Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air cooling technologies using heat sink fins are used, then the structure is simple and easy to manufacture, but the heat dissipation capability is insufficient for high-speed network transmissions exceeding 800 G
Solution Approach 1:
The patent applies hydraulics by introducing a liquid cooling system where a cooling fluid circulates through channels in contact with the transceiver module. The fluid circulation drive member pumps the cooling fluid through the cooling fluid channel, enabling efficient heat transfer from the transceiver module to the cooling fluid, thereby resolving the insufficient heat dissipation capability of air cooling systems.
Solution Approach 2:
The cooling fluid acts as an intermediary between the transceiver module and the heat sink fin. The cooling fluid channel is arranged between the heat sink fin and the transceiver module, allowing heat to be transferred from the transceiver module to the cooling fluid, which then carries the heat to the heat sink fin for dissipation, thus improving heat dissipation capability while maintaining structural simplicity.
2Productivity
If transmission capability of transceiver module is increased from 800 G to 1.6 T or 3.2 T, then data transmission performance is improved, but heat generated by the transceiver module increases significantly exceeding 30 W
Solution Approach 1:
The patent employs a liquid cooling system with a cooling fluid circulation loop to handle the significant heat generation from high-speed transmission. The fluid circulation drive member actively circulates cooling fluid through the cooling fluid channel in contact with the transceiver module, providing sufficient heat dissipation capability to support transmission rates of 1.6 T and 3.2 T.
Solution Approach 2:
The patent changes the cooling parameter from air cooling to liquid cooling by introducing a cooling fluid with higher heat capacity. This parameter change enables the system to handle the increased heat generation from high-speed transmission effectively, as the cooling fluid can absorb and transport more heat compared to air cooling systems.

AI summary
A cooling system is adapted to a communication apparatus. The cooling system includes heat sink fins, a cooling fluid channel, and a cooling fluid drive module. The cooling fluid channel is arranged between the heat sink fins and the transceiver modules. The cooling fluid drive module supplies cooling fluid, allowing the cooling fluid to flow through the cooling fluid channel to cool the transceiver modules. This resolves the issue of excessive heat generated during the operation of the transceiver modules.
