The working principle of the invention is as follows: the phenomenon in which energy that occurs without applying work migrates from a high-temperature object to a low-temperature object, or heat migrates from a high-temperature portion to a low-temperature portion in one object is called heat transfer. The change in energy within the object is measured by heat in the heat transfer. Heat transfer takes three forms, heat conduction, heat radiation and heat convection. In practice, these three heat transfer modes often coexist at the same time, thus increasing the complexity of the process. The invention relates to a blackbody heat source device, which mainly relates to two modes of heat conduction and heat radiation. Heat conduction is a macroscopic phenomenon in which heat is transferred from high temperature to low temperature due to thermal movement of molecules or atoms constituting the system and their interactions. The manner in which energy is transferred by means of electromagnetic waves is called thermal radiation. It has a continuous spectrum of radiation with wavelengths extending from the far infrared region to the ultraviolet region, but primarily by the longer wavelength infrared. The invention mainly adopts air isolation to weaken heat conduction, namely, under the basic supporting effect of the heating element, the heating element is prevented from contacting with the base as much as possible to form air isolation; and secondly, the heat insulation plate is arranged to reduce the influence of heat radiation on the control area, and the partition plate is arranged on the propagation path of the radiation electromagnetic wave of the heating body, namely, the partition plate is arranged between the control area and the heating area, so that the heat radiation is prevented from directly contacting the control area, the heat radiation on the control area is effectively reduced, and the long-term normal operation is ensured.

The beneficial effects of the invention are as follows: according to the small blackbody heat source provided by the invention, the partition plate is arranged between the heating area and the control area, so that the heat radiation of the heating area to the control area is effectively weakened, meanwhile, the air isolation layer is formed between the inner wall of the shell and the peripheral side wall of the base, and only the point contact is formed between the heating element and the base through the arrangement of the protrusions, so that the heat transfer of the heating area to the control area and the shell is effectively controlled and weakened, the volume of the heating device is reduced, and the service life is prolonged. In general, the heating device has the advantages of small volume, simple structure, convenient carrying, installation and use and strong practicability, and is prepared to be popularized in the industry.
