Coaxial heat exchanger Supplier Soundhon
tube heat exchanger is made of different diameters of straight pipe made of concentric casing, and connected by U-shaped elbow. In this heat exchanger, a fluid go tube, another fluid go ring gap, both can get a higher flow rate, so the heat transfer coefficient is larger.
In addition, in the casing heat exchanger, the two fluids can be pure countercurrent, logarithmic average driving force is larger. Casing heat exchanger structure is simple, can withstand high pressure, the application is also convenient (according to the need to increase or decrease the number of tube sections).
In particular, due to the fact that casing heat exchangers also have a large heat transfer coefficient, a large heat transfer drive and the ability to withstand high pressures, almost all heat exchangers used in ultra-high pressure production processes (e.g. high pressure polyethylene production processes with an operating pressure of 3000 atm) are tube.
Tube heat exchanger (3 sheets) Heat exchanger with an inner tube in a concentric casing as the heat transfer element. Two different diameters of the tube set together to form a concentric casing, each section of the casing called “a process”, the process of the inner tube (heat transfer tube) to borrow U-shaped elbow tube, while the outer tube with a short tube connected in turn into a row, fixed in the bracket (Figure a). Heat is transferred from one fluid to another through the walls of the inner tube.
