Description

The invention relates to a type of heat exchangers made up of slit-shaped plate elements to form a cavity for the passage of heat transfer medium when the set of elements is tightened with through-bolts and from ribs with flanges on the edges that form solid side walls of the device during assembly.

In the proposed heat exchanging device, the plate-ribs, provided with cutouts corresponding to the living section of the heat carrier passageway and openings for the clamping bolts, alternate with the laying elements during assembly.

In FIG. 1 is a front view of a plate-fin of a heat exchanger; FIG. 2 is a front view of a gasket element; FIG. 3 is a sectional view taken along line 3-5 in FIG. 2, FIG. 4 is a section through the plate along line 4-4 in FIG. one; FIG. 5 is a side view with a partial section of a heat exchanger.

The heat exchange device consists of plate ribs 10 and gasket elements and that are folded together.

their flat sides, with one spacer being placed between each two plates.

The ribs 10 may be made of any suitable material, but they are preferably stamped from copper sheet or other material having a high thermal conductivity. The plates 10 are preferably made rectangular in shape and are provided with central notches 12. The parts 13 of the plate adjacent to the middle part of the notch 12 are protruding inwards, so that the notch 12 has relatively wide end parts and a narrow middle part. Each plate 10 has holes 14 for fastening bolts located on the sides of the narrow part of the notch 12. Plate 10 also has bolt holes 15 located at its upper and lower edges.

Each plate 10 has a rectangular flange 16 along the side edge projecting laterally to one side of the plate. Each flange 16, in turn, ends with a flange 17 protruding inward and located parallel to the plate at some distance from it. The spacers 11 are comparatively thicker than the plates 10 and are positioned between the plates to keep them parallel to each other and at some distance.

Each gasket element / 7 has a notch 18, corresponding in shape and size to a notch 12 in the plate 10. The anchoring elements 11 are provided on the sides with recesses 19 that form the notches 20 for the bolts. The plates 10 and the gasket elements 7 / are assembled together with their flat sides so that the notches 18 in the gaskets coincide with the notches 12 in the plates 10. Thus, an appropriate number of plates and gaskets are assembled to obtain a heat exchanger with the desired radiating surface. The thick end plates 21 are placed at the ends of the assembled kit, and all together are fastened with bolts 22 passing through the openings 15. The bolts are clamped with nuts 23 or other suitable means.

Although it would normally be sufficient to have only two bolts 22 to hold the plates and gaskets in the proper position, it is preferable to have two more bolts passing through the holes 14 in the plates and entering the gasket slots 20; In both cases, the bolts are fastened with nuts 25. The heatsink assembled in this way is preferably tested with hydraulic pressure, and the nuts 23 are tightened with sufficient force to obtain a waterproof and gas-tight connection between the plates and the gaskets.

Since the flanges 16 correspond in width to the thickness of the gaskets 11,

then each flange 17 presses against the next plate, which results in a radiator with closed sides. Cuts 12 and 18 form a radiator chamber with smooth walls. The end plates-plates 21 have holes with corresponding screw thread for screwing water or steam pipes, which serve to pass the heat transfer fluid through the radiator chamber. Since each plate 10 forms part of the walls of the chamber, it will be in direct contact with the coolant, as a result of which heat or cold can be effectively transferred from the coolant to parts of the radiator plates protruding beyond the edges of the gaskets //.

The cutouts 12 and 18 can be modified to give the camera any shape, according to the living section of the passage for the coolant. Similarly, bolt holes may be positioned in any suitable manner.

The subject is invented and.

The heat exchanger is made of lamellar elements with slots that form a cavity for the passage of heat transfer medium when the set of elements is tightened with through bolts and from plate ribs with flanges on the edges that form during installation the flat side walls of the device, characterized in that the plate ribs 10 with cutouts corresponding to the living section of the passage for the heat transfer fluid, and with openings for fastening bolts, are arranged in alternating order with the spacer elements 11.
