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...
