Description

Technical Field

[0001] The utility model relates to the technical field of notebook computers, in particular to a notebook computer heat dissipation system. Background Art

[0002] In current laptop cooling systems, the motherboard in the laptop base is cooled by two cooling fans. A through-hole is provided at the bottom of the motherboard, which draws air into the base. Two cooling fans are spaced apart on the left and right sides of the bottom of the motherboard, and the air inlets of both fans are located on the bottom sides of the fans. The air inlets draw in air entering the base through the through-hole, while the air outlets of both fans face the cooling holes on the left and right sides of the rear wall of the base, blowing air directly into the cooling holes through the air outlets.

[0003] In the current notebook cooling system, the two cooling fans act independently and cannot be linked together, resulting in no air flow in the base, which leads to poor cooling effect of the cooling fans on the motherboard. Utility Model Content

[0020] The present invention will now be further described with reference to the accompanying drawings and specific implementation methods.

[0021] like Figures 1 to 5 As shown, a notebook 1 cooling system includes a base 10, a bottom wall of the base 10 is provided with a first through hole 11, the first through hole 11 makes the base 10 communicate with the inside and outside, the side wall of the base 10 is provided with a heat dissipation hole 13, the heat dissipation hole 13 is used to guide air, the base 10 has a horizontally arranged motherboard 14, the bottom side of the motherboard 14 is provided with a first cooling fan 15 and a second cooling fan 16 for cooling the motherboard 14, the first cooling fan 15 has a first air inlet 151 and a first air outlet 152, the first air inlet 151 faces the first through hole 11, and the first air outlet 152 faces Toward the second cooling fan 16, so that the first air outlet 152 blows air toward the second cooling fan 16, the second cooling fan 16 has a second air inlet 161 and a second air outlet 162, the second air inlet 161 faces the first through hole 11, and there is a gap between the second air inlet 161 and the bottom wall of the base 10, so that the air outside the base 10 and the air blown in by the first air outlet 152 are sucked in together through the second air inlet 161, and the second air outlet 162 faces the heat dissipation hole 13, so that the air blown out of the second air outlet 162 can be guided out of the base 10 through the heat dissipation hole 13.

[0022] Specifically, the air outside the base 10 is air with a lower temperature, and the air blown out of the first air outlet 152 and the second air outlet 162 is air with a higher temperature;

[0023] When the present invention is in use, the first air inlet 151 of the first cooling fan 15 draws in air from outside the base 10 through the first through hole 11, and blows the air to the second cooling fan 16 on the right side through the first air outlet 152. The air flow takes away the heat emitted by the mainboard 14. The second air inlet 161 of the second cooling fan 16 not only draws in air from outside the base 10 through the first through hole 11, but also draws in air blown from the first air outlet 152. Then, the air is blown toward the heat dissipation holes 13 through the second air outlet 162, and the air is discharged to the outside of the base 10 through the heat dissipation holes 13. In this way, the first cooling fan 15 and the second cooling fan 16 are linked and no longer act separately, and the air in the base 10 is caused to flow, thereby dissipating the heat of the mainboard 14 and other parts between the first cooling fan 15 and the second cooling fan 16, so that the heat dissipation effect of the mainboard 14 is better and the heat dissipation efficiency is higher.

[0024] Furthermore, it also includes a second through hole 12, which is arranged on the left side of the rear wall of the base 10, and the heat dissipation hole 13 is located on the right side of the rear wall of the base 10. The first through hole 11 and the second through hole 12 jointly intake air into the base 10 to increase the efficiency of intake air into the base 10.

[0025] Specifically, there are multiple first through holes 11, and the multiple first through holes 11 are arranged from the left side of the bottom wall of the base 10 to the right side of the bottom wall of the base 10 to increase the air intake efficiency of the base 10. There are also multiple second through holes 12, and the multiple second through holes 12 are arranged from the middle of the rear wall of the base 10 to the left end of the rear wall of the base 10 to further increase the air intake efficiency of the base 10. There are also multiple heat dissipation holes 13, and the multiple heat dissipation holes 13 are arranged from the middle of the rear wall of the base 10 to the right end of the rear wall of the base 10 to increase the efficiency of the heat dissipation holes 13 in extracting air.

[0026] Specifically, the first air inlet 151 is located at the bottom of the first cooling fan 15, and the second air inlet 161 is located at the bottom of the second cooling fan 16. Specifically, the first cooling fan 15 and the second cooling fan 16 are both located above the first through hole 11 to facilitate the first air inlet 151 and the second air inlet 161 to take in air.

[0027] Preferably, the first cooling fan 15 is located on the front side of the second through hole 12, and the second cooling fan 16 is located on the front side of the heat dissipation hole 13, so as to reduce the distance between the first air inlet 151 and the second through hole 12, and reduce the distance from the second air outlet 162 to the heat dissipation hole 13, thereby increasing the efficiency of the first air inlet 151 in sucking air from the second through hole 12, and increasing the efficiency of the second air outlet 162 in blowing air to the outside of the base 10 through the heat dissipation hole 13.

[0028] The directional terms mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. Any equivalent changes made based on the key design of this case shall fall within the scope of protection of this case.
