AI Technical Summary

Technical Problem

In existing water-cooling systems, water-cooling connectors are prone to leakage and it is difficult to simultaneously achieve a tight connection between connectors and an effective reduction in fluid resistance.

Method used

A plug and coupling assembly is designed, comprising a piston with a conical surface and an extension, a plug body with an annular hook and a locking groove, and a label ring and a rubber ring to ensure that the plug and the pipe seat are tightly engaged, and to reduce fluid resistance through the conical surface and extension of the piston.

Benefits of technology

This design achieves a tight fit between the tube seat and the tube plug, reducing resistance to fluid flow, improving heat dissipation efficiency, preventing fluid overflow, and ensuring that the tube plug is not easily dislodged.

Abstract

A pipe plug and coupling assembly, the pipe plug has a cavity and a front opening and a rear opening at opposite ends of the cavity. The pipe plug comprises a pipe plug body, a pipe plug rear end and a piston. The pipe plug body comprises a ring-shaped hook protruding from an outer surface of the pipe plug body. The front opening defines a front end surface of the pipe plug body. The pipe plug rear end is connected to the pipe plug body. The rear opening is at an end of the pipe plug rear end away from the pipe plug body. The piston is disposed in the cavity. The piston comprises a piston body, a plug head and at least three extensions. The piston body has a tapered surface. The plug head is disposed on the piston body. The at least three extensions are connected to the tapered surface of the piston body. The at least three extensions extend away from the plug head from the tapered surface of the piston body. A gap is defined between the at least three extensions at a side of the piston body away from the plug head. The pipe plug and coupling assembly of the present disclosure can reduce the resistance of fluid flowing through the pipe seat and the pipe plug, thereby improving the heat dissipation efficiency.
