[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] See Figure 1-9 The figure shows a high-efficiency heat sink, which includes a first fin group 1, a second fin group 2, a heat-conducting base 3 mounted at the lower end of the first fin group and configured to contact a heat source, and a heat-conducting pipe 4 passing through the second fin group 2. The heat-conducting pipe 4 has a heat-conducting portion 41 at its lower end that contacts the heat source. The heat-conducting portion 41 is embedded in the lower end of the heat-conducting base 3, and the plane of the lower end of the heat-conducting portion 41 is flush with the lower end surface of the heat-conducting base 3. When the lower end surface of the heat-conducting base 3 contacts the heat source, the plane of the lower end of the heat-conducting portion 41 also contacts the heat source. This allows the plane of the lower end of the heat-conducting portion 41 and the lower end surface of the heat-conducting base 3 to contact the heat source simultaneously, thereby achieving efficient heat conduction, thereby transferring heat to the first fin group 1 and the second fin group 2, which dissipate the heat.

[0030] The first fin group 1 is formed by a plurality of first fins 11 vertically stacked together, wherein a first heat dissipation gap 10 in a vertical direction is formed between two adjacent first fins 11. Similarly, the second fin group 2 has the same structure as the first fin group 1, and the second fin group 2 is formed by a plurality of second fins vertically stacked together, wherein a second heat dissipation gap in a vertical direction is formed between two adjacent second fins.

[0031] In order to achieve a more efficient heat dissipation effect, the following design is also made: a first fan 5 is provided at the upper end of the first fin group 1, and the first fan 5 is placed above the first heat dissipation gap 10; the thermal seat 3 is provided with a plurality of heat conduction holes 31 passing through its upper and lower end surfaces, and each heat conduction hole 31 corresponds to and is connected to at least one first heat dissipation gap 10; when the first fan 5 is working, the first fan 5 draws the heat / hot air derived from the heat conduction hole 31 upward out of the first fin group 1 through the first heat dissipation gap 10. That is to say, the utility model can simultaneously contact the heat source through the plane of the lower end of the heat-conducting part 41 in the heat-conducting pipe 4 and the lower end surface of the heat-conducting seat 3, thereby forming efficient heat conduction, so as to transfer heat to the first fin group 1 and the second fin group 2, and the second fin group 2 dissipates the heat, and the first fan 5 cooperates with the first fin group 1 to dissipate the heat, wherein the first fan 5 can quickly exhaust the first heat dissipation gap 10 in the vertical direction to dissipate heat, and its heat dissipation effect is excellent; at the same time, since the heat-conducting seat 3 is provided with a plurality of heat-conducting holes 31 passing through its upper and lower end surfaces, each heat-conducting hole 31 corresponds to and is connected to at least one first heat dissipation gap 10; when the first fan 5 is working, the first fan 5 draws the heat / hot air derived from the heat-conducting hole 31 upward out of the first fin group 1 through the first heat dissipation gap 10, which can further enhance the heat dissipation effect and achieve the purpose of efficient heat dissipation.

[0032] The lower end of the heat-conducting hole 31 is directly connected to the heat source, or the heat-conducting hole 31 is directly connected to the gap between the lower end surface of the heat-conducting seat 3 and the heat source, wherein the gap is the gap between a part of the lower end surface of the heat-conducting seat 3 and the heat source, and most of the lower end surface of the heat-conducting seat 3 is in contact with the heat source.

[0033] The assembly structure of the heat conducting seat 3 and the heat conducting part 41 is as follows:

[0034] The lower end of the heat conducting base 3 is provided with a plurality of inlay grooves 32 extending through both sides. These inlay grooves 32 are arranged in parallel. The heat conducting portion 41 is inlaid and installed in the inlay grooves 32 through an interference fit, which provides a stable assembly structure. The heat conducting holes 31 are distributed outside the inlay grooves 32 on both sides. In this embodiment, the heat conducting holes 31 are distributed in two rows, one on each side of the inlay groove 32.

[0035] In order to ensure that the assembly of the heat-conducting pipe 4 and the heat-conducting seat 3 is more stable, the following improvements have been made: a first pressing plate 33 and a second pressing plate 34 are further provided on both sides of the lower end of the heat-conducting seat 3. The first pressing plate 33 and the second pressing plate 34 are respectively pressed on the two ends of the heat-conducting part 41 to limit the heat-conducting pipe 4, wherein at least one of the first pressing plate 33 and the second pressing plate 34 is pressed on the plane of the lower end of the heat-conducting part 41, so that the heat-conducting part 41 can be stably positioned in the heat-conducting seat 3, thereby improving the stability of the assembly structure.

[0036] The first pressing plate 33 and the second pressing plate 34 are both fixed to the lower end of the heat conducting base 3 by screws, and the assembly structure is simple and the installation is convenient.

[0037] The heat source is a chip 61 disposed on the PCB board 6 , particularly a high-power chip 61 .

[0038] There are two second fin groups 2, which are distributed on the first fin group 1 and form a gap between the first fin group 1. Both ends of the heat pipe 4 are respectively passed through and fixed in the two second fin groups 2.

[0039] A second fan 7 is also provided at the upper end of the second fin group 2, wherein the second fan 7 is aligned with the second heat dissipation gap of the second fin group 2. When the second fan 7 is working, the heat in the second fin group 2 is gathered through the second heat dissipation gap, thereby achieving a high-speed heat dissipation effect.

[0040] The PCB board 6, first fin set 1, second fin set 2, first fan 5, and second fan 7 are all mounted within a housing 8, forming a stable whole that is more convenient to use. The housing 8 is also provided with a heat dissipation vent 81 on the outside to expose the first fin set 1 and the second fin set 2. The upper end of the housing 8 is provided with a first window 82 and a second window 83, through which the first fan 5 and the second fan 7 are exposed, respectively.

[0041] The first fan 5 includes a first fan blade 51, which includes a first hub 511 and a plurality of first blades 512 radially distributed around the periphery of the first hub 511. The first blade 512 is formed with a plurality of wind-cutting ribs 501, and an air guide groove 502 is formed between two adjacent wind-cutting ribs 501. The design of the wind-cutting ribs 501 and the air guide groove 502 can increase the speed of the first fan blade 51, reduce wind resistance, and thereby improve the air production efficiency of the first fan blade 51. The front edge of the first blade 512 is also provided with an outwardly extending wind-cutting flange 503, which allows the first blade 512 to cut air more smoothly, further reducing wind resistance, and thereby improving the air production efficiency of the first fan blade 51.

[0042] In summary, the utility model can form efficient heat conduction by simultaneously contacting the heat source with the plane of the lower end of the heat-conducting portion 41 in the heat-conducting pipe 4 and the lower end surface of the heat-conducting seat 3, so as to transfer heat to the first fin group 1 and the second fin group 2, and the second fin group 2 dissipates the heat, and the first fan 5 cooperates with the first fin group 1 to dissipate the heat, wherein the first fan 5 can quickly exhaust the first heat dissipation gap 10 in the vertical direction to dissipate heat, and its heat dissipation effect is excellent; at the same time, since the heat-conducting seat 3 is provided with a plurality of heat-conducting holes 31 passing through its upper and lower end surfaces, each heat-conducting hole 31 corresponds to and is connected to at least one first heat dissipation gap 10; when the first fan 5 is working, the first fan 5 draws the heat / hot air derived from the heat-conducting hole 31 upward out of the first fin group 1 through the first heat dissipation gap 10, which can further enhance the heat dissipation effect and achieve the purpose of efficient heat dissipation.

[0043] The present invention also proposes a second structure, which is as follows:

[0044] A high-efficiency radiator comprises: a fin group formed by vertically stacking a plurality of fins, a heat-conducting seat mounted at the lower end of the fin group and used to contact a heat source, and a heat-conducting pipe passing through the fins, wherein a vertical heat dissipation gap is formed between two adjacent fins, and the lower end of the heat-conducting pipe has a heat-conducting portion that contacts the heat source, and the heat-conducting portion is embedded and mounted at the lower end of the heat-conducting seat, and the plane of the lower end of the heat-conducting portion is flush with the lower end surface of the heat-conducting seat, so that when the lower end surface of the heat-conducting seat contacts the heat source, the plane of the lower end of the heat-conducting portion also contacts the heat source at the same time, so that the heat-conducting portion The plane at the lower end and the lower end surface of the heat conducting seat contact the heat source at the same time, thereby forming efficient heat conduction, and then transferring the heat to the first fin group and the second fin group, which dissipate the heat. A fan is provided at the upper end of the fin group, and the fan is placed above the heat dissipation gap; the heat conducting seat is provided with a plurality of heat conducting holes passing through the upper and lower end surfaces thereof, and each heat conducting hole corresponds to and is connected to at least one heat dissipation gap; when the fan is working, the fan draws the heat / hot air derived from the heat conducting hole upward out of the fin group through the heat dissipation gap. The utility model can form efficient heat conduction by making the plane of the lower end of the heat conducting part in the heat conducting pipe contact the heat source with the lower end surface of the heat conducting seat at the same time, so as to transfer the heat to the fin group, and the fan cooperates with the fin group to dissipate the heat, wherein the fan can quickly draw air from the heat dissipation gap in the vertical direction to dissipate heat, and its heat dissipation effect is excellent; at the same time, since the heat conducting seat is provided with a plurality of heat conducting holes penetrating the upper and lower end surfaces thereof, each heat conducting hole corresponds to and is connected with at least one heat dissipation gap; when the fan is working, the fan draws the heat / hot air derived from the heat conducting holes upward out of the fin group through the heat dissipation gap, which can further enhance the heat dissipation effect and achieve the purpose of efficient heat dissipation.

[0045] That is to say, the difference between the high-efficiency radiator of the second structure and the high-efficiency radiator of the first structure shown is that the high-efficiency radiator of the second structure adopts a fin group, and the heat pipe is bent upward to pass through the fin group, and a fan is adopted. Apart from this, the other structures are the same and can achieve the same technical effects, so they will not be elaborated here.
