Description

Technical Field

[0001] This utility model relates to the technical field of radiators, specifically a high-efficiency aluminum alloy radiator with multiple cooling channels. Background Technology

[0002] The radiator of an air conditioner outdoor unit typically consists of multiple parallel metal fins or copper tubes. These fins or tubes are fixed to a frame by welding or bolting, forming a highly efficient heat exchanger. The radiator is usually made of copper or aluminum, which have good thermal conductivity and effectively improve heat dissipation efficiency. To further enhance heat dissipation efficiency, a cooling device is typically installed at the end of the radiator furthest from the electronic components. When the cooling channel comes into contact with the heat dissipation fins, cold water circulates within it, absorbing heat and carrying it away from the fins.

[0003] When existing chilled water pipes dissipate heat from fins, the inlet and outlet positions of the chilled water pipes are generally fixed. Cooling water enters the chilled water pipe from the inlet. As it flows, the pipe comes into contact with the fins and absorbs the heat from the fins. The cooled water then flows into the refrigeration system from the outlet. After cooling, the cooling water enters again from the inlet. This causes the fins near the inlet to cool down faster than the fins near the outlet, resulting in uneven heat dissipation of the metal fins. This leads to localized overheating of the metal fins and unsatisfactory heat dissipation efficiency of the radiator. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency aluminum alloy heat sink with multiple cooling channels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency aluminum alloy heat sink with multiple cooling channels includes a mounting frame and a heat dissipation assembly disposed on the mounting frame. The heat dissipation assembly includes symmetrically arranged trusses with integral fins disposed between the trusses. It also includes a cooling mechanism disposed on the mounting frame to cool down the fins. The cooling mechanism includes two interleaved first cooling pipes and second cooling pipes, which cool the area in contact with the fins. A flow adjustment component is connected between the inlet and outlet of the first cooling pipe and the second cooling pipe, respectively, and the flow adjustment component is controlled by an intermittent drive component provided on the mounting bracket. The first cooling pipe and the second cooling pipe located at both ends of the fins can intermittently change the water flow direction.

[0006] As described above, the multi-cooling-channel aluminum alloy high-efficiency radiator includes a three-way valve with three ports, two of which are respectively connected to the first cooling pipe and the second cooling pipe. It also includes a ball valve rotatably installed inside the three-way valve, wherein the ball valve is equipped with a rotating shaft that can pass through the three-way valve and is rotatably connected to the three-way valve.

[0007] The multi-cooling-channel aluminum alloy high-efficiency heat sink described above: the two rotating shafts are connected by a toothed belt.

[0008] As described above, the multi-cooling-channel aluminum alloy high-efficiency heat sink has a support frame fixedly connected to the mounting bracket, which can support the intermittent drive component.

[0009] As described above, the multi-cooling-channel aluminum alloy high-efficiency heat sink includes a grooved roller rotatably mounted on the support frame. The grooved roller is driven to rotate by a geared motor mounted on the support frame. A first sleeve is slidably arranged along the axial direction of the grooved roller. A first ball is movably arranged on the first sleeve. The first ball can slide and adapt to the groove formed by the grooved roller. The first sleeve is connected to a reciprocating deflector mounted on the support frame through a connecting hoop.

[0010] As described above, the multi-cooling-channel aluminum alloy high-efficiency heat sink includes a reciprocating deflector component comprising a drive shaft rotatably mounted on the support frame, a second sleeve being slidably sleeved along the axial direction of the drive shaft, and the second sleeve being fixed to the connecting clamp. It also includes a drive shaft rotatably mounted on the support frame, the two ends of which are connected to the drive shaft and one of the rotating shafts respectively via bevel gear sets.

[0011] As described above, the multi-cooling channel aluminum alloy high-efficiency heat sink has a limiting groove formed on the drive shaft, and a second ball bearing that is movably disposed on the inner wall of the second sleeve and slides in accordance with the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: After the fins absorb heat from the equipment, they need to be cooled. By activating the intermittent drive, the flow direction of cold water from the inlet pipe to the regulating component can be intermittently changed. This allows cold water to intermittently enter from either the first or second cooling pipe. Simultaneously, the flow direction of water from the outlet pipe to the regulating component changes synchronously, with water entering through the same inlet pipe and exiting through the same outlet pipe. These two water-cooling channels with different flow directions can intermittently cool the fins, ensuring a more uniform temperature distribution on the fins. This uniform cooling helps prevent localized overheating on the fins, thereby improving the overall heat dissipation efficiency of the heat dissipation assembly. Attached Figure Description

[0020] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0021] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0022] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0023] Please see Figures 1-6In this embodiment of the present invention, a multi-cooling-channel aluminum alloy high-efficiency heat sink includes a mounting frame 1 and a heat dissipation component 2 disposed on the mounting frame 1. The heat dissipation component 2 includes symmetrically arranged trusses 202, and integral fins 201 are disposed between the trusses 202. It also includes a cooling mechanism disposed on the mounting frame 1 to cool down the fins 201. The cooling mechanism includes two interleaved first cooling pipes 3 and second cooling pipes 4, which cool the area in contact with the fins 201. A flow adjustment component is connected between the inlet and outlet of the first cooling pipe 3 and the second cooling pipe 4, respectively, and the flow adjustment component is controlled by an intermittent drive component provided on the mounting frame 1. The first cooling pipe 3 and the second cooling pipe 4 located at both ends of the fin 201 can intermittently change the water flow direction.

[0024] In this embodiment, after the fins 201 absorb heat from the equipment, they need to be cooled down. By activating the intermittent drive, the flow direction of cold water from the inlet pipe to the regulating component can be intermittently changed, allowing cold water to intermittently enter from the first cooling pipe 3 or the second cooling pipe 4. Simultaneously, the flow direction of water from the outlet pipe to the regulating component changes synchronously, with water entering through the same inlet pipe and exiting through the same outlet pipe. These two water-cooling channels with different flow directions can intermittently cool the fins 201, ensuring a more uniform temperature distribution on the fins 201. This uniform cooling helps avoid localized overheating on the fins 201, thereby improving the overall heat dissipation efficiency of the heat dissipation assembly 2.

[0025] For further solutions to this utility model, please refer to [link / reference]. Figure 3 and Figure 4 The flow adjustment component includes a three-way valve 5, which has three ports, two of which are respectively connected to the first cooling pipe 3 and the second cooling pipe 4. It also includes a ball valve 6 rotatably installed inside the three-way valve 5, and the ball valve 6 is equipped with a rotating shaft 602 that can pass through the three-way valve 5 and is rotatably connected to the three-way valve 5.

[0026] Preferably, the two rotating shafts 602 are connected by a toothed belt 7.

[0027] The ball valve 6 has three through holes 601 in different positions, and the three through holes 601 are interconnected. One of the through holes 601 located in the water inlet channel is always connected to the water inlet channel, while the other two through holes 601 can be intermittently connected to the first cooling pipe 3 or the second cooling pipe 4. By controlling the rotation of the rotating shaft 602, when one of the through holes 601 is connected to the first cooling pipe 3, the second cooling pipe 4 is blocked, and when one of the through holes 601 is connected to the second cooling pipe 4, the first cooling pipe 3 is blocked.

[0028] Preferably, a support frame 14 is fixedly connected to the mounting frame 1, the support frame 14 can support the intermittent drive component, and the support frame 14 and the mounting frame 1 are fixed together by reinforcing ribs.

[0029] For further solutions to this utility model, please refer to [link / reference]. Figure 5 and Figure 6 The intermittent drive component includes a grooved roller 8 rotatably mounted on the support frame 14. The grooved roller 8 is driven to rotate by a reduction motor 10 mounted on the support frame 14. A first sleeve 15 is slidably disposed along the axial direction of the grooved roller 8. A first ball bearing 1501 is movably disposed on the first sleeve 15. The first ball bearing 1501 can slide and adapt to the groove 801 formed by the grooved roller 8. The first sleeve 15 is connected to a reciprocating deflector disposed on the support frame 14 through a connecting clamp 11.

[0030] The reciprocating deflection component includes a drive shaft 9 rotatably mounted on the support frame 14, and a second sleeve 16 is slidably sleeved along the axial direction of the drive shaft 9. The second sleeve 16 is fixed to the connecting clamp 11. It also includes a drive shaft 12 rotatably mounted on the support frame 14, the two ends of which are connected to the drive shaft 9 and one of the rotating shafts 602 respectively via a bevel gear set 13.

[0031] Preferably, a limiting groove 901 is formed on the drive shaft 9, and a second ball bearing 1601 that is movably disposed on the inner wall of the second sleeve 16 and is slidably adapted to the limiting groove 901.

[0032] It should be noted that the limiting groove 901 is divided into a first straight groove, a threaded groove and a second straight groove.

[0033] Specifically, when the geared motor 10 is started, the output shaft of the geared motor 10 is fixed to the grooved roller 8, so that when the output shaft rotates, it drives the grooved roller 8 to rotate synchronously. When the grooved roller 8 rotates, the sliding groove 801 on it generates an inclined force on the first ball 1501. Under the restriction of the connecting clamp 11, the first sleeve 15 moves linearly along the axial direction of the grooved roller 8. At the same time, under the push of the connecting clamp 11, the second sleeve 16 moves with the movement of the first sleeve 15. The second sleeve 16 also moves linearly along the axial direction of the drive shaft 9, so as to realize the requirement that the second sleeve 16 can reciprocate relative to the drive shaft 9.

[0034] In the initial state, the second ball 1601 is located in the first or second straight groove, and the drive shaft 9 does not rotate. When the second ball 1601 moves into the threaded groove, the second ball 1601 exerts an inclined force on the threaded groove, causing the drive shaft 9 to rotate. Under the transmission action, the two rotating shafts 602 rotate synchronously. The ball valve 6 changes the flow direction of the cold water in the three-way valve 5, so that the cold water can intermittently enter from the first cooling pipe 3 or the second cooling pipe 4 at both ends of the fin 201, ensuring that the temperature distribution on the fin 201 is more uniform, avoiding local overheating on the fin 201, and accelerating the heat dissipation effect of the radiator.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
