Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

In the description of the present application, it is to be understood that the features of the terms "first", "second" may explicitly or implicitly include one or more of the features.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

With the development of smart phones, especially the popularization and application of 5G, the power consumption of the whole phone is increased. Compared with the current equipment, the heat consumption of the 5G intelligent terminal equipment is increased by more than 50%, and a more efficient heat dissipation solution needs to be sought urgently.

In order to solve the current situation, a fan is adopted in the current radical solution, that is, a miniature centrifugal fan is installed inside the mobile phone to perform air cooling and heat dissipation. Due to the fact that noise and dustproof performance of the air-cooled heat dissipation device are poor, wind resistance is high, air-cooled heat dissipation performance is not obvious, and heat dissipation effect is poor. In addition, in terms of reliability, in a long-term dust test, the fan is locked, namely the stop operation fails. If the fan self locked-rotor protection design is improper, the fan self generates heat and burns out even if the fan is locked-rotor for a long time, and the user experience is greatly influenced. The fan blade rotating type fan has a considerable volume of the apparatus even if it is miniaturized, and requires a considerable installation space for installation. At present, fan blade rotating type fans are still commonly used in the heat dissipation system of the traditional notebook computer, but for thin mobile phones or watches, etc., due to the limitation of the device structure size, the minimum known fan is 17 × 3.5mm, the fan blade rotating type fan is difficult to meet the requirements, so that the heat generated during the operation of the device is difficult to rapidly dissipate, the operation performance of the device is affected, and even if the fan blade rotating type fan is forcibly designed, the space of other structural components is sacrificed, such as 1 to 2 camera assemblies, etc., are removed.
