[0016] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0017] Please refer to Figures 1-3 As shown, the present utility model proposes a thermal control protection device for a thermal power unit, which includes a substrate 11, support columns 12, heat dissipation blocks 13, and a heat dissipation plate 20. The materials of the substrate 11, the support columns 12, the heat dissipation blocks 13, and the heat dissipation plate 20 are all aluminum, ensuring the heat dissipation protection performance of the components in terms of thermal control.

[0018] The support columns 12 are fixedly arranged at the corner ends of the substrate 11. Fasteners are used for connection inside the support columns 12, and the heat dissipation plate 20 is fixedly connected to the substrate 11 through fasteners. Specifically, connection legs 23 are arranged at the bottom of the heat dissipation plate 20, and the fasteners are connected to the connection legs 23, and the set connection legs 23 ensure the connection stability between the heat dissipation plate 20 and the substrate 11.

[0019] The heat sink 13 is fixedly arranged below the substrate 11, and the heat sink 13 is in close contact with the substrate 11. The heat dissipation plate 20 is arranged above the substrate 11.

[0020] The heat dissipation plate 20 is arc-shaped and the opening faces upward. The heat dissipation plate 20 is arc-shaped and the central angle corresponding to the heat dissipation plate 20 is 120°, which can effectively ensure the support of the heat dissipation plate 20 for the pipe fittings or components. Fins 21 are arranged on the surface of the heat dissipation plate 20 facing the substrate 11. The fins 21 are arranged at intervals along the outer diameter direction of the heat dissipation plate 20, and the fins 21 extend along the axial direction of the heat dissipation plate 20. Notches 22 are arranged on the fins 21, and a plurality of notches 22 are arranged at intervals along the length direction of the fins 21. The notches 22 are used to accommodate the connecting wires, and the pipe fittings supported on the heat dissipation plate 20 and the heat dissipation plate 20 are wound by the connecting wires.

[0021] The connecting wires are accommodated by the notches 22 and the surface of the pipe fittings and the heat dissipation plate 20 are adhered through the connecting wires, thereby improving the heat dissipation performance while ensuring the connection tightness. And setting the notches 22 can reduce the material consumption of the fins 21 to a certain extent, thereby reducing the weight of the heat dissipation plate 20.

[0022] Furthermore, setting the notches 22 can change the flow path of the air between the fins 21, making the air flow more smooth and diversified. The air can more easily enter the gaps between the fins 21 and fully contact the surface of the fins 21, thereby improving the heat exchange efficiency. For example, when the air flows through the fins 21 with the notches 22, local turbulence will be formed at the notches 22, enhancing the heat exchange effect between the air and the fins 21.

[0023] At the same time, the notches 22 can help adjust the temperature distribution on the heat dissipation plate 20. In the absence of the notches 22, heat may concentrate in certain areas, resulting in too high local temperature. The setting of the notches 22 can make the heat more evenly distributed on the fins 21, avoiding the occurrence of local overheating.

[0024] The notches 22 are semi-circular and are arranged on the side of the heat dissipation plate 20 facing the substrate 11. Ventilation holes 24 are arranged at the bottom of the heat dissipation plate 20. The ventilation holes 24 penetrate through the heat dissipation plate 20 and correspond to the substrate 11.

[0025] The heat dissipation of the pipe fittings supported by the heat dissipation plate 20 is jointly achieved through the heat dissipation plate 20 connected to the substrate 11 and the heat dissipation block 13. Among them, fins 21 are arranged on the lower side of the heat dissipation plate 20 to improve the heat dissipation performance of the heat dissipation plate 20, and corresponding notches 22 are arranged on the fins 21. And ventilation holes are arranged at the bottom of the heat dissipation plate 20 so that part of the air flow flows through the fins 21 and the ventilation holes 24 respectively, thereby realizing the heat dissipation treatment of the heat dissipation plate 20 for the pipe fittings on the inner and outer sides, thus ensuring the heat dissipation of the important components or pipelines of the thermal power unit and realizing the performance improvement of the thermal control protection, improving the effective heat dissipation of the important pipelines of the thermal power unit and ensuring the reliability of the thermal control management.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
