Introduction of Heat Exchanger


We Jetvision offer kinds of heat exchanger parts, such as tube sheet, baffle plate, shell flange, u bent tube, vessel tank heads, fin tubes, u bend, etc.


Heat exchanger, is a device that transfers part of the heat from a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchanger is a common equipment in chemical, petroleum, power, food and many other industrial sectors, and occupies an important position in production. In chemical production heat exchangers can be used more widely as heaters, coolers, condensers, evaporators and reboilers, etc. There are many types of heat exchangers, but according to the principle of heat exchange between cold and hot fluids and the way basically can be divided into three categories, namely: between the wall type, mixed and thermal storage type. In the three types of heat exchangers, between the wall heat exchanger is the most used.


According to the principle of action can be divided into wall heat exchanger, heat storage heat exchanger and hybrid heat exchanger.

According to the purpose of use can be divided into cooler, heater, condenser and vaporizer.

According to the structure material can be divided into metal material heat exchanger and non-metal material heat exchanger.

According to the shape and structure of heat transfer surface can be divided into tube heat exchanger and plate heat exchanger.

According to the use can be divided into collective heating type heat exchanger and household heat exchanger.

1.Tube heat exchanger: fixed tube plate heat exchanger, floating head tube heat exchanger, tube box tube heat exchanger, floating coil type tube heat exchanger, etc.

2.Plate heat exchanger: equal cross-section, unequal cross-section plate heat exchanger, wide channel plate heat exchanger, narrow channel plate heat exchanger, brazed plate heat exchanger (part of the pressure vessel)

3.Spiral plate heat exchanger: detachable spiral plate heat exchanger and non-detachable spiral plate heat exchanger

4.Air heat exchanger (also called air cooler)

5.Volumetric heat exchanger

6.Tube-and-plate heat exchanger


Heat exchanger is an indispensable equipment for heat exchange and transfer in the process of chemical production. In petroleum, chemical, light industry, pharmaceutical, energy and other industrial production, often used as a low-temperature fluid heating or high-temperature fluid cooling, the liquid vaporization into steam or steam condensation into liquid. Heat exchanger can be a unit of equipment, such as heaters, coolers and condensers, etc.; but also a component of the process equipment, such as ammonia synthesis tower heat exchanger. Heat exchanger is an important unit of chemical production equipment, according to statistics, the tonnage of the heat exchanger accounts for about 20% of the entire process equipment some even up to 30%, its importance can be imagined.
