The invention discloses a filtration device for intelligently adjusting the opening rate on the basis of a shape memory polymer and an adjusting method. The device comprises a shell, a filter screen,a support mechanism, a drive and control device, a heating device, an air particle concentration detection device, a temperature detection device and an angle detection device. The device intelligently adjusts the opening rate of the filter screen, and then adjusts the resistance coefficients of the filter screen and the system by utilizing deformation and the memory effect of the shape memory polymer according to real-time detected air particle size data, on the condition that the dust preventing requirements are met, the resistance coefficient is lowered to the maximum extent, and the heat dissipation performance of the system is improved. The device can be directly installed on the equipment, and is mainly applied to equipment working outdoors for a long time or equipment in the workingenvironment with the air particle sizes which are changed obviously.
Description
technical field [0001] The invention belongs to the technical field of filters, and relates to a filter device for intelligently adjusting the porosity based on a shape memory polymer and an adjusting method thereof. Background technique [0002] For mechanical and electronic equipment working outdoors, heat dissipation and dust-proof failure are one of the main causes of equipment failure, and dust-proof and heat dissipation are often difficult to balance. The filter screen is an important part of various mechanical and electronic equipment. The filter screen, fan, radiator, etc. constitute the dustproof and air-cooled heat dissipation system of the equipment. Structural parameters such as the opening ratio of the filter, the type of ventilation holes, and the relative thickness have a great influence on the resistance coefficient. Among them, the smaller the opening ratio, the greater the system resistance coefficient, and the change of the system resistance coefficient wi...
