TH37273B - Tube and plate fin type heat exchanger - Google Patents

Abstract

DC60 (18/08/47) This invention is a tube and plate fin type heat exchanger which consists of a number of fins 1 stacked together. They are located at a specified distance from each other and a number of heat exchanger tubes 2 insert into fin 1 in the direction of the fins being stacked. This heat exchanger is designed to exchange heat between the flowing fluids. inside and on the 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 protrusions 3 forming a bridge assembled. with the legs and the floating platform The cut and raised sections 3 work together with each heat exchanger tube 2. This section is created only in the fin region with the following relation Ws = (1 - (formula )) Dp + (formula) D (formula) > 0.5 Ws is the spreading width of the cut and raised section in the direction of D is the outer diameter of the heat exchanger tube, Dp is the distance along the exchanger tube. Change the heat in the direction of the vertical row. This invention is a tube and plate fin type heat exchanger which consists of a number of fins 1 stacked together.
