Description

Technical Field

[0001] The utility model relates to the field of stainless steel pipes, and in particular to a wear-resistant and high-strength composite stainless steel pipe for wind power stations. Background Art

[0002] Wear-resistant high-strength composite stainless steel pipe for wind power stations is a high-performance piping material designed specifically for wind power stations. It combines the corrosion resistance of stainless steel with the wear resistance of high-strength materials to meet the special requirements of wind power stations for piping materials.

[0003] Wind power station cooling systems typically require pipes to transport cooling media, such as cooling water or coolant. Composite stainless steel pipes offer excellent wear and corrosion resistance, meeting the cooling system's piping material requirements.

[0004] However, the existing wear-resistant and high-strength composite stainless steel pipes used in wind power stations cannot dissipate the heat of the coolant well during the coolant transportation process, which puts a heavy burden on the radiator. At the same time, when subjected to external pressure, they are prone to deformation or even rupture, thus affecting the transportation of the coolant.

[0005] Therefore, it is very necessary to invent a wear-resistant and high-strength composite stainless steel pipe for wind power stations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a wear-resistant and high-strength composite stainless steel pipe for a wind power station, comprising an external heat dissipation flat tube, an internal support flat tube and a stainless steel core tube. The external heat dissipation flat tube is compositely fixedly installed on the outside of the internal support flat tube, and a plurality of stainless steel core tubes are evenly compositely installed on the inside of the internal support flat tube.

[0007] The outer surface of the external heat-dissipating flat tube and the inner surface of the stainless steel core tube are both provided with a wear-resistant coating.

[0008] A plurality of through holes are evenly opened inside the inner supporting flat tube, and the stainless steel core tube is fixedly installed in the corresponding through holes. The outer surface of the stainless steel core tube and the through holes are sealed.

[0009] The outer surface of the inner supporting flat tube is evenly provided with a plurality of reinforcing ribs of the same shape as the inner supporting flat tube. The reinforcing ribs are located between the outer heat dissipating flat tube and the inner supporting flat tube, and a plurality of cavities are formed between the reinforcing ribs, the outer heat dissipating flat tube and the inner supporting flat tube.

[0010] A plurality of air holes are evenly opened on the surface of the reinforcing rib, the directions of the air holes are consistent with the directions of the ports of the inner supporting flat tubes, and the air holes are connected with the cavity.

[0011] The outer surface of the outer heat dissipating flat tube is uniformly provided with a plurality of heat dissipating grooves of the same shape as the outer heat dissipating flat tube, and the heat dissipating grooves are not communicated with the interior of the outer heat dissipating flat tube.

[0012] A ventilation hole is provided on each side of the surface of the outer heat dissipating flat tube close to the port. The ventilation hole is communicated with the cavity. A filter structure is detachably fixedly installed in the ventilation hole of the outer heat dissipating flat tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The overall arrangement of the utility model can cool the coolant during the transportation process when transporting the coolant required by the wind power station, and at the same time can improve the strength of the stainless steel core tube to avoid deformation and rupture of the stainless steel core tube when subjected to pressure. If the stainless steel core tube is accidentally ruptured, it will not affect the normal operation of other stainless steel core tubes. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example:

[0024] As attached Figure 1 To the attached Figure 4 As shown:

[0025] The utility model provides a wear-resistant and high-strength composite stainless steel pipe for a wind power station, comprising an external heat dissipation flat tube 1, an internal support flat tube 2 and a stainless steel core tube 3. The external heat dissipation flat tube 1 is compositely fixedly installed on the outside of the internal support flat tube 2. The arrangement of the external heat dissipation flat tube 1 and the internal support flat tube 2 can improve the overall heat dissipation capacity and at the same time improve the protection strength of the stainless steel core tube 3. The interior of the internal support flat tube 2 is evenly compositely installed with a plurality of stainless steel core tubes 3. The arrangement of the stainless steel core tubes 3 can disperse the coolant when conveying the coolant, increase the contact area with the coolant, thereby improving the heat dissipation effect of the coolant and reducing the pressure of the radiator.

[0026] The outer heat dissipation flat tube 1 and the inner support flat tube 2 are made of existing materials, such as titanium alloy, alloy steel, aluminum alloy, etc.

[0027] The outer surface of the outer heat dissipating flat tube 1 and the inner surface of the stainless steel core tube 3 are both provided with a wear-resistant coating. The provision of the wear-resistant coating can improve the wear resistance of the outer surface of the outer heat dissipating flat tube 1 and improve the wear resistance of the inner surface of the stainless steel core tube 3 when the stainless steel core tube 3 transports coolant.

[0028] The stainless steel core tube 3 is made of existing materials, such as 316L, 317L, etc.

[0029] In this embodiment, a number of through holes 8 are evenly opened inside the inner supporting flat tube 2, and the stainless steel core tube 3 is fixedly installed in the corresponding through hole 8. The outer surface of the stainless steel core tube 3 and the through hole 8 are sealed to facilitate better heat transfer. At the same time, if a stainless steel core tube 3 breaks, the coolant will not leak, so that the pipeline can still operate normally.

[0030] In this embodiment, the outer surface of the inner supporting flat tube 2 is evenly provided with a plurality of reinforcing ribs 4 of the same shape as itself to improve the overall strength. The reinforcing ribs 4 are located between the outer heat dissipating flat tube 1 and the inner supporting flat tube 2. A plurality of cavities are formed between the reinforcing ribs 4, the outer heat dissipating flat tube 1 and the inner supporting flat tube 2. The provision of the cavities allows a certain amount of deformation space when subjected to pressure, while facilitating ventilation and heat dissipation.

[0031] In this embodiment, a plurality of air holes 9 are evenly formed on the surface of the reinforcing rib 4 to facilitate air circulation in the cavity. The orientation of the air holes 9 is consistent with the orientation of the ports of the inner supporting flat tube 2, and the air holes 9 are connected to the cavity.

[0032] In this embodiment, the outer surface of the outer heat dissipating flat tube 1 is uniformly provided with a plurality of heat dissipating grooves 5 of the same shape as itself, so as to increase the contact area with the air and better perform heat exchange. The heat dissipating grooves 5 are not connected to the interior of the outer heat dissipating flat tube 1.

[0033] In this embodiment, a ventilation hole 6 is formed on each side of the surface of the external heat dissipating flat tube 1 near the port, so that external air can enter the cavity through the ventilation hole 6 and discharge heat from the cavity. The ventilation hole 6 is connected to the cavity. A filter structure 7, such as an activated carbon filter element, is detachably fixedly installed in the ventilation hole 6 of the external heat dissipating flat tube 1. The provision of the filter structure 7 can prevent impurities in the air from entering the cavity, thereby ensuring the overall heat dissipation capacity.

[0034] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
