Description

Technical Field

[0001] This utility model relates to a computer-aided heat sink, belonging to the technical field of heat sinks. Background Technology

[0002] Computers, as electronic products, often generate high temperatures during use, which can damage the computer and cause property loss in severe cases. Therefore, they are often equipped with cooling pads to dissipate heat and prevent accidents.

[0003] For example, utility model patent CN212900732U discloses a foldable and retractable computer-aided cooling rack, relating to the field of computer-aided tools. Addressing the problems of traditional cooling racks being inconvenient to fold and store, and difficult to adjust the computer's angle after use, this utility model proposes the following solution: It includes a first support plate and a second support plate. A first front baffle is fixedly installed at the middle of the side wall surface of the first support plate, and a rotating shaft is movably installed on the side wall of the first support plate. A second support plate is fixedly installed on the side wall away from the first support plate, and the first and second support plates form the cooling rack. A placement groove is provided on the upper surface of the cooling rack. This utility model has a novel structure and solves the problems of traditional cooling racks being inconvenient to fold and store, and difficult to adjust the computer's angle after use.

[0004] However, the above solution has the following shortcomings in practical use:

[0005] The patent mentions that the first and second fans are driven by the first and second motors, respectively. However, the installation positions of the first and second fans are fixed and cannot be adjusted. In addition, the opening positions of the heat dissipation holes of different brands of computers are not consistent. If the fan position is misaligned with the computer's heat dissipation holes or the airflow is insufficient, the heat dissipation effect may be greatly reduced.

[0006] 2. In the above-mentioned device, the first front baffle and the first rear baffle are respectively fixedly installed on the front and rear sides of the first support plate, and the second front baffle and the second rear baffle are respectively fixedly installed on the front and rear sides of the second support plate. Since the installation method is a fixed connection, it is not convenient to disassemble. However, after long-term use, a lot of dust will adhere to the first front baffle, the first rear baffle, the second front baffle, and the second rear baffle. The accumulation of dust will affect the normal air circulation, affect the normal operation of the fan, increase energy consumption, and reduce the service life of the fan. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a computer auxiliary heat dissipation bracket, which realizes the adjustment of the fan position to meet the heat dissipation needs of computers of different sizes and models. At the same time, the front and rear baffles can be disassembled, and the dust attached to their surfaces can be cleaned after long-term use.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] A computer-aided heat sink includes at least two symmetrically distributed mounting frames, with a pivot between the two mounting frames. Each mounting frame is rotatably connected to the pivot. Each mounting frame has an internal movable cavity, within which a fan mounting base is movably mounted, and a fan assembly is rotatably connected. Each of the opposite outer walls of the mounting frames has an exhaust duct communicating with the movable cavity. A ventilation plate is detachably fixed within the exhaust duct. An adjustment mechanism is also provided on one side wall of each mounting frame. The adjustment mechanism includes a displacement component connected to the fan mounting base, which controls the horizontal movement of the fan mounting base within the movable cavity. A locking component is also provided on one side of the displacement component to restrict the rotational freedom of the displacement component.

[0010] In this design, exhaust ducts are provided on the front and rear end faces of the mounting frame, respectively, which are connected to the inner cavity of the mounting frame. A plate is fixedly connected to the exhaust duct by locking screws. The plate has ventilation slots. When the fan assembly is working, it will draw in outside air from one exhaust duct (the back of the mounting frame) and then exhaust the air to the computer through the other exhaust duct (the front of the mounting frame). The air enters the reserved heat dissipation holes in the computer to dissipate heat from the internal components of the computer.

[0011] It should be explained that the plate and the exhaust duct are fixed together by locking screws. After the device has been used for a long time, a lot of dust will be attached to the ventilation duct and filter screen on the surface of the plate. The dust will affect the air circulation. By removing the plate, the dust in the filter screen and ventilation duct can be cleaned to avoid dust accumulation.

[0012] In addition, the fan mounting base can be moved horizontally within the mounting frame by a displacement component, thereby adjusting the airflow direction and position of the fan assembly. This allows the device to meet the needs of different products and models of computers, thus expanding its applicability.

[0013] Preferably, the ventilation plate has: a plate body disposed in the exhaust trough, the plate body having a plurality of ventilation troughs, and a filter screen being fitted into each ventilation trough.

[0014] In this design, the panel is detachably and fixedly installed inside the exhaust duct, and several ventilation slots are opened on the surface of the panel. The ventilation slots are connected to the inner cavity of the mounting frame. When the fan assembly is working, the air blown out can be smoothly discharged through the ventilation slots. At the same time, a filter screen is installed in each ventilation slot to filter dust and impurities in the outside air, preventing dust and impurities from entering the mounting frame and causing damage to the fan assembly.

[0015] Preferably, each of the exhaust ducts is also fixedly installed with a connecting plate, which is arranged around the exhaust duct and has a plurality of threaded holes. One side wall of the plate rests on the connecting plate, and the plate has through holes corresponding to the plurality of threaded holes. Each through hole is provided with a locking screw, and the threaded end of the locking screw is threaded into the threaded hole.

[0016] In this design, through holes are provided at the four edges of the plate, and locking screws are placed in the through holes (the threaded end of the locking screw is located in the through hole). A connecting plate is fixedly installed around the inner wall of the exhaust duct. The connecting plate has threaded holes corresponding to the through holes, and the threaded holes and the threaded end of the locking screw are threadedly engaged.

[0017] During actual assembly, the plate is placed in the exhaust duct and rests on one side of the connecting plate. The plate is located on the side of the connecting plate away from the inner cavity of the mounting frame. After the threaded hole and through hole are aligned, the threaded end of the locking screw is passed through the through hole and then threaded into the threaded hole to achieve assembly and fixation of the plate.

[0018] Preferably, the displacement component includes: an adjustment seat fixedly installed on one side wall of the mounting frame, an adjustment screw rotatably connected inside the adjustment seat, and a sliding groove communicating with the inner cavity of the adjustment seat is provided on the inner side wall of the mounting frame. An adjustment block is slidably connected in the sliding groove. One end of the adjustment block is fixedly connected to the fan mounting base, and the other end is threadedly connected to the adjustment screw. One end of the adjustment screw extends to the outside of the adjustment seat and is fixedly installed with a knob. A guide groove is provided on the other side inner wall of the mounting frame opposite to the sliding groove. A guide block is fixedly connected to the side wall of the fan mounting base and slidably connected in the guide groove.

[0019] In this design, the adjustment screw can be rotated manually by gripping the knob. The adjustment screw drives the adjustment block, which is threadedly connected to it, to slide horizontally in the sliding groove. The adjustment block is fixedly installed on the side wall of the fan mounting base. Therefore, when the adjustment block moves, it will drive the fan mounting base to move, thereby adjusting the horizontal position of the fan mounting base and thus adjusting the position of the air blown out by the fan assembly.

[0020] It should be noted that a guide block is also installed on the other side wall of the fan mounting base. At the same time, a guide groove is opened on the inner side wall of the mounting frame, which is aligned with and parallel to the sliding groove. The guide block is slidably connected in the guide groove. The cooperation between the guide block and the guide groove can ensure the stability of the horizontal movement of the fan mounting base. At the same time, the guide block and the guide groove can support the fan mounting base.

[0021] Preferably, the locking assembly includes: one end of the adjusting screw away from the knob extends to the outside of the adjusting seat and is fixedly connected to a turntable; a limiting groove is formed on the outer peripheral wall of the turntable; a moving groove is formed on the side wall of the adjusting seat; a guide rod is fixedly connected in the moving groove; a limiting rod is slidably connected to the guide rod; one end of the limiting rod is inserted into the limiting groove; and a return spring is sleeved on the outside of the guide rod on the side of the limiting rod away from the adjusting screw.

[0022] In this scheme, when it is necessary to control the rotation of the adjusting screw, the operator manually pulls the limit rod along the moving groove (in the direction away from the adjusting screw). When the limit rod moves, it will compress the return spring, and at the same time, the limit rod will disengage from the limit groove. At this time, the operator can control the rotation of the adjusting screw by gripping the knob. When the adjusting screw rotates to the specified angle, the limit groove and the limit rod are aligned. Then, the operator releases the limit rod. Under the rebound kinetic energy of the return spring, the limit rod moves closer to the adjusting screw along the moving groove. At the same time, the limit rod inserts into the limit groove to lock the turntable. The turntable is fixedly installed at the end of the adjusting screw, and the turntable thus restricts the rotation of the adjusting screw, thereby limiting the position of the fan mounting base.

[0023] Preferably, multiple limiting grooves are provided and are distributed at equal angles on the outer peripheral wall of the turntable.

[0024] In this design, multiple limiting slots can be set to increase the movement position of the fan mounting bracket, while also allowing the device to provide cooling assistance for different computer models.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. The plate and the exhaust duct are fixed together by locking screws. After the device has been used for a long time, a lot of dust will be attached to the ventilation duct and filter screen on the surface of the plate. The dust will affect the air circulation. By removing the plate, the dust in the filter screen and ventilation duct can be cleaned to avoid dust accumulation.

[0027] 2. The fan mounting base can be moved horizontally within the mounting frame by the displacement component in this device, thereby adjusting the airflow direction and position of the fan assembly. This allows the device to meet the needs of different products and models of computers, thus enriching its applicability. Attached Figure Description

[0039] 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.

[0040] Please see Figure 1-5 This utility model provides a technical solution:

[0041] A computer-aided heat sink includes at least two symmetrically distributed mounting frames 1, with a pivot 11 between the two mounting frames 1. Each mounting frame 1 is rotatably connected to the pivot 11. Each mounting frame 1 has a movable cavity 12 inside, in which a fan mounting base 2 is movably mounted, and a fan assembly 21 is rotatably connected. Exhaust troughs 13 communicating with the movable cavity 12 are provided on the opposite outer walls of the mounting frames 1. A ventilation plate 3 is detachably fixedly mounted in the exhaust troughs 13. An adjustment mechanism 4 is also provided on one side wall of the mounting frame 1. The adjustment mechanism 4 has a displacement component 41 connected to the fan mounting base 2, which controls the horizontal movement of the fan mounting base 2 within the movable cavity 12.

A guide block 417 is fixedly connected to the side wall of the fan mounting base 2 and is slidably connected inside the guide groove 416.

[0052] In this solution, the knob 415 can be replaced with a miniature servo motor to reduce the amount of manual turning. At the same time, a PLC controller and a memory module are added. The PLC controller can control the miniature servo motor to work, and the memory module records the data of the fan mounting base 2 moving to various positions, so that it can be easily adjusted by one button when used manually.

[0053] Furthermore, the locking assembly 42 includes: an adjusting screw 412 extending away from the knob 415 to the outside of the adjusting seat 411 and fixedly connected to a turntable 421; a limiting groove 422 is formed on the outer peripheral wall of the turntable 421; a moving groove 423 is formed on the side wall of the adjusting seat 411; a guide rod 424 is fixedly connected in the moving groove 423; a limiting rod 425 is slidably connected to the guide rod 424; one end of the limiting rod 425 is inserted into the limiting groove 422; and a return spring 426 is sleeved on the outside of the guide rod 424 on the side of the limiting rod 425 away from the adjusting screw 412.

[0054] Furthermore, multiple limiting grooves 422 are provided and are distributed at equal angles on the outer peripheral wall of the turntable 421.

[0055] Specifically, the limiting grooves 422 are opened at equal angles on the surface of the turntable 421.
