Abstract: A cooling device for electronic components has a main body, a motor, an adaptor tube, a shaft, a valve assembly, a reservoir, and a delivery tube. The motor is mounted in the main body. The adaptor tube is mounted between the main body and the reservoir and is gradually smaller in diameter from the main body to the reservoir. The shaft connects to the motor, extends into the adaptor tube and has multiple fan blades corresponding to the inside diameter of the adaptor tube. The fan blades blow the air through the adaptor tube into the reservoir to pressurize the air. The pressurized air flows through the delivery tube to contact the electronic component and equalizes to correspond to the atmosphere. The equalizing process of the pressurized air absorbs heat from the electronic component as it expands to cool the electronic component.
