Description

The invention relates to the field of ventilation and air conditioning and can be used in devices for heat recovery. The purpose of the invention is to increase the heat exchange surface. Figure 1 shows the heat exchange surface in the process of stretching the bag, end view; 2, the arrangement of all the elements before connecting the heat exchange surface to parts of the heat exchanger body arrows indicates the directions of the forces; figure 3 heat exchanger with a heat transfer surface, manufactured by the proposed method; figure 4 -. section aa on fig.Z; in FIG. 5, node I in FIG. 4; figure 6 - section bb in figure 3; figure 7 - section bb in fig.Z. A heat exchanger with a heat transfer surface comprises a housing 1 of air distributors with devices 2 and 3 and a package of sheets 4 of polymer film. Air distribution devices 2 and 3 have alternating ducts 5 and 6 for intake and exhaust air, pipes 7 and 8 for inlet and outlet of intake air, and pipes 9 and 10 for inlet and outlet for exhaust air. The sheets 4 packages are connected in pairs between a set of longitudinal seams 11 with the Formation of channels 12 and 13 alternating in staggered order for supply and exhaust air. Sheets 4 of each subsequent layer of the film are displaced by half of the seam 1I at the joint between each other, and the seam is made zigzag. The diagonal rows of channels 12 and 13 are parallel to side panels of housing 1 and between the corresponding channels 5 and 6 of air distribution devices 2 and 3. Heat transfer surfaces are attached to air distribution devices 2 and 3 by means of strips 4 fixed at the ends of each sheet 4 n to be installed along each dI; Agonal rows of channels 12 and 13. The slats 14 are connected to the wall 15 of the channels 5 and 6 of the air-distributing devices 2 and 3. To install the slats 14 inside the stack of sheets 4, the seams I1 are made not reaching the ends of the sheets 4 of the pack and to the slats 14. The heat exchanger contains also a drip pan 16 for collecting condensate and a choke 17 for removing it. The manufacture of the heat transfer surface of the heat exchanger is carried out as follows. Polymeric film sheets 4 are interconnected by longitudinal seams 11 to form channels 12 and 13 alternating in staggered order for supply and exhaust air, stretched and connected to air distribution devices 2 and 3 and to Body 1, Sheets 4 of each subsequent When joined together, the film layer is displaced halfway through the I1 seam, the seam 11 is zigzagged, then the rods 18 are inserted into the gaps between the seams 11 of the upper and lower layers and the upper and lower rows of rods 18 are stretched in opposite directions X The rods 18 are also inserted into the outer side channels formed and the ends of all the rods 18 are attached to the housing 1. The wire transfer surfaces are attached to the air distribution devices 2 and 3 using the rods 14 attached to the ends of each sheet 4.

1. A METHOD FOR PRODUCING A HEAT TRANSFER SURFACE OF A HEAT EXCHANGER, which consists in connecting sheets from a polymer film with longitudinal seams with the formation of channels alternating in a checkerboard pattern for supply and exhaust air, stretching and connecting to an air distribution and distribution box that, in order to increase the heat-exchange surface, the sheets of each subsequent film layer, when connected, are displaced by a half-, well, a seam, and the seam is made in a zigzag pattern, then at the intervals between the seams rods are introduced into it and the lower layers and the upper and lower rows of rods are stretched in opposite directions, rods are also introduced into the formed extreme lateral channels and the ends of all rods are attached to the body. 2. The method of pop. 1, characterized in that the heat transfer surfaces are connected to the air distribution devices with the help of strips, which are at the ends of each sheet are shrunk.
