Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing heat exchanger designs are used, then the structure is simple, but the overall size is large and heat exchange efficiency is low
Solution Approach 1:
The heat exchange core is divided into multiple independent channels (first heat exchange channel, second heat exchange channel, etc.), each with separate inlet and outlet channels. This segmentation increases the total heat exchange surface area and improves heat dissipation efficiency while maintaining a compact overall structure.
Solution Approach 2:
The patent utilizes the internal three-dimensional space of the housing by arranging heat exchange channels in multiple layers and directions. The communication channels connect different levels of the heat exchange core, effectively using vertical and horizontal dimensions to maximize heat exchange surface area within a limited volume.
2Productivity
If existing heat exchanger designs are used, then the structure is simple, but the heat dissipation efficiency cannot satisfy compact electronic devices
Solution Approach 1:
The communication channels are integrated directly into the housing structure rather than being separate external components. The housing serves dual functions as both the structural enclosure and the heat exchange conduit, eliminating the need for additional connection tubes and reducing overall structural complexity despite the enhanced heat dissipation capability.
Solution Approach 2:
The housing is designed to perform multiple functions: it provides structural enclosure, serves as a heat exchange channel, and acts as a mounting structure for the heat exchange core. This multi-functionality reduces the number of separate components needed, maintaining simplicity while improving heat dissipation efficiency.
3Productivity
If communication channels are added inside the housing, then heat exchange efficiency improves, but manufacturing complexity increases
Solution Approach 1:
The communication channels are formed as integral parts of the housing structure during the housing manufacturing process. By combining the housing and communication channel fabrication into a single manufacturing step (such as injection molding or CNC machining), the patent avoids the need for separate assembly operations, thereby maintaining ease of manufacture despite the enhanced heat exchange functionality.

AI summary
A heat exchanger includes a heat exchange core arranged inside the housing, and a side of the housing is provided with an air vent. The heat exchanger is provided with a communication channel in communication with the air vent. The communication channel is located inside the housing, and is located at a side in the housing opposite to the air vent. In the heat exchanger, the air vent is in communication with the communication channel inside the housing, and the communication channel is located at the side in the housing opposite to the air vent, such that the internal space of the housing is fully utilized. Compared to the prior art, the overall size of the heat exchanger is reduced, and the cost for the heat exchanger is reduced.
