Abstract

The invention discloses a cooling fan for a notebook computer, comprising: an upper cover plate, a metal base plate and an impeller located between the upper cover plate and the metal base plate, the blades of the impeller are arc-shaped in the radial direction, and the The height of the blades of the impeller increases gradually from the side close to the hub to the side away from the hub; the inner wall of the strip-shaped through hole of the metal base plate is provided with several pairs of arc-shaped branches at intervals, and two arc-shaped branches in each pair of arc-shaped branches The support bars are arranged facing each other, and the arc-shaped support bars are embedded in the side wall of the plastic sheet layer; the metal bottom plate is located on the periphery of the positioning cylinder and has several strip-shaped through holes at intervals along the circumferential direction, adjacent to the strip-shaped through-holes There is a reinforcing rib between them, and the surface of the plastic plate layer facing the impeller is provided with several outwardly protruding protrusions at intervals. The heat dissipation fan of the present invention not only reduces the overall weight of the axial fan, but also reduces the noise generated when the gas enters the impeller from the air inlet along the axial direction and then is discharged from the impeller along the radial direction under the pressure difference, thereby bringing comfort to the user .

Description

technical field [0001] The invention relates to a heat dissipation fan for a notebook computer, belonging to the field of heat dissipation of electronic products. Background technique [0002] As people pay more and more attention to the quality of life and taste, the pursuit of technology is becoming more and more perfect. Portable and trendy electronic devices such as notebook computers are also tending to be thinner and more refined. The cooling fan is a very important cooling module for computer products (especially notebook computers), because the temperature will directly affect the operating performance, stability and service life of the CPU, and the structural design of the cooling fan is also relatively with the computer The design development trend of product form changes. However, the noise of the fan used in the existing electronic products is relatively high, which affects the comfort of users of the electronic products. Contents of the invention [0003] Th...
