Technical Field
[0001] The utility model patent relates to the technical field of 3DVC radiators, and more specifically, to a non-brazed 3DVC radiator. Background Art
[0002] When a computer host is working, a large amount of heat will be generated. If this heat is not dissipated in time, it will cause the computer to freeze at best and burn the components of the host at worst. Therefore, a radiator needs to be set up to dissipate the heat of the internal components of the host, and the commonly used VC radiator can meet the heat dissipation requirements.
[0003] VC radiators are generally divided into 2D VC radiators and 3D VC radiators. The 2D VC radiator is a plate-type radiator that realizes heat conduction on a two-dimensional plane. The 3D VC radiator has heat pipes embedded in the radiator, evenly distributing heat on the radiator substrate or fins. At the same time, the heat pipes are connected to the fins, so that heat can be more effectively dissipated into the air through the entire radiator, realizing heat conduction on a three-dimensional plane.
[0004] For example, the prior patent with the publication number CN117712062A discloses a 3D VC radiator and its manufacturing method, including a housing composed of a VC upper cover and a VC lower cover.

[0025] Refer to Figures 1-4As shown, it is a preferred embodiment provided by the present utility model.
[0026] The non-brazed 3DVC radiator includes a blade member 1 and a VC substrate 2. The blade member 1 is arranged in a flat shape, a blade cavity is formed inside the blade member 1, a plate cavity is formed inside the VC substrate 2. The lower part of the blade member 1 is in diffusion welding butt joint with the VC substrate 2. The upper part of the blade member 1 extends in a direction away from the VC substrate 2, and the blade cavity is in communication with the plate cavity.
[0027] For the above non-brazed 3DVC radiator, since the blade member 1 and the VC substrate 2 are in diffusion welding butt joint without using solder, the cost is reduced and it is convenient for manufacturing. At the same time, during heat dissipation, through the communication between the blade cavity and the plate cavity, the VC substrate 2 absorbs heat and conducts it to the blade member 1. Under the action of the blade member 1, the area of heat interaction is greatly increased, which is convenient for dissipating heat into the air, thereby improving the heat dissipation effect and efficiency.
[0028] The blade cavity and the plate cavity are filled with a working medium, which is convenient for the transfer and release of heat, and improves the heat dissipation and cooling effect.
[0029] The working medium can be a refrigerant or a liquid such as water.
[0030] The blade member 1 includes an upper blade cover 11 and a lower blade cover 12. The upper blade cover 11 and the lower blade cover 12 are in diffusion welding butt joint, and a blade cavity is formed between the upper blade cover 11 and the lower blade cover 12. In this way, the production of the blade member 1 does not require solder, reducing the production cost of the blade member 1 and facilitating the manufacturing of the blade member 1.
[0031] The upper blade cover 11 and the lower blade cover 12 are respectively arranged in a flat shape and are respectively used for heat interaction. In this way, the contact area between the upper blade cover 11 and the lower blade cover 12 and the outside is increased, thereby increasing the area of heat interaction and improving the heat dissipation effect of the upper blade cover 11 and the lower blade cover 12.
[0032] The blade member 1 includes an upper blade capillary layer 13 and a lower blade capillary layer 14. The upper blade capillary layer 13 is laid on the inner wall of the upper blade cover 11, the lower blade capillary layer 14 is laid on the inner wall of the lower blade cover 12. The upper blade capillary layer 13 and the lower blade capillary layer 14 are in butt joint and integrally formed, and the upper blade capillary layer 13 and the lower blade capillary layer 14 are respectively used for conducting heat.
[0033] Under the combined action of the upper blade capillary layer 13 and the lower blade capillary layer 14, it is convenient for heat absorption and dissipation. At the same time, the upper blade capillary layer 13 and the lower blade capillary layer 14 help to reduce the thermal resistance and facilitate the conduction of heat, thereby improving the heat conduction effect and further improving the heat dissipation effect.
[0034] The blade member 1 includes a plurality of blade support columns which are arranged at intervals correspondingly, and both ends of each blade support column are arranged in butt joint with the blade upper cover 11 and the blade lower cover 12 respectively; under the action of each blade support column, the bearing capacity of the blade upper cover 11 and the blade lower cover 12 is improved, thereby improving the deformation resistance of the blade upper cover 11 and the blade lower cover 12, and further improving the service life of the blade member 1.
[0035] The VC substrate 2 includes a board upper cover 21 which has a board cover surface arranged horizontally; it is convenient for the arrangement of the blade member 1 and the copper tube 3.
[0036] The bottom of the blade upper cover 11 forms a blade upper surface, and the bottom of the blade lower cover 12 forms a blade lower surface. The blade upper surface and the blade lower surface are respectively arranged in a tiled and diffusion welding butt joint with the board cover surface; in this way, since the blade upper cover 11 and the blade lower cover 12 are first butt-jointed by diffusion welding, and then the blade upper surface and the blade lower surface are butt-jointed with the board cover surface by diffusion welding, it is convenient for the assembly of the blade member 1 and the VC substrate 2. At the same time, for the welding between the blade member 1 and the VC substrate 2, no solder is required, reducing the production cost of the 3D VC heat sink and facilitating the manufacture of the 3D VC heat sink.
[0037] The VC substrate 2 includes a board upper capillary layer 23 which is laid on the inner wall of the board upper cover 21. The board upper capillary layer 23 is used for conducting heat, and the board upper capillary layer 23 is synchronously butted and integrally formed with the blade upper capillary layer 13 and the blade lower capillary layer 14.
[0038] In this way, under the action of the board upper capillary layer 23, it is convenient for the heat interaction between the board upper cover 21 and the blade member 1, facilitating the conduction of heat and improving the heat dissipation effect and efficiency.
[0039] The VC substrate 2 includes a board lower cover 22 and a board lower capillary layer 24. The board upper cover 21 and the board lower cover 22 are butted by diffusion welding in the up and down direction; in this way, the blade upper cover 11 and the blade lower cover 12 are first butted by diffusion welding, and then the blade upper cover 11 and the blade lower cover 12 are synchronously butted with the board upper cover 21 by diffusion welding. Finally, the board upper cover 21 and the board lower cover 22 are butted by diffusion welding; the whole welding and assembly does not require solder. At the same time, it is convenient for the arrangement of the blade upper capillary layer 13, the blade lower capillary layer 14, the board upper capillary layer 23 and the board lower capillary layer 24.
[0040] The board lower capillary layer 24 is laid on the inner wall of the board lower cover 22. The board lower capillary layer 24 is used for conducting heat, and the board upper capillary layer 23 and the board lower capillary layer 24 are butted and integrally formed; under the action of the board lower capillary layer 24, it is convenient to absorb the heat of the heat source and conduct the heat to the board upper cover 21 and then to the blade member 1, improving the heat dissipation effect on the heat source.
[0041] The VC substrate 2 includes a plurality of board support columns, and each board support column is arranged at intervals correspondingly. The two ends of the board support column are respectively arranged in butt joint with the upper board cover 21 and the lower board cover 22. In this way, under the action of the board support column, the bearing capacity of the upper board cover 21 and the lower board cover 22 is improved, so as to improve the deformation resistance of the upper board cover 21 and the lower board cover 22, and further improve the service life of the VC substrate 2.

The lower part of the copper tube 3 is arranged in butt joint with the upper board cover 21, and the upper part of the copper tube 3 extends in the direction away from the upper board cover 21. A tube cavity is formed inside the copper tube 3, and the tube cavity is arranged in communication with the board cavity.
[0043] In this way, during heat dissipation, the VC substrate 2 absorbs heat and conducts it to the blade member 1 and each copper tube 3. Under the combined action of the blade member 1 and each copper tube 3, the heat dissipation paths are increased, and the heat interaction area is also increased, facilitating the dissipation of heat into the air, thereby improving the heat dissipation effect and efficiency.
[0044] A tube capillary layer is laid on the inner wall of the copper tube 3, and the tube capillary layer is used for conducting heat. The tube capillary layer is arranged in coherent butt joint and integrally formed with the upper board capillary layer 23. Under the action of the tube capillary layer, it helps to reduce the thermal resistance and facilitate the conduction of heat, thereby improving the heat dissipation effect and efficiency.
[0045] The non-soldering type 3D VC heat sink includes a plurality of blade members 1, and each blade member 1 is respectively in diffusion welding butt joint with the VC substrate 2, and the blade cavities of each blade member 1 are synchronously arranged in communication with the board cavity. In this way, through the cooperation of each blade member 1, the heat interaction area is greatly increased, facilitating the dissipation of heat into the air, thereby improving the heat dissipation effect and efficiency.
[0046] The number of blade members 1 can be one, two, or three. Based on the heat dissipation requirements, different numbers of blade members 1 are selected.
[0047] Of course, a plurality of blade members 1 and copper tubes 3 can also be combined, increasing the heat dissipation paths and the heat interaction area, facilitating the dissipation of heat into the air, thereby improving the heat dissipation effect and efficiency.
