METHOD FOR BRAZING WELDING A FIXING PLATE AND A FLOW CAP IN HEAT EXCHANGER AND THE HEAT EXCHANGER USING THEREOF

摘要

PURPOSE: them are arranged in front of the soldering that removal needs processing path nut cap spot welding fixed plate and heat exchanger in a kind of soldering, fixed plate and the heat exchanger of path cap and corresponding heat exchanger. ;CONSTITUTION: heat exchanger includes multiple heat exchanger tubes, fixed plate (10), path cap (20). Fixed plate is inserted at each heat exchanger tube both ends. The path cap is Welding to fixed plate and closes the both ends of heat exchanger tube to form flow path. Multiple elastic protrusions (11), which snap attached to, is formed in fixed plate, one end cap of path forms the shape of " thin " and has manufactured plastered and fixed plate and is connected by a snap to elastic protrusion, other end path cap includes stepped part (21), a part lid of other end flow path includes ladder-like part, and the end contact resilient protrusion and pedestal (21a) stepped portion of step-portion (21b) are obturaged and fixed plate. ;The 2011 of copyright KIPO submissions
