Description

Technical Field

[0001] The utility model relates to refrigeration equipment, in particular to a refrigeration aluminum pipe fixing frame. Background Art

[0002] Aluminum finned tubes are often used in cold storage refrigeration systems, creating aluminum finned evaporators. Common fixing structures for aluminum finned tubes include connecting rods (support rods) that pass through the fins. For example, Chinese Invention Patent No. 2023100879874 discloses a novel aluminum finned tube for cold storage cooling. The vertical aluminum fins are penetrated by transverse support tubes. This solution requires holes in the fins and may even require bolts or welding to further secure the finned tubes. Another solution uses a bracket structure to secure the finned tubes. For example, Chinese Utility Model Patent No. 2021224366710 discloses an energy-efficient, high-efficiency aluminum alloy top finned tube for supplying liquid to a barrel pump unit. This uses angle steel as a support beam, and plastic brackets secure the finned tubes to the support beam. However, further measures, such as bolts, are required to secure the finned tubes to the support beam. These solutions are inconvenient in terms of finned tube installation and may also hinder mechanized defrosting operations. Utility Model Content

[0026] like Figures 1 to 9 A refrigeration aluminum pipe fixing frame includes a card keel 10 and a hook piece 20.

[0027] The card keel 10 is a U-shaped structure consisting of a first vertical wall 1a, a second vertical wall 1b, and a bottom plate 1c. The first and second vertical walls 1a and 1b are provided with grooves 19 for structural reinforcement. The card keel 10 is made of 1mm or 1.2mm thick steel plate.

[0028] A plurality of first engaging protrusions 14 are provided on the first vertical wall 1a. These protrusions 14 protrude beyond the upper edge 15 of the clip-on keel. Each first engaging protrusion 14 is provided with a first fin engaging slot 11. A hooking slot 12 is provided on the first sidewall of the first fin engaging slot 11, and a pressing slot 13 is provided on the other sidewall of the first fin engaging slot 11. The hooking slot 12 and the pressing slot 13 are positioned correspondingly. The width K2 of the pressing slot 13 is greater than the width K1 of the hooking slot 12.

[0029] Multiple second retaining projections 17 are provided on the second vertical wall 1b. These projections 17 correspond one-to-one with the first retaining projections 14, and they protrude beyond the upper edge 15 of the card-type keel. Second fin retaining slots 16 are provided on these projections 17. These second fin retaining slots 16 correspond one-to-one with the first fin retaining slots 11. The width K4 of the second fin retaining slots 16 is equal to the width K3 of the first fin retaining slots 11. The widths of the first and second fin retaining slots are slightly larger than those of the aluminum fins 31, allowing them to fit into the first and second fin retaining slots.

[0030] The bottom plate 1c of the card-type keel is provided with a plurality of hoisting holes 18 for connecting the hoisting rods to hoist the refrigeration aluminum pipes on the cold storage.

[0031] The hook piece 20 is a steel sheet and has an arcuate hook 22 and a hook arm 23. The arcuate hook 22 is a gradually tapering arc. The outer edge of the arcuate hook 22 is formed by the extruded edge 21 of the aluminum fin 31. The tail of the hook arm 23 is provided with a hook 24, which can be inserted into the aluminum fin 31. The width K1 of the hook slot 12 is greater than the thickness S of the hook piece 20, allowing the hook piece 20 to be inserted into the hook slot 12.

[0032] In this embodiment, the aluminum tube 30 is a multi-row aluminum tube bent in an S shape. During the installation of the aluminum tube, a first fin slot 11 of the card keel 10 corresponds to an aluminum tube fin 31. Figure 5 Insert multiple aluminum tube fins 31 into a first fin slot 11, and insert the aluminum tube fins 31 into a second fin slot 16. Figure 6 The front end width S1 of the arc hook 22 of the hook piece 20 is smaller than the length K5 of the hook piece slot 12. The arc hook 22 is inserted into the hook piece slot 12 from the front end. Figure 7 As shown. Move the hook arm 23 toward the aluminum tube fins and appropriately press the hook arm 23 downward so that the hook 24 passes over the lower edge of the aluminum tube fins 31 and is clamped on the opposite side of the aluminum tube fins 31. The width S2 of the tail of the arc hook 22 is greater than the length K5 of the hook slot, so that the extrusion edge 21 of the hook can squeeze the aluminum tube fins 31. During the rotation of the arc hook 22, the tail of the arc hook presses into the aluminum tube fins 31, squeezing out a protrusion 32 on the other side of the aluminum tube fins 31 that fits into the compression groove 13, as shown. Figure 8 、 Figure 9 As shown. This ensures a secure connection between the aluminum tube and the card keel 10. Since the tail of the arc-shaped hook 22 is pressed into the aluminum tube fin 31, the hook 24 is stuck on the opposite side of the aluminum tube fin 31, and the hook piece 20 will not fall off, maintaining a secure connection between the aluminum tube and the card keel.

[0033] The present invention utilizes a profiled card-type keel 10, which, compared to conventional steel profiles (such as angle steel, channel steel, and I-beam), offers advantages of lightness and high load-bearing capacity. The use of hooks 20 to secure the aluminum tubes eliminates the need for drilling holes in the tubes, thus preventing damage to their structure. Furthermore, the use of bolts or other fasteners to secure the tubes is unnecessary, making installation easier and significantly improving installation efficiency.

[0034] Since the card keel 10 adopts the card slot protrusion structure (first card slot protrusion, second card slot protrusion), the lower edge of the aluminum tube fin is higher than the upper edge 15 of the card keel, the roller brush 41 of the defrost mechanism 40 can pass through the card keel 10 via the card slot protrusion, so that the defrost mechanism 40 can operate normally. Figure 10 In addition, due to the structure of the card slot and protrusion, the card keel 10 can also be installed with the multi-fin aluminum tube 50, and the card keel will not interfere with the multi-fin aluminum tube. Figure 11 shown.
