Technical Field

Background
Radiation heat transfer: blackbody radiation has two manifestations, surface radiation and cavity radiation, which are essentially the same. The laws describing black body radiation are mainly planck's law, wien's displacement law and stefan boltzmann's one law. The full-wavelength radiation power of the black body surface is as follows: eb=σT4
This is the Stefan-Boltzmann law; the cavity with its inner surface at a uniform temperature has properties closest to a black body. If a small hole is formed in the cavity, it can be proved that the radiation leaving the small hole depends only on the surface temperature according to the thermodynamic principle and is equivalent to the radiation energy of the blackbody surface emission in the blackbody cavity, wherein the radiation energy per unit volume of the blackbody radiation field exists is called radiation energy density.
According to the theory of black body radiation, the temperature of the existing baking room is 10-60 ℃ higher than the ambient temperature, so the heat leakage amount can be calculated through radiation heat transfer calculation, and the heat leakage amount is larger than the heat leakage amount calculated through heat conduction of the heat insulation material by an order of magnitude, so for the baking room, the radiation heat leakage is more than the heat leakage amount calculated through heat conduction of the heat insulation material, and particularly when the ambient temperature is low at night, the radiation heat leakage is a main contributor of the heat leakage of the baking room, the existing various baking rooms are calculated through heat conduction heat leakage, the heat insulation material with lower heat conduction coefficient is replaced, the leakage is reduced, and the heat leakage of the baking room through heat radiation is larger than the heat.
