Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a liquid evaporation cooling system is used for high-temperature components, then cooling efficiency for high-temperature components is improved, but components with low heat generation cannot be cooled effectively
Solution Approach 1:
The cooling system is divided into two separate circuits: a first circuit (evaporator, condenser, expansion device) for high-temperature components requiring evaporation cooling, and a second circuit (absorber, pump, expansion device) for low-temperature components requiring absorption cooling. This segmentation allows each circuit to be optimized for its specific temperature range and heat generation characteristics, resolving the contradiction between cooling efficiency for high-temperature components and adaptability for low-heat components.
Solution Approach 2:
The patent introduces a heat exchanger as an intermediary between the two cooling circuits. The heat exchanger enables thermal energy transfer from the first circuit to the second circuit, allowing the high-temperature cooling process to assist the low-temperature cooling process. This intermediary mechanism allows the system to effectively cool both high-temperature and low-heat components simultaneously.
2Productivity
If a compressor is used to circulate refrigerant in the cooling system, then refrigerant circulation is improved, but energy consumption increases
Solution Approach 1:
The patent replaces the traditional mechanical compressor with an absorption-based refrigerant circulation mechanism. Instead of using mechanical compression to circulate refrigerant, the system uses the absorption process where a absorbent material absorbs refrigerant vapor and releases it through thermal energy. This substitution eliminates the need for high-energy mechanical compression while maintaining effective refrigerant circulation, thereby reducing energy consumption while preserving productivity.

AI summary
A cooling apparatus for electric equipment includes a generator configured to receive a heat load from first electric components, a evaporator configured to receive a heat load from second electric components, a closed compartment enclosing the generator and evaporator, and a absorber transferring heat from heated fluid to the outside of the closed compartment. To obtain an efficient and reliable cooling apparatus, the cooling apparatus includes a first expansion device which reduces the pressure of the fluid, and forwards the fluid in a liquid state and with a lower pressure to the secondary cooling element, which transfers heat to the received fluid from the second electric components for evaporating the fluid.
