The invention provides a heating unit of a thermal conductivity tester, the heating unit of the thermal conductivity tester includes: a first protrusion, the first protrusion is arranged on a metering plate and / or a protective plate, so that the metering plate and the protective plate A first gap is formed between the plates, and the width of the first gap increases from the direction away from the heating element to the direction close to the heating element. In the heating unit of the thermal conductivity measuring instrument provided by the present invention, the width of the first gap increases from the direction away from the heating element to the direction close to the heating element, and the increased width can reduce the heat transfer from the metering plate to the protective plate. It can also meet the strength of the metering plate, and the ratio of the gap area can also meet the requirements.
Description
technical field [0001] The invention relates to the technical field of measurement, in particular to a heating unit of a thermal conductivity measuring instrument. Background technique [0002] The thermal conductivity tester is used to measure the thermal resistance and thermal conductivity of thermal insulation materials. Thermal conductivity is an important parameter used to measure the thermal conductivity and thermal insulation performance of heat-resistant materials. The accuracy of thermal conductivity measurement results is closely related to the heating unit of the measuring instrument. [0003] In the prior art, the heating unit of the thermal conductivity measuring instrument includes a metering plate and a protective plate. The protective plate is arranged on the outside of the metering plate along the circumference of the metering plate. The protective plate is used to prevent the heat loss of the metering plate. The metering plate and the protective plate Ther...
