The cover plate 200 is embedded in the bottom opening of the housing 100 and closes the opening. The housing 100 and the cover plate 200 together form a housing for accommodating the motherboard 300, the hard disk 400, and the C The chassis comprises a CPU 500 and a heat dissipation assembly 600; the heat dissipation assembly 600, the mainboard 300 and the hard disk 400 are stacked in parallel in the chassis, and the mainboard 300 is fixed to the cover plate 200 by bolts, the hard disk 400 is fixed to the mainboard 300 by bolts, the hard disk 400 is connected to the mainboard 300 for communication, and the CPU 500 is arranged on the side of the mainboard 300 facing away from the hard disk 400 and is connected to the mainboard 300 for communication; the heat dissipation assembly 600 is arranged above the CPU 500 and exhausts the hot air around the CPU 500 through the second vent 1002 to the outside of the housing 100 by rotating the exhaust fan;

[0036] It also includes dual microphones (not shown in the figure) and primary and secondary antennas (not shown in the figure). The dual microphones work independently without affecting each other, can receive sounds from different directions, and have a high signal-to-noise ratio, especially in a noisy environment.

The rotation of the blades of the exhaust fan 1 draws air, and the hot air in the chassis is discharged to the rear side of the chassis through the radiator 2 and the second vent 1002, so that the cold air on the left and right sides of the chassis enters the chassis through the first vent 1001, realizing the flow of air inside and outside the chassis; it should be noted that the radiator 2 is a fin-type aluminum alloy radiator in the prior art.

[0038] The temperature-sensing trigger structure 3 is arranged between the air inlet of the exhaust fan 1 and the CPU 500 and is attached to the CPU 500 through a thermally conductive adhesive. The temperature-sensing trigger structure 3 receives the heat generated by the CPU 500 when it is working and dissipates the heat to the surrounding environment, heating the air in the environment. The temperature-sensing trigger structure 3 is a multi-surface structure to increase the heat dissipation surface area so that the heat generated by the CPU 500 when it is working can be quickly dissipated; the inner side of the temperature-sensing trigger structure 3 is connected to an adjustment ring 4, and the temperature-sensing trigger structure 3 has a temperature threshold. When the temperature of the temperature-sensing trigger structure 3 exceeds its own temperature threshold, the temperature-sensing trigger structure 3 is turned off. When the value is reached, the structure connected to the adjustment ring 4 on the temperature-sensing trigger structure 3 moves toward the exhaust fan 1, pushing the adjustment ring 4 to move toward the exhaust fan 1; multiple enhanced ventilation structures 5 are distributed on the inner side of the adjustment ring 4 in a circular array with the central axis of the adjustment ring 4 as the center, each enhanced ventilation structure 5 extends into the adjustment ring 4 and rotates along the adjustment ring 4, and each enhanced ventilation structure 5 is rotationally connected to the blades of the exhaust fan 1 through an axis; multiple enhanced ventilation structures 5 are tiltedly arranged between the air inlet of the exhaust fan 1 and the temperature-sensing trigger structure 3, and the tilt direction of the enhanced ventilation structure 5 is consistent with the direction of the exhaust fan 1. The rotation directions are opposite, so that the windward surface of the enhanced air extraction structure 5 and the windward surface of the exhaust fan 1 face the same direction, and the windward surface of the enhanced air extraction structure 5 and the windward surface of the exhaust fan 1 blades form a two-level air extraction structure to achieve high-speed air extraction; the enhanced air extraction structure 5 rotates along the adjustment ring 4 as the blades rotate, and swings around the axis connecting the blades and the enhanced air extraction structure 5 as the adjustment ring 4 moves toward the exhaust fan 1, increasing the inclination angle, so that the side of the windward surface of the enhanced air extraction structure 5 close to the CPU 500 is closer to the CPU 500, and the side away from the CPU 500 is farther away from the CPU 500, so that C The heat just emitted by PU500 can be lifted up away from CPU500 by the rotating windward surface, achieving the effect of quickly extracting heat, and the cross-sectional height of the ventilation duct formed between the windward surface of the enhanced exhaust structure 5 and the leeward surface of the exhaust fan 1 blade is gradually reduced against the rotation direction of the enhanced exhaust structure 5, so that the hot air picked up by the windward surface continuously moves upward away from CPU500 and continuously accelerates during the flow in the ventilation duct, so that the hot air can enter the working area of ​​the exhaust fan 1 blade at a faster speed after leaving the ventilation duct, further achieving the effect of quickly extracting heat.

[0039] A plurality of resistance structures 6 and a plurality of enhanced ventilation structures 5 are connected together by rotating axes one by one. When the inclination angle of the enhanced ventilation structure 5 increases, the axis connecting the resistance structure 6 and the enhanced ventilation structure 5 moves upward synchronously. Each resistance structure 6 is installed on the blade of the exhaust fan 1 and rotates with the rotation of the blade. The resistance structure 6, the blade of the exhaust fan 1 and the enhanced ventilation structure 5 have the same rotation speed and direction. The resistance structure 6 generates centrifugal force during the rotation of the blade of the exhaust fan 1. This centrifugal force acts on the enhanced ventilation structure 5 when the inclination angle of the enhanced ventilation structure 5 increases, thereby eliminating the increased wind resistance when the inclination angle of the enhanced ventilation structure 5 increases, so as to ensure that the inclination angle of the enhanced ventilation structure 5 can be effectively increased, thereby effectively improving the heat extraction efficiency.

When the temperature of the temperature sensing trigger structure 3 exceeds its own temperature threshold, that is, when the temperature of the memory alloy spring 35 exceeds the minimum temperature value for its stretching, the memory alloy spring 35 stretches to push the slide 34 to move up in the heat conducting tube 32, and push the adjustment ring 4 to move up.

[0041] The adjusting ring 4 includes a mounting ring 41, which is an annular structure with an L-shaped cross-section. A retaining ring 42 is embedded on the inner wall of the mounting ring 41. An annular adjusting groove 43 is formed between the retaining ring 42 and the mounting ring 41. The outer wall of the mounting ring 41 is fixed to the slide 34. The memory alloy spring 35 is heated and extended to push the slide 34 and the adjusting groove 43 upward. The memory alloy spring 35 is cooled and contracted to reset, driving the slide 34 and the adjusting groove 43 downward, thereby realizing the change in the setting height of the adjusting groove 43 controlled by temperature changes.

The windward surface of the main air intake plate 51 is in the same direction as the windward surface of the exhaust fan 1 blade. The main air intake plate 51 is arranged on the inner side of the adjustment ring 4. An adjustment shaft 53 is fixed to one end of the main air intake plate 51. The adjustment shaft 53 is embedded in the adjustment groove 43. The adjustment shaft 53 slides in the adjustment groove 43 and can move up and down with the up and down movement of the adjustment groove 43. The other end of the main air intake plate 51 is fixed to a secondary air intake plate 52 and a support shaft 54. A first suspension rod 7 is rotatably sleeved on the support shaft 54. The first suspension rod 7 is fixed to the exhaust fan 1. The lower surface of the blade; the blades of the exhaust fan 1 rotate, and the main air intake plate 52 is driven to rotate through the first suspension rod 7 and the support shaft 54, driving the support groove 53 to slide in the adjustment groove 43; when the adjustment groove 43 moves upward, the main air intake plate 51 is pushed to swing around the support shaft 54 ​​through the adjustment shaft 53, so that the inclination angle of the main air intake plate 51 increases, and the auxiliary air intake plate 52 is lifted, so that the side of the main air intake plate 51 on the windward surface close to the CPU500 is closer to the CPU500, and the side away from the CPU500 is farther away from the CPU500; a connecting shaft 55 is fixed to the end of the auxiliary air intake plate 52 away from the main air intake plate 51, and the connecting shaft 55 is rotatably connected to the resistance structure 6.

[0043] The resistance structure 6 includes a slot frame 61, a connecting rod 62 and a push plate 621, wherein a centrifugal slot 63 and a guide slot 64 are arranged in the slot frame 61, both of which are arc-shaped slots, the central axis of the guide slot 64 is in the same straight line as the central axis of the blade of the exhaust fan 1, the radius of the centrifugal slot 63 is smaller than the radius of the guide slot 64, the centrifugal slot 63 is tangentially connected to one side of the guide slot 64, and the guide slot 64 runs through the upper and lower surfaces of the slot frame 61; a second suspension rod 8 is fixed to the side of the upper surface of the slot frame 61 away from the guide slot 64, and the second suspension rod 8 is fixed to the lower surface of the blade of the exhaust fan 1, so that the slot frame 61 rotates with the rotation of the blade;

The push plate 621 swings relative to the push shaft 623 during the movement along the guide groove 64; when the inclination angle of the main air-circulating plate 51 increases to the maximum value, the top end of the supporting plate 622 abuts against the bottom end of the slot frame 61 to avoid limiting the maximum rising height of the main air-circulating plate 51 and the auxiliary air-circulating plate 52, and avoid contact with the blades of the exhaust fan 1.

[0045] A push rod 631 and a sphere 632 are provided in the centrifugal groove 63. The sphere 632 is arranged on one side of the push rod 631 and away from the guide groove 64. The push rod 631 and the push plate 621 abut against each other. As the blades of the exhaust fan 1 rotate, the sphere 632 rotates and moves along the centrifugal groove 63 to the side of the guide groove 64, pushing the push rod 631 to squeeze the push plate 621, driving the push plate 621 to move in the guide groove 64 toward the side of the auxiliary air vent plate 52. During the movement of the push rod 631 in the centrifugal groove 63 and the guide groove 64, the push rod 631 bends and deforms as the centrifugal groove 63 and the guide groove 64 bend, so as to facilitate the push rod 631 to move in the centrifugal groove 6 3 and guide groove 64; the side of the push rod 631 that contacts the push plate 621 is a hemispherical surface, and the side of the push plate 621 that contacts the push rod 631 is inclined toward the side away from the push rod 631, and gradually moves away from the push rod 631 from top to bottom, so that the contact between the push rod 631 and the push plate 621 is point contact, and the push rod 631 can apply an upward force to the push plate 621, which plays a role in supporting the push plate 621 and the connecting rod 62, and supporting the auxiliary air-circulating plate 52 and the main air-circulating plate 51, thereby eliminating the wind resistance increased when the inclination angles of the main air-circulating plate 51 and the auxiliary air-circulating plate 52 increase.

[0046] The upper surface of the main air-shaft plate 51 is flush with the upper surface of the auxiliary air-shaft plate 52. Both the upper surface of the main air-shaft plate 51 and the upper surface of the auxiliary air-shaft plate 52 are windward surfaces and are used to lift hot air during rotation.

[0047] A baffle 541 is fixed to one end of the support shaft 54 ​​away from the main air intake plate 51, and the baffle 541 abuts against one end of the first suspension rod 7 away from the main air intake plate 51.
