Description

[Detailed Description of the Invention] The present invention relates to a cooling air path for a portable compressor whose power source is a motor equipped with a self-cooling fan.

In a conventional compressor equipped with a large-capacity tank, the temperature rise in the tank due to compressed air is cooled by natural heat radiation on the outer surface of the tank, so it was sufficient to mainly cool the compression section with a fan.

However, in a compact portable compressor with a small capacity tank, the temperature of the tank increases significantly, making it necessary to forcibly cool the tank.

The purpose of this proposal is to efficiently cool the tank of a portable compressor.

In other words, this proposal focuses on the fact that when a hole is made in the outer wall of a cylindrical air passage and air is allowed to flow into the cylinder, outside air is sucked in through the hole in the outer wall, and this is applied to the air passage for cooling the tank. The wind path was devised.

The present invention will be explained below with reference to illustrated embodiments.

In the figure, 1 is a motor, 2 is a compression section, and 3 is a tank, and the motor 1 has a self-cooling fan 4 and an air outlet 5.
has. an upper partition plate 8 having an upper end 6 and an upper hole 7 along the outer surface of the tank with a gap from the tank 3;
A lower partition plate 10 having a pilot hole 9 is arranged above and below the space connecting the air outlet 5 and the tank 3 with an upper gap 11 and a lower gap 12 between the air passage 13 and the tank 3.
form. As a result, the air generated by the self-cooling fan 4 is released from the air outlet 5, passes through the air path 13, flows through the upper hole and the lower hole 9 while sucking outside air, and flows through the upper gap 11 and the lower gap. 12
More leakage.

As described above, according to the present invention, the tank is cooled by the wind mixed with cold outside air, and since the wind flows along the outer circumference of the tank, the tank is efficiently cooled.
