1. a heat-exchangers of the plate type, this heat-exchangers of the plate type lamination plurality of plates and being formed, is characterized in that,Be provided with in each plate of above-mentioned plurality of plates:

  • Gain the first rank in the either end side of length direction the first inlet hole of entrance of body,The first outflow hole of the outlet of above-mentioned first fluid is become in the end side of the length direction contrary with above-mentioned first inlet hole,The second inlet hole of the entrance of second fluid is become in the either end side of length direction, andThe second outflow hole of the outlet of above-mentioned second fluid is become in the end side of the length direction contrary with above-mentioned second inlet hole;

    Above-mentioned each plate is between the plate of adjacent lamination, form the above-mentioned first fluid making to flow into from above-mentioned first inlet hole flows to first flow path from above-mentioned first outflow hole to width diffusion and the stream that the above-mentioned second fluid flowed into from above-mentioned second inlet hole is flowed to the second stream of above-mentioned second outflow hole to above-mentioned width diffusion, the above-mentioned first fluid flowing through above-mentioned first flow path is made to carry out heat exchange with the above-mentioned second fluid flowing through above-mentioned second streamThe length of the above-mentioned length direction of above-mentioned each plate is the length of more than 4 times of the length of above-mentioned width;

    From above-mentioned first inlet hole to the length of the plate end of the above-mentioned width of that side close to above-mentioned first inlet hole, from above-mentioned first outflow hole to the length of the plate end of the above-mentioned width of that side close to above-mentioned first outflow hole, from above-mentioned second inlet hole to the length of the plate end of the above-mentioned width of that side close to above-mentioned second inlet hole with from above-mentioned second outflow hole to the length of the plate end of the above-mentioned width of that side close to above-mentioned second outflow hole, be all the length of below 5.6mm;

    The aperture area of above-mentioned first inlet hole and the aperture area of above-mentioned first outflow hole are all little than any one in the aperture area of above-mentioned second inlet hole and the aperture area of above-mentioned second outflow hole;

    In above-mentioned each plate, arrange multiple recess and protuberance at above-mentioned length direction, this recess and protuberance have both ends in the both end sides of above-mentioned width, by turning back a little and be formed as V-shaped having from above-mentioned both ends along the position that above-mentioned length direction staggers;

    For recess and the protuberance of above-mentioned V-shaped, near the central portion of above-mentioned length direction, above-mentioned turning back a little is formed in the center of above-mentioned width, near at least any one first hole in above-mentioned first inlet hole and above-mentioned first outflow hole, more close to above-mentioned first hole then above-mentioned turn back a little more from the off-centring of above-mentioned width near above-mentioned first hole.
