Abstract
The utility model discloses a flat plate solar collector with a breather valve, comprising a flat plate solar collector. A breather valve is fixedly arranged on the top of the flat plate solar collector. A sealing ring is arranged at outer contact position. The through hole at bottom of the breather valve passes through a heat preservation layer of the collector and directly reaches the inner empty cavity of the collector. A ventilation hole at the upper part of the breather valve is communicated with an outdoor environment. A breathable oil and water resistance film is arranged in the ventilation channel of the breather valve. The utility model overcomes the adverse effect of the current flat plate solar collector that internal pressure and external pressure of the collector are changed rapidly, which is resulted from sudden change of temperature. The flat plate solar collector can balance internal and external pressure, reduce breaking stress of a shell and a sealing strip and prevent humidity from gathering in the collector.
Description
Technical field
The utility model relates to the solar water heater field, specifically belongs to a kind of flat-plate solar heat collector with breather valve.
Technical background
The device that can absorb solar radiation heat energy that existing flat-plate solar heat collector is made up of heat-absorbing plate core, housing, transparent cover plate, insulation material and relevant parts.When flat-plate solar heat collector is worked, sunlight sees through transparent cover plate and shines on the heat-absorbing plate core, wherein most of solar radiant energy is absorbed by heat-absorbing plate core, change heat energy into, and the heat transfer medium of biography in heat-absorbing plate core, the heat transfer medium periodic duty, the useful energy output of back as heat collector heats up.Meanwhile, the temperature of the inside closed cavity in the heat collector also rises very highly (especially temperature is higher under vexed solarization condition once in a while), and the high temperature expanded air is inevitable in the inner malleation that produces of heat collector; Out of doors under the environment, during the unexpected rainfall of temperature cataclysm, the transparent cover plate of heat collector cools off rapidly, and temperature descends in the chamber, thereby forms bigger negative pressure at the inside of heat collector closed cavity.The checker phenomenon of the positive and negative air pressure of heat collector internal cavities can cause housing distortion, reduces the sealing of sealing strip, and the air dust of external environment condition and steam can enter the heat collector internal cavities by seal clearance during negative pressure.After the steam in the cavity reaches certain degree of saturation, can when work, heat collector form a large amount of fogs and the small globule at the inwall of transparent cover plate, and can't discharge naturally, reduce the sunlight amount of incident, the service life of heat collector and heat absorption efficiency are reduced greatly.
The utility model content
The purpose of this utility model provides a kind of flat-plate solar heat collector with breather valve, overcome existing flat-plate solar heat collector and adverse effect jumpy has taken place because of the heat collector inner and outer air pressure that temperature shock causes, the balance external and internal pressure, reduce the sealing strip bursting stress, avoid moisture in heat collector, to assemble.
The technical solution adopted in the utility model is as follows:
A kind of flat-plate solar heat collector with breather valve, comprise flat-plate solar heat collector, described flat-plate solar collector top is fixed with breather valve, external synapsis is provided with sealing ring, the bottom air vent of breather valve is passed the internal cavities that the heat collector heat-insulation layer directly arrives heat collector, the top air-vent of breather valve communicates with outdoor environment, is provided with the ventilative oily hydrophobic membrane of hating in the gas-permeable channels of breather valve.
Described breather valve and heat collector shell are by being threaded.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The utility model adopts flat-plate solar heat collector top dress breather valve, the inner and outer air pressure power of breather valve energy balance heat collector, protection housing, sealing strip are not subjected to stress rupture, prolong equipment life, effectively prevent knot mist, dewfall in the heat collector internal cavities, strengthen the amount of incident of sunlight, effectively resist the intrusion of heat collector external acid, salinity and other corrosive liquids; Simplicity of design is simple in structure, and is with low cost, installation, convenient disassembly, dependable performance, safety and effectivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, breather valve 1 is installed in the top of flat-plate solar heat collector 2, and breather valve 1 closely is connected with heat collector shell 21 by Si Ya, and by rubber ring 13 sealings.The bottom air vent of breather valve 1 is passed the internal cavities that heat-insulation layer 22 directly arrives heat collector, and the top air-vent 12 of breather valve communicates with outdoor environment, is provided with EPTFE film 11 in the gas-permeable channels of breather valve 1.When heat collector 2 work, sunlight can see through transparent cover plate 24 and incide on the heat-absorbing plate core 23, and this moment, the internal cavities temperature of flat-plate solar heat collector 2 sharply raise, and formed malleation.Expanded air in the cavity and moisture can be discharged by breather valve 1; When the rainfall temperature shock, transparent cover plate 24 is lowered the temperature rapidly, the internal cavities of flat-plate solar heat collector 2 forms negative pressure, the air of outdoor environment can enter the internal cavities of heat collector by breather valve 1, owing to there is EPTFE film 11, outside the air dust of outdoor environment, steam are blocked in, can't enter the internal cavities of flat-plate solar heat collector 2.Owing to used breather valve 1; thereby protected heat collector shell 21, sealing strip 25 not to be subjected to stress rupture; again the moisture of flat-plate solar heat collector 2 inside is in time discharged, guarantee the best endothermic effect of heat collector, prolonged the service life of flat-plate solar heat collector 2.
Claims (2)
1. flat-plate solar heat collector with breather valve, comprise flat-plate solar heat collector, it is characterized in that: described flat-plate solar collector top is fixed with breather valve, external synapsis is provided with sealing ring, the bottom air vent of described breather valve is passed the internal cavities that the heat collector heat-insulation layer directly arrives heat collector, the top air-vent communicates with outdoor environment, is provided with the ventilative oily hydrophobic membrane of hating in the gas-permeable channels.
