[0018] Example 1

[0019] like Figures 1-5 As shown in the figure, this embodiment proposes an adjustable graphics card cooling device, which is installed on the side of a chassis 100. The side of the chassis 100 has an opening 101. The adjustable graphics card cooling device includes an exhaust component and a mounting component. The adjustable graphics card cooling device is installed at the opening 101 by the mounting component. The exhaust component is roughly facing the side of the graphics card, and hot air inside the chassis 100 is exhausted outward through the opening 101 to achieve auxiliary cooling.

[0020] The exhaust assembly comprises a plurality of fans 4 arranged horizontally and side by side, and two baffle plates 2 connected to the upper and lower sides of the plurality of fans 4 respectively. The baffle plate 2 comprises a limiting plate portion 23, an L-shaped guide plate portion 24, and two sliding plate portions 21 and two reinforcing plate portions 22 connected to the transverse ends of the guide plate portion 24 respectively. The guide plate portion 24 of the upper baffle plate 2 of the fan 4 is arranged in a normal L shape, and the guide plate portion 24 of the lower baffle plate 2 of the fan 4 is arranged in an inverted L shape, and the horizontal extension portion is arranged towards the inner side of the cabinet 100. The sliding plate portion 21 and the reinforcing plate portion 22 are arranged vertically, and the sliding plate portion 21 and the reinforcing plate portion 22 are perpendicular. The limiting plate portion 23 is horizontally connected to the end portions of the sliding plate portion 21, the reinforcing plate portion 22 and the guide plate portion 24.

[0021] For the specific installation position of the fan 4, the plurality of fans 4 are installed at the end face of the guide plate portion 24, that is, the bottom guide plate portion 24 of the upper baffle plate 2 and the top guide plate portion 24 of the lower baffle plate 2, and the plurality of fans 4 are installed in the middle by the two baffle plates 2 on both sides.

[0022] The mounting assembly comprises two mounting columns 1 arranged symmetrically with respect to the exhaust assembly. The mounting column 1 has a clamping plate portion clamped in the opening 101, which can be clamped in the opening 101 by clamping or installed by bolt connection. The two mounting columns 1 are arranged vertically and are respectively arranged on the transverse sides of the opening 101. The mounting column 1 has a sliding channel for the vertical sliding of the baffle plate 2, and the sliding channel is for the vertical sliding of the sliding plate portion 21. The reinforcing plate portion 22 is attached to the side of the clamping plate portion of the mounting column 1. After the baffle plate 2 is attached to the side of the two mounting columns 1 on the transverse sides respectively, the two mounting columns 1 can be aligned and clamped in the opening 101 of the cabinet 100 by the clamping plate portion.

[0023] As shown in Figure 1 The mounting column 1 is threadedly connected with a threaded knob 3 having an end portion abutting against the surface of the fan 4. When the exhaust assembly is mounted on the mounting column 1, the two sliding plate portions 21 on the side of the baffle plate 2 are clamped into the sliding channels of the two mounting columns 1 on both sides, and then the threaded knob 3 is tightened, the threaded knob 3 abuts against the side of the fan 4 to realize the abutting positioning of the exhaust assembly, and the threaded knob 3 specifically abuts against the frame of the fan 4. After the subsequent installation of the heat dissipation device on the cabinet 100, even if the threaded knob 3 loosens, the limiting plate portion 23 can prevent the exhaust assembly from falling off the mounting column 1. The mounting column 1 is provided with a wind speed adjusting switch 41 for adjusting the rotating speed of the fan 4. After the exhaust assembly is mounted on the mounting column 1, the wind speed adjusting switch 41 electrically connected with the fan 4 is mounted on the mounting column 1, and the rotating speed of the fan 4 is adjusted by rotating the wind speed adjusting switch 41. The threaded knob 3 and the wind speed adjusting switch 41 are both arranged towards the outside of the opening 101, which is convenient for the user to operate from the outside.

When the computer host runs, the heat dissipation device exhausts hot air from the side of the case 100, the exhaust is smooth, the heat dissipation effect is improved, and the service life of the display card is effectively guaranteed.

[0025] Embodiment two

[0026] As Figures 1-5 shown, the adjustable display card heat dissipation device provided in the embodiment, compared with the first embodiment, in the embodiment, the louver is installed outside the fan 4 between the two installation columns 1, the louver includes the fixed plate 5 connected to the side of the installation column 1, the rotating rod horizontally and dampingly arranged on the fixed plate 5 and arranged side by side in the vertical direction, the multiple window plates 6 one by one corresponding installed on the multiple rotating rods and the linkage plate 7 vertically distributed and rotationally connected with the multiple window plates 6. The side of the linkage plate 7 has a rotating rod part, the front side of the window plate 6 has a boss rotationally connected with the rotating rod part, forming a parallelogram structure. The user can only drive the multiple window plates 6 to rotate synchronously by pushing and pulling the linkage plate 7, adjust the size of the air vent between the multiple window plates 6, and also can adjust the ventilation direction. After the window plate 6 is adjusted, because of the damping effect between the fixed plate 5 and the rotating rod, the window plate 6 will remain in the adjusted position.

[0027] When the display card runs and ventilates and dissipates heat by using the heat dissipation device, the window plate 6 is adjusted to be inclined upward or horizontal, the fan 4 will exhaust the hot air in the case 100 along the inclined upward or horizontal air vent, rather than adjusting the window plate 6 to be inclined downward, preventing the fan 4 from blowing downward to the ground to cause dust. When the display card does not run and does not ventilate and dissipate heat by using the heat dissipation device, the multiple window plates 6 are adjusted to be inclined and fit each other, the louver is closed, preventing the dust and other impurities in the external air from entering the case 100 from here. For Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The width and number of the window plate 6 are only illustrative to clearly show the structure lines and the connection relationship between the structures, the actual width of the window plate 6 is larger, and the number is more, which can meet the demand of closing the louver by the multiple window plates 6.

[0028] In order to improve the convenience of adjusting the louver, the protrusion 8 is arranged on the front side of the linkage plate 7, the user operates by pushing and pulling or pinching the protrusion 8, drives the linkage plate 7 to move, drives the multiple window plates 6 to rotate synchronously by using the linkage plate 7, and realizes the adjustment of the size of the air vent of the louver.

[0029] In the embodiment, the opening 101 is closed when not in use to prevent dust from entering the case 100 through the opening 101.

[0030] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to this, and various changes can be made within the knowledge range possessed by the technical personnel in the technical field without departing from the purpose of the utility model.
