Stainless steel heat exchange tubes are widely used in daily life. It is a component in the heat exchanger. It is placed in the cylinder and is often used for heat exchange between the two media. What are the three types of heat transfer?
Then let’s take everyone to understand the three heat exchange forms of stainless steel heat exchange tubes.
1. Conduction
Conduction is the transfer of heat between particles with lower energy and particles with higher energy through direct contact and collision. This method is mainly used for the heat transfer between the air conditioner refrigerant and the cooling fins.
2. Convection
Convection means that the hotter part and the colder part of the gas or liquid make the temperature uniform by circulating and rotating, so that the temperature of the two parts can be kept in balance. The fan in the air conditioner condenser drives the flow of gas, which also belongs to “forced convection” heat dissipation Way.
3. Radiation
Radiation is to radiate heat energy from the heat source directly to the outside world. This process is related to the surface color, material and temperature of the heat source. The speed of radiation is relatively slow, so the role played by the radiator in heat dissipation is relatively limited (radiation energy is carried out in a vacuum).
The above three heat exchange forms of stainless steel heat exchange tubes, in the daily heat transfer process, these three methods are not independent, but occur simultaneously and work together.
