The heat transfer principle of stainless steel heat exchange tubes can be understood metaphorically as two people shaking hands to transfer body temperature. However, the heat exchange tubes transfer heat, and the hands are equivalent to stainless steel tubes. The process of shaking hands occurs between two fluids (cold water and hot water).

Introduce in simple and popular language as follows:

1. Hot fluid “sticking” stainless steel pipe

Suppose you have a stainless steel tube with a high-temperature fluid flowing inside (such as hot water or steam from a factory) and a low-temperature fluid flowing outside (such as cold water). When high-temperature fluid flows through the pipe, the heat will “stick” to the inner wall of the stainless steel pipe, just like the wall of a hot water cup will become hot.

2. Stainless steel pipes “transport” heat

The metallic properties of stainless steel make it like a “delivery channel”: the heat absorbed by the inner wall will quickly pass through the pipe wall and be transferred to the outer wall. This process is similar to stirring soup with a metal spoon, and the handle quickly heats up – metals are naturally good at conducting heat.

3. Cold fluid “steals” heat

The heat on the outer wall will be “taken away” by the low-temperature fluid (such as cold water) outside the pipe. When cold water flows, it constantly takes away heat, just like wind blowing through a hot phone radiator, the more it flows, the faster it dissipates heat.

The principle is similar to that of a car radiator, where hot water from the engine flows through metal pipes and cold air blows outside the pipes, taking away the heat.
