Description

Technical Field

[0001] The present application belongs to the technical field of computer-aided equipment, and in particular, relates to a heat dissipation fan and a fan combination with a display function. Background Art

[0002] The main chassis of a computer is generally provided with cooling fans, which are used to dissipate heat from the internal environment of the chassis and the electrical components in the chassis. For components with high heat generation, such as the central processing unit (CPU) and the graphics card, it is necessary to set a cooling fan on them to achieve the purpose of cooling and heat dissipation. In practical applications, the heating temperature of the above components needs to be monitored in real time, such as the temperature of the CPU or graphics card during operation, or the operating speed, temperature, and operating time of the cooling fan. Users or testers prefer to be able to observe the operating data intuitively, so as to monitor the operating status in real time. Since the above-mentioned heating components are purchased parts, it is impossible to directly install a display screen on them. The currently feasible solution is to set a display screen on the cooling fan, and connect the display screen to the motherboard through a line to obtain and display the operating data.

[0003] As users are becoming more and more fond of DIY computer mainframes, they buy a transparent mainframe case to observe the operation status of various electrical components inside the mainframe case, and add lighting, water cooling systems, etc. to make the computer mainframe more colorful, bright, and extraordinarily showy and beautiful. The cooling fan with a display screen in the prior art has a single function and can only display operating data, and cannot be used as a lighting to add luster to the above-mentioned mainframe case. In addition, the visible area of the display screen on the cooling fan is small. If a display screen with a large display area is used, the size of the original cooling fan will be changed, resulting in an increase in the size of the cooling fan and a high cost of modification; and because the specifications of the cooling fan have changed, the problem of installation adaptability has further arisen.

[0004] It can be seen that the display screens built into the cooling fans currently used in computers no longer meet the needs of today's computer DIY users. Summary of the invention

[0005] The purpose of the embodiments of the present application is to provide a heat dissipation fan and a fan combination to solve the technical problem that the display screen attached to the heat dissipation fan in the prior art has a single function and a small visible area.

The bottom plate is provided with a through hole corresponding to the position of the electrical contact on the fan body, and the electrical contact extends from the through hole. The display screen in the display module is accommodated between the cover body and the bottom plate to avoid direct contact with foreign objects, thereby improving the protection effect of the display screen.

[0013] In one embodiment, a mounting grid for mounting the second magnetic member is provided on the inner wall of the cover body, and the second magnetic member is disposed on the mounting grid and extends toward the bottom plate. The extension end of the second magnetic member may be close to the bottom plate or abut against the bottom plate to fine-tune the magnetic attraction strength between the first magnetic member and the second magnetic member.

[0014] In one embodiment, a buckle ring for mounting and connecting with the cover body is provided on the edge of the bottom plate, and a buckle block for buckling with the buckle ring is provided on the cover body. The buckle ring and the buckle block are buckled together to tightly fix the cover body on the bottom plate, effectively ensuring the connection stability and sealing.

[0015] In one embodiment, connecting lugs are provided at at least one end of the display screen. Connecting holes are provided on the connecting lugs, screw holes are provided on the bottom plate, and mounting holes are provided on the cover body.

At least one side wall of the outer shell is the first splicing end, and positioning grids for mounting the first magnetic member are provided on the side wall of the outer shell. The first magnetic member is arranged in the positioning grid so as to magnetically attract with the second magnetic member on the display module.

[0017] In one embodiment, a terminal module for setting the electrical contacts is provided on the fan body. A fixing grid for mounting the terminal module and a through hole communicating with the outside are further provided on the side wall of the outer shell. The electrical contacts on the terminal module are exposed in the through hole so as to contact the electrical contacts on the display module, realizing the electrical connection between the display module and the fan body.

[0018] The present application also provides a fan combination, including the heat dissipation fan described above. The fan combination is formed by splicing a plurality of the heat dissipation fans adjacent to each other. The first splicing ends on the plurality of heat dissipation fans are all located on the same side of the fan combination. The display modules are respectively mounted on each of the heat dissipation fans so that the side part of the entire fan combination can have a lighting effect composed of a plurality of display modules.

At least one of the plurality of heat dissipation fans is the heat dissipation fan of the present application. The display module is mounted on the fan body, and the display module extends to other heat dissipation fans so that a complete large screen is formed on the side part of the entire fan combination, thereby improving the display effect.

[0020] The beneficial effects of the heat dissipation fan and the fan combination provided by the present application are as follows: Compared with the prior art, the heat dissipation fan of the present application includes a fan body and a display module. The display module can be selectively mounted on the fan body as an independent functional module. Therefore, the volume of the display module, the visible area of the screen on the display module, and the functional components are not limited by the specifications of the fan. A display screen with a larger visible area and richer display functions can be set on the display module so that in addition to displaying operation data, corresponding color patterns can also be displayed on the display module, and the display module can be used as a lighting device on the heat dissipation fan. A plurality of heat dissipation fans of the present application can be spliced adjacent to each other to form a fan combination, thereby constituting a complete lighting pattern, effectively improving the aesthetic sense and gorgeousness of the heat dissipation fan, and being beneficial to meeting the usage requirements of DIY users.

[0021] In addition, since the display module is a separate component, magnetic components that are magnetically attracted to each other are provided on the display module and the fan body, so that the display module can be magnetically fixed on the fan body. Multiple parts for magnetically fixing the display module can be preset on the fan body, so that the display module can be selectively arranged on the corresponding parts of the fan body. On the one hand, it is beneficial to adapt to the installation environment of the cooling fan and improve the installation adaptability of the cooling fan in various application parts inside the computer main case. On the other hand, DIY users can flexibly adjust the installation position of the display module according to DIY needs, so as to obtain a better lighting effect and further improve the aesthetic feeling of the computer main case.

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] Traditional cooling fans with display screens have a single function of the display screen on the cooling fan, which can only display operating data, such as simple values such as speed, temperature and operating time, and cannot add more brilliance to the host chassis, such as patterns. In addition, considering factors such as production costs and available space on the cooling fan, the size of the display screen is restricted. If a larger viewing area or a screen with more functions is required, the larger screen volume will change the specifications of the original cooling fan, and the cooling fan will need a larger volume to accommodate the changed screen size. If the specifications of the cooling fan are changed, further installation adaptability issues will arise. Therefore, traditional cooling fans cannot be replaced with high-performance screens with larger viewing areas and richer display content according to demand.

[0048] Here, the embodiment of the present application provides a new type of cooling fan and fan combination thereof, and the display screen can be used as a separate functional module, allowing users to flexibly install it on a single cooling fan or a fan combination composed of multiple cooling fans. In addition, the appearance and performance of the display screen are not restricted by the specifications of the cooling fan, which effectively improves the performance of the display module applied to the cooling fan and can increase the visible area, solving the technical problem that the display screen on the traditional cooling fan has a single function and a small visible area. It is now described in detail.

[0049] Please also read Figure 1 , Figure 2 and Figure 3 The heat dissipation fan 100 includes a fan body 1 and a display module 2. The display module 2 is a separate component and can be installed on the fan body 1 according to usage requirements.

[0050] like Figure 2As shown, at least one first splicing end 11 for installing the display module 2 is provided on the fan body 1, and electrical contacts 12 are provided on the first splicing end 11. The electrical contacts 12 are connected to the control circuit inside the fan body 1.

[0051] It should be noted that multiple first splicing ends 11 for installing the display module 2 can be provided on the fan body 1. In this embodiment, the fan body 1 is a fan with a quadrilateral housing 13. All four sides of the housing 13 of the fan body 1 can serve as the first splicing ends 11, and the display module 2 can be selectively installed on any side of the fan body 1.

[0052] As Figure 3 shown, a second splicing end 21 is provided on the display module 2. The second splicing end 21 is used to be spliced with the first splicing end 11 on the above-mentioned fan body 1, and electrical contacts 22 corresponding to the positions of the electrical contacts 12 are provided on the second splicing end 21.

[0053] Magnetic attraction components that are magnetically attracted to each other are also provided between the display module 2 and the fan body 1. The magnetic attraction components are respectively arranged on the first splicing end 11 and the second splicing end 21, so that the fan body 1 and the display module 2 can be magnetically connected, and the electrical contacts 12 and the electrical contacts 22 are synchronously contacted to realize the simultaneous connection of electrical signals.

[0054] Compared with the prior art, the cooling fan 100 provided by the embodiment of the present application includes a fan body 1 and a display module 2. The display module 2 can be selectively installed on the fan body 1 as a separate functional module. Therefore, the volume of the display module 2, the visible area of the screen on the display module 2, and functional components are not limited by the specifications of the fan. A display screen with a larger visible area and richer display functions can be set on the display module 2, so that in addition to displaying operation data, corresponding color patterns can also be displayed on the display module 2, and the display module 2 can be used as a lighting fixture on the cooling fan 100. Multiple cooling fans 100 of the present application can be spliced adjacent to each other to form a fan combination, thereby forming a complete lighting pattern, effectively improving the aesthetic feeling and gorgeous feeling of the cooling fan 100, and being beneficial to meeting the usage requirements of computer DIY users.

[0055] In addition, since the display module 2 is a separate component, magnetic components that are magnetically attracted to each other are provided on the display module 2 and the fan body 1, so that the display module 2 can be magnetically fixed on the fan body 1. Multiple positions for magnetically fixing the display module 2 can be preset on the fan body 1, so that the display module 2 can be selectively arranged at corresponding positions on the fan body 1. On the one hand, it is beneficial to adapt to the installation environment of the cooling fan 100 and improve the installation adaptability of the cooling fan 100 at various application positions inside the computer main chassis. On the other hand, DIY users can flexibly adjust the installation position of the display module 2 according to DIY needs, thereby obtaining a better lighting effect and further improving the aesthetic feeling of the computer main chassis.

[0056] On the cooling fan 100 of the present application, a magnetic connection method is adopted between the display module 2 and the fan body 1. Compared with the connection method using snap connection, the operation of magnetic connection is simpler, and since the connection part is not restricted by the snap connection part, fine-tuning operation is convenient, which is beneficial to correcting tolerances or position deviations and effectively improves the installation adaptability.

[0057] For the magnetic structure between the display module 2 and the fan body 1, in an embodiment of the present application, the magnetic component includes a first magnetic member 31 and a second magnetic member 32. Please refer to Figure 2 and Figure 6 , the first magnetic member 31 is arranged on the first splicing end 11 of the fan body 1; please refer to Figure 3 and Figure 5 , the second magnetic member 32 is arranged on the second splicing end 21 of the display module 2.

[0058] For the first magnetic member 31 and the second magnetic member 32, specifically, a magnetic attraction combination of magnet and magnet can be preferably used, or a magnetic attraction combination of magnet and magnetizable metal such as iron can also be preferably used. It can be specifically set according to usage requirements and is not specifically limited here.

[0059] Among them, there are at least two first magnetic members 31, the number of the second magnetic members 32 is the same as that of the first magnetic members 31, and the positions correspond one by one.

[0060] In this embodiment, at least two groups of first magnetic members 31 and second magnetic members 32 that are magnetically attracted to each other can be arranged on the first splicing end 11 and the second splicing end 21.

[0061] In this way, at least two groups of first magnetic members 31 and second magnetic members 32 are magnetically attracted to each other to limit the installation posture of the display module 2 magnetically fixed on the fan body 1, effectively improving the stability of the display module 2 installed on the fan body 1.

[0062] For the structure of the display module 2, in an embodiment of the present application, please refer to Figure 4 andFigure 5 The display module 2 includes a display screen 23, a bottom plate 24, and a cover 25 disposed on the bottom plate 24. The display screen 23 is received between the bottom plate 24 and the cover 25, and the electrical contact 22 is provided on the display screen 23.

[0063] The cover 25 has an opening 251 that is positionally matched with the display portion on the display screen 23. The shape and size of the opening 251 are adapted to the display portion on the display screen 23, so that the content displayed on the display screen 23 is presented through the opening 251.

[0064] In this embodiment, the shape of the display module 2 is matched with the shape of the side portion of the fan main body 1. The display module 2 can preferably be a flat rectangular block. The display portion on the display screen 23 is a long rectangular surface, and the opening 251 on the cover 25 is a rectangular frame, so that the display portion (screen) on the internal display screen 23 can be exposed in the opening 251.

[0065] The outer end face of the bottom plate 24 serves as the second splicing end 21 on the display module 2. A through hole 241 corresponding to the position of the electrical contact 12 on the fan main body 1 is provided on the bottom plate 24. The electrical contact 22 on the display screen 23 extends out from the through hole 241 to contact the electrical contact 12 on the fan main body 1.

[0066] In this way, the display screen 23 in the display module 2 is received between the cover 25 and the bottom plate 24, avoiding direct contact with external objects and improving the protection effect on the display screen 23. The cover 25 has an opening 251 adapted to the display portion on the display screen 23, so as to maximize the visible area of the display screen 23.

[0067] Regarding the installation structure of the second magnetic member 32 on the display module 2, in an embodiment of the present application, please refer to Figure 4 and Figure 5 The inner wall of the cover 25 is provided with an installation grid 252 for setting the second magnetic member 32. The second magnetic member 32 is disposed on the installation grid 252 and extends towards the bottom plate 24.

[0068] In practical applications, the magnetic attraction strength between the first magnetic member 31 and the second magnetic member 32 affects the connection stability between the display module 2 and the fan main body 1. If the magnetic attraction strength is weak, the display module 2 is likely to fall off the fan main body 1; if the magnetic attraction strength is strong, it is not easy to disassemble the display module 2 from the fan main body 1. Therefore, for the magnetic attraction strength between the first magnetic member 31 and the second magnetic member 32, it can be slightly adjusted by the part between the extending end of the second magnetic member 32 and the bottom plate 24.

[0069] In this embodiment, two installation grids 252 are respectively provided on the inner wall of the cover body 25 near the two ends, and each installation grid 252 is provided with a second magnetic member 32, and each second magnetic member 32 extends from the installation grid 252 to the bottom plate 24. The extension end of the second magnetic member 32 can be close to the inner wall of the bottom plate 24, or it can be against the inner wall of the bottom plate 24. Here, adaptive fine adjustment can be made according to the demand for magnetic attraction strength, so as to effectively adjust the magnetic attraction strength between the first magnetic member 31 and the second magnetic member 32.

[0070] For the mounting structure between the bottom plate 24 and the cover 25 on the display module 2, in one embodiment of the present application, please refer to Figure 4 and Figure 5 A buckle ring 242 for mounting and connecting with the cover body 25 is provided on the edge of the bottom plate 24 , and a buckle block 253 for buckling and cooperating with the buckle ring 242 is provided on the cover body 25 .

[0071] In this embodiment, buckle rings 242 are evenly distributed on the edge of the bottom plate 24, and these buckle rings 242 all have buckle holes; correspondingly, the inner wall outer periphery of the cover body 25 has a peripheral edge 254, and the peripheral edge 254 is provided with buckle blocks 253 whose number is the same as the buckle rings 242 and whose positions correspond one to one. The buckle rings 242 and the buckle blocks 253 are buckled together to tightly fix the cover body 25 on the bottom plate 24, effectively ensuring the stability and sealing of the connection, and improving the protection effect of the display screen 23.

[0074] Regarding the structure on the fan body 1, in an embodiment of the present application, please also refer to Figure 6 and Figure 7 , the fan body 1 includes a quadrilateral housing 13. At least one side wall of the housing 13 is a first splicing end 11, and a positioning grid 131 for installing the first magnetic member 31 is provided on the side wall of the housing 13. The first magnetic member 31 is arranged in the positioning grid 131 so as to magnetically attract the second magnetic member 32 on the display module 2.

[0075] In practical applications, the fan body 1 preferably adopts a quadrilateral housing 13, and an impeller, a motor, etc. are arranged in the middle of the housing 13. The available space on the fan body 1 is mainly in the area between the impeller and the housing 13, especially in the area between the impeller and the four corners of the housing 13. Herein, the first magnetic member 31 can be arranged inside the four side walls of the quadrilateral housing 13, especially in the triangular area between the impeller and the corners of the housing 13 on the inner side wall of the housing 13. A larger-sized first magnetic member 31 can be used and arranged on the fan body 1 to ensure the magnetic attraction area and magnetic attraction strength.

[0076] In this embodiment, as shown in Figure 6 and Figure 7 , the housing 13 includes an upper housing 132 and a lower housing 133, and the upper housing 132 and the lower housing 133 are spliced up and down to form a complete housing 13. Positioning grids 131 corresponding in position are respectively provided on the side walls of the upper housing 132 and the lower housing 133. A part of the first magnetic member 31 can be inserted into the positioning grid 131 of the upper housing 132, and another part of the first magnetic member 31 can be arranged on the positioning grid 131 of the lower housing 133. Thus, through the up-and-down splicing of the upper housing 132 and the lower housing 133, the first magnetic member 31 is installed and fixed in the positioning grid 131, which is convenient for disassembly and replacement and improves the installation efficiency of the first magnetic member 31.

Please refer to Figure 9 , the embodiment of the present application also provides a fan combination 200, including the cooling fan 100 provided by the embodiment of the present application. The fan combination 200 is composed of a plurality of cooling fans 100 of the present application spliced adjacent to each other, and the fan combination 200 can be arranged on the heat dissipation water radiator 300 of the water cooling system.

[0080] Among them, the first splicing ends 11 on the plurality of cooling fans 100 are all located on the same side of the entire fan combination 200, and display modules 2 are respectively installed on each cooling fan 100.

[0081] As Figure 9 shown, the width of each display module 2 is similar to the side wall thickness of the fan body 1, so that the side part of the entire fan combination 200 can have a lighting effect composed of a plurality of display modules 2.

[0082] In another embodiment of the present application, as Figure 10 shown, the width of each display module 2 can be greater than the side wall thickness of the fan body 1, so that each display module 2 can extend to the side part of the heat dissipation water radiator 300 to be used for covering the heat dissipation water radiator 300, thereby increasing the visible area.

[0083] In another embodiment of the present application, please refer to Figure 11 , the embodiment of the present application also provides another fan combination 200, which is composed of a plurality of cooling fans 100 spliced adjacent to each other. At least one of the plurality of cooling fans 100 is the cooling fan 100 provided by the embodiment of the present application. A display module 2 is installed on the fan body 1 and extends to other cooling fans 100, so that a complete large screen is formed on the side part of the entire fan combination 200, effectively improving the display effect.

[0084] In this embodiment, as Figure 11 shown, the fan combination 200 is formed by splicing three cooling fans 100 adjacent to each other. The display module 2 can preferably be a strip-shaped display screen whose length matches the sum of the side wall lengths of the three cooling fans 100. One of the three cooling fans 100 on the side is the cooling fan 100 of the present application. The display module 2 is magnetically connected and electrically connected to the cooling fan 100 of the present application and extends to the other two ordinary cooling fans 100 to cover the same side surface of each cooling fan 100.

[0085] In other embodiments (not shown in the figures), it is also possible that the middle one of the three heat dissipation fans 100 adopts the heat dissipation fan 100 of the present application. The display module 2 is magnetically and electrically connected to the heat dissipation fan 100 of the present application. Both ends of the display module 2 extend towards the ordinary heat dissipation fans 100 on both sides, and can also cover the same side of each heat dissipation fan 100.

[0086] In another embodiment of the present application, as Figure 12 shown, the width of the display module 2 can be greater than the side wall thickness of each heat dissipation fan 100, so that the display module 2 can extend to the side of the heat dissipation water tank 300 to be used for shielding the heat dissipation water tank 300 and further increasing the visible area.

[0087] In practical applications, since a relatively large-sized display module 2 is adopted and the weight of the display module 2 is heavy, it is insufficient in stability to magnetically fix it only with the magnetic attraction components on one heat dissipation fan 100. Therefore, in order to ensure the installation stability of the display module 2, in another embodiment of the present application (not shown in the figures), in the above-mentioned fan combination 200, it is preferable to additionally install the magnetic attraction components of the present application on the side walls of other ordinary heat dissipation fans 100, and use the magnetic attraction components to magnetically fix the extended part of the display module 2, effectively improving the fixing effect on the display module 2.

[0088] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
