All welds heat interchanger(to hereafter refer to as heat interchanger) is collection row tubular heat exchanger bears the high temperature and high pressure and the detachable disc heat interchanger heat transfer efficiency high merit in a body, has the weight to be light, the heat transfer coefficient is high, resistance small, not easy scaling, compatibility big and so on merits. Moreover, KBQ/KBG/KBY/KBQ-g all welds the disc heat interchanger is one kind of wide flow channel's disc heat interchanger, it is suitable for the temperature difference small current capacity big craft demand, and adapts to has the particle buoy and the viscosity high fluid.
The heat interchanger mainly by the slab, the terminal plate, the turnover oral siphon box and seals is composed prime.
The slab ties by the neighboring two slabs is composed the flow channel by 180 degree junction angles for the arrangement and the involution welding. The fluid flows through the import and export flange by the adverse current form in the flow channel, forms the rapids, thus raised the heat transfer efficiency greatly.
