Heat exchangers

Heat Cool Fin Industries offers Heat exchangers. They are used for transferring heat from one fluid to another through a separating wall. Heat exchangers can be classified according to the process of heat transfer, mechanical construction and principal material of construction. Following are some of the common type of heat exchangers: a. Double pipe heat exchangers - used particularly when the flow rates are low, and when the temperature range is relatively high. In this type, one fluid flows inside a pipe, while a second fluid flows either co-or-counter-currently m the annulus between a large pipe and the outer side of the inner pipe carrying the first fluid. b. Shell and tube heat exchanger - widely used, the equipment consists of a number of parallel tubes enclosed in a relatively close fitting cylindrical shell. One fluid flows inside the tube and is called the tube side fluid, the other flows outside the tubes and is called the shell side fluid. If none of the fluids condenses or evaporates the unit is known as a "heat exchanger". If one of the fluids, either in the tube or the shell condenses, the unit is known as a "Condenser" or as a heater, depending on whether the primary purpose of the unit is to condense one fluid or to heat the other. Similarly, if one of the fluid evaporates, the unit is designated as an "Evaporator" or as a "Cooler", depending on whether the primary purpose is to evaporate one fluid or to cool the other.
