<P>PROBLEM TO BE SOLVED: To improve heat exchanging performance by increasing dimple density in a header plateless heat exchanger in which an element is constituted of a pair of grooved plates, and provided with dimples on its inner and outer faces. <P>SOLUTION: The element 7 is formed of the first plate 3 and the second plate 4, a bottom surface 1 of the first plate 3 is provided with a number of dimples 10 protruding to its inner face side, and the second plate 4 is provided with the dimples 10 protruding to an outer face side. Positions of the dimples 10 of the first plate 3 and the second plate 4 do not agree with each other so that they are not overlapped to each other on a plane. <P>COPYRIGHT: (C)2013,JPO&INPIT |
