Description

Technical field

[0001] The utility model relates to an assembly technology of a heat pump air conditioner, in particular to an air-cooled heat pump frame structure with improved assembly reliability. [Background Technology]

[0002] In the existing technology, the air-cooled heat pump unit is an integrated air-conditioning circulation system composed of a compressor, a heat exchanger, a heat absorber and other devices, using air as the cold (hot) medium as a dual-purpose cold (heat) source. The air-cooled heat pump unit is a small and medium-sized unit. When in use, the internal system combines the cold and heat sources, making it more suitable for users with heating and cooling needs.

[0003] Since air-cooled heat pump units are typically used in large areas, they are often large-scale. To protect the internal components of the heat pump and the air-cooled unit, a frame is typically installed around the unit to facilitate secure installation and overall transport. However, existing air-cooled heat pump frame structures, which combine the condensing and evaporating components, restrict installation locations and are bulky and difficult to use.

[0004] Moreover, the stability, reliability and strength of the existing air-cooled heat pump unit frame depend on the columns of the entire machine frame. Since there is only one dimension fixed between the columns and the base, if it is fixed horizontally, the fasteners bear the longitudinal shear stress of the frame's gravity; if it is fixed longitudinally, the fasteners bear the lateral shear stress of the equipment's inertia during transportation; in order to improve stability, auxiliary brackets such as triangular plates or reinforcing ribs are usually added to the bottom to increase the strength of the columns, and at the same time, the number of overall fasteners is increased to improve the strength of the frame. Although the existing connection method can improve the stability of the equipment, using this assembly method not only increases material and labor costs, but also has hidden dangers. It will cause the inevitable vibration of the equipment during transportation and operation, causing the fasteners of the triangular plate to loosen or even fall off, thereby affecting the installation firmness of the equipment, and in severe cases may cause the equipment to collapse and be damaged. At the same time, insufficient frame strength will increase the use of external fasteners, increase production costs and poor assembly convenience, which is not conducive to improving production efficiency. [Utility Model Content]

[0005] The utility model provides an air-cooled heat pump frame structure with improved assembly reliability. Through multi-dimensional and multi-plane support and fixation, it effectively overcomes the hidden danger of loosening of traditional connecting parts, effectively improves the strength and reliability of the product, and at the same time simplifies the process and reduces the use of fasteners, effectively reducing production costs.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A frame structure for an air-cooled heat pump with improved assembly reliability includes a base frame and four vertical columns respectively installed at the four corners of the base frame:

[0008] Each of the vertical plate columns is an integrated rib plate structure with three sides folded in the vertical direction, and the two rib plates on the outer sides of each vertical plate column are arranged perpendicular to each other;

[0009] The inner walls of the two ribs on the outside of the bottom end of each vertical plate column form a horizontal mounting surface that fits with the side walls at the corner of the base frame and fixes and limits the base frame in the horizontal direction. The two ribs on the outside of the corresponding bottom end of each vertical plate column are folded inward 90 degrees to form a vertical mounting surface that fits with the top surface of the corner of the base frame and plays a fixing and load-bearing role in the vertical direction; the middle supports of the four vertical plate columns are connected to a central rectangular frame that simultaneously fixes the horizontal crossbeams and longitudinal longitudinal beams distributed along the four sides, and the vertical plate column corners corresponding to the four corners of the central rectangular frame are respectively provided with step plates for supporting and fixing the four corners of the central rectangular frame from the bottom side in the vertical direction:

[0010] The tops of the four vertical plate columns are connected with a top rectangular frame which simultaneously fixes and connects the frames distributed along the four sides;

[0011] An I-shaped rib frame is longitudinally provided between the top rectangular frame and the middle rectangular frame, with upper and lower ends respectively overlapped on the beams on both sides for fixed connection in the longitudinal direction.

[0012] Preferably, all the vertical plate columns are fixedly connected to the top rectangular frame, the middle rectangular frame and the base frame by bolts.

[0013] Preferably, all the vertical plate columns are composed of an integrally formed upper half and lower half in the vertical direction, and are designed to have a structure in which the width of the lower half is greater than the width of the upper half according to the required strength and windproof surface requirements.

[0014] Preferably, the two outer rib edges corresponding to the upper and lower halves of all the vertical plate columns are folded inwards to provide flanges for increasing the strength of the vertical plate columns.

[0015] Preferably, two outer ribs at the connection points between the tops of the four vertical plate columns and the four corners of the top rectangular frame are further extended outward to provide connecting surfaces for increasing the butt contact surface.

[0016] The beneficial effects of the utility model are:

[0017] With the four integrated vertical columns at the four corners as the core, the base frame, middle rectangular frame and top rectangular frame are stacked and connected through the vertical columns; the horizontal beams and longitudinal beams of the middle rectangular frame are respectively assembled on the step plates of the vertical columns, and the step plates play the role of limiting and supporting, and are then fixed simultaneously in the horizontal and vertical directions; the remaining structures are installed in this way to complete the entire frame, thereby strengthening the strength and anti-interference ability of the frame, improving the reliability of the equipment, and at the same time reducing the use of auxiliary materials, optimizing the appearance of the equipment, reducing the cost of the unit, and effectively improving production efficiency.

[0018] The vertical columns utilize a three-sided, folded, integrated ribbed plate structure, providing multi-dimensional, multi-planar support and fixation. This effectively overcomes the potential for loosening of traditional connectors and significantly improves the strength and reliability of the frame. Furthermore, the integrated structure of the vertical columns eliminates existing auxiliary materials such as triangles, reducing the number of assembly steps and the use of fasteners, making assembly and processing more convenient.

The use of an integrated structure reduces the use of connectors, thereby reducing the wear of the anti-corrosion coating and further improving the durability of the frame. The inner walls of the two ribs on the outside at the bottom end of each vertical plate column 2 form a horizontal mounting surface 3 that fits with the side wall at the corner of the base frame 1 and fixes and limits the base frame 1 horizontally. The two corresponding ribs on the outside at the bottom end of each vertical plate column 2 are folded inward 90° to form a vertical mounting surface 4 that fits with the top surface at the corner of the base frame 1 and plays a fixing and load-bearing role in the vertical direction; the two-dimensional and multi-plane constraints at the bottom end of the vertical plate column 2 can resist multi-directional vibration interference and adapt to the vibration influence of transportation and operation under complex working conditions.

[0026] Continue as Figures 1 to 5 As shown, the middle parts of the four vertical plate columns 2 are supported and connected with a middle rectangular frame 5 which fixes the horizontal cross beams and the longitudinal longitudinal beams distributed along the four sides at the same time, and the corners of the vertical plate columns 2 corresponding to the four corners of the middle rectangular frame 5 are respectively provided with step plates 6 for supporting and fixing the four corners of the middle rectangular frame 5 from the bottom side in the vertical direction.

[0027] like Figures 2 to 5 As shown, all vertical plate columns 2 are fixedly connected to the top rectangular frame 7, the middle rectangular frame 5, and the base frame 1 via bolts. All vertical plate columns 2 are composed of an integrally formed upper half 20 and lower half 21. Based on the required strength and windproof surface, the width of the lower half 21 is designed to be greater than the width of the upper half 20. The corresponding outer edges of the two ribs on the upper and lower halves 20, 21 of all vertical plate columns 2 are folded inward and provided with flanges 22 to increase the strength of the vertical plate columns 2. The outer two ribs at the junction of the top of the four vertical plate columns 2 and the four corners of the top rectangular frame 7 also extend outward and are provided with connecting surfaces 23 to increase the butt contact surface.

[0028] In this embodiment, Figure 1 As shown, with the four integrated vertical columns 2 at the four corners as the core, the base frame 1, the middle rectangular frame 5 and the top rectangular frame 7 are stacked and connected through the vertical columns 2. Figure 4As shown, the horizontal and vertical beams of the central rectangular frame 5 are respectively assembled on the stepped plates 6 of the vertical columns 2. The stepped plates 6 serve as position limiters and supports, and are then fixed in both the horizontal and vertical directions. The remaining components are assembled in this manner to complete the entire frame, enhancing the frame's strength and anti-interference capabilities, improving equipment reliability, reducing the use of auxiliary materials, optimizing the frame's appearance, reducing unit costs, and improving production efficiency.
