Solution Overview
Problem
Existing container structures for computing devices rely on open heat dissipation methods that expose the devices to outside air, leading to instability and operational failures due to temperature, humidity, dust, and corrosive gases.
Innovation Solution
A closed-loop system within the container structure utilizing a heat exchanger and internal air circulation, where a cold air channel, hot air channel, and heat exchange channel are integrated to circulate and exchange air internally, reducing reliance on outside air for heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If open heat dissipation manner is used with outside air entering the container structure, then heat dissipation function is achieved, but the computing device is affected by outside air (temperature, humidity, dust, corrosive gases) causing operational instability
Solution Approach 1:
The patent creates a closed-loop air circulation system that isolates the computing device from the external environment. The air channel forms a sealed circulation path with the heat exchanger, preventing outside air containing dust and corrosive gases from entering the container structure, while still achieving heat dissipation through internal air circulation and heat exchange.
Solution Approach 2:
The heat exchanger acts as an intermediary component between the internal air channel and the external environment. It enables heat transfer from the hot air channel to the cold air channel without requiring direct contact with outside air, thus achieving heat dissipation while maintaining environmental isolation.
2Reliability
If closed-loop internal air circulation is implemented, then protection from outside air is achieved, but heat dissipation efficiency may be reduced
Solution Approach 1:
The patent implements a continuous air circulation system where air constantly flows through the cold air channel, passes over the heat exchanger, moves through the hot air channel, and returns to the heat exchanger. This continuous circulation ensures sustained heat dissipation efficiency while maintaining the closed-loop protection from outside air.
Solution Approach 2:
The system uses its own internal air for heat dissipation rather than relying on external air. The air within the closed-loop system serves dual purposes: it absorbs heat from the computing device and is cooled by the heat exchanger, creating a self-sustaining heat dissipation cycle that does not compromise operational stability.
