Abstract

The present disclosure relates to a heat-radiating mechanism for an antenna device, and particularly, includes: a plurality of communication elements generating predetermined heat upon electrical operation, a heat-radiating combined case having the plurality of communication elements accommodated in one surface thereof and a plurality of heat-radiating ribs integrally formed on the other surface thereof, and an antenna board mounted with the plurality of communication elements on one surface of the heat-radiating combined case, in which the plurality of heat-radiating ribs are formed such that the rising airflow formed by being heat-radiated from the relatively lower portion of the heat-radiating combined case is exhausted to be inclined upward to the left and right outsides of the heat-radiating combined case in the width direction from the relatively upper position, thereby improving the heat-radiating performance of the antenna device.

First claim

The invention claimed is:

1. A heat-radiating mechanism for the antenna device comprising:
a plurality of communication elements generating predetermined heat upon electrical operation;
a heat-radiating combined case having the plurality of communication elements accommodated in one surface thereof and a plurality of heat-radiating ribs integrally formed on the other surface thereof, and formed to be vertically and longitudinally elongated; and
an antenna board mounted with the plurality of communication elements on one surface of the heat-radiating combined case,
wherein the plurality of heat-radiating ribs are formed such that the rising airflow formed by being heat-radiated from the relatively lower portion of the heat-radiating combined case is exhausted to be inclined upward to the left and right outsides of the heat-radiating combined case in the width direction from the relatively upper position.

2. The heat-radiating mechanism for the antenna device of claim 1 ,
wherein the plurality of heat-radiating ribs comprise:
a plurality of extrusion heat-radiating ribs disposed in multiple stages to be vertically spaced apart from each other at a predetermined distance such that an empty space is formed in each of one side and the other side of the heat-radiating combined case in the width direction; and
a plurality of casting heat-radiating ribs produced by a die casting method to be coupled to the empty space between the plurality of extrusion heat-radiating ribs, and having a plurality of inclined ribs disposed to be inclined upward to the left and right outsides of the heat-radiating combined case in the width direction, respectively, with respect to the center.

3. The heat-radiating mechanism for the antenna device of claim 2 ,
wherein the plurality of extrusion heat-radiating ribs of the plurality of heat-radiating ribs are disposed to be spaced apart from each other at a first separation distance in the width direction of the heat-radiating combined case, and
wherein the plurality of casting heat-radiating ribs are disposed to be spaced apart from each other at a second separation distance to which each lower end of the plurality of casting heat-radiating ribs is connected to each front end of the plurality of extrusion heat-radiating ribs.

4. The heat-radiating mechanism for the antenna device of claim 3 ,
wherein the plurality of casting heat-radiating ribs of the plurality of heat-radiating ribs are extensively formed such that each upper end is matched to one end and the other end of the heat-radiating combined case in the width direction.

5. The heat-radiating mechanism for the antenna device of claim 4 ,
wherein at least one of the plurality of casting heat-radiating ribs is disposed to connect the lower end of each rib of the plurality of extrusion heat-radiating ribs disposed on the upper portions thereof.

6. The heat-radiating mechanism for the antenna device of claim 2 ,
wherein the empty space formed between the plurality of extrusion heat-radiating ribs is formed in a triangular shape.

7. The heat-radiating mechanism for the antenna device of claim 6 ,
wherein the plurality of casting heat-radiating ribs comprise:
a first rib group filled in one side empty space formed in the triangular shape on one side of the heat-radiating combined case in the width direction; and
a second rib group filled in the other side empty space formed in the triangular shape on the other side of the heat-radiating combined case in the width direction, and
wherein the first rib group and the second rib group are integrally molded by a die casting.

8. The heat-radiating mechanism for the antenna device of claim 2 ,
wherein a shape of the lower end formed by each rib of the plurality of extrusion heat-radiating ribs is provided in a ‘V’ shape, and
wherein two ribs of the plurality of casting heat-radiating ribs disposed on the uppermost end thereof are provided in a ‘V’ shape to connect each lower end of the plurality of extrusion heat-radiating ribs.
