Heat exchanger

Bringing heat from one medium to another

The heat exchanger, also called heat transmitter, is a technical device for the transition of thermal energy from one medium to another.

In general heat exchangers can be divided into 3 different classes.

The most frequent form is indirect heat transition. Here, substance flows are spatially separated, so that commingling of media cannot occur.

Even a direct transition of thermal energy in-between the media is possible. In this procedure both media are in direct contact, they intermingle, thus providing a correct balance of energies.

The combination of both procedures is semi-indirect heat transition.

Here, both media are timely separated from each other and conducted through a heat exchanger. Thermal energy is buffered inside the heat storage unit and is then absorbed by the subsequently passing medium.

Moreover, there is the possibility to influence heat transition by means of the flow direction/guiding. In practice, mostly transitions are applied according to the cross-flow and parallel flow principle.

Uniflow principle means that the media run parallel to one another. Due to the uniform flow direction the substances adjust their temperature in a homogeneous way. Above all, his is necessary for a safe and rapid cooling.

At the cross-flow principle In contrast, media bypass In opposite direction to one another. A high level of efficiency of the heat exchanger makes it possible to bring the cooler substance nearly to the inlet temperature of the hotter medium. A typical example for this procedure is heat recovery.

Thanks to its wide range of application, it is possible to design heat-exchangers for different kinds of substances. Whether the transition between liquid or gaseous media or whether the combined transition from a liquid onto a gaseous substance is required, MainTech Systems possesses enough capacities to guide your energy- and substance flows on the right track.
