Abstract

The invention provides a fan assembly and an electric device with the same. The fan assembly resolves the problem that noise is large in the existing electric device. The fan assembly comprises a first casing, a noise reduction material and a bladeless fan. A recessed portion with an opening is limited. The noise reduction material is arranged on the inner side or the outer side of the first casing. The bladeless fan further comprises a base and a fan head. The fan head is arranged in the recessed portion of the first casing, and the base is arranged on the outside of the first casing. A plurality of ventilation holes are arranged on the first casing, and the bladeless fan is used for producing negative pressure through first air flow blown by the fan head in the recessed portion of the first casing to enable second air flow to pass through the noise reduction material and the first casing and to be discharged through an opening of the recessed portion. The fan assembly adopts the noise reduction material to reduce or remove noise of the second air flow passing through the noise reduction material. The fan assembly and the electric device with the fan assembly have small noise.

Description

technical field [0001] The invention relates to the field of heat dissipation, in particular to a fan assembly and electrical equipment with the fan group. Background technique [0002] The interior of electrical equipment often includes heat-generating components. Therefore, it is necessary to dissipate heat from electrical equipment including heat-generating components. Generally, the heat dissipation system adopted may be an air cooling system or a liquid cooling system. Because the air-cooled heat dissipation system has the advantages of simple installation, reliable performance, easy maintenance and low cost, it is adopted by most electrical equipment. Of course, the air cooling system and the liquid cooling system can also be used in combination. [0003] In the field of medical imaging, related electrical equipment includes magnetic resonance imaging (magnetic resonance imaging, MRI) equipment, computer tomography (computer tomography, CT) equipment, X-ray imaging ...
