<p>The heat exchanger with a fan below it has a housing fastened to a wall at the rear. The exchanger has two shells surrounding the matrix, the matrix being inclined. Each shell has two side walls with edges where the matrix is held, with a rubber seal interposed. The seal has an H-section, the grooves fitting over the edges. One shell forms the rear wall. The other has two front walls forming an L pointing outwards, the angle between the walls being almost a right angle. The lower wall dips down slightly from the horizontal, the upper wall bends inwards slightly from the vertical.</p> |
