Abstract
A plate type heat exchanger includes a plurality of laminated plates 11 each having a resin-covered gasket 15 mounted in a gasket groove 13 therein surrounding a heat transfer surface 12. The resin-covered gasket includes a core 15a of elastic material whose liquid-contacted side surface is covered with a corrosion-resistant resin cover 15b. In this plate type heat exchanger, the liquid-noncontacted side of the core 15a is integrally formed with a fixing element 16, while the outer peripheral surface of the plate 11 is formed with a recess 14 adapted to fit on the fixing element 16. Thus, the resin-covered gasket 15 can be mounted in the gasket groove 13 without using any adhesive agent.
