Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile radiators, and in particular to a multi-layer aluminum profile radiator. Background Technology

[0002] With the continuous development of electronic devices, heat dissipation problems have become increasingly prominent, especially in fields such as high-performance computing, consumer electronics, and electric vehicles. Aluminum profiles are widely used in the field of heat sinks due to their excellent thermal conductivity and lightweight properties. The design and performance of heat sinks directly affect the stability and service life of equipment. With the continuous increase in the power consumption of electronic components, traditional aluminum profile heat sinks have gradually exposed many problems in terms of heat dissipation efficiency and structural design.

[0003] Firstly, existing aluminum profile heat sinks mostly use single-layer heat sinks, which have insufficient heat dissipation area and cannot meet the heat dissipation requirements of high-power components, leading to heat accumulation, decreased equipment performance, or even damage. Secondly, existing heat sinks have fixed structures, and multi-layer structures often use welding or one-piece molding designs, making cleaning and maintenance inconvenient. After long-term use, dust accumulation is difficult to remove, resulting in reduced heat dissipation performance. Therefore, we propose a multi-layer aluminum profile heat sink to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer aluminum profile radiator to solve the problems of insufficient heat dissipation area and inconvenient cleaning and maintenance caused by the fixed structure of existing aluminum profile radiators.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-layer aluminum profile heat sink, including a heat sink plate. The heat sink plate is made of aluminum and is formed by at least three layers stacked vertically. Each layer of the heat sink plate has heat dissipation fins distributed at intervals on its surface.

[0006] The plug-in posts are located at the four corners of the heat sink to connect adjacent heat sinks and form a vertical stacked structure. Heat pipes are embedded inside the plug-in posts and extend through all the heat sinks.

[0007] A cooling fan is installed on one side of the stacked heat sink to generate airflow that carries away heat from the heat sink.

[0008] Preferably, the heat sink and the plug are integrally formed, wherein the plugs on the upper and lower sides of the heat sink are male and female, which are plugged in and matched, and when the plugging is completed, the top of the heat sink fins is in close contact with the bottom of the upper heat sink.

[0009] Preferably, the heat dissipation fins have a trapezoidal cross-section, with the top thickness being half the bottom thickness, and the first ventilation channel on the surface having an inclination angle of 95 to 100 degrees.

[0010] Preferably, the heat dissipation fins further include a second ventilation channel, which is perpendicular to the first ventilation channel.

[0011] Preferably, the cooling fan is positioned directly opposite the second ventilation duct.

[0012] Preferably, the bottom of the plug is provided with a bolt, which is used to install the heat dissipation component with a thread.

[0013] Preferably, the heat pipe is a copper sintered capillary structure embedded inside the plug post, with the evaporation section of the heat pipe in contact with the bottom heat sink and the condensation section of the heat pipe protruding from above the top heat sink.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The multi-layer aluminum profile heat sink of this utility model has a significantly increased heat dissipation area through the vertical stacking design of three or more layers of aluminum heat dissipation plates, which effectively meets the heat dissipation needs of high power consumption components and has a significantly better heat dissipation effect than traditional single-layer aluminum profile heat sinks.

[0016] 2. The heat dissipation plate and plug-in post of the multi-layer aluminum profile heat sink of this utility model adopt a plug-in design, which allows each heat dissipation plate to be disassembled as needed, making it easy to clean the dust on the heat dissipation fins and extend the service life of the heat sink;

[0017] 3. The heat dissipation fins of the multi-layer aluminum profile heat sink of this utility model are provided with an inclined first ventilation channel and a vertical second ventilation channel, forming a cross-shaped airflow channel.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0025] This utility model provides a multi-layer aluminum profile heat sink. Please refer to [link / reference]. Figures 1-3 The system includes a heat sink 1, which is made of aluminum and is formed by at least three layers stacked vertically, with heat dissipation fins 2 spaced apart on the surface of each heat sink 1; a connector 3, which is located at the four corners of the heat sink 1 and is used to connect adjacent heat sinks 1 to form a vertical stacked structure, with heat pipes 4 embedded inside the connector 3 and extending through all the heat sinks 1; and a cooling fan 5, which is installed on one side of the stacked heat sinks 1 and is used to generate airflow to remove heat from the heat sinks 1.

[0026] The heat sink 1 and the plug-in post 3 are integrally formed. The plug-in post 3 on the upper and lower sides of the heat sink 1 is divided into male and female heads, which are plugged in and connected. When the plug-in is completed, the top of the heat sink fin 2 is in close contact with the bottom of the upper heat sink 1. The heat sink fin 2 has a trapezoidal cross-section, and the thickness of the top is 1 / 2 of the thickness of the bottom. The first ventilation channel 201 on the surface has an inclination angle of 95~100 degrees. The heat sink fin 2 also includes a second ventilation channel 202, which is perpendicular to the first ventilation channel 201. The cooling fan 5 is directly facing the second ventilation channel 202. The bottom of the plug-in post 301 is provided with a bolt 301, which is threaded to the component to be cooled. The heat pipe 4 is a copper sintered capillary structure, which is embedded in the plug-in post 3. The evaporation section of the heat pipe is in contact with the bottom heat sink 1, and the condensation section of the heat pipe protrudes from the top heat sink 1.

[0027] It should be noted that the heat sink 1 is an aluminum plate with a thickness of 2 mm. The surface is provided with spaced heat dissipation fins 2. The heat dissipation fins 2 are 15 mm high and 3 mm apart. The three heat sinks 1 are stacked vertically by the plug-in post 3. The top of the heat dissipation fins 2 of each heat sink 1 is in close contact with the bottom of the heat sink 1 above, forming a continuous heat conduction path. The bottom heat sink 1 is in direct contact with the component to be cooled (CPU) and is fixed by bolts 301. The bolts are connected to the mounting holes of the component to be cooled (CPU) through the threaded holes at the bottom of the plug-in post 3. The heat sink is installed firmly and the contact thermal resistance is reduced.

[0028] Preferably, the plug post 3 is cylindrical with a diameter of 8 mm and has a heat pipe 4 embedded inside. The top and bottom of the plug post 3 are designed with male and female plug-in structures. Adjacent heat insulation plates are connected by this plug-in method. After plugging, it is fixed by a buckle to ensure the structure is stable. The plug post 3 is located at the four corners of the heat sink 1 and runs through all the heat sink 1 to form a vertically stacked support structure. The plug post 3 not only plays a connecting role, but also quickly conducts heat through the internal heat pipe 4 to improve the overall heat dissipation performance.

[0029] Preferably, the heat pipe 4 is a copper sintered capillary structure with a diameter of 6 mm. The evaporation section contacts the bottom heat sink 1, and the condensation section extends to the top heat sink 1, protruding about 10 mm. The heat pipe is embedded in the plug post 3 and is tightly attached to the heat sink 1 with thermal grease. The heat pipe uses the phase change principle to quickly conduct heat, rapidly transferring the heat generated by the CPU to the top heat sink and reducing heat accumulation.

[0030] Preferably, the heat dissipation fin 2 has a trapezoidal cross-section with a top thickness of 0.5 mm and a bottom thickness of 1 mm. The surface is provided with a first ventilation channel 201 with an inclination angle of 95 degrees and a second ventilation channel 202 perpendicular to the first ventilation channel. The heat dissipation fin 2 is integrally formed on the corresponding heat dissipation plate 1. The trapezoidal design can increase the heat dissipation surface area and guide airflow more smoothly through the fins, reducing airflow resistance. In addition, its trapezoidal bottom is wider, providing better support and stability, and the structural strength is better.

[0031] In summary, this multi-layer aluminum profile heat sink significantly increases the heat dissipation area and improves the heat dissipation effect through the vertical stacking design of three or more layers of aluminum heat dissipation plates, making it particularly suitable for the heat dissipation needs of high-power components. Simultaneously, the heat dissipation plates and connectors are designed for easy disassembly and cleaning of dust on each heat dissipation plate, extending the lifespan of the heat sink. Furthermore, the heat dissipation fins are equipped with an inclined first ventilation channel and a vertical second ventilation channel, forming a cross-shaped airflow channel. Combined with the airflow direction of the cooling fan, this reduces airflow loss and improves airflow utilization. Only a single fan is needed to achieve all-around heat dissipation, further optimizing heat dissipation efficiency.

[0032] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
