[0002] For the desktop computer host with independent display card, when display card runs in the case, it generates more heat. Independent display card has a cooling fan, which blows hot air outward. For the display card type that blows hot air from the side, the hot air blows against the side panel of the case, and it is not easy to discharge from the case. The display card has limited cooling effect, which can easily reduce the service life. INVENTION CONTENT
[0003] The utility model aims at the problems in the background art, and provides an auxiliary radiator for display card, which can assist the display card in cooling, improve the cooling effect, guide the hot air and discharge it to the outside of the case, and improve the service life of the display card.
[0004] The technical scheme of the utility model relates to an auxiliary radiator for display card, which comprises a flow guide frame, a fan module and a wind speed adjusting assembly. The flow guide frame is a "L"-shaped hollow shell structure with a baffle part on the top side, an internal flow channel, an air inlet on the upper part, and an air outlet on the side. The air inlet, flow channel and air outlet are connected in sequence. The fan module comprises a first fan arranged in the flow channel and a plurality of exhaust fans arranged at the air outlet. The first fan faces the exhaust fans. The wind speed adjusting assembly is arranged on the flow guide frame to control the start-stop and speed of the fan module.

[0017] like Figures 1-3 As shown in the figure, the graphics card auxiliary heat sink proposed in this embodiment includes a flow guide 1, a fan module and a fan speed adjustment component. The flow guide 1 is installed on the chassis, and the fan speed adjustment component controls the speed of the fan module to adjust the heat dissipation speed.
[0018] The airflow guide 1 has an "L"-shaped hollow shell structure with a baffle on the top side and an internal flow channel 102. The upper part has a long, narrow air inlet 101, allowing hot air to enter from a wide area. An air outlet 103 is located on the side, and the air inlet 101, flow channel 102, and air outlet 103 are sequentially connected. Cool air enters from the front of the graphics card, and hot air exits from the side. The baffle faces the side of the graphics card, blocking and limiting the hot air flow, allowing it to enter the flow channel 102 through the air inlet 101.
[0019] like Figure 1 and Figure 2As shown, the fan module includes a first fan 2 disposed within the airflow channel 102 and a second fan 3 and a third fan 4 disposed side-by-side at the air outlet 103. The first fan 2, the second fan 3, and the third fan 4 are sequentially mounted on the airflow guide 1. The first fan 2 faces the second fan 3. When the first fan 2, the second fan 3, and the third fan 4 are running, they create a negative air pressure within the airflow channel 102. Hot air from the side of the graphics card enters the airflow channel 102 through the air intake 101 and is blown towards the second fan 3 by the first fan 2. It is then blown out of the chassis by the second fan 3 and the third fan 4 towards the air outlet 103. The chassis has a heat dissipation opening corresponding to the air outlet 103.
[0020] The fan speed adjustment component is mounted on the air guide 1 and controls the start / stop and speed of the fan module. The fan speed adjustment component includes a temperature control module 5 and a manual adjustment switch 6. The temperature control module 5 includes a temperature sensor and a controller. The temperature sensor is located on the side of the air intake 101, specifically on the side of the graphics card, and can detect the temperature of the hot air exhausted from the side of the graphics card. The temperature sensor is communicatively connected to the controller, transmitting the detected temperature data to the controller. The controller is connected to the fan module control, and adjusts the fan speed accordingly; the higher the temperature detected by the temperature sensor, the higher the fan speed. The manual adjustment switch 6 is located at the air outlet 103 and is connected to the fan module control, allowing manual adjustment of the fan speed.
[0021] like Figure 1 and Figure 2 As shown, a mounting plate 7 is provided on the air guide frame 1. The mounting plate 7 is located at the air outlet 103. The mounting plate 7 has multiple screw holes (not shown). The chassis has through holes corresponding to the screw holes. By passing screws through the through holes and tightening them into the screw holes, the mounting plate 7 can be installed. Figure 3 The opening at the rear of the chassis is for exhausting hot air. A filter plate with mesh is installed at the opening, and the filter plate serves as part of the chassis for ventilation. Mounting plate 7 can be directly mounted on the filter plate or installed in other locations within the chassis. Figure 3 The diagram only schematically shows a portion of the chassis structure (excluding the structure of the part connecting to the mounting plate 7), thus enabling the installation of the air intake bracket 1. After the air intake bracket 1 is installed, the air inlet 101 is located on the side where the graphics card exhausts hot air.
[0022] In addition to installing the air guide 1 via the mounting plate 7, multiple threaded holes can also be directly provided on the air guide 1, and corresponding through holes can be provided on the chassis. Similarly, the air guide 1 can be directly installed by passing screws through the through holes and screwing them into the threaded holes of the air guide 1.
[0023] The upper sliding bracket 1 is equipped with a latch 8, and the bottom end of the latch 8 has a flexible locking platform. For example, the flexible locking platform can be a V-shaped flexible protrusion structure with the tip facing to the side. When sliding on the air guide bracket 1, it can undergo elastic deformation. When the flexible locking platform slides down from the slide rail on the air guide bracket 1, it rebounds and locks onto the air guide bracket 1. The front end of the latch 8 has a forward-protruding mounting plate, which can be placed on top of the graphics card to improve the operational stability of this auxiliary heatsink.
[0024] This embodiment can be installed on a computer case. The air intake 101 of the air guide bracket 1 is located on the side of the graphics card's hot air outlet. By detecting the air temperature on the side of the graphics card, the fan speed is adaptively adjusted. A negative air pressure is created in the airflow channel 102, drawing hot air from the side of the graphics card into the air intake 101. The hot air flows along the airflow channel 102 and is finally exhausted by the fan from the air outlet 103, assisting the graphics card in heat dissipation, improving the heat dissipation effect, and guiding and exhausting hot air to the outside of the computer case, thereby increasing the lifespan of the graphics card, reducing the operating temperature of other components inside the computer case, and improving the stability of the host system. Especially for computer cases in locations like oceanfront properties, the air guide bracket 1 can block and draw in hot air from the side of the graphics card, reducing the impact of hot air directly acting on the side glass of the computer case and reducing the probability of glass breakage.
[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
