Shell and Tube Evaporator Introduction:

The shell of the shell and tube condenser is a large cylinder made of steel plate of the container. The two ends are welded with round tube plates. The tube plates are drilled with many small holes. Each corresponding small hole is equipped with a copper tube. The connection of the tube sheet can be sealed and fixed by tube expansion or welding.

Both ends of the tube sheet are equipped with cast money end caps, and the end caps are cast with water dividers to divide the cooling water into many back and forth flow processes to change the cooling water flow rate and increase the heat transfer effect.

In this way, there are two separate spaces in the condenser, that is, a space composed of the tube sheet, the outer wall of the condenser tube and the inner wall of the cylinder. The refrigerant flows; the inner wall of many tubes and the two end caps of the water chamber The space formed by the flow is cooling water.

The rear end cover of the cylinder has a water inlet and a drain hole respectively, and the cooling water enters through the lower hole and discharges from the upper hole. The cylinder body is welded with refrigerant inlet and outlet pipes. The refrigerant vapor enters the steam inlet pipe at the upper part of the cylinder body, and contacts the outer wall of the condenser tube in the cylinder. The temperature drops and gradually condenses into liquid, drips into the lower part of the container and settles. Output from the outlet pipe.

There are two drain heads at the bottom of the front cover of the evaporator. When the refrigeration equipment is not in use in winter, the cooling water accumulated in the condenser should be installed and drained to avoid freezing and cracking of the cooling tube. Shell and tube condensers are widely used in small and medium-sized refrigeration equipment, and can be made into horizontal and vertical types. Its advantages are compact structure and good condensation effect.

Unit Characteristics:

1. The shell and tube evaporator is made of double-sided reinforced heat transfer tubes.

2. The shell-and-tube evaporator uses high-quality copper tubes with large diameter, large flow and high heat dissipation coefficient.

3. The shell and tube type evaporator has the advantages of high efficiency, energy saving, small size and sufficient energy, long life and easy cleaning.

4. Since the shell and tube evaporator is designed as a horizontal type, it is very convenient to maintain.

5. All evaporators have tested water pressure and air pressure before leaving the factory. No worries for customers.

6. The shell and tube evaporator can use red copper tube, navy copper, nickel copper tube, ordinary copper tube, etc. according to different media
