Titanium heat exchanger

Technology and Design The coiled tube bundle consists of circular layers of helically corrugated tubes placed inside each other. The fluid in each layer flows in the opposite direction to the layer surrounding it, resulting in an overall criss-cross pattern. The large number of tubes packed closely together give an extensive heat transfer surface within a light compact shell. The alternate layers provide rapid uniform heating of fluids increasing the overall heat transfer coefficient. Corrugated tubes produce a turbulent flow where the desired characteristic of fluctuating velocities is achieved. This random movement of fluid particles reduces deposit buildup by performing a "scoop and lift" action. The connection locations and angle of entry is specially selected to reduce the probability of debris buildup.
