Essentially the role of heat exchangers is to transfer the heat of a flowing material to another flowing material with a lower starting temperature. The materials can be gaseous or liquid. The temperature difference between the two media as the driving differential is essential for heat transfer.
Heat exchanger supply unit
Measuring the transfer characteristics of four different heat exchanger models.
Tubular heat exchangers
Transparent heat exchanger with additional temperature measuring point after half of the transfer section; parallel flow and counterflow operation.
Plate heat exchanger
Typical plate heat exchanger in parallel flow and counterflow operation.
Shell & tube heat exchanger
Transparent shell and tube heat exchanger in cross parallel flow and cross counterflow operation.
Finned tube heat exchangerl
Heat transfer between water and air; cross-flow operation.
