Description

Technical Field

[0001] The utility model relates to the technical field of heat sinks, in particular to a high-efficiency heat sink. Background Art

[0002] A heat sink is a device that dissipates heat from heat-prone electronic components in electrical appliances. It is typically made of aluminum alloy, brass, or bronze in the form of plates, sheets, or multiple sheets. For example, the CPU in a computer requires a fairly large heat sink, as do the power tubes, line tubes, and amplifier tubes in a television. Generally, a heat sink is coated with a layer of thermally conductive silicone grease on the contact surface between the electronic component and the heat sink. This allows the heat generated by the component to be more efficiently transferred to the heat sink and then dissipated into the surrounding air. A search revealed a Chinese patent application with authorization publication number CN219843898U that discloses a high-efficiency graphene heat sink, comprising a heat dissipation module and a protective module. The heat dissipation module includes a graphene plate, multiple heat sinks connected to the top of the plate, and an adhesive layer applied to the bottom of the plate. In the utility model, the graphene plate is attached to the position where heat dissipation is required through the adhesive layer, and then the heat is transferred to multiple heat sinks. During this period, two micro motors rotate the gears connected to the two, and the two gears turn in opposite directions. Then, the shell moves toward the outside of the graphene plate under the influence of the gear plate, and then the touch switch is touched, and multiple cooling fans work and blow away the heat in multiple air outlet channels, effectively taking away the temperature of multiple heat sinks. It can not only protect the heat sink when the device is idle, but also improve the heat dissipation efficiency of the heat sink when the heat sink is working. It is multifunctional and comfortable to use.

[0003] However, in actual use, due to the lack of linkage facilities, the two shells located on both sides of the heat sink need to be driven by two sets of micro motors to rotate gears respectively, so that the two gear plates can drive the shells to move respectively. Such a structure not only increases the structural cost of the heat sink, but also is not conducive to subsequent maintenance. Utility Model Content

[0004] In order to solve the problem of high cost of existing heat sink structures, the present invention provides a high-efficiency heat sink. In view of the above problems, the technical solution proposed by the present invention is:

[0008] Furthermore, the top surface of the fan is flush with the inner bottom surface of the housing.

[0009] The beneficial effect of adopting the above further solution is that, through the positional relationship between the fan and the housing, it is easy to ensure that the housing slides smoothly on both sides of the heat sink body.

[0010] Furthermore, the top surface of the shell is provided with a plurality of circular holes, and a breathable flap is provided inside the plurality of circular holes. The breathable flap includes a circular cover, and the outer walls of the circular cover are respectively connected to a rotating shaft on both sides, and the inner walls of the circular hole are respectively provided with holes rotatably connected to the rotating shaft.

[0011] The beneficial effect of adopting the above further solution is that the circular cover can be turned over inside the circular hole by rotating the rotating shaft inside the hole.

[0012] Furthermore, first magnetic sheets are embedded and installed on both sides of the outer wall of the circular cover, and second magnetic sheets are embedded and installed on both sides of the inner wall of the circular hole, and the second magnetic sheets are in the same horizontal plane as the first magnetic sheets.

[0013] The beneficial effect of adopting the above further solution is that the round cover can be placed horizontally inside the round hole due to the mutual adsorption of the second magnetic sheet and the first magnetic sheet.

[0014] Furthermore, the heat sink body includes a sheet body, and air holes are formed on the bottom surface of the sheet body.

[0015] The beneficial effect of adopting the above further solution is that, through the provision of the air holes, the air flow in the cylinder can enter the interior of the sheet, thereby accelerating the release of heat.

[0016] Furthermore, the bottoms of the two shells are provided with recesses that match the fixing plates.

[0017] The beneficial effect of adopting the above further solution is that, by providing the recess, the two shells can avoid being obstructed by the fixing plate when contacting each other.

[0018] Furthermore, one end of the worm passes through one side of one of the fixing plates and is connected to a crank.

[0019] The beneficial effect of adopting the above further solution is that the rotation of the worm is made more convenient through the connection and use of the crank.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The high-efficiency heat sink has a linkage structure through the mutual cooperation of the shell, the lead screw and the adjustment component, which makes the two shells more convenient to adjust, effectively reduces the structural cost, and is beneficial to subsequent maintenance. Among them, by prompting the worm wheel to rotate forward and reverse, and coordinating the meshing relationship between the worm wheel and the worm, the worm can drive the worm wheel to rotate forward and reverse synchronously, and then cooperate with the set connection between the worm wheel and the lead screw to make the lead screw rotate forward and reverse, and by arranging threads with opposite rotation directions on both sides of the lead screw, the lead screw can rotate and prompt the two shells to slide away or close to each other, thereby realizing the function of linkage adjustment.
