Thermal irradiation: the objects will launch energy by its own temperature. No matter what about the weather and the surrounding, objects often give in the form of electromagnetic irradiation energy. The higher the temperature the more intense irradiation, and irradiation of the wavelength distribution also changes with temperature; if the temperature is low, mainly invisible infrared irradiation, and even higher at 500 ℃ when the visible light is gradually even stronger UV emission irradiation. Thermal irradiation is one form of heat transfer; and heat conduction, convection different, it can heat through the vacuum speed of light to pass from one object to another object. The energy through space which comes from sun to earth is in the irradiation way.

Irradiation: micro-wave (mechanical waves or wave) or a large number of micro-particle emitters start from their selves, spread in the space or medium in the process in all directions. Can also mean a large number of micro-wave energy or particle itself.

Irradiation heating: a method which take irradiation heating as mainly transfer heating way. the cooling equipment can be separated into low temperature （ below 80 ℃）、medium temperature （ 80-200 ℃） and high temperature（ 500-900 ℃）, according to the temperature of the heat bringer.

Irradiation heat transfer: a process what is transferred heat through irradiation heating between the goods which will not keep in touch. This transfer process is not unilateral but a mutual exchange of objects, but the result is always the heat is transferred from the high temperature object to the low.

Heat exchange: also named” heat conducting”. Transferring heat is the most basic way. This is due to a large number of molecules, atoms or electrons hit each another, so it is a process that energy be transferred from the upper part of the object to the lower part. It is the main mode of heat transfer in solid. In gas or liquid, and heat transfer process will happen simultaneously with convection.

Convection: it is a process that the hot part of liquid or gas and the cold part through the circular flow between each other and mixed, to make the temperature tends to be uniform. It is a main heat transfer mode of liquid or gas , often happen naturally (natural convection), such as water will has up and down circulation when boil the water, the atmosphere generated circulation by the lower heat flows up and down cycle. The reason caused natural convection is uneven temperature pressure or density difference.
