2. CONTENT
• INTRODUCTION
• VARIOUS TYPE OF HEAT EXCHANGERS
• EQUIPMENTS USE AND THEIR SPECIFICATION
• OBJECTIVE
• CONCLUSION

3. INTRODUCTION
HEAT TRANSFER :-
HEAT TRANSFER IS ENERGY TRASFER DUE TO
TEMPRATURE DIFFERANCE
• DIFFERENT HEAT TRANSFER MODES:-
THERE ARE THREE TYPES OF HEAT TRANSFER
MODE:-
1. CONDUCTION
2. CONVECTION
3. RADIATION

4. HEAT EXCHANGER
• HEAT EXCHANGER:-
HEAT EXCHANGER IS USE FOR EXCHANGE OF HEAT
FROM ONE FLUID TO ANOTHER FLUID.
THERE ARE TWO TYPES OF FLOW POSSIBLE INTO THE
HEAT EXCHANGER
1. CO-CURRENT FLOW
2. COUNTER CURRENT FLOW

6. • VARIOUS TYPE OF HEAT EXCHANGERS
1. DOUBLE PIPE (CONCENTRIC PIPE) HEAT EXCHANGER
2. PLATE HEAT EXCHANGER
3. SHEEL AND TUBE HEAT EXCHANGER
• DOUBLE PIPE HEAT EXCHANGER:-
THIS TYPE OF HEAT EXCHANGER
CONSIST OF TWO CONCENTRIC
PIPE IN WHICH TWO
DIFFERENT TEMPRATURE
FLUID FLOWS IN CO-CURRENT
AND COUNTER CURRENT
FLOW.

7. PVC PIPE:-
(Length 2 feet & diameter 0.45
feet)
BALL VALVES:-
(To control the flow of inlet and
outlet pipe)
EQUIPMENT AND THEIR
SPECIFICATION

8. ALUMINUM PIPE
(Length slightly more than 2 feet
and diameter 0.085 feet)
SUBMERSIBLE PUMPS

9. PVC PIPE CAPS
INLET OUTLET PIPE
Capacity to holding hot water 80°C

10. OBJECTIVE
1. LMTD(LOG MEAN TEMPERATURE DIFFRANCE)
2. TEMPERATURE VARIATION BY GRAPH
3. OVERALL HEAT TRANSFER COFFICIENT

11. CONCLUSION
• Double pipe heat exchanger design is rather straight
forward . It is use one pipe inside another .after
determining the required heat exchanger surface area
for either counter flow of parallel flow , the pipe sizes
and number of bends for the double pipe heat exchanger
can be selected .
• With the help of our design we would find out the LMTD ,
Temperature variation graph and overall heat transfer
coefficient
