Solution Overview
Problem
Existing immersion cooling systems face challenges in balancing operating costs and heat dissipation performance due to limited flow rates and high viscosity of cooling liquids, leading to insufficient cooling capacity and increased energy consumption when using high-speed pumps.
Innovation Solution
The system incorporates a pressure seal tank with a blower and distributor plate to enhance gas circulation, forming uniform bubbles that increase the fluidity of the cooling liquid, thereby improving heat dissipation without increasing energy costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a highspeed or large-capacity pump device is used to increase the fluidity of the cooling liquid, then the cooling capacity is improved, but the operating costs and energy consumption increase
Solution Approach 1:
The patent replaces the traditional pump-driven mechanical circulation system with a gas circulation system. Gas is injected into the pressure seal tank to create gas-liquid two-phase flow, which naturally drives the cooling liquid circulation without requiring high-power pump devices, thus reducing energy consumption while maintaining cooling capacity
Solution Approach 2:
The patent introduces gas injection into the cooling liquid system to create pneumatic-hydraulic interaction. The gas bubbles rise through the cooling liquid, creating upward flow and convection currents that enhance fluidity and heat transfer efficiency without mechanical pumping
2Temperature
If the flow area for cooling liquid is increased, then the cooling capacity is improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent changes the physical state parameters of the cooling system by introducing gas phase into the liquid cooling system. This creates a two-phase flow system where gas bubbles dispersed in the cooling liquid significantly enhance heat transfer coefficients and fluidity without requiring larger flow areas or more complex piping structures
