A heat sink for a foldable notebook computer

Abstract

The invention relates to a foldable laptop radiator, which comprises a cooling bracket, a first cooling fan, a second cooling fan, a third cooling fan, a fourth cooling fan, a USB (Universal Serial Bus) plug and a switch button, wherein the first cooling fan, the second cooling fan, the third cooling fan and the fourth cooling fan are installed on the cooling bracket; the USB plug is imported out from the cooling bracket; and the switch button is arranged on one end of the cooling bracket. The foldable cooling bracket is utilized, side wing brackets are flexible and can be folded with lateral brackets at an angle of 90 degrees, the lateral brackets can be folded at an angle of 180 degrees, and therefore, the foldable laptop radiator is convenient in carrying. Fans on two sides are used for driving air to horizontally flow to enlarge an air flowing range, and the positions of the fans can be regulated to meet the cooling requirements of the laptops of different models.

Description

technical field [0001] The invention relates to a radiator for a computer, in particular to a radiator for a foldable notebook computer. Background technique [0002] At present, due to the popularity of notebook computers, various types of notebook computer radiators have appeared on the market. The existing radiator for notebook computer can be placed at the bottom of the notebook computer, and two or three cooling fans in the middle of the radiator can be used to dissipate heat from the bottom of the notebook computer. But the following two problems generally exist in existing notebook computer heat sink: [0003] 1. The cooling effect is not good. The cooling fan installed at the bottom of the notebook computer will generate vertical cooling airflow, but the narrow space in the vertical direction cannot fully circulate the heat discharged by the notebook computer, and the hot air will flow back to the bottom of the notebook computer from the desktop. Different models ...

AI Technical Summary

Problems solved by technology

[0003] 1. Poor cooling effect

The cooling fan installed at the bottom of the notebook computer will generate vertical cooling airflow, but the narrow space in the vertical direction cannot make the heat exhausted by the notebook computer circulate sufficiently, and the hot air will flow back from the desktop to the bottom of the notebook computer

Different models of laptops have different heating parts, and fixed-position cooling fans cannot meet the needs of all models of laptops to focus on heat dissipation in high-heat areas.

For example, Chinese patent CN204557368 discloses a radiator for notebook computers. The heat dissipation fan of the radiator is installed on the heat dissipation panel, and the folding function of the support is realized by two heat dissipation high and low support assemblies, but the heat dissipation surface is small and cannot effectively meet the needs. cooling area

Therefore, the heat dissipation effect of the existing notebook computer radiator is not good

[0004] 2. Not easy to carry

This method can adapt to the heat dissipation requirements of various brands of notebook computers and improve the heat dissipation effect, but because this heat sink does not have the folding function, it is not convenient to carry

Another example is a notebook computer radiator disclosed in Chinese invention patent CN103885560A. This radiator includes an air suction fan embedded in a cooling plate and an independent air suction fan. The heat dissipation port conducts active heat dissipation to improve the overall heat dissipation effect of the radiator, but it also does not have the folding function, which is inconvenient to carry

[0005] From the above analysis, it can be seen that the published designs of notebook computer heat sinks mainly focus on the improvement of heat dissipation function or folding function, but currently there is no heat sink in the industry that can improve heat dissipation performance and is easy to carry
