Description

Technical Field

[0001] This utility model relates to the field of heat dissipation in electronic devices, and in particular to a concealed fan connection structure. Background Technology

[0002] Cooling fans have a wide range of uses, but because they are usually installed inside machines and not easily noticed, they are not very common. Modern electronic products all require cooling fans to dissipate heat and lower temperatures, so it's important to understand their applications. Cooling fans are commonly used in automotive electronics, computer accessories, printers, fax machines, banner printers, medical instruments, power systems, electric vehicle chargers, network cabinets, transformers, industrial control systems, stage lighting, new energy sources, telecommunications, frequency converters, engines, and instrumentation, among many others.

[0003] The principle of a cooling fan: The radiator is a major part of the cooling system, designed to protect the machine from damage caused by overheating. The radiator works by using cool air to lower the temperature of the coolant inside the radiator that comes from the heat source.

[0004] Cooling fans for electronic devices are often made by connecting two or three individual fans together and then combining them with heat sink fins, depending on different cooling requirements. The existing fan connection methods are generally located on the front, mating surface, or side. If the splicing mechanism could be placed on the back of the fan, it would be better hidden and would preserve and improve the integrity and aesthetics of the front and side.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
