Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-5, a dustproof cooling type power supply includes a protective housing 1, a power supply device is installed in the protective housing 1, and the composition and installation manner of each component of the power supply device are the same as those of the existing power supply, which is not related to the design purpose of the present solution and will not be described in detail.
The top has seted up dust storage tank 21 in the air intake 2, and inlays on the inner wall of dust storage tank 21 and be equipped with the glass board, and the sealed sliding connection has sliding plug 11 in the dust storage tank 21, and sliding plug 11's upper end is equipped with silk layer 111, and the end setting of giving vent to anger of rubber hose 7 is at the interior bottom in dust storage tank 21.
As shown in fig. 1, under the action of the fan inside the power supply, the airflow flows through the power supply as shown by the arrow, and the dust in the air will gradually gather on the dust screen 4 at the air inlet 2.
In the process, the air flow pushes the impeller 5 to rotate, and simultaneously drives the baffle 8 to rotate together, and the baffle 8 intermittently blocks the negative pressure hole 61. When the baffle plate 8 does not block the negative pressure hole 61, the air flow in the protective shell 1 is fast, the generated pressure is small, and the air flow in the air groove 6 communicated with the interior of the protective shell 1 is slow, the pressure is large, so that the air pressure difference can be generated between the air groove 6 and the protective shell 1, and the elastic sheet 9 is forced to deflect downwards. When the baffle 8 blocks the negative pressure hole 61, the airflow does not pass through the negative pressure hole 61 any more, so that the air pressure difference between the air tank 6 and the protective shell 1 disappears, and the elastic sheet 9 deflects upwards under the action of the elasticity of the elastic sheet.
And because the air flow velocity is fast, so the rotational speed of impeller 5 and baffle 8 is also fast, the frequency that baffle 8 blocks negative pressure hole 61 is higher, so the frequency that shell fragment 9 squints from top to bottom is also higher. In the process of high-frequency up-and-down deviation of the elastic sheet 9, when the elastic sheet 9 deviates upwards, air above the elastic sheet 9 can be instantly squeezed into the rubber hose 7, and because the pipe diameter of the rubber hose 7 is small, the air in the pipe cannot be exhausted in time, so that the air expands, then contracts and recovers under the action of the elasticity of the air, and the air is exhausted from the dust storage groove 21 to force the sliding plug 11 to move upwards; when the elastic sheet 9 is deflected downwards, air can be pumped back into the air groove 6, and the sliding plug 11 is also moved downwards. Therefore, in the heat dissipation process of the power supply, the rubber hoses 7 are continuously expanded and contracted, so that the dust screen 4 at the air inlet 2 is continuously shaken, dust attached to the dust screen 4 can be shaken off in time, and the dust is prevented from being gathered on the dust screen 4 to influence the heat dissipation effect of the power supply. In addition, in the process that the sliding plug 11 moves up and down, the silk layer 111 at the upper end of the sliding plug 11 can continuously rub the glass plate on the inner wall of the dust storage groove 21, so that static electricity can be generated on the surface of the glass plate, shaken off dust can be adsorbed on the glass plate, the shaken off dust can be prevented from being blown onto the dust screen 4 again by subsequent air flow, and the dust prevention effect of the device is improved.
Example two:
referring to fig. 6, the difference from the first embodiment is that the inner bottom of the protective shell 1 is provided with a strip-shaped groove 12, the inner bottom of the strip-shaped groove 12 is provided with an air hole 121, the inner wall of the strip-shaped groove 12 is fixedly connected with a telescopic airbag 10, the telescopic airbag 10 is filled with a cooling liquid, and the liquid outlet end of the telescopic airbag 10 is fixedly connected with a sliding block 101. The air hole 121 at the bottom of the strip-shaped groove 12 can facilitate the slider 101 to move left and right back and forth without being blocked by air.
The slider 101 is connected in the strip groove 12 in a sealing and sliding manner, and the strip groove 12 is communicated with the dust storage groove 21 through the air duct 15, the rubber hose 7 is communicated with the inside of the telescopic airbag 10, the rubber hose 7 is internally provided with the first check valve 71, the telescopic airbag 10 is communicated with the air groove 6 through the liquid return pipe 13, and the liquid return pipe 13 is internally provided with the second check valve 131.
The first check valve 71 allows the coolant to flow only from the air tank 6 into the air bag 10, and the second check valve 131 allows the coolant to flow only from the air bag 10 into the air tank 6. And the communicating part of the liquid return pipe 13 and the air groove 6 is arranged at the inner bottom of the air groove 6.
In this embodiment, when the elastic sheet 9 is deflected downward, the sealed space above the elastic sheet 9 is increased to generate negative pressure to draw the coolant in the air bag 10 into the air tank 6 through the liquid return pipe 13, and at this time, the air bag 10 is contracted to pull the slider 101 to move left. When the elastic sheet 9 is deflected upwards, the pumped cooling liquid can be instantly squeezed into the telescopic air bag 10 along the rubber hose 7, the rubber hose 7 can also be caused to expand, the dust screen 4 can be shaken to shake off dust attached to the dust screen, and the telescopic air bag 10 can be expanded after the cooling liquid enters the telescopic air bag 10, and the sliding block 101 is pushed to move to the right.
Meanwhile, the cooling liquid flowing along the rubber hose 7 and the liquid return pipe 13 in a one-way circulating manner can quickly dissipate heat generated during the operation of the power supply, so that the heat dissipation effect of the power supply is greatly improved. The sliding block 101 moves left and right well, and can also push the sliding plug 11 to move up and down in the dust storage groove 21, so that the silk layer 111 and the glass plate rub to generate static electricity and adsorb falling dust. It is worth mentioning that the liquid return pipe 13 and the rubber hose 7 disposed in the protective casing 1 are blown by the high-speed airflow, so that the cooling liquid in the pipe can be kept in a low temperature state, and the heat dissipation process can be continuously performed on the power supply.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
