Why strengthen heat transfer of heat exchanger unit?

When the heat exchanger unit is turned on, it will soon feel a warm air, and heat exchange is flexible according to the ambient temperature. The heat exchange is very stable. Its heat exchange work is mainly operated through the heat transfer tube. In order to achieve higher heat exchange efficiency, heat transfer of heat exchanger unit should be strengthened.

The main methods to enhance heat transfer of heat exchange unit include:

One is to adopt the structure of enhanced heat transfer surface, such as:

1. The heat exchange unit adopts finned tube, nail head tube, threaded tube, bellows, etc.

2. The surface of heat exchanger tube group shall be machined: spiral ring tube, spiral groove tube, threaded tube, etc.

3. Using small diameter tubes can increase the number of tubes on the same tubesheet area and enhance the heat transfer area

Second, increasing the flow rate of fluid in the heat exchange unit can greatly improve its heat transfer coefficient, such as:

1. Add a spoiler, such as inserting a spiral belt into the tube of the heat exchange unit, and setting baffles and dummy tubes outside the tube.

2. Increase the number of tube side or shell side of heat exchange unit.

In addition, using materials with good thermal conductivity to manufacture heat exchangers, taking anti-corrosion and anti scaling measures for heat exchange units, and timely cleaning are all means to improve heat transfer effect.
