There are three types of heat transfer in stainless steel heat exchange tubes: radiation, convection, and conduction.
Among them, conduction is a form of energy transfer through contact and impact of low-energy particles and high-energy particles. This form of heat transfer is mainly used for heat transfer between air-conditioning refrigerants and heat sinks, and is also a common form of heat transfer.
Convection is a process in which hotter and cooler parts of a gas or liquid are circulated to achieve uniformity, as is the case with fan-driven gas flow in air conditioner condensers.
The last type of radiation refers to the process of directly transmitting heat energy to the heat source and the surface color of the heat source. The process is related to the temperature of the material. The radiation speed is very slow, and the heat dissipation effect in the radiator is very limited. (can be done in vacuum)
The above three forms occur simultaneously and work together in the daily heat transfer!
