SEMINAR ON HEAT EXCHANGER:

SEMINAR ON HEAT EXCHANGER PRESENTED BY: PANKAJ KUMAR 6309342(D2) GURU NANK INSTITUTE OF TECHNOLOGY, AMBALA

CONTENTS:

CONTENTS INTRODUCTION TYPES OF HEAT EXCHANGER MODES OF HEAT TRANSFER ADVANTAGE DISADVANTAGE APPLICATION

INTRODUCTION:

INTRODUCTION The equipment used to transfer a heat is known as heat exchanger. Heat exchanger: they are the devices used for transferring heat from one fluid to another fluid through a metal wall. Example: Intercooler and preheaters Condensers and boilers Regenerators Automobile radiators etc.

TYPES :

TYPES 1.According to nature of heat exchange process Direct contact heat exchanger Indirect contact heat exchanger 2. According to relative direction of fluid motion Parallel flow Counter flow Cross flow

PowerPoint Presentation:

3. Acc. To design and constructional feature Double pipe heat exchanger Shell and tubes Multiple shell and tube passes Compact heat exchanger

DIRECT CONTACT HEAT EXCHANGER:

DIRECT CONTACT HEAT EXCHANGER Here heat exchange take place by direct mixing of hot and cold fluid. Example: Cooling tower Jet condenser INDIRECT CONTACT HEAT EXCHANGER Here heat transfer between two fluids could be carried out by transmission through wall . Regenerators Surface exchangers
