The present set-up is designed to study the Plate type heat exchanger. It consists of a 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 fluids can be directed alternately into passages formed between the plates. The hot fluid enters at the top on the right side of the fixed end cover, flows downwards through alternate channels between the plates and leaves at the bottom. The cold fluid enters at the bottom of the left side of the fixed end cover, flows in counter current flow through alternate channels between the plates and leaves at the top. For hot water, a recirculating type water bath having PID temperature controller and a magnetic pump is provided. Cold water at constant head condition is to be provided from laboratory overhead tank. Flow rates are measured by using Rotameters. The temperature of hot and cold fluids at inlet and outlet of heat exchanger can be measured by Digital Temperature Indicator.
