1Weight of moving object
If the electronic device is miniaturized and made lightweight, then the portability and user comfort are improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The case is divided into two distinct sections: a heat absorption section made of ceramic material and a heat dissipation section made of metal alloy. This segmentation allows each section to perform its specific function optimally - the ceramic section absorbs heat from internal components while the metal section dissipates heat to the external environment, resolving the heat dissipation problem in miniaturized devices.
Solution Approach 2:
Different materials with different thermal properties are applied to different parts of the case. The heat absorption section uses ceramic material with high heat resistance and low thermal expansion coefficient, while the heat dissipation section uses metal alloy with high thermal conductivity. This local quality differentiation enables effective heat management in a compact design.
2Strength
If metal alloy material is used for the case, then the strength and appearance are improved, but the heat dissipation performance remains insufficient
Solution Approach 1:
The case employs a composite structure combining ceramic material and metal alloy material. The ceramic heat absorption section provides heat resistance and dimensional stability, while the metal heat dissipation section provides structural strength and thermal conductivity. This composite material approach achieves both mechanical strength and effective heat dissipation performance.
