The air 50 jetted from the air collides with the heat dissipation plate 20 and exhausts air 6
It becomes 0 and is discharged upward through the gap between the heat dissipation plate 20 and the air chamber 40.
The air volume of 0 increases and the air pressure increases. Since the cooling efficiency is proportional to the difference between the air pressure inside the air chamber 40 and the air pressure in the exhaust system, it is necessary to provide a gap between the heat dissipation plate 20 and the air chamber 40 in order to avoid a decrease in cooling efficiency. There is an increase in occupied volume.

回避できる。Referring to FIG. 1 showing a first embodiment, a cooling device is integrally provided on a wall portion 4a of an air chamber 4 facing a heat radiating plate 2 which receives heat from a heating element 1 and is introduced from the air chamber 4. A plurality of nozzles 3 for ejecting the generated air 5 to the heat dissipation plate 2 are provided. The distance between the tip of these nozzles 3 and the heat dissipation plate 2 is the same, and the air chamber 4
The wall portion 4a of the is inclined upward so as to increase the facing interval with the heat dissipation plate 2. In this structure, the distance between the radiator plate 2 and the wall portion 4a of the air chamber 4 is equal to the exhaust air 6
As a result, the air flow rate is set to be larger toward the upper side of the exhaust section where the air volume increases, so that it is possible to avoid an increase in the wind speed of the exhausted air 6 above the exhaust section.
