[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: a new type of wind-collecting radiator, comprising: a siphon heat-conducting pipe 1, a sintered capillary structure 5 is arranged inside the siphon heat-conducting pipe 1, and a condensing medium 6 is filled in the sintered capillary structure 5 to achieve heat conduction through the condensing medium 6; a substrate 2, one side of which is suitable for fitting to a heat source, and the other side of which is fixed with the siphon heat-conducting pipe 1, a portion of the siphon heat-conducting pipe 1 protrudes from the substrate 2 and fixes a heat dissipation fin group 3, and a PAD4 is filled at the fitting position between the substrate 2 and the heat source, and it should be noted that the PAD4 is a heat-conducting silicone sheet; a heat dissipation fin group 3, one end of which faces the system air inlet, and is blown by the system air volume, so as to quickly blow away the heat emitted from the surface of the heat dissipation fin group 3.

[0029] The new type of air-gathering radiator with the above structure, after the heat source generates heat, the heat passes through the substrate 2 along the PAD4, and the substrate 2 transfers the heat to the siphon heat pipe 1, and the heat is brought to the heat dissipation fin group 3 through the siphon heat pipe 1, and then the wind is blown into the heat dissipation fins through the system air inlet, so that the wind can quickly take away the heat dissipated from the surface of the fins in the heat dissipation fin group 3. This structure makes full use of the limited environmental space for heat transfer, and dissipates the heat into the air through the air volume provided by the system, which solves the problem in traditional technology that it is difficult to gather and dissipate the air volume provided by the system in a specific space.

[0030] In the present embodiment, when the wind entering along the system air inlet is blown into the heat dissipation fin group 3, some of the wind is still unable to converge into the heat dissipation fin group 3. In order to increase the convergence of the wind, the heat dissipation fin group 3 is provided with a plurality of fins 31, and the plurality of fins 31 are distributed at intervals, and the plurality of fins 31 are arranged in a fan shape at one end facing the system air inlet, so that an air duct 32 is formed between adjacent fins 31. The fan-shaped end formed by the plurality of fins 31 can conveniently converge the wind, increase the air volume and flow speed, and blow into the heat dissipation fin group 3 along the air duct 32, thereby improving the wind convergence and heat dissipation effects.

[0031] In this embodiment, in order to further reduce the volume of the new wind-collecting radiator and increase the utilization rate of limited space, an embedding groove 7 is opened on each fin 31, and an installation groove 8 is opened on the side of the substrate 2 facing away from the heat source, so that the siphon heat pipe 1 can be embedded in the embedding groove 7 and the installation groove 8, and the siphon heat pipe 1 is fixed to the heat dissipation fin group 3 and the substrate 2, thereby achieving the effect of reducing the volume.

[0032] In this embodiment, in order to increase the thermal conductivity of the substrate 2 and reduce the heat accumulated between the substrate 2 and the heat source, the material of the substrate 2 is set to CU1100. The copper substrate 2 has a higher thermal conductivity and can effectively dissipate heat from the heat source, thereby improving the heat dissipation and thermal conductivity of the substrate 2.

[0033] In this embodiment, the siphon heat pipe 1, the base plate 2 and the heat dissipation fin group 3 are fixed together by soldering, so that heat conduction and heat dissipation can be effectively performed.

[0034] In this embodiment, in order to quickly fix the substrate 2 on the heat source and facilitate subsequent disassembly, a plurality of locking holes 9 are provided on the substrate 2, and the locking holes 9 can facilitate the insertion of threaded nails. During the installation process, the threaded nails can be inserted into the locking holes 9 and the screws can be driven into the heat source, thereby quickly fixing the substrate 2. During disassembly, the threaded nails can be rotated to take them out to facilitate subsequent disassembly.

[0035] In this embodiment, in order to increase the surface heat radiation, a nano-carbon layer 10 is sprayed on the siphon heat pipe 1 , the substrate 2 and the heat dissipation fin group 3 .

[0036] Working principle: After the heat source generates heat, the heat passes through the substrate 2 along the PAD4, and then the substrate 2 transfers the heat to the siphon heat pipe 1, and the heat is brought to the heat dissipation fin group 3 through the siphon heat pipe 1. The fan-shaped end composed of multiple fins 31 in the heat dissipation fin group 3 can converge the wind, increase the air volume and flow speed, and introduce the wind into the air duct 32, so that the wind can quickly take away the heat emitted from the surface of the fin 31. During installation, the threaded nail can be inserted into the locking hole 9, and the screw can be driven into the heat source, so as to quickly fix the substrate 2. During disassembly, the threaded nail can be turned to remove it to facilitate subsequent disassembly. This structure can maximize the system wind gathering within the limited space of the system, achieve high-efficiency heat dissipation, and ensure the normal operation of the product system.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
