Description

Technical Field

[0001] The present invention relates to the technical field of computers, and in particular to a ventilation and heat dissipation device for a computer. Background Art

[0002] The shell of the host is generally called the chassis. As a part of computer accessories, the chassis mainly plays the role of placing and fixing various computer accessories, and plays a supporting and protective role. In addition, the computer chassis plays an important role in shielding electromagnetic radiation. Since the chassis cannot quickly improve the performance of the whole machine like CPU, graphics card, motherboard and other accessories, it has not been listed as a key consideration in DIY. However, the chassis is not useless. After some users bought a no-name chassis, the motherboard and the chassis formed a loop, resulting in a short circuit, making the system very unstable.

[0003] The main operating hardware facilities of the computer equipment are installed in the main chassis, and the main chassis generally includes a chassis with one side open, wherein a side panel for sealing the open end of the chassis is provided, and heat dissipation holes are evenly provided on the side panel for heat dissipation and air circulation in the chassis. However, after long-term use, dust will accumulate on the inner and outer walls of the side panel in the heat dissipation hole area, thereby affecting the use of the computer. The cleaning method is generally to remove the side panel, but due to the large size of the side panel, firstly, it is easy to make disassembly and installation inconvenient, and secondly, since one side of the chassis is completely open, it is easy to cause damage to the internal components of the chassis during subsequent operations. Summary of the invention

[0004] The purpose of the present invention is to provide a computer ventilation and heat dissipation device.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A computer ventilation and heat dissipation device comprises a chassis with one side open, wherein a side plate for sealing the open end of the chassis is provided at the open end:

[0007] The side plate is provided with an installation opening, wherein a rectangular cylinder with two ends open is provided in the installation opening, one end of the cylinder is provided with a folded edge located outside the side plate, wherein the other end of the cylinder extends into the chassis, a locking mechanism and a filtering mechanism are sequentially provided in the cylinder, and screws are threadedly connected in the cylinders on both sides of the filtering mechanism;

[0008] The locking mechanism comprises a forward and reverse screw rod radially arranged in the cylinder, wherein both ends of the forward and reverse screw rod are fixed to the inner wall of the cylinder through rolling bearings, and both ends of the forward and reverse screw rod are provided with nuts, and one end of the nut is provided with a limit rod which penetrates the side wall of the cylinder and extends to the inner side of the side plate;

[0009] The filtering mechanism includes two groups of filter screens arranged in parallel, wherein the top of the filter screen is hinged to the top wall of the cylinder body through a hinge, and the two groups of filter screens are connected by a spring, and a slag discharge port located between the two groups of filter screens is provided on the bottom wall of the cylinder, wherein a sealing plug is provided at the slag discharge port.

[0010] Preferably, the size of the cylinder is adapted to the size of the installation opening, wherein a through hole is provided on the side wall of the cylinder for the limiting rod to pass through, and a protrusion is provided at the end of the limiting rod to abut against the inner wall of the side plate, wherein a circle of expansion grooves for accommodating the protrusion is provided on the outer wall of the cylinder outside the through hole.

[0011] Preferably, a driving part is provided in the middle of the forward and reverse screw rods.

[0012] Preferably, the filter screen abuts against one side of the corresponding screw rod, and screw holes for being screwed to the screw rod are provided on both side walls of the cylinder.

[0014] Preferably, a support block for supporting the bottom of the cylinder is arranged on the inner wall of the side plate below the installation opening, wherein the support plate and the locking mechanism are staggered.

[0015] The beneficial effects of the present invention are as follows: in the present invention, the airflow is filtered at multiple stages through two groups of filters to prevent impurities from entering the chassis, and the filtered airflow can effectively cool down the components in the chassis. At the same time, when impurities such as dust accumulate on the filter, the cylinder can be removed from the installation opening by disassembling the locking mechanism, and the impurities on its end surface can be manually cleaned, or the filter can be pressed to compress the spring while rotating with the hinge as the center of the circle, and then the filter is released and reset under the pushing force of the spring expansion and collides with the screw, thereby shaking off the impurities on its end surface, and finally the impurities are discharged through the opened slag discharge port. Since the above-mentioned components are small and can be easily disassembled and installed without the aid of professional tools, the difficulty is effectively reduced and it is not easy to cause damage to the components in the chassis.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] A computer ventilation and heat dissipation device comprises a case 1 with one side open, wherein a side plate 2 is provided at the open end of the case 1 to seal the open end.

[0022] The side plate 2 is provided with an installation opening 3, wherein a rectangular cylinder 4 with both ends open is provided in the installation opening 3, one end of the cylinder 4 is provided with a folded edge 5 located outside the side plate 2, wherein the other end of the cylinder 4 extends into the chassis 1, and a locking mechanism 6 and a filtering mechanism 7 are sequentially provided in the cylinder 4, and screws 8 are screwed in the cylinder 4 on both sides of the filtering mechanism 7;

[0023] The locking mechanism 6 comprises a forward and reverse screw rod 61 radially arranged in the cylinder 4, wherein both ends of the forward and reverse screw rod 61 are fixed to the inner wall of the cylinder 4 through rolling bearings, and both ends of the forward and reverse screw rod 61 are provided with nuts 62, and one end of the nut 62 is provided with a limit rod 63 that penetrates the side wall of the cylinder 4 and extends to the inner side of the side plate 2;

[0024] The filtering mechanism 7 includes two groups of filter screens 71 arranged in parallel, wherein the top ends of the filter screens 71 are hinged to the inner top wall of the cylinder 4 through hinges, and the two groups of filter screens 71 are connected by springs 72, and a slag discharge port 9 located between the two groups of filter screens 71 is provided on the bottom wall of the cylinder 4, wherein a sealing plug 10 is provided at the slag discharge port 9.

[0025] like Figure 3 As shown, the size of the cylinder 4 is adapted to the size of the installation opening 3, wherein a through hole 11 for the limiting rod 63 to pass through is opened on the side wall of the cylinder 4, and a protrusion 12 that abuts against the inner wall of the side plate 2 is arranged at the end of the limiting rod 63, wherein a circle of expansion grooves 13 that can accommodate the protrusion 12 is arranged on the outer wall of the cylinder 4 outside the through hole 11.

[0026] In this embodiment, a driving part is arranged in the middle of the forward and reverse screw rods 61. The driving part facilitates the rotation of the forward and reverse screw rods 61.

[0027] In this embodiment, the filter screen 71 abuts against one side of the corresponding screw rod 8 , and screw holes for screwing with the screw rod 8 are provided on the two side walls of the cylinder body 4 .

[0028] In this embodiment, a magnetic connection layer magnetically connected to the side plate 2 is provided on one side wall of the folded edge 5 .

[0029] In this embodiment, a support block for supporting the bottom of the cylinder 4 is arranged on the inner wall of the side plate 2 below the installation opening 3, wherein the support plate is staggered with the locking mechanism 6. The support block supports the cylinder 4 to improve its stability.

[0030] The working principle of the present invention is as follows: after the cylinder 4 is removed into the installation opening 3, the nut 62 is driven to move outward by rotating the forward and reverse screw rods 61, thereby driving the limiting rod 63 to slide in the through hole 11, and at the same time, the limiting rod 63 drives the protrusion 12 to slide out of the expansion groove 13 and abut against the inner wall of the side plate 2, so that the cylinder 4 is prevented from sliding out of the installation opening 3 by clamping the side wall of the side plate 2 with the folding edge 5 and the protrusion 12;

[0031] The gas flows through the apertures of the two sets of filter screens 71 in the cylinder 4, thereby performing multi-stage filtration on the gas. When the filter screen 71 needs to be thoroughly cleaned, it is only necessary to rotate the forward and reverse screw rods 61 to drive the nut 62 to move inward, thereby driving the limit rod 63 to slide in the through hole 11, and at the same time, the limit rod 63 drives the protrusion 12 to slide into the expansion groove 13, and at this time, the cylinder 4 can be easily taken out from the installation opening 3;

[0032] In the above process, since the diameter of the protrusion 12 is larger than the inner diameter of the through hole 11, the protrusion 12 is prevented from sliding into the cylinder 4. When the cylinder 4 is taken out and cleaned, the filter screen 71 can be pressed to compress the spring 72 while rotating around the hinge. Then, the filter screen 71 is released and reset under the pushing force of the spring 72 and collides with the screw 8, thereby shaking off the impurities on its end surface, or the impurities on the filter screen 71 can be manually cleaned and finally discharged through the opened slag discharge port 9.

[0033] In the present invention, two groups of filters 71 are used to perform multi-stage filtration on the airflow to prevent impurities from entering the chassis 1, and the filtered airflow can effectively cool down the components in the chassis 1. At the same time, when impurities such as dust accumulate on the filter 71, the cylinder 4 can be removed from the installation opening 3 by disassembling the locking mechanism 6, and the impurities on its end surface can be manually cleaned, or the filter 71 can be pressed to compress the spring 72 while rotating it with the hinge as the center of the circle, and then the filter 71 is released and reset under the pushing force of the spring 72 and collides with the screw 8, thereby shaking off the impurities on its end surface, and finally the impurities are discharged through the opened slag discharge port 9. Since the above-mentioned components are small and can be easily disassembled and installed without the aid of professional tools, the difficulty is effectively reduced and it is not easy to cause damage to the components in the chassis 1.

[0034] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
