PURPOSE:To improve the heat transfer performance by disposing a deviating flow prevention plate having multiple holes which are spaced wider near inlet pipes for a low-pressure and a high-pressure fluid and increasingly narrower as they become distant between a laminating body and a header so that the whole area of the heat transfer surface of a heat transfer plate may be utilized. CONSTITUTION:A low-pressure fluid entering from a low-pressure fluid inlet pipe 9 to the central part of a header 5 is distributed properly in accordance with the spacing of holes 15 in a deviating flow prevention plate 13 to be dispersed over the entire surface of a heat conducting plate 1 and passes through a low-pressure fluid passage 7, during which process it exchanges the heat with a high-pressure fluid entering from a high-pressure fluid inlet 10 to the peripheral area of a header 6 to pass through a high-pressure fluid passage 8, and it is released thereafter from a low-pressure fluid outlet 11 in the center of the header 6. The high-pressure fluid entering from the inlet pipe 10 is distributed in accordance with the spacing of holes 16 in a deviating flow prevention plate 14 to be dispersed over the entire surface of the heat conducting plate 1 to pass through the passage 8, during which process it exchanges the heat with the low-pressure fluid to be released thereafter from a high-pressure fluid outlet 12. In this manner, the length of the superposing body does not matter, and the entire surface of the heat conducting surface of the heat transfer plate can effectively be utilized so as to improve the heat transfer performance. |
