What are the factors affecting the performance of vapor chambers?
Best insight from top research papers
The performance of vapor chambers is affected by several factors. One important factor is the width of the gas channels inside the wick construct, which influences the maximum temperature difference and thermal resistance of the soaking plate . Another factor is the type of wick used in the vapor chamber. Different types of wicks, such as micro-channel, sintered powder, and sintered screen, have their own benefits and drawbacks . The presence or absence of wettability patterns on the condenser surface also plays a significant role in the performance of vapor chambers. Wettability patterns can improve the condensation process and liquid mobility, leading to a reduction in thermal spreading resistance and an overall improvement in heat transfer coefficient . Additionally, the selection of fluid, filling rate of liquid, size and distribution position of heat source input power, and working angle are factors that can affect the performance of the uniform temperature plate in vapor chambers .
