Description

Technical Field

[0001] The utility model belongs to the technical field of magnesium material manufacturing, in particular to a magnesium alloy radiator. Background Art

[0002] A radiator is a device used to cool and dissipate heat from graphics cards. With the development of technology and market competition, more requirements are placed on radiators. Not only are the radiators required to have superior heat dissipation performance, but they are also required to fully meet the requirements of 3C products for high integration, lightness, miniaturization, anti-drop and impact, electromagnetic shielding and heat dissipation to satisfy brands or consumers.

[0003] Through the above analysis, the problems and defects of the existing technology are: the existing radiators cannot meet the requirements of 3C products for high integration, lightness, miniaturization, anti-drop and impact, electromagnetic shielding and heat dissipation.

[0004] Prior Art: A common heat sink design uses aluminum alloy as the heat sink material and a single fan design. Aluminum alloy is widely used due to its good thermal conductivity, while the single fan design is intended to simplify the structure and reduce costs.

[0005] Technical issues:

[0006] 1. Weight issue: Although aluminum alloy has good thermal conductivity, its density is greater than that of magnesium alloy. Aluminum alloy radiators of the same volume will be heavier, which is a problem for portable devices (such as laptops) and will affect the portability of the device.

[0007] 2. Cooling efficiency: A single fan design is not efficient enough to handle the large amounts of heat generated by high-performance computer hardware, especially under high load. In addition, if a fan fails, the entire cooling system will not function.

[0008] 3. Noise problem: In order to improve heat dissipation efficiency, the fan speed needs to be increased, but this will lead to increased noise and affect the user experience.

[0009] 4. Insufficient thermal management: There is no intelligent fan speed control, and the fan speed cannot be automatically adjusted according to the temperature of the computer, which will cause the computer to run at high temperature, affecting stability and efficiency. Utility Model Content

[0010] In view of the problems existing in the prior art, the utility model provides a magnesium alloy radiator.

[0011] The utility model is implemented as follows: a magnesium alloy radiator includes a fan, a shell, and a heat sink. The shell is arranged on the heat sink and is used to fix the fan; the fan is installed in the shell and is used to rotate for heat dissipation; the heat sink is placed at the bottom and is used to transfer the generated heat for heat dissipation.

[0012] Furthermore, the fan is designed to be speed-adjustable and the wind speed is adjusted in real time through a built-in temperature sensor.

[0013] Further, the heat sink is made of magnesium alloy metal; the heat sink is made of AZ91D magnesium alloy having excellent strength and corrosion resistance.

[0014] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the present utility model are as follows:

[0015] First, compared with existing technologies, magnesium alloy radiators have effectively solved these technical problems and achieved significant technological progress by optimizing material selection, heat sink design, fan design and intelligent speed regulation.

[0016] This heat sink is made of magnesium alloy. Magnesium alloy CPU heat sinks are strong, lightweight, low-density, and offer excellent heat dissipation and high pressure resistance. They fully meet the requirements of 3C products for high integration, lightweight, miniaturization, impact resistance, electromagnetic shielding, and heat dissipation. Their hardness is several times that of traditional plastic casings, yet they weigh only one-third as much.

[0017] Second, the design and embodiments of the magnesium alloy heat sink of the present invention have achieved significant technical progress, which is mainly reflected in the following aspects:

[0018] 1) Material selection: Magnesium alloy is selected as the material of the heat sink. Magnesium alloy has excellent thermal conductivity, light weight and high strength, which helps to improve heat dissipation efficiency and reduce overall weight.

[0019] 2) Heat sink design: The use of multi-layer stacking, corrugated shape or heat pipe connection design effectively increases the heat dissipation area and improves heat dissipation efficiency.

[0020] 3) Fan design: The fan adopts adjustable speed, double blades or brushless motor design, which can adjust the wind speed according to needs, provide stronger airflow, reduce noise and extend service life.

[0021] 4) Intelligent speed regulation: Automatically adjust the fan speed according to the computer's temperature, achieving more intelligent thermal management and improving the computer's operating efficiency and stability.

[0022] 5) Addition of heat sink: Adding heat sink between the fan and heat sink can better disperse the heat source, prevent the occurrence of hot spots, and improve the heat dissipation effect.

[0023] Through these technological advancements, magnesium alloy radiators can not only effectively reduce the operating temperature of the computer, improve stability and efficiency, but also extend the service life of the computer and enhance the user experience.

[0029] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] In view of the problems existing in the prior art, the present invention provides a magnesium alloy radiator, which will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, the magnesium alloy heat sink provided by the embodiment of the present invention includes a fan, a housing, and a heat sink. The housing is arranged on the heat sink for fixing the fan. The fan is installed in the housing for rotating to dissipate heat.

[0032] like Figure 2 As shown, the heat sink is placed at the bottom to transfer the generated heat and dissipate the heat.

[0033] The heat sink is made of magnesium alloy metal.

[0034] like Figure 3As shown, the magnesium alloy radiator provided by the embodiment of the present invention includes a fan 1 and a heat sink 2. The heat sink 2 is fixedly connected to one side of the fan 1, and the heat-generating components of the computer are fixedly connected to the other side of the fan 1. When the fan 1 is in an energized working state, the air flow first flows through the heat-generating components of the computer into the fan 1, and then the air flow flows out from the heat sink. In this process, the heat generated by the operation of the heat-generating components of the computer is transferred outward through the heat sink 3 with the help of the flow of air. The heat sink 3 is made of magnesium alloy metal.

[0035] Magnesium alloy CPU heat sinks are strong, lightweight, low-density, and offer excellent heat dissipation and high pressure resistance. They fully meet the requirements of 3C products for high integration, thinness, miniaturization, drop resistance, electromagnetic shielding, and heat dissipation. Their hardness is several times that of traditional plastic casings, yet they weigh only one-third of the latter.

[0036] Example 1:

[0037] In this embodiment, the heat sink 2 can be designed as a multi-layer stack to increase the heat dissipation area. The fan 1 can be designed to be adjustable in speed to increase the wind speed when higher cooling efficiency is required. In addition, the magnesium alloy of choice can be AZ91D, which has good strength and corrosion resistance.

[0038] Example 2:

[0039] In this embodiment, heat sink 2 can be connected to fan 1 via a heat pipe to more efficiently transfer heat. Fan 1 can be designed with two blades to provide stronger airflow. Furthermore, the magnesium alloy can be AM60B, which has high thermal conductivity and a low melting point, making it suitable for operation in high-temperature environments.

[0040] Example 3:

[0041] In this embodiment, the heat sink 2 can be designed with a corrugated shape to increase the contact area between the air and the heat sink, improving heat dissipation efficiency. Fan 1 can be designed with a brushless motor to reduce noise and extend service life. In this case, AM50 magnesium alloy can be selected because of its good plasticity and toughness, which allows for complex shapes.

[0042] Example 4:

[0043] In this embodiment, a heat sink can be added between fan 1 and heat sink 2 to better disperse the heat source. Fan 1 can be designed to automatically adjust the speed based on the computer's temperature. The magnesium alloy of choice can be AE44, as it has excellent stability and durability when continuously exposed to high temperatures.
