Description

Heat dissipation external member and air pump thereof Technical Field The application relates to the technical field of air pump accessories, in particular to a heat dissipation sleeve and an air pump thereof. Background The compact size and the integrated fan blade heat dissipation structure of the small air pump have remarkable application value in space-limited scenes such as miniature electronic equipment and portable instruments. However, the air pump has two inherent defects in the operation process, namely, 1, noise pollution is prominent, air flow turbulence and air shearing effect generated by the exposed fan blade during high-speed rotation can cause high-frequency squeal, particularly resonance is easy to form in a cavity of the closed equipment, the application of the air pump in noise sensitive environments (such as medical equipment and mother and infant products) is severely restricted, 2, the heat dissipation efficiency is limited, the heat dissipation surface area is seriously insufficient due to miniaturization design, the heat exchange efficiency of forced convection by the fan blade is approximate to the physical limit, particularly under the continuous high-load working condition, the temperature rise curve of the air pump is steep, and the magnet demagnetizing risk and the service life attenuation of electronic elements are caused. The improvement scheme commonly adopted in the current industry comprises that a metal heat dissipation sleeve is additionally arranged, the heat conduction area can be enlarged, but the closed structure blocks the air flow path, so that the active heat dissipation capacity of the fan blade is weakened, and the problem of high-frequency noise cannot be solved. The scheme fails to cooperatively solve the contradiction between noise suppression and heat radiation enhancement, namely noise reduction measures often come at the expense of heat radiation efficiency, and the design of enhancing heat radiation amplifies noise radiation. Therefore, an innovative structure is needed to realize the synchronous jump of the heat dissipation performance and the noise characteristic of the air pump under the premise of ensuring the miniaturization advantage.
