Server Cooling System With Movable Cover and Lateral Condenser

Solution Overview

Problem

In existing server cooling systems, maintenance is hindered by the need to remove the condenser for access, leading to inefficient condensation of vapor coolant and potential leakage, and placement of the condenser off-center reduces condensation efficiency.

Innovation Solution

A cooling system with a lateral condenser and a movable cover that forms an airtight space, allowing the condenser to be positioned directly above the vapor coolant for enhanced condensation efficiency while allowing maintenance access without blocking the heat source.

Solution Approach 1:

The condensation function is segmented into two independent condensers: a first condenser positioned above the liquid coolant level for maintenance access, and a second condenser positioned above the vapor coolant region for optimal condensation efficiency. Each condenser handles a portion of the condensation task, allowing both maintenance access and effective condensation to coexist.

Inventive Principle:

Solution Approach 2:

The condensation function is distributed across different spatial dimensions - the first condenser operates in the liquid level region while the second condenser operates in the vapor coolant region above. This dimensional distribution allows both condensers to perform their functions simultaneously without interfering with maintenance access.
