Solution Overview
Problem
Existing refrigeration systems for high-performance devices, such as servers, are complex and require separate liquid cooling and air cooling systems, leading to increased floor area and installation challenges in narrow spaces.
Innovation Solution
An integrated refrigeration apparatus that combines liquid cooling and air cooling systems into a single module, with a dry cooler and heat exchange core sharing an external air heat exchange channel, allowing for simplified installation and reduced space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If liquid cooling and air cooling are provided separately in corresponding racks, then the refrigeration function is reliable, but the device complexity increases and floor area increases
Solution Approach 1:
The patent combines the liquid cooling system and air cooling system into a single integrated refrigeration apparatus. The liquid cooling system includes a liquid cooling unit with evaporator and condenser, while the air cooling system includes an air cooling unit with heat exchange core. Both systems share common components such as the compressor, expansion valve, and outdoor air inlet/outlet channels, forming one unified device that provides both cooling modes without requiring separate racks or independent systems.

3Device complexity
If dry cooler and heat exchange core share one external air heat exchange channel, then the structure is simplified and manufacturing costs are reduced, but the heat exchange efficiency may be affected
Solution Approach 1:
The patent divides the external air heat exchange channel into distinct segments: one channel path for the dry cooler and another channel path for the heat exchange core. Although both share the same outdoor air inlet and outlet, the internal flow paths are separated, allowing independent heat exchange operations. This segmentation maintains heat exchange efficiency while simplifying the overall structure by sharing common external interfaces.
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
The integrated system simplifies the refrigeration process, reduces installation area, and lowers manufacturing costs, making it suitable for installation in narrow areas while effectively cooling devices by sharing a common external air heat exchange channel.
Implementation Method 1
The liquid cooling system at least includes a dry cooler and a liquid supply and return pipe connected in series with the dry cooler, where the dry cooler is positioned between the outdoor air inlet and the outdoor air outlet
Implementation Method 2
the evaporator is positioned at the operating air outlet to allow hot air entering via the operating air inlet to exchange heat through the evaporator and to be discharged through the operating air outlet
Implementation Method 3
the condenser is positioned between the outdoor air inlet and the outdoor air outlet
