This paper conducted a preliminary design of heat exchanger based on helical baffles technique. The realizable k-ε turbulent model was adopted to simulate the flow properties and heat transfer in the shell side with the computational fluid dynamics software. The numerical results show that the helical baffles heat exchanger offer about 11% higher heat transfer coefficient, 6% higher pressure drop and 10% lesser heat exchanger area than of heat exchanger with segmental baffles under the same heat exchanger power. It could help achieve the goal of reducing volume of heat exchanger with helical baffles technique.
