[0033] In summary, when the heat exchanger assembly positioning tool is used,

[0034] The base 1 is rotatably connected to the bottom wall of the stud 4 at the center frame 2. The stud 4 rotates to drive the concave portion of the lower end of the center frame 2, so that the lower end of the center frame 2 moves up and pushes the top of the top seat 17, which is used to change the height of the top seat 17 to adapt to different assembly environments. For example, different workers have different heights, and the height of the top seat 17 is adjusted to a position suitable for the height of the workers, which is more flexible when used. The left and right end walls of the concave portion of the center frame 2 are both provided with movable limit columns, and the bottom of the limit column is fixedly connected to the base 1, so that the concave portion of the lower end of the center frame 2 is more stable when it is displaced;

[0036] The threaded rods 23 at the left and right end walls of the top seat 17 rotate to drive and adjust the height of the support plates 24, so that the height of the two support plates 24 at the top of the top seat 17 is controllable and adjustable, and is similar to the height of the top support plate 7. Then, the inner screw 6 at the top support plate 7 is rotated to adjust the height of the top support plate 7, so as to expose the bottom area of ​​the placed heat exchanger, and then, it is convenient to perform assembly and control from the bottom of the heat exchanger assembly accessories, such as tightening the screw connectors, etc.;

[0037] The plate recess 25 of the support plate 24 is used to carry the end angle of the heat exchanger accessories, tighten the side fixing rod 26 and the side fixing rod 27, and lock and limit the heat exchanger accessories, such as positioning the heat exchanger base, and then facilitate the assembly operations such as plugging in other accessories of the heat exchanger, such as pipes and fins;

[0038] In the top opening 20 at the top seat 17, a top plate 21 is placed, which can be pulled out and displaced, and has higher flexibility when used. At the same time, after the top plate 21 is pulled out and moved, the top opening 20 is exposed. At this time, the more protruding part of the bottom of the heat exchanger accessories can be extended into the top opening 20, which does not affect the assembly of the heat exchanger accessories after placement. At the same time, the wear strip 22 at the top plate 21 is used to increase the stability of the top plate 21 when it moves in the top opening 20. After the top plate 21 is pulled out, the upper end of the top plate 21 will not be blocked by the placed heat exchanger, and the upper end area is sufficient.
