Detailed Description

The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and merely illustrates the basic structure of the present invention in a schematic manner, and therefore it shows only the constitution related to the present invention.

As shown in fig. 1-3, the utility model discloses a withstand voltage water cooling cover of reinforcing, including barrel 1, barrel 1 includes urceolus 2 and coaxial setting at the inside inner tube 3 of urceolus 2, the cross-section of inner tube 3 and urceolus 2 is the rectangle, and forms cooling chamber 7 between inner tube 3 outer wall and the 2 inner walls of urceolus, and cooling chamber 7 lets in the circulating water and plays the cooling effect. The impact force of the circulating water in the cooling cavity 7 on the outer barrel 2 is changed due to the fact that the shape of the barrel 1 is changed from circular to rectangular. Due to the circular structure, the circular arc has the maximum compatibility to deformation, so that after the circular arc is impacted, the deformation of each position is the same, and the deformation caused by uneven stress cannot occur. For the rectangular cylinder 1, four surfaces are in a planar structure, the four corners are connected by side walls, the shock resistance is strongest, and the shock resistance is the worst by the middle position, so that the cylinder 1 in the rectangular structure is easy to cause the middle deformation, in order to reduce the deformation, a plurality of annular reinforcing ribs 4 are axially distributed on the inner wall of the outer cylinder 2, the annular reinforcing ribs 4 are welded on the inner wall of the outer cylinder 2, and the compressive strength is improved by the annular reinforcing ribs 4; because the circulating water needs to flow circularly from the cooling cavity 7, enough space needs to be reserved for the circulating water to pass through while ensuring the strength, and the influence on the cooling effect is avoided, so that the width of the annular reinforcing rib 4 in the radial direction is 1/4 to 3/4 of the width of the cooling cavity 7 between the inner cylinder 3 and the outer cylinder 2.

The larger the plane area is, that is, the longer the side length of the cylinder 1 is, the larger the deformation caused by the same impact force is, so that the widths of the cooling cavities 7 in four directions of the cylinder 1 with the square structure are equal, and the widths of the annular reinforcing ribs 4 are also equal. As shown in fig. 2, when the cylindrical body 1 has long sides a and short sides b, in order to reduce the influence on the long sides a, the width H2 of the cooling cavities 7 on the long sides is smaller than the width H1 of the cooling cavities 7 on the short sides. The width L2 of the annular reinforcing rib 4 on the long side is more than or equal to 1/2 of the width H2 of the cooling cavity 7 on the long side, and 3/4 is preferred in the embodiment; the width L1 of the annular reinforcing rib at the short side is 1/4 to 3/4 of the width of the cooling cavity at the short side, and the preferred width is 1/3 in the embodiment.

A first end cover 5 and a second end cover 6 are respectively welded at two ends of the cylinder body 1 to seal the cooling cavity 7, and a welding seam 8 is formed at the welding position. Preferably, the width of the weld bead 8 is 5 to 6mm in consideration of the soundness, efficiency, and cost. The outer barrel 2 is also provided with a water inlet and a water outlet for the inlet and outlet of cooling water.

The working principle is as follows:

cooling water enters the cooling cavity 7 from the water inlet of the barrel 1 and flows along the arrow direction in fig. 3, when the cooling water passes through the annular reinforcing ribs 4, part of the water flow is blocked, so that the water flow velocity close to one side of the outer barrel 2 is lower than that close to the inner barrel 3, and the impact force of the water flow on the outer barrel 2 can be reduced through the blocking effect of the annular reinforcing ribs 4; in addition, the use of the annular bead 4 can directly improve the compressive strength of the outer cylinder 2 and further reduce the deformation due to impact. The cooling water flows out from the water outlet after passing through the cooling cavity 7, the heat generated by the devices inside the equipment is taken away, and the annular reinforcing ribs 4 have certain blocking effect on water flow, so that the water flow can fully carry out heat exchange, therefore, the heat dissipation efficiency can be effectively guaranteed, and the normal work of the devices of the equipment is guaranteed.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the scope of the invention. The technical scope of the present invention is not limited to the content of the description, and the technical scope must be determined according to the scope of the claims.
