When measuring the heat dissipation rate of copper plate, why should the sample be covered on it?
In this experiment, the area involved in the heat dissipation is only the lower surface and the side. The upper surface is the part responsible for heat conduction, and a part of the heat is absorbed by the object to be measured, and this part of the heat is neglected.
Heat dissipation rate is the rate at which heat releases heat in the air.Cooling mode can be divided into air cooling and liquid cooling, heat pipe cooling, semiconductor refrigeration, refrigeration and other chemical. The rate of heat dissipation in different ways is different; in the same way, the temperature is different when the material is different or the environment is different.
