TPS Transient Plane Source Thermal Conductivity Analyzer for Metal Ceramic Composite Materials

Transient Plane Heat Source Method Thermal Conductivity Meter

Instrument Introduction

BXT-DR-S is a thermal conductivity tester developed using transient planar heat source technology (TPS), which can be used to test the thermal conductivity performance of various types of materials. The transient planar heat source method is the latest type of m
ethod for studying thermal conductivity performance, which has taken measurement techniques to a whole new level. The ability to quickly and accurately measure thermal conductivity when studying materials provides great convenience for enterprise quality monitoring, material production, and laboratory research. The instrument is easy to operate, the method is simple and easy to understand, and it will not cause damage to the tested sample.

Working principle

Transient planar heat source technology (TPS) is a novel method for measuring thermal conductivity. The principle of determining the thermal properties of materials is based on the transient temperature response generated by a disc-shaped heat source with step heating in an infinite medium. Using thermal resistant materials to create a flat probe that serves as both a heat source and a temperature sensor. The thermal resistance coefficient of an alloy is linearly related to temperature and resistance, which means that by understanding the change in resistance, the heat loss can be determined, thereby reflecting the thermal conductivity of the s
ample. The probe of this method is a continuous double helix structure thin film formed by etching conductive alloy, with a double-layer insulating protective layer on the outer layer and a very thin thickness, which gives the probe a certain mechanical strength and maintains electrical insulation with the sample. During the testing process, the probe is placed in the middle of the sample for testing. When current passes through the probe, a certain temperature rise is generated, and the heat generated simultaneously diffuses to the samples on both sides of the probe. The speed of thermal diffusion depends on the thermal conductivity characteristics of the material. By recording the temperature and the response time of the probe, the thermal conductivity can be directly obtained from a mathematical model.

Test object

Metals, ceramics, alloys, ores, polymers, composites, paper, fabrics, foamed plastics (thermal insulation materials and plates with flat surfaces), mineral wool, cement w
alls, glass reinforced composite plates CRC, cement polystyrene plates, sandwich concrete, glass reinforced steel panel composite plates, paper honeycomb plates, colloids, liquids, powders, granular and paste solids, etc., have a wide range of test objects.
