Sell Corrugated tubes(finned tube)

Description

Corrugated tubes create extra turbulence in the fluid that flows through the tubes. This extra turbulence translates itself in a large increase in heat transfer compared to smooth tube heat exchangers. This extra heat transfer gives the following advantages:
More heat transfer means less heat transfer area needed.
Less area means shorter heat exchangers.
Shorter heat exchangers means a more economic design, money is saved.
Shorter length means a reduction in pressure drop. This saves pumping power and cost.
Shorter length means that the heat exchanger can be fitted in less space.

The extra turbulence created in the corrugated tube means that the unit can withstand longer the negative effects of fouling. With increasing flow velocity (or increased Reynolds number of the fluid) the effect of the corrugated tube becomes more apparent. The graph on the left illustrates this concept. In order to understand the basics and how a heat exchanger is made you can see the following animation. You can also see a simulation of a flow with particulates passing throgh a corrugated tube.
