Abstract

The invention relates to a steam quantity precisely controlled steam generating device for an automobile test. The steam generating device comprises a centrifugal fan, a diffusion chamber, a sealing cover, an insulation water storage tank and a PTC (Positive Temperature Coefficient) heater, wherein the centrifugal fan is provided with an air inlet and an air outlet; the diffusion chamber is connected with the air outlet of the centrifugal fan; steam exhaust holes are uniformly distributed at the lower end of the diffusion chamber; a water injection port is formed in the top of the insulation water storage tank; the sealing cover is screwed on the water injection port of the insulation water storage tank; the bottom of the diffusion chamber is connected with the sealing cover; the PTC heater is attached to the inner side of an inner container of the insulation water storage tank; and a power supply wire is led out of the side surface of the bottom of the insulation water storage tank. The principle of the steam generating device is simple and easy to understand, and the steam generating device is convenient to operate, low in cost, and good in steam generating effect, and is very applicable to defrosting and demisting tests of an automobile windscreen.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a steam generating device for artificially generating fog on an automobile windshield. Background technique [0002] The defogging and defrosting performance of the vehicle directly affects whether the driver can drive the vehicle normally and safely in bad weather, as well as the safety and comfort of the occupants. When the outside temperature is lower than the temperature inside the car, and the air circulation in the car is not smooth, the humidity of the gas exhaled by the occupants is high. When encountering a colder windshield, it will condense into small water droplets and adhere to the inner surface of the windshield, making the glass The transparency of the car is severely reduced, and it is not easy to remove, so the driver's line of sight is also damaged. [0003] In order to test the defogging and defrosting performance of the vehicle, an atomizing device...
