Background technology
Main flow flat-plate solar collector on the market is to comprise compositions such as glass cover-plate, frame, heat-absorbing plate core, heat-insulation layer and backboard now.When flat-plate solar collector was worked, sunshine saw through glass cover-plate and shines on the heat-absorbing plate core, and solar radiant energy is absorbed by heat-absorbing plate core, changes heat energy into, and passed the heat transfer medium in the heat-absorbing plate core runner, heat transfer medium periodic duty.Meanwhile, the inner temperature of heat collector raises, and the inevitable inside at heat collector of high temperature air produces malleation; Out of doors under the environment, during the unexpected rainfall of temperature cataclysm, the glass cover-plate of its hot gas cools off rapidly, and the inner temperature of heat collector descends, thereby closed cavity forms bigger negative pressure in the inside of heat collector.The checker phenomenon of the positive and negative air pressure that heat collector is inner can cause housing distortion, reduces the sealing of sealing joint strip, and the air dust of external environment condition and steam can get into the heat collector internal cavities through seal clearance during negative pressure.After the inner steam of heat collector reaches certain saturation degree, when heat collector is worked, form a large amount of fogs or the small globule at the inwall of glass 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
In order to overcome the shortcoming that above-mentioned prior art exists; But the purpose of the utility model is to provide a kind of flat-plate solar collector of balance inner and outer air pressure; It has overcome existing flat-plate solar collector and because of the heat collector inner and outer air pressure that temperature shock causes adverse effect jumpy has taken place; The balance external and internal pressure reduces the sealing joint strip bursting stress, avoids moisture in heat collector, to assemble.
In order to address the above problem; The utility model adopts following technical scheme: but a kind of flat-plate solar collector of balance inner and outer air pressure; Comprise heat collector housing, glass cover-plate, be provided with the cavity that sealing joint strip and three surround heat collector between said heat collector housing and the glass cover-plate; Heat-absorbing plate core, heat-insulation layer are set in the cavity of said heat collector; Also comprise breather valve, the valve body of said breather valve is installed on the said heat collector housing, and gas-permeable channels is set in the valve body, and said gas-permeable channels one end is communicated with the cavity of said heat collector, the other end and outside atmosphere environmental communication.
The further technical scheme of the utility model:
But be somebody's turn to do in the flat-plate solar collector of balance inner and outer air pressure, described breather valve is arranged on the top of flat-plate solar collector.
But be somebody's turn to do in the flat-plate solar collector of balance inner and outer air pressure, said gas-permeable channels comprises bottom air-vent and top air-vent; Said top air-vent is horizontally disposed with.
But in the flat-plate solar collector that should balance inner and outer air pressure, a block is installed on the valve body top of said breather valve, and said block bottom surface is uncovered and communicate with said gas-permeable channels.
But be somebody's turn to do in the flat-plate solar collector of balance inner and outer air pressure, shutoff has the breathable polytetrafluoroethylene film in the gas-permeable channels of breather valve.
But in the flat-plate solar collector that should balance inner and outer air pressure, described breather valve and heat collector housing are through being threaded.
But be somebody's turn to do in the flat-plate solar collector of balance inner and outer air pressure the sealing of the contact position of the valve body of described breather valve and heat collector housing and/or heat-insulation layer.
The beneficial effect of the utility model is: the inner and outer air pressure of the breather valve ability balance heat collector that it is provided with; Protection heat collector housing, sealing joint strip etc. do not receive 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 intrusions such as heat collector external corrosion property liquid; Simplicity of design, cost is low, and is easy to install, dependable performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is structure and the user mode sketch map of the utility model embodiment;
Among the figure: 1 heat collector housing, 2 heat-insulation layers, 3 heat-absorbing plate cores, 4 glass cover-plates, 5 sealing joint strips, 6 breather valves, 61 polytetrafluoroethylene films, 62 top air-vents, 63 bottom air-vents, 64 blocks.
The specific embodiment
As shown in Figure 1, but the flat-plate solar collector of this balance inner and outer air pressure comprises heat collector housing 1, glass cover-plate 4, is provided with the cavity that sealing joint strip 5 and three surround heat collector between said heat collector housing 1 and the glass cover-plate 4; Heat-absorbing plate core 3, heat-insulation layer 2 are set in the cavity of said heat collector.
But the flat-plate solar collector that is somebody's turn to do the balance inner and outer air pressure also comprises breather valve 6, and this breather valve 6 is arranged on the top of flat-plate solar collector.The valve body of breather valve 6 is through being threaded on the heat collector housing 1.The contact position sealing of the valve body of breather valve 6 and heat collector housing 1 and/or heat-insulation layer 2.
In the valve body of breather valve 6 gas-permeable channels is set, this gas-permeable channels comprises bottom air-vent 63 and top air-vent 62; Top air-vent 62 is horizontally disposed with.Gas-permeable channels one end i.e. bottom air-vent 63 is communicated with the cavity of heat collector, and the other end is top air-vent 62 and outside atmosphere environmental communication.
A block 64 is installed on the valve body top of breather valve 6, and 64 bottom surfaces of blocking a shot are uncovered and communicate with said gas-permeable channels.Shutoff has breathable polytetrafluoroethylene film 61 in the gas-permeable channels of breather valve 6.
When heat collector was worked, sunshine can see through glass cover-plate 4 and shine on the heat-absorbing plate core 3, and this moment, the internal temperature of flat-plate solar collector raise, and formed malleation in the cavity of heat collector, and inner hot-air and moisture can be discharged through the gas-permeable channels of breather valve 6.
When rainfall or other factors cause temperature shock; Glass cover-plate 4 is lowered the temperature rapidly; The inside of flat-plate solar collector forms negative pressure, and the air of outdoor environment can get into the inside of heat collector through breather valve 6, owing to there is polytetrafluoroethylene film 61; Outside the air dust of outdoor environment, steam etc. are blocked in, can't get into the inside of flat-plate solar collector.Block also can play and stop that dust gets into the inner effect of heat collector; In addition, the top air-vent is horizontally disposed with also and can plays this effect.
Owing to used breather valve 6, thereby protected heat collector housing 1, sealing joint strip 5 not to receive stress rupture, can in time discharge by the moisture that flat-plate solar collector is inner again, guarantee the effect and the life-span of heat collector.
