Description
Technical field
The present invention relates to a kind of device that solar heat catcher is carried out overtemperature protection.
Background technology
Solar energy heating is the core component of Solar Energy Heat Utilization System, and solar thermal collector absorbs the light of solar radiation,
Producing the biggest heat energy, it is provided that power endlessly, it is like " heart " of people, and heart once stops beating, and people is with regard to nothing
Method is lived, then solar thermal collector once damages, and these hot-water heating systems also can lose vigor.Special heat sink, absorbs
Solar radiation, changes into heat energy, then transfers thermal energy to water energy parts.Heat collector according to the difference of temperature, be divided into low temperature,
Middle temperature, high temperature, solar thermal collector belongs to low form.The most different standards has different classification, such as, also follows the tracks of collection
Hot device and non-tracking heat collector, according to heat collector, whether whole day is divided into around solar motion for it.
In heat collection is operated, when especially collection solar heat generates electricity, heat collector has
Excellent operating temperature, the efficiency that heat energy converts when optimum operating temperature is the highest.But existing heat collecting apparatus is usually because of interior
The problems such as portion's operating temperature is too high, causes ageing equipment too fast, actual heat transformation efficiency reduction.
The boiling point of liquid is saturated vapour pressure and the external pressure of liquid temperature time equal.In certain outer pressure, first group
The liquid divided has the boiling point values determined, for the dual-fluid system of a complete miscibility, boiling point is not only relevant with external pressure, goes back and liquid
Composition relevant.That is the boiling point of dual-fluid system can adjust boiling point according to composition.Therefore, two kinds of liquid are selected
Mix required boiling point, i.e. gasification point.Convection current the scattering and disappearing for the temperature in container that liquid is internal before reaching boiling point
Considerably less.But when liquid reaches boiling point, gasify in a large number, now can take away the amount of heat in liquid.
Summary of the invention
It is an object of the invention to provide a kind of overtemperature protection system to solar thermal collector.
To achieve these goals, the present invention includes, a lagging casing, and this lagging casing is made up of facade and bottom surface,
It is fixed with Low-E face glass at its top end opening, in described lagging casing, fixes heat collection layer, the end of this heat collection layer
A heat transmission coil pipe is fixed in face, and an overheated phase transformation case is fixed in the bottom surface of this heat transmission coil pipe, filling in this overheated phase transformation case
Having ethylene glycol solution, the top of described overheated phase transformation case to connect with vapor lamp, the bottom of this phase transformation case connects with a return duct, institute
Stating vapor lamp and stretch out the top connection of lagging casing and a condenser, described return duct stretches out lagging casing and the end of a condenser
End connection.
By arranging overheated phase transformation case, when temperature is higher than design temperature, the ethylene glycol solution in superheated header, phase changing the flow of QI-blood
Changing, gasifying gas is quickly discharged, and takes away substantial amounts of heat, so that temperature quickly reduces the temperature reaching efficient operation.Work as temperature
When degree is reduced to below boiling point, gasification stops, and reenters liquid condition.The now heat exchange between liquid and the external world is very
Few, the temperature within device is affected and substantially can ignore, reach basic adiabatic state such that it is able to ensure that thermal-arrest efficiently enters
OK.
Preferably, it is provided with a breathing waterproof film in described vapor lamp.Breathing waterproof film is prevented from liquid and enters vapor lamp.
Preferably, it is positioned at heat collection upper end once in described lagging casing and fixes a printing opacity heat insulation layer.So can carry
The heat insulation effect of high whole device.
Accompanying drawing explanation
Fig. 1 is this practicality schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in detail.
As it can be seen, a kind of solar energy overtemperature protection system, including a lagging casing 1, this lagging casing 1 by facade and
Bottom surface forms, and is fixed with Low-E face glass 2, fixes heat collection layer 4, this heat in described lagging casing 1 at its top end opening
A heat transmission coil pipe 5 is fixed in the bottom surface of amount collecting layer 4, and an overheated phase transformation case 6 is fixed in the bottom surface of this heat transmission coil pipe 5, should
Being filled with ethylene glycol solution in overheated phase transformation case 6, the top of described overheated phase transformation case 6 connects with vapor lamp 71, this phase transformation case 6
Bottom connects with a return duct 72, and described vapor lamp 71 stretches out lagging casing 1 and connects with the top of a condenser 7, described backflow
Pipe 72 stretches out lagging casing 1 and connects with the bottom of a condenser 7.
A breathing waterproof film 73 it is provided with in described vapor lamp 71.
Be positioned in described lagging casing 1 heat collection once 4 upper end fix a printing opacity heat insulation layer 3.
By arranging overheated phase transformation case, when temperature is higher than design temperature, the ethylene glycol solution in superheated header, phase changing the flow of QI-blood
Changing, gasifying gas is quickly discharged, and takes away substantial amounts of heat, so that temperature quickly reduces the temperature reaching efficient operation.Work as temperature
When degree is reduced to below boiling point, gasification stops, and reenters liquid condition.The now heat exchange between liquid and the external world is very
Few, the temperature within device is affected and substantially can ignore, reach basic adiabatic state such that it is able to ensure that thermal-arrest efficiently enters
OK.The adjustment of the boiling point of ethylene glycol solution has substantial amounts of related data, now provides a part of solution boiling point data, is shown in Table 1.
