[0002] With the development of technology, the CPU's computing speed is getting faster and faster, and the heat generated is getting bigger and bigger. However, the stable operating temperature range of the CPU is limited. If the large amount of heat generated cannot be removed in time, it is easy to cause the CPU to exceed the operating temperature range, unstable operation or even damage. Therefore, it is very important to configure an efficient radiator and cooling fan for the CPU.

[0003] Traditional CPU radiators and cooling fans are often fixedly installed, with the radiator fixed to the CPU by screws and the cooling fan fixed to the radiator by fasteners. This connection method has fixed positions for the radiator and cooling fan, and can only be directed to the area directly above the CPU chip for air cooling. The airflow channel is single, which affects the cooling effect, and the fixed installation is inconvenient for disassembly, assembly, and maintenance.

[0004] In order to adjust the position of the radiator and the cooling fan and facilitate disassembly and assembly, magnetic adsorption or snap spring extrusion methods are also used. However, these connection methods are not accurately positioned, are easy to loosen, and cannot reliably ensure the position relationship between the radiator and the cooling fan. In addition, most radiators in the prior art use aluminum heat sinks, which have poor thermal conductivity and limited heat dissipation area, resulting in poor heat dissipation effect. Therefore, there is an urgent need for a new type of radiator and cooling fan connection structure that can adjust the position of the radiator and the cooling fan, thereby optimizing their alignment position and improving the heat dissipation effect. Utility Model Content

DETAILED DESCRIPTION

[0022] In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0023] In the present invention, unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixedly connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0025] The CPU computing speed is increasing day by day, and its power consumption and heat generation are also rising. However, the stable operating temperature range allowed by the CPU chip itself is limited. Once the cooling system fails to remove a large amount of accumulated heat in time, the CPU temperature is likely to soar to an unstable or even damaged point. Therefore, it is imperative to match an efficient cooling module and cooling fan for the stable operation of the CPU. However, traditional CPU cooling fans are mostly fixedly installed, and the resulting single air duct seriously affects the cooling effect and is inconvenient to disassemble and maintain. Therefore, there is an urgent need for a new connection structure that can realize the flexible adjustment of the position of the radiator and the cooling fan to optimize the spatial position of the two, thereby improving the cooling effect.

[0026] The utility model discloses a sliding device for connecting a radiator and a cooling fan, which realizes flexible sliding cooperation between the two through a sliding groove and sliding rod system. The sliding mode is not only convenient for adjusting the position of the cooling fan relative to the radiator, but also can select the cooling fan working position corresponding to different radiator parts according to needs, thereby optimizing the spatial position and improving the cooling effect. The structure is also provided with a gear adjustment system for fixing different working positions to meet different cooling requirements and ensure that the cooling fan is always aligned with the radiator. The sliding device is easy to manufacture, and is convenient and efficient to assemble and disassemble. It is very suitable for mass production and can effectively reduce costs.

[0027] The present invention will be further described and illustrated below in conjunction with specific embodiments and drawings.

[0028] Embodiment 1

[0029] The present embodiment provides a radiator with a sliding structure, the radiator includes a cooling fin group 1, a cooling fan 2 and a sliding structure 3 therebetween. In the present embodiment, the radiator includes at least one cooling fin group 1, the number and arrangement of which can be set according to actual needs. And at least one cooling fan 2, the cooling fan 2 is arranged on one side of the cooling fin group 1, that is, connected to the cooling fin group 1 through the sliding structure 3. The cooling fan 2 is mainly in the existing common form, including a cooling fan housing 23, and the cooling fan motor, impeller and other components can be arranged in the cooling fan housing 23. A slide 31 is arranged on the cooling fan housing 23, and the form of the slide 31 can be designed according to needs, such as a straight slide, an arc slide, etc., and a slide rod 32 that is movably adapted to the slide 31 is fixedly arranged on the cooling fin group 1. A gear adjustment device 33 is also provided between the slide slot 31 and the slide bar 32. The gear adjustment device 33 includes a positioning protrusion 331 fixedly provided on the slide bar 32 and a plurality of concave points 332 provided on the slide slot 31 and adapted to the shape of the positioning protrusion 331. An elastic member, such as a spring, is provided inside the positioning protrusion 331. When the slide bar 32 is inserted into the slide slot 31, the positioning protrusion 331 will be pushed into the corresponding concave point 332. Due to the elastic force of the spring, the slide bar 32 can be stably maintained at a certain position in the slide slot 31. By changing the position of the slide bar 32 in the slide slot 31, the distance between the heat dissipation fin group 1 and the heat dissipation fan 2 can be adjusted, thereby achieving the purpose of adjusting the heat dissipation effect.

[0030] In actual application, the user can slide the slide bar 32 to different positions of the slide slot 31 according to the heat dissipation requirements. By adjusting the compression amount of the spring, the pressure of the positioning protrusion 331 on the concave point 332 can be adjusted to fix the position of the slide bar 32 in the slide slot 31. This design allows the radiator to quickly and conveniently adjust the relative position with the cooling fan 2 to optimize the heat dissipation effect.

[0031] In this embodiment, the radiator is also provided with other internal structures to improve the heat dissipation effect, including a heat pipe 5, a base 4, and a copper bar or a heat spreader disposed below the base 4. The heat pipe 5 is clamped between the base 4 and the copper bar or the heat spreader, and both ends of the heat pipe 5 are U-shaped and penetrated in the heat dissipation fin group 1. The heat pipe 5 arranged in a U-shaped distribution plays a role in rapid heat transfer; the base 4 matched with the heat pipe 5 is fixedly connected to the copper bar or the heat spreader below the base 4; the heat pipe 5 is clamped between the base 4 and the heat spreader. Through this structure, the heat generated by the CPU can be quickly concentrated and conducted to the heat dissipation fins, thereby increasing the heat dissipation efficiency.

[0032] Embodiment 2

[0033] This embodiment adds a group of heat dissipation fins 1 and a heat dissipation fan 2 on the basis of the first embodiment. The radiator includes a first heat dissipation fin group 11, a second heat dissipation fin group 12, and a first heat dissipation fan 21 and a second heat dissipation fan 22 arranged on one side of the first heat dissipation fin group 11 and the second heat dissipation fin group 12.

[0034] The first heat sink fin group 11 and the second heat sink fin group 12 are both made of aluminum alloy material and have good thermal conductivity. The first heat sink fan 21 and the second heat sink fan 22 are DC motor fans of the same shape with a diameter of 10-20 cm and a rotation speed of 2000 rpm, which can provide sufficient air volume to take away the heat generated by the CPU. The two ends of the heat pipe 5 are bent and extend upward to the first heat sink fin group 11 and the second heat sink fin group 12. The stamping technology is used to form an oblate through hole on the first heat sink fin group 11 and the second heat sink fin group 12 to assemble and accommodate the heat pipe. The heat dissipation end of the heat pipe is stamped into an oblate shape corresponding to the oblate through hole, and is in close contact with the first heat sink fin group 11 and the second heat sink fin group 12 to ensure that the heat can be quickly transferred to the fins.

[0035] Embodiment 3

[0036] The difference between this embodiment and the second embodiment is that the first heat sink fin group 11 and the second heat sink fin group 12 are both stacked with a plurality of heat sink fins of exactly the same shape and structure, and the heat sink fins are parallel to each other and have gaps between them. This design increases the surface area of ​​the radiator, thereby improving the heat dissipation efficiency. The first heat sink fan 21 is perpendicular to the heat sink fins of the first heat sink fin group 11 and is arranged on the left side of the first heat sink fin group 11. Similarly, the second heat sink fan 22 is perpendicular to the heat sink fins of the second heat sink fin group 12 and is arranged on the left side of the second heat sink fin group 12. In order to better adapt to different space requirements, the first heat sink fin group 11 and the second heat sink fin group 12 are arranged in a rectangular parallelepiped shape.

This structure ensures that the slide bar 32 can move in the slide slot 31. Three concave points 332 are specifically provided on the slide slot 31 to achieve three different fixed gears between the cooling fan 2 and the cooling fin group 1 for operation. More or fewer concave points 332 may also be provided according to actual needs.

Furthermore, the expansion nail is provided with two limit protrusions arranged along the axis direction of the expansion nail corresponding to the expansion sleeve to prevent the expansion nail from falling off from the expansion sleeve, wherein the limit protrusion includes a guide portion close to the top of the expansion nail and a stop portion close to the end of the expansion nail, and a stop surface corresponding to the stop portion is provided in the expansion sleeve. Specifically, the function of the guide portion is to guide the expansion nail into the expansion sleeve to ensure that the expansion nail can be smoothly inserted into the expansion sleeve.
