Description

Technical Field

[0001] This utility model relates to the field of aluminum heat dissipation technology, and in particular to a multi-groove surface-supported aluminum heat sink. Background Technology

[0002] The production and widespread use of aluminum radiators have brought convenience to people's production and daily life. Aluminum radiators solve the heat dissipation problem of products by utilizing the thermal conductivity of aluminum, which can quickly conduct heat. The grooves on the surface of aluminum help increase the surface area for air circulation, enhancing the transfer and dissipation of heat, thus achieving a highly efficient heat dissipation effect.

[0003] However, most existing aluminum heat sinks rely on manual wiping of the grooves to clean dust. However, manual wiping can easily scratch the grooves, leaving marks that affect heat conduction and dissipation. Therefore, those skilled in the art have proposed multi-groove surface-supported aluminum heat sinks to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-groove surface-supported aluminum heat sink, which aims to improve the problem that most existing aluminum heat sinks rely on users to manually wipe the grooves to clean dust, which makes the groove surface easily scratched and reduces the heat dissipation efficiency of the heat sink.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a multi-groove surface-supported aluminum heat sink, comprising a heat sink body, a motor fixedly connected to the outside of the heat sink body, two mounting cylinders fixedly connected to the outside of the heat sink body, a connecting rod slidably connected to the outside of the mounting cylinders, a spring sleeved on the outside of the connecting rod, a pressure plate fixedly connected to one end of the connecting rod, a piston fixedly connected to the other end of the connecting rod, a one-way valve fixedly connected to the outside of the piston, a limit block fixedly connected to the inner wall of the mounting cylinder, a one-way valve fixedly connected to the outside of the limit block, and a disassembly assembly installed inside the heat sink body for disassembling the heat sink body.

[0006] As a further description of the above technical solution:

[0007] The disassembly assembly includes two pull rods, which are slidably connected to the outside of the heat sink body. One end of each pull rod is fixedly connected to a baffle, and the other side of the baffle is fixedly connected to a push rod. A second spring is sleeved on the outside of the push rod. A support groove is formed inside the heat sink body, and a connecting groove is formed on the inner wall of the support groove. A first spring is fixedly connected to the inner wall of the connecting groove, and a locking block is fixedly connected to the other end of the first spring. A triangular block is fixedly connected to the outside of the locking block. A fixing block is slidably connected to the bottom of the heat sink body, and two locking slots are formed on the outside of the fixing block.

[0008] As a further description of the above technical solution:

[0009] The output end of the motor is fixedly connected to a transmission rod, and the other end of the transmission rod is fixedly connected to an eccentric wheel.

[0010] As a further description of the above technical solution:

[0011] One end of the spring three is fixedly connected to the outside of the pressure plate, and the other end of the spring three is fixedly connected to the outside of the mounting cylinder.

[0012] As a further description of the above technical solution:

[0013] The mounting cylinder has two air inlet slots on its outer side and multiple sliding grooves on its outer side.

[0014] As a further description of the above technical solution:

[0015] One end of the second spring is fixedly connected to the outer side of the baffle, and the other end of the second spring is fixedly connected to the inner wall of the support groove.

[0016] As a further description of the above technical solution:

[0017] The longitudinal section of the card block is square, and the card block and the card slot are interlocked.

[0018] As a further description of the above technical solution:

[0019] Both of the aforementioned pull rods have anti-slip textures on their exterior.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the eccentric wheel contacts the surface of the pressure plate. When the concave part of the eccentric wheel contacts the pressure plate, the connecting rod drives the piston to slide. At this time, the second check valve opens and the first check valve closes. Air enters the interior of the mounting cylinder through the second check valve. When the protruding part of the eccentric wheel contacts the pressure plate, the piston slides. At this time, the second check valve closes and the first check valve opens. Air is blown onto the surface of the aluminum groove through the slide groove to remove dust from the groove surface. Dust removal can reduce the working temperature of the radiator.

[0022] 2. In this utility model, by pressing the pull rod, the baffle drives the push rod to squeeze the triangular block, and then the triangular block drives the locking block to move, so that the locking block separates from the locking slot. At this time, the heat dissipation body is separated from the fixing block, thus completing the disassembly of the heat dissipation body. When it is necessary to install the heat dissipation body, press the pull rod to fully complete the above steps, so that the heat dissipation body and the fixing block are in contact. Release the pull rod so that the locking block is locked into the locking slot, thus completing the installation of the heat dissipation body. By disassembling the heat dissipation body, its volume and weight can be reduced, making it easier to transport and store. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a multi-groove surface-supported aluminum heat sink, including a heat sink body 1. A motor 25 is fixedly connected to the outside of the heat sink body 1. Two mounting cylinders 2 are fixedly connected to the outside of the heat sink body 1. A connecting rod 21 is slidably connected to the outside of the mounting cylinders 2. A spring 3 20 is sleeved on the outside of the connecting rod 21. A pressure plate 22 is fixedly connected to one end of the connecting rod 21. A piston 16 is fixedly connected to the other end of the connecting rod 21. A one-way valve 2 18 is fixedly connected to the outside of the piston 16. A limit block 15 is fixedly connected to the inner wall of the mounting cylinder 2. A one-way valve 17 is fixedly connected to the outside of the limit block 15. A disassembly assembly is installed inside the heat sink body 1 for disassembling the heat sink body 1.

[0031] Furthermore, firstly, the bottom of the fixing block 4 is brought into contact with the heat source, and then the motor 25 is started. The motor 25 drives the transmission rod 24 to rotate. At the same time, the transmission rod 24 drives the eccentric wheel 23 to rotate, so that the eccentric wheel 23 contacts the surface of the pressure plate 22. When the concave part of the eccentric wheel 23 contacts the surface of the pressure plate 22, the spring 20 causes the pressure plate 22 to drive the connecting rod 21 to slide. Then, under the traction of the connecting rod 21, the piston 16 slides along the inner wall of the mounting cylinder 2. At this time, When check valve 18 is open and check valve 17 is closed, air enters the interior of mounting cylinder 2 through check valve 18. When the protrusion of eccentric wheel 23 contacts pressure plate 22, connecting rod 21 drives piston 16 to slide along the inner wall of mounting cylinder 2. At this time, check valve 17 is open and check valve 18 is closed. Piston 16 pushes air through slide groove 5 to blow towards the aluminum plate groove, cleaning the dust on the surface of the aluminum plate groove. Dust removal can keep the surface of the heat sink clean and protect electronic components from overheating.

[0032] Reference Figure 1 and Figure 2 The disassembly assembly includes two pull rods 3. The pull rods 3 are slidably connected to the outside of the heat sink body 1. One end of the pull rod 3 is fixedly connected to a baffle 11. The other side of the baffle 11 is fixedly connected to a push rod 8. A second spring 10 is sleeved on the outside of the push rod 8. A support groove 9 is opened inside the heat sink body 1. A connecting groove 6 is opened on the inner side wall of the support groove 9. A first spring 7 is fixedly connected to the inner wall of the connecting groove 6. A locking block 13 is fixedly connected to the other end of the first spring 7. A triangular block 14 is fixedly connected to the outside of the locking block 13. A fixing block 4 is slidably connected to the bottom of the heat sink body 1. Two locking slots 12 are opened on the outside of the fixing block 4.

[0033] Furthermore, when it is necessary to disassemble the heat sink body 1, press the two inner pull rods 3 simultaneously. The pull rods 3, along with the baffle 11, slide along the inner wall of the support groove 9. At this time, the baffle 11 drives the push rod 8 to press the triangular block 14 on one side, causing the triangular block 14 to move the locking block 13 until the locking block 13 is completely retracted into the interior of the connecting groove 6, thereby separating the heat sink body 1 from the fixing block 4, thus completing the disassembly of the heat sink body 1. When it is necessary to install the heat sink body 1, press the pull rod 3 and repeat the above steps. At this time, the second spring 10 is in a compressed state, which brings the inner wall of the heat sink body 1 into contact with the outer side of the fixing block 4. Then, release the pull rod 3. Under the elastic force of the second spring 10, the inner wall of the outer slot 12 of the locking block 13 fits into contact, thus completing the installation of the heat sink body 1. By disassembling the heat sink body 1, its position can be easily rearranged or its layout adjusted to meet specific design requirements or optimize performance.

[0034] Reference Figure 1 , Figure 3 and Figure 4The output end of the motor 25 is fixedly connected to the transmission rod 24, and the other end of the transmission rod 24 is fixedly connected to the eccentric wheel 23; one end of the spring 20 is fixedly connected to the outside of the pressure plate 22, and the other end of the spring 20 is fixedly connected to the outside of the mounting cylinder 2.

[0035] Furthermore, the output end of the motor 25 drives the transmission rod 24 to rotate, which in turn drives the eccentric wheel 23 to rotate synchronously, ensuring the high efficiency of cleaning the groove dust; the spring 3 20 is connected to the pressure plate 22 and the mounting cylinder 2, making the spring 3 20 more stable and extending its service life. At the same time, the spring 3 20 reacts to the pressure plate 22, allowing the pressure plate 22 to quickly reset.

[0036] Reference Figure 1 , Figure 3 and Figure 4 Two air inlet slots 19 are provided on the outer side of the mounting cylinder 2, and multiple sliding grooves 5 are provided on the outer side of the mounting cylinder 2.

[0037] Furthermore, the air intake groove 19 allows air to circulate inside the mounting cylinder 2, while ensuring that the air pressure inside the mounting cylinder 2 is consistent with the external air pressure. The air inside the mounting cylinder 2 is blown into the aluminum groove through the slide groove 5 to clean the dust on the surface of the groove.

[0038] Reference Figure 1 and Figure 2 One end of the second spring 10 is fixedly connected to the outer side of the baffle 11, and the other end of the second spring 10 is fixedly connected to the inner wall of the support groove 9; the longitudinal section of the locking block 13 is square, and the locking block 13 and the locking groove 12 are plugged into each other; the two pull rods 3 are both provided with anti-slip texture on the outside.

[0039] Furthermore, the baffle 11 is limited by the spring 2 10 to prevent the baffle 11 from sliding freely along the inner wall of the support groove 9 and affecting the stability of the locking block 13; the locking block 13 is locked into the inner wall of the slot 12 to fix the heat dissipation body 1, ensuring the stability and reliability of the heat dissipation body 1; the anti-slip texture increases the friction of the pull rod 3, making it easier for the operator to operate the pull rod 3.

[0040] Working principle: First, the bottom of the fixing block 4 is brought into contact with the heat source, and then the motor 25 is started. The motor 25 drives the transmission rod 24 to rotate, which in turn drives the eccentric wheel 23 to rotate simultaneously, so that the eccentric wheel 23 contacts the surface of the pressure plate 22. When the concave part of the eccentric wheel 23 contacts the surface of the pressure plate 22, under the elastic force of the spring 3 20, the pressure plate 22 drives the piston 16 to slide through the connecting rod 21. At this time, the one-way valve 2 18 opens and the one-way valve 1 17 closes. Air enters the interior of the mounting cylinder 2 through the one-way valve 2 18. When the protrusion of the eccentric wheel 23 contacts the pressure plate 22, the connecting rod 21 drives the piston 16 to slide along the inner wall of the mounting cylinder 2. At this time, the one-way valve 1 17 opens and the one-way valve 2 18 closes. Under the push of the piston 16, the air is blown through the slide groove 5 to the groove of the aluminum plate, cleaning the dust in the groove of the aluminum plate, allowing the air to flow more freely, and the heat to be dissipated more effectively, thus improving the heat dissipation efficiency of the radiator.

[0041] Additionally, when it is necessary to disassemble the heat sink body 1, press both pull rods 3 simultaneously, causing the baffle 11 to slide. At this time, the baffle 11 presses the triangular block 14 through the push rod 8, causing the triangular block 14 to move the locking block 13 to one side until the locking block 13 disengages from the slot 12, thereby separating the heat sink body 1 from the fixing block 4, thus completing the disassembly of the heat sink body 1. When it is necessary to install the heat sink body 1, press the pull rod 3 and repeat the above steps. At this time, the second spring 10 is in a compressed state, bringing the heat sink body 1 into contact with the outside of the fixing block 4. Then release the pull rod 3, and under the elastic force of the second spring 10, the locking block 13 is inserted into the slot 12, thus completing the installation of the heat sink body 1. By disassembling the heat sink body 1, it is convenient to check whether the heat sink is damaged or malfunctioning, so as to ensure the normal operation of the equipment.

[0042] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
