Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing diffusion-absorption cycle cooling apparatuses are space-consuming due to their dimensions, making them impractical for certain applications.
Innovation Solution
The apparatus is designed with the absorber positioned above the evaporator, and the inert gas is heavier than the refrigerant, allowing for more compact dimensions while maintaining performance, utilizing a bubble pump and specific fluid circulation to facilitate efficient heat dissipation without mechanical pumps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the apparatus is designed with conventional dimensions and arrangement, then the diffusion-absorption cycle can function, but the apparatus becomes space-consuming and difficult to utilize in various applications
Solution Approach 1:
The patent applies vertical arrangement of components along the height direction rather than horizontal spreading. The absorber is positioned at a higher level than the evaporator, utilizing the vertical dimension to reduce the horizontal footprint and overall volume of the apparatus, making it more adaptable to various applications with space constraints.
Solution Approach 2:
The patent changes the density parameter relationship between the inert gas and refrigerant, selecting an inert gas that is heavier than the refrigerant. This parameter change enables the heavier inert gas to settle at the bottom and the lighter refrigerant to rise, facilitating natural circulation and compact apparatus design without requiring additional pumping equipment.
2Volume of stationary object
If the absorber is arranged at a higher level than the evaporator with heavier inert gas, then compact dimensions are achieved, but the fluid circulation must rely on density-driven natural convection
Solution Approach 1:
The apparatus utilizes natural convection driven by density differences between the inert gas and refrigerant to achieve self-circulation. The heavier inert gas naturally settles at the bottom while the lighter refrigerant rises, creating automatic fluid circulation without requiring mechanical pumps or complex control systems, thus simplifying the device while achieving compact dimensions.

AI summary
The invention relates to an apparatus (1) comprising a generator (5), an evaporator (6), an absorber (8) and a condenser (9) circulating a refrigerant (R), an inert (I) and an absorbent (A) in a diffusion-absorption cycle. The generator (5) and the evaporator (6) are arranged in an electric cabinet (2) to receive a heat load from primary electric components (3) and secondary electric components (4). The absorber (8) and the condenser (9) are arranged outside of the electric cabinet (2) and at a higher level than the evaporator (6) to receive fluid from the generator (5) and the evaporator (6) and for dissipating heat from the received fluid to the surrounding environment. The inert (I) and refrigerant (R) are selected such that the inert (I) is heavier than the refrigerant (R) in order to obtain fluid circulation where the inert (I) exiting the absorber (8) flows downwards to the evaporator (6) and the inert (I) exiting the evaporator (6) flows upwards to the absorber (8).
