Problems solved by technology

The plate heat pipe measurement device absorbs the dimensional error caused by the processing of the plate heat pipe through the elastic deformation of the thin wall. The large interface thermal resistance makes the heat transfer efficiency of the heat pipe measurement lower than its actual heat transfer efficiency, thus affecting the accuracy and reliability of the plate heat pipe measurement device

Abstract

The present invention provides a heat tube measuring unit. It contains heating arrangement with one heat block; one cooling unit with one inserting port; one end part for inserting measured heat tube; wherein said heat block having one trough connected with another end of measured heat tube, said trough inner wall surface set with one heat interface material. Said heat interface material can fill miniature interstice between trough and heat tube contact interface when becomes soften by heating, thereby capable of reducing thermal resistance between heat block trough and heat tube, to make heat tube measuring unit having high metering accuracy and reliability, suitable for different kinds shape of heat tube metering.

Description

【Technical field】 [0001] The invention relates to the field of heat conduction, in particular to a heat pipe measuring device. 【Background technique】 [0002] In recent years, with the rapid development of electronic technology, the high frequency and high speed of electronic devices and the density and miniaturization of integrated circuits have caused a sharp increase in the heat generated by electronic devices per unit area. The heat pipe technology, with its high efficiency, compactness, flexibility and reliability, is suitable for solving the heat dissipation problems of current electronic devices due to performance improvement, and has gradually become the mainstream heat dissipation method of current electronic devices. [0003] The heat pipe is usually a hollow sealed tube body, including a shell, a capillary wick close to the inner wall of the shell, and a working fluid sealed in the shell. One end is the evaporation end (heating end), and the other end is the conde...
