Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional immersion cooling systems are difficult to install and move due to their requirement for external connections to cooling towers or chillers, limiting their mobility and self-containment.
Innovation Solution
A self-contained single-phase immersion cooling system is designed with a cabinet, partition board, circulation pipeline, driving mechanism, and cooling mechanism, allowing for closed-loop cooling without external connections, featuring a circulation pipeline with input, output, and cooling segments, and a fan-based cooling mechanism for air heat exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional immersion cooling systems are connected to external cooling towers or chillers, then cooling effectiveness is improved, but installation difficulty and immobility increase
Solution Approach 1:
The patent merges the cooling function directly into the cabinet by integrating a cooling mechanism (compressor, condenser, evaporator) within the cabinet structure. This combines the immersion tank and cooling system into a single self-contained unit, eliminating the need for external cooling towers or chillers while maintaining effective cooling capability.
Solution Approach 2:
The cabinet serves multiple functions: it houses both the immersion tank for heat absorption and the cooling mechanism for heat rejection. This multi-functional design allows the system to operate independently without requiring separate external cooling infrastructure, thereby improving installation ease and mobility.
2Ease of operation
If a self-contained cooling system is designed within the cabinet, then ease of installation and mobility are improved, but the system complexity increases
Solution Approach 1:
The cooling mechanism components (compressor, condenser, evaporator, refrigerant pipes) are nested within the cabinet structure in a compact arrangement. The evaporator is positioned to contact the immersion tank bottom, the refrigerant circulation path is integrated within the cabinet, and the fan is mounted on the cabinet side, creating a space-efficient nested configuration that manages complexity through organized integration.

Function Achieved in This Case
Enables independent operation, easier installation, and mobility by facilitating closed-loop cooling within a compact, self-contained unit, eliminating the need for external cooling systems.
Implementation Method 1
an electronic device, for example a host computer and a server, generates a large amount of heat during operation; thus, unless the heat is dissipated or the electronic device is cooled
Implementation Method 2
Removal of heat from an electronic device with a cooling liquid has the advantages of speedy heat transfer, quick convection and high specific heat capacity
Implementation Method 3
a cooling mechanism disposed on a side of the cabinet and positioned proximate to the cooling space, wherein a ventilation opening in communication with the cooling space is formed on at least one lateral side of the cabinet

AI summary
A single-phase immersion cooling system includes a cabinet, circulation pipeline, driving mechanism and cooling mechanism. The cabinet has therein a partition board for partitioning a space into an immersion tank and cooling space. The circulation pipeline includes an input segment, output segment and cooling segment. The input and output segments penetrate the partition board. The cooling segment is disposed in the cooling space and is in communication with the input and output segments. The driving mechanism is disposed at the cooling segment. The cooling mechanism is disposed on one side of the cabinet and positioned proximate to the cooling space. A ventilation opening in communication with the cooling space is formed on at least one lateral side of the cabinet. The single-phase immersion cooling system operates independently without connecting to any external cooling tower or chiller, so it is easier to install and move this system.
