Abstract
The invention discloses a kind of using membrane module of moisture demisting in infrared radiation drying discharge shell and preparation method thereof, lamp rear cover, the both sides of the face of component cylinder are respectively connected with microporous barrier, in cylinder filled with can moisture absorption particle matter and efficient absorption far infrared radiation energy substance micro powder granule mixture；The die-cutting product of microporous barrier and cylinder side end face are welded to connect when preparation, then in cylinder it is filling can moisture absorption particle matter and efficient absorption far infrared radiation energy substance micro powder granule mixture, weld the die-cutting product of microporous barrier in cylinder other side end face；Lamp rear cover includes using the membrane module of moisture demisting in infrared radiation drying discharge shell, which is assemblied in the rear lid case with several through-holes.By the above-mentioned means, the present invention can ensure the generation without fogging dew condensation phenomenon in the shell of automobile lamp and electric/electronic device, on the minute surface in the shell of electronic equipment or smooth electronical elements surface there will be no the generations of fog phenomenon.
Description
Technical field
The present invention relates to a kind of membrane module using moisture demisting in infrared radiation drying discharge shell and its preparation sides
Method, lamp rear cover.
Background technology
With the aesthetic raising of China's automobile consumption, automotive type appearance is in streamline curved face type, especially Automobile more
Lamp is the eyes of automobile, and mode of appearance is more curving, lively beautiful, outside halogen bulb that car light maturation uses, xenon lamp, is increased newly
LED headlight new technologies；The car light of modernization, in order to pursue beauty, shape becomes increasingly complex, and complex-shaped also results in lamp
Temperature difference is generated in shell, therefore in outside air（Humidity）After, fog is easily generated, influences traffic safety.Automobile lamp
Curving and newly-increased LED headlight new technologies make automobile lamp clear bulb in offices such as cold place's curved surface, wedge angle transitional regions
The glass bulb inner surface fogging condensation in portion is heavier, and the technology of the common scattered mist dew removing of Foreign Automobile power also can't resolve above-mentioned influence
The car light of traffic safety coagulates mist condensation trouble.
Invention content
The invention mainly solves the technical problem of providing a kind of using moisture demisting in infrared radiation drying discharge shell
Membrane module and preparation method thereof, lamp rear cover, it can be ensured that without fogging in the shell of automobile lamp and electric/electronic device
The generation of dew condensation phenomenon so that electric property is not influenced by moist air environment, and is capable of the infiltration of blocks dust.
In order to solve the above technical problems, one aspect of the present invention is：It provides a kind of dry using infra-red radiation
The membrane module of moisture demisting in dry discharge shell, including：Cylinder and microporous barrier, cylinder both sides of the face are respectively connected with microporous barrier,
In cylinder filled with can moisture absorption particle matter and efficient absorption far infrared radiation energy substance micro powder granule mixture, moisture
Enter in cylinder from microporous barrier, is discharged from microporous barrier by mixture.
In a preferred embodiment of the present invention, reversible moisture absorption particle matter is reversible drier, bentonite, silica
It is one or more in aeroge, carbon molecular sieve, carbon aerogel adsorbent and water-absorbing resins.
In a preferred embodiment of the present invention, the substance micro powder granule packet of efficient absorption far infrared radiation energy-sensitive
It includes：One kind or more in carbon product, charcoal, tourmaline, far-infrared ceramic, zirconium carbide, metal oxide and silicon carbide
Kind.
In a preferred embodiment of the present invention, microporous barrier includes the hydrophobic oleophobic ability for continuing unidirectionally to be discharged moisture
Expanded PTFE coated film or the film with steam infiltration duct for having bilateral flow ability.
In a preferred embodiment of the present invention, ventilation or maintenance and debugging of the component with car light or electrical equipment assists
Rear cover is used in combination
The preparation method of the membrane module of moisture demisting in the invention further relates to use infrared radiation drying discharge shell：First
Prepare part needed for component, the die-cutting product of microporous barrier and cylinder side end face are welded to connect, then filling in cylinder inhales
The mixture of the substance micro powder granule of wet particle matter and efficient absorption far infrared radiation energy, finally in another side end face of cylinder
The die-cutting product of microporous barrier is welded, that is, completes the preparation of component.
In a preferred embodiment of the present invention, the die-cutting product of microporous barrier is to have to continue unidirectionally to be discharged the hydrophobic thin of moisture
The die-cutting product of the expanded PTFE coated film of oily ability or have bilateral flow ability with steam infiltration duct it is thin
The die-cutting product of film.
In a preferred embodiment of the present invention, when cylinder both sides are welded with being permeated with steam for bilateral flow ability
The die-cutting product of the film in duct, moisture enters inner barrel by steam infiltration duct in shell, by can moisture absorption particulate matter
The mixture of the substance micro powder granule of matter and efficient absorption far infrared radiation energy is discharged, extraneous air from steam infiltration duct
It is to enter enclosure interior after this membrane module dry filter, into shell being dry air.
In a preferred embodiment of the present invention, when cylinder side be welded with bilateral flow ability have steam permeability hole
The die-cutting product of the film in road, the other side are welded with the expanded PTFE for the hydrophobic oleophobic ability for continuing unidirectionally to be discharged moisture
The die-cutting product of coated film, moisture enters inner barrel by steam infiltration duct in shell, by can moisture absorption particle matter and
The mixture of the substance micro powder granule of efficient absorption far infrared radiation energy, is unidirectionally discharged from expanded PTFE coated film.
In order to solve the above technical problems, another technical solution used in the present invention is：A kind of lamp rear cover is provided, including
The membrane module using moisture demisting in infrared radiation drying discharge shell, the component are assemblied in several through-holes
In rear lid case.
The beneficial effects of the invention are as follows：The present invention can ensure in the shell of automobile lamp and electric/electronic device without fogging
The generation of dew condensation phenomenon so that electric property is not influenced by moist air environment, in the shell of auto electric electronic equipment
On minute surface or smooth electronical elements surface there will be no the generations of fog phenomenon so that the performance of auto electric electronic equipment is able to
It brings into play, has thoroughly overturned American-European-Japanese conventional method adjusted to humid control in shell, and be capable of the infiltration of blocks dust,
So that reaching free of contamination dirt level of confidentiality in the shell of auto electric electronic equipment.
