[0002] In some material sorting scenarios, such as the sorting of ores and coal, high-power equipment is often used. For explosion-proof equipment used in mining, the power is relatively large, and the heat dissipation requirements are high. Due to the thick walls of the explosion-proof enclosure, heat exchange between the inside and outside of the enclosure is difficult, which may prevent the high-power equipment from dissipating heat in time, leading to equipment failure and affecting sorting efficiency and output.

[0003] To overcome the problems existing in the related technologies, an exemplary embodiment of the present disclosure provides a heat dissipation device for use in equipment requiring heat dissipation. The heat dissipation device includes: a housing for housing the equipment; a heat dissipation plate assembly installed on the side wall of the housing and having a first flow channel formed inside; an auxiliary heat dissipation mechanism disposed on the surface of the equipment and communicating with the first flow channel for exchanging heat with the surface of the equipment through liquid flow; and heat dissipation fins disposed on the heat dissipation plate assembly facing the outside of the housing for receiving heat transferred by the heat dissipation plate assembly and dissipating the heat.

[0004] In some embodiments, the heat dissipation device further includes: a water-cooled cover, which is disposed on the outside of the heat dissipation fins, and a liquid inlet is provided on the water-cooled cover for introducing liquid to dissipate the heat transferred to the heat dissipation fins.

[0005] In some embodiments, the heat dissipation device further includes a first sealing gasket disposed between the water cooling cover and the heat dissipation plate assembly for achieving a sealed connection.

[0006] In some embodiments, the heat sink assembly includes: a heat sink with a plate-like structure and an outer side connected to heat sink fins; one or more flow guides disposed on the inner surface of the heat sink; a pressure plate connected to the inner side of the flow guides and forming a first flow channel between the pressure plate and the heat sink; and a heat sink flange circumferentially disposed around the periphery of the heat sink and fixedly connected to the housing.

[0007] In some embodiments, the heat sink assembly further includes a second sealing gasket disposed between the guide plate and the pressure plate for achieving a sealed connection.

[0008] In some embodiments, the flow guide includes: a flow guide frame fixed to the inner edge of the heat sink; one or more first flow guides, one end of which is connected to a first side of the flow guide frame and the other end of which extends to a second side of the flow guide frame, wherein the second side is opposite to the first side; one or more second flow guides, one end of which is connected to the second side and the other end of which extends toward the first side and is arranged parallel to and spaced apart from the first flow guides, wherein the first flow guides and the second flow guides cooperate with each other to form a bent first flow channel.

[0009] In some embodiments, the heat sink assembly further includes: a first liquid inlet disposed at the lower part of the pressure plate, communicating with the first flow channel and the auxiliary heat dissipation mechanism; and a first liquid outlet disposed at the upper part of the pressure plate, communicating with the first flow channel and the auxiliary heat dissipation mechanism, for discharging liquid flowing through the first flow channel.

[0010] In some embodiments, the auxiliary heat dissipation mechanism has a second flow channel inside and a second liquid inlet and a second liquid outlet communicating with the second flow channel. The second liquid inlet is connected to the first liquid outlet, and the second liquid outlet is connected to the first liquid inlet, for heat exchange of the equipment.

[0011] In some embodiments, the heat dissipation device further includes: a water pump disposed inside the housing, having a third liquid inlet and a third liquid outlet, the third liquid inlet being connected to a second liquid outlet and the third liquid outlet being connected to a first liquid inlet, for driving liquid circulation.

[0012] Secondly, this disclosure also provides a sorting machine, including: a conveying device for conveying materials; an identification device for identifying the materials conveyed by the conveying device; a sorting device for sorting the materials according to the identification result of the identification device; a heat dissipation device, which includes: an X-ray transmitter and / or a switch; and a heat dissipation device as described in any of the first aspects above, for heat exchange of the equipment.

[0013] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure.

[0014] This disclosure provides a heat dissipation device that separates internal and external heat dissipation, achieving efficient and non-interfering heat dissipation. Internal heat dissipation is achieved collaboratively by an auxiliary heat dissipation mechanism and the first flow channel of the heat dissipation plate assembly: the auxiliary heat dissipation mechanism is directly attached to the equipment surface and communicates with the first flow channel inside the chamber. The liquid circulates within the flow channel, absorbing the heat generated by the equipment at close range, forming a closed loop within the chamber and preventing contact with the outside. External heat dissipation is achieved by the heat dissipation fins on the outer side of the heat dissipation plate assembly: after the internal flow channel transfers heat to the heat dissipation plate assembly, the heat is conducted to the heat dissipation fins on the outer side of the chamber, dissipating the heat to the outside without affecting the internal heat dissipation operation. This separate heat dissipation device allows heat to be transferred from inside the chamber to the outside, achieving efficient heat dissipation, extending the service life of high-power equipment, improving sorting efficiency, and increasing sorting output.

[0021] In some scenarios, such as the sorting of materials like coal and ore, high-power equipment is frequently used. For explosion-proof mining equipment, which contains high-power components with stringent heat dissipation requirements, the thick walls of the explosion-proof enclosure, typically made of carbon steel and coated with arc-resistant paint, make heat exchange between the inside and outside of the enclosure difficult. Some related technologies reduce the power of internal components and place heat-generating devices close to the inner wall of the enclosure, using thermally conductive adhesive to achieve heat dissipation through conduction. However, this method significantly limits the power of the internal components. Other related technologies use water pipes to circulate between the enclosure and an external cooler for heat dissipation. However, this method is only applicable to explosion-proof equipment meeting Class II environmental standards. For coal mine safety equipment, national standards do not allow for circulating water channels between the inside and outside of the enclosure, making heat dissipation a major challenge.

[0022] To overcome the problems existing in related technologies, an exemplary embodiment of this disclosure provides a heat dissipation device 100, such as... Figure 1 As shown, this technology can be applied to high-power equipment requiring heat dissipation and is suitable for explosion-proof coal mine safety equipment, achieving efficient heat dissipation while meeting coal mine safety requirements. The heat dissipation equipment 200 can be an X-ray transmitter or switch in a sorting machine. The X-ray transmitter can be used in material sorting scenarios to emit X-rays for material identification. The switch can be used to connect to and control coal mining machines, scraper conveyors, etc., in material sorting scenarios.

[0023] Heat dissipation device 100, such as Figure 1 As shown, it may include: a housing 110, a heat sink assembly 120, an auxiliary heat dissipation mechanism 130, and heat dissipation fins 140.

[0024] Box 110, such as Figure 1 , Figure 2 As shown, the enclosure 110 is used to house the equipment 200 requiring heat dissipation. The enclosure itself can be a rectangular parallelepiped with a rigid frame, forming a sealed cavity internally, or one side can be fixed to the bracket of the sorting machine to form a relatively enclosed structure. The wall thickness is set according to the explosion-proof rating, and can be 8-15 mm. The interior of the enclosure 110 may contain support frames for fixing components such as the equipment 200. One side wall of the enclosure 110 may have a through groove to form a mounting position for the heat dissipation plate assembly 120, and be fixedly connected to the heat dissipation plate assembly 120, such as by bolts.

[0025] Heat sink assembly 120, such as Figure 1 , Figure 2As shown, it is installed on the side wall of the enclosure 110. The heat sink assembly 120 can be a rectangular thick plate structure, with dimensions consistent with the mounting position on the side wall of the enclosure 110, and is fixed to one side of the enclosure 110 by bolts or the like. The heat sink assembly 120 can be connected to the enclosure 110 via a flange, and the flange surfaces of the two form an explosion-proof mating surface, ensuring structural stability while achieving close contact between the heat sink assembly 120 and the side wall of the enclosure 110, aiding in heat conduction. The heat sink assembly 120 can be made of copper, which has high thermal conductivity.

[0026] like Figure 3 As shown, a first flow channel 121 for fluid flow can be formed inside the heat sink assembly 120. The heat sink assembly 120 can have a groove to form the first flow channel 121, or it can be formed by a guide vane and pressure plates on both sides enclosing the first flow channel 121. The flow channel 121 can be tortuous, such as U-shaped, S-shaped, or serpentine, to ensure sufficient contact between the liquid and the heat sink assembly 120 for efficient heat exchange. Heat dissipation fins 140 can be connected to the outside of the heat sink assembly 120, transferring the heat flowing through the first flow channel 121 to the heat dissipation fins 140, which then dissipate the heat.

[0027] Auxiliary heat dissipation mechanism 130, such as Figure 1 , Figure 2 As shown, it is used to be installed on the surface of device 200. The auxiliary heat dissipation mechanism 130 can be in the form of a long tubular structure, which can be directly attached to the heat-generating surface of device 200. The heat generated by device 200 is carried away by the flow of liquid, which can achieve efficient heat dissipation.

[0028] The auxiliary heat dissipation mechanism 130 can be connected to the first flow channel 121 for heat exchange with the surface of the equipment 200 via liquid flow. The auxiliary heat dissipation mechanism 130 can be internally connected to the first flow channel 121 to achieve a closed liquid circulation. The liquid directly absorbs heat from the surface of the equipment 200 through its flow and can transfer the heat to the heat dissipation plate assembly 120. The heat dissipation plate assembly 120 then transfers the heat to the outer heat dissipation fins 140 for heat exchange. The liquid circulates only within the housing 110, without any openings connecting it to external components for heat exchange, meeting national standards for coal mine safety equipment. Therefore, the heat from the high-power equipment 200 inside the housing 110 can be transferred through the first flow channel to the heat dissipation fins 140 outside the heat dissipation plate assembly 120, where the heat dissipation fins 140 then dissipate the heat. The liquid circulation inside the housing 110 and the heat dissipation outside the housing 110 are separated and independently configured for efficient heat dissipation.

[0029] Heat sink fins 140, such as Figure 1 , Figure 3As shown, the heat sink assembly 120 can be positioned on the outside of the housing 110 to receive heat transferred from the heat sink assembly 120 and dissipate it. The heat sink fins 140 can be parallel thin plates, generally toothed or columnar, and multiple fins can form multiple heat conduction paths, ensuring that gas or liquid can flow through each fin of the heat sink fins 140, thus increasing the heat dissipation area and avoiding localized heat exchange dead zones. The heat sink fins 140 are located on the outside of the heat sink assembly 120 and extend outwards from the housing 110, and can be integrally formed with the heat sink assembly 120 or fixed by welding. The heat sink fins 140 can receive heat transferred from the auxiliary heat dissipation mechanism 130 to the heat sink assembly 120. The heat sink fins 140 can exchange heat through convection with the outside air or by introducing cooling liquid. The heat sink fins 140 can be made of materials such as copper, which have good thermal conductivity and high heat exchange efficiency.

[0030] Heat dissipation fins 140 are disposed on the outer side of the heat dissipation plate assembly 120 away from the housing 110, indirectly receiving heat transferred from the auxiliary heat dissipation mechanism 130 to the first flow channel 121 inside the heat dissipation plate assembly 120. The hot liquid reaching the first flow channel 121 can fully transfer heat to the scattering fins 140 on its back through the tortuous first flow channel 121, resulting in heat exchange. After heat exchange, the liquid temperature decreases, flowing out from the outlet of the first flow channel 121 and towards the auxiliary heat dissipation mechanism 130, where it once again receives heat from the device 200 for the next cycle. The circulation of the liquid inside the housing 110 and the dissipation of heat outside the housing 110 are independent and separated from each other, achieving efficient heat dissipation.

[0031] In some embodiments, the heat generated by the equipment 200 inside the enclosure 110, such as an X-ray transmitter or a switch, during operation is first absorbed by an auxiliary heat dissipation mechanism 130 that adheres to its heat-generating surface. The internal piping of the auxiliary heat dissipation mechanism 130 is connected to the first flow channel 121 of the heat sink assembly 120, forming a closed liquid loop that circulates only within the enclosure 110. As the liquid flows through the loop, it directly absorbs heat from the surface of the equipment 200. The heat-carrying liquid then flows into the first flow channel 121 of the heat sink assembly 120, making full contact with the copper heat sink and efficiently transferring heat to the heat sink assembly 120. The heat is then transferred from the heat sink assembly 120 to the heat dissipation fins 140 on its outer side. By increasing the contact area with the outside, the heat is dissipated to the outside of the enclosure 110 via air convection or by introducing cooling liquid, completing the entire heat exchange process. Throughout the entire process, the liquid circulates only within the enclosure 110 without any openings connecting to the outside, ensuring both efficient heat exchange and compliance with coal mine safety explosion-proof standards.

[0032] In this embodiment, efficient and stable heat dissipation of the high-power device 200 inside the housing 110 is achieved by setting up a heat dissipation device 100. The internal and external heat dissipation are separated to achieve efficient and non-interfering heat dissipation. Inside the housing 110, a closed liquid circulation is formed by the first flow channel 121 of the heat dissipation plate assembly 120 and the auxiliary heat dissipation mechanism 130. The auxiliary heat dissipation mechanism 130 is attached to the heating surface of the high-power device 200, transferring heat through the first flow channel 121 to the heat dissipation fins 140 on the outside of the housing 110, without any external openings for heat exchange. External heat dissipation is accomplished by the heat dissipation fins 140 on the outer side of the heat dissipation plate assembly 120: after the internal flow channel transfers heat to the heat dissipation plate assembly 120, the heat is conducted to the heat dissipation fins 140 on the outer side of the housing 110, dissipating the heat to the outside without affecting the internal heat dissipation operation of the housing 110. The separate arrangement of the heat dissipation device 100 enables the heat inside the housing 110 to be transferred to the outside of the housing 110, achieving efficient heat dissipation and meeting the heat dissipation requirements of high-power devices. It can effectively control the temperature rise of high-power equipment 200, with high heat exchange efficiency and good heat dissipation effect. It is suitable for environments such as mines and dust, ensuring long-term stable operation and extending the life of equipment 200.

[0033] In some embodiments, such as Figure 1 , Figure 2 As shown, the heat dissipation device 100 may further include: a water-cooling cover 150, which covers the outside of the heat dissipation fins 140. The water-cooling cover 150 has liquid inlets for introducing liquid to dissipate heat transferred to the heat dissipation fins 140. The water-cooling cover 150 may have a rectangular cavity structure, with dimensions matching those of the heat dissipation fins 140, but slightly larger than the overall outline of the heat dissipation fins 140. It can be fixed to the outer surface of the heat dissipation plate assembly 120 using screws or the like, and is fixedly connected around the outer periphery of the heat dissipation fins 140. Figure 1 , Figure 2 As shown, a relatively closed fluid cavity is formed between the water-cooled cover 150 and the heat sink assembly 120 for fluid inflow and outflow. Two liquid inlets, an inlet 151 and an outlet 152, can be provided on the cover of the water-cooled cover 150, connecting to an external cooling system to form an independent liquid circulation outside the housing 110. Low-temperature cooling liquid can be introduced into the water-cooled cover 150 through the inlet, where it undergoes convective heat exchange with the heat sink fins 140, and the liquid is discharged through the outlet, quickly removing the heat absorbed by the heat sink fins 140. This heat is transferred from the heat sink assembly 120 to the equipment inside the housing 110, achieving heat circulation outside the housing 110. Combined with the internal circulation of the housing 110, the two are independent and provide rapid heat dissipation. The water-cooled cover 150 can be made of stainless steel or other materials, possessing high hardness and strength, extending the service life of the components.

[0034] In this embodiment, a water-cooled cover 150 is installed, and the independent liquid cooling circulation outside the housing 110 works in conjunction with the internal heat dissipation system of the housing 110 to improve heat dissipation efficiency. A rectangular cavity completely covers the heat dissipation fins 140, which are connected to an external cooling system through inlet and outlet ports. Low-temperature liquid is introduced and convects with the fins, quickly removing heat absorbed by the fins from the equipment inside the housing 110. Simultaneously, the external circulation is completely isolated from the internal liquid circuit, preserving the airtightness of the housing 110. Combined with a stable and sealed design, this strictly meets the explosion-proof requirements for coal mine safety. Furthermore, it ensures the continuous and stable operation of high-power equipment such as X-ray transmitters and switches in the high-temperature, dusty mining environment, reducing the risk of shutdowns due to overheating.

[0035] In some embodiments, such as Figure 1 As shown, the heat dissipation device 100 may further include a first sealing gasket 160, disposed between the water-cooling cover 150 and the heat sink assembly 120, for achieving a sealed connection. The first sealing gasket 160 is an annular or rectangular sheet structure that matches the contour of the contact surfaces of the water-cooling cover 150 and the heat sink assembly 120, sandwiched between the contact surfaces of the two, and pressed together with the fixing screws of the water-cooling cover 150 to form a tight sealing interface. The first sealing gasket 160 can be made of rubber, which has good elasticity and anti-aging properties, and can be adapted to the mining environment. The first sealing gasket 160 in this embodiment has strong adaptability and high sealing reliability, which can prevent the cooling liquid inside the water-cooling cover 150 from leaking from the contact gap, ensure the airtightness of the external liquid cooling circulation of the housing 110, avoid the reduction of heat dissipation effect due to liquid leakage, reduce maintenance frequency, and ensure the long-term stable operation of the entire heat dissipation device 100.

[0036] In some embodiments, such as Figure 3 As shown, the heat sink assembly 120 may include: a heat sink 122, a guide vane 123, a pressure plate 124, and a heat dissipation flange 125.

[0037] Heat sink 122, such as Figure 3 As shown, it can be in the form of a plate, with the outer side connected to the heat dissipation fins 140. The heat dissipation plate 122 can be a flat plate structure, made of high thermal conductivity copper, and connected to the heat dissipation fins 140 on the outer side. It can be integrally formed, welded, or bolted. The inner surface can be processed to fit the flow guide fins 123, which can serve as the core carrier for heat conduction, and can efficiently transfer the liquid heat in the first flow channel 121 to the heat dissipation fins 140.

[0038] One or more guide vanes 123, such as Figure 3 As shown, it can be disposed on the inner surface of the heat sink 122. The guide vane 123 can be one or more thin plates, the shape of which can be strip or arc, etc., and can be fixed to the inner side of the heat sink 122. It can be arranged in an S-shape, U-shape or serpentine shape, and form a first channel 121 for liquid flow through the interval distribution.

[0039] Pressure plate 124, such as Figure 3 As shown, it can be connected to the inner side of the guide plate 123, forming a first flow channel 121 between it and the heat sink 122. The pressure plate 124 can be a flat plate with the same size as the heat sink 122, covering the inner side of the guide plate 123 near the housing and rigidly connected to the guide plate 123. It can be fastened with bolts, etc. Together with the heat sink 122 and the guide plate 123, it forms a complete first flow channel 121, guiding the liquid to fully contact the heat sink 122 and improving the heat exchange efficiency.

[0040] Heat dissipation flange 125, such as Figure 3 As shown, the heat dissipation flange 125 can be arranged around the periphery of the heat dissipation plate 122 and fixedly connected to the housing 110. The heat dissipation flange 125 can be an annular structure arranged around the periphery of the heat dissipation plate 122, which can be integrally formed or welded to the heat dissipation plate 122. The surface is machined with evenly distributed bolt holes, and it is bolted to the mounting position on the side wall of the housing 110. The flange face and the housing flange form an explosion-proof joint surface, which not only realizes the stable fixation of the heat dissipation plate assembly 120 to the housing 110, but also meets the explosion-proof gap requirements for coal mine safety, while enhancing the structural strength of the edge of the heat dissipation plate 122 and preventing the connection from loosening due to vibration.

[0041] In this embodiment, the heat sink 122, guide vanes 123, pressure plate 124, and heat dissipation flange 125 work together to provide reliable heat conduction and safe connection for the mining heat dissipation device 100. The copper heat sink 122 combines high thermal conductivity with structural strength. Its outer side is tightly connected to the heat dissipation fins 140, allowing for rapid transfer of liquid heat from the first flow channel 121 to the fins 140. The inner guide vanes 123, together with the pressure plate 124, form a complete flow channel, extending the liquid flow path and ensuring full contact between the liquid and the heat sink, significantly improving heat exchange efficiency and preventing localized heat accumulation. The heat dissipation flange 125 is integrated with the heat sink 122 and rigidly connected to the housing 110 via bolts. The flange surface forms an explosion-proof joint surface, meeting the explosion-proof gap requirements for coal mine safety and enhancing the edge strength of the component to prevent loosening due to mine vibration. The overall structure ensures efficient heat transfer from the enclosure 110 to the heat dissipation fins 140, strictly adheres to mining explosion-proof standards, and has strong environmental adaptability, ensuring long-term stable operation of the heat dissipation system under mining conditions, and providing support for reliable heat dissipation of high-power equipment inside the enclosure 110.

[0042] In some embodiments, such as Figure 3As shown, the heat sink assembly 120 may further include a second sealing gasket 126, which can be disposed between the guide vane 123 and the pressure plate 124 to achieve a sealed connection. The second sealing gasket 126 has a strip-shaped or annular sheet structure consistent with the top surface contour of the guide vane 123, and its shape can be set according to the arrangement path of the guide vane 123. It covers the contact gap between the guide vane 123 and the pressure plate 124 and is sandwiched between the two. The material of the second sealing gasket 126 can be rubber, which has both good elasticity and compression resilience. The second sealing gasket 126 can prevent the liquid in the first flow channel 121 from leaking from the connection gap between the guide vane 123 and the pressure plate 124, maintain the airtightness of the flow channel, ensure sufficient heat exchange between the liquid and the heat sink 122, eliminate the risk of leakage, meet coal mine safety standards, reduce the decrease in heat dissipation efficiency caused by liquid loss, reduce maintenance frequency, and ensure the long-term stable operation of the heat sink assembly 120.

[0043] In some embodiments, such as Figure 3 As shown, the guide vane 123 may include: a guide frame 1231, a first guide vane 1232, and a second guide vane 1233.

[0044] The flow guide frame 1231 can be fixed to the inner edge of the heat sink 122. The flow guide frame 1231 has an annular or rectangular frame structure that matches the contour of the inner edge of the heat sink 122. It is fastened to the inner edge of the heat sink 122 by welding or bolting, forming both the outer perimeter boundary of the flow channel and providing a mounting base for the first flow guide 1232 and the second flow guide 1233. It can fix the position of the flow guides and seal the edge gaps, ultimately ensuring the sealing of the flow channel, preventing liquid leakage, and providing a stable foundation for the orderly arrangement of the flow guides.

[0045] One or more first guide vanes 1232 are provided, one end of which is connected to the first side of the guide frame 1231, and the other end extends to the second side of the guide frame 1231, wherein the second side is opposite to the first side. The first guide vane 1232 can be a long strip-shaped thin sheet, the length of which is slightly shorter than the distance between the first and second sides of the guide frame 1231. One end is fixed to the first side of the guide frame by welding or integral molding, and the other end extends to the second side of the guide frame without contacting the second side. The bottom is in close contact with the inner side of the heat sink 122. One or more first guide vanes 1232 can be provided, and multiple first guide vanes 1232 can be evenly spaced along the first side to guide the liquid to flow from the first side to the second side and to divert the liquid, thereby extending the contact path between the liquid and the heat sink, ensuring uniform liquid diversion, and improving heat exchange efficiency.

[0046] One or more second guide vanes 1233, one end connected to a second side, the other end extending towards a first side, and arranged parallel to and spaced apart from the first guide vane 1232. The first guide vane 1232 and the second guide vane 1233 cooperate to form a bent first flow channel 121. The number, structure, and shape of the second guide vanes 1233 may be similar to those of the first guide vane 1232. The second guide vanes, together with the first guide vane 1232, can transform the flow channel into an S-shaped, U-shaped, or serpentine bend, thereby changing the liquid flow direction. This significantly extends the liquid flow distance and residence time, ensuring full contact between the liquid and the heat sink, maximizing heat absorption efficiency, while reducing flow resistance and ensuring smooth circulation.

[0047] In this embodiment, by setting a flow guide frame 1231, a first flow guide plate 1232, and a second flow guide plate 1233, the flow guide frame 1231 is fixedly attached to the inner edge of the heat sink 122, forming a closed outer boundary of the flow channel to prevent liquid leakage from the edge, and providing a stable installation reference for the two flow guide plates to ensure long-term sealing. The first and second flow guide plates are arranged in a staggered pattern of parallel intervals and reverse extensions, transforming the flow channel into an S-shaped and U-shaped bend path, allowing it to fully contact the copper heat sink 122, significantly improving heat exchange efficiency, avoiding insufficient local heat exchange caused by direct flow, ensuring efficient heat transfer, adapting to the mining environment, and meeting the stable operation requirements of mining equipment.

[0048] In some embodiments, such as Figure 3 As shown, the heat sink assembly 120 may further include a first liquid inlet 127 and a first liquid outlet 128.

[0049] The first liquid inlet 127 can be located at the lower part of the pressure plate 124, communicating with the first flow channel 121 and the auxiliary heat dissipation mechanism 130. The first liquid inlet 127 can be a tubular interface structure, vertically arranged in the lower region of the pressure plate 124, communicating with the first flow channel 121. It is fixed to the pressure plate 124 by welding or integral molding. The other end can be connected to the outlet end of the auxiliary heat dissipation mechanism 130 through a high-pressure resistant pipeline, allowing liquid to flow in and providing a basis for efficient heat exchange.

[0050] The first liquid outlet 128 can be located on the upper part of the pressure plate 124, communicating with the first flow channel 121 and the auxiliary heat dissipation mechanism 130, and is used to discharge the liquid flowing through the first flow channel 121. The first liquid outlet 128 can be a tubular interface with the same structure as the first liquid inlet 127, located in the upper region of the pressure plate 124, diagonally or vertically distributed with the first liquid inlet 127, and communicating with the end of the first flow channel 121. It can be fixed to the pressure plate 124 by welding or integral molding, and the other end is connected to the inlet end of the auxiliary heat dissipation mechanism 130 through a pipeline. It can discharge the liquid that has flowed through the first flow channel 121 and completed heat transfer, and send it back to the auxiliary heat dissipation mechanism 130 to absorb heat again, ensuring that the liquid continues to flow in a closed loop. At the same time, it cooperates with the liquid inlet to form a complete circulation loop, ensuring the continuous transfer of heat from the equipment to the heat sink 122.

[0051] In this embodiment, a first liquid inlet 127 and a first liquid outlet 128 are provided. The first liquid inlet 127 is connected to the outlet of the auxiliary heat dissipation mechanism 130 through its lower layout, and can stably receive liquid that absorbs heat from the equipment, ensuring that the liquid carrying heat flows into the first flow channel 121. The first liquid outlet 128 is designed with a diagonal or vertical distribution at the top, and connects to the inlet of the auxiliary heat dissipation mechanism 130, so as to discharge the liquid that has completed heat exchange in a timely manner, forming a closed loop in which the auxiliary heat dissipation mechanism 130 absorbs heat into the flow channel through the first liquid inlet 127, exchanges heat in the first flow channel 121, and then returns to the auxiliary heat dissipation mechanism 130 through the first liquid outlet 128. This ensures that the liquid fills the flow channel and makes full contact with the heat dissipation plate 122, ensuring continuous heat transfer from the equipment to the heat dissipation plate 122, and guaranteeing the long-term stable operation of the mining heat dissipation system.

[0052] In some embodiments, such as Figure 2 As shown, the auxiliary heat dissipation mechanism 130 has a second flow channel 131 inside, and a second liquid inlet 132 and a second liquid outlet 133 connected to the second flow channel 131. The second liquid inlet 132 is connected to the first liquid outlet 128, and the second liquid outlet 133 is connected to the first liquid inlet 127, for heat exchange of the equipment. The auxiliary heat dissipation mechanism 130 can have a continuously penetrating second flow channel 131 inside, for example, it can be a tubular channel structure that fits against the surface of the equipment, with a second liquid inlet 132 and a second liquid outlet 133 at both ends. The auxiliary heat dissipation mechanism 130 is connected to the first liquid outlet 128 through the second liquid inlet 132 and to the first liquid inlet 127 through the second liquid outlet 133, forming a closed loop with the first flow channel 121. The circulating liquid in the second flow channel 131 directly absorbs the heat generated by the operation of the equipment, and then the hot liquid is transported to the first flow channel 121 through the second liquid outlet 133 for heat dissipation. Heat is transferred to the heat dissipation fins 140 outside the housing 110 through the first flow channel 121.

[0053] In this embodiment, the auxiliary heat dissipation mechanism 130, in contact with the second flow channel 131 on the surface of the equipment, can directly contact the heat-generating parts and quickly absorb the heat generated during equipment operation. It also connects to the first flow channel 121 through the second liquid inlet 132 and the second liquid outlet 133, forming a closed loop. The heat-absorbing liquid is then transported to the first flow channel 121 and dissipated outside the enclosure via the heat dissipation fins. This improves heat absorption efficiency, meets mining explosion-proof standards, effectively controls equipment temperature rise, ensures stable operation in the mine, and prevents malfunctions caused by overheating.

[0054] In some embodiments, such as Figure 1 , Figure 2 As shown, the heat dissipation device 100 may further include a water pump 170, which can be disposed inside the housing 110. It may have a third liquid inlet 171 and a third liquid outlet 172. The third liquid inlet 171 is connected to the second liquid outlet 133, and the third liquid outlet 172 is connected to the first liquid inlet 127, for driving liquid circulation. The water pump 170 may be configured with a miniaturized pump body structure, its size adapted to the internal space of the housing 110. It may have a third liquid inlet 171 and a third liquid outlet 172 with sealed interfaces. The water pump 170 can be connected to the second liquid outlet 133 of the auxiliary heat dissipation mechanism 130 through the third liquid inlet 171, and the third liquid outlet 172 is connected to the first liquid inlet 127 of the heat dissipation plate assembly 120, connecting the second flow channel 131 and the first flow channel 121 in series to form a power drive.

[0055] In this embodiment, the water pump 170 provides continuous power to the circulating liquid, driving the liquid to flow efficiently in a closed loop. This ensures that the liquid, after absorbing heat, is quickly delivered to the heat dissipation fins 140, avoiding localized overheating caused by liquid stagnation in the flow channel, significantly improving overall heat dissipation efficiency. At the same time, its compact design and weather-resistant materials enable it to operate stably for a long time inside the housing 110, providing core power support for the closed-loop heat exchange of the heat dissipation device 100.

[0056] Based on the same inventive concept, exemplary embodiments of this disclosure also provide a sorting machine that can be used for material sorting, such as... Figure 1 , Figure 2 As shown, it includes: such as a conveying device, an identification device, a sorting device, a heat dissipation device 200 and a heat dissipation device 100.

[0057] A conveying device is used to transport materials. The conveying device can be a conveyor belt, etc. Materials can be placed on the conveying device and transported to the identification device.

[0058] An identification device can be used to identify materials being conveyed by a conveyor system and determine the material's category. This device can be used with cameras or similar equipment to identify and classify materials.

[0059] A sorting device is used to sort materials based on the identification results of an identification device. The sorting device can be installed downstream of a belt conveyor and can separate materials according to their category, thus separating different types of materials.

[0060] The heat dissipation device 200 may include: an X-ray transmitter, a switch, etc. The heat dissipation device 200 can be a high-power device such as an X-ray transmitter or a switch in a sorting machine. The X-ray transmitter can be used in material sorting scenarios to emit X-rays for material identification. The switch can be used in material sorting scenarios to connect to and control devices such as coal mining machines and scraper conveyors.

[0061] The heat dissipation device 100 is used for heat exchange in the equipment. The heat dissipation device 100, through the coordinated use of a heat dissipation plate 122, guide vanes 123, pressure plate 124, and heat dissipation flange 125, provides reliable heat conduction and safe connection for the mining heat dissipation device 100. The copper heat dissipation plate 122 combines high thermal conductivity with structural strength. Its outer side is tightly connected to the heat dissipation fins 140, allowing for rapid transfer of liquid heat from the first flow channel 121 to the heat dissipation fins 140. The inner guide vanes 123, together with the pressure plate 124, form a complete flow channel, extending the liquid flow path and ensuring full contact between the liquid and the heat dissipation plate, significantly improving heat exchange efficiency and preventing localized heat accumulation. The heat dissipation flange 125 is integrated with the heat dissipation plate 122 and rigidly connected to the housing 110 by bolts. The flange face forms an explosion-proof joint surface, meeting the explosion-proof gap requirements for coal mine safety and enhancing the edge strength of the components to prevent loosening of the connection due to mine vibration. The overall structure ensures efficient heat transfer from the enclosure 110 to the heat dissipation fins 140, strictly adheres to mining explosion-proof standards, and has strong environmental adaptability, ensuring long-term stable operation of the heat dissipation system under mining conditions, and providing support for reliable heat dissipation of high-power equipment inside the enclosure 110.

[0062] The sorting machine in this embodiment can sort coal, ore, etc. The heat dissipation device 100 employs a separate internal and external heat dissipation design to achieve efficient and non-interfering heat dissipation. Internal heat dissipation is achieved collaboratively by the auxiliary heat dissipation mechanism 130 and the first flow channel 121 of the heat dissipation plate assembly 120: the auxiliary heat dissipation mechanism 130 is directly attached to the equipment surface and communicates with the first flow channel 121 inside the housing. The liquid circulates within the flow channel, absorbing the heat generated by the equipment at close range, forming a closed loop within the housing 110 without contact with the outside. External heat dissipation is achieved by the heat dissipation fins 140 on the outer side of the heat dissipation plate assembly 120: after the internal flow channel transfers heat to the heat dissipation plate assembly 120, the heat is conducted to the heat dissipation fins 140 on the outer side of the housing 110, dissipating the heat to the outside without affecting the internal heat dissipation operation of the housing 110. The separate design of the heat dissipation device 100 allows heat to be transferred from inside the housing 110 to the outside, achieving efficient heat dissipation and meeting the heat dissipation requirements of high-power devices.
