Description

Technical Field

[0001] The present invention relates to the technical field of computers, and in particular to a notebook computer. Background Art

[0002] With the continuous development of electronic technology, notebook computers have been loved by people due to their small size and portability, and have been widely used in people's daily lives.

[0003] Laptop computers are made up of the same hardware as traditional desktop computers, including a monitor, keyboard / mouse, CPU, memory, and hard disk. However, with the same components, laptop computers are small, light, and easy to carry. Generally speaking, portability is the biggest advantage of laptops over desktop computers. A typical laptop weighs only about 2 kilograms, so it is very convenient to carry it with you whether you are working or traveling.

[0004] With the development of technology, the working speed of each electronic component in the laptop computer is increasing, and the heat generated by it is also increasing accordingly. In order to enable the electronic components to operate at high speed, the heat generated by them needs to be discharged as soon as possible, otherwise the electronic components cannot work normally or even be burned by high temperature. Therefore, a heat dissipation module needs to be installed in the laptop computer to accelerate the heat dissipation of the electronic components and ensure the normal operation of the electronic components.

[0005] In existing laptop computers, the heat dissipation module generally includes a fan with an air outlet, a heat dissipation fin group provided at the air outlet of the fan, and a heat pipe connecting the heat dissipation fin group and the heat generating electronic component. The heat dissipation module transfers the heat generated by the heat generating electronic component to the heat dissipation fin group through the heat pipe and uses the airflow generated by the operation of the fan to dissipate the heat at the heat dissipation fin group to the surrounding air, which meets the heat dissipation requirements of the laptop computer to a certain extent. However, for laptop computers with a large heat output, the heat around the heat generating device makes the air temperature inside the casing very high, and the heat cannot be taken away by the heat pipe alone, resulting in a slightly insufficient heat dissipation performance, so that the heat dissipation effect of the laptop computer needs to be improved.

[0006] At the same time, in order to ensure the heat dissipation effect in the above-mentioned heat dissipation module, the air outlet of the fan must be arranged as close to the heat dissipation fin group as possible, that is, the fan and the heat dissipation fin group are inseparable and must be placed in the same area as a whole, and cannot be divided into two parts and arranged separately, which will cause the heat dissipation module to occupy a larger whole piece of fabric space when arranged. In the current situation where the fabric space of laptop computers is becoming increasingly tight and the size of laptop computers is becoming thinner and thinner, the heat dissipation module of this structure is becoming increasingly difficult to arrange, and the utilization rate of the fabric space inside the laptop computer cannot be improved. Summary of the invention

[0007] The purpose of the present invention is to provide a laptop computer, which can improve the heat dissipation performance of the laptop computer, while reducing the layout space occupied by the heat dissipation module, improving the layout flexibility of the heat dissipation module, and realizing a lighter, thinner and more portable laptop computer.

[0008] To achieve the above object, the present invention provides a laptop computer, comprising: a housing, a heating element and a heat dissipation assembly;

[0017] The other end of the first air duct is connected to the second air inlet, the other end of the second air duct is connected to the fourth air inlet, and the second air outlet is directly opposite to the first air outlet;

[0018] The cooperation between the air guide duct and the air guide slit enables the wind blown out from the wind source to be accelerated before entering the third air inlet.

[0034] To further illustrate the technical means and effects of the present invention, the following is a detailed description in conjunction with the preferred embodiments of the present invention and the accompanying drawings.

[0035] See also Figures 1 to 4 , the present invention provides a laptop computer, comprising: a housing 1, a heating element 2 and a heat dissipation component 3;

[0036] The heating element 2 and the heat dissipation assembly 3 are both disposed in the housing 1, and the outer surface of the housing 1 is provided with a first air inlet 11 and a first air outlet 12 spaced apart from each other;

[0037] The heat dissipation assembly 3 includes: an air source 31, a first air guide 32, an air guide head 33 and a second air guide 34;

[0038] The wind source 31 is disposed at the first air inlet 11;

[0039] One end of the first air guide pipe 32 is connected to the air source 31, and the other end is connected to the air guide head 33;

[0040] The air guide head 33 is disposed at the first air outlet 12;

[0041] One end of the second air guide pipe 34 is connected to the air guide head 33 , and the other end extends to the peripheral area of ​​the heating element 2 .

[0042] It should be noted that the heat dissipation module 3 in the laptop computer of the present invention utilizes the first air duct 32 and the air guide head 33 to conduct wind from the wind source 31 to the first air outlet 12, so that the wind source 31 does not need to be arranged close to the first air outlet 12, but can be arranged in any area in the shell 1 as needed, and then the heat emitted by the heating element 2 is drawn into the air guide head 33 through the second air duct 34 and blown out from the first air outlet 12, thereby realizing effective heat dissipation of the heating element 2, and the heating element 2 does not need to be arranged close to the wind source 31. That is, in the laptop computer of the present invention, the wind source 31 of the heat dissipation module 3 can be arranged at any position as needed without being restricted by the positions of the first air outlet 12 and the heating element 2, which can effectively improve the layout flexibility of the heat dissipation module 3.

[0043] In the meantime, please see Figures 2 to 4In order to improve the heat dissipation effect of the heat dissipation module, the present invention adopts a specially designed air guide head 33, which includes: a shell 331, a second air outlet 332 provided on a first side wall of the shell 331, a second air inlet 333 provided on a top wall of the shell 331, a third air inlet 334 provided in the shell 331 and spaced parallel to the second air outlet 332, an inner shell 335 connecting the third air inlet 334 and the second air outlet 332, and a fourth air inlet 336 provided on a second side wall of the shell 331, wherein the first side wall is opposite to the second side wall;

[0044] An air guide slit 337 is formed between the second side wall and the third air inlet 334 , and the air guide slit 337 is connected to the second air inlet 333 through an air guide duct 338 located between the outer shell 331 and the inner shell 335 ;

[0045] The other end of the first air duct 32 is connected to the second air inlet 333 , the other end of the second air duct 34 is connected to the fourth air inlet 336 , and the second air outlet 332 is directly opposite to the first air outlet 12 ;

[0046] The cooperation between the air guide duct and the air guide slit enables the wind blown out from the wind source to be accelerated before entering the third air inlet.

[0047] During operation, the wind source 31 directly draws outside cold air from the first air inlet 11 and blows it to the first air duct 32, and then blows it from the first air duct 32 to the second air inlet 333, and then blows it into the third air inlet 334 at high speed after passing through the air duct 37 and the air guide slit 36, and then passes through the inner shell 335, blows it from the second air outlet 332 to the first air outlet 12, and finally blows it out from the first air outlet 12. Since the airflow in the air guide head 33 flows to the first air outlet 12 at a high speed, according to the fluid mechanics principle that the faster the flow rate, the smaller the fluid pressure, a pressure drop will be generated in the air guide head 33. The negative pressure forces the air flow in the second air duct 34 connected to the fourth air inlet 336 of the air guide head 33 to flow toward the air guide head 33, so that the hot air in the peripheral area of ​​the heating element 2 located at the other end of the second air duct 34 is drawn to the second air duct 34, and then enters the air guide head 33 through the fourth air inlet 336, and is blown out from the first air outlet 12 through the air guide head 33, so that the heat in the peripheral area of ​​the heating element 2 is quickly dissipated through the first air outlet 12, thereby achieving effective heat dissipation of the heating element 2 and ensuring the normal operation of the heating element 2.

[0048] Specifically, the housing 1 includes a bottom shell 101 and a surface shell 102 rotatably connected to the bottom shell 101 , and the heating element 2 and the heat dissipation assembly 3 are both disposed in the bottom shell 101 .

[0049] Specifically, the first air inlet 11 is disposed on the bottom surface of the bottom shell 101 .

[0050] Preferably, the first air inlet 11 includes a plurality of air inlet holes 111 arranged in an array.

[0051] Of course, this is not a limitation of the present invention, and the first air inlet 11 may also be located on other surfaces of the bottom shell 101, such as the side, and the shape of the first air inlet 11 may also be optimized as needed, which will not affect the implementation of the present invention.

[0052] Specifically, the first air outlet 12 is disposed on a side surface of the bottom shell 101 .

[0053] Preferably, the first air outlet 12 includes a plurality of air outlet slits 121 arranged in parallel and at intervals.

[0054] Of course, this is not a limitation of the present invention, and the first air outlet 12 may also be located on other surfaces of the bottom shell 101, such as the bottom surface, and the shape of the first air outlet 12 may also be optimized as needed, which will not affect the implementation of the present invention.

[0055] Preferably, the wind source 31 is an air pump. By using an air pump instead of a fan with blades as the wind source 31, the volume of the wind source can be reduced, and the flexibility of the layout of the heat dissipation module can be further improved.

[0056] Of course, this is not a limitation of the present invention. If necessary, the present invention may also select a fan as the wind source 31, which will not affect the implementation of the present invention.

[0057] Specifically, the heating element 2 is a processor, but this is not a limitation of the present invention. The heating element 2 can also be other components in a laptop computer, such as a battery or a graphics card or other high-power heating devices. In addition, it should be noted that the heating element 2 is generally installed on a motherboard (not shown), and then installed on the bottom case 101 through the motherboard, rather than directly installed on the bottom case 101.

[0058] In summary, the present invention provides a laptop computer, comprising: a shell, a heating element and a heat dissipation assembly; the heating element and the heat dissipation assembly are both arranged in the shell, and the outer surface of the shell is provided with a first air inlet and a first air outlet spaced apart from each other; the heat dissipation assembly comprises: a wind source, a first air duct, an air guide head and a second air duct; the wind source is arranged at the first air inlet; one end of the first air duct is connected to the wind source, and the other end is connected to the air guide head; the air guide head is arranged at the first air outlet; one end of the second air duct is connected to the air guide head, and the other end extends to the peripheral area of ​​the heating element.
