Description

Technical Field

[0001] This invention relates to the field of computer heat dissipation design technology, specifically to a computer heat dissipation structure and a computer structure. Background Technology

[0002] A graphics card (Video Card / Graphics Card) is a core hardware component in a computer responsible for processing and displaying graphics data. Its core functions include graphics signal conversion, graphics rendering and acceleration, and parallel computing acceleration, among others.

[0003] In the existing related technologies, the following shortcomings still exist in the use of graphics cards: First, the heat generated by a graphics card during operation is generally dissipated by a cooling fan. However, existing cooling fans can generally only dissipate heat from the top of the graphics card (i.e., the fan side), while the bottom (the fanless side) cannot effectively guarantee heat dissipation.

[0004] Secondly, when the computer is not in use, dust can enter the case through the ventilation holes and accumulate on the surface of the graphics card or the graphics card fan, affecting its heat dissipation effect and heat dissipation capacity. Summary of the Invention

[0005] In order to solve the technical problems in related technologies, the present invention provides a computer heat dissipation structure and a computer structure.

[0006] To achieve the above objectives, the present invention provides a computer heat dissipation structure for graphics card heat dissipation, comprising: The combined board is formed into a U-shaped structure. The combined board includes a first board and a second board disposed opposite to each other, and a third board connected between the first board and the second board. The U-shaped structure is used to accommodate a graphics card. The sides of the first board, the second board and the third board near the graphics card are respectively recessed inward to form a first cavity, a second cavity and a third cavity that are interconnected. The second cavity is connected to the outside. A sealing plate, which is connected to the combined plate and is used to abut against the end of the graphics card that is furthest from the display interface; The first plate is used to cover the fan surface of the graphics card. The first plate has several inclined ventilation holes on the side near the graphics card. The ventilation holes include a first end and a second end that are arranged opposite to each other. The first end is connected to the first cavity and the first cavity is connected to the outside through the ventilation holes. The first end is closer to the third plate than the second end.

[0007] Optionally, the end of the first plate away from the third plate is configured to be flush with the end face of the graphics card.

[0008] Optionally, the second board is configured such that the distance between the end of the second board away from the third board and the end of the graphics card having a bus interface is less than or equal to 2 cm.

[0009] Optionally, the radial dimension of the ventilation hole gradually decreases in the direction from the second end to the first end.

[0010] Optionally, the computer heat dissipation structure further includes a dust reduction component, which includes several cylindrical mesh structures. The shape of the cylindrical mesh structures is adapted to the ventilation holes, and the several cylindrical mesh structures are respectively used to be installed in the several ventilation holes.

[0011] Optionally, the dust reduction assembly further includes two mounting posts and several connectors. The two ends of each pair of adjacent cylindrical mesh structures are respectively connected to the two connectors. The two mounting posts are disposed on the first plate and / or the sealing plate. The mounting posts are used for detachable connection with the connectors.

[0012] Optionally, the computer heat dissipation structure further includes a dust-blocking component disposed within the second cavity. The dust-blocking component includes a first dust-blocking plate and a second dust-blocking plate spaced apart. The two ends of the first dust-blocking plate and the second dust-blocking plate are respectively connected to the second plate and the sealing plate. The first dust-blocking plate and the second dust-blocking plate are arranged perpendicular to each other, and in the direction from the third plate to the graphics card, the projection of the first dust-blocking plate and the projection of the second dust-blocking plate are in contact with each other.

[0013] Optionally, the shortest distance between the first dust barrier and the second dust barrier is greater than or equal to 0.8 cm.

[0014] According to a second aspect of the present invention, a computer structure is also provided, including a graphics card and a computer heat dissipation structure as described in any of the technical solutions of the first aspect of the present invention.

[0015] Optionally, the graphics card is detachably connected to the computer's heat dissipation structure.

[0016] Beneficial effects: 1. Through the above technical solution, firstly, when the graphics card is running, the heat generated by the computer heat dissipation structure of the present invention will be carried away by the air entering through the ventilation holes. Furthermore, the air will pass through the top (i.e., the fan side) and bottom (i.e., the fanless side) of the graphics card in sequence, which can not only effectively dissipate heat from the top of the graphics card, but also effectively dissipate heat from the bottom of the graphics card, thus effectively ensuring the heat dissipation effect.

[0017] Secondly, due to the cover design, the graphics card, apart from the display structure connecting to the monitor and the bus interface connecting to the motherboard (to facilitate graphics card wiring), only comes into contact with the external environment through ventilation holes and the second cavity. Furthermore, when the graphics card is in normal use, the second cavity is open downwards, making it difficult for dust in the air to enter the first cavity or the graphics card area along the second cavity. At the same time, the ventilation holes are set at an angle, making it difficult for dust in the air to enter the first cavity or the graphics card area through the ventilation holes. This effectively prevents dust from accumulating on the surface of the graphics card or the graphics card fan when the computer is not in use, thus effectively ensuring the heat dissipation effect and heat dissipation capacity of the graphics card.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0024] like Figures 1 to 6 As shown, a computer heat dissipation structure 101 for heat dissipation of a graphics card 102 includes a combined plate 1 and a sealing plate 2. The combined plate 1 is formed into a U-shaped structure, including a first plate 11 and a second plate 12 disposed opposite to each other, and a third plate 13 connected between the first plate 11 and the second plate 12. The U-shaped structure is used to accommodate the graphics card 102. The sides of the first plate 11, the second plate 12, and the third plate 13 near the graphics card 102 are respectively recessed inward to form a first cavity 111, a second cavity 121, and a third cavity 131 that are interconnected. The second cavity 121 is connected to the outside. The sealing plate 2 is connected to the combined plate 1 and is used to abut against one end of the graphics card 102 that is away from the display interface 1021. The first plate 11 is used to cover the fan surface of the graphics card 102. The first plate 11 has several inclined ventilation holes 112 on the side near the graphics card 102. The ventilation holes 112 include a first end 1121 and a second end 1122 that are arranged opposite to each other. The first end 1121 is connected to the first cavity 111 and the first cavity 111 is connected to the outside through the ventilation holes 112. The first end 1121 is closer to the third plate 13 than the second end 1122.

[0025] Through the above technical solution, firstly, when the graphics card 102 is running, the heat generated by the computer heat dissipation structure 101 of the present invention will be carried away by the air entering through the ventilation hole 112. Furthermore, the air will pass through the top (i.e. the fan side) and bottom (i.e. the fanless side) of the graphics card 102 in sequence, which can not only effectively dissipate heat from the top of the graphics card 102, but also effectively dissipate heat from the bottom of the graphics card 102, thus effectively ensuring the heat dissipation effect.

[0026] Secondly, due to the cover design, apart from the display structure for connecting to the monitor and the bus interface 1022 for connecting to the motherboard (to facilitate the wiring of the graphics card 102), the graphics card 102 only comes into contact with the external environment through the ventilation hole 112 and the second cavity 121. Furthermore, when the graphics card 102 is in normal use, the second cavity 121 is open downwards, making it difficult for dust in the air to enter the first cavity 111 or the area of ​​the graphics card 102 along the second cavity 121. At the same time, the ventilation hole 112 is set at an angle, making it difficult for dust in the air to enter the first cavity 111 or the area of ​​the graphics card 102 through the ventilation hole 112. This effectively prevents dust from accumulating on the surface of the graphics card 102 or the graphics card 102 fan when the computer is not in use, thus effectively ensuring the heat dissipation effect and heat dissipation capacity of the graphics card 102.

[0027] Please see Figure 6 The following is combined Figure 6 The process of cooling the graphics card 102 by the computer heat dissipation structure 101 of the present invention during operation will be described.

[0028] When the graphics card 102 is working, its fan will rotate (at the same time, the cooling fan inside the computer case will also guide the airflow so that the heat can be dissipated outside the case in a timely manner). At this time, air will enter the first cavity 111 through the ventilation hole 112 on the first plate 11, and be guided by the graphics card 102 fan. Then, it will pass through the third cavity 131 and the second cavity 121 in sequence, and be discharged from the second cavity 121. During this process, the air will pass through the top of the graphics card 102 (the fan side, i.e., the top of the fan side). Figure 6 The side closest to the first plate 11) and the bottom (non-fan side, i.e. Figure 6 (The side closest to the second plate 12) can effectively dissipate heat from the top and bottom of the graphics card 102, thus ensuring effective heat dissipation.

[0029] In one embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 6 As shown, the end of the first plate 11 of the present invention that is away from the third plate 13 can be configured to be flush with the end face of the graphics card 102.

[0030] In this embodiment, the first plate 11 can completely cover the top of the graphics card 102, preventing dust in the air from entering the first cavity 111 or the area of ​​the graphics card 102 from other areas, thus more effectively ensuring the heat dissipation effect and heat dissipation capacity of the graphics card 102.

[0031] In one embodiment of the present invention, such as Figure 2 and Figure 6 As shown, the second plate 12 of the present invention can be configured such that the distance between the end of the second plate 12 away from the third plate 13 and the end of the graphics card 102 having the bus interface 1022 is less than or equal to 2 cm.

[0032] Thus, in this embodiment, the second plate 12, which is arranged in this way, can not only effectively reduce its space occupation to avoid spatial conflicts with other structures or components inside the chassis, but also ensure the cross-sectional area of ​​the air outlet and ensure smooth airflow.

[0033] In one embodiment of the present invention, such as Figure 2 As shown, in the direction from the second end 1122 to the first end 1121, the radial dimension of the ventilation hole 112 gradually decreases.

[0034] Thus, due to the reduced diameter design of the ventilation holes 112, when the computer is not in use, dust is less likely to remain inside the ventilation holes 112 or enter the first cavity 111 or the graphics card 102 area through the ventilation holes 112, thereby further improving the dust prevention effect. At the same time, the reduced diameter design can increase the airflow velocity and reduce the temperature, thereby further improving the heat dissipation effect of the graphics card 102 when the computer is in use.

[0035] In one embodiment of the present invention, such as Figure 1 and Figure 5 As shown, the computer heat dissipation structure 101 of the present invention may further include a dust reduction component 3, which includes a plurality of cylindrical mesh structures 31. The shape of the cylindrical mesh structures 31 is adapted to the ventilation holes 112, and the plurality of cylindrical mesh structures 31 are respectively used to be installed in the plurality of ventilation holes 112.

[0036] In this way, the cylindrical mesh structure 31 can effectively filter the air flowing through the ventilation holes 112, thereby preventing excessive impurities or dust from entering the first cavity 111 and ensuring the dustproof effect.

[0037] In one embodiment of the present invention, such as Figure 1 and Figure 5As shown, the dust reduction component 3 of the present invention may further include two mounting posts 32 and several connectors 33. The two ends of each pair of adjacent cylindrical mesh structures 31 are respectively connected to the two connectors 33. The two mounting posts 32 are disposed on the first plate 11 and / or the sealing plate 2. The mounting posts 32 are used to be detachably connected to the connectors 33.

[0038] In this way, when the tubular mesh structure 31 needs to be installed, it can be installed stably and reliably using the connector 33 and the mounting post 32. When it needs to be disassembled, it can also be disassembled using the connector 33 and the mounting post 32, which is very convenient for replacement, cleaning and maintenance.

[0039] In one embodiment of the present invention, such as Figure 2 , Figure 3 and Figure 6 As shown, the computer heat dissipation structure 101 of the present invention may further include a dust blocking component 4 disposed in the second cavity 121. The dust blocking component 4 includes a first dust blocking plate 41 and a second dust blocking plate 42 disposed at intervals. The two ends of the first dust blocking plate 41 and the second dust blocking plate 42 are respectively connected to the second plate 12 and the sealing plate 2. The first dust blocking plate 41 and the second dust blocking plate 42 are disposed perpendicular to each other. Furthermore, in the direction from the third plate 13 to the graphics card 102, the projection of the first dust blocking plate 41 and the projection of the second dust blocking plate 42 are in contact with each other.

[0040] In this way, the dust-blocking component 4, when the computer is not in use, can effectively prevent dust in the air from entering the first cavity 111 or the graphics card 102 area through the second cavity 121, thereby avoiding the problem of dust accumulation on the graphics card 102. When the computer is in use, the dust-blocking component 4, in this way, will not affect the normal airflow, that is, it will not affect the normal heat dissipation process of the graphics card 102.

[0041] In one embodiment of the present invention, the shortest distance between the first dust barrier plate 41 and the second dust barrier plate 42 is greater than or equal to 0.8 cm.

[0042] In this embodiment, the shortest distance between the first dust blocking plate 41 and the second dust blocking plate 42 should not be too small, as this will affect the normal exhaust of air. Therefore, in an exemplary embodiment of the present invention, the shortest distance is set to 0.8 cm, which can effectively achieve the dust blocking effect without affecting the normal heat dissipation process of the graphics card 102.

[0043] According to a second aspect of the present invention, see also Figure 1 and Figure 2 A computer structure 100 is also provided, including a graphics card 102 and a computer heat dissipation structure 101 as described in any of the technical solutions of the first aspect of the present invention.

[0044] When the graphics card 102 is running, the heat generated by the graphics card 102 is carried away by the air entering through the ventilation hole 112. The air passes through the top and bottom of the graphics card 102 in sequence, which can effectively dissipate heat not only at the top of the graphics card 102, but also at the bottom of the graphics card 102, thus effectively ensuring the heat dissipation effect.

[0045] Meanwhile, due to the cover design, apart from the display structure connecting to the monitor and the bus interface 1022 connecting to the motherboard, the graphics card 102 only comes into contact with the external environment through the ventilation holes 112 and the second cavity 121. Furthermore, when the graphics card 102 is in normal use, the second cavity 121 is open downwards, making it difficult for dust in the air to enter the first cavity 111 or the graphics card 102 area along the second cavity 121. At the same time, the ventilation holes 112 are set at an angle, making it difficult for dust in the air to enter the first cavity 111 or the graphics card 102 area through the ventilation holes 112. This effectively prevents dust from accumulating on the surface of the graphics card 102 or the graphics card 102 fan when the computer is not in use, thus effectively ensuring the heat dissipation effect and heat dissipation capacity of the graphics card 102.

[0046] In one embodiment of the present invention, the graphics card 102 is detachably connected to the computer heat dissipation structure 101.

[0047] In this way, by setting the graphics card 102 and the computer heat dissipation structure 101 to be detachably connected, the versatility and adaptability of the computer heat dissipation structure 101 of the present invention can be effectively increased, enabling the computer heat dissipation structure 101 of the present invention to be adapted to more sizes or models of graphics cards 102, thereby improving versatility and convenience.

[0048] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
