Heat dissipation device of portable computer

Abstract

The invention provides a heat dissipation device of a portable computer. The heat dissipation device comprises a heat dissipation plate, a computer bottom plate, a sealing plate, a fan plate, and a movable block, wherein the heat dissipation plate is movably arranged outside the bottom plate of a computer; the computer bottom plate is internally provided with a movable cavity used for installing the sealing plate and the fan plate; the bottom end of the sealing plate is connected with a fan plate, and the sealing plate and the fan plate can move in a staggered mode; the fan plate is provided with a through hole for mounting a fan; and the movable block is arranged outside the computer bottom plate. According to the heat dissipation device of a portable computer, the movable heat dissipation mechanism is mounted on the bottom plate of the portable computer, and the fan on the opened heat dissipation plate is matched with the motor in the computer, and the motor starts to work after being powered on, and heat in the computer is discharged in an accelerated mode through the bottom plate opening, and the heat dissipation space of the computer can be enlarged through the mode, and the interior of the computer is directly communicated with external air.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a cooling device for a portable computer. Background technique [0002] As the name suggests, a portable computer is a computer that is easy to carry. Portability means the optimization of volume and weight. The optimization of volume will inevitably bring about the problem of heat dissipation. It often happens that the portable computer runs for a long time and causes the system to freeze or even shut down. The computer should not only make the structure of the components compact, but also leave enough space to make it have a space for heat dissipation. [0003] At present, portable computers dissipate the internal heat of the computer to the outside by installing ventilation holes on the side or bottom. The diameter of the heat dissipation holes is small, and it also prevents external dust from entering the computer, thereby affecting the operation of internal components. Th...

Problems solved by technology

[0003] At present, portable computers dissipate the internal heat of the computer to the outside by installing ventilation holes on the side or bottom. The diameter of the heat dissipation holes is small, and it also prevents external dust from entering the computer, thereby affecting the operation of internal components. The heat dissipated in this way is limited, especially after the computer has been used for a long time, a large amount of hot air will accumulate inside, and the hot air will form convection, resulting in part of the heat that cannot be dissipated at all, and can only be conducted through the computer case to facilitate the use of the computer , only plastic materials with low thermal conductivity can be used, which further limits the heat output; another way is to support a heat sink at the bottom of the portable computer, and a fan is installed on the heat sink to accelerate the heat dissipation of the computer base plate. The air flow of the computer accelerates the heat dissipation of the computer, thereby reducing the heat. This method cannot effectively accelerate the output of the internal heat of the computer. limited, it can only be better than the computer's natural cooling effect
