AI Technical Summary

Technical Problem

In the current new energy vehicle electronic control heat dissipation type soft connection structure, the flexible insulating sleeve is prone to cracking during use, which leads to reduced heat conduction efficiency and contamination of surrounding components.

Method used

By employing a multi-layered physical barrier and dynamic constraint approach, and combining anti-overflow components and limiting components, thermal grease overflow is prevented. These components include a first baffle, a second baffle, a third baffle, an L-shaped block, and a fourth baffle. Together with silicone pads and heat dissipation grooves, they achieve comprehensive control over the thermal grease.

Benefits of technology

Without the need for sealant, it effectively prevents thermal grease from overflowing, improves heat dissipation performance and overall structural stability, and avoids cracking of the flexible insulating sleeve.
