As shown in FIGS. 1 and 2, the design of the “heat exhauster having radial exhaust heat fins” performed by the present invention includes a tubular base 1 and a plurality of exhaust heat fins 2.

The tubular pedestal 1 is provided with a plurality of axially adjacent grooves 11 on the peripheral wall surface of the pedestal, and a first protrusion 12 extending upward on one side of the groove wall of each groove 11.

The plurality of exhaust heat fins 2 are surrounded by the radiation direction and are planted on the tube-shaped pedestal 1, and the bottom ends of the exhaust heat fins 2 are formed with bent portions 21 (as shown in FIG. 3). A combination can be implanted in the groove 11 of the pedestal 1.

When the tubular base 1 and the plurality of exhaust heat fins 2 are used and each exhaust heat fin 2 is combined and implanted in the groove 11 of the base 1, the press mold 3 is pushed down (as shown in FIG. 4). The one protrusion 12 is pressed down, and the bent portion 21 of the exhaust heat fin 2 is applied tightly to form a favorable downward compression coupling. The first protrusion 12 deformed by pressing down both pushes the bent portion 21 together. Since each exhaust heat fin 2 is completely inserted into the bottom of the groove 11 and appears in a firm connection, it becomes the same height when each exhaust heat fin 2 stands upright. There is no solid situation.

As shown in the above embodiment, the exhaust heat fin 2 is a thin metal sheet, and forms a tight bond when deformed in combination with the first protrusion 12 of the tubular pedestal 1. Since the mold heat-dissipating fin 2 has a thinner sheet, the bent portion 21 at the bottom end of the thin-film mold heat-dissipating fin 2 may be provided in a reverse folded shape, whereby the thin-film exhaust heat fin 2 and the first protrusion Increases the strength of the twelve pressing bond. In addition, a slightly blunt reverse folding portion 22 may be attached to the outer dew tip of each thin-walled exhaust heat fin 2, thereby cutting the outer dew tip of the thin-walled heat exhaust fin 2 too sharp. Avoid injury.

As in another embodiment shown in FIGS. 5 to 7, the tubular base 1 of the present invention is provided with a first protrusion 12 on one side of the groove wall of the groove 11, and further advances to the groove wall of the groove 11. On the other side, a second protrusion 13 may be provided that simultaneously extends upward (as shown in FIG. 8 or FIG. 9), so that when the exhaust heat fin 2 is inserted into the groove 11 and pushed down to the press mold 3 The bent portion 21 of the exhaust heat fin 2 forms a tight tight connection with the deformed first protrusion 12, and the second protrusion 13 can provide good contact with the fin of the exhaust heat fin 2 ( Such an abutment contact design ensures that each heat exhaust fin 2 is not misaligned after joining, as shown in the local area of FIG. Keep it up, and don't shake or drop.

According to the above-described embodiment, the exhaust heat fin 2 may be further provided with one set or one or more sets of stop pieces 23 on the upper or lower end surface, and the front and rear adjacent stop pieces 23 are connected to each other and joined together. The exhaust heat fins 2 are more closely connected.

The tubular pedestal 1 of the present invention is shown as a circular tubular shape in the drawings of the embodiments, but in practice the shape or size of the tubular pedestal 1 can be changed as required, for example, rectangular, It can be implemented in a rectangular, oval, rhombus or any other shaped tube, both of which can be implemented. The tubular pedestal 1 is implemented in a tube having a U-shaped cross section (as shown in FIG. 11), and a tightening hole 141 provided for tightening connection of a heating element or an electronic unit is provided in the closing surface 14 of the U-shaped tube. May be. The tubular pedestal 1 may be implemented as a real core tube (as shown in FIG. 12), and of course may be in the form of a hollow tube, and the actual form of the tubular pedestal 1 is not particularly limited.

As shown in FIGS. 13 to 15, it represents a different form of the bent portion 21 at the bottom end of the exhaust heat fin 2, and the bent angle of the bent portion 21 is equal to 90, or may be larger or smaller than 90 degrees. And the groove bottom of each combination groove 11 is also appropriately angled. In addition, the exhaust heat fin 2 of the present invention is not limited to the use of a flaky metal sheet, but as shown in FIGS. 13 to 15, they are formed on the exhaust heat fin 2 using a general metal sheet, It can be planted and bonded to the groove 11 of the pedestal 1 and can form a tight bond when the first projection 12 is deformed or can go further to obtain good abutment support through the second projection 13.

Moreover, all the embodiments of the tubular pedestal 1 described in the present invention, such as the shape, size or tubular shape of the U-shaped, solid core, hollow, etc., can be concretely implemented, and the tubular pedestal 1 is manufactured. Is very suitable for adopting an extrusion technique or an impact stretching technique, and a plurality of grooves 11, first protrusions 12, or second protrusions 13 are formed on the tube wall. Manufacturing is simplified, very suitable for mass production, and effective in reducing costs.

Summarizing the above, the present invention has a novel structure because the structural features of the exhaust heat fin and the tubular pedestal are clearly different from those of the conventional heat exhaust device. Because the structure is very solid, each exhaust heat fin can maintain the same height, there is no phenomenon of angular distortion and inclination, and it has an inventive step It is up to filing a utility model registration application.
