| description | ObjectivesAiming at the problems of the long response time and excessive time consumption of infrared cooling equipment, an optimization study is carried out.MethodsA special cooling method based on the combined effects of absorption, scattering of water mist particles and cooling of water film is proposed to attenuate the infrared radiation intensity of the target object and improve the response speed of the infrared cooling system. The infrared cooling characteristics of the composite nozzle and water film nozzle at different pressures are analyzed through comparative design experiments.ResultsThe test results show that under water supply pressures of 0.3, 0.5 and 0.8 MPa, the infrared cooling time of the composite nozzle is reduced by 27.9%, 47.3% and 46.2% respectively compared with that of the water film nozzle. At the moment the water mist is sprayed, the temperatures measured by the infrared thermal imaging camera are 8.62, 11.13 and 11.09 ℃ lower than the actual temperature of the target.ConclusionsThe test results show that the swirling atomizer composite nozzle can effectively control the infrared cooling time of the target object. |
