[0001] The invention belongs to the technical field of radiators, and in particular relates to a plate-type radiator. Background Art

[0002] A transformer is an electrical device used to change the voltage of alternating current. When the transformer is working, it usually generates heat, which is dangerous and needs to be cooled down in time. The method of cooling the transformer is usually to install a radiator on its case to dissipate heat. Plate radiators are more common transformer cooling devices. Generally speaking, plate radiators are also connected to a circulating cooling system to further cool the transformer.

[0003] The existing fin radiator has limited circulation cooling effect and cannot improve the cooling effect. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a plate-type heat sink, comprising:

[0006] An oil collecting pipe and a heat sink, wherein the oil collecting pipe is connected to the transformer, and the oil collecting pipe is connected to a plurality of vertical heat sinks, and the plurality of heat sinks are arranged in parallel;

[0007] The heat sink comprises a first plate and a second plate, the first plate and the second plate are connected circumferentially to form an oil passage chamber, and a connection area is provided between the first plate and the second plate to form an oil passage line from top to bottom in the oil passage chamber;

[0008] The first plate and the second plate are both arched outwardly to form a convex portion, and the convex portion corresponds to the oil passage line to increase the diameter of the oil passage line.

[0009] Furthermore, the cross-section of the protrusion is wavy to form adjacent enlarged oil flow lines.

[0010] Furthermore, the lowest trough of the protrusion is higher than the height of the outward side of the sheet.

[0011] Furthermore, an oil separation connection portion is provided between the first plate and the second plate, the oil separation connection portion is provided between the oil passing line and the oil collecting pipe, and the oil separation connection portion is in a connection and merging shape between the first plate and the second plate;

[0012] The oil-dividing connection portion comprises a first inclined connection area, a middle arc-shaped area and a second inclined connection area which are connected in sequence, so as to divide the oil in the oil collecting pipe into the oil-passing lines at the sides.

[0013] Furthermore, the curvature of the middle arc-shaped area is the curvature below the oil collecting pipe.

[0014] Furthermore, the first inclined connection area is inclined downward in a direction away from the middle arc-shaped area, and the inclination angle is 5-10 degrees.

[0015] Furthermore, the second inclined connection area is inclined downward in a direction away from the middle arc-shaped area, and the inclination angle is 5-10 degrees.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example:

[0037] like Figures 1 to 3 As shown, a fin type radiator comprises: an oil collecting pipe 1 and radiating fins 2, wherein the oil collecting pipe 1 is connected to a transformer, and the oil collecting pipe 1 is connected to a plurality of vertical radiating fins 2, and the plurality of radiating fins 2 are arranged in parallel. The lubricating oil in the transformer is collected in the oil collecting pipe 1, and the oil collecting pipe 1 is transported outward, and the lubricating oil flows downward from the oil collecting pipe 1 into the radiating fins 2, and the radiating fins 2 dissipate heat by increasing the contact area with the air.

[0038] like Figures 1 to 3 As shown, the heat sink 2 includes a first plate 21 and a second plate 22, the first plate 21 and the second plate 22 are circumferentially connected, and the space between the first plate 21 and the second plate 22 forms an oil passage chamber 3. A connecting area is set between the first plate 21 and the second plate 22 to connect the first plate 21 and the second plate 22. Lubricating oil cannot pass through the connecting area, thereby dividing the oil passage chamber 3 into a plurality of oil passage lines 4 from top to bottom.

[0039] Among them, the first plate 21 and the second plate 22 are both arched with a protrusion 5 on the outward side, and the protrusion 5 corresponds to the oil-passing line 4 to increase the diameter of the oil-passing line 4. The cross-section of the protrusion 5 is wavy to form an adjacent enlarged oil-passing line 4. The lowest trough of the protrusion 5 is higher than the height of the outward side of the plate. The oil-passing line 4 formed by the first plate 21 and the second plate 22 with a wavy cross-section can be enlarged, and the volume of the chamber formed by the wavy first plate 21 and the second plate 22 becomes larger, thereby improving the oil-passing efficiency.

[0040] like Figure 1 As shown in Figure 3, an oil separation connection part 6 is provided between the first plate 21 and the second plate 22. The oil separation connection part 6 is provided between the oil passing line 4 and the oil collecting pipe 1. The oil separation connection part 6 is a connection and merging shape between the first plate 21 and the second plate 22; the oil separation connection part 6 includes a first inclined connection area 61, a middle arc area 62, and a second inclined connection area 63 connected in sequence, so as to separate the oil in the oil collecting pipe 1 into the oil passing line 4 on the side. Among them, the curvature of the middle arc area 62 is the curvature below the oil collecting pipe 1. The first inclined connection area 61 is inclined downward in a direction away from the middle arc area 62, and the inclination angle is 5-10 degrees. The second inclined connection area 63 is inclined downward in a direction away from the middle arc area 62, and the inclination angle is 5-10 degrees. The lubricating oil is collected through the oil collecting pipe 1 and input downward into the oil passage chamber 3. The lubricating oil passes through the resistance of the middle arc-shaped area 62, flows to both sides, and then passes through the resistance of the first inclined connection area 61 and the second inclined connection area 63, and flows to both sides of the oil passage chamber 3, so that the lubricating oil first flows downward in the oil passage line 4 on the side to dissipate heat, and then gradually converges to the oil passage line 4 in the center part. The heat dissipation effect of the lubricating oil through the oil passage lines 4 on both sides is improved. As is known to all, the sheet radiator is provided with several sheets, the distance between adjacent sheets is close, and the lubricating oil all passes through the oil passage line 4 in the sheet in the middle part, so the heat dissipation effect of the middle part is poor, and it is not easy to dissipate heat outward. The present application divides the oil through the oil separation connection part 6, so that the lubricating oil passes through both sides first, which can not only avoid the middle area that is not easy to dissipate heat, but also be close to the side, so that the heat of the lubricating oil can be better dissipated outward, thereby improving the heat dissipation efficiency. When the side oil passages 4 are full, the lubricating oil can also overflow into the middle oil passages 4, making full use of the overall space between the first plate 21 and the second plate 22 to improve the heat dissipation efficiency.

[0041] like Figure 1 As shown in Figure 3, the oil-passing line 4 includes a plurality of vertical large areas 41, and a plurality of vertical welding connecting strips 42 are arranged in the vertical large areas 41; and a partition welding strip 43 is arranged between adjacent vertical large areas 41. There are seven vertical large areas 41, which are partitioned by six partition welding strips 43. The two middle partition welding strips 43 are lower than the partition welding strips 43 on the sides.

[0042] In summary, by adding the raised portion 5, the oil flow path can be enlarged, thereby increasing the oil flow rate, improving the oil flow efficiency, and increasing the oil flow rate, allowing the lubricating oil to be quickly discharged from the transformer and cooled, thereby improving the cooling effect. The overall cooling effect is 15%-20% higher than the prior art. Through the oil separation connection portion 6, the lubricating oil can be evenly discharged into a plurality of oil flow lines 4, thereby improving the oil flow efficiency of the lubricating oil.

[0044]

[0045] Among them, Example 1 and Example 2 are the plate-type heat sinks of the present application, and Comparative Example 1 and Comparative Example 2 are the plate-type heat sinks of the prior art.

[0046] It can be concluded from the above table that the heat dissipation effect of the plate-type heat sink in this embodiment is 15%-20% higher than that of the plate-type heat sink in the comparative example.
