Cold Plate Cooling Layout to Keep Air Out of the Pump Chamber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooling units experience a decrease in refrigerant amount and air ingress into the pump chamber, leading to reduced cooling efficiency.
Innovation Solution
The cooling unit design includes a tank chamber and a pump chamber positioned vertically, with the tank chamber's upper end higher than the pump chamber's, preventing air from entering the pump chamber and maintaining refrigerant circulation, thereby enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pump chamber is positioned at the same level as the tank chamber, then the device complexity is reduced, but air enters the pump chamber and cooling efficiency deteriorates
Solution Approach 1:
The patent applies vertical positioning of the pump chamber above the tank chamber, transitioning from horizontal to vertical spatial arrangement. This dimensional change uses gravity to prevent air from entering the pump chamber while maintaining effective refrigerant circulation, resolving the contradiction between reliability and device complexity.
2Reliability
If the refrigerant amount decreases, then the loss of substance occurs, but air enters the pump chamber and cooling efficiency deteriorates
Solution Approach 1:
The patent implements preliminary positioning of the pump chamber above the tank chamber before any refrigerant loss occurs. This pre-configured vertical arrangement ensures that even when refrigerant amount decreases over time, air cannot enter the pump chamber, thereby maintaining cooling efficiency despite substance loss.
3Reliability
If the pump chamber is positioned higher than the tank chamber, then air entry is prevented, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by positioning only the pump chamber above the tank chamber while allowing other components to be arranged flexibly. This localized vertical positioning prevents air entry into the pump chamber without requiring precise positioning of the entire device, reducing overall manufacturing precision requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively inhibits air entry into the pump chamber, maintaining refrigerant circulation and preventing deterioration in cooling efficiency, even when the refrigerant amount decreases.
Implementation Method 1
An upper end of the tank chamber in a first direction perpendicular to the horizontal direction is positioned higher than an upper end of the pump chamber in a first direction perpendicular to the horizontal direction

AI summary
A cooling unit includes a cold plate extending in a horizontal direction, a tank defining a tank chamber that stores a refrigerant, the tank including an outer tank surface and an inner tank surface, and a pump defining a pump chamber, the pump including an outer pump surface and an inner pump surface. The pump chamber is spaced away from and outside of the tank chamber. A portion of the outer tank surface and a portion of the outer pump surface are directly adjacent to one another in the horizontal direction. The pump chamber accommodates a rotating body that transfers the refrigerant. An upper end of the tank chamber in a first direction perpendicular to the horizontal direction is positioned higher than an upper end of the pump chamber in the first direction.
