The invention discloses a waste gas ejection cooling device with a fan, which comprises an inlet section, a radiator, a contraction section, a volute, the fan, an outlet section and an exhaust section, wherein the inlet section is provided with a heat radiator; the inlet section is connected with the front end of the radiator, the rear end of the radiator is sequentially connected with the contraction end and the volute, the volute is internally provided with a fan, the lower opening of the volute is connected with the outlet section, the volute is provided with an ejector, the exhaust section is located on the left side of the volute and is connected with the volute through the ejector, and the outlet section is internally provided with an outlet shutter. According to the invention, the airflow injection structure is added, so that the flow of the inlet at the air side is increased, and the heat dissipation efficiency is improved; through increasing the air current and drawing and penetrate the structure, make the waste gas outlet heat reduce, strengthen being furnished with high power density engine vehicle disguise under infrared detection. |
