Types Of Heat Exchanger And Its Application
The two main types are finned and unfinned tubular. Shell and tube heat exchanger.
Plate and shell heat exchanger.
Types of heat exchanger and its application. Types of Heat Exchangers The design concepts expressed above are practically expressed in the physical construction of a heat exchanger. A shell and tube heat exchanger is designed with a number of tubes placed inside a cylindrical shell. Adiabatic wheel heat exchanger.
Heat transfer is commonly encountered in many aspects of our life. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. Conduction Convection and Radiation according to the medium of solid or liquid or gas.
This is the most effective method of heat exchange. Counter-flow heat exchangers are designed to allow both the heated and cooling fluids to enter from opposite ends of the device. In the unfinned exchanger heat can be exchanged in all directions and the fluid can mix.
The main types are considered below. A heat exchanger is a system used to transfer heat between two or more fluidsHeat exchangers are used in both cooling and heating processes. Shell and tube heat exchanger plate heat exchanger tubular heat exchanger and fin type heat exchanger.
Plate fin heat exchanger. Shell and tube heat exchangers consist of series of tubes. Shell and tube plate and frame and tube and tube.
Many types of heat exchangers have been developed for use in steam power plants chemical processing plants building heat and. The popular design of this type of heat exchanger allows for a wide range of pressures and temperatures. TYPES OF HEAT EXCHANGERS Due to the different types of applications for heat exchanges different types of hardware and different configurations of heat exchanges are required.
541 Classification of Heat Exchangers The following types of heat exchangers are presently used in process industries. One set of these tubes contains the fluid that must be. 1 Dairy Plant Milk Chilling Plant- Plate Type Heat Exchanger Because It is made up of an aluminum alloy which.
ASME heat exchangers Automotive heat exchangers typically as car radiators Brewery heat exchangers Chemical heat exchangers Cryogenic heat exchangers Marine heat exchangers Power. The product flows through the inner tube while the service flows through the space between the two tubes. They are widely used in space heating refrigeration air conditioning power stations chemical plants petrochemical plants petroleum refineries natural.
Double pipe heat exchangers Figure 51 Shell and tube heat exchangers. The most prevalent application is tank jackets for beer and dairy tanks but sections of dimple plate can also be cut to fit inside a tank and submerged in the stored liquid for efficient heat transfer. This can be classified according to the process of heat transfer mechanical design and principal material of construction.
This has resulted to different designs of heart exchangers which includes and not limited to. Double pipe heat exchanger simplest heat exchanger. Regenerative Heat Exchangers This is a popular type of heat exchanger.
We try to c. Recuperators Recuperators are among the most widely used types of heat exchangers. With a finned tubular heat exchanger both fluids are unmixed the one between the fins is guided in a direction transverse to the tube flow direction.
2 The condenser of Refrigeration System- Counter Flow tube type heat exchanger. Finned tubes are generally produced by helically winding strip on to tubes Fig. Theory behind heat exchanger is applying Heat Transfer.
Heat exchangers have widespread industrial and domestic applications. Out of all the types of heat exchangers shell and tube heat exchangers are the most versatile. Broadly grouped the three major types of heat exchangers are.
Applications of heat exchangers. Generally there are four types of heat exchangers used for heat controlling. Evaporators are used in various processes including pharmaceuticals foods and beverages pulp and paper chemicals polymers and resins inorganic salts acids bases and many other things.
The heat exchange efficiency of the finning depends on good heat conduction across the joint between the fin and tube interfaces. The most common example is the human body which is constantly rejecting heat to its surroundings and human comfort is closely tied to the rate of this heat rejection. An evaporator consists of a heat exchanger valves manifolds controls pumps and condenser.
Evaporators used in automobile radiators and ice plants come under these types of heat exchangers. In heat exchanger applications stainless steel finned tubes are often required for the optimum design for a specific application. Parallel flow heat exchangers have a design that allows both the cool and heated fluids to move in the same direction.
The tube-in-tube heat exchanger also known as double tube heat exchanger is formed by two concentric tubes. Annular space heat exchanger. Several variants of heat exchangers are available and find application in a wide range of industries including.
Shell and Tube Heat Exchangers.
