Description

Technical Field

[0001] The utility model relates to a heat dissipation element combination structure, in particular to a heat dissipation element combination structure which increases the combination efficiency and the degree of combination between the heat dissipation element and a base. Background Art

[0002] Conventional heat sinks have an integrated structure formed by extrusion, casting, or machining. There are also modular heat sinks that combine a plurality of heat sink fins with a thermally conductive base. The modular heat sink is mainly combined by welding the heat sink fins to the thermally conductive base and then forming grooves on the surface of the thermally conductive base for the heat sink fins to fit tightly together, thereby combining the two.

[0003] However, since the thickness of the heat sink fins varies and the spacing between the multiple heat sink fins is too narrow, interference is easily generated during construction when they are plugged into the thermal base, making it impossible to smoothly combine the multiple heat sink fins with the thermal base, causing manufacturing difficulties. Therefore, how to improve the interference problem when combining the heat sink fins and the thermal base is currently the most important issue. Utility Model Content

[0004] Therefore, in order to effectively solve the above-mentioned problems, the main purpose of the present invention is to provide a heat dissipation element assembly structure that improves the interference generated when the heat dissipation fins are combined with the heat conductive base.

[0005] To achieve the above-mentioned objectives, the present invention provides a heat dissipation element assembly structure, characterized by comprising:

[0006] A base having a bonding surface and a heating surface, wherein the bonding surface has a plurality of grooves;

[0007] The plurality of heat dissipation fins comprises a main body and a connecting portion. A difference section is provided between the main body and the connecting portion so that the main body and the connecting portion are connected in a staggered state.

[0008] The heat dissipation element combination structure, wherein: the heat dissipation fin body has an airtight chamber inside.

[0009] The heat dissipation element combination structure, wherein: the heat dissipation fins are made of metal or non-metal, the metal is any one of gold, silver, copper, stainless steel, aluminum, copper alloy, aluminum alloy, titanium, and titanium alloy, and the non-metal is any one of plastic, graphite, and ceramic.

[0010] The heat dissipation element assembly structure is characterized in that the plurality of heat dissipation fins are composed of a first thin plate and a second thin plate that are bonded to each other, and the plurality of first thin plates and the second thin plates jointly define an airtight chamber.

[0011] The heat dissipation element assembly structure, wherein: the first thin plate has a first groove, the second thin plate has a second groove, and the first groove and the second groove jointly define the aforementioned airtight chamber.

[0012] The heat dissipation element combination structure, wherein: the inner surface of the airtight chamber has a capillary structure layer and is filled with working liquid.

[0013] The advantage of the present invention is that a difference section is provided between the main body and the connecting portion, so that the main body and the connecting portion are in a staggered or asymmetrical state. When the plurality of heat sink fins are combined with the base, the design of the difference section of the heat sink fin section can improve the disadvantage of mutual interference between the heat sink fins during installation.

DETAILED DESCRIPTION

[0017] The above-mentioned objectives and structural and functional characteristics of the present invention will be described with reference to the preferred embodiments shown in the accompanying drawings.

[0018] See also Figure 1 、 Figure 2 , are respectively three-dimensional exploded and assembled diagrams of the first embodiment of the heat dissipation element combination structure of the present invention. As shown in the figure, the present invention provides a heat dissipation element combination structure, comprising: a base 1, a plurality of heat dissipation fins 2;

[0019] The base 1 has a bonding surface 11 and a heating surface 12 in contact with the heat source, and the bonding surface 11 has a plurality of grooves 111; the plurality of heat dissipating fins 2 has a body, which can be composed of a first thin sheet 21 and a second thin sheet 22 that are correspondingly bonded, and the plurality of first and second thin sheets 21, 22 jointly define an airtight chamber 23, and the plurality of heat dissipating fins 2 have a bonding portion 24 at one end of the body, and the plurality of heat dissipating fins 2 are embedded in the groove 111 through the bonding portion 24, so that the plurality of heat dissipating fins are combined with the base 1 Fixed, the utility model is that there is a step section 25 (configured by bending or tilting, etc.) between the main body and the joint part of the plurality of heat dissipating fins 2 (between the joint part 24 and the main body 23 with the airtight chamber). The step section 25 makes the main body with the airtight chamber and the joint part present in a staggered or asymmetrical state, and the step section 25 can prevent the plurality of heat dissipating fins 2 from interfering with each other when the plurality of heat dissipating fins 2 are combined with the base 1. In addition, the inner surface of the airtight chamber 23 has a capillary structure layer 26 and is filled with a working liquid 27.

[0020] The first thin plate 21 has a first groove 211, and the second thin plate 22 has a second groove 221. When the first and second thin plates 211 and 221 are correspondingly covered, the first and second grooves 211 and 221 jointly define the aforementioned airtight chamber 23, thereby forming a heat dissipation fin 2 with an airtight chamber 23, further significantly improving the overall heat dissipation performance through the heat conduction method of two-phase flow gas-liquid change.

[0021] The heat sink fins 2 are made of metal or non-metal. The metal is any one of gold, silver, copper, stainless steel, aluminum, copper alloy, aluminum alloy, titanium, and titanium alloy. The non-metal is any one of plastic, graphite, and ceramic.

[0022] The fins in the present invention are primarily comprised of two independent, pre-formed sheets 21 and 22 having a plurality of concave and convex portions formed by stamping or other mechanical processing. The concave and convex portions collectively define an airtight chamber 23. The first and second sheets 21 and 22 are stacked and sealed to form the heat dissipation fins 2. Furthermore, because the outwardly protruding portions of the first and second sheets 21 and 22 of two adjacent heat dissipation fins 2 would interfere with each other, the step section 25 prevents the plurality of heat dissipation fins 2 from interfering with each other when they are combined with the base 1.

[0023] The present invention mainly provides a structure of a heat sink fin with a cavity and a heat conductive base, and improves the problem of interference between the heat sink fins by designing the step section 25 of the heat sink fin to be tilted or bent or by setting the joint between the heat conductive base and the heat sink fin to be tilted.
