There are three heat transfer methods of stainless steel heat exchange tubes, namely conduction, convection and radiation.
First of all, let’s talk about the stainless steel heat exchange tube. The stainless steel heat exchange tube is one of the components used in the heat exchanger. It is placed inside the cylinder and used for heat exchange between two media.
So how does the heat transfer of stainless steel heat exchange tubes, that is, what we commonly call heat dissipation, work?
1. Convection
Convection is the circulation of hotter and cooler parts of a gas or liquid to equalize the temperature. For example, the fan in the air conditioner condenser drives the gas flow, which also belongs to forced convection heat dissipation.
2. Conduction
Conduction refers to the transfer of energy by direct contact and collision between lower energy particles and higher energy particles. The heat transfer between the air-conditioning refrigerant and the cooling fins is mainly by conduction, which is also a common way of cooling.
3. Radiation
Radiation refers to the direct dissipation of thermal energy from a heat source to the outside world. This process is related to the color, material and temperature of the surface of the heat source, and the radiation speed is slow, so it plays a limited role in the radiator (radiation can be carried out in a vacuum).
The above three heat transfer methods are not carried out alone in daily heat transfer, but occur simultaneously and work together.
