1. ASSIGNMENT TOPIC HEAT EXCHANGER NAME : TUSHAR MEHTAR SHAHARE COLLEGE OF DAIRY TECHNOLOGY UDGIR MAHARASHTRA PRESENTATION PPT

2. INTRODUCTION > A Heat Exchanger. May be defined as device which Mechanical transfer the heat from Hot fluid to cold fluid. > Hydraulic Oil Cooler or example will remove heat from hot oil by using cold water or air. 

3. EXAMPLE OF THE HEAT EXCHANGER 1.Cooling center 2.Milk chilling center 3.Evoporator 4.Condenser 5.Boiler Plant 6.Radiator.

4. PRINCIPAL OF HEAT EXCHANGER Heat transfer of hot fluid to cold fluid Heat transferred through the wall Q= U.A. (LMTD) • H eat naturally flow from higher temperature to lower temperature .

5. • Shell and tube = most are commonly used in chemical process •Plate and Frame = Air cooler Types of Heat Exchangers

6. FLOW ARRANGEMENT Parallel flow heat exchangers = parallel-flow heat exchangers, the two fluids enter the exchanger at the same end, and travel in parallel to one another to the other side.

7. FLOW. ARRANGEMENT Cross-flow heat exchangers > In a cross flow heat exchanger. the fluids travel roughly perpendicular to one another through the exchanger.

8. FLOW ARRANGEMENT • In counter-flow heat exchangers: T he fluids enter the exchanger fromopposite ends. The counter current design is the most efficient.

9. TYPES OF HEAT EXCHANGERS 1. Plate heat Exchanger 2. Shell and tube Heat Exchanger 3. Double pipe heat Exchanger 4. Adiabatic wheal heat Exchanger 5. Spiral. Heat Exchanger 6. Fluid Heat Exchanger 7. Waste recovery unit

10. SHELL AND TUBE HEAT EXCHANGER Shell-and-Tube Heat Exchangers are the most important type of Heat Exchangers. It is used in almost every type of industry. This type of heat exchanger consists of a set of tubes in a container called a shell. The fluid flowing inside the tubes is called the tube side fluid and the fluid flowing on the outside of the tubes is the shell side fluid.

11. SHALL AND TUBE HEAT EXCHANGER APPLICATION •Cooling and hydrolic Fluid • Heated Liquid cool • Engine oil cooling

12. PLATE AND FRAME HEAT EXCHANGER A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids . A plate-fin heat exchanger is a type of heat exchanger design that uses plates and finned chambers to transfer heat between fluids .

13. PLATE HEAT EXCHANGER APPLICATION Water Heaters Cooling tower isolation Free cooling Thermal storage system Heat pump Isolation.

14. ∆ PLATE HEAT EXCHANGER.

15. DOUBLE PIPE HEAT EXCHANGER >Two sets of concentric pipes, two connecting tees, and a return head and a return bend. >A device whose purpose is the transfer of thermal energy between two fluids. >Common applications: Boilers, Coolers, Condensers, Evaporators.

16. DOUBLE PIPE HEAT EXCHANGER APPLICATION Pasteurization Digester heating Free heating Heat recovery
