Introduction
There are three basic forms of heat transfer: heat conduction, heat radiation and heat convection. This vacuum extraction equipment heats the air and circulates it in the inner cylinder, heating the inner cylinder and increasing the gas decomposition speed.
Vacuuming is to extract the medium in the cylinder shell and the inner cylinder, so as to achieve the purpose of reducing heat convection. The effect of heat preservation is affected by the vacuum degree. The better the vacuum effect, the better the heat preservation effect.
