[0039] Please refer to Figures 1 to 3 , in which Figure 1 is a three-dimensional schematic view of a composite heat dissipation component shown according to an embodiment of the present invention, Figure 2 is Figure 1 a disassembled schematic view of the composite heat dissipation component of Figure 3 is Figure 2 a partially enlarged disassembled schematic view of the composite heat dissipation component of

[0040] The composite heat dissipation component 1 disclosed in this embodiment includes an air-cooled radiator 11 and a liquid-cooled radiator 12.

[0041] The air-cooled radiator 11 may include a heat-conducting base 111, a plurality of heat-dissipating tubes 112, and a plurality of fans 113. The heat-conducting base 111 is used to thermally couple to a heat source (not shown separately) such as a central processing unit (CPU) to absorb the heat generated during the operation of the heat source. The heat-dissipating tubes 112 may penetrate the heat-conducting base 111 and extend in a direction away from the heat-conducting base 111 to transfer the heat absorbed by the heat-conducting base 111 to one end away from the heat-conducting base 111. The fans 113 may be disposed at one end of the heat-dissipating tubes 112 away from the heat-conducting base 111 to provide an air flow to the heat-dissipating tubes 112 to carry away the transferred heat.

[0042] The liquid-cooled radiator 12 may include a liquid-cooling head 121, a liquid-cooling radiator 122, and a plurality of fans 123. The liquid-cooling head 121 is thermally coupled to the heat-conducting base 111 to assist in absorbing part of the heat absorbed by the heat-conducting base 111. The liquid-cooling radiator 122 may be connected to the liquid-cooling head 121 to form a cooling cycle, so as to use the working fluid (not shown separately) in the cooling cycle to carry away the heat absorbed by the liquid-cooling head 121 from the liquid-cooling head 121. The fans 123 may be disposed on the liquid-cooling radiator 122 to provide an air flow to the liquid-cooling radiator 122 to carry away the heat transferred to the liquid-cooling radiator 122.

[0043] Please also refer to Figure 4 which is Figure 1 a partially enlarged cross-sectional schematic view of the composite heat dissipation assembly. As Figure 4 shown, the liquid-cooled radiator 12 may further include a plurality of heat dissipation fins 124. The heat dissipation fins 124 may be disposed inside the liquid-cooling head 121 to quickly transfer the heat absorbed by the liquid-cooling head 121 to the liquid-cooling radiator 122 through the heat dissipation fins 124 by the working fluid. Since the sizes of these heat dissipation fins 124 are very small, simply welding the liquid-cooling head 121 to the heat-conducting base 111 easily causes the heat dissipation fins 124 inside the liquid-cooling head 121 to deform due to the high welding temperature, thereby affecting the heat transfer inside the liquid-cooling head 121. Therefore, the combination method of the air-cooled radiator 11 and the liquid-cooled radiator 12 will be introduced below.

[0044] The heat-conducting base 111 has a first engaging portion 111a. As Figure 3 and Figure 4 shown, the first engaging portion 111a may be a groove in the shape of a dovetail groove (which may also be called a dovetail mortise, a swallowtail groove, or a swallowtail mortise). The liquid-cooling head 121 has a second engaging portion 121a. As Figure 3 and Figure 4As shown, the second engaging portion 121a can be a protrusion in the shape of a dovetail (also known as a swallowtail). The second engaging portion 121a is structurally engaged with the first engaging portion 111a in a concave-convex manner, so that the second engaging portion 121a is detachably engaged with the first engaging portion 111a along a moving direction D1. Moreover, through the dovetail groove-shaped recess and the dovetail-shaped protrusion, the movement of the second engaging portion 121a relative to the first engaging portion 111a in two directions perpendicular to the moving direction D1 can be restricted.

[0045] The composite heat dissipation assembly 1 can further include a limiting member 13. The limiting member 13 can include two plate bodies 131 and a plurality of screws 132. The plate bodies 131 are respectively attached to opposite sides of the heat conducting base 111 by screws 132 in the moving direction D1, and the plate bodies 131 stop the second engaging portion 121a in the moving direction D1 to restrict the relative movement between the heat conducting base 111 and the liquid cooling head 121 along the moving direction D1.

[0046] Through the concave-convex engagement in structure between the dovetail groove-shaped first engaging portion 111a and the dovetail-shaped second engaging portion 121a, and the arrangement of the limiting member 13, the air-cooled radiator 11 can be fixed to the liquid-cooled radiator 12, which is conducive to the heat exchange between the heat conducting base 111 and the liquid cooling head 121, and can avoid the deformation of the heat sink 124 caused by improper engagement methods such as welding. Thereby, the composite heat dissipation assembly 1 can retain the energy-saving advantages of the air-cooled radiator 11 and the good heat dissipation efficiency advantages of the liquid-cooled radiator 12, and there will be no problems of poor heat dissipation efficiency or excessive energy consumption due to only adopting a single air-cooling system or liquid-cooling system.

[0047] Please note that the dovetail groove-shaped first engaging portion 111a and the dovetail-shaped second engaging portion 121a above are not used to limit the present invention. Please refer to Figure 5 , which is a partially enlarged cross-sectional schematic view of the composite heat dissipation assembly shown according to another embodiment of the present invention. The composite heat dissipation assembly 2 disclosed in this embodiment is similar to the composite heat dissipation assembly 1 of the previous embodiment, so only the differences and necessary features will be described below.

[0048] In this embodiment, the composite heat dissipation assembly 2 includes an air-cooled radiator 21, a liquid-cooled radiator 22, and a limiting member 23. The first engaging portion 211a of the air-cooled radiator 21 can be a straight groove, and the second engaging portion 221a of the liquid-cooled radiator 22 can be a straight protrusion. The second engaging portion 221a is structurally engaged with the first engaging portion 211a in a concave-convex manner. The limiting member 23 includes a plurality of screws 232. The screws 232 pass through the first engaging portion 211a and are attached to the second engaging portion 221a to restrict the relative movement between the heat conducting base 211 and the liquid cooling head 221. Thereby, the air-cooled radiator 21 can also be fixed to the liquid-cooled radiator 22.

[0049] Note that the first engaging portion 211a of the above linear groove and the second engaging portion 221a of the linear protrusion are not used to limit the present invention. In some embodiments, the first engaging portion and the second engaging portion may also be in a cross shape or an inverted T shape, etc., with a concave-convex mating structure.

[0050] For the composite heat dissipation assembly according to the above embodiment, through the concave-convex mating of the first engaging portion and the second engaging portion in terms of structure and the setting of the limiting member, the air-cooled radiator can be fixed to the liquid-cooled radiator, which is beneficial to the heat exchange between the heat conduction base and the liquid-cooled head, and can avoid the deformation of the heat sink caused by improper bonding methods such as welding. Thereby, the composite heat dissipation assembly can retain the advantages of energy saving of the air-cooled radiator and the good heat dissipation efficiency of the liquid-cooled radiator, and there will be no problems of poor heat dissipation efficiency or excessive energy consumption due to only adopting a single air-cooling system or liquid-cooling system.

[0051] In the present invention, the so-called thermal coupling may refer to two elements achieving heat exchange through ways such as thermal contact, heat convection, or thermal radiation.

[0052] Although the present invention is disclosed as the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the relevant art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be subject to the scope defined by the claims.
