At present, shell and tube heat exchanger is the most widely used heat exchanger. Shell and tube heat exchangers are compact in structure
The transfer strength and metal consumption per unit heat transfer area cannot be related to plate or finned heat exchangers
But it has a wide range of working temperature and pressure, low manufacturing cost, convenient cleaning, large processing capacity and reliable work.
Shell and tube heat exchangers produced by our company include cooler, heater and condenser.
Shell and tube changeover appliances have the following characteristics:
1. Good sealing performance,
2. Eliminate leaks
3. High heat exchange efficiency
4. Easy maintenance
5. Long corrosion life, etc.
The cooler is composed of the following parts (see Figure 1): Transmission principle: transmission of two fluids, namely, transmission of liquids and cold liquids
Flow in the pipeline, called pipeline fluid; Another type of flow outside the pipe is called the shell - in order to raise the flow outside the pipe
Heat transfer coefficient, usually installed in the housing several baffles, the baffles can increase the velocity of the fluid side of the housing, forcing the fluid
The changeover tube can be arranged on the tube plate according to equilateral triangle or square, and equilateral triangle is arranged compact
High turbulivity, high transmission coefficient. Dry clean the outside of the pipe, and suitable for drying easily scaled fluid
