Heat exchanger classification
|
|
The heat exchanger classification heat exchanger, as heat transfer equipment everywhere, in the industry application very popular, especially large energy field, with energy saving technology rapid development, the heat exchanger
Class more and more, suitable for different medium, the different condition and different temperature and pressure of different heat exchanger and its structure is not the same type, type heat exchanger with the new type, efficient heat transfer
The development is constantly updated, specific classification as follows:
A, according to the principle classification:
1, the direct contact heat exchanger
This kind of heat exchanger is the main principle of two kinds of medium and transfer heat through contact each other, realize the heat transfer, the contact area directly affects the quantity of heat, this kind of heat exchanger media usually
A is a gas, another for liquid, are based on the tower of the main body of the equipment for the heat transfer equipment, but usually involved and mass transfer, so it is difficult to tell and the relationship between the tower, usually for tower etc
Equipment, power plants use cool water tower for the most typical of the direct contact heat exchanger.
2, energy storage type heat exchanger (hereinafter referred to as the accumulator)
This kind of heat exchanger dosage is few, principle is hot medium by heating the first solid material to a certain temperature, cold media again through the solid material is heating, make to the heat
Purpose.
3, between the mural type heat exchanger
This kind of heat exchanger dosage is very large, accounting for over 99% of the total, principle is hot media through the metallic and non-metallic will give cold heat transfer medium, this kind of heat exchanger we usually called tubular plate, fin type or plate heat exchanger.
Second, according to the heat transfer species classification
1 no phase change, heat transfer
Generally fall into the heater and cooler.
2, a phase change heat transfer
Generally divided into condenser and heavy boiling device. Heavy is divided into kettle boil and boil in heavy machine, siphon type heavy boiling device, reboiler, evaporator, steam generator, waste heat boiler.
Three, heat transfer components according to the classification
1, tubular heat transfer components
(1) handling hypoxia type heat exchanger
(2) fixed tube plate heat exchanger
(3) the stuffing box type heat exchanger
(4) "U" pipe heat exchanger
(5) the snake tube heat exchanger
(6) double shell heat exchanger process
(7) single casing heat exchanger
(8) casing heat exchanger
(9) the diversion tube heat exchanger
(10) baffle pole type heat exchanger
(11) heat pipe heat exchanger
(12) intubation type heat exchanger
(13) sliding tube plate heat exchanger
2, plate type heat transfer components
(1) spiral plate heat exchanger
(2) plate heat exchanger
(3) fin type heat exchanger
(4) plate heat exchanger
(5) board type evaporator
(6) plate condenser
(7) printed circuit board plate heat exchanger
Four, nonmetal materials heat exchanger classification
(1) graphite heat exchanger
(2) fluorine plastic heat exchanger
(3) ceramic fiber composite materials heat exchanger
(4) glass fiber reinforced plastic heat exchanger
Five, the air cold heat exchanger classification
(1) the dry air condenser
(2) the wet air condenser
(3) dry wet joint air condenser
(4) power station air condenser
(5) surface evaporation air condenser
(6) board type air condenser
(7) energy recycling air condenser
(8) natural convection air condenser
(9) high pressure air condenser
(10) perforation plate heat exchanger
Six, according to heat transfer enhancement component classification
(1) thread tube heat exchanger
(2) the corrugated pipe heat exchanger
(3) irregular pipe heat exchanger
(4) the surface porous tube heat exchanger
(5) spiral flat tube heat exchanger
(6) spiral groove tube plate heat exchanger
(7) ring groove tube heat exchanger
(8) the slot tube heat exchanger
(9) around the spiral pipe heat exchanger
(11) T finned tube heat exchanger
(12) new structure efficient heat exchanger
(13) interpolation content heat exchanger
(14) serrated tube heat exchanger
The heat exchanger sort is various, and according to the classification of box, etc, all kinds of heat exchanger with a kind of use their conditions and therefore should be based on the medium, temperature, pressure, use different occasions
Choose different kinds of heat exchanger, effectively, bring the more economic benefit.
