    Basic principles of heat transfer

    a, heat flows from the high temperature zone to the low temperature zone; b, the heat emitted from the high temperature zone must be equal to the heat absorbed from the low temperature zone. The process of heat transfer can be distinguished into two categories: a, where the temperature at various points in the object does not change with time, the heat transfer process is called stable heat transfer process; b, the opposite is called unstable process.
