Abstract

The invention relates to a welded plate heat exchanger, and more specifically relates to a welded plate heat exchanger with a structure for preventing heat damage caused by welding. The welded plate heat exchanger is characterized in that the welded plate heat exchanger comprises a heat exchange portion formed by the lamination of a plurality of plates, a shell for containing the heat exchange portion in the inner part, a first inlet portion, and a second inlet portion, a first flow-into side opening portion and a second flow-into side opening portion are respectively formed at two opening ends of the shell, the shell is provided with a first discharge side opening portion arranged adjacent to the second flow-into side opening portion and a second discharge side opening portion arranged adjacent to the first flow-into side opening portion, the first inlet portion covers the first flow-into side opening portion, the second inlet portion covers the second flow-into side opening portion, and the two inlet portions are respectively provided with two side surface supporting members welded to the shell in an opposite manner and cover members welded to the two side surface supporting members.

Description

technical field [0001] The present invention relates to a welded plate heat exchanger, and more specifically, to a welded plate heat exchanger having a structure for preventing heat damage caused by welding. Background technique [0002] In general, heat exchangers are used to transfer heat from one fluid to another without physical contact. That is, fluids do not mix with each other but only transfer heat, and it is a device used when one type of fluid is to be heated or cooled indirectly. [0003] Among heat exchangers, plate heat exchangers using a plurality of stacked heat transfer plates are widely used because of their excellent heat exchange performance. Plate heat exchangers are generally produced by means of welding, and an example of a welded plate heat exchanger is illustrated in Korean Patent Laid-Open No. 10-0911158. In the welded plate heat exchanger described in the above-mentioned prior art document, members having inflow ports are welded at both ends of th...
