Solution Overview
Problem
Conventional fluid cooling devices suffer from heat conduction issues affecting the fluid pump, leading to component failure, and leakage due to gaps in the partially coupled structure between the fluid pump and heat sink, which requires a waterproof gasket that deteriorates over time.
Innovation Solution
A seamless-connection type fluid cooling device design where the endothermic cover and base are longitudinally attached with a coupling tube that plugs into a port, creating an insulation gap to prevent heat conduction and eliminate the need for a waterproof gasket, using a fully metal welded structure for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the fluid pump is partially coupled to the endothermic structure to isolate heat, then the heat conduction to the fluid pump is reduced, but a gap is created that causes fluid leakage requiring a waterproof gasket
Solution Approach 1:
A coupling tube is introduced as an intermediary component between the endothermic structure and the fluid pump. The coupling tube includes an insulating layer that mediates the connection, providing both mechanical coupling for fluid tightness and thermal insulation to prevent heat conduction to the fluid pump, thereby resolving the contradiction between heat isolation and leakage prevention.
2Reliability
If a waterproof gasket is added to the partially coupled structure to prevent leakage, then fluid leakage is prevented, but the gasket deteriorates over time leading to failure
Solution Approach 1:
The waterproof gasket is completely removed from the design. The coupling tube with its insulating layer provides inherent fluid tightness through its structural design, eliminating the need for separate waterproof gaskets that would deteriorate over time, thus extending the service life of the cooling device.
3Ease of manufacture
If the fluid pump is directly coupled to the endothermic structure for secure attachment, then assembly simplicity is achieved, but heat is conducted to the fluid pump causing component failure
Solution Approach 1:
The coupling tube integrates multiple functions into a single component: it provides mechanical coupling for secure attachment, thermal insulation to prevent heat conduction, and fluid tightness to prevent leakage. This merging of functions maintains assembly simplicity while preventing heat conduction to the fluid pump.
4Reliability
If a seamless connection is created between the coupling tube and endothermic structure, then waterproof gaskets are eliminated, but manufacturing precision requirements increase
Solution Approach 1:
The coupling tube is constructed as a composite structure with an insulating layer integrated into the coupling tube body. This composite design provides inherent fluid tightness and thermal insulation, reducing the need for high-precision sealing surfaces and gaskets, thereby balancing waterproof performance with manufacturing feasibility.

AI summary
A fluid cooling device includes an endothermic cover, an endothermic base and a fluid pump. The endothermic cover has a port; and a heat exchange chamber formed between the longitudinally affixed endothermic base and endothermic cover, and a heat exchange unit installed in the heat exchange chamber. The fluid pump includes a pump housing and a driving element, and the pump housing has a pump space and a coupling tube communicating to each other. A vane of a driving element is received in the pump space, and the coupling tube is longitudinally plugged into the port and seamlessly combined and fixed to each other, and the pump housing maintains an insulation gap with the endothermic cover through the coupling tube. Therefore, the heat of the heat sink will not be conducted to the fluid pump and no seam is produced and thus no waterproof gasket is needed.
