Solution Overview
Problem
Conventional compressor-evaporation tray arrangements face challenges in achieving intimate contact and efficient heat transfer due to variable compressor housing dimensions, leading to inefficient evaporation rates, especially when the water level is low, and require specialized trays for different compressor models.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible base is used to accommodate variable compressor dimensions, then adaptability is improved, but heat transfer efficiency deteriorates due to folding and air gaps
Solution Approach 1:
The evaporation tray utilizes a flexible membrane base that can elastically deform to conform to different compressor housing shapes and surface irregularities, ensuring continuous contact without folds or air gaps while maintaining thermal conductivity
Solution Approach 2:
The patent changes the physical parameters of the base material by using an elastomeric compound with specific elasticity and thermal conductivity properties, allowing the base to adapt its shape while maintaining thermal contact efficiency across varying water levels and compressor geometries
2Strength
If a strong bottom with inherent rigidity is used, then structural strength is improved, but contact area with compressor housing deteriorates when water pressure is low
Solution Approach 1:
The base is designed as a flexible membrane that can deform under minimal pressure to achieve full contact with the compressor housing surface, eliminating the need for rigid structures while maintaining structural integrity through the elastomeric material properties

Implementation Method 1
an elastomeric evaporation tray (5) formed in one piece from a rubber-elastic plastic material... the base (6) is stretched over the upper shell (3) and fits snugly everywhere on the convex curvature thereof
Implementation Method 2
evaporate water, which condenses on an evaporator in the interior of the refrigeration device, with the aid of heat loss given off by the compressor during operation... Good heat transfer from the compressor to the water in the evaporation tray is essential for efficient evaporation

AI summary
The arrangement has an evaporation shell (5) with a ductile and flexibly thin base (6), where the evaporation shell is mounted on a cylindrical lower shell (2) and a dome-shaped upper shell (3) of a compressor (1). The base sectionally lies on the dome-shaped upper shell of the compressor under prestress. The base is made of elastomeric material, where the evaporation shell is made as a single piece from the elastomeric material. The evaporation shell includes a cylindrical outer wall (8) and an inner wall (10), where the outer wall protrudes from a ring (7).
