DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Refer to the attached Figure 1-5 A lightweight plate heat exchanger, comprising a front end plate 1 and a rear end plate 2 for mounting a heat exchange plate 3, wherein the front end plate 1 and the rear end plate 2 are both made of aluminum alloy, and a weight reduction groove 4 is provided in the middle of each of the front end plate 1 and the rear end plate 2, a counterweight plate 5 is installed in the weight reduction groove 4, and a cavity 6 is provided in each of the front end plate 1 and the rear end plate 2;

[0019] By making the front end plate 1 and the rear end plate 2 of aluminum alloy material, the weight of the equipment can be reduced while ensuring strength and corrosion resistance, and the setting of the weight-reducing groove 4 in the middle makes the weight of the end plate lighter, which can reduce the weight when transporting the heat exchanger. The subsequent addition of the weight plate 5 will not affect the normal use of the heat exchanger, and the problem of unstable installation will not occur due to the weight reduction. The middle of the front end plate 1 and the rear end plate 2 is a cavity 6, which further reduces the weight and realizes the lightweight design of the heat exchanger.

[0020] Specifically, the opposite surfaces of the front end plate 1 and the rear end plate 2 are glued with a first sealing gasket 16, and one side of the counterweight plate 5 is glued with a second sealing gasket 17. The first sealing gasket 16 includes a sealing gasket extension 18 that is bonded to the second sealing gasket 17. The outer ring of the second sealing gasket 17 and the sealing gasket extension 18 are both provided with rubber teeth 19 that fit together.

[0021] Such a setting ensures the sealing of the counterweight plate 5 during the later installation. Specifically, after the counterweight plate 5 is installed in the weight reduction groove 4, the rubber teeth 19 on the outer ring of the second sealing gasket 17 will engage with the rubber teeth 19 on the sealing gasket extension 18, so that the combination is tighter, and glue will be applied to the two sealing gasket extensions 18 during installation.

[0022] It should be noted that, in this embodiment, multiple threaded holes 8 are provided on both sides of the front end plate 1 and the rear end plate 2, as well as in the middle of the counterweight plate 5, and a first bolt 9 is threadedly installed between the threaded holes 8 on both sides, and a first nut 10 is threadedly installed on the first bolt 9, and a plurality of second bolts 13 for supporting and fixing the heat exchange plate 3 are installed between the front end plate 1 and the rear end plate 2, and multiple threaded holes 8 are provided on both sides of the front end plate 1 and the rear end plate 2, the second bolt 13 passes through the third nut 300 and is threadedly installed between the two threaded holes 8 on the same side, and a second nut 14 is threadedly installed on the second bolt 13, and threaded holes 8 are provided on the upper and lower sides of the front end plate 1 and the rear end plate 2, and a guide rod 200 is threadedly installed between the two threaded holes 8, and a third nut 300 is threadedly installed on the guide rod 200.

[0023] It should also be noted that, in this embodiment, two medium inlets and outlets 15 are provided on both sides of the front end plate 1, and the four medium inlets and outlets 15 are respectively provided on both sides of the weight reduction groove 4. A plurality of steel structure support blocks 7 and a steel structure stabilizing plate 11 are fixedly installed in the cavity 6, and the threaded holes 8 are all provided on the steel structure stabilizing plate 11 through the front end plate 1 or the rear end plate 2.

[0024] During the specific installation, after the heat exchange plate 3 is installed on the front end plate 1 and the rear end plate 2, it is first installed by the second bolt 13 and the guide rod 200, and then the second bolt 13 is threadedly installed between the two threaded holes 8 at its installation location, and then the second nut 14 is threadedly installed to fix it. Then the guide rod 200 is clamped on the heat exchange plate 3, and then it is threadedly installed between the two threaded holes 8 at its installation location, and then the third nut 300 is threadedly installed to fix it. Finally, the counterweight plate 5 is clamped into the weight reduction groove 4, and then the counterweight plate 5 is installed, and the first bolt 9 is threadedly installed into the threaded hole 8 at the installation location, and finally the first nut 10 is threadedly installed to fix it. In this way, the frame structure installation similar to the traditional plate heat exchanger in this scheme is completed.

[0025] It should be noted that this type of installation method is a common frame installation method for plate heat exchangers known to those skilled in the art. The specific installation method described in this solution is to point out that the cavity 6 is provided inside the front plate 1 and the rear plate 2. While reducing the weight, the installation stability will be reduced. Therefore, in this solution, multiple steel structure stabilizing plates 11 are welded at the installation location so that the threaded holes 8 are opened on the steel structure stabilizing plates 11, so that the stability will not be reduced.

[0026] It should also be noted that the specific working principle of the plate heat exchanger in this scheme is no different from that of the existing exchanger, and is well known to the staff in this technical field. Moreover, because this scheme improves the front and rear end plates of the existing plate heat exchanger to meet the requirements of lightweight design, the specific working principle of the plate heat exchanger will not be described in detail.
