Description
Technical Field
[0001] This utility model relates to the field of radiator technology, and in particular to a multi-channel liquid-cooled radiator. Background Technology
[0002] A locomotive is a self-propelled vehicle that pulls or pushes railway vehicles without carrying its own commercial load; commonly known as a train engine, it is the most energy-efficient land transport vehicle in terms of fuel consumption per ton-kilometer. Composite cooling towers, engine room fans, main transformer radiators, and traction motor fan filters play crucial roles in the normal operation of a locomotive. To ensure proper heat dissipation for all components and prevent overheating-related malfunctions, liquid-cooled radiators are typically used.
[0003] A search revealed Chinese Patent Publication No. CN207053974U, which discloses a radiator specifically for electric locomotives. The radiator includes a metal heat sink block. A central heat sink fin is positioned at the center of the front surface of the metal heat sink block, and bolt protection rings are located on both sides of the front surface near the central heat sink fin. Fixing bolts are installed inside the bolt protection rings on the metal heat sink block. A connecting gasket is provided on the rear surface of the metal heat sink block. Radiator sides are located at both the upper and lower ends of the metal heat sink block. Horizontal heat sink fins are located on the front surface of each radiator side, and vertical heat sink fins are located on the rear surface of the radiator side. A metal heat dissipation dustproof mesh is fixed to both sides with bolts and connected to the radiator with thermally conductive adhesive, facilitating the transfer of heat from the heat sink block to the dustproof mesh, thus providing auxiliary heat dissipation for the radiator and indirectly improving heat dissipation efficiency. Simultaneously, the dustproof mesh effectively reduces dust on the radiator.
[0004] Although the heat sink in the above patent can prevent dust, it has few heat dissipation paths and poor heat dissipation effect. The contact area between the coolant and the heat-conducting structure is still limited, and the cooling effect is difficult to improve due to structural limitations. Therefore, it is necessary to design a multi-channel liquid-cooled heat sink to solve the above problems. Utility Model Content
[0005] The main objective of this invention is to provide a multi-channel liquid-cooled heat sink that can effectively solve the problems in the background art.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A multi-channel liquid-cooled radiator includes a heat-conducting base, a cover plate movably connected to the front of the heat-conducting base, heat dissipation fins fixedly connected to the center of the front of the cover plate, and a liquid inlet pipe movably connected to the top of the inner side of the heat-conducting base and the cover plate; a distribution pipe fixedly connected to one end of the liquid inlet pipe, a first cooling pipe fixedly connected to one end of the distribution pipe, a second cooling pipe fixedly connected to the other end of the distribution pipe, a connecting pipe fixedly connected to one end of both the first and second cooling pipes, and a return pipe fixedly connected to the outer surface of the connecting pipe.
[0008] In order to facilitate the clamping of the cooling pipe, as a multi-channel liquid cooling radiator of this utility model, a first pipe clamp is fixedly connected to the inner side of the heat conduction seat near the first cooling pipe, and a second pipe clamp is fixedly connected to the inner side of the cover plate near the second cooling pipe.
[0009] In order to enhance the sealing effect of the connection between the liquid inlet pipe and the return pipe, as a multi-channel liquid cooling radiator of this utility model, semi-circular grooves are provided on the top and bottom of the outer surface of the heat conduction seat and the cover plate, and a sealing ring is fitted on one side of the outer surface of the liquid inlet pipe and the return pipe.
[0010] In order to enhance the sealing effect of the cover plate, a sealing gasket is fixedly connected to the inner side of the heat conduction seat as a multi-channel liquid cooling radiator of this utility model.
[0011] To facilitate the connection of the cover plate, in this multi-channel liquid cooling radiator, limiting plates are fixedly connected to both sides of the outer surface of the heat-conducting base. A connecting rod is fixedly connected to the outer surface of the cover plate near the limiting plate. A first spring is fixedly connected to both sides of the inner side of the connecting rod. A limiting rod is fixedly connected to one end of the first spring. The limiting rod is movably connected to the limiting plate.
[0012] In order to prevent the cover plate from shaking up and down, as a multi-channel liquid cooling radiator of this utility model, a locking tongue is fixedly connected to the middle of the outer surface of the cover plate, and a housing is fixedly connected to the outer surface of the heat conduction seat near the locking tongue. A locking hole is opened on one side of the outer surface of the housing.
[0013] To enhance the connection strength of the cover plate, as a multi-channel liquid cooling radiator of this utility model, a pull rod is slidably connected to the middle of the inner side of the housing, a gasket is fixedly connected to one side of the outer surface of the pull rod, a second spring is sleeved on the outer surface of the pull rod near the gasket, and a limit hole is opened on the outer surface of the locking tongue near the pull rod.
[0014] In order to facilitate the installation of the heat-conducting base, as a multi-channel liquid cooling radiator of this utility model, the upper and lower surfaces of the heat-conducting base are fixedly connected with mounting plates, and mounting holes are opened on both sides of the outer surface of the mounting plates.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. In this utility model, by setting up a distribution pipe, a first cooling pipe, a second cooling pipe, and a connecting pipe, the distribution pipe allows the coolant to flow into the interior of the first and second cooling pipes respectively, and finally returns to the coolant storage area through the connecting pipe and the return pipe, forming a reflux. This allows the coolant to flow continuously for cooling and heat dissipation, improving cooling efficiency. The first and second cooling pipes are arranged alternately on both sides, evenly distributed throughout the interior of the radiator, greatly increasing the coverage area and making heat dissipation more uniform. This achieves multi-channel distribution of the coolant, improving its liquid cooling effect. At the same time, replacing the traditional coolant flow channel with a hollow pipe can prevent coolant leakage inside the radiator.

In this utility model, by setting up a first spring, a limiting rod, a locking tongue, a pull rod, and a second spring, pressing the limiting rod causes it to retract into the interior of the connecting rod, placing the connecting rod on the inner side of the two sets of limiting plates. Under the elastic action of the first spring, the limiting rod is inserted into the interior of the limiting plate, connecting the cover plate to the heat-conducting seat, making the cover plate easy to open and close. Pulling the pull rod compresses the second spring, facilitating the insertion of the locking tongue into the lock hole. Releasing the pull rod, under the elastic action of the second spring, the washer drives the pull rod to insert into the interior of the limiting hole, fixing the locking tongue, further strengthening the connection's firmness, making the cover plate easier to open and close, simple to operate, and convenient for inspecting and maintaining internal components.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] like Figure 1-5 As shown, a multi-channel liquid-cooled radiator includes a heat-conducting base 1, a cover plate 2 movably connected to the front of the heat-conducting base 1, a heat dissipation fin 3 fixedly connected to the middle of the front of the cover plate 2, and an inlet pipe 4 movably connected to the top of the inner side of the heat-conducting base 1 and the cover plate 2; a diversion pipe 5 is fixedly connected to one end of the inlet pipe 4, a first cooling pipe 6 is fixedly connected to one end of the diversion pipe 5, a second cooling pipe 7 is fixedly connected to the other end of the diversion pipe 5, a connecting pipe 8 is fixedly connected to one end of both the first cooling pipe 6 and the second cooling pipe 7, and a return pipe 9 is fixedly connected to the outer surface of the connecting pipe 8.
[0027] In practical use, through the arrangement of heat dissipation fins 3, diversion pipes 5, first cooling pipes 6, second cooling pipes 7, and connecting pipes 8, the heat-conducting seat 1 contacts the locomotive's components that require heat dissipation, guiding the heat generated during component use. Heat dissipation fins 3 dissipate heat from inside the radiator, further enhancing the heat dissipation area and improving heat dissipation capacity. Coolant is transported through the inlet pipe 4, and the diversion pipes 5 divide the coolant, allowing it to flow into the first cooling pipe 6 and the second cooling pipe 7 respectively. Finally, it returns to the coolant storage area through the connecting pipe 8 and the return pipe 9, forming a reflux. This allows the coolant to continuously flow for cooling and heat dissipation, greatly improving cooling efficiency. The first cooling pipe 6 and the second cooling pipe 7 are arranged alternately on both sides, evenly distributed throughout the radiator, greatly increasing the coverage area and making heat dissipation more uniform. This achieves multi-channel diversion of the coolant, improving its liquid cooling effect. At the same time, replacing the traditional coolant flow channel with a hollow pipe can prevent coolant leakage inside the radiator.
[0028] In this embodiment, a first pipe clamp 10 is fixedly connected to the inner side of the heat-conducting base 1 near the first cooling pipe 6, and a second pipe clamp 11 is fixedly connected to the inner side of the cover plate 2 near the second cooling pipe 7.
[0029] In practical use, the first pipe clamp 10 and the second pipe clamp 11 are provided in multiples, which can clamp and fix the first cooling pipe 6 and the second cooling pipe 7, increasing the stability of use and the robustness of the structure, making the installation and disassembly of the first cooling pipe 6 and the second cooling pipe 7 more convenient, and facilitating replacement and maintenance.
[0030] In this embodiment, semi-circular grooves 12 are provided on the top and bottom of the outer surfaces of the heat-conducting base 1 and the cover plate 2, and sealing rings 13 are fitted on one side of the outer surfaces of the liquid inlet pipe 4 and the return pipe 9.
[0031] In practical use, by setting the sealing ring 13, two sets of sealing rings 13 are respectively fitted on the outer surface of the liquid inlet pipe 4 and the return pipe 9. When the liquid inlet pipe 4 and the return pipe 9 are installed, the sealing ring 13 is snapped into the inside of the semi-circular groove 12, which strengthens the sealing of the connection between the liquid inlet pipe 4 and the return pipe 9, reduces wear, and extends service life.
[0032] In this embodiment, a sealing gasket 14 is fixedly connected to the inner side of the heat-conducting base 1.
[0033] In practical use, the sealing gasket 14 is fixed to the inner side of the heat-conducting base 1. When the cover plate 2 is closed, the sealing gasket 14 strengthens the sealing at the connection between the heat-conducting base 1 and the inner side of the cover plate 2, preventing the entry of external dust and enhancing the sealing effect.
[0034] In this embodiment, limiting plates 15 are fixedly connected to both sides of the outer surface of the heat-conducting base 1, and a connecting rod 16 is fixedly connected to the side of the outer surface of the cover plate 2 near the limiting plate 15. A first spring 17 is fixedly connected to both sides of the inner side of the connecting rod 16, and a limiting rod 18 is fixedly connected to one end of the first spring 17. The limiting rod 18 is movably connected to the limiting plate 15.
[0035] In practical use, by setting the first spring 17 and the limiting rod 18, pressing the limiting rod 18 causes it to retract into the inside of the connecting rod 16. Then, the connecting rod 16 is placed on the inner side of the two sets of limiting plates 15 to prevent the cover plate 2 from moving up and down. Then, under the elastic action of the first spring 17, the limiting rod 18 is inserted into the inside of the limiting plate 15, connecting the cover plate 2 to the heat-conducting seat 1. This makes it easy to open and close the cover plate 2, making it convenient to open the cover plate 2 to maintain the internal structure. At the same time, it makes it easier to install and disassemble the cover plate 2, making it easier to replace when damaged, thus saving costs.
[0036] In this embodiment, a locking tongue 19 is fixedly connected to the middle of the outer surface of the cover plate 2, and a housing 20 is fixedly connected to the outer surface of the heat conduction seat 1 near the locking tongue 19. A locking hole 21 is provided on one side of the outer surface of the housing 20.
[0037] In practical use, by setting the locking tongue 19, when the cover plate 2 is closed, the locking tongue 19 is inserted into the inside of the housing 20 through the locking hole 21 to prevent the cover plate 2 from shaking up and down, thus playing a limiting role.
[0038] In this embodiment, a pull rod 22 is slidably connected to the middle of the inner side of the housing 20, a gasket 23 is fixedly connected to one side of the outer surface of the pull rod 22, a second spring 24 is sleeved on the outer surface of the pull rod 22 near the gasket 23, and a limit hole 25 is opened on the outer surface of the locking tongue 19 near the pull rod 22.
[0039] In practical use, by setting up the pull rod 22 and the second spring 24, pulling the pull rod 22 compresses the second spring 24, making it easier for the latch 19 to be inserted into the lock hole 21. When the pull rod 22 is released, under the elastic action of the second spring 24, the washer 23 drives the pull rod 22 to be inserted into the limiting hole 25, fixing the latch 19 and preventing it from moving back and forth. This further strengthens the connection and makes the opening and closing of the cover plate 2 more convenient, simple to operate, and easy to inspect and maintain the internal components.
[0040] In this embodiment, mounting plates 26 are fixedly connected to both the upper and lower surfaces of the heat-conducting base 1, and mounting holes 27 are provided on both sides of the outer surface of the mounting plate 26.
[0041] In practical use, the mounting holes 27 are set on both sides of the outer surface of the mounting plate 26 and are used in conjunction with external bolts to facilitate the installation and fixing of the radiator.
[0042] Working principle: In use, pressing the limiting rod 18 places the connecting rod 16 on the inner side of the two sets of limiting plates 15. Under the elastic action of the first spring 17, the limiting rod 18 is inserted into the inside of the limiting plate 15, connecting the cover plate 2 to the heat-conducting seat 1. The first cooling pipe 6 and the second cooling pipe 7 are clamped and fixed by the first pipe clamp 10 and the second pipe clamp 11. The two sets of sealing rings 13 are respectively sleeved on the outer surface of the liquid inlet pipe 4 and the return pipe 9. When the cover plate 2 is closed, the sealing rings 13 are engaged inside the semi-circular groove 12, strengthening the sealing of the connection between the liquid inlet pipe 4 and the return pipe 9. The sealing gasket 14 strengthens the sealing of the connection between the heat-conducting seat 1 and the inner side of the cover plate 2. Pulling the pull rod 22 compresses the second spring 24, making it easier for the locking tongue 19 to be inserted into the lock hole 21. Releasing the pull rod 22... Under the elastic action of the second spring 24, the washer 23 drives the pull rod 22 to be inserted into the inside of the limiting hole 25 to fix the locking tongue 19. The heat conduction seat 1 contacts the locomotive's heat dissipation components and guides the heat generated during the use of the components. The heat dissipation fins 3 dissipate the heat inside the radiator. The liquid inlet pipe 4 transports the coolant. The diversion pipe 5 allows the coolant to flow into the first cooling pipe 6 and the second cooling pipe 7 respectively. Finally, it returns to the coolant storage area through the connecting pipe 8 and the return pipe 9, forming a reflux. This allows the coolant to flow continuously for cooling and heat dissipation. The first cooling pipe 6 and the second cooling pipe 7 are arranged alternately on both sides and are evenly distributed throughout the radiator, greatly increasing the coverage area and making the heat dissipation more uniform. This achieves multi-channel diversion of the coolant and improves its liquid cooling effect.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
