Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If heat pipes or vapor chambers are used for heat dissipation, then heat transfer effect is improved, but heat exchange efficiency deteriorates due to limited heat spreading capability
Solution Approach 1:
The heat dissipation element is divided into multiple independent chambers (first chamber, second chamber, third chamber) that can independently handle heat dissipation tasks. Each chamber can be filled with different working fluids optimized for specific functions, allowing simultaneous heat spreading and remote heat dissipation without compromising overall efficiency
Solution Approach 2:
The patent employs a nested structure where the pipe containing the second working fluid is positioned within or adjacent to the first housing containing the first working fluid. This nested arrangement allows heat to be transferred from the heat source through multiple working fluids in sequence, achieving both heat spreading and remote dissipation while maintaining compact form factor and high efficiency
2Length of moving object
If heat pipes are used for remote heat dissipation, then heat dissipation at remote distance is achieved, but manufacturing cost increases
Solution Approach 1:
The heat dissipation element utilizes capillary wick structures that automatically transport condensed working fluid back to the evaporation region without requiring external pumps or complex control systems. This self-service mechanism eliminates additional components and reduces manufacturing complexity while achieving remote heat dissipation
Solution Approach 2:
The invention relies on the phase transition (evaporation and condensation) of working fluids to transfer heat over distances. By filling chambers with appropriate working fluids and utilizing natural phase change cycles driven by temperature differences, the system achieves remote heat dissipation through simple, cost-effective means without complex mechanical systems
3Area of stationary object
If vapor chambers are used for heat spreading, then in-plane heat spreading is improved, but heat dissipation efficiency at remote distances deteriorates
Solution Approach 1:
The patent introduces a pipe containing a second working fluid as an intermediary element between the heat source region (first chamber) and the remote dissipation region (third chamber). This intermediary facilitates efficient heat transfer over distance by utilizing phase change of the second working fluid, while the first chamber simultaneously provides heat spreading function, thus resolving the contradiction between heat spreading area and remote heat dissipation efficiency

Implementation Method 2
One side of the heat pipe absorbs heat produced by the heat-generating elements and then evaporated

AI summary
A heat dissipation element includes a first and a second housing, and a first and a second working fluid. The first housing has a first inner space. At least one pipe is formed on one side of the first housing and has a second inner space. The first and the second inner space are communicable and together define a first chamber. The second housing has a second chamber. A first and a second working fluid is, respectively, provided in the first and the second chamber. One side of the second housing is fixedly connected to one end of the pipe. The first and the second chamber are incommunicable. With these arrangements, the heat dissipation element not only can provide better heat spreading and heat transfer effect, but also can be produced at largely lower manufacturing costs.
