<P>PROBLEM TO BE SOLVED: To provide a plate type heat exchanger having a low pressure drop property for minimizing damage to heat transfer plates by thermal deformation caused by the temperature of an operating fluid. <P>SOLUTION: The plate type heat exchanger comprises the plurality of heat transfer plates 1 bonded to one another in a state of being laid one on top of another, and operating fluid flow paths formed in spaces therebetween. Each heat transfer plate 1 has a number of protruded and recessed portions 2, 3 repetitively formed on the surface at predetermined spaces in a Chebron or elliptic shape. The heat transfer plates 1 are bonded to one another with their outer peripheries welded to one another. This kind of a plate type heat exchanger has a low pressure drop property because of the reduced fluid resistance of the operating fluid for minimizing damage to the heat transfer plates by the thermal deformation caused by the temperature of the operating fluid. <P>COPYRIGHT: (C)2009,JPO&INPIT |
