Microfilter membrane module for drying, cooling and defogging

Abstract

The invention discloses a microfilter membrane module for drying, cooling and defogging. The microfilter membrane module comprises a cavity, a drying agent mixture and a supporting piece, wherein thecavity is internally filled with the drying agent mixture; the supporting piece is used for separating the drying agent mixture; a micro-nanoporous film is arranged on a channel thorough which the airinside and outside the cavity can circulate, so that a microfiltration drying channel for the two-way reversible absorption and desorption of the moisture water molecules can be formed in the cavity.Therefore, the microfilter membrane module has a bidirectional regulation and control capability; the components are small in sizes, do not occupy the effective space of a shell, and only need to beassembled on a hole cover of the housing; the microfilter membrane module prevents the fogging and condensation of the interiors of electrical and electronic equipment, vehicle headlights and the like, and reduces the temperature inside the shell, so that the plastic material does not deform and age, and performance of the plastic material is effectively and reliably exerted; the microfilter membrane module can be used for a long time without maintenance during a life cycle, thus greatly lowering the later cost of a consumer.

Description

technical field [0001] The invention relates to a micro-filter membrane assembly for drying, cooling and defogging. Background technique [0002] The control of moisture in the product shell, microfiltration and drying are closely related to the reliable and effective performance of the product. As far as food is concerned, under appropriate temperature and humidity, bacteria and mold in food will multiply at an alarming rate, causing food to spoil, causing dampness and discoloration. Electronic products can also cause metal oxidation due to high humidity, resulting in defects. For example, fogging, condensation, and yellowing of the light inside the lamp affect the visual effect and driving safety, blurred images of the monitoring probe, oxidation of internal electronic components, short circuit, etc., causing safety accidents, such as the use of desiccant on the lamp and monitoring probe. , some shells have a beautiful appearance, many types of lamps in the shell, and co...

Electronic products can also cause metal oxidation due to high humidity, resulting in defective

For example, fogging, condensation, and yellowing of the light inside the lamp affect the visual effect and driving safety, blurred images of the monitoring probe, oxidation of internal electronic components, short circuit, etc., causing safety accidents, such as the use of desiccant on the lamp and monitoring probe. , some shells have a beautiful appearance, many types of lamps in the shell, and complex curved surfaces of the reflector. After the shell is turned on, the air circulation and ventilation system in the shell is not smooth, and there is humidity in the sharp corners of the shell or on the edge of the shell. Larger air eddies, the moisture and water molecules in this local air vortex will be fogged on the inner surface of the glass bulb with temperature difference, and condensation water droplets will appear when the fogging is serious. For the problem of fogging and condensation, many shell factories install desiccant packages such as silica gel and bentonite in the shell. The characteristics of desiccant packages such as silica gel and bentonite are disposable and irreversible, and the life of drying agglomerates is short. 1~2 The desiccant needs to be replaced every month when the desiccant fails, and some shells are slightly larger, requiring 2 to 4 desiccant packs, which occupy a large space in the shell and touch the electrical parts of the shell. Vibration touches the package and causes the user to increase the cost of after-sales maintenance and safety hazards

[0003] There are also multiple packs of desiccant built into the surveillance camera. If the desiccant is not replaced in time after it fails, in complex weather environments such as cloudy and rainy days, seaside docks and other places, it often causes security problems such as monitoring failure and blurred images due to fogging in the housing.
