Claims

[Scope of utility model registration request]

Horizontal flat heat transfer bodies 11 to 13 arranged in parallel
Each of the heat transfer bodies 11 to 13 is composed of a dish-shaped heat transfer plate 21 to 23 with upper and lower flanges 31, and a flange 31 extending in the front and back direction is provided at the center of the bottom wall 32 of the heat transfer plate 23. A U-shaped cross-sectional bulge 33 for forming an air supply passage is provided with the same height as that of the bulge. Communication holes 36 and 37 are provided in the side wall 33a of the bulging portion 33 so as to pass through the bulging portion 33 in the left-right direction, and a recess 38 for forming a cooling water passage extending in the front-rear direction is provided in the center of the tip wall 33b of the bulging portion 33. is provided, the recess 38 is formed deeper at both front and rear ends than the front and rear intermediate parts, and both front and rear ends of the recess bottom wall 38a are at the same level as the heat exchanger plate bottom wall 32 outside the bulge 33, Cooling water holes 41 and 42 are provided at both front and rear ends of the bottom wall 38a of the recess.
Of the two upper and lower heat transfer plates 21 to 23 constituting one heat transfer body 11 to 13, the upper heat transfer plates 21 to 23 face downward, and the lower heat transfer plates 21 to 23 face downward. 23 Both heat exchanger plates 2 are arranged facing upward.
3 are two adjacent heat transfer bodies 1 which are joined with their openings facing each other and are overlapped and joined at each flange 31 and bulging part tip wall 33b.
Four heat transfer plates 21 to 23, two each on the top and bottom of 1 to 13
Among these, the upward heat transfer plates 21 to 23 on the lower side of the upper heat transfer bodies 11 to 13 and the downward heat transfer plates 21 to 23 on the upper side of the lower heat transfer bodies 11 to 13 are connected to the air supply holes 34.
, 35 and the cooling water holes 41, 42 are arranged so that the upper and lower ones match each other, and the respective bottom walls 3
The water-cooled intercooler is overlapped and joined at 2.
