DRL-III Solid Thermal Conductivity Machine

1. Overview

This instrument mainly tests the thermal resistance of thin thermal conductor, solid electrical insulation material, thermal resin, thin thermal conductor, solid electrical insulation material, thermal resin, silica gel, silicone grease, Plastikowy, guma, farba, aluminum substrate, materiały polimerowe, ceramika, beryllium oxide porcelain, alumina porcelain and other fine materials, as well as the contact thermal resistance at the solid interface and the thermal conductivity of the material. The detection material is solid flake, and the enclosing frame can detect powder material and paste material.

Instrument reference standard:

MIL-I-49456A (insulation sheet, thermal resin, thermal guide glass fiber reinforced); GB 5598-2015 (Beryllium oxide porcelain thermal conductivity determination method rod shaft method); ASTM D5470-12 (Test standard for Heat Transfer Properties of Thin thermal conductive solid electrical insulating materials), GB/T38712-2020 (Experimental method for Thermal conductivity of ultra-thin glass heat flow method), GB/ T29313-2012 Test method for heat transfer properties of electrical insulating materials, itp.

Funkcje instrumentu:

automatic pressure, automatic thickness measurement, experiment automatic control. 6 point temperature gradient detection, improve the test accuracy. The thermal resistance curve can be detected under different pressures, and the thermal conductivity and thermal resistance of the material and the contact thermal resistance at the interface can be measured by using an optimized mathematical model.

Widely used in colleges and universities, scientific research units, quality inspection departments and production plant material analysis and testing.
