Further, a sealed circuit is formed in the plurality of through-holes and the plurality of lateral passages, at least one hot piece is welded to the outer edge surface of the annular body, and the cooling liquid is caused to flow in the sealed circuit. A heat dissipation effect is achieved by the heat dissipation piece.

  The above-mentioned device is intended to improve the heat dissipation effect. However, since at least one heat piece and the annular body are molded and manufactured separately, the heat dissipation piece is welded to the outer edge surface of the annular body, so the production process is very This is complicated and labor intensive, and the manufacturing cost is high, and the flow direction of the cooling liquid in the sealed circuit is limited to a fixed path, so that the heat radiation efficiency is limited, and the efficiency is not preferable.

  First, as shown in FIGS. 1, 2, and 3, the radiator of the present invention includes a heat radiating component 10, an upper lid 20, and a lower lid 30.

  The heat radiation component 10 includes an annular peripheral wall 11 and a plurality of heat radiation pieces 12. The annular peripheral wall 11 penetrates the upper end surface 13, the lower end surface 14 installed in the direction opposite to the upper end surface 13, the outer peripheral surface 15 connected to the upper end surface 13 and the lower end surface 14, and the upper end surface 13 through the lower end surface 14. A plurality of through holes 16. The plurality of heat radiating pieces 12 are integrally formed on the outer peripheral surface 15 of the annular peripheral wall 11, are extended outward, and are arranged at intervals.

  The upper lid 20 is fixed to the upper end surface 13 of the heat dissipation component 10, and an upper annular passage 21 connected to the plurality of through holes 16 is formed between the upper lid 20 and the upper end surface 13.

  The lower lid 30 is fixed to the lower end surface 14 of the heat dissipation component 10, and a lower annular passage 31 connected to the plurality of through holes 16 is formed between the lower lid 30 and the lower end surface 14.

  As shown in FIGS. 4 and 5, after fixing the heat radiating component 10, the upper lid 20, and the lower lid 30, the upper annular passage 21, the through hole 16, and the lower annular passage 31 together form a sealed area 40. The sealed area 40 is for injecting a cooling liquid for heat dissipation (for example, water, refrigerant, not shown), and the cooling liquid arbitrarily flows in the sealed area 40. The radiator is attached on the heat generating member 50. When the heat generating member 50 is activated to generate heat, the heat is guided by the plurality of air passages formed by the plurality of heat dissipating pieces 12 arranged at intervals. Since the cooling liquid flows arbitrarily without being limited in the sealed area 40 and quickly guides and releases the heat quantity of the heat generating member 50, the effect of the entire heat dissipation can be enhanced.

  FIG. 5 shows a radiator of a radiator mounted on the heat generating member 50 in a vertical manner.

The plurality of through holes 16 are arranged so as to form a single ring, which is also used for explaining one embodiment of the present invention, and the present invention is limited by this. First, the plurality of through holes 16 are arranged in at least two rings. Similarly to the above, the radiator mounted on the heat generating member 50 shown in FIGS. 5 and 6 is only used for explaining one embodiment of the present invention, and does not limit the present invention. At least two radiators can be attached (see FIG. 7).

In summary, the present invention has the following inventive step.
