DRL-III thermal conductivity tester (heat flow method), thermal resistance tester

Detailed introduction

DRL-III thermal conductivity tester (heat flow method), thermal resistance tester

I. Introduction:
It is mainly used to test the thermal resistance of thin thermal conductors, solid electrical insulation materials, thermally conductive silicone grease, resins, rubber, beryllium oxide porcelain, alumina porcelain and other materials, as well as the contact thermal resistance at the solid interface and the thermal conductivity of the material. The detection material is a solid sheet, and the enclosing frame can detect powder state materials and paste materials.
Instrument reference standards: MIL-I-49456A (insulation sheet, thermally conductive resin, thermally conductive glass fiber reinforced); GB 5598 (method for measuring the thermal conductivity of beryllia porcelain); ASTM D5470-2012 (thin thermally conductive solid electrical insulation Test standards for heat transfer performance) and so on.
Features of thermal conductivity tester: The servo motor is used to control the precise and automatic pressurization, the automatic thickness measurement device, and the computer to achieve full automatic control. The instrument uses 6-point temperature gradient detection, which improves the test accuracy. It can detect thermal resistance curves under different pressures, and adopts optimized mathematical models to measure multiple parameters such as thermal conductivity and thermal resistance of materials and contact thermal resistance at the interface.
Widely used in colleges and universities, scientific research units, quality inspection departments and production plants for thermal analysis analysis of materials.
