The plate type heat exchanger is widely used in industries as it has an advantage of its high heat transfer efficiency and compactness. Numerical analysis is performed on the effect of inner flow characteristics, i.e., the temperature distribution and the pressure drop inside the plate type heat exchanger. Here a commercial numerical analysis program ANSYS CIX V14.0 is employed to examine the inner flow pattern of a detachable Herringbone pattern which has a complicated and small flow space. Also, the temperature distribution and the pressure drop are verified. Based on this, there is an improvement of inner pattern, decrease of pressure drop amount and the increase of heat transfer. This can be used as basic material to design the plate type heat transfer of detachable Herringbone pattern in the future.
