[0042] Embodiment 1

[0043] Figures 1 to 9 As shown, this embodiment provides a double-column support and fixing device, which includes a base assembly 1, an inner short column 2, a middle crossbeam assembly 3, and an outer long column 4.

[0044] The base assembly 1 is composed of multiple horizontally arranged fixedly connected crossbeams and a support plate. A first installation position is provided on the base assembly 1, and the first installation position is suitable for installing the lower structure of the heat pump.

[0045] In this embodiment, the base assembly 1 is a rectangular frame structure. There are four inner short columns 2, and the four inner short columns 2 are respectively fixedly installed at the four corners of the base assembly 1. The inner short columns 2 are perpendicular to the base assembly 1. Flanges 9 are provided at both ends of the inner short columns 2, and the flanges 9 extend towards the first installation position. The base assembly 1 and the middle crossbeam assembly 3 are fixedly connected to the flanges 9 by bolting. The base assembly 1 and the flanges 9 are fixed by three bolts, and the three bolts are not collinear to form a triangular bolted fixation; the middle crossbeam assembly 3 and the flanges 9 are fixed by three bolts, and the three bolts are not collinear to form a triangular bolted fixation. In some other embodiments, the base assembly 1 can also be in the shape of a triangle, a pentagon, or other polygons, and inner short columns 2 are installed at each corner of the base assembly 1.

[0046] The middle crossbeam assembly 3 is fixedly installed on the tops of multiple inner short columns 2. A second installation position is provided on the middle crossbeam assembly 3, and the second installation position is used to carry the upper structure of the heat pump. A lower middle column 5 is also fixedly installed between the base assembly 1 and the middle crossbeam assembly 3, and the lower middle column 5 is arranged at the edge of the base assembly 1. The middle crossbeam assembly 3 includes edge crossbeams that are lapped and fixed on the tops of the inner short columns 2 and the lower middle column 5 to enclose a rectangular frame, and middle crossbeams that are lapped and fixed in the middle of the edge crossbeams and are in a cross shape.

[0047] The outer long column 4 is snap-fitted and installed outside the inner short column 2. The height of the outer long column 4 is greater than that of the inner short column 2, and the outer long column 4 extends above the middle cross beam assembly 3. The outer long column 4 includes a bottom support section 6 and a top enclosure section 7. A transition step 8 is provided at the connection between the bottom support section 6 and the top enclosure section 7. The width of the bottom support section 6 is greater than that of the top enclosure section 7. The middle cross beam assembly 3 is abutted against the transition step 8. A reinforcement assembly 12 is installed between the base assembly 1 and the middle cross beam assembly 3 and the bottom support section 6. The reinforcement assembly 12 can be a reinforcement plate or a reinforcement rib, or a combination of a reinforcement plate and reinforcement ribs. In this embodiment, the reinforcement assembly 12 uses a triangular reinforcement plate.

[0048] To improve the tightness and integrity between the outer long column 4 and the inner short column 2, the bottom support section 6 includes a fitting portion and an inward folding portion connected to both sides of the fitting portion. The fitting portion is installed on the side of the inner short column 2 away from the first installation position, and the inward folding portion is wrapped around both sides of the inner short column 2. In order to organize and fix the wiring harness of the heat pump unit, through holes 10 are reserved in the inner short column 2 and the outer long column 4.

[0049] The double-column support and fixing device provided in this embodiment is composed of a base assembly 1, an outer long column 4, an inner short column 2, a lower middle column 5, a triangular reinforcing plate, and a middle crossbeam assembly 3. After the assembly of the base assembly 1 and the materials on the base assembly 1 is completed, the inner short column 2 is fixed to the threaded fixing holes 11 on the base assembly 1 by bolts. Generally, three bolts are selected for fixation; alternatively, the bolts pass through the through holes on the base assembly 1 and then are locked and fixed with nuts. The three bolts for fixing the inner short column 2 are not collinear to form a triangular stable structure. Two of the bolts are fixed to the inner side of the inner short column 2 with the base assembly 1 through the inward flanges 9 on both sides of the inner short column 2, and the other bolt is fixed to the outer side of the inner short column 2 through the outward flange 9 in the middle of the inner short column 2, so the stability is better. The other lower middle columns 5 are also assembled to the base assembly 1 of the unit with bolts to play a role in assisting in supporting the upper part of the unit's weight. The middle crossbeam assembly 3 is placed on the support plane formed by the inner short column 2 and the lower middle column 5. After aligning its hole positions, it is assembled and fixed with bolts. Therefore, the inner short column 2, the lower middle column 5, and the middle crossbeam assembly 3 form a stable fixing frame. After the assembly of the above fixing frame is completed, the upper structure of the heat pump is installed above the middle crossbeam assembly 3. Finally, the outer long column 4 is installed. The outer long column 4 is translated close to the inner short column 2. The transition step 8 in the middle of the outer long column 4 is in contact with the middle crossbeam assembly 3 up and down, and the bottom support section 6 below is moved to an appropriate limiting position with the inner short column 2 to be pre-positioned first. A horizontally arranged limiting strip 13 is installed at the position above the transition step 8 on the outer long column 4. The distance between the limiting strip 13 and the upper side of the transition step 8 matches the thickness of the middle crossbeam assembly 3, so that the limiting strip 13 can cooperate with the transition step 8 to clamp and install the middle crossbeam assembly 3 between the two. The positioning parts extend downward from the bottom of the inner folded parts on both sides of the bottom support section 6 of the outer long column 4. A positioning groove 14 is provided on the base assembly 1. When the outer long column 4 moves close to the inner short column 2, under the action of gravity, the positioning parts sink into the positioning groove 14 to pre-position the outer long column 4.

[0050] An inner flanging 17 is provided at the bottom of the outer long column 4, and an outer flanging 15 is provided at the bottom of the inner short column 2. A relief opening 16 is provided on the inner flanging 17, and the shape of the relief opening 16 is adapted to the shape of the outer flanging 15. When the outer long column 4 moves close to the inner short column 2, the outer flanging 15 is inserted into the relief opening 16 on the inner flanging 17 to achieve the fitting and positioning of the inner flanging 17 and the outer flanging 15. After the outer long column 4 moves to the preset limit position of the inner short column 2, the bottom of the inner folding parts on both sides of the outer long column 4 is strongly connected to the base assembly 1 and the middle part is strongly connected to the middle crossbeam assembly 3 through triangular reinforcing plates to ensure the stability of the bottom frame structure. Two rows of through holes 10 are opened on the inner folding edge 9 of the inner short column 2 for the routing of the strong wires and weak wires of the unit. The wire harness can be bundled with materials such as cable ties. When it is necessary to remove the outer long column 4 for maintenance or after-sales repair, only the triangular reinforcing plates need to be removed, which greatly enriches the reliability and flexible operation degree of the unit.

[0051] The double-column support and fixing device provided in this embodiment strengthens the load-bearing capacity of the lower part of the unit and improves the overall stability of the unit through the double-column assembly scheme of the inner short column 2 and the outer long column 4. It changes the assembly process of the traditional single column, enabling the outer long column 4 to be assembled after the fin heat exchanger is assembled, reducing the possibility of the fin heat exchanger being scratched by the column to almost zero, and significantly improving the quality reliability of the fin heat exchanger and the product. By using the flanging 9 to bolt-connect with the base assembly 1 and the middle crossbeam assembly 3 to fix the inner short column 2, all the connection and fixing bolts of the double-column support and fixing device are inside the frame, and the connection and fixing method of the column cannot be seen from the appearance of the unit, greatly improving the appearance of the product and ensuring a clean and tough appearance; moreover, the design of hiding the bolts inside greatly reduces the phenomenon of unsightly appearance caused by the protrusion and rust of the bolts.

[0052] Embodiment 2

[0053] This embodiment provides a heat pump unit with the double-column support and fixing device described in Embodiment 1. The lower structure of the heat pump is fixedly installed on the base assembly 1, and the upper structure of the heat pump is fixedly installed on the middle crossbeam assembly 3. By using the double-column support and fixing device in Embodiment 1 to install the upper and lower structures of the heat pump unit. After installing the structures such as the water receiving tray, fin heat exchanger, and crossbeam on the upper structure of the heat pump, the outer long column 4 can be assembled. The bottom of the outer long column 4 is snap-fitted with the base assembly 1, the middle is snap-fitted with the middle crossbeam assembly 3, and the vertical direction is snap-fitted with the inner short column 2. By installing the upper structure first and then the outer long column 4, the possibility of the fin heat exchanger body being scratched by the column during the installation of the fin heat exchanger is reduced, and the quality reliability of the fin heat exchanger and the product is improved.

[0054] Obviously, the above embodiments are merely examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
