AI Technical Summary

Technical Problem

Traditional water-cooled quick-connect couplings in liquid cooling systems face issues such as loosening under vibration, potential gaps at the joint interface, and leakage risks due to insufficient vibration resistance and localized contact in threaded or snap-fit connections.

Method used

A water-cooled quick connector utilizing a temperature difference assembly method to create an interference-fit section between the connector end and seat, forming a radial heat-shrink fit after assembly, ensuring a stable mechanical restraint without threads or snaps, and reducing the risk of leakage.

Benefits of technology

The interference-fit section provides a stable connection with reduced leakage risks and improved structural durability under vibration, enhancing sealing reliability and connection strength.

Abstract

A water-cooled quick-connect coupling includes a connector end and a connector seat. The connector end has a mating portion, and the connector seat has a mating hole corresponding to the mating portion. The mating portion is fitted into the mating hole, and the two form an axially extending interference-fit section. This interference-fit section is assembled by temperature difference to form an interference fit (interference fit or tight fit), thereby forming a tight joint interface, which greatly improves the anti-loosening and anti-leakage performance, and is suitable for fluid connection in liquid cooling systems.
