DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0029] Embodiment:

[0030] As shown in Figs. 1 to 3 The utility model embodiment proposes a double groove GPU wind increasing structure, including GPU air inlet upper cover 1, base 2 and air inlet mechanism 3.

[0031] The GPU air inlet upper cover 1 is three-section design with certain section difference, including upper cover air inlet section plane 4, upper cover air inlet section difference bevel 5 and upper cover air outlet section plane 6.

[0032] The air inlet mechanism 3 is installed in the air inlet end of the base 2, and is used to control the air inlet direction.

[0033] The GPU air inlet upper cover 1 is installed on the base 2, and cooperates with the base 2 to form a cavity except the air inlet and outlet.

[0034] In specific embodiments, the GPU installed on the mainboard works with heat dissipation, at this time the air inlet mechanism 3 draws air from the air inlet into the cavity formed between the GPU air inlet upper cover 1 and the base 2, the air first passes through the smaller air inlet section to increase the wind speed, and then enters the air outlet section. Because the air outlet section cavity is larger than the air inlet section cavity, the high-speed airflow rushes in and causes local pressure reduction, thereby actively drawing air from the air inlet section to maintain air pressure. At this time, the air flow and flow rate of the air outlet section are larger than those of the air inlet section, resulting in an air increase effect, thereby achieving increased air circulation during GPU heat dissipation and improved heat dissipation efficiency.

[0035] Further, the base 2 is provided with a base air inlet slope 7 at the air inlet end for increasing air intake.

[0036] When the high-speed airflow enters the low-pressure area and needs to draw in air, relying solely on the air provided by the air inlet mechanism 3 will cause the subsequent airflow to slow down, which cannot maintain the air increase effect for a long time. Therefore, a air inlet slope 7 is provided in the air inlet section of the base 2 to supplement the airflow and maintain the flow rate of the subsequent gas and the air increase effect.

[0037] Further, as shown in Fig. 2 , the upper cover air inlet section difference slope 5 is provided with a notch 8 for seamless connection with the raised slope part provided on the base 2.

[0038] The side surface of the upper cover air inlet section plane 4 and the upper cover air outlet section plane 6 is provided with a countersunk screw hole 9.

[0039] Specifically, as shown in Fig. 3 , the base 2 is provided with a threaded hole part 10 for cooperating with a screw 11 to fix the GPU air inlet upper cover 1.

[0040] When air is drawn from the air inlet mechanism 3 into the cavity formed between the GPU air inlet upper cover 1 and the base 2, it is necessary to ensure that air leakage does not occur during this process, which will reduce air transfer efficiency and thus reduce cooling efficiency. Therefore, the GPU air inlet upper cover 1 and the base 2 need to be tightly attached together through the screw 11, and at the same time, in order to facilitate installation, the notch 8 is provided on the upper cover air inlet section difference slope 5.

[0041] Further, a ventilation opening 12 is provided on the upper cover air inlet section plane 4, and the air inlet face of the air inlet mechanism 3 faces the upper cover air inlet section plane 4.

[0042] Since the air inlet mechanism 3 is arranged in the cavity between the upper cover air inlet section plane 4 and the base 2, in order to improve the air inlet performance of the air inlet mechanism 3, a ventilation opening 12 for guiding air into the cavity is needed to be provided on the upper cover air inlet section plane 4.

[0043] Specifically, the air inlet mechanism 3 includes a fan 13 and a wind wall 14.

[0044] The fan is installed at the air inlet section of the base 2, and the air wall 14 surrounds the fan 13.

[0045] The opening of the air wall faces the air outlet section of the base 2.

[0046] Since the air flow direction needs to be consistent during ventilation and heat dissipation, irregular turbulent air flow in the air flow direction is avoided to consume the internal energy of the air flow, thereby reducing the air flow rate, the fan 13 is needed to suck the air, and the air flow direction is consistent through the air wall 14 and the opening on the air wall 14, thereby enabling the air to smoothly form a low-pressure area and actively extract the air flow to increase the air flow.

[0047] Further, the air outlet section of the base 2 is provided with a heat dissipation module 15.

[0048] The heat dissipation module 15 is a block-shaped component composed of a plurality of heat dissipation fins, and the air duct opening between the heat dissipation fins faces the air outlet section of the base 2 at one end and faces the air inlet mechanism 3 at the other end.

[0049] In specific embodiments, it is difficult for the heat dissipation capacity of the GPU itself to completely contact the blowing air, thereby resulting in poor heat dissipation effect, and therefore, a heat dissipation module directly contacting the GPU is needed to guide the heat and increase the contact area of the air flow through the heat dissipation fins to improve the heat dissipation effect. At the same time, in order to maximize the contact of the air with more heat dissipation fins, the air duct between the heat dissipation fins needs to face the air outlet of the air inlet mechanism 3, and the windward surface needs to be inclined to maintain the high-speed flow of the gas and maximize the effect of the air increasing structure.

[0050] Compared with the prior art, the utility model has at least the following beneficial effects.

[0051] The utility model discloses a three-section type GPU air inlet upper cover and a base matched with the upper cover, which form a three-section type cavity air duct, increase the air volume through the increase of the cross-sectional area of the cavity structure when the cooling air is transmitted, and improve the cooling efficiency. Meanwhile, the three-section type GPU air inlet upper cover can ensure a large distance between the air inlet ends when the double-groove GPU is densely arranged, thereby avoiding the small air inlet caused by the small distance and affecting the heat dissipation effect. Finally, the air inlet inclined surface arranged on the base can also increase the air inlet surface and reduce the operating pressure of the fan, thereby providing a reliable source for the air volume and air pressure of the fan and prolonging the service life of the fan.

[0052] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
