Abstract

In this paper, we use experiment to work on our own design of the dimple plate heat exchanger and the experimental result is compared with the heat transfer characteristics of the flat plate under the same experimental conditions.The test result shows that, under the given inlet temperature condition, heat transfer is closely related to Reynolds. At the low Reynolds number, the intensive heat transfer effect of dimple plate is not obvious. With the increase of Reynolds number, dimple plate’s wall heat transfer coefficient and heat transfer increase gradually, water outlet temperature gradually decrease, the flow resistance will also increase at the same time.The dimple plate has the effect of strengthening heat transfer, but also increases the resistance, in practical application process required to optimize the analysis, to find out a dimple plate with good matching effect between heat transfer enhancement and pressure loss.
