Taking a notebook computer as an example, for users who need to be on the go, the miniaturization of the notebook computer greatly improves the convenience in use. However, the heat generation per unit area of electronic components in notebook computers has also been increased due to the reduction in volume. If the internal heat of the notebook computer cannot be exhausted effectively, the internal high temperature will affect the stability and efficiency of the electronic components during operation, and even shorten the life of the notebook computer. In order to solve the problem of high temperature of the electronic components in the notebook computer during operation, the entire liquid-cooled heat sink is generally assembled in the mainframe of the notebook computer with a keyboard, so as to reduce the electronic components in the mainframe. temperature.

Due to the thin body, it is difficult to expand the distribution range of the heat dissipation holes located in the main frame. In detail, the ventilation holes are set to exhaust the air flow generated by the cooling fan in the liquid-cooled heat dissipation module, and the ventilation holes are generally located on the side away from the user to prevent the hot air from the ventilation holes from blowing to the user. The surface away from the user has a small area due to the thin and light design. Therefore, if the entire liquid-cooled heat dissipation module is arranged in the mainframe, the area of the heat dissipation hole will be limited. Because the distribution range of the cooling holes is positively related to the cooling efficiency of the liquid-cooled cooling system, the cooling holes with a limited distribution range also reduce the cooling efficiency of the liquid-cooled cooling system.

The present invention is to provide a portable electronic device, by moving a cooling fan and a cooling bar from the mainframe to the display body, and arranging a wide range of heat dissipation holes on the surface of the display body away from the user to solve the problem of setting the whole The liquid-cooled heat dissipation system squeezes other electronic components in the light and thin host base, and the distribution range of the heat dissipation holes is limited, which reduces the heat dissipation performance of the liquid-cooled heat dissipation module.

The portable electronic device disclosed in one embodiment of the present invention includes a host base, a display body, and a liquid-cooled heat dissipation module. The display body is pivotally connected to the main body base, so that the display body can be opened or closed relative to the main body base. The liquid-cooled heat sink module includes a heat sink, a heat sink fan, a liquid-cooled head, and a flexible flow tube. The heat dissipation bar and the cooling fan are arranged on the display body, the liquid cooling head is arranged on the host body, and a flexible flow tube is used to connect the liquid cooling head and the heat dissipation bar.

According to the portable electronic device disclosed in the above embodiment, the liquid-cooled heat-dissipating module and the heat-dissipating fan are moved from the host base to the display body, so that the liquid-cooled heat-dissipating module is located in the host base. The occupied space is reduced, and the ventilation holes provided on the surface far from the user have a larger distribution range. In this way, in addition to improving the configuration space and flexibility of the electronic components in the host base, Larger range of ventilation holes increase the amount of air in and air out to improve the heat dissipation efficiency of the liquid-cooled cooling module.

The support base 500 is movably disposed on the display body 200, so that the support base 500 has a support position (as shown in FIG. 4) and a storage position (as shown in FIG. 3). When the portable electronic device 10 is opened, and When the support base 500 is located at the support position (as shown in FIG. 4), the support base 500 protrudes from the side of the heat dissipation base 201 away from the host base body 100, and the support base 500 is used to support the portable electronic device 10 to improve the usability. Stability of the portable electronic device 10 when placed. When the support base 500 is located in the storage position (as shown in FIG. 3), the support base 500 is stored in the heat sink 201. In other embodiments, the portable electronic device does not need to be provided with a support base.

Specifically, when the display body 200 is opened relative to the host base 100, the display body 200 has a closed mode and a fully expanded mode. When the display body 200 is in the closed mode, the display base 202 covers the first heat dissipation hole 2012 and the wind shield 203. It is accommodated in the groove 2013 to shield the second heat dissipation hole 2014, and the support base 500 is located in the storage position (as shown in FIG. 3). When the user switches the portable electronic device 10 to the fully expanded mode, the display base 202 moves to reveal the first heat dissipation hole 2012, while the wind shield 203 moves to reveal the second heat dissipation hole 2014, and the support base 500 is in the storage position ( (As shown in Figure 3) to the support position (as shown in Figure 4). The display base 202, the windshield 203, and the support base 500 are moved, for example, by driving the display base 202 with a driving element, and simultaneously interlocking with the linkage components connected to the driving element, the display base 202, the windshield 203, and the support base 500.
