Description

TECHNICAL FIELD

[0001] The utility model relates to CPU heat dissipation technical field, specifically related to a heat dissipation structure. BACKGROUND

[0002] With the rapid progress of computer technology, the performance of central processing unit (CPU) has achieved significant improvement, providing users with more powerful and efficient data processing capabilities. However, this leap in performance is often accompanied by a sharp increase in power consumption, which in turn poses unprecedented challenges to the CPU cooling system. In order to ensure the stability and reliability of the CPU under high-intensity computing tasks, the innovation of heat dissipation technology has become a key problem that needs to be solved in the engineering field.

[0003] The traditional CPU cooling scheme mainly relies on the main heat sink, which absorbs and dissipates the heat generated during CPU operation. However, with the continuous rise of CPU power consumption, a single main heat sink is already difficult to meet the growing cooling needs. To address this challenge, engineers have made many attempts and innovations, one of which is to add two small heat sinks on both sides of the main heat sink and connect them to the main heat sink through efficient heat pipe technology, forming a whole cooling system. This design significantly increases the heat dissipation area, effectively improving the cooling effect, and to some extent, alleviating the problem of CPU cooling.

[0004] Due to the shape and location of the two small heat sinks, which are similar to the two horns of a goat, this cooling system is aptly named "goat horn heat sink". The goat horn heat sink has solved the problem of CPU cooling to some extent, but its limitations cannot be ignored. Specifically, due to the addition of two small heat sinks, the cooling system occupies a lot of mainboard space, causing the connectors below the heat sink to be blocked, making it impossible to plug directly. This design flaw brings great inconvenience to users, especially when plugging these connectors, users have to remove the entire heat sink, which not only takes time and effort, but also requires reapplying thermal paste to ensure good heat conduction when reinstalling the heat sink. This complex and tedious operation process is undoubtedly a great challenge for non-professionals, greatly limiting the application range and user experience of the goat horn heat sink. UTILITY MODEL CONTENTS

[0005] In order to overcome the shortcomings of the prior art, the present application provides a heat dissipation structure, which aims to overcome the limitations of the existing goat horn heat sink, improve the cooling efficiency, reduce the occupation of the mainboard space, and simplify the installation and removal process of the heat sink, thereby providing users with a more convenient and efficient cooling solution.

[0009] The fixed support body is connected with the main radiator, and the first extension radiator and the second extension radiator are lifted through the movable support, and when the movable support is deformed, the first extension radiator and the second extension radiator are rotated.

[0010] The fixed support includes a support body, an upper support, a horn cradle, a left support and a right support.

[0025] The present application will be further described below in combination with the drawings and embodiments.

[0026] The concept, specific structure and generated technical effects of the present application will be clearly and completely described below in combination with the embodiments and drawings, so as to fully understand the purposes, features and effects of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application. In addition, all the coupling / connection relations involved in the patent do not mean that the components are directly connected, but means that a better coupling structure can be formed by adding or reducing coupling auxiliary components according to the specific implementation situation. The various technical features in the present application creation can be interactively combined without mutual contradiction and conflict.

[0027] As Figure 1 shown, the present application provides a heat dissipation structure, which comprises a main heat dissipator 1, a first extended heat dissipator 2, a second extended heat dissipator 3, a heat conduction pipe 4, a heat dissipation block 5, a heat dissipation fin 6 and a fixing support 7, wherein,

[0028] The heat pipe 4 is arranged at one end of the main heat sink 1, the bottom of the main heat sink 1 is in contact with the CPU, and the heat sink 5 is fixedly arranged above the heat pipe 4.

[0029] The first and second extension heat sinks 2 and 3 are connected to the heat sink 5 through the heat dissipation fins 6 respectively; the heat dissipation fins 6 are soft and can be bent by a certain angle.

[0030] The fixed support 7 is connected to the main heat sink 1, and the first and second extension heat sinks 2 and 3 are lifted by the movable support; when the movable support is deformed, the first and second extension heat sinks 2 and 3 are rotated.

[0031] In a possible implementation, as shown in the drawings, Figures 2-4 The fixed support 7 includes a support body 71, an upper support 72, a horn cradle 73, a left support 74, and a right support 75, wherein,

[0032] The side plate of the support body 71 is provided with a sliding groove 711 in a hollow manner, and a limiting protrusion is arranged on the side plate of the main heat sink 1 corresponding to the sliding groove 711;

[0033] The upper support 72 is fixedly connected to the support body 71, the upper support 72, the horn cradle 73, the left support 74, and the right support 75 are circularly connected through a rotating shaft 76, and the horn cradle 73 is fixedly connected to the heat sink 5 through the rotating shaft 76.

[0034] In a possible implementation, the outermost layer of the heat dissipation fin 6 is a thin copper sheet, and the inner layer is a plurality of flexible graphite sheets. The plurality of flexible thin graphite sheets are used to replace the heat pipe. Because the graphite sheet has a high thermal conductivity (5300 W / m.K), the heat on the chip can be effectively dissipated; at the same time, the thin graphite sheet is flexible, and even if it is extruded by an external force, within a certain range of movement, the internal structure will not be damaged, and the heat conduction will not be affected.

[0035] Through the above embodiment, when the support body moves upward, the upper support drives the left support and the right support to move upward, so that the horn cradle lifts the first and second extension heat sinks to rotate upward, thereby leaving operation space for connectors or other plug-ins, and greatly overcoming the limitations of the existing horn heat sink and optimizing the operation procedure.

[0036] In a possible implementation, the fixed support further includes an adjusting device, and the adjusting device allows a user to adjust the inclination angle of the first and second extension heat sinks according to actual needs.

[0037] Optionally, the adjusting device is a spiral spring or a gas pressure rod, which changes the inclination angle of the first and second extended heat sinks by adjusting the compression degree. The design of the adjusting device should ensure structural stability, easy operation, and adaptability to different installation environments and heat dissipation requirements. By adjusting the inclination angle, the user can optimize the heat dissipation effect and improve the adaptability and flexibility of the heat dissipation structure.

[0038] In one possible implementation, the goat horn bracket is provided with a limiting structure for fixing the first and second extended heat sinks.

[0039] With the limiting structure, the first and second extended heat sinks can maintain stable positions when following the rotation of the goat horn bracket and will not slide downward due to gravity or other external factors. This greatly enhances the stability and reliability of the entire heat dissipation structure, preventing the decline of heat dissipation performance caused by loose or misaligned components.

[0040] In one possible implementation, the material of the fixing bracket is a lightweight high-strength alloy material, such as aluminum alloy or magnesium alloy, to reduce the overall weight and improve the structural strength. At the same time, the materials of the heat dissipation blocks, heat dissipation fins, and extended heat sinks are preferably metals with high thermal conductivity, such as copper, aluminum, or copper-aluminum alloy, to maximize the heat dissipation performance.

[0041] The use of lightweight high-strength alloy materials significantly reduces the weight of the fixing bracket, making the entire heat dissipation structure more portable. This not only facilitates installation and movement, but also helps to reduce the overall load of the equipment and improve the portability and flexibility of the equipment. Despite the use of lightweight materials, the high-strength characteristics of the alloy ensure the stability and durability of the fixing bracket. It can withstand large external forces and pressures, preventing deformation or damage that affects heat dissipation performance.

[0042] The above is a specific description of the preferred implementation of the present application. However, the present application is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without deviating from the spirit of the present application. These equivalent modifications or substitutions are all included within the scope defined by the claims of the present application.
