Description

Technical Field

[0001] This invention relates to the field of blackbody radiation source technology, specifically to a high-efficiency, continuously powered, ultra-high temperature blackbody cavity radiation source. Background Technology

[0002] Ultra-high temperature blackbody cavity radiation sources are mainly used to calibrate and test the temperature scales of various infrared measurement 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 and is used to calibrate and test the temperature scales of various infrared measurement devices.

[0003] In the prior art, patent document CN221006581U discloses an ultra-high temperature blackbody radiation source, which relates to the field of blackbody radiation technology, and in particular 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, with the photoelectric pyrometer, temperature measuring channel, temperature measuring port, radiation channel, and radiation port 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 discontinuous power supply, making it impossible to achieve long-term continuous power supply under ultra-high temperature environments. This results in unstable radiation output, affecting testing and calibration accuracy. Furthermore, the temperature stability is poor, and heat easily accumulates under ultra-high temperature operating conditions. The lack of an efficient continuous cooling structure leads to large temperature fluctuations in the radiation source, making it impossible to maintain a constant ultra-high temperature environment. Moreover, the heat dissipation efficiency is low, the cooling structure design is unreasonable, and heat conduction is not smooth, which can easily lead to overheating and damage of components, shortening the service life of the equipment. Based on this, the present invention provides an efficient and continuously powered ultra-high temperature blackbody cavity radiation source to solve the problems mentioned in the background art.

The inner walls of the multiple mounting brackets are each equipped with an external conductive plate. The multiple external conductive plates are grouped in pairs, and a graphene heat-conducting plate is fixedly connected between each group of external conductive plates.

[0009] The beneficial effects of adopting the above-mentioned further solution are as follows: the radiation source structure is set on the inner wall of the outer enclosure, generating ultra-high temperature blackbody radiation, which is output through a radiation tube. The inner partition is fixed to the inner wall of the outer enclosure, separating the internal space of the outer enclosure, providing an installation carrier for other components of the radiation source structure, and also serving as heat insulation to prevent the heat generated by the radiation source from being transferred to other areas of the outer enclosure. The internal mounting bracket is fixedly connected to one side of the top of the inner partition, fixing the radiation tube and ensuring that the radiation tube is installed firmly and positioned accurately. The radiation tube is installed on the inner wall of the internal mounting bracket, transmitting the radiation energy generated by the radiation source, and outputting it accurately through the radiation hole, reducing radiation energy loss.

A rear sealing plate 19 is installed on the rear end of the outer casing 1. Side sealing plates 110 are installed on both sides of the outer casing 1.

[0058] The control panel 11 is installed on the front side of the external enclosure 1 to realize the overall control and parameter monitoring of the equipment. The temperature controller 12 is electrically connected to one side of the front side of the control panel 11 to adjust and control the working temperature of the radiation source and ensure that the temperature is stable within the set range. The start switch 13, the gas source conversion switch 14, and the flow meter 15 are sequentially electrically connected to the front side of the control panel 11.

The main power switch 17 is electrically connected to the front side of the control panel 11 to control the power supply of the entire equipment and ensure operational safety.

[0059] The working principle of this invention is as follows: The operator turns on the main power switch 17, starting the power supply 39. The power supply 39 supplies power to the external magnetic induction coil 32, which generates an alternating magnetic field, inducing a current in the graphite cavity 31, thus achieving electromagnetic induction power supply. Simultaneously, the argon gas pipe 310 is activated through the gas source conversion switch 14, introducing argon gas into the graphite cavity 31 to form an inert gas protective atmosphere and prevent oxidation of the graphite cavity 31. The target ultra-high temperature is set through the temperature controller 12, and the radiation source 24 is activated, allowing the equipment to enter its optimal operating state. During the preheating phase, the continuous cooling structure 4 is activated simultaneously. The cooling medium circulates between the cooling pipe 44, the vertical transmission pipe 45, the guide box 412, and the top water storage tank 413, initiating heat dissipation. Under the action of the external magnetic coil 32, the graphite cavity 31 continuously generates an induced current, converting electrical energy into heat energy, providing continuous and stable energy support for the radiation source 24. Under the energy supply, the radiation source 24 generates ultra-high temperature blackbody radiation. The radiation energy is transmitted through the radiation tube 22 and precisely output through the radiation hole 16 for testing. Calibration and other tasks are performed. The temperature controller 12 monitors the radiation source temperature in real time and automatically adjusts the power supply of the external magnetic coil 32 to ensure that the radiation source temperature is stable within the set range, thus ensuring the stability and consistency of the radiation output. During equipment operation, components such as the graphite cavity 31, radiation source 24, and radiation tube 22 generate a large amount of heat. The external conductive plate 42 quickly absorbs the heat from the graphite cavity 31 and transfers it to the graphene heat-conducting plate 43. The graphene heat-conducting plate 43 efficiently conducts the heat to the cooling pipe 44. The cooling pipe 44 contains... After absorbing heat, the cooling medium flows into the guide box 412 through the vertical transmission pipe 45, the outlet pipe 47, and the guide pipe 411. After being cooled by the top water storage tank 413, it flows back to the cooling pipe 44 through the inlet pipe 46, forming a continuous circulating heat dissipation loop. At the same time, the through-tube radiator 23 dissipates the heat radiating through-tube 22, and the cooling bend 49 further absorbs the heat of the through-tube radiator 23. It is connected to the circulating heat dissipation loop through the transmission pipe 410 to achieve synergistic heat dissipation, ensuring that the temperature of each component of the equipment is stable within a safe range and avoiding overheating damage.
