Mixed convection heat radiation type notebook computer heat radiator

Abstract

The invention discloses a mixed convection heat radiation type notebook computer heat radiator, which comprises front supporting legs, base plates, sealing pads, micro axial flow fans, flow guide sheets and rear supporting legs, and is characterized in that the front supporting legs and the rear supporting legs are respectively fixed on the base plates; the front supporting legs are higher than the rear supporting legs, so that the front part and the rear part of the notebook computer heat radiator have a height difference; each micro axial flow fan is arranged on one side of the back of each base plate, which is close to each rear supporting leg; the flow guide sheets are arranged on the tops of the base plates; the flow guide sheets, the base plates and the bottom of a notebook computer form a flow guide channel; and the sealing pads are arranged on the tops of the flow guide sheets. The mixed convection heat radiation type notebook computer heat radiator has the advantages of 1) simple and scientific structure, 2) high heat radiation uniformity and 3) low production cost.

Description

Technical field [0001] The invention relates to a heat sink, in particular to a hybrid convection heat dissipation type notebook computer heat sink. Background technique [0002] As the most commonly used office tool for people, notebook computers have greatly improved people's work efficiency and work quality. With the improvement of notebook computer performance, its heat generation is also increasing. When notebook computers run for a long time, heat accumulation is difficult to dissipate and it is easy Cause the computer to run slowly, or even cause the computer to freeze. Limited by the size of the notebook computer, it is impossible for the notebook computer itself to install a larger-sized heat dissipation component to increase heat dissipation. Therefore, an external notebook computer radiator is the main means to improve the heat dissipation performance of the notebook computer. Laptop radiators currently on the market have a variety of structures, but in terms of ...

Problems solved by technology

Laptop radiators currently on the market have a variety of structures, but in terms of heat dissipation methods, the combined effects of natural convection and forced convection have not been considered. Tests have shown that commercially available laptop radiators generally have the problem of poor heat dissipation uniformity. , that is, the place where the fan blows directly has good heat dissipation, and the place where the fan is difficult to blow has poor heat dissipation

Invention patent 201110273088.0 discloses a notebook computer radiator, which mainly includes a support frame and a base. One of the outlets is equipped with a micro-pump. This invention has good heat dissipation uniformity, but its structure is complex, inconvenient to use, and high energy consumption
