Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the computer self-dedusting radiator comprises a heat conduction base 1, heat pipes 2 are uniformly distributed on the heat conduction base 1 along the circumferential direction, heat dissipation fins 3 are uniformly distributed on the heat conduction base 1 from top to bottom, and the heat dissipation fins 3 are annular; the upper part of the heat pipe 2 sequentially penetrates through the outer sides of the radiating fins 3 and is fixed with the radiating fins 3; the upper end of the heat conduction base 1 is provided with a driving motor 4; the output end of the driving motor 4 is vertically upward and is coaxially connected with a central shaft 6 through an elastic supporting seat 5; the elastic supporting seat 5 comprises a sleeve 7 which is fixedly sleeved at the output end of the driving motor 4; a spring 8 is arranged in the sleeve 7; the lower end of the central shaft 6 is sleeved in the sleeve 7 in a sliding manner; the lower end of the central shaft 6 is connected with the output end of the driving motor 4 through a spring 8; the radiating fins 3 are coaxially arranged outside the central shaft 6; a heat dissipation and dust removal device is arranged between every two adjacent heat dissipation fins 3;
the heat dissipation dust removal device comprises a radial flow impeller 9 arranged in the middle of two adjacent heat dissipation fins 3; the radial flow impeller 9 comprises a mounting ring 10 coaxially arranged outside the central shaft 6; radial flow blades 11 are uniformly distributed on the outer side of the mounting ring 10 along the circumferential direction; the outer diameter of the mounting ring 10 is smaller than the inner diameter of the radiating fins 3; the inner side of the mounting ring 10 is fixedly sleeved with the central shaft 6 through a connecting frame 12; the driving motor 4 is fixed on the heat conduction base 1 through a heat insulation cushion pad 13; the upper side of the heat dissipation fin 3 at the uppermost end is fixed with a guide frame 14; the guide frame 14 is correspondingly sleeved outside the central shaft 6; the surface of the radial flow blade 11 is coated with a Teflon coating; the upper end of the central shaft 6 is fixedly sleeved with an axial flow impeller 15; the driving motor 4 is a forward and reverse rotating motor.
In the technical scheme, a runoff impeller 9 is arranged between every two adjacent radiating fins 3, so that the radiating fins 3 and the runoff impeller 9 are sequentially and alternately installed in the production and assembly process, in addition, in order to ensure that the inner ring space of the radiating fins 3 is not blocked by the connecting frame 12 too much, the angle directions of all the connecting frames 12 during installation are preferably kept consistent, so that the clamping pins 16 which are uniformly distributed can be arranged on the upper side of the installing ring 10 fixed with the connecting frame 12, and the clamping grooves 17 which correspond to the clamping pins one to one can be arranged on the lower side of the installing ring, as shown in fig. 2, so that the angle directions of all the connecting frames 12 can be ensured to be consistent after the runoff impeller 9 is connected through the clamping pins 16 and the clamping grooves 17.
After the radiator is installed, when the computer works, the driving motor 4 can be started (the driving motor 4 is powered by the computer host), and the central shaft 6 can drive all the runoff impellers 9 to rotate (the runoff impellers 9 are not in contact with the radiating fins 3 at the moment), so that the air blowing and the heat dissipation are realized. In the process, the rotation of the radial flow impeller 9 not only plays a role of heat dissipation, but also can slow down the accumulation of dust on the surface of the heat dissipation fins 3 due to the outward radial flow wind direction generated when the radial flow impeller 9 rotates.
When the surface of the radiating fin 3 needs to be dedusted, the radiator does not need to be dismounted, and only the central shaft 6 needs to be moved downwards (at the moment, the spring 8 is compressed in the sleeve 7), so that the radial flow blade 11 can be contacted with the upper end surface of the radiating fin 3 adjacent to the lower side, the dust can be swept away through the rotation of the radial flow blade 11, and the dust is blown away outwards through the radial flow wind direction; similarly, by moving the central shaft 6 upward (the spring 8 is stretched in the sleeve 7), the radial flow blade 11 can be brought into contact with the lower end surface of the upper adjacent heat radiation fin 3, and dust can be removed by the radial flow blade 11. In order to increase the strength of the radial flow vanes 11, the outer ends of the radial flow vanes 11 may be connected using the fixing ring 18.
Above-mentioned center pin 6's removal can be realized through manual pressing or pulling center pin 6, but the operation is convenient inadequately, consequently in order to improve the dust removal convenience, among this technical scheme, fixed axial compressor impeller 15 on center pin 6, the certain degree is accelerated to the 15 rotational speeds of axial compressor impeller, can produce powerful wind pressure, and rethread driving motor 4's positive and negative rotation switches, and powerful wind pressure can drive center pin 6 and move up or move down, need not the manual pressure again. In addition, the axial flow impeller 15 can blow air downwards along the space of the inner ring of the radiating fins 3, so that the air inlet amount is increased, and the air blowing and heat radiating effect of the radial flow impeller 9 is improved.
In the technical scheme, the working mode of the radiator is set into a heat radiation mode and a dust removal mode. During daily work, the radiator is set to be in a radiating mode, the rotating direction of the driving motor 4 cannot be switched at the moment, the axial flow impeller 15 keeps a downward blowing state, the maximum rotating speed of the driving motor 4 is limited, and thrust force caused by wind pressure of the axial flow impeller 15 is not enough to enable the radial flow blades 11 to be in contact with the radiating fins 3, so that the radiator can keep low noise during daily use of the computer; when dust removal is needed, the working mode of the radiator is switched to the dust removal mode, the rotation direction of the driving motor 4 can be switched at the moment, the rotation speed of the driving motor 4 can break through the maximum rotation speed in the heat removal mode, the thrust caused by the wind pressure of the axial flow impeller 15 can be increased to the degree that the radial flow blades 11 are in contact with the heat dissipation fins 3, the dust removal on the surfaces of the heat dissipation fins 3 is achieved, the rotation speed of the radial flow impeller 9 is accelerated at the moment, and the dust removal efficiency is high.
The switching between the heat dissipation mode and the dust removal mode is to control the rotation speed and the rotation direction of the driving motor 4, the rotation speed adjustment of the driving motor 4 can be realized by changing the voltage, the rotation direction of the driving motor 4 can be realized by exchanging the positive electrode and the negative electrode of the power supply, and the adjustment processes can be set by system software such as bios of the main board, which belongs to the prior art and is not described in detail in the technical scheme.
