Description

Technical Field

[0001] The utility model relates to a cabinet, in particular to a cabinet with an L-shaped surrounding frame. Background Art

[0002] Cabinets are common equipment in the power electronics industry, which contain electronic components. To meet the heat dissipation requirements of the electronic components inside the cabinet, several cooling fans are usually installed on the top of the cabinet. The number of fans ranges from one to dozens, depending on the size of the cabinet and the difference in heat dissipation requirements. Cabinets are usually tied with ropes during transportation. To prevent these fans from being damaged by the squeezing force of the ropes, a frame is installed on the top edge of the cabinet to directly contact the ropes and disperse the squeezing force of the ropes. The frame protects the fans.

[0003] The top of the existing cabinet is usually installed with a sheet metal frame. The cabinet structure with a sheet metal frame can be seen in Figure 1 and Figure 2 , including a cabinet 1, and a fan 2 and a sheet metal enclosure 03 arranged on the top of the cabinet 1, wherein the sheet metal enclosure 03 is arranged around a peripheral edge of the top of the cabinet 1, and the sheet metal enclosure 03 includes a sheet metal enclosure frame 031 of a semi-enclosed structure and a sheet metal enclosure cover 032 arranged outside the sheet metal enclosure frame 031, wherein the semi-enclosed direction faces the inner side of the cabinet 1, the sheet metal enclosure frame 031 is a thick sheet metal, the sheet metal enclosure cover 032 is a thin sheet metal, and the sheet metal enclosure cover 032 located at the bottom of the sheet metal enclosure 03 is connected to the top of the cabinet 1. During processing, four sheet metal strips are first made, and then the four sheet metal strips are welded to form the sheet metal enclosure 03. However, the problems existing in the prior art are: the strength of the sheet metal enclosure 03 is low; there are two bending processes in the process of processing the sheet metal into the sheet metal enclosure 03, and the processing cost is high; and the fillet radius of the bending part of the processed sheet metal enclosure 03 is large, which cannot meet the requirements of strength and aesthetics. Utility Model Content

[0004] The utility model aims to solve the problems that the sheet metal surrounding frame on the top of the existing cabinet has high processing cost and cannot meet the strength and aesthetic requirements, and provides a cabinet with an L-shaped surrounding frame.

[0005] To achieve the above purpose, the technical solution provided by the utility model is:

[0006] A cabinet with an L-shaped frame includes a cabinet and a plurality of fans arranged on the top of the cabinet, and the special features thereof are:

[0007] It also includes a surrounding frame arranged around the edge of the top of the cabinet; the surrounding frame includes an L-shaped piece arranged around the edge of the top of the cabinet and a square tube arranged around the upper inner surface of the vertical part of the L-shaped piece; the upper surface of the square tube is flush with the upper end of the L-shaped piece, the outer surface of the vertical part of the L-shaped piece is flush with the side of the cabinet, and the lower surface of the horizontal part of the L-shaped piece is connected to the top of the cabinet.

[0008] Furthermore, the L-shaped member is specifically an L-shaped angle steel which surrounds the edge of the top of the cabinet and is welded into a rectangular shape.

[0009] Furthermore, the square tube and the L-shaped member are connected by welding.

[0010] Furthermore, the lower surface of the horizontal part of the L-shaped member is connected to the top of the cabinet by a fastener, which has the advantage of being easy to disassemble and assemble.

[0011] Furthermore, the cross section of the square tube is a square.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The cabinet with an L-shaped frame provided by the utility model has an L-shaped part which is a standard profile, and the fillet radius at the bending part is very small, which has good adaptability to the cabinet and can meet the requirements of aesthetics; at the same time, the L-shaped part only has a welding process in the processing process, and there is no bending process, which saves processing costs;

[0014] 2. The cabinet with an L-shaped frame provided by the utility model adopts an L-shaped part with a thicker wall thickness and is matched with a square tube. The square tube can make up for the insufficient bending resistance of the top end of the L-shaped part. The two together play a role in resisting the squeezing force of the hanging rope, which can ensure that the cabinet, the fan arranged on the top of the cabinet and the L-shaped part itself are not damaged, and the reliability is high.

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] A cabinet with an L-shaped frame, see Figure 3 to Figure 4 , comprising a cabinet 1, two fans 2 arranged on the top of the cabinet 1, and a surrounding frame 3 arranged around the edge of the top of the cabinet 1;

[0025] The frame 3 includes an L-shaped member 31 arranged around the top edge of the cabinet 1 and a square tube 32 welded around the upper inner surface of the vertical part of the L-shaped member 31; the upper surface of the square tube 32 is flush with the upper end of the L-shaped member 31, the outer surface of the vertical part of the L-shaped member 31 is flush with the side of the cabinet 1, and the lower surface of the horizontal part of the L-shaped member 31 is connected to the top of the cabinet 1 by bolts.

[0026] The L-shaped member 31 is an L-shaped angle steel welded into a rectangle, and the square tube 32 is a standard profile. In actual application scenarios, according to the size of the cabinet 1 and the difference in heat dissipation requirements, the number of fans 2 arranged on the top of the cabinet 1 ranges from one to dozens.

[0027] In this embodiment, the width of the horizontal part of the L-shaped member 31 is 50 mm, the height of the vertical part is 75 mm, and the thickness of the horizontal part and the vertical part are both 5 mm; the wall thickness of the square tube 32 is 1.5 mm, the cross-section of the square tube 32 is a square, and the side length of the square is 20 mm.

[0028] Meanwhile, the curvature radius of the bending fillet of the connection portion between the sheet metal frame and the cabinet 1 in the prior art is usually 2 mm, while the curvature radius of the bending fillet of the connection portion between the sheet metal frame and the cabinet 1 in this embodiment is 0.5 mm, which is more aesthetically pleasing.

[0029] In this embodiment, the fillet radius of the L-shaped member 31 at the bending part is very small, and it has good adaptability with the cabinet 1, which can meet the aesthetic requirements; at the same time, the L-shaped member 31 only has a welding process during the processing, and there is no bending process, which saves processing costs; and this embodiment adopts an L-shaped member 31 with a thicker wall thickness, and is equipped with a square tube 32. The square tube 32 can make up for the insufficient bending strength of the top of the L-shaped member 31. The two together play a role in resisting the squeezing force of the hanging rope, which can ensure that the cabinet 1, the fan 2 set on the top of the cabinet 1 and the L-shaped member 31 itself are not damaged, and the reliability is high.

[0030] It should be noted that the above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be included in the protection scope of the present invention.
