Description

No base radiator

The invention relates to a design of a baseless heat sink, in particular to an improved design of a heat-absorbing end of a plurality of heat pipes which is adjacent and seamlessly arranged without a joint.

A heat sink having a heat pipe mainly includes a heat sink module, a plurality of heat pipes and a metal base, and the base is attached to the heat source by the base, and the heat temperature is transmitted from the base to the heat sink module through the heat pipe to achieve the transfer. The purpose of heat dissipation for heat temperature; as for the combination of the base and the heat pipe, it is often necessary to use a solder medium such as solder paste to complete the soldering, but the heat pipe and the base are often made of different materials, so the plating must be processed before welding. Therefore, the processing is complicated, the cost is increased, the assembly is inconvenient, and it is not environmentally friendly, and the base of the radiator is a solid metal block, which is not only heavy and bulky, but also has a large metal consumption, which also leads to high manufacturing costs.

Furthermore, the conventional heat sink is provided with a relative groove on the base for the plurality of heat pipes to be respectively inserted and coupled, but the space between the grooves of the base is spaced, so that the heat pipes are also spaced apart after being embedded, that is, the heat pipes are It is not possible to closely arrange the adjacent rows, and because of the spacing, the number of heat pipes can be reduced, and the heat transfer between the heat pipes is not good. The heat pipes located outside are unable to effectively exert heat transfer effect because they are relatively far away from the heat source. And there is a gap with the inner heat pipe, so it is not conducive to mutual heat transfer.

The main purpose of the present invention is to provide a design of a baseless heat sink, comprising more than one heat sink module and two or more multiple heat pipes, especially at the bottom of the heat sink forming the heat sink module. a tightly fitting groove, and a supporting rib having a depth less than the groove between the adjacent tight fitting grooves, so that the heat absorbing end of the heat pipe is tightly fitted into the tight fitting groove of the heat sink, and then after being flattened by extrusion, The plurality of heat pipes can be formed into a flat and juxtaposed adjacent joint state, so as to achieve a complete flattening configuration combination of the plurality of heat pipes, ensuring that there is no gap between the heat pipes, so that the heat source can directly dissipate heat directly through the plurality of flat heat pipes. It can increase the capacity of the heat pipe, greatly reduce the volume and weight of the heat sink, and save metal consumables to reduce costs, which is more convenient for packaging and transportation.

A secondary object of the present invention is to provide a design of a baseless heat sink, wherein the plurality of heat sinks constituting the heat sink module can also be on the inner surface of each tight fitting groove or the side of the leading edge of the notch. Or more than one limiting rib on the two sides, so that the heat pipe and the limiting rib form a relatively tight deformation and lock after the heat absorbing end of the heat pipe is tightly fitted to form a stable joint, thereby ensuring that the heat pipe is in the tight fitting groove. No loose displacement occurs, and the heat pipe has better contact with the heat sink, which can also improve the overall heat dissipation efficiency.

Another object of the present invention is to provide a design of a baseless heat sink, wherein the heat dissipation end of the plurality of heat pipes can be selected to be inserted into the heat sink module, or can be extended to be inserted into one or more other The heat sink module utilizes a combination of multiple sets of heat sink modules to speed up heat dissipation.

Another object of the present invention is to provide a design of a baseless heat sink, wherein the limiting rib of the inner surface of the tight groove of the heat sink includes, but is not limited to, a regular shape or an irregular shape. The shape of the ribs can also be implemented as a regular or irregularly distributed bump shape for forming a stable locking against the deformation of the heat pipe end.

Each of the fins 1 is provided with a plurality of tight fitting grooves 11 at the bottom, and adjacent supporting grooves 11 have a supporting rib 12 smaller than the groove depth (such as the height difference a shown in FIG. 5), and More than one limiting rib 13 (such as the fourth figure) may be disposed on the inner surface of the tight fitting groove 11; the plurality of heat pipes 20 each have a heat absorbing end 21 and a heat radiating end 22, and may have a selected extended shape; By using the above-mentioned heat sink module 10 and the plurality of heat pipes 20, the heat absorbing end 21 of the heat pipe 20 is tightly fitted into the tight groove 11 of the heat sink 1, and then pressed and leveled, so that the plurality of heat pipes 20 are formed without connection. The flatness of the seam state is juxtaposed (as shown in the sixth figure), so that the heat source can directly touch the flattening concentration. The plurality of heat pipes 20 achieve rapid heat dissipation, and because there is no separation distance between the heat pipes 20, the number of heat pipes 20 can be increased, the overall volume and weight of the heat sinks are greatly reduced, and the metal consumables are saved. Cost, and will be more convenient when shipping and shipping.
