| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 88 === The purpose of this thesis is to manufacture a micro heat pipe that uses copper powder as wick structure to provide a passive heat transfer design for notebook computers. Consider three effects of powder size, sinter time and sinter temperature, both the porosity and permeability can be measured. We also observe the variety of permeability and conductivity at different porosity.
Also this thesis provides a method of manufacturing sinter heat pipe that uses copper powder sintered as wick structure in the laboratory and doing the performance testing on the heat pipe. We found that the operation angle does not have significant influence on the thermal resistance of the heat pipe, which means the capillary force of the wick structure is enough large than the gravitational force, so the thermal resistance not effected by the gravity.
