Description

Technical Field

[0001] The utility model relates to the technical field of notebook heat dissipation, in particular to an air outlet structure used for notebook computer heat dissipation. Background Art

[0002] The main function of the notebook computer's air outlet structure is to discharge the heat generated inside the notebook computer to the outside, thereby preventing the computer from overheating and maintaining the stability and performance of the hardware components. Specifically, the CPU, GPU and other components of the notebook computer will generate a lot of heat when working. If the heat cannot be discharged effectively, the computer may overheat, resulting in reduced performance, system instability, and even hardware damage. The air outlet structure is usually located on the side or rear of the notebook case. It is a key part of the notebook computer's cooling system, allowing hot air to flow out. The cooling fan will draw in cold air and pass through the heat sink, absorb the heat absorbed by the heat sink and heat pipe from the high-temperature components, and push the collected hot air to the air outlet, and finally discharge it outside the notebook.

[0003] Currently, most notebook cooling outlets directly discharge hot air to achieve the purpose of heat dissipation. This method is difficult to achieve good results when the notebook is working at high temperature for a long time. It may damage the computer's battery in the long run and reduce the computer's service life. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0030] To solve the problems in the background technology, such as Figures 1 to 3 As shown, the utility model proposes an air outlet 11 structure for heat dissipation of a laptop computer, comprising a laptop body 1 and a heat dissipation structure 2. The air outlet 11 is opened on a side wall of the laptop body 1 adjacent to a fan, the heat dissipation structure 2 is arranged adjacent to the air outlet 11, the heat dissipation structure 2 is snapped onto the wall edge of the laptop body 1, the heat dissipation structure 2 partially covers the air outlet 11, and the heat dissipation structure 2 extends along the wind outflow direction.

[0031] It can be understood that the heat dissipation structure 2 is an additional accessory responsible for guiding the hot air to flow in a specific direction to prevent the hot air from being discharged directly. The design of the heat dissipation structure 2 being connected to the wall edge of the notebook body 1 can be through fasteners, slide rails or other mechanical fixing methods to firmly fix it on the notebook body. The heat dissipation structure 2 covers part or all of the air outlet 11, which helps to control the direction and speed of the airflow. The heat dissipation structure 2 extends along the wind outflow direction to expand the flow range of the heat dissipation wind and reduce the wind pressure at the air outlet 11, thereby making the heat dissipation more uniform and efficient; this structure helps to optimize the air flow path and ensure that heat can be quickly extracted from the heat source of the computer, such as the CPU and GPU, by the fan and discharged to the outside of the notebook through the heat dissipation structure 2 for further utilization.

[0032] like Figures 1 to 3 As shown, in one embodiment of the present application, the heat dissipation structure 2 includes a guide plate 21 and a heat sink 22. The guide plate 21 is arranged facing the air outlet 11, and the guide plate 21 partially covers the air outlet 11. The heat sink 22 is attached to the wall of the notebook body 1. A plurality of heat sinks 22 are arranged at intervals, and the heat sink 22 is connected to the wall of the guide plate 21.

[0033] It can be understood that the guide plate 21 is located in front of the air outlet 11. The main function of the guide plate 21 is to guide the hot air discharged from the air outlet 11 so that it flows along a predetermined path. Its design can help optimize the airflow generated by the cooling fan, control the direction of the wind flow, and reduce the interference of hot air on the user, so as to improve the heat dissipation efficiency; the heat sink 22 is a thin sheet made of metal material such as aluminum or copper, which is tightly attached to the inner wall of the laptop computer to improve heat conduction. The heat sink 22 is arranged at multiple intervals to increase their surface area, helping the heat sink 22 to absorb more heat generated by the internal components of the notebook computer such as the CPU and GPU, and conduct the heat to the outside air. The heat sink 22 is connected to the wall of the guide plate 21, which means that they form an integrated heat dissipation unit. The guide plate 21 not only guides the airflow, but also participates in the heat conduction process, and further spreads the heat collected from the heat sink 22 to a wider area, thereby achieving heat discharge with the help of airflow.

[0034] like Figure 3As shown, in one embodiment of the present application, the guide plate 21 is provided with guide grooves 211 , and the guide grooves 211 are arranged at intervals on the side of the guide plate 21 facing the air outlet 11 .

[0035] It can be understood that the guide groove 211 can guide the hot air to flow along a specific path, which helps to form effective airflow dynamics, thereby keeping the hot air away from heat-sensitive components such as processors or graphics cards. When the air passes through the guide groove 211, turbulence will be generated, which can increase the contact efficiency between the air and the surface of the heat sink 22 and promote heat exchange; the guide grooves 211 arranged at intervals can more evenly distribute the hot air blown out from the fan, which can avoid the concentration of heat in a specific area and help improve the overall heat dissipation effect; the guide grooves 211 can also reduce the generation of airflow noise by dividing the airflow, which is very beneficial for improving the user experience of the laptop computer.

[0036] like Figure 3 As shown, in one embodiment of the present application, the inner wall surface of the guide plate 21 is set to be a curved surface.

[0037] It can be understood that the curved surface can guide the airflow more smoothly, reduce the direct impact of the airflow on the guide plate 21, and avoid additional turbulence and airflow separation, which can ensure that the airflow passes through the heat dissipation system with lower resistance and improve the fan efficiency. According to Bernoulli's principle, the airflow will slow down its diffusion when passing through the curved surface, thereby increasing the flow rate in the corresponding area, which helps to take away heat more quickly. The curved surface design helps to reduce the friction and turbulence between the airflow and the surface, thereby reducing the noise level generated during operation and providing users with a more comfortable use environment; compared with right-angle or sharp-angle designs, the curved surface provides less wind resistance, thereby reducing the power required by the fan, which can indirectly increase the overall energy efficiency.

[0038] Specifically, the arc-shaped design of the inner wall not only helps to guide the hot air flow to the air outlet 11, but also helps to diffuse the hot air flow, so that the heat can be dispersed in a wider area and discharged more effectively by the guide plate 21 and the heat sink 22 system.

[0039] like Figures 1 to 3 As shown, in one embodiment of the present application, the heat dissipation structure 2 further includes a refrigerator 23, and a portion of the refrigerator 23 is disposed through the wall surface of the guide plate 21 to cool the hot air.

[0040] It can be understood that the refrigerator 23 enables the device to not only rely on traditional air cooling, for example, through fans and heat sinks 22 to dissipate heat, but also adopts an additional cooling mechanism to further reduce heat. The gas compression refrigerator 23 uses a refrigerant cycle, which absorbs and releases heat through a compression and expansion process, thereby cooling the released heat, so that the hot air refluxed in the guide plate 21 is cooled, further enhancing the heat dissipation efficiency.

[0041] like Figures 1 to 3 As shown, in one embodiment of the present application, a snap-on assembly 3 is provided at the connection between the heat dissipation structure 2 and the notebook body 1 so that the heat dissipation structure 2 is snap-on connected to the notebook body 1 .

[0042] It can be understood that the design of the snap-on assembly 3 enables the heat dissipation structure 2 to be snapped onto the notebook body 1 simply by pressing or pushing, without the need for tools or excessive force; once the heat dissipation structure 2 is installed in place, the snap-on assembly 3 will ensure its stable fixation, reducing unnecessary movement or vibration. The heat dissipation system requires regular dust cleaning or replacement of components such as the heat sink 22 and fan. The snap-on assembly 3 can be used to quickly remove the heat dissipation structure 2 for cleaning or maintenance; traditional screw fixing systems may require tools such as screwdrivers for installation and removal, but the use of the snap-on assembly 3 eliminates this requirement, making it more convenient for users to operate at any time.

[0043] like Figures 2 to 3 As shown, in one embodiment of the present application, the snap-fit ​​assembly 3 includes a fixing seat 31 and a snap-fit ​​seat 32, the fixing seat 31 is connected to the heat sink 22, a spring 311 is embedded in the inner wall of the fixing seat 31; the snap-fit ​​seat 32 is fixed to the end of the spring 311, the snap-fit ​​seat 32 is provided with a fixing plate 321, and the fixing plate 321 is elastically connected to the end face of the snap-fit ​​seat 32.

[0044] It can be understood that the snap-on assembly 3 in the heat dissipation structure 2 is a two-component system, mainly composed of a fixing seat 31 and a snap-on seat 32, which together realize the quick connection and release of the heat dissipation structure 2 and the notebook computer body. The fixing seat 31 is a part of the extension of the connection heat sink 22, and can be attached to the heat dissipation structure 2 by welding, screws, or other means. The function of the fixing seat 31 is to provide a stable base point for installing the snap-on assembly 3, and provide the necessary elastic force to maintain the tightness and safety of the connection, while also allowing a certain degree of flexibility to adapt to loading and unloading operations; the snap-on seat 32 provides a mating part for the spring 311 on the fixing seat 31, one end of the snap-on seat 32 is fixed to the end of the spring 311, and is connected to the fixing seat 31 through the spring 311, and the fixing plate 321 on the snap-on seat 32 further enhances the connection between the components. This plate is elastically connected to the end face of the snap-on seat 32 through an elastic element, and its purpose is to provide stress when the snap-on assembly 3 is matched with the notebook body 1 to resist falling off due to vibration or movement, so that the disassembly process becomes simple.

[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
