Description

Technical Field

[0001] The utility model relates to the field of refrigeration units, in particular to a drainage trough with an inverted M-shaped coil structure. Background Art

[0002] Many air-cooled central air conditioning units are equipped with drain gutters to collect condensate from the coils. However, during design, it was found that as cooling capacity increases, the coil length and drain gutter fabrication become increasingly difficult. Furthermore, once the gutter is secured at the bottom, water leakage can occur, which can negatively impact the lifespan of the unit's electrical components and sheet metal. Therefore, there is an urgent need to improve the inverted M-shaped coil drain gutter structure to optimize its fabrication, fixing, and installation location. Utility Model Content

[0003] This utility model aims to overcome the shortcomings of the existing technology by providing a drainage trough with an inverted M-shaped coil structure. This design leverages the slope of the inverted M-shaped coil to facilitate condensate collection. Furthermore, the welded metal panels on both sides simplify the trough's fabrication. Side rivet nuts secure the trough, preventing bottom leakage. The welded bottom drain pipe eliminates the risk of water impacting the unit's electrical components and sheet metal. The trough is easy to fabricate and has a reasonable structure.

[0004] The purpose of the utility model is to achieve the following technical solutions: the drainage trough of the inverted M-shaped coil structure comprises:

[0005] The coil base includes a flat surface portion parallel to the horizontal plane and an inclined surface portion connected to one side of the flat surface portion. There are two sets of coil bases, which are symmetrically arranged so that the inclined surfaces of the two sets face each other.

[0006] The coil assembly includes a coil body and coil end plates disposed at both ends of the coil body. There are four sets of coil assemblies, two of which are close to each other and fixed to the inclined portions of the two sets of coil bases, and the other two sets of coil assemblies are fixed to the flat portions of the two sets of coil bases. The four sets of coil assemblies form an inverted "M"-shaped structure; and

[0007] The drainage trough is fixedly connected to the bottom of the inclined portion of each coil base and is used to collect condensed water that falls along the inclined portion of the coil assembly.

[0008] As a further technical solution, the side of the planar portion away from the inclined portion is connected to a first support portion with an "L"-shaped cross section for support, and the side of the inclined portion away from the planar portion is connected to a second support portion with an "L"-shaped cross section for support.

[0009] As a further technical solution, a number of rivet nut holes are evenly opened along the surface of the second support part, and rivet nut holes are also correspondingly opened on the outer edge of the drainage groove, so that the second support part and the drainage groove are fixed by rivet nuts.

[0010] As a further technical solution, a plurality of coil fixing holes are provided at both ends of the planar portion and the inclined portion, and corresponding coil fixing holes are also provided on the coil end plate, so that the coil assembly is fixed to the planar portion and the inclined portion through the coil end plate.

[0011] As a further technical solution, a coil reinforcement plate is installed at the middle position of the coil assembly.

[0012] As a further technical solution, drainage trough side sealing plates are welded and fixed to both ends of the drainage trough.

[0013] As a further technical solution, a drainage hole is provided at the bottom of the drainage trough for installing a drainage pipe to drain the collected condensed water out of the unit.

[0014] The beneficial effects of the utility model are:

[0015] 1. The coil base is provided with an inclined portion. After the coil base and coil assembly are fully fixed, an M-shaped coil structure is formed.

DETAILED DESCRIPTION

[0027] The following is a detailed introduction to the present invention with reference to the accompanying drawings:

[0028] Example: As shown in the attached Figures 1 to 7 As shown, the drainage trough of this inverted M-shaped coil structure includes a coil assembly 1, a coil body 11, a coil end plate 12, a coil reinforcement plate 13, a coil base 2, a flat portion 21, an inclined portion 22, a first support portion 23, a second support portion 24, a drainage trough 3, a drainage hole 31, an outer edge 32, a drainage trough side sealing plate 4, a rivet nut 5, a drainage pipe 6, a rivet nut hole 7 and a coil fixing hole 8.

[0029] Reference Attachment Figure 6 、 7 The coil base 2 has a flat surface portion 21 parallel to the horizontal plane and an inclined surface portion 22 connected to the left side of the flat surface portion 21. Figure 1 As shown, there are two groups of coil bases 2, which are symmetrical and spaced apart from each other, so that the inclined portions 22 of the two groups face each other.

[0030] like Figure 1 、 4 As shown, the coil assembly 1 includes a coil body 11 and coil end plates 12 provided at both ends of the coil body 11. There are four groups of coil assemblies 1, two of which are close to each other and fixed to the inclined surface 22 of the two groups of coil bases 2, and the other two groups of coil assemblies 1 are fixed to the flat surface 21 of the two groups of coil bases 2. The four groups of coil assemblies 1 together form an inverted "M" structure. Figure 1 、 2 As shown, the drainage trough 3 is fixedly connected below the inclined portion 22 of each set of coil bases 2 , and the drainage trough 3 is used to collect condensed water that falls along the inclined portion 22 of the coil assembly 1 .

[0031] Furthermore, the right side of the plane portion 21 (i.e., the side away from the inclined portion 22) is connected to a first support portion 23 with an L-shaped cross section for support, and the left side of the inclined portion 22 (i.e., the side away from the plane portion 21) is connected to a second support portion 24 with an L-shaped cross section for support. The lower end surfaces of the first support portion 23 and the second support portion 24 are flush. Several rivet nut holes 7 are evenly opened along the surface of the second support portion 24, such as Figure 3 As shown, rivet nut holes 7 are also provided on the outer edge 32 of the drain trough 3 in a one-to-one correspondence, so that the second support portion 24 and the drain trough 3 are fixed by rivet nuts 5. The side fixation rather than the bottom fixation is adopted to effectively avoid the risk of bottom leakage.

[0032] Reference Attachment Figure 2 、 5 , 6, a plurality of coil fixing holes 8 are provided at both ends of the flat surface portion 21 and the inclined surface portion 22, and corresponding coil fixing holes 8 are also provided on the coil end plate 12, so that the coil assembly 1 is fixed to the flat surface portion 21 and the inclined surface portion 22 through the coil end plate 12.

[0033] Preferably, if Figure 4 As shown, a coil reinforcement plate 13 is installed at the middle position of the coil assembly 1 to reinforce the structure. Figure 3 As shown, a drainage trough side cover plate 4 is welded and fixed at both ends of the drainage trough 3. By welding, the processing difficulty of the drainage trough 3 is effectively reduced. A drainage hole 31 is opened at the bottom of the drainage trough 3 for installing a drainage pipe 6 to drain the collected condensed water outside the unit.

[0034] The working process of this utility model:

[0035] First, press the rivet nut 5 onto the outer edge 32 of the drain trough 3, then weld the drain trough side sealing plate 4 to both ends of the drain trough 3, and then fix it through the rivet nut 5 on the outer edge 32 of the drain trough 3 and the coil base 2 (rivet nut hole 7 on the second support portion 24). The four sets of coil assemblies 1 are fixed to the coil base 2 through the coil fixing holes 8, so that the drain trough 3 is just at the bottom of the coil assembly 1, effectively collecting condensed water. This solves the problem that traditional drain troughs are difficult to process and manufacture due to the excessive length of the unit, and the fixing holes at the bottom of the drain trough will leak, which will have a corrosive effect on the electrical components or sheet metal inside the unit. In addition, the drainage trough design of the inverted M-shaped coil structure does not add additional costs on the basis of the original structure, and effectively utilizes the inverted M-shaped slope structure of the coil itself to collect condensed water, which is an ideal drainage trough structure.

[0036] It is understandable that for those skilled in the art, any equivalent replacement or change of the technical solution and the concept of the utility model should fall within the scope of protection of the claims attached to the utility model.
