Description

Technical Field

[0001] This utility model relates to the field of heat sink technology, and in particular to an aluminum heat sink. Background Technology

[0002] A heat sink is a device used to dissipate heat from electronic components in electrical appliances that are prone to overheating. They are mostly made of aluminum alloy, brass, or bronze and can be in the form of plates, sheets, or multiple sheets. For example, the CPU in a computer requires a fairly large heat sink, and the power transistors, horizontal output transistors, and power amplifier transistors in a television all require heat sinks.

[0003] Generally, when using a heat sink, a layer of thermal grease is applied to the contact surface between the electronic component and the heat sink. This allows the heat generated by the component to be more effectively conducted to the heat sink, and then dissipated into the surrounding air by the heat sink.

[0004] In existing technologies, heat sinks mainly dissipate heat by conducting heat. However, existing heat sinks are made of aluminum and have a single heat dissipation efficiency. Relying on only one heat dissipation capability results in low heat dissipation efficiency.

[0005] Therefore, it is necessary to provide an aluminum heat sink to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides an aluminum heat sink that solves the problem that existing heat sinks, made of aluminum, have limited heat dissipation efficiency due to their single heat dissipation capability.

[0007] To solve the above-mentioned technical problems, this utility model provides an aluminum heat sink, comprising: a heat dissipation block;

[0008] A heat exchange device, wherein multiple heat exchange devices are equidistantly installed on one side of the surface of the heat sink block, each heat exchange device including heat sink fins and heat dissipation channels, wherein multiple heat sink fins are equidistantly installed on one side of the surface of the heat sink block, and multiple heat dissipation channels are sequentially and equidistantly opened on the surface of the heat sink fins from top to bottom.

[0009] A liquid inlet tank is provided inside the heat sink, and a plurality of connecting holes are provided on one side of the surface of the liquid inlet tank.

[0010] An inlet pipe is provided on one side of the top of the heat sink, and a drain pipe is provided on the other side of the top of the heat sink.

[0011] Preferably, the connecting hole connects into the interior of the heat dissipation fins.

[0012] Preferably, mounting ears are provided on both sides of the outer surface of the heat sink.

[0013] Preferably, one end of both the inlet pipe and the outlet pipe is controlled by an external liquid pump to control the liquid flow.

[0014] Preferably, the heat dissipation channel is in the shape of a parallelogram.

[0015] Preferably, a support device is provided around the surface of the heat dissipation fins. The support device includes a support tube and heat dissipation protrusions. The support tube is fixedly installed on the outer surface of the heat dissipation fins, and a plurality of heat dissipation protrusions are provided on the outer surface of the support tube.

[0016] Preferably, both the support tube and the heat dissipation bump are made of copper alloy.

[0017] Compared with related technologies, the aluminum heat sink provided by this utility model has the following beneficial effects:

[0018] This invention provides an aluminum heat sink. By creating a liquid inlet groove and connecting holes inside the heat sink block and heat sink fins, condensate is transported to these grooves and holes via an inlet pipe and a outlet pipe, carrying away heat from the surface of the heat sink block and heat sink fins. This device has a simple structure, high practicality, and effectively improves heat dissipation efficiency. As the condensate flows within the inlet groove and connecting holes, it fully absorbs heat from the heat sink block and heat sink fins, and the heat-absorbing condensate is discharged through the outlet pipe, forming a continuous heat dissipation cycle. Simultaneously, the heat sink block and multiple heat sink fins achieve self-heating. Multiple heat dissipation channels on the surface of the heat sink fins further increase airflow efficiency. The heat sink and liquid cooling work together to improve heat dissipation, solving the problem of single heat dissipation efficiency in existing heat sinks and effectively improving the overall heat dissipation performance of this electrically heated aluminum heat sink.

[0033] The connecting hole 7 connects into the interior of the heat dissipation fin 21.

[0034] Mounting lugs 3 are provided on both sides of the outer surface of the heat sink 1.

[0035] The liquid flow at one end of both the inlet pipe 4 and the outlet pipe 5 is controlled by an external liquid pump.

[0036] The heat dissipation channel 22 is in the shape of a parallelogram.

[0037] During use, a layer of thermally conductive silicone grease is applied to the contact surface between the electronic component and the heat sink 1, so that the heat generated by the component can be more effectively conducted to the heat sink 1, and then dissipated into the surrounding air through the heat sink fins 21.

[0038] Both the heat sink 1 and the heat sink fins 21 are made of aluminum alloy, which provides good heat dissipation.

[0039] The connecting hole 7 connects to the interior of the heat sink fin 21, and the connecting hole 7 is connected to the liquid inlet 6. By opening the liquid inlet 6 and the connecting hole 7, the production cost of the heat sink 1 and the heat sink fin 21 is reduced.

[0040] The heat dissipation channel 22 is in the shape of a parallelogram, and the inner walls on the upper and lower sides are inclined to increase the airflow velocity and improve the heat dissipation effect.

[0041] The working principle of the aluminum heat sink provided by this utility model is as follows:

[0042] During operation, the device is first installed on the surface of the component by mounting ear block 3 and bolts. Coolant is controlled to enter the inside of the inlet tank 6 of the heat sink 1 by the inlet pipe 4 and the liquid pump. The coolant flows inside the inlet tank 6 and the connecting hole 7, carrying away the heat of the heat sink 1 and the heat sink fins 21.

[0043] Compared with related technologies, the aluminum heat sink provided by this utility model has the following beneficial effects:

[0044] This invention provides an aluminum heat sink. By creating an inlet groove 6 and a connecting hole 7 inside the heat sink block 1 and heat sink fins 21, condensate is transported to the inlet groove 6 and connecting hole 7 via an inlet pipe 4 and a drain pipe 5, allowing it to circulate and remove heat from the surface of the heat sink block 1 and heat sink fins 21.

[0045] Second Embodiment

[0046] Please refer to the following: Figure 5 and Figure 6Based on the aluminum heat sink provided in the first embodiment of this application, the second embodiment of this application proposes another aluminum heat sink. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0047] Specifically, the second embodiment of this application provides an aluminum heat sink that is different in that a support device 8 is provided around the surface of the heat sink fin 21. The support device 8 includes a support tube 81 and heat dissipation protrusions 82. The support tube 81 is fixedly installed on the outer surface of the heat sink fin 21, and a plurality of heat dissipation protrusions 82 are provided on the outer surface of the support tube 81.

[0048] Both the support tube 81 and the heat dissipation bump 82 are made of copper alloy.

[0049] The working principle of the aluminum heat sink provided by this utility model is as follows:

[0050] During operation, a support device 8 is first set around the two heat dissipation fins 21. The support tube 81 supports the two heat dissipation fins 21. The setting of the support device 8 not only enhances the structural stability of the heat dissipation fins 21, but also the support tube 81 and the heat dissipation protrusions 82 on its surface are made of copper alloy. Copper alloy has high thermal conductivity and can quickly conduct heat away from the heat dissipation fins 21, further improving the heat dissipation efficiency.

[0051] When the condensate flows in the inlet tank 6 and the connecting hole 7 and carries away the heat from the heat sink 1 and the heat sink fins 21, the heat sink protrusions 82 of the support device 8 can also assist in heat dissipation, so that the heat from the edge of the heat sink fins 21 can be dissipated into the surrounding air more quickly. In combination with the heat dissipation of the heat sink 1 and the multiple heat sink fins 21 themselves and the liquid cooling method, the heat dissipation effect is improved in all aspects.

[0052] Compared with related technologies, the aluminum heat sink provided by this utility model has the following beneficial effects:

[0053] This utility model provides an aluminum heat sink. By setting a support device 8 around the two heat sink fins 21, and the support tube 81 supporting the two heat sink fins 21, the setting of the support device 8 not only enhances the structural stability of the heat sink fins 21, but also the heat dissipation protrusions 82 on it and its own support tube 81 can play an auxiliary role in heat dissipation, further improving the heat dissipation performance of the entire heat sink, improving the practicality of the device, and improving the heat exchange efficiency between the heat sink and the air, thereby enhancing the heat dissipation performance of the entire electric heating aluminum heat sink.
