Abstract
An experimental study on the flow distribution characteristics according to the inlet direction of the working fluid and an analytical study on the flow characteristics according to the variation of the outlet width were carried out in order to present the optimal design of welded plate heat exchanger. In the experiment results on the flow distribution according to the inflow direction of the working fluid, the flow distribution in the welded plate heat exchanger is mainly formed around the center channel. As the inflow flow rate increases, the flow distribution ratio at the center channel decreases, whereas the flow distribution ratio at the side channel increases, thereby improving the distribution effect. The increase inflow rate of working fluid brings the incre of the pressure drop in the channel while the increase in width at the outlet reduces the pressure drop. Besides, it can be seen the dead zone where the fluid flow stagnates at the opposite corner of the outlet side.
