Have you seen these 4 kinds of high efficiency heat exchangers?

September 9, 2021

Latest company news about Have you seen these 4 kinds of high efficiency heat exchangers?

The high-efficiency heat exchanger mainly breaks the fluid laminar bottom layer on the inner and outer sides of the pipe through the special shape of the pipe to enhance the heat transfer efficiency. Compared with the ordinary tube heat exchanger, the efficiency is improved. Let's take a look at these efficient heat exchangers

 

Bellows high efficiency heat exchanger

The heat exchange tube of corrugated tube high-efficiency heat exchanger is a corrugated special tube inside and outside the tube. The convex corrugated surface inside and outside the bellows makes the fluid in the boundary layer produce vortex. The vortex continuously mixes the fluid in the boundary layer with the fluid outside the boundary layer, and the heat transfer coefficient inside and outside the bellows is greatly improved, which greatly improves the heat transfer efficiency of the heat exchanger.

T-shaped grooved tube high efficiency heat exchanger

The heat exchange tube of T-shaped grooved tube high efficiency heat exchanger is a special tube with smooth tube as blank tube, spiral T-shaped fins are processed on the outer surface of the heat exchange tube, and there is an inner extended cavity between the fins. The T-groove structure can not only provide a stable vaporization core for the fluid in the inner expansion cavity, but also make the boiling fluid outside the tube form a thin liquid film on the tunnel wall, effectively strengthen the boiling heat transfer coefficient outside the tube, and greatly improve the heat transfer efficiency of the heat exchanger.

Inner grooved tube high efficiency heat exchanger

The inner grooved tube of the inner grooved tube high efficiency heat exchanger is a special tube with a smooth tube as the blank tube and machined into a linear or spiral groove on the inner surface of the heat exchange tube. The groove structure provides a stable vaporization core for liquid vaporization. The thin liquid film formed by the fluid in the groove can be evaporated rapidly, which effectively strengthens the heat transfer coefficient in the tube, so as to greatly improve the heat transfer efficiency of the heat exchanger.

Twisted tube high efficiency heat exchanger

The twisted tube of twisted tube high-efficiency heat exchanger is processed by special machine tool with smooth tube as blank tube. When the fluid flows longitudinally in the twisted tube, a secondary swirl perpendicular to the mainstream direction is generated, which greatly improves the synergy of velocity field and temperature field; When the assembled tube bundle and shell side fluid flow through the spiral channel formed between the heat exchange tubes, the velocity and direction are periodically changed under the action of centrifugal force, and the wake separated from the tube wall is formed after passing through the contact point, which increases the turbulence degree of the fluid. Under the joint action of fluid inside and outside the twisted tube to enhance heat transfer, the heat transfer efficiency of the heat exchanger is greatly improved.
