Generally, a wire and tube heat exchanger uses the array of inline (symmetry) wires between both its sides, but this research used the array of staggered wires so that it decreases the resistance of convection heat transfer. The purpose of this research is to perform the modelling of single staggered wire and tube heat exchanger. Simulation used a finite element method with a MATLAB program assistance, which a heat exchanger is divided into some element units. To support the result of the modelling processed by MATLAB program, then the simulation analysis with CFD was done to perform the convection current dynamics on the outside surface of the heat exchanger. The model developed to present the heat transfer correlation on single staggered wire and tube heat exchanger was valid. The validation conducted by the approach of element temperature parameter on 9 points thermocouple with the error was less than 5% between the experimental and modelling results. From CFD analysis, it was obtained that the speed distribution of convection fluid current was averagely smoother and higher in the staggered heat exchanger, and it finally makes the convection heat transfer better.
