TH72104A - Tube and plate fin type heat exchanger - Google Patents

Abstract

DC60 (18/08/47) This invention is a tube and plate-fin heat exchanger, consisting of a number of fins stacked together. They are set apart from each other and a number of heat exchanger tubes 2 insert into fin 1 in the direction where the fins are stacked together. The heat exchanger is designed to perform heat exchanger between the flowing fluid. Inside And outside of the heat exchanger tube 2 and through the heat exchanger tube 2 and fin 1 respectively.Each fin 1 has a number of convex protrusions 3 with a composite bridge shape. With a leg and a floating platform The cut and rolled sections 3 work together with each heat exchanger tube 2, which is generated only in the region of the fin that has the following relationships: Ws = (1 - (formula )) Dp + (formula) D (formula)> 0.5 Ws is the radiated width of the cut part and the roll is raised in the direction. (Direction of upright row) that continues along one end of the fin on the upward side of the second fluid, D is the outer diameter of the heat exchanger tube, Dp is the distance along the line of the exchanger tube - Change the heat in the direction of the vertical row. The invention is the right tube and plate heat exchanger, consisting of a number of fins stacked together. They are set apart from each other and a number of heat exchanger tubes 2 insert into fin 1 in the direction where the fins are stacked together. The heat exchanger is designed to perform heat exchanger between the flowing fluid. Inside Exchanges outside of heat exchanger tubes 2 and through heat exchanger tubes 2 and fin 1, each fin sequence 1 has a number of protruding protrusions 3 with a composite bridge shape. With a leg and a floating platform The cut and rolled sections 3 work together with each heat exchanger tube 2, which is generated only in the region of the fin that has the following relationships: Ws = (1 - (formula )) Dp + (formula) D (formula)> 0.5 Ws is the radiated width of the cut part and the roll is raised in the direction. (Direction of upright row) that continues along one end of the fin on the upward side of the second fluid, D is the outer diameter of the heat exchanger tube, Dp is the distance along the line of the exchanger tube - Change the heat in the direction of the vertical row.
