Abstract

The invention discloses a heat-pipe performance comprehensive measurement device and method. One end of the heat-pipe(5) to be measured is mounted on a heating device(3), another end of the heat-pipe is mounted on a cooling device (7); two rotary sliding devices (2) capable of rotating and linearly sliding on the plane surface of a work platform (1) are mounted on the work platform (1), and the work platform (1) is mounted on the bracket (10) capable of rotating on the vertical plane; a temperature measurement instrument is respectively connected with the heating device (3) and the cooling device (7). The two ends of the heat-pipe are clipped on the heating device and the cooling device and the heating and cooling power is adjusted and the starting time, isothermal performance, maximum heat-transmission power and heat resistance of the heat-pipe is measured by the temperature measurement instrument; and the performance of the heat-pipe to be measured of various bending angle and length is measured by adjusting the rotary sliding device; and the performance of the heat-pipe to be measured at different inclination angle is measured by adjusting the work platform.

Description

technical field [0001] The invention relates to heat transfer performance detection of heat pipes, in particular to a comprehensive measurement device and method capable of accurately and quickly measuring the start-up time, maximum heat transfer power and isothermal performance of heat pipes with different lengths, bending angles and inclination angles. Background technique [0002] As a high-efficiency heat transfer element, the heat pipe has been more and more influential in the field of heat transfer technology since its appearance in the 1960s due to its high efficiency, compactness, dexterity and reliability. It is used in the temperature control of spacecraft, electrical appliances and It is widely used in the cooling of electronic equipment and devices, isothermal furnace, standard black body, solar energy utilization and industrial waste heat recovery. [0003] In order to ensure the reliability of the heat pipe during operation and give full play to its heat transf...
