Description

Technical Field

[0001] The invention relates to a heat dissipation element combination structure, and more particularly to a heat dissipation element combination structure which increases the combination efficiency and the combination degree of 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 combined heat sinks that are composed of a plurality of heat sink fins and a thermally conductive base. The combined heat sink is mainly combined by combining the heat sink fins with the thermally conductive base and then welding or opening grooves on the surface of the thermally conductive base for the heat sink fins to fit tightly together.

[0003] However, since the thickness of the heat sink fins is different 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, and the multiple heat sink fins cannot be smoothly combined with the thermal base, causing manufacturing problems. Therefore, how to improve the interference problem when the heat sink fins are combined with the thermal base is the most important problem at present. Summary of the invention

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

[0005] To achieve the above-mentioned purpose, the present invention provides a heat dissipation component assembly structure, characterized in that it comprises:

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

[0007] A plurality of heat dissipation fins are provided with 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 dislocated state.

[0008] The heat dissipation element combination structure, wherein: the body of the heat dissipation fin 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, wherein: the plurality of heat dissipation fins are composed of a first thin sheet body and a second thin sheet body that are correspondingly bonded, and the plurality of first thin sheets and the second thin sheets jointly define an airtight chamber.

[0011] The heat dissipation element assembly structure, wherein: the first thin sheet body has a first groove, the second thin sheet body has a second groove, the first groove and the second groove together 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 joint portion, so that the main body and the joint portion are in a misaligned or asymmetrical state, so that 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 objects and the structural and functional characteristics of the present invention will be described based on the preferred embodiments shown in the accompanying drawings.

[0018] See also Figure 1 , Figure 2 , respectively, are 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 dissipation fins 2 have a body, which can be composed of a first thin sheet body 21 and a second thin sheet body 22 that are correspondingly attached to each other, and the plurality of first and second thin sheets 21, 22 jointly define an airtight chamber 23, and the plurality of heat dissipation fins 2 have a bonding portion 24 at one end of the body, and the plurality of heat dissipation fins 2 are embedded in the groove 111 through the bonding portion 24, so that the plurality of heat dissipation fins are bonded to the base 1. The present invention is that a step section 25 (configured by bending or tilting, etc.) is provided between the main body and the joint portion of the plurality of heat dissipating fins 2 (between the joint portion 24 and the main body 23 with the airtight chamber), and the step section 25 is used to make the main body with the airtight chamber and the joint portion present a misaligned 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, and 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 sheet body 21 has a first groove 211, and the second sheet body 22 has a second groove 221. When the first and second sheet bodies 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, and further greatly improving the overall heat dissipation efficiency 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 mainly composed of two independent first and second thin sheet bodies 21 and 22 which are pre-formed with a plurality of concave and convex parts by stamping or other mechanical processing, and the concave and convex parts jointly define an airtight chamber 23. The first and second thin sheet bodies 21 and 22 are stacked and sealed to form the heat dissipation fins 2. Because the outwardly protruding parts of the plurality of first and second thin sheet bodies 21 and 22 of two adjacent heat dissipation fins 2 will interfere with each other, the step section 25 can prevent 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 heat sink fin's step section 25 to be tilted or bent or by tilting the joint between the heat conductive base and the heat sink fin.
