Description

Technical Field

[0001] This invention relates to the field of computer host power supply technology, specifically to a multi-channel voltage-balanced ATX modular power supply for computer hosts. Background Technology

[0002] With the rapid development of computer technology, the stability and reliability of the internal components of a computer host, as the core device for information processing, are of paramount importance. Among these, the power supply, as the core of the computer host's energy supply, directly affects the operating efficiency and safety of the entire system. ATX modular power supplies, due to their multi-voltage output characteristics, can provide stable and balanced power support to the various components within the computer host, thereby ensuring stable system operation.

[0003] However, ATX modular power supplies face the dual challenges of heat dissipation and dust accumulation during prolonged use. Power supplies are usually equipped with fans to draw outside air into the power supply, thereby helping to dissipate heat from the power supply components. During the operation of the fan, dust particles in the air are drawn into the power supply and gradually accumulate on the circuit board. Over time, the dust accumulated on the circuit board not only reduces the heat dissipation efficiency of the power supply, but may also cause the components on the circuit board to age, or even cause short circuits and other faults. In severe cases, it can damage the power supply and affect the normal operation of the entire computer system. Summary of the Invention

[0004] This invention provides a multi-channel voltage-balanced ATX modular power supply for computer hosts to solve the problem that existing computer power supply fans are prone to damaging the power supply.

[0005] The present invention provides a multi-channel voltage-balanced ATX modular power supply for computer hosts, which adopts the following technical solution:

[0006] A multi-channel voltage-balanced ATX modular power supply for computer hosts includes a casing, a fan, a regulator, and a control unit.

[0007] The housing has an internal cavity containing a circuit board. The housing has an air inlet and an air outlet connecting the cavity to the external environment. Multiple wiring ports are provided on the housing, each electrically connected to the circuit board. Each wiring port can be connected to a computer motherboard via a wire. An interface is provided on the housing for connecting a power cord, and this interface is electrically connected to the circuit board. The fan includes a rotating disk and multiple fan plates. The rotating disk is rotatably mounted in the cavity, and one end of each fan plate is rotatably connected to the rotating disk. The fan plates rotate around the rotating disk. The rotating disks are evenly distributed around their circumference, and the axial direction of the rotating disks is the same as the length extension direction of the fan plates. The adjusting component includes an adjusting ring and an adjusting rod. The adjusting ring abuts against the rotating disk and rotates synchronously with the rotating disk. Multiple adjusting rods are provided, each of which is fixedly connected to the adjusting ring and rotatably connected to the end of a fan plate. The adjusting ring can slide relative to the rotating disk, making the adjusting ring eccentric to the rotating disk. The control component is used to control the sliding mode of the adjusting ring relative to the rotating disk according to the computer's power-on status.

[0008] Furthermore, the adjusting component also includes an adjusting cylinder, a first connecting ring, and a second connecting ring. The first connecting ring is fixedly connected to the housing and has two mounting grooves. Each mounting groove extends radially along the first connecting ring, and the two mounting grooves extend perpendicularly to each other. The second connecting ring is coaxially rotatably connected to the adjusting ring. Two adjusting cylinders are provided, each of which is fixedly disposed in one of the mounting grooves. The output shafts of the two adjusting cylinders are simultaneously rotatably connected to the second connecting ring. The controlling component can control the length of the two adjusting cylinders.

[0009] Furthermore, the regulating cylinder is an electrically controlled telescopic cylinder, and the control unit can independently control any one of the electrically controlled telescopic cylinders.

[0010] Furthermore, the housing is equipped with a drive motor, which drives the rotating disk to rotate. The drive motor is electrically connected to the circuit board via wires, and the control unit can control the drive motor to rotate at a constant speed.

[0011] Furthermore, the drive motor has a start / stop button, which is the same as the power button on a computer.

[0012] Furthermore, the control component is a control board, which is integrated into a circuit board. The control board contains a control program, which is used to control the length change of the adjusting cylinder according to the computer's power-on status.

[0013] Furthermore, the control procedure includes the following steps:

[0014] When the computer starts up, the control program controls the two regulating cylinders to change length in a first preset manner;

[0015] After the computer runs for a preset period of time, the control program controls the two regulating cylinders to change length in a second preset manner.

[0016] Furthermore, the first preset method is to control the two regulating cylinders to extend simultaneously, and after the two regulating cylinders extend, the deflection angle of the fan plate near the air inlet is greater than the deflection angle of the fan plate away from the air inlet.

[0017] Furthermore, the second preset method is to control the two adjusting cylinders to extend simultaneously, and after the two adjusting cylinders extend, the deflection angle of the fan plate closer to the circuit board is greater than the deflection angle of the fan plate farther away from the circuit board.

[0018] Furthermore, the control program has a timer inside, which is used to start after the computer runs for a preset time period, and the length change mode of the two regulating cylinders is switched from the first preset mode to the second preset mode.

[0019] The beneficial effects of this invention are as follows: This invention provides a multi-channel voltage balancing ATX modular power supply for computer hosts, comprising a casing, a fan, an adjusting component, and a control component. By setting the control component, when the computer is powered on, a rotating disk begins to rotate around its own axis. Multiple fan plates on the rotating disk rotate synchronously around the axis of the rotating disk. At this time, the multiple fan plates can induce gas flow within the receiving cavity. As the adjusting ring slides relative to the rotating disk, the adjusting ring gradually becomes eccentric to the rotating disk. The adjusting ring, through multiple adjusting rods, squeezes and pushes the multiple fan plates, causing each fan plate to deflect at an angle. During the rotation of the rotating disk, the gas flow speed and direction caused by the fan plates within the receiving cavity change. The control component controls the sliding mode of the adjusting ring relative to the rotating disk according to the computer's power-on status, so that the high-speed gas flow generated by the fan plates within the receiving cavity gradually acts on the circuit board, thereby reducing the probability of dust deposition on the circuit board and reducing the probability of circuit board damage.

[0033] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a multi-channel voltage balancing ATX modular power supply for computer hosts, which includes a casing, a fan, an adjustment component, and a control component.

[0034] The housing 110 is hollow inside, and the hollow cavity inside the housing 110 is a receiving cavity 111. The housing 110 can be bolted to the computer case. A circuit board 210 is housed inside the receiving cavity 111. An air inlet 112 is provided on the housing 110, connecting the receiving cavity 111 to the external environment. When the housing 110 is cuboid in shape, the air inlet 112 is located on the upper side wall of the housing 110. An exhaust vent 113 is also provided on the housing 110, connecting the receiving cavity 111 to the external environment. When the housing 110 is cuboid in shape, the exhaust vent 113 is located on the front side wall of the housing 110. Multiple wiring ports are provided on the rear side wall of the housing 110. Each wiring port is electrically connected to the circuit board 210, and each wiring port can be connected to the computer motherboard via a wire, thereby providing power to the computer motherboard. Furthermore, an interface is provided on the front side wall of the housing 110. The interface is electrically connected to the circuit board 210 and is used to connect a power cord, thereby enabling power supply to the circuit board 210.

[0035] The fan includes a rotating disk 120 and multiple fan blades 130. The rotating disk 120 is rotatably disposed in the receiving cavity 111. The axis of the rotating disk 120 is arranged along the front-rear direction of the housing 110. The rotating disk 120 is provided with multiple connecting claws 140, which are evenly distributed around the circumference of the rotating disk 120. The length extension direction of the multiple fan blades 130 is parallel to the axis of the rotating disk 120, and the multiple fan blades 130 are evenly distributed around the circumference of the rotating disk 120. The rotating disk 120 is disposed at the ends of the multiple fan blades 130, and the edge of each fan blade 130 is connected to a connecting claw 140. When the rotating disk 120 rotates, the multiple fan blades 130 rotate synchronously around the axis of the rotating disk 120. When the multiple fan blades 130 rotate around the axis of the rotating disk 120, the multiple fan blades 130 disturb the airflow in the receiving cavity 111.

[0036] The adjusting component includes an adjusting ring 160 and an adjusting rod 150. The adjusting ring 160 abuts against the rotating disk 120 and rotates synchronously with the rotating disk 120. In the initial state, the adjusting ring 160 and the rotating disk 120 are coaxial. Multiple adjusting rods 150 are provided, extending radially along the adjusting ring 160 and evenly distributed around the circumference of the adjusting ring 160. One end of the adjusting rod 150 is rotatably connected to the adjusting ring 160, and the other end is rotatably connected to the middle of one end of the fan plate 130. In the same end of the fan plate 130, the connecting claw 140 and the adjusting rod 150 are spaced apart. The adjusting ring 160 can slide relative to the rotating disk 120. After the adjusting ring 160 slides relative to the rotating disk 120, the adjusting ring 160 gradually becomes eccentric with the rotating disk 120. Under the action of the adjusting rod 150, the fan plate 130 gradually swings around the connecting claw 140. During the rotation of the rotating disk 120, the airflow disturbed by the fan plate 130 in the receiving cavity 111 forms a situation of local wind force increase.

[0037] The control unit controls the sliding mode of the adjusting ring 160 relative to the rotating disk 120 according to the computer's power-on status. Specifically, when the computer is not powered on, the rotating disk 120 is stationary. When the computer is powered on, the control unit controls the rotating disk 120 to start rotating within the receiving cavity 111, and also controls the adjusting ring 160 to slide relative to the rotating disk 120. This causes the fan plate 130 to agitate the air within the receiving cavity 111, creating a localized increase in airflow that flows towards the air inlet 112 on the housing 110, thereby affecting the airflow on the housing 110. The air inlet 112 is back-blown to ensure that the air inlet 112 on the housing 110 is not blocked by dust. After the computer has been turned on for a period of time, the control unit controls the adjustment ring 160 to slide relative to the rotating disk 120, so that the fan plate 130 disturbs the local wind force of the gas in the receiving cavity 111 and directs it toward the circuit board 210 in the receiving cavity 111, thereby sweeping the circuit board 210, changing the boundary layer of the gas acting on the circuit board 210, and reducing the probability of dust deposition on the circuit board 210.

[0038] This invention discloses a multi-channel voltage-balanced ATX modular power supply for computer hosts, comprising a casing, a fan, an adjustment mechanism, and a control mechanism. By configuring the control mechanism, when the computer is powered on, a rotating disk 120 begins to rotate around its own axis. Multiple fan plates 130 mounted on the rotating disk 120 rotate synchronously around the axis of the rotating disk 120. At this time, the multiple fan plates 130 can induce gas flow within the receiving cavity 111. As the adjusting ring 160 slides relative to the rotating disk 120, the adjusting ring 160 gradually becomes eccentric to the rotating disk 120. The adjusting ring 160, through multiple adjusting rods 150, compresses and pushes the multiple fan plates 130. This causes each fan plate 130 to deflect at an angle. During the rotation of the rotating disk 120, the airflow speed and direction caused by the fan plate 130 in the receiving cavity 111 change, causing the fan plate 130 to disturb the air with increased local wind force in the receiving cavity 111. The control unit controls the sliding mode of the adjusting ring 160 relative to the rotating disk 120 according to the computer's power-on status, so that the high-speed airflow formed by the fan plate 130 in the receiving cavity 111 gradually acts on the circuit board 210, thereby reducing the probability of dust deposition on the circuit board 210 and reducing the probability of damage to the circuit board 210.

[0039] In one embodiment, the adjusting component further includes an adjusting cylinder 220, a first connecting ring 170, and a second connecting ring 180. The first connecting ring 170 is fixedly connected to the housing 110 and is coaxially arranged with the rotating disk 120. The first connecting ring 170 has two mounting grooves, each extending radially along the first connecting ring 170, with the two mounting grooves extending perpendicularly to each other. The second connecting ring 180 is coaxially rotatably connected to the adjusting ring 160, thus the second connecting ring 180 can be non-coaxial with the rotating disk 120. Two adjusting cylinders 220 are provided, each fixedly arranged in a mounting groove. The output shafts of both adjusting cylinders 220 are simultaneously rotatably connected to the second connecting ring 180. Initially, the two adjusting cylinders 220 have the same length, so that the second connecting ring 180 and the adjusting ring 160 are simultaneously in a state of coaxial rotation with the rotating disk 120. The control unit can control the length of the two regulating cylinders 220. When the length of the regulating cylinder 220 increases, the second connecting ring 180 drives the regulating ring 160 to gradually become non-axial with the rotating disk 120. Furthermore, the regulating ring 160 drives multiple regulating rods 150 to adjust the angle of multiple fan plates 130. Then, when the rotating disk 120 rotates, the fan plates 130 disturb the gas with increased local wind force in the receiving cavity 111.

[0040] In one embodiment, the regulating cylinder 220 is an electrically controlled telescopic cylinder. The controller can independently control any one of the electrically controlled telescopic cylinders. The controller can precisely control the deflection angle of the fan plate 130 on the rotating disk 120. During the rotation of the rotating disk 120, the fan plate 130 disturbs the air in the receiving cavity 111, which increases the local wind force and can be directed toward the air inlet 112 on the housing 110 or the circuit board 210. When sweeping the air inlet 112 on the housing 110, it is ensured that the air inlet 112 on the housing 110 is not blocked by dust. When sweeping the circuit board 210, the boundary layer of the gas acting on the circuit board 210 is changed, reducing the probability of dust deposition on the circuit board 210.

[0041] In one embodiment, the housing 110 is equipped with a drive motor 190, which is fixedly connected to the housing 110. The power output shaft of the drive motor 190 is coaxially fixedly connected to the rotating disk 120. When the drive motor 190 starts, it can drive the rotating disk 120 to rotate. The drive motor 190 is electrically connected to the circuit board 210 through wires. The control unit can control the drive motor 190 to rotate at a constant speed. When the computer is turned on, the drive motor 190 starts synchronously. After the drive motor 190 runs smoothly, it rotates at a constant speed, driving the rotating disk 120 to rotate at a constant speed.

[0042] In one embodiment, the drive motor 190 has a start / stop button. When the drive motor 190 needs to be started, the operator can press the start / stop button. To ensure that the computer power-on and the drive motor 190 start synchronously, the start / stop button of the drive motor 190 is integrated into the computer's power button, so that the start / stop button is the same as the computer's power button. When the computer and drive motor 190 need to be started, the operator only needs to press the computer's power button.

[0043] In one embodiment, the control component is a control board integrated into the circuit board 210. The control board contains a control program that controls the length change of the regulating cylinder 220 according to the computer's power-on status. Specifically, the control program includes the following steps:

[0044] When the computer starts up, the control program controls the two regulating cylinders 220 to change length in a first preset manner. Specifically, when the computer is not started, the components on the circuit board 210 are at room temperature. When the computer starts up, the components on the circuit board 210 gradually start working, causing the temperature of the circuit board 210 to gradually rise. In the initial stage of computer startup, the circuit board 210 does not need to be cooled down. At this time, the control program controls the two regulating cylinders 220 to extend in the first preset manner. At this time, the regulating ring 160 slides relative to the rotating disk 120, and the fan plate 130 agitates the air in the receiving cavity 111, causing the local wind force to increase and move towards the air inlet 112 on the housing 110, thereby backflushing and cleaning the air inlet 112 on the housing 110 to ensure that the air inlet 112 on the housing 110 is not blocked by dust.

[0045] After the computer runs for a preset period of time, the control program controls the two regulating cylinders 220 to change length in a second preset manner. Specifically, after the computer runs for a preset period of time, the temperature of the components on the circuit board 210 rises to a high temperature. At this time, it is necessary to cool down the components on the circuit board 210. The control program controls the two regulating cylinders 220 to extend in the second preset manner. At this time, the regulating ring 160 slides relative to the rotating disk 120, and the fan plate 130 agitates the gas with increased local wind force in the receiving cavity 111 towards the circuit board 210. During the rotation of the rotating disk 120, the fan plate 130 agitates the gas with increased local wind force in the receiving cavity 111, gradually sweeping the circuit board 210, changing the boundary layer of the gas acting on the circuit board 210, and reducing the probability of dust deposition on the circuit board 210.

[0046] In one embodiment, the first preset method is to control the two regulating cylinders 220 to extend simultaneously, and after the two regulating cylinders 220 extend, the deflection angle of the fan plate 130 near the air inlet 112 is greater than the deflection angle of the fan plate 130 far away from the air inlet 112. Then, when the rotating disk 120 rotates, the fan plate 130 gradually sweeps the air inlet 112.

[0047] Furthermore, the second preset method is to control the two regulating cylinders 220 to extend simultaneously, and after the two regulating cylinders 220 extend, the deflection angle of the fan plate 130 near the circuit board 210 is greater than the deflection angle of the fan plate 130 far away from the circuit board 210. Then, when the rotating disk 120 rotates, the fan plate 130 gradually sweeps the circuit board 210.

[0048] In one embodiment, the control program includes a timer that activates after a preset time period of computer operation, switching the length change mode of the two regulating cylinders 220 from a first preset mode to a second preset mode. Figure 8 As shown, the first switch is the computer's start button. When the computer's start button is closed, the first signal source receives a current signal, while the third signal source does not receive a current signal due to the delay timer. The control program controls the two regulating cylinders 220 to change length in a first preset manner based on the current signal from the first signal source. After the delay timer reaches the preset delay time, the third signal source receives a current signal. At this time, the control program controls the second switch to close. After the second switch is closed, the second signal source receives a current signal, and the control program controls the two regulating cylinders 220 to change length in a second preset manner based on the current signal from the second signal source.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
