DESCRIPTION:
Plate type heat exchanger consists of frame in which independent metal plates are clamped between a head and follower. The plates are sealed at their outer edges and around the ports by gaskets, which are so arranged that the liquid and the heating/cooling media are directed alternately into passages formed between the plates. The hot fluid enters at the top on the right side of the fixed end cover and flows downwards through alternate channels between the plates. The Hot fluid leaves the exchanger through a connection at the bottom of the fixed end cover. The cold fluid enters at the bottom of the left side of the fixed end cover. The cold fluid flows in counter current flow through alternate channels between the plates and leaves the exchanger at the top on the left side of the fixed end cover.
The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Lab view of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by “Lab Smith” This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.
