Title:
PLATE-TYPE HEAT EXCHANGER HAVING STRUCTURE FOR MITIGATING HEAT-SHOCK
Document Type and Number:
WIPO Patent Application WO/2012/015179
Kind Code:
A2
Abstract:
A plate-type heat exchanger having a structure for mitigating heat-shock of the present invention can mitigate stress concentration from heat shock and fatigue stress, thereby lengthening the lifespan of a product and promoting safety in various industrial systems using the heat exchanger. The plate-type heat exchanger for heat exchanging between fluids by having a plurality of heating panels that are stacked inside a frame, and an upper lining and a lower lining on the upper and lower surfaces of the heating plates, comprises: columns, which respectively couple to the four corners of the inside of the frame, are formed in the shape of a rectangular prism, and are welded together between the upper lining and the lower lining, wherein the corners which are arranged close to the heating plates are eliminated along the length direction to form buffering surfaces; column liners, which are extendedly formed along the length direction of the columns, having one side provided with a plurality of grooves into which vertexes of the stacked heating plates are inserted and coupled, and having another side which spreads apart to couple to two sides of the columns, wherein the column liners are separated apart from the buffering surface of the column to form a buffering space therebetween; and stress dispersing means for dispersing stress, generated when the heating plates expand due to heat, which are respectively formed on the plate surface of the upper lining and the lower lining.
