[0003] In the prior art, there is a cold plate radiator with a publication number of CN2414588Y, which is composed of a substrate and a heat sink fixedly arranged on the heat dissipation surface of the substrate. The characteristics are as follows: the heat sink is composed of a metal sheet, and the root of each heat sink is bent to have a folded edge with the same fold angle, and the folded edge contacts the heat dissipation surface of the substrate. The heat sinks are arranged in parallel and alternately to form a heat sink group, and the heat sink group is integrally brazed and connected to the substrate. The heat sink has the following problems:

[0004] Generally, the shape of the heat sink is rectangular and equidistantly arranged on the heat sink. The heat sink is generally formed by solid one-piece casting, and air cooling is often used. The heat dissipation method is relatively simple, which leads to the problem of low heat dissipation efficiency.

[0005] In view of the above problems, we propose a heat sink with a spiral cavity inside. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The trapezoidal design of the heat dissipation fins provided in the utility model can increase the contact area between the heat dissipation fins and the heat dissipation wind, thereby improving the heat dissipation efficiency of the heat dissipation fins.

[0020] The connecting column provided in the utility model can be externally connected to cooling water, and the cooling water is introduced through one end of the cavity and flows inside the cavity to provide heat dissipation and cooling treatment for the heat sink seat and provide indirect heat dissipation treatment for the heat sink fins, and then the water is discharged through the other end of the cavity, which can improve the heat dissipation effect provided by water cooling for the heat sink.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] The heat sink is made of aluminum and can be used with a cooling fan to dissipate heat for some devices or electronic components, such as a computer host, power supply, etc.

[0029] A heat sink base 1 and a plurality of heat sink fins 2 integrally fixed on the heat sink base 1;

[0030] A cavity 3 is formed inside the heat sink base 1 , and both ends of the cavity 3 are connected with connecting columns 4 .

[0031] like Figure 1 As shown, the cross section of the heat dissipation fin 2 is set to a trapezoidal structure. The trapezoidal design of the heat dissipation fin 2 can increase the contact area between the heat dissipation fin 2 and the heat dissipation air, thereby improving the heat dissipation efficiency of the heat dissipation fin 2.

[0032] like Figure 2 and Figure 3 As shown, the cavity 3 is hollow and spiral, and the connecting column 4 is connected to the cavity 3. The connecting column 4 can be externally connected to cooling water. The cooling water is introduced through one end of the cavity 3 and flows inside the cavity 3 to provide heat dissipation and cooling treatment for the heat sink seat 1 and provide indirect heat dissipation treatment for the heat sink fins 2. The water is then discharged through the other end of the cavity 3, which can improve the heat dissipation effect provided by water cooling for the heat sink.

[0033] like Figure 1 and Figure 2 As shown, connecting sliders 7 are fixed on both sides of the sealing plate 5, and side grooves 6 are opened on both sides of the inner wall of the heat sink seat 1. The side grooves 6 correspond to the connecting sliders 7 and are adapted to each other. The connecting sliders 7 on both sides of the sealing plate 5 can be correspondingly inserted into the inside of the side grooves 6, and the sealing plate 5 can be completely pushed into the inside of the heat sink seat 1, and the heat sink seat 1 can be covered and closed, or the heat sink seat 1 and the sealing plate 5 can be separated, which can be used to clean impurities accumulated inside the cavity 3 with water or tools.

[0034] like Figure 2 As shown, four corners of the bottom of the heat sink seat 1 are provided with mounting screw holes 9, and a plurality of mounting screws 8 are passed through the interior of the sealing plate 5. The mounting screws 8 correspond to the mounting screw holes 9, and the threads are matched. The mounting screws 8 on the sealing plate 5 are matched with the mounting screw holes 9 of the heat sink seat 1, and the mounting screws 8 can be screwed into the interior of the mounting screw holes 9 accordingly, so that the heat sink seat 1 and the sealing plate 5 can be fixedly installed, and the sealing plate 5 can be installed on the heat sink seat 1.

[0035] Working principle: First, when in use, the connecting sliders 7 on both sides of the sealing plate 5 can be correspondingly inserted into the inside of the side grooves 6, and the sealing plate 5 can be completely pushed into the inside of the heat sink seat 1, and the heat sink seat 1 can be covered and closed. Then, the mounting screws 8 on the sealing plate 5 can be aligned with the mounting screw holes 9 of the heat sink seat 1, and the mounting screws 8 can be correspondingly screwed into the inside of the mounting screw holes 9, so that the heat sink seat 1 and the sealing plate 5 can be fixedly installed, and the sealing plate 5 can be installed on the heat sink seat 1;

[0036] Then, the connecting column 4 can be connected to cooling water externally, and the cooling water is introduced through one end of the cavity 3 and flows inside the cavity 3 to provide heat dissipation and cooling treatment for the heat sink seat 1 and provide indirect heat dissipation treatment for the heat dissipation fins 2, and then the water is discharged through the other end of the cavity 3. At the same time, the heat dissipation fins 2 can increase the contact area of ​​the heat dissipation air.
