Abstract

The application discloses a heat transfer coefficient test apparatus and a heat transfer coefficient measuring method. The heat transfer coefficient test apparatus comprises: a protective component including a first portion in U shape and a second portion inside the first portion; a heating component arranged at the bottom of the first portion, wherein the second portion divides a receiving spaceformed by the first portion into two receiving spaces to receive a comparison reference component and a component under test; the comparison reference component and the component under test which respectively include a heating plate, a standard test piece, a piece under test and a heat-dissipating plate which are arranged in stacked manner; temperature measuring components arranged on the upper and lower surfaces of the standard piece and the piece under test in order to monitor changes in the surface temperatures of the standard piece and the piece under test. The apparatus and method disclosed herein help solve the technical problems that measurement of heat transfer coefficient in the prior art is highly difficult and equipment of the prior art is highly complex.

Description

technical field [0001] The present application relates to the field of measurement technology, in particular to a thermal conductivity testing device and a method for measuring thermal conductivity. Background technique [0002] With the development of high integration and miniaturization of electronic equipment, the problem of heat dissipation is particularly important. In thermal design, it is often necessary to consider the heat conduction between power devices and heat sinks, and insulating and heat-conducting materials have become their preferred transfer medium, which provides powerful heat dissipation measures for the high integration of electronic equipment, as well as ultra-small and ultra-thin. More and more products begin to use insulating and heat-conducting materials to improve heat dissipation efficiency and meet reliability requirements. Therefore, in thermal design, it is an essential requirement to obtain the steady-state thermal performance parameters of i...
