Description

Technical Field

[0001] The present application relates to the field of heat transfer and heat conduction equipment, and in particular to a heat sink for use outside a ship cabin. Background Art

[0002] A vapor chamber, also known as a planar heat pipe or micro heat pipe, is a device used for efficient heat transfer. It uses the phase change process of the working fluid to transfer heat in a closed cavity. When heat is input through the hot end of the vapor chamber, the working fluid in the cavity begins to absorb heat and evaporates into steam. This phase change process converts heat into steam energy, thereby achieving heat transfer. The generated steam flows to the cold end of the vapor chamber under the action of the pressure difference, and the steam flows to the cold end through structures such as heat conduction paths or pipes. At the cold end of the vapor chamber, the steam releases heat and re-condenses into liquid. In this process, heat is transferred to the surrounding environment or other heat sources. The condensed liquid returns to the evaporation zone through a capillary structure (such as a capillary tube or porous material) and is heated again, forming a cycle.

[0003] The design of the vapor chamber allows heat to be transferred inside the working fluid through phase change, avoiding the thermal resistance and thermal interface problems in traditional heat transfer. Compared with traditional heat conduction methods, the vapor chamber can achieve higher heat transfer efficiency and uniformity. At the same time, the vapor chamber has a small size and weight, and is suitable for various occasions with limited space or strict heat dissipation requirements.

[0004] In view of the above-mentioned related technologies, the inventor believes that the area on the outer wall of the ship's cabin that needs to be heat-conducted is large, while the traditional heat spreader is used for heat dissipation of electronic components, and the area is small, which is not suitable for large areas outside the cabin. Splicing will increase the complexity of the system and reduce reliability; scaling up the traditional heat spreader will be limited by the overall structural strength. Summary of the invention
