Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer cases, and particularly relates to a convection cooling type computer case. BACKGROUND

[0002] A computer case is the outer shell of a computer hardware, used to accommodate and protect various hardware components inside the computer, such as the motherboard, graphics card, hard drive, etc. It is usually made of metal or plastic, has certain heat dissipation and dust prevention functions, and provides various interfaces and slots to facilitate the user to install and replace hardware devices. The design and size of the case will also affect the heat dissipation performance and expandability of the computer. Generally speaking, the computer case will also be equipped with power supply and fan components to ensure stable operation of the computer and maintain appropriate temperature. Computer case cooling refers to the process of reducing the temperature inside the computer case through various cooling methods. High temperature is one of the main enemies of computer hardware operation. Excessive temperature can cause computer performance degradation, stability problems and even hardware damage. The computer case often uses fans to introduce cold air into the case and exhaust hot air out of the case to maintain air circulation. There are usually multiple fans inside the case, such as front fans, rear fans and top fans. In the prior art, the computer case often uses multiple groups of cooling fans to cool the inside of the case, so that the heat inside the case exchanges with the outside air. If the ambient temperature is not much different from the temperature inside the case, the high-temperature gas inside the case is difficult to effectively exhaust after heat exchange with the outside environment under the action of the cooling fan.

[0003] In order to solve the above technical problems, the prior art discloses a convection cooling type computer case with publication number CN118567451A, which comprises a case body and a side plate installed in cooperation therewith. A plurality of cooling fans are installed on one side of the inside of the case body, and the plurality of cooling fans are combined by an installation frame, a driving motor and an impeller. A cooling pipe is arranged on one side of the plurality of cooling fans inside the case body. Specifically, the cooling pipe is made of brass material to better exchange heat. A circulating cylinder is fixed at the bottom end of one side of the inside of the case body, and a circulating cavity is formed in the inside of the circulating cylinder. A water wheel is rotatably connected in the circulating cavity. The driving motor of one of the cooling fans is fixed with a transmission shaft extending into the inside of the circulating cylinder, and the transmission shaft and the water wheel are fixedly connected.

[0004] Although the prior art scheme realizes the circulation of the cooling liquid inside the case main body, further ensures that the temperature of the gas entering the case main body can be further reduced, and improves the overall heat dissipation effect inside the case main body, when the air inlet is used for air inlet heat dissipation, some foreign impurities adsorbed by the air flow are easily accumulated at the air inlet, which needs to be cleaned by personnel in time, and the cleaning method is mostly manual cleaning by personnel holding a brush and other tools, which is time-consuming and laborious, increases the labor of personnel, and then affects the practicality of the device when used.
