Abstract
The invention discloses an ultrathin heat pipe solar thermal collector used for solar photo-thermal products, which is characterized in that the solar thermal collector has ultrathin thickness, can be bent and folded, can be separately placed with a thermoreceptor such as a water storage tank, and can be totally integrated with construction.
Description
Affiliated technical field
The present invention relates to a kind of solar heat pipe collector that is used for the solar energy hot product, it is characterized in that thickness is ultra-thin, can be bent and fold, can lay, can realize fully integratedization with building with thermoreceptor (as, water storage tank) split.
Background technology
Solar thermal collector is one of essential elements of solar energy hot product (as, solar water heater), is responsible for solar energy is converted into heat energy.That solar thermal collector in the market mainly contains is plate, vacuum tube type and heat-tube vacuum cast, but all has the one series of structural defective.Such as, the photo-thermal conversion efficiency of flat plate collector is on the low side, heat leak is higher.Vacuum tube collector exist easily leak, easy broken, heat leak is higher and the daylighting area availability is low shortcoming.The vacuum-tube heat-pipe heat collector then exists easy leakage, easy fragmentation and the low shortcoming of daylighting area utilization rate.Above-mentioned three kinds of solar thermal collectors also all have thickness excessive (＞100mm), can't lay, be difficult for integrated with the building realization, as to influence general character such as appearance of the city sight shortcoming with thermoreceptor (as, water storage tank) split.These shortcomings have become further promotes the use of the solar energy hot product, solar water heater product particularly, major obstacle.
Summary of the invention
The purpose of this invention is to provide a kind of solar thermal collector solar energy hot product, that can realize fully integratedization with building that is applicable to.
This heat collector is based on the heat pipe operation principle, by the states of matter variation absorption and the transmission heat of its liquid refrigerant.This liquid refrigerant is attracted in the transfusion plate that is installed in the flat transparent encapsulation bag.By the REFRIGERATION SYSTEM DRIVEN BY CAPILLARY FORCE power that this transfusion plate is provided, this liquid refrigerant can be transported to each corner of this heat collector equably.The transfusion plate absorbs and throws the light on it and be translated into heat energy.This heat energy will be adsorbed on the liquid refrigerant evaporation in the transfusion plate hole crack and be converted into liquid-gas phase and become latent heat.The gas phase working medium that generates flows to a heat exchanger that places in the thermoreceptor (as, water storage tank) under the driving of barometric gradient, and condensation and discharge latent heat of phase change there.Latent heat of phase change is absorbed by thermoreceptor.The liquid refrigerant that generates is under the effect of gravity or at the dirty feedback liquid of the driving of compression pump plate.
Because this heat collector can adopt the flexible material manufacturing and utilize capillarity to carry and distribute liquid refrigerant, it not only has ultra-thin characteristics, and can be under crooked and folded state operate as normal.On the other hand, because this heat collector adopts the heat pipe operation principle, it can be laid with the thermoreceptor split, and can play the effect of thermal diode, thereby can stop the leakage of heat in the thermoreceptor effectively.Therefore, traditional solar thermal collector is bulky, the daylighting area utilization rate is low, heat leak is higher, easy fragmentation, be difficult for the building realization integratedly, and influencing a series of shortcomings such as appearance of the city sight can be overcome one by one by the present invention.Utilize technical characterictic of the present invention can develop a series of new type solar energy photo-thermal products, as solar energy optical-thermal curtain wall, solar energy optical-thermal roofing and ultralight thin plate solar water heater.

The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the constructed profile of ultrathin heat pipe solar thermal collector.
Fig. 2 is one of embodiments of the invention: solar energy optical-thermal curtain wall, a) back sticking type, b) sandwich-type.
Fig. 3 is two of embodiments of the invention: the solar energy optical-thermal roofing.

The specific embodiment
Fig. 1 provides the constructed profile of ultrathin heat pipe solar thermal collector 100.It is by transparent enclosure bag 101, packed transfusion plate 102, liquid refrigerant 103 and gaseous working medium 104 in it, and tube connector 105 and heat exchanger 106 constitute.By getting rid of its inner nonvolatile gas, transparent enclosure bag 101 provides essential vacuum or low pressure working environment for infuse plate 102 and liquid refrigerant 103.Transfusion plate 102 is made by mushy material, and the capillary that wherein comprises can adsorb liquid refrigerant 103 and it is distributed on the transfusion plate equably and comes.Under the condition of given material, the thickness of transfusion plate 102 has determined the speed of its delivering liquid working medium 103, and its thickness is generally between one to several millimeters.The color of transfusion plate 102 can be coated with black and be beneficial to absorb sunshine.Have the transmission that some groove (not shown) that lead to tube connector 105 are beneficial to gaseous working medium 104 on the transfusion plate 102.Liquid refrigerant 103 is a kind of liquids that have low vapourizing temperature under vacuum or low pressure condition.
The operation principle of ultrathin heat pipe solar thermal collector 100 is as follows: sunshine is converted into heat energy and passes to by 102 absorptions of transfusion plates through encapsulation bag 101 and is attracted to its intrapore liquid refrigerant 103.Under the low pressure state, liquid refrigerant 103 evaporations of being heated change gaseous working medium 104 into, and this heat energy is converted into liquid-gas phase change latent heat simultaneously.Under the capillarity of transfusion plate 102 drove, the liquid refrigerant of above-mentioned local evaporation was replenished rapidly.The groove of the gas phase working medium 104 that generates on the driving lower edge of barometric gradient transfusion plate flows to the heat exchanger 106 that inserts a thermoreceptor (not shown) and is condensed into liquid refrigerant 103 there by tube connector 105, discharges latent heat of phase change simultaneously.The latent heat of phase change that discharges is absorbed by thermoreceptor.The liquid refrigerant 103 that generates is flowing back into transfusion plate 102 by tube connector 105 under the effect of gravity or under the driving at compression pump.
The relative position of heat exchanger 106 and transfusion plate 102 has determined the reflux type of liquid condensed working medium 103.If the position of heat exchanger 106 is higher than transfusion plate 102, liquid refrigerant 103 can be under the effect of gravity natural back flow.Otherwise, must working pressure pump (not shown) liquid condensed working medium 103 forced conveyance be fed back liquid plate 103.Select the tube connector 105 of suitable length and flexibility for use, thermoreceptor (as, water storage tank) can be installed in optional position apart from ultrathin heat pipe solar thermal collector 100.
It is pointed out that the heat transmission between ultrathin heat pipe solar thermal collector 100 and the thermoreceptor is unidirectional, promptly heat can only flow to thermoreceptor from heat collector.When the temperature of thermoreceptor is higher than the temperature of heat collector (as in the night), the heat transmission between them will be ended automatically.This is because heat needs the evaporation of liquid refrigerant 103 in heat exchanger 106 from thermoreceptor to the transmission of heat collector.But there is not liquid refrigerant 103 in the heat exchanger 106.This thermal diode feature can reduce effectively by the heat leak of thermoreceptor (as, water storage tank) at night.
Provide several specific embodiments of ultrathin heat pipe solar thermal collector 100 below.
