Embodiment Construction

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0021] Such as figure 1 , figure 2 As shown, a thermal conductivity tester of the present invention includes a frame, a heating module, a cooling module and a measuring module. The heating module is installed in the upper middle part of the rack, and the cooling module is installed in the lower middle part of the rack. The bottom surface of the heating module and the top surface of the cooling module form the upper and lower pressing surfaces of the sample 11 to be tested. The loading module is installed on the top of the rack and applies loading and pressure to the top surface of the heating module.

[0022] The measurement module includes thermocouples embedded in the heating module and the cooling module. Drill a...

Abstract

The present invention relates to a thermal conductivity tester, comprising a frame, a heating module, a cooling module and a measuring module, wherein the heating module is installed in the upper middle of the frame, and the cooling module is installed at the lower part of the frame In the middle, the loading module is installed on the top of the rack and loads and presses the top surface of the heating module. The measurement module includes a thermocouple embedded in the heating module and the cooling module. The heating module A heat insulating device (21) is installed on the outer casing of the module and the cooling module, and the heat insulating device (21) is locked and fixed by a fastening device (10), and the fastening device (10) includes two clamps, One side of the two clamps is connected by a hinge, and the other side is detachably connected. The thermal conductivity tester of the invention has the advantages of simple structure, convenient installation and easy maintenance.

Description

technical field [0001] The invention relates to the technical field of thermal physical property testing of materials, in particular to a thermal conductivity tester. Background technique [0002] With the extension of LEDs to emerging fields such as rear projection, street lights, and automotive lights, LED devices as light sources are also developing towards high power density, high brightness, and high integration. There are many problems such as luminosity reduction, wavelength shift, and shortened service life. Therefore, the heat dissipation of LEDs is particularly prominent. At present, heat dissipation has become one of the technical bottlenecks restricting these applications. [0003] LED substrate, chip bonding layer, and thermal interface thermal grease, as part or intermediate links of the heat dissipation path, play a connecting role in the heat dissipation of the entire system. Once the materials are not selected properly, it will cause heat dissipation proble...
