Description

3D printing water-cooled fin heat sink

The model relates to a fin radiator, in particular to a 3D printing water-cooled fin radiator.

The old heat dissipation technologies include heat sinks, heat conduction elbows, fans, condensers, liquid storage chambers, capillary tubes and other methods. The heat sink is a common way to dissipate heat, which uses the temperature difference to conduct heat into the air, but there is no water cooling on the heat sink, and the heat dissipation effect is not as good as the new type of heat dissipation effect. The manufacturing process of the condenser is complicated. The airflow of the fan is not easy to control and diverges. The capillary tube is used on the heat sink to allow the cooling liquid to flow through and take away heat. Although the heat dissipation effect is better, the capillary tube can only transport the liquid upwards, which is limited in direction. The flow channel direction of the present invention is not limited to the up and down direction.

Once these old technologies are completed, the shape is fixed. If the shape or state of the heat source changes in the future, they will not be able to respond to the change. They must be re-made, which is costly. At the same time, they are not integrally formed, and when the heat source vibrates, they are prone to damage. The production process of these old technologies is more complicated than that of 3D printing. These old technologies cannot recycle materials and re-manufacture them, and the cost is relatively expensive.

The main purpose of the present invention is to provide a 3D printing water-cooled fin heat sink, which is used to improve the existing technology, when the heat source type or state changes, they cannot respond to the change. And when the heat source vibrates, it is easy to cause damage, and their production process is more complicated than 3D printing, and these old technologies cannot recycle materials.

In order to achieve the above objectives, a 3D printing water-cooled fin heat sink includes a base, a fin set, a water cooling system, and a kinetic energy generator. The base is a three-dimensional shape. The fin group is arranged on the upper surface of the base. The fin group includes a single fin or a plurality of fins. The thickness of the fin is lamella, and the shape is not limited. The size and number of fins are mainly such that the integral heat sink will not tip over. The water cooling system is a tubular flow channel system. The tubular flow channel system is divided into two subsystems. The base subsystem is arranged inside the base, and the fin group subsystem is arranged inside the fins. The two subsystems communicate with each other. The base subsystem can be Single flow channel or mesh flow channel, the fin group subsystem can be a single flow channel or mesh flow channel. The surface of the 3D printing water-cooled fin radiator has an inlet and an outlet connected to the water cooling system, the inlet and outlet Cannot overlap. The kinetic energy generator is installed near the exit and outside the 3D printing water-cooled fin radiator. The beneficial effects of the new type can be: when the heat source type or state changes, the fins can be enlarged, reduced, increased the number of pieces, reduced the number of pieces, and the flow channel cross-sectional shape can be changed without limitation, and it is integrally formed, which is not easy to be caused by the heat source. Vibration causes damage and liquid leakage, and they are printed by a 3D printer. The production process is simpler than the prior art. At the same time, the fins of the present invention have runners and have better heat dissipation effects.

Please refer to FIG. 1, which is a schematic diagram of the structure of the new 3D printing water-cooled fin heat sink. As shown in Fig. 1, the 3D printing water-cooled fin heat sink of the present invention can be applied to heat source generators surrounded by materials to dissipate heat, but it is not limited to this. The 3D printing water-cooled fin heat sink 1 includes a base 11, a fin group 12, a water cooling system 13, an inlet 14, an outlet 15 and a kinetic energy generator 16.

The 3D printing water-cooled fin heat sink 1 of the present invention is integrally formed and can be installed near the heat source to reduce the strain caused by stress. Therefore, the damage of the 3D printing water-cooled fin heat sink 1 caused by the heat source vibration can be reduced. The new model contains an integrally formed runner, because there are runners on the fins, the heat dissipation effect is good; the new 3D printing water-cooled fin radiator is not limited to whether it is directly attached to the heat source; if the new model is attached to the heat source When the temperature of the present invention does not reach the melting point of the 3D printing water-cooled fin radiator material, the present invention can also stick around the heat source. Sometimes it must be remade The heat exchanger can process the new model, recycle the materials, and reproduce the new model, which can save materials and costs.

The base 11 is a cubic block, but the shape is not limited to this, and depends on actual needs.

The fin group 12 is arranged on the upper surface of the base 11, and is a single fin or several fins as thin slices. The shape is not limited, and the number of fins is not limited. The size and number of the fins are mainly based on the new type without tipping. The new model can enlarge and shrink the fins according to actual needs, and the enlargement is not limited to the original fin itself being enlarged upwards, and an enlarged fin body can also be added to the original fin body, but it should be enlarged. The fin body can create an angle with the original fin body. As shown in Figure 2, the method of enlargement is to mill the upper end of the original fin to the red line first, and then print the new fin body above the original fin body, and the flow channel in the new fin body is the same as the original fin body. The flow passages of the fin body are connected, and the diameter of the two flow passages is the same.

If the 3D printer cannot print the new fin body on the original fin body after milling, the new fin body can be printed separately to merge the old and new fin body.

As the heat source may be added above the original heat source or the original heat source is scrapped and the newly purchased heat source has a larger surface area, the radiator must be enlarged. This method can be used without the need to make a new model to save costs. Because the original heat source is scrapped and the newly purchased heat source has a small surface area, the radiator must be reduced. This method can be used without the need to make a new model to save costs.

The concept of adding fins 121 and reducing fins 121 is shown in Fig. 3. The method of adding fins 121 is to drill two holes in the base 11 of the present invention. A new fin 121 is printed on the upper part of the two holes, as shown in Figure 4. It is not limited to adding fins on the top of the base 11, and fins can be added on the sides of the fins. The method is to drill two holes on the side of the original fins and print the new fins beside the two holes. This method is applied to the heating source near the heat source sometimes, there is no need to re The production of this model saves costs. If the 3D printer cannot print a new fin near the hole, you can print the new fin separately, and then merge the new fin with the part near the hole.

The method of reducing the fins 121 is to mill out the fins 121 to be removed and fill the holes with 3D printing. This method is applied when the heat source type or state changes, so there is no need to reproduce the new model, which saves costs.

Because it is 3D printing, the width of the flow channel of the water cooling system 13 can be designed in advance, and the shape of the flow channel section is not limited. Different positions can have different flow channel section shapes, and the actual cooling effect is the best.
