The paper introduces geometric form and flow mechanism in spiral baffled heat exchanger, In the present work, the current development of heat transfer and pressure drop with spiral baffles are reviewed. Compared to the conventional segmental - baffle heat exchanger, the spiral baffled heat exchanger has relatively higher heat coefficient, and lower pressure drop . transfer mechanism and effects of baffle. The research focal point in the future lies in flow and heat transfer mechanism and effects of baffle.
