[0035] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0036] Please refer to Figures 1 to 6 The present invention relates to a combined heat dissipation device, including a heat dissipation device body, wherein the heat dissipation device body includes a plurality of spacer blocks 1 and a plurality of heat dissipation fin units 2.

[0037] The left and right sides of the spacer block 1 are respectively provided with a first plane 11 and a second plane 12 that are parallel to each other;

[0038] The first plane 11 is provided with a straight protrusion 13;

[0039] The second plane 12 is provided with a straight groove 14 that matches the straight protrusion 13, and the straight protrusion 13 is parallel to the straight groove 14;

[0040] The heat sink unit 2 is provided with a strip-shaped hole 21 that matches the straight protrusion 13; the sum of the thickness of the heat sink and the depth of the straight groove 14 is equal to the protrusion distance of the straight protrusion 13.

[0041] The heat sink unit 2 is connected to the straight protrusion 13 through the strip hole 21. Two adjacent spacers 1 are connected to each other through the cooperation of the straight protrusion 13 and the straight groove 14, so that the heat sink is clamped between two adjacent spacers 1. Each heat sink unit 2 and spacer 1 is arranged in sequence at intervals, so that each heat sink unit 2 is distributed at equal intervals.

[0042] In the above embodiments, when it is necessary to assemble the heat dissipation device body, it is only necessary to fit the heat sink unit 2 through the strip hole 21 onto the straight protrusion 13 of the spacer block 1, and then connect the spacer blocks 1 with each other through the straight protrusion 13 and the straight groove 14, and separate two adjacent heat sink units 2 with the spacer blocks 1; thus, multiple heat sink units 2 can be arranged at equal intervals; after the left and right sides of the heat dissipation device body are simply clamped and fixed, the heat dissipation device can be formed. The advantage of this structure is that the number of spacer blocks 1 and heat sink units 2 can be flexibly selected according to the width of the heat-generating equipment, so that the heat dissipation device can be used for different types and models of heat-generating equipment through detachable and combinable means.

[0043] As an optional implementation, the straight groove 14 is a dovetail groove, and the straight protrusion 13 includes a first limiting part 131 and a second limiting part 132 arranged from the inside to the outside. The cross-section of the first limiting part 131 is rectangular, and the cross-section of the second limiting part 132 is a trapezoid that matches the dovetail groove.

[0044] In the above embodiments, the structure of the dovetail groove and the second limiting part 132 between two adjacent spacer blocks 1 makes the overall structure of the heat dissipation device body more stable and prevents it from loosening. The first limiting part 131 is used to connect with the strip hole 21 of the heat sink unit 2 so that the heat sink unit 2 is clamped between two adjacent spacer blocks 1.

[0045] In the above embodiments, it should be noted that the thickness of the first limiting part 131 is the same as the thickness of the heat sink unit 2; the width of the first limiting part 131 is smaller than the width of the strip hole 21, so that the straight protrusion 13 can pass smoothly through the strip hole 21.

[0046] As an optional implementation, the spacer block 1 is provided with a plurality of through holes 15 with parallel axes, the axes of the through holes 15 being parallel to the straight protrusions 13.

[0047] As an optional implementation, the heat dissipation device further includes multiple heat dissipation pipes, which pass through the through hole 15.

[0048] In the above embodiments, the through hole 15 is used to insert a heat dissipation pipe, which can be a copper pipe. The heating device can be thermally connected to the spacer block 1 through the copper pipe, so that the heat generated by the heating device can be conducted to the spacer block 1 through the copper pipe, and then to the heat sink unit 2, thereby dissipating heat through the surface of the heat sink unit 2.

[0049] As an optional implementation, two adjacent through holes 15 are interconnected by a slot 16.

[0050] In the above embodiments, two adjacent through holes 15 are interconnected by a slot 16. This structure allows the spacer block 1 to undergo a certain elastic deformation when the copper tube passes through the through hole 15, so that the through hole 15 is appropriately opened, and the copper tube can be inserted into the through hole 15 with an interference fit, so that the heat of the copper tube can be fully conducted to the spacer block 1.

[0051] Preferably, small holes can be provided above and below the through hole 15, and the small holes and the through hole 15 are also connected by a slot 16, so as to ensure that the through hole 15 located at the top and bottom has a certain elastic potential energy and can be connected with the through hole 15 by interference fit.

[0052] As an optional implementation, the spacer block 1 is in the shape of a parallelogram.

[0053] As an optional implementation, each of the spacer blocks 1 has two or more straight protrusions 13 and two or more straight grooves 14. Preferably, there are two grooves, which can improve the structural stability of the heat dissipation device body.

[0054] As an optional implementation, the heat dissipation device further includes side fixing plates 3 and connecting rods 4. The two side fixing plates 3 are symmetrically pressed against both sides of the heat dissipation device body, and the two side fixing plates 3 are connected to each other by two or more connecting rods 4.

[0055] In the above embodiments, refer to Figure 6 The two ends of the connecting rod 4 can be connected to the two side fixing plates 3 by screws, so that the side fixing plates 3 can be stably connected to both sides of the heat dissipation device body, thereby improving the stability of the heat dissipation device body.

[0056] As an optional implementation, the heat dissipation device further includes a limiting rod 5. The heat sink unit 2 is provided with a limiting hole 22. The limiting rod 5 passes through the limiting hole 22 of each heat sink unit 2 in sequence. The two ends of the limiting rod 5 are respectively fixedly connected to the two side fixing plates 3.

[0057] In the above embodiments, the limiting rod 5 passes through the limiting hole 22 of each heat sink unit 2 and is fixedly connected to the side fixing plate 3, which can assist in limiting each heat sink unit 2 and improve structural stability.

[0058] As an optional implementation, both the heat sink unit 2 and the spacer block 1 are made of thermally conductive metals, such as aluminum alloy.
