Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of thermodynamic machines, particularly the cold stage, is complex and costly due to the large number of mechanical parts and accessories required, which increases production costs and reduces reliability.
Innovation Solution
A thermodynamic machine design that integrates the compressor, expander, and fan within the cold stage using a single-piece base and cap enclosure, reducing the number of mechanical parts and simplifying assembly, while optimizing component placement and air circulation for improved heat exchange and acoustic attenuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple mechanical parts and accessories are used to assemble the cold stage components, then the components can be securely fixed and protected, but the assembly complexity increases, production cost increases, and reliability decreases
Solution Approach 1:
The patent merges multiple separate mechanical components (support plate, air guides, cover, and various fixing accessories) into a single integrated cold stage assembly. The base structure serves as both the support plate and housing, with components directly mounted or integrated into this single piece, eliminating the need for multiple separate parts and fixing accessories.
Solution Approach 2:
The base structure performs multiple functions simultaneously: it serves as the support plate for mounting components, as the housing enclosing the cold stage, as one of the air guide structures, and as the mounting surface for the cover. This multi-functionality reduces the total number of parts required.
2Ease of manufacture
If multiple mechanical parts and accessories are used in the assembly, then component fixation is improved, but the production cost increases due to the large number of parts
Solution Approach 1:
The patent combines multiple separate mechanical parts into a single integrated base structure. Instead of manufacturing separate support plates, air guides, and housings that require assembly with multiple fixing accessories, the design uses one base structure that incorporates all these functions, significantly reducing the total part count and associated manufacturing costs.
3Adaptability or versatility
If more components and accessories are added to the assembly, then functional completeness is improved, but the overall reliability deteriorates
Solution Approach 1:
The patent integrates all necessary functional components (support structure, air guiding, enclosure) into a single cold stage assembly, reducing the total number of separate parts. Fewer separate parts mean fewer potential failure points from connections, interfaces, and fixing accessories, thereby improving overall reliability while maintaining functional completeness.

Function Achieved in This Case
This design simplifies the assembly process, reduces production costs, and enhances the reliability of the thermodynamic machine by minimizing mechanical components and improving heat transfer efficiency and acoustic performance.
Implementation Method 1
the refrigerant circulates in the evaporator at low pressure... the fluid re-enters the evaporator to evaporate and heat up again
Implementation Method 2
The heat energy is largely exchanged by the fluid by means of phase changes by means of the latent energy of transformation associated with these phase changes
Implementation Method 3
At the outlet of the evaporator, a compressor compresses the fluid which circulates at high pressure in the condenser
Implementation Method 4
By heat exchange with the water in the tank in the condenser, the fluid cools and condenses
Implementation Method 5
The heat energy is largely exchanged by the fluid by means of phase changes by means of the latent energy of transformation associated with these phase changes
Implementation Method 6
before passing through a pressure reducer to lower its pressure
Implementation Method 7
The cold stage can also comprise a fan making it possible to force air circulation through the evaporator

AI summary
The invention relates to a thermodynamic machine assembly and can be particularly useful in a thermodynamic water-boiler. The thermodynamic machine includes a cold stage comprising a plurality of components (14, 15, 16, 20, 28) including an evaporator (14) through which a flow of air is established during the operation of the machine. According to the invention, the machine further comprises a base (25) and a cap (26) each forming a single-block part. Components (14, 20) of the cold stage are supported between the base (25) and the cap (26). The air flow is guided between the base (25) and the cap (26). The base (25) and the cap (26), together, seal the flow of air.
