[0040] The utility model provides a kind of computer host 1.

[0041] Please refer to Figures 1 to 2 In an embodiment of the utility model, the computer host 1 includes a case 10, a mainboard 20, a processor 30 and a display card 40. The case 10 has an air inlet 121, an air outlet 111 and a heat dissipation air duct connecting the air inlet 121 and the air outlet 111. The case 10 includes a bottom plate 12 and a top plate 11 arranged oppositely along a first direction. One of the top plate 11 and the bottom plate 12 is provided with the air inlet 121, and the other is provided with the air outlet 111. The mainboard 20 is arranged in the heat dissipation air duct. The processor 30 is arranged on the mainboard 20. The display card 40 is arranged on the mainboard 20 and spaced apart from the processor 30. The display card 40 and the processor 30 are both projected away from the first direction and fall on the bottom plate 12 and are spaced apart.

[0042] The computer host 1 in the technical solution of the utility model includes a case 10, a mainboard 20, a processor 30 and a display card 40. The case 10 has an air inlet 121, an air outlet 111 and a heat dissipation air duct connecting the air inlet 121 and the air outlet 111. When the case 10 is in use and the internal heat dissipation devices are running, external air flows into the heat dissipation air duct through the air inlet 121, then flows through the heat dissipation air duct to the air outlet 111 and is discharged through the air outlet 111, realizing air cooling heat dissipation. In this embodiment, the case 10 includes a bottom plate 12 and a top plate 11 arranged oppositely along a first direction. One of the top plate 11 and the bottom plate 12 is provided with the air inlet 121, and the other is provided with the air outlet 111. For convenience of description, the air inlet 121 is arranged on the bottom plate 12, and the air outlet 111 is arranged on the top plate 11. Regarding the first direction, as shown in the figure, Figure 1 or Figure 2As shown, the direction refers to the direction from the bottom plate 12 to the top plate 11, that is, the direction from the bottom end to the top end of the case 10, and no further limitation is made. In order to prevent the cooling air flowing through the processor 30 and the graphics card 40 arranged on the mainboard 20 from affecting each other, in the embodiment, the processor 30 and the graphics card 40 arranged on the mainboard 20 are arranged in a spaced manner, and it is required that the projections of the graphics card 40 and the processor 30 on the bottom plate 12 in the direction away from the first direction are also arranged in a spaced manner, that is, the projections of the graphics card 40 and the processor 30 on the bottom plate 12 in the direction from the top plate 11 to the bottom plate 12 are arranged in a spaced manner. In this way, when the external cooling air enters the cooling air duct through the air inlet 121 of the bottom plate 12 and flows in the first direction to the air outlet 111, the cooling air flowing through the processor 30 on the mainboard 20 will be discharged in the first direction to the air outlet 111 after cooling the processor 30, and the cooling air flowing through the graphics card 40 on the mainboard 20 will also be discharged in the first direction to the air outlet 111 after cooling the graphics card 40. Therefore, in the embodiment, when the case 10 is in use, the first air current carrying heat formed after the cooling air completes the cooling of the processor 30 on the mainboard 20 will be directly discharged through the air outlet 111 and will not affect the cooling of the graphics card 40 arranged in a spaced manner with the processor 30. Similarly, the second air current carrying heat formed after the cooling air completes the cooling of the graphics card 40 on the mainboard 20 will also be directly discharged through the air outlet 111 and will not affect the cooling of the processor 30 arranged in a spaced manner with the graphics card 40. Through such arrangement, when the cooling air flows through the cooling air duct to cool the processor 30 and the graphics card 40 on the mainboard 20 in actual use of the case 10, the two air currents carrying heat formed after the cooling of the processor 30 and the graphics card 40 will be directly discharged through the air outlet 111. In this way, the mixing of heat during the cooling of the processor 30 and the graphics card 40 arranged on the mainboard 20 in the cooling air duct can be eliminated, so that the cooling effect of the processor 30 and the graphics card 40 is improved, and the overall cooling effect of the computer host 1 is improved.

[0043] In an embodiment, as shown in Figure 2 the graphics card 40 is arranged in a spaced manner with the processor 30 in the second direction, and the second direction intersects the first direction. In the embodiment, the graphics card 40 is arranged in a spaced manner with the processor 30 in the second direction. Regarding the second direction, as shown in Figure 2As shown, the second direction refers to the direction from the back of the case 10 to the front of the case 10, the back refers to the side away from the user, and the front refers to the side facing the user, the second direction is perpendicular to the first direction, that is, the processor 30 and the graphics card 40 are arranged in a spaced manner along the second direction in the heat dissipation air duct of the case 10, which has the same effect as the above-mentioned embodiment. In this embodiment, since the graphics card 40 is vertically installed along the first direction and is arranged close to the front of the case 10, assuming that the front of the case 10 is transparent, the graphics card 40 can not only have good heat dissipation effect, but also can be better displayed in front of the user. In other embodiments, assuming that the length of the case 10 along the second direction is long enough, and the graphics card 40 is arranged on the mainboard 20 along the second direction and is spaced apart from the processor 30 on the mainboard 20, the graphics card 40 and the processor 30 can also have good heat dissipation effect, and the installation manner of the graphics card 40 is not limited.

[0044] In an embodiment, as shown in Figure 2 and Figure 5 The computer host 1 further comprises a mounting frame 50, the mounting frame 50 is arranged in the case 10, and at least part of the mounting frame 50 is located between the graphics card 40 and the case 10, the mounting frame 50 has a mounting groove 541 for mounting the graphics card 40. In this embodiment, the above-mentioned embodiment is taken as an example to illustrate the vertically installed graphics card 40 along the first direction. Since the graphics card 40 is only installed on the mainboard 20 by plugging and is unstable, in order to stably install the graphics card 40 in the case 10, the computer host 1 further comprises a mounting frame 50, the mounting frame 50 is detachably mounted in the case 10, and at least part of the mounting frame 50 is arranged between the graphics card 40 and the bottom plate 12, the mounting frame 50 is provided with a mounting groove 541 for the graphics card connector seat 41 of the graphics card 40 to pass through and install, in this embodiment, the mounting frame 50 can be the bottom plate 12, or can be a separate accessory, and the mounting frame 50 is not limited.

[0045] In an embodiment, as shown in Figure 3As shown in Figure 4, the mounting bracket 50 is spaced apart from the base plate 12 along the first direction, forming a mounting space 14 between the mounting bracket 50 and the base plate 12. The mounting space 14 is used for laying external connectors of the graphics card 40 and / or the motherboard 20. In this embodiment, the mounting bracket 50 is a separate accessory. The mounting bracket 50 is spaced apart from the base plate 12 of the chassis 10 along the first direction, thereby forming a mounting space 14 at the bottom of the chassis 10. Since the motherboard connector 21 of the motherboard 20 and the graphics card connector 41 of the graphics card 40 are both facing the base plate 12 of the chassis 10, in order to facilitate cable routing, in this embodiment, the mounting bracket 50 is used to further support the graphics card 40 and facilitate the laying of external connectors or cables connecting the graphics card 40 and / or the motherboard 20.

[0046] In one embodiment, such as Figures 2 to 4 As shown, the computer host 1 also includes a partition 60, which is disposed on the base plate 12 and located within the installation space 14. The partition 60 divides the installation space 14 into a cable routing cavity 142 and a fan mounting cavity 141. The cable routing cavity 142 is used for laying external wiring, and the fan mounting cavity 141 is used for installing a cooling fan. The fan mounting cavity 141 is located at the air inlet 121. To improve the heat dissipation of the computer host 1, in this embodiment, the computer host 1 further includes a partition 60, which is detachably disposed on the base plate 12 and located within the installation space 14. The partition 60 mainly serves to divide the installation space 14 into a cable routing cavity 142 and a fan mounting cavity 141, wherein, as... Figure 2 As shown, the partition 60 is disposed on the base plate 12 and partially encloses the chassis 10 to form a cable routing cavity 142. This cable routing cavity 142 is mainly used for cable laying in the above embodiment. In this embodiment, a through hole for cable to pass through is provided on the back of the chassis 10. Furthermore, the partition 60 disposed on the base plate 12 and partially encloses the chassis 10 to form a fan mounting cavity 141 for mounting a cooling fan. The fan mounting cavity 141 is formed on the base plate 12, that is, directly above the air inlet 121. Therefore, when the cooling fan is installed in the fan mounting cavity 141, the suction force of the chassis 10 to the external cooling airflow can be further improved, thereby further improving the heat dissipation effect of the chassis 10. In this embodiment, the partition 60 can be integrally bent or integrally cast with the base plate 12, without much limitation. Furthermore, multiple cooling fans can be provided, and the multiple cooling fans are arranged sequentially along the second direction. There is no specific limitation on the number of cooling fans.

In order to enable the mounting rack 50 to be stably mounted on the case 10, in the embodiment, the mounting rack 50 includes a first connecting portion 51 and a second connecting portion 52 disposed on opposite sides, and the opposite sides of the case 10 are also provided with fixing holes 10a corresponding to the first connecting portion 51 and the second connecting portion 52, where the opposite sides refer to the left and right sides of the case 10, that is, the mounting rack 50 is detachably disposed in the corresponding fixing holes 10a, and in the embodiment, the case 10 further includes a support plate disposed in the interior, which is mainly used for mounting the mainboard 20, and the support plate is also disposed in the case 10 to form a cavity for accommodating the switch device, wherein the fixing holes 10a are disposed on the support plate and the bottom plate 12, that is, the first connecting portion 51 and the second connecting portion 52 of the mounting rack 50 are respectively mounted on the support plate and the bottom plate 12. In another embodiment, in the embodiment, three mounting grooves 541 are disposed on the mounting rack 50 along the second direction, in order to enable the mounting rack 50 to be adjusted according to the actual size of the graphics card 40 and the specific position of the graphics card 40 mounted on the mainboard 20, the number of the fixing holes 10a is multiple, and multiple fixing holes 10a are respectively disposed on the opposite sides of the case 10 and are spaced apart along the second direction, and the fixing holes 10a disposed on the opposite sides are one-to-one corresponding, so that the mounting rack 50 can be fixedly mounted on the appropriate position according to the actual situation, and such arrangement can also reduce the influence of the mounting rack 50 on the airflow entering through the air inlet 121.

[0048] In an embodiment, as Figure 5As shown, the mounting bracket 50 includes a first connecting segment 54 and a second connecting segment 55 connected to each other. The first connecting portion 51 is located on the side of the first connecting segment 54 away from the second connecting segment 55, and the second connecting portion 52 is located on the side of the second connecting segment 55 away from the first connecting segment 54; and / or, the connection between the first connecting segment 54 and the second connecting segment 55 is bent. In this embodiment, the mounting bracket 50 includes a first connecting segment 54 and a second connecting segment 55, wherein the first connecting portion 51 is located at the end of the first connecting segment 54 away from the second connecting segment 55, and the second connecting portion 52 is located at the end of the second connecting segment 55 away from the first connecting segment 54. Both the first connecting portion 51 and the second connecting portion 52 are folded edges, which extend away from the first direction. A hole is provided on the folded edge, which corresponds to the aforementioned fixing hole 10a. In another embodiment, the connection between the first connecting segment 54 and the second connecting segment 55 is bent, and the second connecting segment 55 is gradually inclined downwards from the left to the right side of the chassis 10 relative to the first connecting segment 54. This improves the aesthetics of the mounting bracket 50 supporting the graphics card 40 when the front of the chassis 10 is transparent.

[0049] Furthermore, the mounting bracket 50 also includes a third connecting portion 53, which is located on the side of the first connecting segment 54 near the second connecting segment 55. The third connecting portion 53 is used to connect with the graphics card 40. To facilitate the fixed installation of the mounting component with the graphics card 40, in this embodiment, the mounting bracket 50 further includes a third connecting portion 53, which is located on the side of the first connecting segment 54 near the second connecting segment 55. The third connecting portion 53 may be formed by bending a portion of the first connecting segment 54 away from the first direction, thereby forming a mounting opening and a connecting edge. During installation, the connecting end of the graphics card 40 can be inserted into the mounting opening, and then screws are used to sequentially pass through the connecting end of the graphics card 40 and fix it to the connecting edge. The setting of this mounting opening can also reduce the obstruction of the heat dissipation airflow by the mounting bracket 50, so that the cooling airflow is smoother.

[0050] In one embodiment, such as Figure 5 As shown, the mounting groove 541 is formed on the first connecting section 54; the second connecting section 55 is provided with a mounting hole 551 corresponding to the third connecting part 53. In order to facilitate the fixed connection between the graphics card 40 and the third connecting part 53 in the above embodiment, in this embodiment, a mounting hole 551 is formed on the second connecting section 55. Since the rubber of the second connecting section 55 is inclined to the first connecting section 54, the mounting hole 551 corresponds to the third connecting part 53 provided on the first connecting section 54 in the direction from the left side to the right side of the chassis 10. When the graphics card 40 is installed on the third connecting part 53, the mounting hole 551 allows tools to be easily inserted to fix the graphics card 40 on the third connecting part 53, thereby achieving a fixed connection with the mounting bracket 50.

Since the bottom plate 12 below the installation cavity is provided with an air inlet 121 and the top plate 11 above the installation cavity is provided with an air outlet 111, the installation cavity forms a heat dissipation air duct. In this embodiment, since the graphics card socket 41 and the mainboard socket 21 are both arranged towards the bottom plate 12, in order to facilitate the socket, in this embodiment, as shown in Figure 3As shown, an opening 122 is provided on the base plate 12. The opening 122 is mainly used for the insertion of the wire connecting the graphics card connector 41 and the motherboard connector 21.
