Description

An external notebook computer auxiliary cooling device

technical field

The utility model relates to a cooling device for electronic components, in particular to an auxiliary cooling device for an external notebook computer.

Background technique

As the performance of notebook computers gets higher and higher, the chips inside the machine generate more and more heat, and the chips can reach very high temperatures in a very short period of time. While enjoying the comfort brought by high-performance notebooks, people are also faced with the problem of continuously and effectively solving the heat dissipation of notebook computers. Poor heat dissipation will lead to system performance degradation, seriously affect the stability and reliability of the system, and will also affect the service life of other components. At present, most of the heat dissipation methods used in notebook computers are heat pipes + heat sinks + fans. Strengthening the heat exchange between the heat sink and the air medium is the main means of external cooling methods for notebook computers, such as the common notebook fan cooling base. The fan heat dissipation base takes away the heat from the notebook panel from the bottom. This method reduces the temperature of the panel by strengthening the convection heat exchange between the panel and the surrounding air. The improvement of the heat exchange of the heat sink in the notebook inner shell is limited, and the heat inside the system cannot be absorbed. Take away quickly.
