Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing outdoor units of air conditioners face challenges in effectively cooling heating units and improving heat exchange efficiency due to limited contact area between refrigerant pipes and heat radiating members, which can lead to reduced performance and potential damage during manufacturing.
Innovation Solution
The outdoor unit incorporates a cooling unit with a heat radiating member that directly contacts the heating unit and a refrigerant pipe extended through the heat radiating member, increasing the contact area for enhanced heat exchange efficiency, and a manufacturing method involving a molten metal injection process with a guide pin to prevent refrigerant pipe deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the refrigerant pipe is simply inserted into the heat radiating member without extended contact, then the manufacturing process is simple, but the heat exchange efficiency is insufficient
Solution Approach 1:
The refrigerant pipe is nested within the heat radiating member, with the pipe extending through the interior space of the radiating member. This nested configuration maximizes the contact surface area between the refrigerant pipe and the heat radiating member, thereby improving heat exchange efficiency while maintaining a compact structure.
2Loss of energy
If the refrigerant pipe is extended through the heat radiating member to increase contact area, then heat exchange efficiency improves, but the refrigerant pipe may be damaged during manufacturing
Solution Approach 1:
The refrigerant pipe is pre-positioned and fixed within the heat radiating member before the manufacturing process begins. This preliminary positioning ensures that the pipe remains stable and protected during subsequent manufacturing steps, preventing deformation or damage while enabling the extended contact configuration for improved heat exchange.
3Ease of manufacture
If the cooling unit structure is simplified, then manufacturing cost is reduced, but the cooling performance of the heating unit deteriorates
Solution Approach 1:
The cooling unit merges the heat radiating member and the refrigerant pipe into an integrated assembly where the pipe extends through the radiating member. This combined structure achieves enhanced cooling performance through increased heat exchange contact area while maintaining manufacturing simplicity by reducing the need for separate complex components and assembly steps.
