls the flow direction of the gas in the installation space, makes the gas realize spiral flow in the installation space, avoids the turbulent flow of the air flow, and quickly takes away the heat of the wire harness in the process of accelerated flow of the gas. Through the continuously entering cold air, the heat accumulation in the installation space is effectively avoided, and high-efficiency heat dissipation is finally achieved.
