Abstract

The invention relates to a radiation heating and temperature measuring device in the phase transition process of a low-melting translucent material, belonging to the technical field of materials. The requirement of the device for the experiment of the phase transition process of the low-melting-point translucent material under irradiation conditions is met, and the requirement of simultaneously measuring the temperature distribution of the translucent material in the phase transition process during the phase transition process is satisfied. In the present invention, the infrared thermal radiation emitted by the halogen black lamp in the infrared light box is reflected by the parabolic reflector and then vertically irradiated onto the sample in the sample tank from right above. A plurality of thermocouples are arranged in the vertical direction in the sample tank. The bottom of the sample tank and the vertical side wall are provided with an insulating layer. The outer edge of the sample tank is provided with an observation slit. The movement of the phase transition interface of the sample is observed through the observation slit. . The temperature distribution in the sample layer is monitored by a thermocouple, and the thermocouple signal is recorded by a paperless recorder, which meets the needs of observing the phase transition process of the sample and recording the temperature change during the phase transition process of the sample. It is suitable for observing the phase transition process and recording temperature changes at the same time.

Description

technical field [0001] The invention belongs to the technical field of materials, and relates to a radiation heating and temperature measuring device used in the phase transition process of low-melting translucent materials. Background technique [0002] The phase transition process of low-melting translucent materials under the action of thermal radiation is very important for many technical and scientific problems, especially the radiation-induced melting process is currently of great interest. For example, the prediction of the natural melting rate of the ice layer, the development of phase change energy-saving wall materials, radiation deicing, stealth of phase change materials, etc., these heat transfer problems are closely related to the melting process of materials under the action of radiation. The temperature distribution during the phase transition has an important impact on the forming and application of materials. The uneven temperature will lead to stress in the...
