The trim ring fixes the position of the first radiating fin, the second radiating fin and heat sink body on top and bottom respectively
Put.
Further, tell that the first radiating fin and the second radiating fin are aluminium flake, first radiating fin and second dissipate
Some heat emission holes are offered on hot fin.
Further, first radiating fin and the second radiating fin are gradual change shape, the centre of first radiating fin
Cross section is trapezoidal, and the end face of first radiating fin is rectangle.
Further, the raised surface is curved surface, and the raised surface projection is trapezoidal, and the recess inner surface is
Curved surface.
Further, it is provided with tapped through hole on the trim ring, the projection on the heat sink body is on heat sink body end face
Provided with internal thread, the trim ring covers the first radiating fin and second radiating fin on heat sink body end face.
By adopting the above-described technical solution, the utility model has the following advantages：Pass through heat sink body fixed structure

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figures 1 to 5, the utility model discloses a kind of simply-assembled phase-change heat sink, including heat sink body
1st, the first radiating fin 2, the second radiating fin 3 and trim ring 4, the heat sink body 1 offer through hole 5, on the heat sink body 5
Several trapezoidal grooves 6 are offered, one end of first radiating fin 2 is trapezoidal, described first radiating fin, 2 trapezoidal one end
Cooperate and install with trapezoidal groove 6；
Projection 10 is formed between several described trapezoidal grooves 6, described one end of second radiating fin 3 is provided with recess 7, described
Second radiating fin 3 cooperates with projection 10 to be installed；Projection 10 is consistent with the shape of recess 7, and class is trapezoidal, and outer edge surface is curved surface.
The trim ring 4 fixes the first radiating fin 2, the second radiating fin 3 and heat sink body 1 on top and bottom respectively
Position.
Tell that the first radiating fin 2 and the second radiating fin 3 are aluminium flake, the radiating fin of the first radiating fin 2 and second
3 heat emission holes 8 are offered on piece 3.Can according to heat emission hole 8 is actually opened up, ensure to increase based on agent structure radiating fin with
The surface area of air contact.
The radiating fin 3 of first radiating fin 2 and second is gradual change shape, and the centre of first radiating fin 2 is transversal
