ELECTRONIC DEVICE Russian patent published in 2023 - IPC G06F1/20 H05K7/20 

FIELD: heat production.

SUBSTANCE: cooling components of electronic devices. The electronic device (100) has a display end (20) and a system end (10), which contains a body (1) and a heat dissipation unit (2). The body (1) has an internal chamber (11) for installing a heat dissipation unit (2). The heat dissipation unit (2) comprises a body (21), a heat sink (22) and an axial fan (23). The heat sink (22) and the axial fan (23) are connected to the body (21), and the body (21) is connected to the inner chamber (11). An air outlet (121) is located on the body (1), and the air outlet direction through the air outlet (121) coincides with the thickness direction (H) of the system end (10). Since the axial fan (23) can push the air flow in the same direction as the fan shaft (23) runs, the axial fan (23) can easily push the air towards the air outlet (121), thereby improving the heat dissipation of the electronic device (100).

EFFECT: improving heat dissipation from the heat sink, as well as a reduction in the volume of the heat dissipation unit, which helps to reduce the weight and reduce the thickness of an electronic device, such as a laptop.
