Product Description

 

Overview
It is mainly used to test the thermal resistance of thin thermal conductors, solid electrical insulation materials, thermal conductive silicone grease, resin, 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 in the form of solid sheets, and a frame can be used to detect powdery materials and paste materials.

Instrument reference standards

• ASTM D5470-2017 "Test Standard for Heat Transfer Performance of Thin Thermal Conductive Solid Electrical Insulating Materials"
• MIL-I-49456A "Insulating Sheet, Thermal Conductive Resin, Thermal Conductive Glass Fiber Reinforcement";
• "Method for Determination of Thermal Conductivity of Beryllium Oxide Porcelain";
• "Electrical Insulating Materials" Thermal Conductivity Performance Test Method";

Features

• The instruments are all designed and manufactured in accordance with ASTM D5470-2017 standards.
• Xiangyi Instrument has accumulated more than ten years of experience in manufacturing and user practice for this product, which has enabled the product's performance to be continuously improved and matured.
• It adopts servo motor to control precise automatic pressurization and automatic thickness measurement device, and is connected to a computer to achieve fully automatic control.
• The instrument uses 6-point temperature gradient detection to improve test accuracy. A protective thermal device (thermal protection of the sample) is added around the test rod in the test head to reduce the impact of ambient temperature on the test.
• It can detect thermal resistance curves under different pressures, adopt optimized mathematical models, and measure multiple parameters such as material thermal conductivity and thermal resistance, as well as contact thermal resistance at the interface.
• The latest technology is used to automatically compensate the cold end temperature, eliminating the need to add ice water compensation device.
• It is widely used in material thermal conductivity analysis and testing in colleges and universities, scientific research units, quality inspection departments and production plants.
