Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for blackbody radiation sources, specifically to a heating and cooling device and method for an ultra-high temperature blackbody radiation source. Background Technology

[0002] Ultra-high temperature blackbody cavity radiation sources are mainly used for calibrating and verifying the temperature scales of various infrared measuring devices, such as infrared thermometers, thermal imaging systems, heat flow meters, and spectral analysis systems. Specifically, a blackbody calibration source (also known as a blackbody radiation source) is a device that simulates the characteristics of a blackbody. It can generate stable infrared radiation at a known temperature, which is used to calibrate and verify the temperature scales of various infrared measuring devices.

[0003] In the prior art, patent document CN221006581U discloses an ultra-high temperature blackbody radiation source. This technical solution relates to the field of blackbody radiation technology, and in particular to an ultra-high temperature blackbody radiation source, comprising: a vacuum Dewar flask with a temperature measuring channel and a radiation channel formed at its two ends, and high-temperature resistant glass sealed at the ports of the radiation channel and the temperature measuring channel; an ultra-high temperature radiation cavity installed inside the vacuum Dewar flask, with a temperature measuring port and a radiation port formed at its two ends; a plasma heater installed on the body of the vacuum Dewar flask and corresponding to the position of the ultra-high temperature radiation cavity; a vacuum valve installed on the vacuum Dewar flask; a water-cooled flange installed on the vacuum Dewar flask; and a photoelectric pyrometer located on one side of the temperature measuring channel. The photoelectric pyrometer, the temperature measuring channel, the temperature measuring port, the radiation channel, and the radiation port are coaxially arranged. This utility model can improve the temperature resistance of the ultra-high temperature radiation cavity, thereby increasing the radiation temperature of the blackbody radiation source to meet the requirements of infrared radiation calibration.

[0004] However, the above-mentioned technical solutions suffer from uneven heating and poor heat conduction, resulting in localized excessively high or insufficient temperatures in the radiation source, affecting the accuracy of radiation output. Furthermore, the cooling efficiency is low, the cooling structure design is unreasonable, the cooling medium circulation is not smooth, and heat cannot be dissipated quickly, which can easily lead to overheating and damage to equipment components, shortening the equipment's service life. Moreover, the coordination between heating and cooling is poor, with the heating and cooling modules operating independently and poorly connected. During the switching process, the temperature fluctuates greatly, affecting the operational stability of the radiation source.
