Abstract
A three cavity solar energy thermal-collecting tube for making the cold water rapidly risen in temperature and with good heat preservation effect comprises a inner glass tube and a outer glass tube sleeved on the outside of the inner glass tube, a vacuum layer is formed between the two tube wall, the inner glass tube is a sealed vacuum tube, and the heat conducting medium is provided in the vacuum tube, a first vacuum layer is formed between the outer glass tube and a glass tube sleeved on the outside of the outer glass tube. The utility model has the advantages that the utility model utilizes the heat conducting medium to process in the heat exchange, the heat conducting medium is characterized in that the heat absorption is fast at low temperature for rapidly processing in the heat exchange to make the cold water disposed in a storage device of a solar energy water heater rapidly heated and the heat preservation effect good.
Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe field, relates in particular to a kind of three chamber solar energy heat collection pipes.
Background technology
Solar energy utilization rate depends on the characteristic of irradiated body surface, if body surface to the absorptivity height in the solar spectrum, infrared emittance is low, then the absorptivity of this object and heat energy conversion ratio are higher.In early days, Application of Solar Energy promptly is used for the water heating is developed into now the most widely, and the whole world has tens million of apparatus for heating water by solar energy, and the solar water heating system main element that uses comprises at present: thermal-collecting tube, storage device, circulation line three parts; The most general solar energy heat collection pipe all adopts vacuum heat-preserving tube, this thermal-collecting tube is with outer glass pipe outward by inner glass tube and forms, and form vacuum layer between two tube walls, one end opening, the sealing of one end, the thermos flask inner bag of its profile such as same elongation, the outer surface of inner glass tube is provided with solar absorbing film in vacuum layer; Common apparatus for heating water by solar energy is that the openend of thermal-collecting tube is inserted in the storage device on the market, cold water in the storage device flows in the interior pipe of thermal-collecting tube, after thermal-collecting tube absorbs heat, temperature of cold water rises in the thermal-collecting tube, begin to rise and get back in the storage device, the cold water in the storage device is to flowing in the thermal-collecting tube, is heated then to be back in the storage device again, so circulation heating makes the water in the storage device pursue ashamed intensification.The shortcoming of this kind solar energy heat collection pipe is: water temperature rises slowly under the low temperature environment, can not utilize solar thermal energy fully; Have only a vacuum interlayer, heat insulation effect is poor.
Summary of the invention
The purpose of this utility model provides a kind of three chamber solar energy heat collection pipes that make the fast and high insulating effect of temperature of cold water rises.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of three chamber solar energy heat collection pipes, comprising: inner glass tube, outer glass pipe, outer glass pipe are enclosed within outside the inner glass tube, form vacuum layer between two tube walls, and its characteristics are: inner glass tube is provided with heat-conducting medium for the vacuum tube of sealing in the vacuum tube; Outer glass pipe is set with glass tube outward, forms first vacuum layer between glass tube and the outer glass pipe.
According to three above-mentioned chamber solar energy heat collection pipes, its characteristics are: the upper end of inner glass tube is a condensation end, and the lower end is a stiff end; Be respectively arranged with pipe clamp in the vacuum layer and first vacuum layer, pipe clamp is connected with the stiff end of inner glass tube in vacuum layer; Pipe clamp is connected with outer glass pipe in first vacuum layer.
The utility model has the advantages that: the utility model utilizes heat-conducting medium to carry out heat exchange, and the characteristics of heat-conducting medium are exactly that the low temperature heat absorption is fast, can carry out the interior fast and high insulating effect of temperature of cold water rises of storage device that heat exchange makes solar water heater fast.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of three chamber solar energy heat collection pipes, as shown in Figure 1, comprising: common inner glass tube 6, common outer glass pipe 4, outer glass pipe 4 is enclosed within outside the inner glass tube 6, form vacuum layer 7 between two tube walls, its characteristics are: inner glass tube 6 is provided with heat-conducting medium 9 for the vacuum tube 8 of sealing in the vacuum tube 8; Be set with common glass tube 2 outside the outer glass pipe 4, form first vacuum layer 3 between glass tube 2 and the outer glass pipe 4.In the present embodiment, the upper end of inner glass tube 6 is a condensation end 5, and the lower end is a stiff end; Be respectively arranged with pipe clamp 1 in the vacuum layer 7 and first vacuum layer 3, pipe clamp 1 is connected with the stiff end of inner glass tube 6 in vacuum layer 7; Pipe clamp 1 is connected with outer glass pipe 4 in first vacuum layer 3.
Operation principle of the present utility model is:
The utility model condensation end is inserted in the storage device of solar water heater, the rapid intensification gasified after heat-conducting medium in the vacuum tube absorbed solar heat, at the condensation end of vacuum tube exchange heat is passed to cold water in the storage device, be cooled to liquid state after having transmitted heat, be back to the stiff end of vacuum tube, be heated to form gas again and rise to condensation end and carry out exchange heat, circulate and so forth the cold water in the storage device is heated.
Because the utility model is that vacuum tube is with the vacuum layer structure outward, and the condensation end of vacuum tube inserts in the storage device, break so be exposed to the outer thermal-collecting tube of storage device, whole solar water heater system is leaked, can not influence the use of whole solar water heater system.
The composition of heat-conducting medium
The alcohol of potassium sulfate, purity 99.98%, acetone, distilled water, imbibition core.
