LNG Plate for small LNG ship heat exchanger

摘要

The present invention relates to a heat exchanger heat exchanger plate for a small LNG ship, in the heat exchanger heat exchanger plate for a small LNG ship, the heat transfer plate is a plate end shell-type rectangular heat exchanger plate, an inlet for forming a flow path and a herringbone pattern, respectively. , The rectangular heat exchanger plate is made of 0.4t ~ 0.7t stainless steel material by using a press of a constant size to continuously stamp the same shape brazing is carried out, the flow path forming inlet hole is, It is formed in two adjacent to the upper and lower or left and right end portion has a considerable length between the flow path forming inlet hole to improve the heat exchange efficiency by alternately smoothly distributing the heating fluid and the heated fluid to each other, the herringbone pattern is Fluid is evenly distributed on the plate, creating turbulent flow, By providing a small heat exchanger heat exchanger plate for a small LNG ship, characterized in that it is press-molded so that the direction of the pattern is arranged diagonally so as to generate it, so that the equivalent length and heat transfer area of the plate for a DF engine gas fuel supply system vaporizer used in a small LNG ship etc There is an effect that can increase the heat exchange efficiency by increasing the.;
