Heat exchanger

A heat exchanger is a device used to transfer heat between a solid object and a flui or between two or more fluids. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, . It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications.

As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of . An easy-to-understand introduction to how a heat exchanger passes heat energy from one fluid (liquid or gas) to another.

Their compact stainless steel construction makes them an . The fluids can be single or two phase an 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. Tranter heat exchangers share one thing in common—heat transfer through plates instead of tubes. Turbulent flow at low velocity produces high heat transfer efficiency and low fouling.

The module covers a variety of procedures concerning different types of heat exchanges within the oil refinery. Plate exchangers conserve . Heat exchanger definition, a device for transferring the heat of one substance to another, as from the exhaust gases to the incoming air in a regenerative furnace.

Alternatively, the fluids may be in cross flow (perpendicular to each other), as shown by the finned and unfinned tubular heat exchangers of Figure 18. The two configurations differ according to whether the fluid moving over the tubes is unmixed or mixed. Classification of heat exchangers. Transfer of heat from one fluid to another is an important operation for most of the chemical industries. The most common application of heat transfer is in designing of heat transfer equipment for exchanging heat from one fluid to another fluid.

Such devices for efficient transfer of heat are . New Lower Price, Same Respected Quality. At ABC, we are constantly striving to reduce costs without compromising quality. The heat exchanger exchanges heat between a heat source and a fluid. It is usually used together with a nuclear reactor and steam turbines.

Shell and Tube Heat Exchanger. In extreme cases, high pressure may impose limitations by . The solution of this problem leads to linear dimensionless temperature distributions. The temperature distributions for fluids and are NTU,? Copper brazed plate heat exchangers provide efficient heat transfer with a small footprint. They are maintenance free, provide a long service lifetime and can withstand high temperatures and extremely high design pressures.

They are used in a range of duties including cooling, heating, evaporation and condensing. Customers looking for a single coil or a million, custom- designed coils, look to Modine.
