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

According to the portable electronic device disclosed in the above embodiment, the liquid cooling type heat dissipation module and the heat dissipation fan are moved from the main body to the display body, so that the liquid cooling type heat dissipation module is disposed in the main body.

The liquid cooling head 303, the liquid storage tank 304, and the pump 305 are disposed in the main body 100. The liquid storage tank 304 and the pump 305 are connected to the liquid cooling head 303. The flexible flow tube 306 is used to connect the liquid cooling head 303 and the heat dissipation row 301, and the heat dissipation liquid flows through the flexible flow tube 206 to the liquid cooling head 303 and the heat dissipation row 301 to form a cooling cycle. The two processing wafers 400 are disposed in the main body 100.
