Referring to fig. 8, 9 and 10, fig. 8 is a schematic perspective view of the end cap of the present invention; FIG. 9 is a schematic perspective view, partially in section, of the end cap shown in FIG. 8; FIG. 10 is an enlarged cross-sectional view of the end cap shown in FIG. 8; an embodiment of the end cap for a plenum of a blow-molded cooling device of the present invention comprises a first sheet metal 2 and a second sheet metal 3.
The first metal sheet 2 is a disc-shaped thin steel plate having a thickness of 2 mm. The thickness of the first metal sheet is not limited to 2mm, and is preferably in the range of 0.8mm to 5mm, for example, 1.5mm, 2.5mm, 3mm, etc., and may be 4mm, 4.5mm, etc., in consideration of the factors such as the diameter, strength, thickness, weight, etc., so that the best balance can be obtained.
The first metal sheet 2 has a central through hole 20 at the center thereof, and thus the first metal sheet 2 has a first inner edge fixing portion 21 and a first outer edge fixing portion 22 in the radial direction. Around the central through hole 20, the first metal sheet 2 is further provided with at least one first bent portion. Wherein the bending part is defined as forming the bending part as long as the two surfaces are not on the same plane.
The second metal sheet 3 is similar in structure to the first metal sheet 2: the second metal sheet 3 is a disc-shaped thin steel plate having a thickness of 2 mm. The thickness of the second metal sheet 3 is not limited to 2mm, and is preferably in the range of 0.8mm to 5mm, for example, 1.5mm, 2.5mm, 3mm, etc., in consideration of the diameter, strength, thickness, weight, etc., but may be 4mm, 4.5mm, etc., so that the strength, thickness, weight, etc. can be balanced optimally. The second metal sheet 3 has a central through hole 30 at the center thereof, and thus the second metal sheet 3 has a second inner edge fixing portion 31 and a second outer edge fixing portion 32 in the radial direction. Around the central through hole 30, the second metal sheet 3 is further provided with at least one second bent portion. The diameter of the central through hole 30 of the second metal sheet 3 is the same as the diameter of the central through hole 20 of the first metal sheet 2.
The second metal sheet 3 is disposed below the first metal sheet 2, the first inner edge fixing portion 21 of the first metal sheet 2 is fixedly connected with the second inner edge fixing portion 31 of the second metal sheet 3, the first outer edge fixing portion 22 of the first metal sheet 2 is fixedly connected with the second outer edge fixing portion 32 of the second metal sheet 3, and a hollow portion is formed between the first metal sheet 2 and the second metal sheet 3.

Further, the second bending portion of the second metal sheet 3 further includes a reinforcing portion 36 connected to the inner mounting groove 34 and protruding in a direction away from the first metal sheet 2. The depth of the reinforcement 36 is less than the depth of the inner mounting groove 34 so that the thickness T1 of the end cap at the central through hole can be less than the thickness T2 at the outer edge, which can further reduce the weight of the end cap; more importantly, the thickness T1 at the central through hole is easy to adjust, for example, by increasing the height of the first inner edge fixing portion 21 of the first metal sheet 2 (in the present invention, the height and the thickness are in the same direction), the size of the thickness T1 can be changed, so the height of the "windless zone" can be easily changed by designing the size of the thickness T1 at the central through hole.
As shown in fig. 11, the first bent portion of the first metal sheet 2 includes a gasket groove 23 that is annular and recessed toward the second metal sheet 3 and a strength reinforcing groove 24 that is annular and recessed toward the second metal sheet 3.

A part of the inner mounting groove 34 of the second metal sheet 3 and the strength reinforcing groove 24 of the first metal sheet 2 are in contact and fixedly connected with each other. The outer mounting groove 33 and the sealing gasket groove 23 are staggered with each other to partially improve the overall structural strength and rigidity of the end cover, and the outer mounting groove 33 and the sealing gasket groove 23 can be completely staggered under the condition that the thickness of the first metal sheet 2 and the second metal sheet 3 is thicker or the overall diameter of the end cover is smaller. In addition, since the second metal sheet 3 and the first metal sheet 2 are in contact with each other, a plurality of hollow portions are formed between the second metal sheet 3 and the first metal sheet 2, for example, one hollow portion is formed between two adjacent contact positions, and one hollow portion is formed between each of the contact positions and the inner edge and the outer edge of the end cover, so that not only is the weight effectively reduced, but also the structural strength of the end cover is greatly improved. As shown in fig. 5, the top end flange 422 of the rectifying outer cylinder 42 is provided in the outer mounting groove 33, and a gasket 231 may be provided between the top end flange 422 and the outer mounting groove 33. The upper flange 46 of the inner fairing cylinder assembly is positioned in the inner mounting groove 34 and a gasket may be positioned therebetween.
As shown in fig. 11, the first inner edge fixing portion 21 is vertically bent toward the second inner edge fixing portion 31, the second inner edge fixing portion 31 is vertically bent toward the first inner edge fixing portion 21, and the first inner edge fixing portion 21 and the second inner edge fixing portion 31 are bonded together and fixedly connected in the diameter direction along the end cap; the first outer edge fixing portion 22 is vertically bent toward the second outer edge fixing portion 32, and the second outer edge fixing portion 32 is vertically bent toward the first outer edge fixing portion 22, and the first outer edge fixing portion 22 and the second outer edge fixing portion 32 are bonded together and fixedly connected along the diameter direction of the end cap, that is, the contact area between the first metal sheet 2 and the second metal sheet 3 is large at the inner edge and the outer edge of the end cap, so that the fixing is firm and the strength is large.
As shown in fig. 9 and 11, a plurality of first vias 25 are uniformly provided on the first metal sheet 2 along the outer circumferential direction, a plurality of second vias 35 are uniformly provided on the second metal sheet 3 along the outer circumferential direction in one-to-one correspondence with the plurality of first vias 25, and the diameter of the second vias 35 is smaller than the diameter of the first vias 25. A bolt (not shown) may be inserted through the corresponding first and second vias 25 and 35 to mount the end cap to the plenum housing of the plenum. The end cover with the through hole, namely the bolt hole, can be conveniently replaced with the end cover of the traditional air chamber through the dismounting of the bolt. Of course, the end cap of the present invention does not necessarily contain a via, and the end cap may be secured to the plenum housing by welding or other means.
