Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a computer chassis structure with a side-mounted fan and positive pressure airflow duct. Background Technology

[0002] Effective heat dissipation for graphics cards ensures that the heat generated during operation is quickly and efficiently dissipated, thus guaranteeing the stability and lifespan of the graphics card. Graphics cards typically generate a significant amount of heat during demanding games or high-load graphics processing tasks. Inadequate cooling can lead to overheating, causing crashes, freezes, and other problems, severely impacting the gaming or graphics processing experience.

[0003] When the graphics card is running, other components in the computer case also generate heat and hot air. If the hot air generated by these components is drawn into the components as if it were cold air, it will lead to poor heat dissipation.

[0004] See Figure 1 This diagram illustrates the airflow design of a standard computer case; the case itself is hidden for ease of observation. The case has top, bottom, front, and rear fans. Cool air enters from the bottom and front, while hot air is exhausted from the top and rear. The arrows indicate the airflow direction. Hot air from the graphics card is exhausted from the sides and rear. The hot air from the sides is partially obstructed by the case casing and drawn in by the negative pressure from the rear and top exhaust fans, passing through the memory and CPU before being expelled. Almost all the hot air exhausted from the rear of the graphics card passes through the memory and CPU before being expelled. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of prior art and provide a chassis structure that utilizes positive pressure cooling inside the chassis.

[0006] To achieve the above objectives, this utility model provides a computer chassis structure with a side-mounted fan and positive pressure airflow, including a chassis, a fan installed inside the chassis, and further comprising:

[0007] A side-mounted fan is located inside the chassis, on the right side of the CPU and CPU cooler, and above the graphics card.

[0008] Two graphics card baffles are provided. The graphics card baffles are located below the exhaust vents of the graphics card and are fixedly connected to the chassis. The graphics card baffles are used to isolate the hot and cold air channels of the graphics card.

[0009] The side-mounted fan works in conjunction with the main fan to create positive pressure inside the chassis.

[0010] Preferably, the fan includes an upper fan, a lower fan, a front fan, and a rear fan. The upper fan is located on the top of the chassis, the lower fan is located on the bottom surface of the chassis, and the front fan and the rear fan are located on the front and rear sides of the chassis, respectively.

[0011] Preferably, the chassis surface is provided with a first graphics card exhaust vent and a second graphics card exhaust vent at the corresponding position of the graphics card.

[0012] Preferably, the first graphics card exhaust port and the second graphics card exhaust port are respectively located on the front and rear sides of the chassis, and the upper part of the first graphics card exhaust port is also provided with a side fan air inlet, which is also located on the surface of the chassis.

[0013] Preferably, the graphics card baffle is used to assist the hot air generated by the graphics card to be discharged from the first graphics card exhaust port and the second graphics card exhaust port.

[0014] Compared with the prior art, the technical solution proposed in this application has the following beneficial effects: by setting a side fan, the airflow channels of the CPU and graphics card inside the computer case are isolated and do not interfere with each other, thus improving the heat dissipation efficiency; by using positive pressure heat dissipation inside the case, the positive pressure blocks the hot air from the graphics card from entering the CPU and memory, and by using the Bernoulli effect to guide the airflow direction inside the case at the openings in the case shell, the heat dissipation of the CPU and graphics card is optimized, and the stability of the case operation is improved.
