Description

Technical Field

[0001] The invention relates to the technical field of a quick-detachable hard disk rack with a heat dissipation function, and in particular to a quick-detachable hard disk rack with a heat dissipation function. Background Art

[0002] A hard drive rack is a structure used to install hard drives. It is usually composed of an independent bracket that is directly connected to the hard drive and a hard drive box that can be directly and synchronously inserted into multiple hard drives. During use, hard drives can be added or removed according to storage needs. It is usually used in environments such as server base stations with large storage capacities.

[0003] Hard disks are prone to generate heat when storing, especially large-capacity storage, and it is difficult to discharge and exchange heat in a computer room environment. Therefore, it is easy to generate a lot of heat in the hard disk box, and the heat can easily cause the circuit board and plastic parts in the hard disk to deform, thereby causing damage to the hard disk. The existing hard disk rack heat dissipation structure is mostly on one side of the hard disk independent bracket, and the hard disk heat is mostly generated on the upper and lower sides of the hard disk with larger areas. Therefore, the heat dissipation effect of the existing heat dissipation structure is not ideal. Therefore, a quick-disassembly and assembly hard disk rack with heat dissipation function is proposed to solve the above-mentioned problems. Summary of the invention

[0050] The electromagnet 5 can switch the magnetic pole by changing the direction of the current. The electromagnet 5 switches the magnetic pole by pressing and popping up the annular button 407.

[0051] The electromagnet 5 has the functions of cutting off the magnetic force when the power is turned off, and changing the direction of the current to switch the electrodes. It can improve the firmness of the hard disk insertion by the attraction of opposite charges when inserting, and can also make a part of the hard disk pop out to provide a gripping position for removal by the principle of repulsion of like charges when removing, so as to achieve a more convenient operation effect;

[0054] A reinforcing rib is provided between the connecting rod 404 and the pressing block 405, and a sliding rod 17 fixedly connected to the top wall and the bottom wall of the inner cavity of the pressing cavity 15 is slidably connected inside the pressing block 405, and the sliding rod 17 is located on the inner side of the annular button 407 and the protrusion 406, and a silicone pad arranged in an annular shape is fixedly connected to the bottom of the protrusion 406, and the top of the left side of the pressing block 405 is inclined, and the left side of the pressing cavity 15 is arranged in an arc shape;

[0055] The left side of the pressing cavity 15 is arranged in an arc shape to facilitate the insertion of fingers during operation, which is more ergonomically designed;

[0056] The back side of the block 206 is tilted, the front side of the limit block 401 is tilted, the block 206 and the limit block 401 are adapted to each other, the filter box 601 includes a box body 6011, the bottom of the box body 6011 is hollowed out, the outer side of the box body 6011 is connected to the inner thread of the air guide cavity 9 and the top surface protrudes from the top surface of the hard disk case 1, the interior of the box body 6011 is filled with a replaceable filter layer 6012, the inner side of the box body 6011 is connected to a cover plate 6013 by threads, the top surface of the cover plate 6013 is higher than the top surface of the box body 6011, the top of the cover plate 6013 is hollowed out, the right inner diameter of the air guide groove 604 is larger than the left inner diameter, the air guide groove 604 is located above the right guide plate 603 on the same side, and the air guide groove 604 is adapted to the guide direction of the left guide plate 602 on the same side;

[0057] The left guide plate 602, the right guide plate 603 and the air guide groove 604 cooperate with each other to guide part of the external wind through the left guide plate 602 and into the placement cavity 8 through the air guide groove 604, and the wind that has not entered can continue to be guided to the right through the right guide plate 603 into the lower layer, and the cycle is repeated, so that a large amount of wind can enter the placement cavities 8 of different layers to dissipate heat for the hard disk body 3.

[0058] Working principle:

[0059] During normal use:

[0060] First, the hard disk body 3 will generate a certain amount of heat due to the reading and writing operations, and the air intake fan 605 is started during the reading and writing process. The air intake fan 605 filters the dust from the outside air through the filter box 601 and then guides it into the air guide cavity 9. After the air enters the air guide cavity 9, it first guides most of the air to the left through the left guide plate 602. A part of the wind moving to the left is guided to the placement cavity 8 of the same layer through the air guide groove 604. The wind that does not enter the placement cavity 8 of this layer continues to flow downward and is guided to the right through the right guide plate 603 to avoid the problem that the wind is generated vertically downward, so that the heat dissipation effect of the lower layer is not as good as that of the upper layer. The wind guided to the right hits the right side wall of the inner cavity of the air guide cavity 9 and rebounds to the left guide plate 602 of the lower layer to repeat the operation of the upper layer.

[0061] Secondly, after the external wind is introduced into the placement chamber 8, it first continues to pass through the air hole 12, and then is introduced under the drainage fin 203. At this time, due to the leftward tilt of the drainage fin 203, the wind can continue to be diverted to the left, so that the flow rate of the wind below the drainage fin 203 is greater than the flow rate above the drainage fin 203, so that a pressure difference is generated, and then the hot air above the air permeable plate 202 is attracted downward through the heat dissipation hole 13, and continues to flow to the left so that it passes through the left air hole 12 and the exhaust hole 10 in turn and is discharged to the outside of the hard disk box 1;

[0062] When the hard disk body 3 needs to be replaced or removed:

[0063] First, press the pressing block 405 to make it slide down in the pressing chamber 15, and drive the extension rod 402 to press down via the connecting rod 404, and the downward pressure of the extension rod 402 can link the limit block 401 to press down and shrink into the compression chamber 16, and make it disengage from the block 206. When the pressing block 405 is pressed down to the lowest end, the protrusion 406 contacts the annular button 407 and presses the annular button 407. At this time, the annular button 407 transmits an electrical signal to the electromagnet 5 to switch the magnetic poles of the electromagnet 5, so that its magnetic poles are the same as the magnetic poles of the magnetic block 207 to generate a repulsive force, and the hard disk rack 2 is pushed by the repulsive force between the magnetic poles. During the pushing process, the dustproof door plate 18 is squeezed open by the shell 201, and the hard disk rack 2 and the hard disk can be taken out and replaced;

[0064] Secondly, when insertion is required, one only needs to manually lift up the dustproof door panel 18 and insert the hard disk rack 2 into the placement cavity 8. At this time, the clamping block 206 can clamp the hard disk rack 2 through the matching limit block 401, and during the insertion process, since the electromagnet 5 does not receive the pressing signal of the annular button 407, the magnetic pole and the magnetic block 207 are attracted by opposite sexes. Therefore, after manually inserting a certain distance, the electromagnet 5 will naturally welcome the hard disk rack 2 to be automatically inserted into the placement cavity 8, and the dustproof door panel 18 will close naturally due to gravity.
