Heat exchanger in Bordeaux, Gironde: how does the heat exchanger work?

The role of the heat exchanger is to transfer heat energy from one fluid to another without the two fluids mixing. Heat exchangers are found, for example, in heating systems. In this case, a first fluid, called the “heater”, heats the secondary fluid. It is important that the two liquids are at different temperatures, either hot or cold.


In order to transfer the heat correctly, the heat exchanger needs a sufficiently conductive material. The important thing is that the exchange is optimised and that heat losses are kept to a minimum. It should be noted that the system is exactly the same, with a refrigerated liquid, in appliances such as air conditioners or refrigerators.

Depending on the heat exchanger used, the fluids can be of different natures. These include:

  •  Water
  • A heat transfer liquid
  • Air
  • Oil
  • Water vapour

There are several combinations such as:

  • Air and water
  • Air and air
  • Water and water
  • Oil and air
  • Oil and oil
  • Oil and water…

These fluids can also move in different ways and flow in counter-current, parallel current or cross-current. It should be noted that countercurrent and crosscurrent are most often used because they are known to be more efficient than co-current.

Heat exchanger in Bordeaux, Gironde: the basic principle

The heat exchanger consists of parallel networks in which fluids circulate. These fluids therefore have different temperatures. The networks in question are separated from each other by a wall made of a conductive material. The temperature difference between the two fluids is what allows heat exchange. Logically, the warmer fluid moves towards the colder fluid, to warm it up and thus lose its calories. When this fluid enters the heat exchanger hot, it heats the secondary fluid and leaves cooled.

It is therefore essential that the material of the heat exchanger offers optimal conductivity. Copper, aluminium, stainless steel or steel can be used to increase the efficiency of the heat exchange. These materials are also used in most systems such as water heaters, vehicle radiators, ventilation systems, fluid inertia radiators, air conditioners and boilers.
