Description

Technical Field

[0001] This utility model relates to the field of computer cases, specifically to a computer case with a three-sided inclined fan bracket. Background Technology

[0002] As the core component of a computer system, the computer chassis is widely used in personal computing, industrial control, data centers, and other fields, and is an important part of the computer hardware technology field. Its technological development has always revolved around three directions: structural optimization, improved heat dissipation efficiency, and enhanced hardware compatibility. Especially with the widespread adoption of high-performance computing devices, the chassis's heat dissipation capacity has become a key factor affecting the overall performance stability of the system.

[0003] Existing computer cases typically employ a cubic frame structure, consisting of a front panel, rear panel, side panels, top panel, and bottom panel forming a closed cavity. During use, users need to install heat-generating components such as the motherboard, CPU, graphics card, and power supply inside the case, and construct a forced convection cooling system using internal or external cooling fans. In a typical structure, the front panel has an air intake and is equipped with a direct-blowing fan array, while the rear panel has a pre-installed single-fan exhaust vent, forming a linear airflow path of "front intake and rear exhaust." The side panels are usually perforated metal plates or house auxiliary cooling fans, the top panel has ventilation holes or sound-dampening material depending on the cooling requirements, and the bottom panel often has a dedicated air intake for power supply cooling.

[0004] However, existing computer chassis ventilation and heat dissipation designs still have significant shortcomings. Specifically, current chassis typically use a front-facing direct-blowing fan to create the airflow, with only a single exhaust fan mounted on the rear panel. This results in inefficient hot air expulsion from the chassis, affecting overall cooling efficiency and potentially causing uneven hardware heat load, directly impacting system stability and lifespan. Furthermore, the single rear exhaust vent design limits airflow scalability and cannot meet the cooling needs of high-power hardware. Therefore, a new computer chassis cooling structure with an efficient airflow system is urgently needed to achieve three-dimensional heat dissipation and efficient thermal management. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies by providing a computer case with a three-sided inclined fan bracket, thereby solving the technical problem of how to optimize the airflow and heat dissipation structure of the computer case to improve its heat dissipation efficiency and performance.

[0006] The objective of this utility model is achieved through the following means:

[0007] A computer case with a three-sided inclined fan bracket includes a case body with an internal cavity. A first and second inclined bracket, both vertically positioned, are connected within the cavity. These brackets are diagonally installed within the cavity, and their inclined spacing creates an air inlet and an air outlet at opposite corners that communicate with the cavity. A first air inlet is obliquely connected to the air inlet on the side of the case near the air inlet, and a first air outlet is connected to the air outlet on the back of the case. This creates an air duct between the first air inlet, the cavity, and the first air outlet. A third inclined bracket is mounted on the bottom wall of the cavity and installed within the cavity via an adjustable bracket. The adjustable bracket has an arc-shaped adjustment groove, allowing the third inclined bracket to be tilted relative to the bottom wall of the cavity via a locking mechanism. Each of the first, second, and third inclined brackets has a mounting position for a fan.

[0008] Furthermore, the cavity is provided with a first support frame and a second support frame for pairing the first inclined bracket and the second inclined bracket, respectively. The first support frame and the second support frame are inserted into the first inclined bracket and the second inclined bracket respectively through a snap-fit ​​structure.

[0009] By setting the first support frame and the second support frame to be inserted into the first and second inclined brackets using a snap-fit ​​structure, the installation and disassembly are simpler and faster. This facilitates maintenance and replacement of the inclined brackets with cooling fans, while ensuring connection stability and thus improving the overall stability of the chassis's heat dissipation structure and improving heat dissipation efficiency.

[0010] Furthermore, as described above, the buckle structure includes a positioning buckle and a positioning post. The sides of both the first support frame and the second support frame are formed with positioning buckles and positioning posts. The first inclined bracket and the second inclined bracket are both provided with insertion slots and positioning holes for matching positioning buckles and positioning posts.

[0011] The matching design of the positioning buckle and positioning post with the insertion slot and positioning hole enables precise docking and installation of the first and second inclined brackets. After the cooling fan is connected to the first and second inclined brackets, it can be quickly matched and installed with the support frame through the buckle structure. This avoids possible offset or misalignment during installation, making the fan bracket installation more precise and ensuring the accuracy of the fan bracket's position after installation. This is conducive to forming a stable and effective heat dissipation airflow and improving heat dissipation efficiency.

[0012] Furthermore, as described above, the first and second inclined brackets are provided with ventilation holes.

[0013] The first and second inclined mounting brackets have ventilation holes, which allow air to flow more smoothly inside the chassis, reduce airflow obstruction, and help air pass through the fan bracket area more quickly, thereby enhancing air circulation and improving the efficiency of hot air exhaust from inside the chassis and improving heat dissipation.

[0014] Furthermore, as described above, there are two adjusting brackets, which are symmetrically installed on the bottom wall of the receiving cavity. A third inclined bracket is installed between the two adjusting brackets. The adjusting brackets have raised adjusting parts, and arc-shaped adjusting grooves extend along the adjusting parts, so that the locking member passes through the arc-shaped adjusting grooves and connects with the adjusting brackets.

[0015] The design of two symmetrically installed adjustment brackets and an arc-shaped adjustment groove allows the third angled bracket to be adjusted along the arc-shaped adjustment groove using locking components. This enables flexible adjustment of the fan installation angle on the third angled bracket according to the layout and cooling requirements of the internal hardware, optimizing the airflow direction and ensuring the airflow better meets the hardware's cooling needs. This improves the targetedness and effectiveness of cooling, satisfying the cooling requirements of different hardware configurations.

[0016] Furthermore, as described above, both the first air inlet and the first air outlet are connected to dustproof mesh.

[0017] Dust filters are connected to the first air inlet and the first air outlet to effectively prevent external dust from entering the chassis. The dust filters reduce dust intrusion, keep the inside of the chassis clean, and contribute to the long-term stable operation of the hardware.

[0018] Furthermore, as described above, the bottom of the housing is provided with a second air inlet communicating with the receiving cavity, and the top of the housing is provided with a second air outlet communicating with the receiving cavity. The second air inlet and the second air outlet are arranged opposite to each other.

[0019] A second air inlet is located at the bottom of the chassis, and a second air outlet is located at the top, with the two outlets positioned opposite each other to form a vertical ventilation channel. This increases the airflow path and volume within the chassis, and works in conjunction with the existing airflow channel formed by the three-sided angled fan brackets to further enhance air circulation inside the chassis, allowing hot air to be exhausted from multiple directions and improving the overall heat dissipation efficiency of the chassis.

[0020] Furthermore, as described above, the side of the housing is connected to a transparent side panel that provides a visible accommodating cavity.

[0021] The side panel of the chassis is connected to a transparent side panel that allows users to observe the operating status of the internal hardware and the operation of the fans without opening the chassis, and also improves the aesthetics of the chassis.

[0022] Furthermore, as described above, the first and second inclined brackets are respectively connected to the sides of a first set of cooling fans and a second set of cooling fans, the third inclined bracket is connected to a third set of cooling fans, and the top wall of the receiving cavity is connected to a fourth set of cooling fans via a mounting bracket.

[0023] Multiple cooling fans are installed on the first, second, and third inclined mounting brackets, as well as on the top wall of the housing cavity, forming a three-dimensional airflow layout for heat dissipation. The coordinated operation of these multiple fans allows for cooling of the chassis interior from different directions, significantly increasing airflow and heat dissipation area. This ensures that heat is removed from all areas of the chassis more quickly, improving the overall cooling efficiency and performance of the computer chassis.

[0024] The beneficial effects of this utility model are as follows: By connecting a first and a second vertically mounted oblique bracket installed diagonally within the housing cavity, an air inlet and an air outlet communicating with the housing cavity are formed diagonally within the housing. Simultaneously, a first air inlet is opened on the side of the housing near the air inlet, and a first air outlet is provided on the back, forming a ventilation channel connecting the first air inlet, the housing cavity, and the first air outlet. This diagonal air inlet and outlet arrangement more effectively exhausts hot air from inside the housing, significantly improving the heat dissipation efficiency of the computer housing. Furthermore, a third oblique bracket is installed on the bottom wall of the housing cavity via an adjustable bracket. The three-angle mounting bracket can be tilted relative to the bottom wall of the housing via the locking mechanism along the arc-shaped adjustment groove. This allows the third angle mounting bracket to be flexibly adjusted according to needs, improving the adaptability and flexibility of fan installation and further optimizing the heat dissipation effect. By setting up the first, second, and third angle mounting brackets, the number of fans can be increased to the maximum extent at the installation position, enhancing heat dissipation performance and more comprehensively removing the heat generated by the hardware in the housing. This optimizes the airflow structure of the computer case and improves the heat dissipation efficiency and performance of the computer case. Attached Figure Description

They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] In this embodiment, refer to Figures 1-8The present invention relates to a computer case with a three-sided inclined fan bracket, comprising a case body 1, the interior of which forms a receiving cavity 2. A first inclined bracket 3 and a second inclined bracket 4, both vertically arranged, are connected to the receiving cavity 2. The first inclined bracket 3 and the second inclined bracket 4 are diagonally installed within the receiving cavity 2 of the case body 1. The inclined spacing of the first inclined bracket 3 and the second inclined bracket 4 creates an air inlet chamber 5 and an air outlet chamber 6, respectively, communicating with the receiving cavity 2, at opposite corners of the case body 1. A first air inlet 7, obliquely connected to the air inlet chamber 5, is provided on the side of the case body 1 near the air inlet chamber 5. The back of the housing 1 is provided with a first air outlet 8 that communicates with the air outlet chamber 6, so that the first air inlet 7 and the receiving cavity 2 and the first air outlet 8 form an air duct. A third inclined bracket 9 is provided on the bottom wall of the receiving cavity 2. The third inclined bracket 9 is installed in the receiving cavity 2 through an adjusting bracket 10. An arc-shaped adjusting groove 11 is provided on the adjusting bracket 10, so that the third inclined bracket 9 can be tilted relative to the bottom wall of the receiving cavity 2 by means of a locking member 12. The first inclined bracket 3, the second inclined bracket 4 and the upper third inclined bracket 9 are all provided with mounting positions 13 for installing fans.

[0038] The first, second, and third inclined mounting brackets are all equipped with mounting positions for installing fans. The reasonable arrangement of the mounting positions facilitates fan installation and also makes it easier to maintain and replace the fans later, reducing usage costs and maintenance difficulty.

[0039] The cavity 2 is provided with a first support frame 14 and a second support frame 15 for pairing the first inclined bracket 3 and the second inclined bracket 4 respectively. The first support frame 14 and the second support frame 15 are inserted into the first inclined bracket 3 and the second inclined bracket 4 respectively through a snap-fit ​​structure.

[0040] By setting the first support frame 14 and the second support frame 15 to be inserted into the first inclined bracket 3 and the second inclined bracket 4 using a snap-fit ​​structure, the installation and disassembly are simpler and faster. This facilitates maintenance and replacement of the inclined bracket with the cooling fan, while ensuring the stability of the connection and thus improving the stability of the entire chassis cooling structure and improving the cooling efficiency.

[0041] The buckle structure includes a positioning buckle 16 and a positioning post 17. The first support frame 14 and the second support frame 15 both have positioning buckles 16 and positioning posts 17 on their sides. The first inclined bracket 3 and the second inclined bracket 4 both have insertion slots 18 and positioning holes 19 for matching positioning buckles 16 and positioning posts 17.

[0042] The matching design of the positioning buckle 16 and positioning post 17 with the insertion slot 18 and positioning hole 19 can accurately connect and install the first inclined bracket 3 and the second inclined bracket 4. After the cooling fan is connected to the first and second inclined brackets 4, it can be quickly matched and installed with the support frame through the buckle structure. This avoids possible offset or misalignment during installation, making the fan bracket installation more precise and ensuring the accuracy of the fan bracket position after installation. This is conducive to forming a stable and effective heat dissipation airflow and improving heat dissipation efficiency.

[0043] The first inclined bracket 3, the second inclined bracket 4, and the third inclined bracket 9 are all provided with ventilation holes 20.

[0044] The first inclined mounting bracket 3 and the second inclined mounting bracket 4 have ventilation holes 20, which allow air to flow more smoothly inside the chassis, reduce the obstruction of air flow, help air pass through the fan bracket area more quickly, enhance air circulation, thereby improving the efficiency of hot air exhaust inside the chassis and improving the heat dissipation effect.

[0045] Two adjustment brackets 10 are provided, and the two adjustment brackets 10 are symmetrically installed on the bottom wall of the receiving cavity 2. The third oblique bracket 9 is installed between the two adjustment brackets 10. A protruding adjustment part 21 is formed on the adjustment bracket 10. The arc-shaped adjustment groove 11 extends along the adjustment part 21, so that the locking member 12 passes through the arc-shaped adjustment groove 11 and connects with the adjustment bracket 10.

[0046] The design of two symmetrically installed adjustment brackets 10 and an arc-shaped adjustment groove 11 allows the third angled bracket 9 to be tilted along the arc-shaped adjustment groove 11 via the locking element 12. This allows for flexible adjustment of the fan installation angle on the third angled bracket 9 according to the layout and heat dissipation requirements of the internal hardware, optimizing the airflow direction and ensuring the airflow better meets the hardware's heat dissipation needs, improving the targetedness and effectiveness of heat dissipation, and satisfying the heat dissipation requirements of different hardware configurations.

[0047] Both the first air inlet 7 and the first air outlet 8 are equipped with dust filters. These dust filters effectively prevent external dust from entering the chassis. The dust filters reduce dust intrusion, maintain the cleanliness of the chassis interior, and contribute to the long-term stable operation of the hardware.

[0048] The bottom of the housing 1 is provided with a second air inlet 22 that communicates with the receiving cavity 2, and the top of the housing 1 is provided with a second air outlet 23 that communicates with the receiving cavity 2. The second air inlet 22 and the second air outlet 23 are arranged opposite to each other.

[0049] A second air inlet 22 is located at the bottom of the chassis 1, and a second air outlet 23 is located at the top, with the two positioned opposite each other to form a vertical ventilation channel. This increases the airflow path and volume within the chassis, and works in conjunction with the existing airflow channel formed by the three-sided angled fan brackets to further enhance air circulation inside the chassis, allowing hot air to be exhausted from multiple directions and improving the overall heat dissipation efficiency of the chassis.

[0050] The side of the enclosure 1 is connected to a transparent side panel 24 that allows for viewing of the cavity 2. This allows users to observe the internal hardware's operating status and fan operation without opening the enclosure, and also improves the enclosure's aesthetics.

[0051] The first inclined bracket 3 and the second inclined bracket 4 are respectively connected to the first set of cooling fans (not shown) and the second set of cooling fans (not shown). The third inclined bracket 9 is connected to the third set of cooling fans (not shown). The top wall of the receiving cavity 2 is connected to the fourth set of cooling fans (not shown) through the mounting bracket 25.

[0052] Multiple cooling fans are installed on the first inclined bracket 3, the second inclined bracket 4, the third inclined bracket 9, and the top wall of the receiving cavity 2, forming a three-dimensional airflow layout for heat dissipation. The coordinated operation of these multiple fans allows for heat dissipation from different directions inside the chassis, significantly increasing airflow and heat dissipation area. This ensures that heat is removed from all areas inside the chassis more quickly, improving the overall heat dissipation efficiency and performance of the computer chassis.

[0053] In some embodiments, the first inclined bracket 3, the second inclined bracket 4 and the third inclined bracket 9 are all provided with mounting positions 13 for installing fans on the mounting bracket 25. The number and position of the cooling fans are matched with the mounting positions 13. For example, the number of cooling fans can be set according to actual needs. For example, two cooling fans are set for each group, so that there are four groups of cooling fans, and eight cooling fans are provided inside the housing 1.

[0054] Specifically, in this embodiment, the first inclined bracket 3, the second inclined bracket 4, and the third inclined bracket 9 are each provided with three mounting positions 13 on the mounting bracket 25, so that four sets of cooling fans can be installed in the housing 1 to the maximum extent, and each set of cooling fans includes three, thereby improving the heat dissipation effect on the internal hardware of the housing 1 by setting twelve cooling fans. Specifically, the twelve cooling fans are arranged in a front three, rear three, bottom three, and top three configuration.

[0055] The installation and setup of cooling fans are standard techniques for those skilled in the art and will not be described in detail here. For example, cooling fans may be PHANTEKS M25-120 / M25-140, Geometry Future Dragon Scale 2503R-14CM, or ASUS ROG STRIX Wind God XF120, etc.

[0056] The specific operating principle in this embodiment is as follows:

[0057] The first support frame 14 and the second support frame 15 are installed diagonally in the receiving cavity 2. The first set of cooling fans and the second set of cooling fans are connected to the first set of inclined brackets 3 and the second set of inclined brackets 4 respectively, so that the first set of inclined brackets 3 and the second set of inclined brackets 4 are connected to the first support frame 14 and the second support frame 15 respectively through a snap-fit ​​structure. The third set of cooling fans is paired and installed on the third set of inclined brackets 9, so that the third set of inclined brackets 9 is connected to the arc-shaped adjustment groove 11 through the locking member 12. Specifically, the locking member 12 is composed of locking bolts, so that the locking bolts pass through the arc-shaped adjustment groove 11 and are connected to the third set of inclined brackets 9. The fourth set of cooling fans is installed on the top of the receiving cavity 2 through the mounting bracket 25. The first and second air inlets 22 opened in the box 1 can introduce external cold air into the receiving cavity 2, and the first and second air outlets 23 can exhaust the hot air in the receiving cavity 2, thereby further improving the heat dissipation efficiency of the internal hardware of the box 1.

[0058] By connecting the first and second diagonally mounted vertical brackets 3 and 4 diagonally within the cavity 2 of the enclosure 1, air inlet chambers 5 and 6, respectively, are formed diagonally within the enclosure 1, communicating with the cavity 2. Simultaneously, a first air inlet 7 is opened on the side of the enclosure 1 near the air inlet chamber 5, and a first air outlet 8 is provided on the back. This forms a continuous ventilation channel between the first air inlet 7, the cavity 2, and the first air outlet 8. The diagonal air inlet and outlet effectively expel hot air from inside the enclosure, significantly improving the cooling efficiency of the computer enclosure. Furthermore, by adjusting the bracket 10 to install a third diagonal bracket 9, the tilt angle of which can be flexibly adjusted as needed, further optimizing the cooling effect. Through the arrangement of the first, second, and third diagonal brackets 3, and 4, and by maximizing the number of fans at the mounting position 13, three-dimensional cooling is achieved, enhancing heat dissipation performance. This allows for more comprehensive removal of heat generated by the hardware within the cavity 2, thereby optimizing the airflow structure of the computer enclosure and improving its cooling efficiency and performance.
