What are heat exchangers PDF?
A heat exchanger is a heat transfer device that exchanges heat between two or more process fluids. Heat exchangers have widespread industrial and domestic applications.
What is heat exchanger give detail classification of types of heat exchangers?
Heat exchangers are classified according to transfer processes into indirect- and direct- contact types. FIGURE 1.2 (a) Classification according to process function; (b) classification of condensers; (c) classification of liquid-to-vapor phase-change exchangers. exchanger as a regenerator.
What is 2/4 shell and tube heat exchanger?
Most shell-and-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to the number of times the fluid in the tubes passes through the fluid in the shell. Two and four pass designs are common because the fluid can enter and exit on the same side.
How many types of heat transfer are there?
Heat can be transferred in three ways: by conduction, by convection, and by radiation.
- Conduction is the transfer of energy from one molecule to another by direct contact.
- Convection is the movement of heat by a fluid such as water or air.
- Radiation is the transfer of heat by electromagnetic waves.
How many types of heat exchanger are usually used onboard vessels?
The two primary types of marine heat exchangers used aboard vessels in the maritime industry are plate, and shell and tube. Maintenance for heat exchangers prevents fouling and galvanic corrosion from dissimilar metals.
Do you know the different types of heat exchangers?
Types of Heat Exchangers Shell and Tube Heat Exchangers. The most common type of heat exchangers, shell and tube heat exchangers are constructed of a single tube or series of parallel tubes (i.e., tube Double Pipe Heat Exchangers. Plate Heat Exchangers. Condensers, Evaporators, and Boilers. Other Heat Exchanger Variants.
Which type of heat exchanger is more efficient?
The plate type heat exchanger is the most efficient type of heat exchanger with its low cost, flexibility, easy maintenance, and high thermal transfer. WCR plate corrugations are designed to achieve turbulence across the entire heat transfer area. This produces the highest possible heat transfer coefficients…
Which method is preferred for heat exchangers?
Directed energy deposition is preferred over other methods because of its ability to form free flowing structures without support material. Even though it is a costly manufacturing method, its build properties are unmatched by other manufacturing processes. Stainless steel is our preferred metal for the heat exchanger.
What are the different parts of a heat exchanger?
Heat Exchanger Parts SHELL. SHELL is the component of HE which keeps everything inside it. TUBES. TUBES are the second component that carries either hot or cold fluid. TUBESHEET. TUBESHEET is located on both sides of HE. BAFFLES. BAFFLES are used in the heat exchanger to increase the turbulence of shell-side fluid that increases the heat transfer coefficient.
