. Double-pipe heat exchanger When one fluid flows through the smaller pipe, the other flows through the annular gap between the two pipes. These flows may be parallel or counter-flows in a double pipe heat exchanger. (a) Parallel flow, where both hot and cold liquids enter the heat exchanger from the same side, flow in […]

 heat exchangers are designed to maximize the surface area of the wall between the two fluids, while minimizing resistance to fluid flow through the exchanger. The exchanger’s performance can also be affected by the addition of fins or corrugations in one or both directions, which increase surface area and may channel fluid flow or...

There are three primary classifications of heat exchangers according to their flow arrangement. In 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. In counter-flow heat exchangers the fluids enter the exchanger from opposite ends. The counter current...

A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes.[1] The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact.[2] They are widely used in space heating, refrigeration, air conditioning, power...

A plate heat exchanger functions as a specialized device for transferring thermal energy between two fluid streams using a series of metal plates. One of its primary advantages over traditional heat exchangers lies in the substantial increase in surface area for heat exchange, achieved by spreading the fluids across these plates. This...

Cooling System Design Requirements The primary purpose of the engine cooling system is to reject heat from the jacket water coolant and auxiliary circuit if equipped, at greatest engine load, highest ambient temperature, and altitude. This section will outline the proper methods to be used for cooling system sizing. Heat Rejection Before a cooling...

Compressor Oil Coolers A compressor oil cooler (or other external heat load) should be connected into the after cooler circuit after the water has left the after cooler. The return line back into the circuit should be placed before the thermostat. If full flow is not needed to the compressor oil cooler, a bypass line […]

Two-Stage After cooler Cooling Systems The two-stage after cooler, currently offered for some gas engines, is intended to provide high temperature heat recovery for Electric Power Generation (EPG) applications and Reduce overall radiator sizing for Gas Compression applications. There are two coolant stages on the two-stage after cooler; the first...

Types of Cooling Systems • Radiator • Heat Exchanger • Submerged Pipe • Cooling Tower • Keel & Box Coolers • Seawater Systems • Electrochemical Series

All internal combustion engines produce heat as a byproduct of combustion andfriction. This heat can reach temperatures up to 1925°C (3500°F) and can havecatastrophic effects on engine components. Pistons, valves and cylinder headsmust be cooled to reduce the risk of detonation. Cylinder temperatures need to becontrolled so lubricating oil can...

Working Principles of Heat Exchanger Heat exchanger functions by transferring heat from higher to lower temperatures. Heat can thus be transferred from the hot fluid to the cold fluid if a hot fluid and a cold fluid are separated by a heat-conducting surface. The operation of a heat exchanger is governed by thermodynamics. Heat can […]

Common materials used in heat exchangers Selecting the materials used in a heat exchanger is a pivotal part of the design. They need to be heat conductive whilst withstanding any corrosive properties of the mediums involved. Some materials will wear or get dirty faster than others, so upkeep and durability is another consideration. Conductive...

Other types of tubular exchanger include: Air Cooled Heat Exchangers consist of bundle of tubes, a fan system and supporting structure. The tubes can have various type of fins in order to provide additional surface area on the air side. Air is either sucked up through the tubes by a fan mounted above the bundle (induced […]

A Shell and Tube Exchanger consists of a number of tubes mounted inside acylindrical shell.  typical unit that may be found in a petrochemicalplant. Two fluids can exchange heat, one fluid flows over the outside of thetubes while the second fluid flows through the tubes. The fluids can be singleor two phase and can flow in […]

Heat Exchanger Types   This section briefly describes some of the more common types of heat exchanger and is arranged according to the classification Indirect heat exchangers   In this type, the steams are separated by a wall, usually metal. Examples of these are tubular exchangers, plate exchangers, Tubular heat exchangers are very...

Recuperative heat exchangers   There are many types of recuperative exchangers, which can broadly be grouped into indirect contact, direct contact and specials. Indirect contact heat exchangers keep the fluids exchanging heat separate by the use of tubes or plates etc. Direct contact exchangers do not separate the fluids exchanging heat and in...

Regenerative heat exchangers In a regenerative heat exchanger, the flow path normally consists of a matrix, which is heated when the hot fluid passes through it (this is known as the “hot blow”). This heat is then released to the cold fluid when this flows through the matrix (the “cold blow”). Regenerative Heat Exchangers...

Classification of Heat Exchangers by Construction heat exchangers are classified mainly by their construction, The first level of classification is to divide heat exchanger types into recuperative or regenerative. A Recuperative Heat Exchanger has separate flow paths for each fluid and fluids flow simultaneously through the exchanger...

Cross flow heat exchangers are intermediate in efficiency between counter current flow and parallel flow exchangers. In these units, the streams flow at right angles to each other

In co current flow heat exchangers, the streams flow parallel to each other and in the same direction This is less efficient than counter current flow but does provide more uniform wall temperatures. Process 1. Process fluid assignments to shell side or tube side. 2. Selection of stream temperature specifications. 3. Setting shell side and...

Counter flow exchanger in which the two fluids flow parallel to each other but in opposite directions. This type of flow arrangement allows the largest change in temperature of both fluids and is therefore most efficient (where efficiency is the amount of actual heat transferred compared with the theoretical maximum amount of heat that can...

A heat exchanger is a device used to transfer heat between two or more fluids. The fluids can be single or two phase and, depending on the exchanger type, may be separated or in direct contact. Devices involving energy sources such as nuclear fuel pins or fired heaters are not normally regarded as heat exchangers […]

Tube metal is usually: Low carbon steel Low alloy steel Stainless steel Copper Admiralty Cupronickel Inconel Aluminum (in the form of alloys), or titanium. Tube diameters (8–15 mm) are preferred for greater area/volume density but are limited, for purposes of in-tube cleaning larger tube diameters are often required for condensers and boilers....
