Description

Technical Field

[0001] This utility model relates to the field of computer case technology, specifically to a computer case with efficient heat dissipation. Background Art

[0002] A computer, commonly known as a PC, is a modern intelligent electronic device that can run according to a program and automatically and quickly process massive amounts of data. The computer host refers to the main body of the computer excluding input and output devices, and is also the control box used to house the motherboard, CPU, memory, optical drive, power supply, etc.

[0003] When computer components such as the CPU are running under high load, they generate a lot of heat. The computer case needs to dissipate heat quickly and effectively. However, most computer cases nowadays dissipate heat directly through a combination of cooling fans and local ventilation holes. In order to prevent a large amount of dust or small insects from entering the computer case, the ventilation holes are generally designed to be small. After long-term use, dust inevitably accumulates on the dust filters inside the ventilation holes, causing the ventilation holes to become blocked and the heat cannot be dissipated in time. This leads to an increase in the temperature inside the computer case, which may affect the operation of the computer. When it is necessary to disassemble and assemble the internal components of the computer case, since the removable panels on the outside of the computer case are installed and fixed with small screws, it is not only time-consuming and laborious to operate, but also the repeated tightening of screws may cause stripping problems, making it impossible to install the removable panels.

[0004] Therefore, it is of great importance to design a computer case with efficient heat dissipation to solve the above-mentioned defects. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model designs a computer chassis with high-efficiency heat dissipation. This high-efficiency heat dissipation computer chassis aims to solve the problems of dust accumulation on the dust filters inside the ventilation holes of existing computer chassis after prolonged use, which leads to blockage of the ventilation holes and prevents heat from being dissipated in a timely and rapid manner. This results in an increase in the temperature inside the chassis, which may affect the operation of the computer. Furthermore, when it is necessary to disassemble and assemble the internal components of the chassis, the operation is not only time-consuming and laborious, but repeated tightening of screws may also cause stripping, thus making it impossible to install removable boards.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-efficiency heat dissipation computer case includes a case shell, with multiple sets of ventilation holes on the front of the case shell, cooling fans fixedly installed at the top and bottom ends of the back of the case shell, a kick plate fixedly installed at the bottom of the front of the case shell, and a removable plate slidably connected to the right side of the case shell. The front and rear ends of the top of the removable plate are fixedly connected to the case shell via fixing cylinders. The case also includes:

[0008] A dust removal assembly is fixedly installed on the front end of the top of the chassis shell, and the dust removal assembly is used to remove dust from the back of the ventilation holes.

[0009] As a preferred embodiment of this utility model, a transparent glass plate is fixedly installed on the left side of the chassis shell, and support pads are fixedly connected to the four corners of the bottom of the chassis shell.

[0010] As a preferred embodiment of this utility model, a dust collection box is slidably connected to the front of the chassis shell and below the multiple sets of ventilation holes. A pull-out groove is provided on the front of the dust collection box. A dustproof net is fixedly installed inside the chassis shell and inside the multiple sets of ventilation holes.

[0011] As a preferred embodiment of this utility model, the four corners of the front of the chassis shell and located inside the kick plate are all fixedly connected with connecting posts. Sliding sleeves are slidably connected to the outer sides of multiple sets of connecting posts. A connecting rod is installed between the sliding sleeve and the kick plate, and the two ends of the connecting rod are rotatably connected to the sliding sleeve and the kick plate, respectively. A first spring is sleeved on the outer side of the connecting post and on the side of the sliding sleeve away from the connecting rod.

[0012] As a preferred embodiment of this utility model, the upper and lower ends of the inner side of the detachable plate are slidably connected to the outer casing of the chassis via connecting edges, and multiple sets of protruding strips are fixedly connected to the front end of the outer side of the detachable plate.

[0013] As a preferred embodiment of this utility model, a fixing post is slidably connected inside the fixing cylinder, a limiting ring is fixedly connected inside the fixing cylinder and outside the fixing post, a second spring is sleeved on the outside of the fixing post and at the top of the limiting ring, and a fixing hole adapted to the fixing post is opened inside the connecting edge.

[0014] As a preferred embodiment of this utility model, the dust removal assembly includes a drive box fixedly installed on the top front end of the chassis shell. An air guide pipe is fixedly installed on the back of the drive box. A rotating shaft is rotatably connected to the top of the drive box. A turntable is fixedly connected to the front end of the rotating shaft and inside the drive box. An impeller is fixedly connected to the rear end of the rotating shaft and inside the air guide pipe. A swing arm is rotatably connected to the drive box and below the turntable. The front of the turntable is slidably connected to the swing arm via a sliding column. A sliding rod is slidably connected to the bottom of the drive box. The bottom end of the swing arm engages with the outer side of the sliding rod. Multiple brush plates are fixedly connected to the outer side of the sliding rod and behind multiple sets of ventilation holes.

[0015] As a preferred embodiment of this utility model, an air guide cover is fixedly installed on the top of the air guide duct, a filter frame is slidably connected to the front of the air guide cover, and a filter screen is fixedly installed on the inner side of the filter frame.

[0016] As a preferred embodiment of this utility model, the top end of the swing arm is slidably connected to the sliding column via a guide groove, and both ends of the sliding rod are slidably connected to the drive box via connecting seats. Multiple sets of flexible bristles are fixedly connected to the front of the brush plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this utility model, through the coordinated design of the chassis shell, ventilation holes, cooling fan, and dust removal components, when the chassis shell is in use, the cooling fan is activated to draw in external air through the ventilation holes by exhausting air outwards. The dust filter prevents dust in the air from entering the interior of the chassis shell. Subsequently, the cooling fan expels heat from inside the chassis shell. When the cooling fan is working, some air enters through the air duct under the action of suction. When the air enters the interior of the air duct, the impeller drives the rotating shaft to rotate, thereby driving the turntable to rotate. Under the connection of the sliding column, the swing arm swings. Under the meshing of the swing arm and the sliding rod, the sliding rod slides back and forth, thereby driving multiple sets of brushes to remove dust from the dust filter on the back of the ventilation holes. The suction force of the cooling fan during operation automatically removes dust, thereby ensuring the ventilation effect of the ventilation holes and greatly improving the heat dissipation effect of the chassis shell.

[0019] 2. In this utility model, through the cooperative design of the chassis shell, the detachable plate and the fixing cylinder, the detachable plate is slidably installed on the right side of the chassis shell through the connecting edge. When the second spring is compressed, it continuously compresses the limiting ring, so that the fixing post is inserted into the fixing hole to fix the detachable plate. When it is necessary to disassemble the detachable plate, the fixing post is pulled upward so that its bottom end moves out of the fixing hole, thereby releasing the fixation of the detachable plate and allowing the detachable plate to be disassembled. This greatly improves the convenience of disassembling and assembling the detachable plate and facilitates the disassembly and assembly of the components inside the chassis shell.

[0029] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Example:

[0031] See also Figures 1-8 , the utility model provides a technical solution:

[0032] A high-efficiency heat dissipation computer case includes a case shell 1, with multiple sets of ventilation holes 2 on the front of the case shell 1, cooling fans 3 fixedly installed at both the top and bottom ends of the back of the case shell 1, a kick plate 4 fixedly installed at the bottom of the front of the case shell 1, and a removable plate 5 slidably connected to the right side of the case shell 1. The front and rear ends of the top of the removable plate 5 are fixedly connected to the case shell 1 through fixing cylinders 6. The case also includes:

[0033] Dust removal component 7 is fixedly installed at the front end of the top of the chassis shell 1. Dust removal component 7 is used to remove dust from the back of the ventilation hole 2.

[0034] First, a transparent glass plate 101 is fixedly installed on the left side of the chassis shell 1. Support pads 102 are fixedly connected to the four corners of the bottom of the chassis shell 1. When the chassis shell 1 is in use, the transparent glass plate 101 on the outside can be used to enhance the aesthetics and allow observation of the internal condition of the chassis shell 1. The bottom of the chassis shell 1 is supported by multiple sets of support pads 102, which not only allows airflow for heat dissipation but also prevents contact with the ground for moisture protection.

[0035] Furthermore, a dust collection box 103 is slidably connected to the front of the chassis shell 1 and below the multiple ventilation holes 2. The front of the dust collection box 103 has a pull-out groove 104. A dust filter is fixedly installed inside the chassis shell 1 and inside the multiple ventilation holes 2. When the chassis shell 1 is in use, the cooling fan 3 is turned on to draw in external air through the ventilation holes 2 by exhausting air outward. The dust filter prevents dust in the air from entering the interior of the chassis shell 1. Then, the cooling fan 3 exhausts the heat inside the chassis shell 1. With prolonged use, dust will accumulate on the dust filter, causing blockage of the ventilation holes 2. The dust removal component 7 automatically cleans the dust on the dust filter, thereby preventing blockage of the ventilation holes 2. The cleaned dust falls into the dust collection box 103 and is collected. It can be pulled out through the pull-out groove 104 to clean the dust inside the dust collection box 103 at any time.

[0036] Then, connecting posts 401 are fixedly connected to the four corners of the front of the chassis shell 1 and inside the kick plate 4. Sliding sleeves 402 are slidably connected to the outer sides of multiple sets of connecting posts 401. A connecting rod 403 is installed between the sliding sleeve 402 and the kick plate 4, and the two ends of the connecting rod 403 are rotatably connected to the sliding sleeve 402 and the kick plate 4 respectively. A first spring 404 is sleeved on the outer side of the connecting post 401 and on the side of the sliding sleeve 402 away from the connecting rod 403. Since computer cases are often placed under the table near the feet for easy power-on, users may kick the internal components of the chassis shell 1 and cause damage. At this time, the kick plate 4 is used for protection. When the kick plate 4 is subjected to force, it pushes the sliding sleeve 402 to slide on the outer side of the connecting post 401 through the connecting rod 403, so that the sliding sleeve 402 squeezes the first spring 404 to buffer the force, thereby protecting the chassis shell 1 and the internal large components.

[0037] Furthermore, the upper and lower ends of the inner side of the detachable plate 5 are slidably connected to the chassis shell 1 through the connecting edge 501. Multiple sets of protrusions 502 are fixedly connected to the front end of the outer side of the detachable plate 5. The detachable plate 5 is slidably installed on the right side of the chassis shell 1 through the connecting edge 501 and fixed by the fixing cylinder 6. When it is necessary to disassemble or assemble the components inside the chassis shell 1, the fixing cylinder 6 is used to release the fixing of the connecting edge 501, and the detachable plate 5 can be slid and disassembled through the multiple sets of protrusions 502.

[0038] The fixed cylinder 6 has a fixed post 601 slidably connected inside. A limit ring 602 is fixedly connected inside the fixed cylinder 6 and outside the fixed post 601. A second spring 603 is sleeved on the outside of the fixed post 601 and on the top of the limit ring 602. A fixing hole 604 adapted to the fixed post 601 is opened inside the connecting edge 501. When the second spring 603 is pressed, the limit ring 602 is continuously pressed, so that the fixed post 601 is inserted into the fixing hole 604 to fix the detachable plate 5. When the detachable plate 5 needs to be disassembled, the fixed post 601 is pulled upward so that its bottom end moves out of the fixing hole 604, thereby releasing the fixation of the detachable plate 5 and allowing the detachable plate 5 to be disassembled. This greatly improves the ease of disassembly and assembly of the detachable plate 5 and facilitates the disassembly and assembly of the components inside the chassis shell 1.

[0039] Furthermore, the dust removal assembly 7 includes a drive box 701 fixedly installed at the top front of the casing 1. An air duct 702 is fixedly installed on the back of the drive box 701. A rotating shaft 703 is rotatably connected to the top of the drive box 701. A turntable 704 is fixedly connected to the front end of the rotating shaft 703 and inside the drive box 701. An impeller 705 is fixedly connected to the rear end of the rotating shaft 703 and inside the air duct 702. A swing arm 706 is rotatably connected to the drive box 701 below the turntable 704. The front of the turntable 704 is slidably connected to the swing arm 706 via a sliding column 707. A sliding rod 708 is slidably connected to the bottom of the drive box 701. The bottom end of the swing arm 706 engages with the outer side of the slide rod 708. The outer side of the slide rod 708, located on the back of the multiple ventilation holes 2, is fixedly connected to multiple brush plates 709. When the cooling fan 3 is working, some air will enter from the air duct 702 under the action of suction. When the air enters the interior of the air duct 702, it drives the rotating shaft 703 to rotate through the impeller 705, thereby driving the turntable 704 to rotate. Under the connection of the slide column 707, the swing arm 706 swings. Under the engagement of the swing arm 706 and the slide rod 708, the slide rod 708 is driven to slide back and forth, thereby driving the multiple brush plates 709 to remove dust from the dustproof net on the back of the ventilation holes 2.

[0040] Secondly, an air guide cover 710 is fixedly installed on the top of the air guide duct 702. A filter frame 711 is slidably connected to the front of the air guide cover 710. A filter screen is fixedly installed on the inner side of the filter frame 711. External air enters the interior of the air guide duct 702 through the air guide cover 710 and is filtered by the filter screen inside the filter frame 711. When it is necessary to clean the filter screen inside the filter frame 711, simply pull out the filter frame 711 for cleaning.

[0041] Finally, the top of the swing arm 706 is slidably connected to the slide column 707 via the guide groove 712, and both ends of the slide rod 708 are slidably connected to the drive box 701 via the connecting seat 713. Multiple sets of flexible bristles are fixedly connected to the front of the brush plate 709. With the sliding cooperation between the guide groove 712 and the slide column 707 on the inner side of the swing arm 706, the swing arm 706 swings left and right when the turntable 704 rotates. With the meshing of the swing arm 706 and the slide rod 708, the slide rod 708 slides back and forth. When the brush plate 709 moves left and right, the multiple sets of flexible bristles on the front remove dust from the dustproof mesh on the back of the ventilation hole 2. The suction force of the cooling fan 3 automatically removes dust, thereby ensuring the ventilation effect of the ventilation hole 2 and greatly improving the heat dissipation effect of the chassis shell 1.

[0042] In this embodiment, the specific implementation scenario is as follows: When the chassis shell 1 is in use, the cooling fan 3 is activated to draw in external air through the ventilation hole 2 by exhausting air outwards. The dust filter prevents dust in the air from entering the interior of the chassis shell 1. Subsequently, the cooling fan 3 exhausts the heat inside the chassis shell 1. When the cooling fan 3 is working, some air will enter through the air duct 702 under the suction force. When the air enters the interior of the air duct 702, the impeller 705 drives the rotating shaft 703 to rotate, thereby driving the turntable 704 to rotate. Under the connection of the sliding column 707, the swing arm 706 swings. Under the meshing of the swing arm 706 and the sliding rod 708, the sliding rod 708 is driven to slide back and forth, thereby driving the multiple sets of brush plates 709 to ventilate. The dust filter on the back of hole 2 is used for dust removal. The suction force of the cooling fan 3 during operation automatically removes dust, thus ensuring the ventilation effect of ventilation hole 2 and greatly improving the heat dissipation effect of the chassis shell 1. When the second spring 603 is pressed, it continuously presses the limiting ring 602, causing the fixing post 601 to be inserted into the fixing hole 604 to fix the detachable plate 5. When the detachable plate 5 needs to be removed, the fixing post 601 is pulled upward to move its bottom end out of the fixing hole 604, thereby releasing the fixation of the detachable plate 5 and allowing the detachable plate 5 to be removed. The whole operation process is simple and convenient. Compared with the existing computer host case, this utility model can improve the overall heat dissipation effect and ease of disassembly and assembly of the high-efficiency heat dissipation computer host case through design.
