Description
Technical field
The utility model relates to solar thermal collector technical field, is specifically related to a kind of respirator of flat-plate solar collector.
Background technology
Along with the raising day by day of people's living standard, domestic hot-water has become a part indispensable in people's daily life.Flat plate solar water heater because it is efficient, longevity, cost low (with metal tube comparison), easy for installation, simple, floor space is little, not limited by installation environment, can be arranged on balcony, window, roof, wall first-class, and it is high to adopt heating rate, very energy-conservation, use simple, quick and easy safety, be deeply subject to users' favor.
For flat plate solar water heater system, flat-plate solar collector is wherein critical component.Its quality has directly determined the quality of flat plate solar water heater mass of system.For the flat-plate solar collector of any structure, its requirement is all that inside can not be infiltrated moisture, enter impurity, and inner body should not bear excessive pressure reduction and cause structure generation deformation even to destroy simultaneously.
Existing flat-plate solar collector is divided into pore type and hermetic type.Pore type flat plate collector has certain respiratory function, can make flat-plate solar collector generation in service to obtain autobalance with extraneous positive and negative pressure, prevent from therefore producing to flat-plate solar collector structural damage.Flat-plate solar collector goes manufacturing in process all in the remnants of material therefor and equilibrium water conten can being brought into the flat-plate solar collector cavity of making, in use have again new outside moisture (as rainwater, spray test etc.) or moisture and infiltrate in cavity, this has further strengthened the moisture in heat collector cavity.These moisture can evaporate and breathe out by the gap of flat-plate solar collector in the time of flat-plate solar collector air drying or hot operation, but limited because of respiration capability, whole steam can not breathed out.Therefore in the time that temperature reduces, residual steam can be condensed into again water droplet and stick to table and absorber surface in transparent cap rock and cause transparent cap rock transmittance to decline, solar energy is injected energy minimizing; Heat-insulating material makes moist, and thermal conductivity factor rises, and heat-insulating property worsens, and heat waste increases; Absorbed layer makes moist, and makes the rotten degeneration of coating; On dissimilar metal tube sheet, can produce the problems such as electrochemical corrosion.
And hermetic type flat plate collector and pore type is just in time contrary, because of airtight moistureproof and waterproof, but can therefore there is new peculiar problem, when heat collector temperature that Here it is raises, chamber pressure increases excessive.Flat-plate solar collector normally moves and can, in positive and negative 20KPa left and right, when in extreme stagnation temperature, even can reach 60KPa, and this even destroys the distortion that causes cavity.
No matter the flat-plate solar collector of which kind of existing type all can be because of making moist or pressurized causes flat-plate solar collector hot property decline, durability and reliability decrease, the lost of life.
Utility model content
One of the purpose of this utility model is to provide a kind of respirator, to solve the above problems.
A kind of respirator, comprises permeability cell and breather plug, and described breather plug is arranged in described permeability cell, and described breather plug is provided with cavity, is provided with waterproof ventilated membrane and hydroscopic fast-drying fiber in described cavity, and described hydroscopic fast-drying fiber is arranged at described waterproof ventilated membrane lower end.
Be provided with hydroscopic fast-drying fiber in the lower end of waterproof ventilated membrane, like this, steam can follow other gases to discharge in permeability cell, like this, can not cause the excessive internal structure that causes of permeability cell internal pressure to destroy, simultaneously, even if there is no the steam condensation of discharging, also can be absorbed fast and again discharge in steam mode by hydroscopic fast-drying fiber, and due to the existence of waterproof ventilated membrane, liquid can not enter in permeability cell from outside, ensured dry in permeability cell, has realized waterproof and dampproof in permeability cell and has possessed gas permeability simultaneously and regulate inside and outside differential pressure.
Further, described waterproof ventilated membrane is dustproof and waterproof ventilated membrane.Dustproof and waterproof ventilated membrane can also effectively prevent that dust from entering in respirator.
Further, described waterproof ventilated membrane is eptfe membrane.Eptfe membrane is the common used material of making waterproof ventilated membrane.
Further, described hydroscopic fast-drying fiber is bamboo fibre.Bamboo fibre moisture pick-up properties is good, and special quick-drying, can regenerate at a lower temperature, and cost is lower, and raw material is easy to get.
Further, described breather plug is movably set in described permeability cell, and described breather plug lower end is provided with buckle structure.By buckle structure, can in needs, manually pull up breather plug, can effectively improve hydrofuge speed.
Further, also comprise capping, described capping is arranged at described breather plug upper end, and described capping side is provided with opening.The setting of capping prevents the directly invasion and attack to waterproof ventilated membrane of outside bulky grain gravel when can ensuring respiration, extend the service life of waterproof ventilated membrane.
The utility model also provides a kind of flat-plate solar collector, and described flat-plate solar collector comprises above-described respirator.
The beneficial effects of the utility model are by waterproof ventilated membrane and hydroscopic fast-drying fiber are set in breather plug, realized breathing apparatus for good gas permeability effectively waterproof, hydrofuge, moisture resistance simultaneously, make respirator meet some equipment be not subject to interior pressure simultaneously needs be dried the condition of work.Comprise that the flat-plate solar collector of this respirator effectively improves and stablized the thermal efficiency of flat-plate solar collector, has extended the service life of flat-plate solar collector.
