What is a spray heat exchanger?
In addition, in the casing heat exchanger, the two fluids can be pure countercurrent, and the logarithmic average driving force is larger. Casing heat exchanger structure is simple, can withstand high pressure, the application is also convenient
The tube outside the tube is a layer of high turbulence of the liquid film, the tube outside the heating coefficient is much larger than the immersion. In addition, most of this heat exchanger placed in the air circulation, cooling water evaporation is also taken away
This heat exchanger is the heat exchanger tube into the row of fixed in the steel frame, the hot fluid flow in the tube, the cooling water spray from the top of the device evenly under the shower, it is also known as spray cooler.
Part of the heat can play a lower cooling water temperature, increase the role of heat transfer force.Therefore, compared with the immersion, spray heat exchanger heat transfer effect greatly improved.
Casing Heat Exchanges Tubular heat exchangers are concentric bushings made of straight pipes of different diameters and are connected by U-shaped elbows. In this heat exchanger, a fluid tube In the casing heat exchanger, the two fluids can be pure countercurrent, and the logarithmic average driving force is larger.
