The two heat conduction tube groups have the same number and shape of heat conduction tubes, and the number, specification and material of the heat conduction base can be matched according to the heat dissipation requirements. The heat conduction tube is composed of a heat dissipation end inserted into the heat dissipation part, a heat conduction end directly in contact with the heat source, and a connection part connecting the heat dissipation end and the heat conduction end at both ends. The heat dissipation ends of the two heat conduction tube groups are inserted into the head of the heat dissipation part in a direction perpendicular to the heat dissipation fins and staggered oppositely. The heat conduction ends of the two heat conduction tubes are arranged side by side below the heat conduction base in a direction parallel to the heat dissipation fins. The heat conduction ends and the connection parts of the two heat conduction tube groups are arranged in a horn shape below the heat dissipation part. The high-efficiency radiator solution of this embodiment eliminates the horn fin group attached to both sides of the main fin of the existing server radiator and improves the pipe layout method, which not only effectively simplifies the radiator structure and reduces the volume of the radiator, thereby optimizing the space layout inside the chassis and reducing the difficulty of wiring inside the chassis, but also optimizes the arrangement of the dual heat pipe group inside and outside the heat dissipation part to increase the installation length of the heat pipe per unit volume of the radiator, thereby improving the heat dissipation efficiency of the radiator.

[0031] like Figure 1-3 As shown, in this embodiment, the two heat pipe groups are respectively arranged on the left and right sides of the heat dissipation part, and the heat conduction ends and the heat dissipation ends of the two heat pipe groups are located on the same side of the heat dissipation part. Of course, in other embodiments, the heat conduction ends can be cross-arranged under the heat dissipation part without affecting its heat dissipation efficiency.

[0032] like Figure 1-3 As shown, in this embodiment, the heat-conducting base is provided with a plurality of mounting grooves for placing the heat-conducting pipes side by side, and the mounting grooves match the number and shape of the heat-conducting pipes. One side of the heat-conducting end of the heat-conducting pipe is fixedly installed in the mounting groove, and the other side is formed by flattening the heat-conducting pipe to form a flat heat-conducting plane, and the heat-conducting plane is flush with the upper edge of the mounting groove, thereby increasing the contact area between the heat source and the heat-conducting plane to efficiently transfer heat to the heat-conducting end of the heat-conducting pipe; the radiator is provided with mounting holes that penetrate the heat dissipation part and the heat-conducting base from top to bottom in sequence, and fixing bolts are penetrated inside the mounting holes, and the heat-conducting base is installed under the heat dissipation part by the fixing bolts; in order to rationalize the structure, the heat base is provided with lifting blocks on the left and right sides of the mounting groove, and the lifting blocks are flush with the heat-conducting plane formed by the heat-conducting pipes, and three pairs of mounting holes for installing fixing bolts are equidistantly provided on the left and right lifting blocks of the heat-conducting base. Of course, the number and positions of the mounting holes can be determined according to needs in other embodiments.

[0033] Embodiment 2 of the present utility model:

[0034] In order to rationalize the layout and improve the heat dissipation efficiency, based on Example 1, this embodiment provides a high-efficiency heat sink, and optimizes the structure of the heat sink and the arrangement of the heat pipes. Figure 1-3As shown, the head of the heat dissipation part of this embodiment is provided with a stepped hollowing that is recessed upward relative to the heat-conducting base, and the heat-conducting pipe connecting part is provided with a first bend, a second bend and a third bend in an L-shaped bend in sequence, the first bend is located at the junction of the connecting part and the heat-dissipating end and is bent downward, one end of the second bend is connected to the first bend and the other end is bent toward one side of the radiator, and the third bend is connected to the second bend and is bent toward the tail of the heat-dissipating part along the heat-conducting base, wherein the second bend and the third bend of the heat-conducting pipe are accommodated and placed in the hollowing space provided at the head of the heat-conducting base. In the chassis heat dissipation scenario, the heat dissipation fan is provided corresponding to the head of the heat sink and blows air from the head of the heat sink to the tail along the direction of the heat-dissipating fins. Therefore, the 3D heat-conducting pipe with multiple bends and the stepped hollowing provided at the head of the heat sink are conducive to increasing the heat dissipation area of ​​the heat-conducting pipe and the heat-dissipating fins, enhancing the transfer of heat to the external environment, and thus improving the heat dissipation efficiency.

[0035] To further improve the heat dissipation efficiency, in this embodiment, the heat dissipation end of the heat pipe protrudes outward by 1.5 cm relative to the heat dissipation part. In other embodiments, a suitable length can be matched within the range of 0.1 cm-3.0 cm.

[0036] To further rationalize the structure, the height of the radiator in this embodiment is 5.0 cm. In other embodiments, the height of the radiator can be determined within a range of no more than 7.0 cm as needed to optimize the space layout in the chassis and reduce the difficulty of wiring in the chassis.

[0037] Embodiment 3 of the present utility model:

[0038] In order to improve the heat dissipation efficiency of the radiator, this embodiment further optimizes the structure of the heat pipe and the radiator on the basis of Embodiment 1. An oblate through hole for accommodating the heat pipe is formed in the heat dissipation part by using stamping technology. The heat dissipation end of the heat pipe is punched into an oblate circle corresponding to the oblate through hole, and is in close contact with the heat dissipation fin group of the heat dissipation part to ensure that the heat can be quickly transferred to the fins. In addition, in the chassis heat dissipation scenario, the cooling fan is arranged corresponding to the head of the radiator and blows air from the head to the tail of the radiator along the direction of the heat dissipation fins. The heat pipe punched into an oblate circle faces the wind source with its narrow side, thereby reducing wind resistance and increasing wind speed, thereby improving the heat dissipation efficiency of the heat dissipation fin group and the heat pipe.

[0039] Embodiment 4 of the present utility model:

[0040] This embodiment provides a server heat dissipation module based on embodiments 1-3. The server heat dissipation module is configured with a high-efficiency radiator, a fan heat dissipation unit and a server chip. The fan heat dissipation unit is correspondingly installed on the radiator head, and the server chip is correspondingly installed under the radiator heat conductive base and in contact with the heat conductive base.
