Radiator fan and electronic device adopting same

Abstract

The invention relates to an electronic device comprising a bottom plate and a cover plate corresponding to the bottom plate, the bottom plate is mutually combined with the cover plate to form an accommodating space, and a fan is arranged in the accommodating space; the fan comprises an impeller and a bracket, wherein the frame is arranged on the bottom plate, the impeller is rotatably arranged on the bracket and comprises a hub and a plurality of blades annularly arranged on the hub, and the tail end of each blade directly corresponds to the bottom plate. The electronic device at least can increase the arrangement space of the tail end of the blade in a height direction and increase the sweeping capability of the fan, thereby improving the radiating performance.

Description

technical field [0001] The present invention relates to a cooling fan, in particular to a cooling fan suitable for portable electronic devices such as notebook computers. Background technique [0002] At present, with the progress of science and technology and the demand of market development, high-performance and ultra-thin electronic products such as notebook computers have become the goals pursued by people. With the improvement of the multi-functional requirements of this product, the heat generated by the heating electronic components in this product is also increasing. In order to effectively dissipate these excess heat, the existing method is to attach a A radiator, and then a fan is arranged on the radiator, and the cooling airflow generated by the fan is used to forcibly dissipate heat from the radiator, thereby dissipating the heat generated by the heating electronic components. [0003] Existing notebook computers generally include a base plate and a cover plate ...

AI Technical Summary

Problems solved by technology

[0003] Existing notebook computers generally include a base plate and a cover plate corresponding to the base plate. The base plate and the cover plate are combined to form a closed storage space, and a fan is accommodated in the storage space. The fan generally includes a fan frame and An impeller arranged in the fan frame, the fan frame includes a lower plate, a side wall formed by extending upward from the lower plate and an upper plate covered on the side wall, each of the upper plate and the lower plate is provided with an air inlet, the After the fan is assembled on the electronic device, there is a certain distance between the upper and lower air inlets of the fan and the cover and bottom plate of the notebook computer to ensure the air intake of the fan. However, with the development trend of thinner and lighter notebook computers, When the height of the system is limited, the distance between the upper and lower air inlets of the fan and the cover and bottom plate of the notebook computer will be compressed and reduced, and the flow rate of the fan will also be greatly reduced
