Description

Technical Field

[0001] This invention relates to the field of refrigeration and air conditioning technology, and in particular to a position adjustment system. Background Technology

[0002] During the installation of water-cooled units, plate heat exchangers need to be fixed to the unit frame through various connection methods. However, due to issues such as manufacturing tolerances and installation accuracy of various components, the installation of plate heat exchangers with non-adjustable installation positions is often difficult, affecting assembly efficiency and the reliability of the assembled structure.

[0003] Currently, during actual installation, the manufacturing and assembly tolerances of various components of plate heat exchangers can be decomposed into three directions in space: up / down, left / right, and front / back. Therefore, plate heat exchangers need to be adjusted in these three directions. However, in current technical solutions, the corresponding connection between the bottom and main mounting plates can only absorb the tolerance in one direction at most, making it difficult to adjust the position of the plate heat exchanger in all three directions. This structure can cause many inconveniences in the installation process when the tolerances of a set of components do not match, such as difficulty in bolt installation or even inability to install, and the base plate not being able to fully support the plate heat exchanger. It may be necessary to select and match components for installation, which seriously affects the efficiency of installation and the reliability of subsequent connections. Summary of the Invention

[0030] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] This invention provides a position adjustment system for adjusting the position of a component to be adjusted on a unit frame. The component to be adjusted in this application is a plate heat exchanger 100. The unit frame includes a side frame 30 and a bottom frame 40. The plate heat exchanger 100 is connected to both the side frame 30 and the bottom frame 40 to achieve installation on the unit frame. In the prior art, when the plate heat exchanger 100 is installed on the unit frame, it is difficult to achieve complete position adjustment in three directions within three-dimensional space. To solve this problem, in the embodiments provided in this application, referring to… Figures 1 to 6 As shown, the position adjustment system includes a first adjustment unit 10, wherein:

[0032] The first adjustment unit 10 includes a first mounting plate 11 and a first adjustment member 12. The first mounting plate 11 is connected to the side wall of the plate heat exchanger 100. The plate heat exchanger 100 is mounted on the side frame 30 via the first mounting plate 11. The first adjustment member 12 is used to adjust the reciprocating movement of the first mounting plate 11 along the first direction D1, the second direction D2, and the third direction D3. The first direction D1, the second direction D2, and the third direction D3 are perpendicular to each other. The first direction D1 is a horizontal direction, the second direction D2 is a horizontal direction perpendicular to the first direction D1, and the third direction D3 is the direction of gravity. Thus, the first adjustment member 12 can adjust the position of the first mounting plate 11 in the horizontal and vertical directions, thereby achieving precise adjustment in three directions when the plate heat exchanger 100 is installed on the side frame 30, improving the installation accuracy of the plate heat exchanger 100 and the side frame 30.

[0033] The position adjustment system of this application can also be used for other components that need to be adjusted in the first direction, the second direction, and the third direction, and is not limited thereto.

[0034] Reference Figure 3 As shown, the first adjusting member 12 includes a first adjusting part 121, a second adjusting part 122 and a third adjusting part 123. The first adjusting part 121 is used to adjust the first mounting plate 11 to reciprocate along the first direction D1, the second adjusting part 122 is used to adjust the first mounting plate 11 to reciprocate along the second direction D2, and the third adjusting part 123 is used to adjust the first mounting plate 11 to reciprocate along the third direction D3.

[0035] In the embodiments provided in this application, the first adjustment part 121 includes a plurality of first mounting holes 1211 and a plurality of mounting posts 1212. The plurality of first mounting holes 1211 are evenly distributed on the first mounting plate 11, and the plurality of mounting posts 1212 are disposed on the side wall where the plate heat exchanger 100 is connected to the first mounting plate 11. The plurality of mounting posts 1212 are evenly distributed on the side wall of the plate heat exchanger 100, and the positions of the plurality of first mounting holes 1211 and the plurality of mounting posts 1212 correspond one-to-one. When the plate heat exchanger 100 is connected to the first mounting plate 11, after the mounting post 1212 passes through the corresponding first mounting hole 1211, the mounting post 1212 is moved in the first mounting hole 1211 along the first direction D1 to a position that meets the installation requirements and then fixed.

[0036] Preferably, the first mounting hole 1211 is an oblong hole extending along the first direction D1, as shown in the figure. Figure 3 as well as Figure 4 As shown, the first direction D1 is the horizontal left-right direction. After multiple mounting columns 1212 pass through the corresponding first mounting holes 1211 at the same time, the mounting columns 1212 are moved within the first mounting holes 1211, thereby realizing the position adjustment of the plate heat exchanger 100 in the first direction D1.

[0037] Furthermore, the second adjustment part 122 includes a plurality of connecting parts 1221 and a plurality of second mounting holes 1222. The second mounting holes 1222 are provided on the side wall of the first mounting plate 11. The plurality of connecting parts 1221 and the plurality of second mounting holes 1222 are provided in a one-to-one correspondence. The connecting part 1221 includes a first connecting hole 12211 and a first fastener 12212. Each first fastener 12212 can fasten the first connecting hole 12211 and the second mounting hole 1222. The first fastener 12212 moves back and forth in the corresponding second mounting hole 1222 along the second direction D2, thereby adjusting the position of the first mounting plate 11 in the horizontal front-back direction, thereby achieving a precise connection between the first mounting plate 11 and the connecting part 1221.

[0038] Preferably, the second mounting hole 1222 is an oblong hole extending along the second direction D2, and the first fastener 12212 includes a fastening bolt and a fastening nut, as shown in the figure. Figure 1 as well as Figure 3 As shown, the second direction D2 is a horizontal front-back direction perpendicular to the first direction D1. After the fastening bolt passes through the first connecting hole 12211 and the second mounting hole 1222 in sequence, it can move back and forth along the second direction D2 within the second mounting hole 1222 to adjust the position of the first mounting plate 11 and the connecting part 1221. After the adjustment is completed, the position of the first mounting plate 11 and the connecting part 1221 is fixed by the cooperation of the fastening nut and the fastening bolt.

[0039] Furthermore, the third adjustment part 123 includes a second connecting hole 1231, a third mounting hole 1232, and a second fastener 1233. The second connecting hole 1231 is located on the side frame 30, and the third mounting hole 1232 is located on the connecting part 1221. The second fastener 1233 can fasten the second connecting hole 1231 and the third mounting hole 1232 together, thereby connecting the connecting part 1221 to the side frame 30, and then connecting the first mounting plate 11 to the side frame 30, ultimately realizing the connection between the plate heat exchanger 100 and the side frame 30. The second fastener 1233 can reciprocate within the third mounting hole 1232 along a third direction D3 to adjust the position of the connecting part 1221 and the side frame 30 in the third direction D3.

[0040] Preferably, continue to refer to Figure 1 as well as Figure 3 As shown, the third mounting hole 1232 is an oblong hole extending along the third direction D3, which is the direction of gravity. The connecting part 1221 is an L-shaped adapter plate, and the second fastener 1233 consists of a fastening bolt and a fastening nut. The first connecting hole 12211 is located on the side of the adapter plate near the first mounting plate 11, and the third mounting hole 1232 is located on the side of the adapter plate near the side frame 30. When connecting the connecting part 1221 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 part 1221 to the side frame 30. During installation, the fastening bolt can move up and down along the third direction D3 within the third mounting hole 1232 to adjust the relative position of the connecting part 1221 and the side frame 30 in the direction of gravity.

[0041] In one feasible implementation, the first mounting hole 1211 extends 6mm in the first direction D1, and the mounting post 1212 can move 6mm in the left and right directions within the first mounting hole 1211, thus absorbing a 6mm tolerance in the left and right directions. When installing the plate heat exchanger 100, adjustment within a 6mm range in the left and right directions is possible. The second mounting hole 1222 extends 6mm in the second direction D2, and the first fastener 12212 can move 6mm in the front and back directions within the second mounting hole 1222, thus absorbing a 6mm tolerance in the front and back directions. During installation, adjustment within a 6mm range in the front and back directions is possible. The third mounting hole 1232 extends 6mm in the third direction D3, and the second fastener 1233 can move 6mm in the vertical direction within the third mounting hole 1232, thus absorbing a 6mm tolerance in the vertical direction. During installation, adjustment within a 6mm range in the vertical direction is possible.

[0042] When installing the plate heat exchanger 100 and the side frame 30, 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 should be adjusted first for pre-installation. Then, the position between the plate heat exchanger 100 and the bottom frame 40 should be adjusted. After all parts have been adjusted, all connecting parts should be tightened to complete the installation of the plate heat exchanger 100.

[0043] After the plate heat exchanger 100 is installed on the side frame 30, it needs to be fixed to the bottom frame 40. To accommodate the fixing of the plate heat exchanger 100 and the side frame 30, the position adjustment system of this application further includes a second adjustment unit 20. The second adjustment unit 20 is used to adjust the position between the plate heat exchanger 100 and the bottom frame 40. (Refer to...) 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 mounted on the second mounting plate 21. By connecting the second mounting plate 21 to the bottom frame 40, the plate heat exchanger 100 is fixed 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 direction of gravity, so that the plate heat exchanger 100 can be installed in a suitable position above the bottom frame 40 according to the installation requirements.

[0044] In the embodiments provided in this application, reference is made to Figure 1 , Figure 2 as well as Figure 6 As shown, the second adjusting member 22 includes multiple members, which together adjust and fix the relative position between the plate heat exchanger 100 and the bottom frame 40. Each second adjusting member 22 includes a support portion 221, a fourth adjusting portion 222, and a fixing portion 223. The support portion 221 supports the second mounting plate 21. Since the plate heat exchanger 100 is mounted on the second mounting plate 21, the support portion 221 can also support the plate heat exchanger 100. The fourth adjusting portion 222 can adjust the position of the support 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 support portion 221, the fixing portion 223 fixes the positions of the second mounting plate 21 and the support portion 221, thus completing the fixation of the plate heat exchanger 100 and the bottom frame 40.

[0045] In one feasible implementation, refer to Figure 6As shown, the support part 221 includes a support nut 2211, and the fourth adjustment part 222 includes a bolt 2221. The support nut 2211 and the bolt 2221 are threaded together, so that the support nut 2211 can move up and down along the third direction D3 on the bolt 2221. The second mounting plate 21 is provided with a fourth mounting hole 211. After the second mounting plate 21 passes through the bolt 2221 through the fourth mounting hole 211, it is supported on the support nut 2211. So when the support nut 2211 moves up and down along the bolt 2221, it can drive the second mounting plate 21 to move up and down synchronously. The fixing part 223 is a fixing nut 2231, which is threadedly engaged with the bolt 2221. After the second mounting plate 21 is in a suitable position, the fixing nut 2231 is installed on the bolt 2221 from the side of the second mounting plate 21 away from the support nut 2211, and rotated until it clamps the second mounting plate 21 together with the support nut 2211, thereby fixing the second mounting plate 21.

[0046] Based on the above embodiments, the working process of the position adjustment system of this application is as follows: First, the side frame 30 is fixed to the unit. After adjusting the third mounting hole 1232 on the connecting part 1221 to the required position, the positions of the third mounting hole 1232 and the second connecting hole 1231 are pre-fixed using the second fastener 1233, completing the pre-installation of 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 connecting hole 1231 are pre-fixed 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 post 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. 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 to the side frame 30.

[0047] Next, 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 2221 is first adjusted. Then, the plate heat exchanger 100 is supported on the support nut 2211 after passing through the fourth mounting hole 211 through the bolt 2221. Then, the fixing nut 2231 is moved along the bolt 2221 to fix the second mounting plate 21 on the support nut 2211, thus completing the fixing of the plate heat exchanger 100 and the bottom frame 40, thereby achieving precise fixing of the plate heat exchanger 100 on the unit frame.

[0048] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
