传热是指由于温度差引起的能量转移，又称热传递。由热力学第二定律可知，凡

It refers to the energy transfer due to a temperature difference caused by the transfer, also known as heat transfer. Seen from the second law of thermodynamics, when the temperature difference where there exist, heat transfer from the high temperature is bound to low temperature, and thus the nature of heat transfer is a very common engineering art a transfer phenomena. Whether in the energy, aerospace, chemicals, power, metallurgy, machinery, construction and other industrial sectors, or in other sectors such as agriculture and environmental protection are involved in many issues related to heat transfer.

Heat transfer refers to the transfer of energy due to temperature difference, also known as heat transfer. It can be seen by the second law of thermodynamics that when there is a temperature difference, heat is bound to pass from high temperature to low temperature, so heat transfer is a very common transmission phenomenon in nature and engineering technology. Whether in the energy, aerospace, chemical, power, metallurgy, machinery, construction and other industrial sectors, or agriculture, environmental protection and other sectors are involved in many issues related to heat transfer.

Heat transfer refers to the energy transfer caused by temperature difference, also known as heat transfer. According to the second law of thermodynamics, when there is a temperature difference, heat must be transferred from high temperature to low temperature, so heat transfer is a very common phenomenon in nature and engineering technology. No matter in energy, aerospace, chemical industry, power, metallurgy, machinery, construction and other industrial sectors, or in agriculture, environmental protection and other sectors, there are many issues related to heat transfer.<br>
