Abstract
The utility model relates to a solar energy water-heater using medium to heat the water, which comprises a solar energy collecting tube and a reservoir with cold water coming in to the tube in the bottom and hot water going out from the tube on the top. The utility model is characterized in that the medium chamber is also arranged at the end and outside the bottom of the reservoir. The medium chamber is provided with medium input on the top and is communicated with the energy collecting tube in the bottom. The utility model has the advantages that the structure is simple, and the reservoir and the energy collecting tube are resistant to the frost-caused cracking in winter.
Description
Technical field
The utility model relates to a kind of solar water heater, a kind of solar water heater with medium heating cold water of more specifically saying so.
Background technology
Be unable to do without hot water in the daily life, be heated to be hot water by cold water and need consumes energy, in order to save the energy limited on the earth, solar water heater has obtained using widely, department with good conditionsi and unit adopt large-scale solar water heater to provide hot water for the user concentrates, and what face was wide in a large number then is the popular solar water heater for own domestic hot water of installation separately of single household.The common deficiency of above-mentioned these solar water heaters is that storage tank and thermal-collecting tube are in the winter time easily by bursting by freezing, storage tank and thermal-collecting tube are in case by bursting by freezing, not only make troubles and increase maintenance cost to the user, and have a large amount of water and flow out, if solar water heater is installed in the roof, the water of these outflows drops down to ground from the roof just as raining, and causes the waste of water resource on the one hand, on the other hand the environment of influence inhabitation.In recent years, though there is numerous inventors that solar water heater has been carried out improvement in various degree from many aspects, be control device of 99220717.7 automatic tracking type solar water heater, 00215163.4 solar water heater single tube blank pipe etc. as the patent No., but all unresolved storage tank and thermal-collecting tube are in the winter time easily by the difficult problem of bursting by freezing.
Summary of the invention
The purpose of this utility model provides a kind of storage tank and thermal-collecting tube in the winter time can be by the solar water heater with medium heating cold water of bursting by freezing.
For realizing the purpose of invention, this solar water heater with medium heating cold water comprises thermal-collecting tube and storage tank, the cold water inlet pipe is equipped with in the bottom of storage tank, hot water out pipe is equipped with on top, its design feature is also to be provided with dielectric cavity outside an end of storage tank and bottom surface, and the top of this dielectric cavity is provided with the medium input pipe, the bottom is communicated with the inner chamber of thermal-collecting tube.
As to this improvement of heating the solar water heater of cold water, on the medium input pipe, be provided with check valve with medium.
As further improvement to this solar water heater with medium heating cold water, the cold water inlet pipe is positioned on the part of storage tank inner chamber and is densely covered with the ostium excurrens that Open Side Down, and hot water out pipe is positioned on the part of storage tank inner chamber and is densely covered with the water inlet aperture that opening makes progress.
During use, except with running water by the cold water inlet pipe to storage tank is filled water, also want the open check valve heat-conducting medium of in dielectric cavity and thermal-collecting tube, packing into, heat-conducting medium will be selected anti-icing fluid for use, after heat-conducting medium installed, because the effect of check valve, heat-conducting medium did not outflow.
The operation principle of this solar water heater with medium heating cold water is: the heat energy of the sun passes to heat-conducting medium by thermal-collecting tube, heat-conducting medium is heated, heated heat-conducting medium is given thermal energy transfer the cold water in the storage tank again, and cold water is become hot water, and is for people to use.Because heat-conducting medium can be selected cold-resistant antifreeze kind for use, dielectric cavity is positioned at the outside of storage tank again, thus the winter of cold thermal-collecting tube and storage tank can be by bursting by freezing.Even if meet beyond thought external force by chance thermal-collecting tube is broken, outflow be quantity heat-conducting medium seldom rather than a large amount of water.The cold water inlet pipe is positioned on the part of storage tank inner chamber and is densely covered with the ostium excurrens that Open Side Down, its effect is to lean on the pressure of running water to make cold water flow into the bottom of storage tank uniformly in adding the process of cold water, the life of lifting with the hot water uniform and stable, the uniform hot water of temperature is pooled in the hot water out pipe by the water inlet aperture on hot water out pipe of gathering again and flows out, avoided when using hot water water temperature fluctuated, the uncomfortable phenomenon of people is taken place.
From the above mentioned, this solar water heater with medium heating cold water, the installation site can height can be low, hot water is that the pressure by running water is flowed out by hot water out pipe, structure was both simple, storage tank and thermal-collecting tube in the winter time again can be by bursting by freezing.
Description of drawings
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings, and what accompanying drawing drew is the structural representation that heats the solar water heater of cold water with medium.
The specific embodiment
With reference to accompanying drawing, the described solar water heater of embodiment with medium heating cold water, comprise thermal-collecting tube 1 and storage tank 2, cold water inlet pipe 3 is equipped with in the bottom of storage tank 2, hot water out pipe 4 is equipped with on top, cold water inlet pipe 3 is positioned on the part of storage tank 2 inner chambers and is densely covered with the ostium excurrens 8 that Open Side Down, hot water out pipe 4 is positioned on the part of storage tank 2 inner chambers and is densely covered with the water inlet aperture 9 that opening makes progress, outside end of storage tank 2 and bottom surface, also be provided with dielectric cavity 5, the top of this dielectric cavity 5 is provided with medium input pipe 6, the bottom is communicated with the inner chamber of thermal-collecting tube 1, is provided with check valve 7 on medium input pipe 6.
In the present embodiment, except that above-mentioned technical characterictic, remaining is known technology, not in carefully stating.
