In recuperators, two media flow through simultaneously in a steady state. There is a partition between the media flows, which serves as a transfer surface. The heat is transferred indirectly from the hot medium to the partition and from the partition to the cold medium, without time lag.
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.
Stirred tank with double jacket and coil
Heating using jacket or coiled tube; stirrer for improved mixing of medium.
Finned tube heat exchanger
Heat transfer between water and air; cross-flow operation.
Cold water supply for the WL110 series as well as for devices with specific water supply requirements on the temperature.
Heat transfer in pipe flow
Heat exchanger with measurement of the fluid and wall temperature; operation in parallel flow and counterflow.
Heat transfer in the tubular heat exchanger
Heat transfer in pipe flows and determination of heat flux; parallel flow and counterflow operation.
Comparison of various heat exchangers
Comparison of plate heat exchanger, tubular heat exchanger, shell and tube heat exchanger, finned cross-flow heat exchanger, and stirred tank with double jacket and coiled tube.
Shell & tube heat exchanger steam/watert
Heat transfer process between steam and water, determination of heat flux of steam and water.
Heat transfer in air flow
Convective heat transfer using shell & tube and finned tube heat exchangers.
