Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, specifically to a heat dissipation structure for the housing fins of an explosion-proof electric actuator. Background Technology

[0002] In highly hazardous environments such as petroleum, chemical, and coal mines, explosion-proof electric actuators, as critical control equipment, must simultaneously meet stringent explosion-proof sealing requirements and efficient heat dissipation needs. The core components of these devices, such as motors and control modules, generate a significant amount of heat during operation. Inadequate heat dissipation can easily lead to overheating, decreased operational stability, and even safety hazards. Furthermore, the airtightness requirements of the explosion-proof housing limit the application of traditional exposed heat dissipation structures, preventing the destruction of explosion-proof performance due to openings in the housing.

[0003] Existing heat dissipation solutions for explosion-proof equipment have several limitations: Firstly, some heat-conducting structures are directly connected to the shell using metal materials, which, while able to conduct heat, struggle to maintain insulation performance, potentially leading to leakage or electrical sparks. Secondly, the heat dissipation fins on the outer surface of the shell are mostly flat with uniform cross-sections, resulting in a simple surface structure and low convective heat dissipation efficiency, making it difficult to meet the heat dissipation requirements of high-power equipment. Furthermore, the balance between thermal conductivity and structural strength of traditional explosion-proof shell materials is difficult to achieve, further restricting heat dissipation effectiveness. Therefore, there is an urgent need for a structural design that can ensure the integrity of the explosion-proof seal, maintain insulation safety, and achieve efficient heat dissipation to meet the operational needs of high-power sealed explosion-proof equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a finned heat dissipation structure for the housing of an explosion-proof electric actuator, which can conduct the heat generated by the internal heating structure to the outside of the housing to achieve efficient heat dissipation.

[0005] The technical solution adopted in this utility model is: a heat dissipation structure for the housing fins of an explosion-proof electric actuator, comprising an explosion-proof housing, a heat conduction mechanism, and a heat dissipation mechanism; the heat conduction mechanism includes heat conduction columns uniformly arranged on the inner wall of the explosion-proof housing, each heat conduction column including an insulating section in contact with the inner wall of the explosion-proof housing, the insulating section being connected to a heat conduction section in contact with the heat-generating structure; the heat dissipation mechanism includes heat dissipation fins uniformly arranged on the outer surface of the explosion-proof housing, the surface of the heat dissipation fins being etched with heat dissipation grooves.

[0006] In this technical solution, the heat-conducting mechanism inside the explosion-proof housing is used to conduct heat generated by the heating structure to the outside of the explosion-proof housing. The heat-conducting section of the heat-conducting column is in direct contact with the heating structure, which is conducive to efficient heat conduction. At the same time, the insulating section is in contact with the inner wall of the explosion-proof housing, which on the one hand conducts heat to the surface of the explosion-proof housing, and on the other hand ensures the insulation effect. After the heat is conducted to the surface of the explosion-proof housing, it is dissipated through the heat dissipation mechanism. The heat dissipation fins are evenly arranged on the surface of the explosion-proof housing to achieve direct heat dissipation. The heat dissipation grooves arranged on the surface of the heat dissipation fins are used to enhance turbulent heat dissipation and improve the heat dissipation effect. It is suitable for high-power sealed explosion-proof equipment.

[0007] Preferably, the insulating section of the heat-conducting column is a ceramic column, and the heat-conducting section is a copper column.

[0008] Preferably, the bottom thickness of the heat dissipation fins is greater than the top thickness, forming variable cross-section fins.

[0009] Preferably, the surface of the heat dissipation fins is coated with a heat dissipation coating.

[0010] Preferably, the edges of the heat dissipation fins are provided with heat dissipation serrations.

[0011] Preferably, the explosion-proof housing is made by extrusion molding of an aluminum and graphene composite material.

[0012] The beneficial effects of this utility model are:

[0013] 1. The heat conduction mechanism of this utility model adopts a composite heat conduction column design of insulation section and heat conduction section to ensure the electrical insulation effect during the heat conduction process and avoid the risk of leakage or electric spark; the heat conduction section uses copper column to directly contact the heating structure, and utilizes the high thermal conductivity of copper to quickly absorb heat and conduct it to the insulation section, which solves the problem of insufficient insulation of traditional heat conduction structure.

[0014] 2. In this utility model, the heat dissipation fins of the heat dissipation mechanism are evenly arranged on the outer surface of the explosion-proof shell, thereby increasing the heat dissipation area to achieve basic heat dissipation; the heat dissipation grooves etched on the surface can enhance the airflow turbulence effect and improve the convective heat dissipation efficiency; the variable cross-section design makes the root of the fins have stronger heat conduction capacity, and the top is easier to exchange heat with the air, forming a gradient heat transfer path; the heat dissipation serrations on the edge further expand the heat dissipation area, and together with the heat dissipation coating sprayed on the surface, enhance the heat radiation capacity. The synergy of multiple structures significantly improves the heat dissipation efficiency and can meet the continuous heat dissipation needs of high-power equipment. Attached Figure Description

[0019] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0021] like Figure 1 and Figure 2 As shown, a specific embodiment of this utility model provides a finned heat dissipation structure for an explosion-proof electric actuator housing. It employs a novel thermally conductive and insulating composite structure and a gradient finned heat dissipation design to achieve efficient heat dissipation of the internal heat-generating structure of the electric actuator. Specifically, it includes an explosion-proof housing 100, a heat-conducting mechanism, and a heat dissipation mechanism. The heat-conducting mechanism includes heat-conducting columns 200 uniformly arranged on the inner wall of the explosion-proof housing 100. Each heat-conducting column 200 includes an insulating section 210 in contact with the inner wall of the explosion-proof housing 100, and the insulating section 210 is connected to a heat-conducting section 220 in contact with the heat-generating structure. The heat dissipation mechanism includes heat dissipation fins 300 uniformly arranged on the outer surface of the explosion-proof housing 100, and the surface of the heat dissipation fins 300 is etched with heat dissipation grooves 310.

[0022] like Figure 1 and Figure 2As shown, through the above configuration, the heat-conducting mechanism inside the explosion-proof housing 100 in this embodiment is used to conduct the heat generated by the heating structure to the outside of the explosion-proof housing 100. The heat-conducting section 220 of the heat-conducting column 200 is in direct contact with the heating structure, which is conducive to efficient heat conduction. At the same time, the insulating section 210 is in contact with the inner wall of the explosion-proof housing 100, which conducts heat to the surface of the explosion-proof housing 100 on the one hand, and ensures the insulation effect on the other hand. After the heat is conducted to the surface of the explosion-proof housing 100, it is dissipated through the heat dissipation mechanism. The heat dissipation fins 300 are evenly arranged on the surface of the explosion-proof housing 100 to achieve direct heat dissipation. The heat dissipation grooves 310 arranged on the surface of the heat dissipation fins 300 are used to enhance turbulent heat dissipation and improve the heat dissipation effect, which is suitable for high-power sealed explosion-proof equipment.

[0023] like Figure 1 As shown, in the heat-conducting column 200 provided in this embodiment, the insulating section 210 is a ceramic column, and the heat-conducting section 220 is a copper column. The insulating section 210 uses a ceramic column to contact the inner wall of the explosion-proof housing 100, ensuring electrical insulation during heat conduction and avoiding the risk of leakage or electric sparks; the heat-conducting section 220 uses a copper column to directly contact the heating structure, utilizing the high thermal conductivity of copper to quickly absorb heat and conduct it to the insulating section 210, achieving the dual functions of efficient heat conduction and safe insulation.

[0024] like Figure 2 As shown, for the heat dissipation fin 300 structure, in practical applications, the bottom thickness of the heat dissipation fin 300 is greater than the top thickness, forming a variable cross-section fin. The variable cross-section design gives the root of the fin stronger heat conduction capacity, and the top is easier to exchange heat with the air, forming a gradient heat transfer path; the surface of the heat dissipation fin 300 is coated with a heat dissipation coating, which, together with the surface coating, enhances the heat radiation capacity; the edges of the heat dissipation fin 300 are provided with heat dissipation serrations 320; the heat dissipation serrations 320 on the edges (preferred solution) further expand the heat dissipation area. In practical applications, the bottom thickness of the heat dissipation fin 300 is 2mm, and the top thickness is 0.5mm. During installation, it is fixed to the outer wall of the housing by rivetless riveting to ensure the structural strength of the explosion-proof housing 100. During etching, the width of the heat dissipation groove 310 is 0.1mm and the depth is 0.2mm.

[0025] In production applications, the explosion-proof housing 100 is extruded using an aluminum and graphene composite material. The excellent thermal conductivity of aluminum combined with the high thermal conductivity enhancement effect of graphene (graphene mass fraction 3-7%) significantly improves the overall thermal conductivity of the housing, ensuring rapid heat transfer from the inner wall to the outer surface heat dissipation fins 300. Simultaneously, the composite material possesses high structural strength, meeting the pressure and impact resistance requirements of the explosion-proof housing 100, ensuring heat dissipation performance without compromising the explosion-proof sealing integrity.

[0026] In summary, the heat dissipation structure provided in this embodiment, through its innovative thermally conductive and insulating composite structure, gradient fin heat dissipation design, and material optimization, achieves efficient heat dissipation while ensuring explosion-proof sealing and insulation safety. It effectively solves the problems of low heat dissipation efficiency and insufficient safety of traditional explosion-proof equipment, and provides a reliable guarantee for the stable operation of high-power explosion-proof equipment in high-risk environments.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
