Description

TECHNICAL FIELD

[0001] The utility model relates to notebook computer casing field especially relates to a gradual change formula high -efficient heat dissipation notebook screen shell. BACKGROUND

[0002] The main role of notebook screen shell is to protect the screen from physical damage, and it is also an important part of notebook appearance design. It is usually made of plastic, metal or composite material, and the strength, weight, scratch resistance, beauty and heat dissipation performance should be considered in design. The design of screen shell also affects the screen opening mechanism, such as no lock design or traditional mechanical lock. In addition, the width of screen frame is also one of the design factors, and narrow frame design can reduce the overall size of notebook while keeping the screen size. If the notebook screen shell does not have heat dissipation effect, it may cause internal heat accumulation, which affects the performance of CPU and GPU and other key hardware. Overheating not only reduces the running speed of the device, but also may cause hardware to age or damage prematurely, shortening the service life of the notebook. In addition, long-term work in high temperature environment may also cause safety problems, such as battery overheating expansion and even fire.

[0003] However, the existing screen shell often encounters the following problems in use:

[0004] (1) The traditional screen shell will produce a certain amount of heat after long-term use, and the heat cannot be effectively dissipated due to the lack of heat dissipation effect. Long-term work in high temperature environment may accelerate the aging of internal components connected with the screen, and even damage, shorten the service life of the device

[0005] (2) Dust often enters the joint of the two sides of the traditional screen shell, and it is only necessary to disassemble and clean when it is necessary to clean. INVENTION CONTENTS

[0006] The main purpose of the utility model is to provide a gradual change formula high -efficient heat dissipation notebook screen shell, which can effectively solve the problem of safety hidden trouble caused by the fact that the slot of the existing traditional electroplating tank is always open.

[0007] To achieve the above purpose, the technical scheme adopted by the utility model is:

[0008] A gradual change formula high -efficient heat dissipation notebook screen shell, comprising:

[0009] The main shell comprises a clamping frame and an encapsulation plate, and the four sides of the encapsulation plate are connected with the clamping frame.

[0010] The gradual change formula high -efficient heat dissipation notebook screen shell further comprises a gradual change formula trapezoidal groove, which is arranged in the inner wall of the encapsulation plate.

[0011] A heat dissipation fin is arranged on the inner wall of the packaging plate;

[0012] Two sets of heat dissipation air ducts are arranged on the two sides of the clamping frame;

[0013] A hinge port is arranged on the bottom of the main shell;

[0014] A heat-conducting silica gel is attached to the extension direction of one side of the hinge port.

[0015] The gradually-changing trapezoidal groove further comprises:

[0016] A top cover is arranged on the inner wall of the packaging plate, and the heat dissipation fin is arranged on the packaging plate;

[0017] A trapezoidal groove is arranged around the top cover.

[0018] Further comprising:

[0019] A screen plate is attached to one side of the heat dissipation fin;

[0020] A clamping port is arranged on the heat-conducting silica gel.

[0021] The heat dissipation fin is a graphene heat dissipation fin.

[0022] The trapezoidal groove extends around the top cover in sequence.

[0023] The heat dissipation air duct is a diagonal air duct.

[0024] Compared with the prior art, the utility model has the beneficial effects that:

[0025] (1) The high thermal conductivity of the graphene heat dissipation fin and the structural design of the gradually-changing trapezoidal groove significantly improve the heat conduction and dissipation efficiency, effectively preventing the performance decline or damage of the notebook screen caused by overheating.

[0026] (2) The design of the diagonal air duct not only effectively dissipates heat, but also blocks dust from directly entering the screen shell, and only needs to be cleaned regularly, greatly reducing the maintenance difficulty and prolonging the service life of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figures 1-4As shown, a gradient-type high-efficiency heat dissipation laptop screen casing includes: a main shell 1, a gradient trapezoidal groove 2, a heat sink 3, a heat dissipation duct 4, a hinge interface 5, and thermally conductive silicone 6. The main shell 1 includes a snap-fit ​​frame 11 and a packaging plate 12. The packaging plate 12 is connected to the snap-fit ​​frame 11 on all four sides. The gradient trapezoidal groove 2 is formed on the inner wall of the packaging plate 12. The connection structure between the snap-fit ​​frame 11 and the packaging plate 12 ensures the stability of the casing. Simultaneously, the combination of the gradient trapezoidal groove 2 on the inner wall of the packaging plate 12 and the heat sink 3 forms an efficient heat dissipation and conduction path. The heat sink 3 is disposed on the inner wall of the packaging plate 12. Two sets of heat dissipation ducts 4 are provided, located on both sides of the snap-fit ​​frame 11. The hinge interface 5 is located at the bottom of the main shell 1. The thermally conductive silicone 6 is attached to one side of the hinge interface 5 along its extension direction. Since some of the heat from the laptop screen comes from the CPU inside the keyboard housing when it is in use, and the CPU conducts heat through the hinge between the keyboard and the screen, it will increase the screen load. At this time, the thermal conductive silicone 6 is suitable for this connection point to absorb heat to a certain extent.

[0036] In this real-time example, the gradient trapezoidal slot 2 further includes: a top cover 21 disposed on the inner wall of the encapsulation plate 12, and heat sink 3 mounted on the encapsulation plate 12; a set of trapezoidal slots 22 are formed, and the set of trapezoidal slots 22 is arranged around the top cover 21. The trapezoidal slots 22 extend progressively outward from the top cover 21 as the center, increasing the heat dissipation surface area and accelerating heat dissipation through air convection. In particular, the slots are designed to be denser in the central area where heat is concentrated, effectively enhancing heat dissipation. The design of the gradient trapezoidal slot 2 optimizes airflow, helps to form a more effective heat dissipation airflow 4, and improves the overall heat dissipation effect.

[0037] One side of the screen panel 7 is attached to the heat sink 3, and the card interface 8 is located around the card frame 11. The heat sink 3 is a graphene heat sink 3. The high thermal conductivity of graphene can significantly accelerate the conduction of heat from the heat source to the shell, improving heat dissipation efficiency. The use of graphene reduces the weight of the traditional metal heat sink 3, while maintaining or improving the heat dissipation effect, keeping the laptop thin, light, and portable. The heat dissipation air duct 4 is an angled air duct. The angled air duct not only allows the hot air guided by the gradient trapezoidal groove 2 to be discharged along the angled air duct, but also prevents dust from entering the angled air duct from being blocked by the inner wall of the angled air duct and accumulating inside the angled air duct, preventing it from directly entering the screen shell. Afterwards, only the air duct needs to be cleaned, without having to disassemble the entire shell.

[0038] It should be noted that the gradient high-efficiency heat dissipation laptop screen casing designed in this utility model, when the computer screen begins to heat up during use, the heat is first transferred to the heat sink 3 attached to it. The graphite heat sink 3 is attached to the entire back of the screen, which helps to quickly conduct the heat generated by the motherboard and other components away. The conducted heat is dispersed and guided to the edge of the main casing 1 by the gradient trapezoidal groove 2, and then discharged by the heat dissipation duct 4. The gradient trapezoidal groove 2 uses the structure of the groove to increase the heat dissipation area, while promoting air circulation and improving heat dissipation efficiency.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
