The second fastener 1233 can reciprocate in the third mounting hole 1232 along the third direction D3 to adjust the position of the connection portion 1221 and the side frame 30 in the third direction D3.

[0026] Preferably, continue to refer to Figure 1 as well as Figure 3 As shown, the third mounting hole 1232 is a waist-shaped hole extending along the third direction D3, the third direction D3 is the gravity direction, the connecting portion 1221 is an L-shaped adapter plate, the second fastener 1233 is a fastening bolt and a fastening nut, the first connecting hole 12211 is provided on the side of the adapter plate close to the first mounting plate 11, and the third mounting hole 1232 is provided on the side of the adapter plate close to the side frame 30. When the connecting portion 1221 is connected to the side frame 30, the fastening bolt is passed through the third mounting hole 1232 and the second connecting hole 1231 in sequence, and then the fastening nut is tightened to fix the connecting portion 1221 to the side frame 30. During the installation process, the fastening bolt can move up and down in the third mounting hole 1232 along the third direction D3 to adjust the relative position of the connecting portion 1221 and the side frame 30 in the gravity direction.

[0027] In a feasible embodiment, the length of the first mounting hole 1211 extending in the first direction D1 is 6 mm, and the mounting column 1212 can move 6 mm in the left-right direction in the first mounting hole 1211, that is, it can absorb the 6 mm tolerance in the left-right direction. When installing the plate heat exchanger 100, it can be adjusted within a range of 6 mm in the left-right direction. The length of the second mounting hole 1222 extending in the second direction D2 is 6 mm, and the first fastener 12212 can move 6 mm in the front-back direction in the second mounting hole 1222, that is, it can absorb the 6 mm tolerance in the front-back direction.

The length of the third mounting hole 1232 extending in the third direction D3 is 6 mm, and the second fastener 1233 can move 6 mm in the up-down direction in the third mounting hole 1232, that is, it can absorb the 6 mm tolerance in the up-down direction. When installing, it can be adjusted within a range of 6 mm in the up-down direction.

[0028] When installing the plate heat exchanger 100 and the side frame 30, it is necessary to first adjust the positions of the plate heat exchanger 100 and the side frame 30 in the first direction D1, the second direction D2 and the third direction D3, and then perform pre-installation, and then adjust the position between the plate heat exchanger 100 and the bottom frame 40. After all parts are adjusted, tighten all connecting parts to complete the installation of the plate heat exchanger 100.

[0029] After the plate heat exchanger 100 and the side frame 30 are installed, the plate heat exchanger 100 needs to be fixed on the bottom frame 40. In order to adapt to the fixation of the plate heat exchanger 100 and the side frame 30, the position adjustment system of the present application also includes a second adjustment unit 20, which is used to adjust the position between the plate heat exchanger 100 and the bottom frame 40. Figure 1 As shown, the second adjustment unit 20 includes a second mounting plate 21 and a second adjustment member 22. The plate heat exchanger 100 is arranged on the second mounting plate 21. The second mounting plate 21 is connected to the bottom frame 40 to fix the plate heat exchanger 100 to the bottom frame 40. The second adjustment member 22 is used to adjust the second mounting plate 21 to reciprocate along the third direction D3, that is, the second adjustment member 22 can adjust the second mounting plate 21 to reciprocate along the gravity direction, and then the plate heat exchanger 100 can be installed at a suitable position above the bottom frame 40 according to installation requirements.

The second adjusting member 22 includes a supporting portion 221, a fourth adjusting portion 222 and a fixing portion 223. The supporting portion 221 is used to support the second mounting plate 21. Since the plate heat exchanger 100 is arranged on the second mounting plate 21, the supporting portion 221 can be used to support the plate heat exchanger 100. The fourth adjusting portion 222 can adjust the position of the supporting portion 221 in the third direction D3, that is, adjust the distance between the plate heat exchanger 100 and the bottom frame 40. After the fourth adjusting portion 222 completes the adjustment of the position of the supporting portion 221, the second mounting plate 21 and the supporting portion 221 are fixed by the fixing portion 223, and the fixing of the plate heat exchanger 100 and the bottom frame 40 can be completed.

[0031] In a feasible implementation mode, referring to Figure 6As shown, the support portion 221 includes a support nut 2211, and the fourth adjustment portion 222 includes a bolt member 2221. The support nut 2211 is threadedly matched with the bolt member 2221, so that the support nut 2211 can move up and down along the third direction D3 on the bolt member 2221. A fourth mounting hole 211 is provided on the second mounting plate 21. After the second mounting plate 21 passes through the bolt member 2221 through the fourth mounting hole 211, it is supported on the support nut 2211, and when the support nut 2211 moves up and down along the bolt member 2221, it can drive the second mounting plate 21 to move up and down synchronously. The fixing portion 223 is a fixing nut 2231, which is threadably matched with the bolt member 2221. After the second mounting plate 21 is located at a suitable position, the fixing nut 2231 is installed on the bolt member 2221 from the side of the second mounting plate 21 away from the supporting nut 2211, and is rotated until it clamps the second mounting plate 21 together with the supporting nut 2211, thereby fixing the second mounting plate 21.

[0032] Based on the above embodiments, the working process of the position adjustment system of the present application is as follows: first, the side frame 30 is fixed to the unit, and after the third mounting hole 1232 on the connecting portion 1221 is adjusted to the required position, the positions of the third mounting hole 1232 and the second connecting hole 1231 are pre-fixed by using the second fastener 1233 to complete the pre-installation in the third direction D3; then, the second mounting hole 1222 on the first mounting plate 11 is adjusted to the required position, and the second mounting hole 1222 and the second connecting hole 1231 are pre-fixed by using the first fastener 12212 The position of the first connecting hole 12211 is pre-fixed to complete the pre-installation in the second direction D2; then, the mounting column 1212 on the plate heat exchanger 100 is inserted into the first mounting hole 1211, and the position of the plate heat exchanger 100 in the first direction D1 is adjusted. After the adjustment is completed, the plate heat exchanger 100 is fixedly connected to the first mounting plate 11, and finally, the pre-fixed position is completely fixed by the first fastener 12212 and the second fastener 1233, thereby completing the fixation of the plate heat exchanger 100 and the side frame 30.

[0033] Then, the plate heat exchanger 100 is fixed to the second mounting plate 21. According to the height requirement between the plate heat exchanger 100 and the bottom frame 40, the position of the support nut 2211 on the bolt member 2221 is first adjusted. Then, the bolt member 2221 is passed through the fourth mounting hole 211 to support the plate heat exchanger 100 on the support nut 2211. Then, the fixing nut 2231 is moved along the bolt member 2221 to fix the second mounting plate 21 on the support nut 2211, thereby completing the fixation of the plate heat exchanger 100 and the bottom frame 40, thereby achieving the precise fixation of the plate heat exchanger 100 on the unit frame.

The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings.
