The beneficial effects of the utility model, the utility model inventors have found that causing existing solar energy matched straight One main cause of the heating effect difference of hot type heating arrangement is, since heating main body has multiple surfaces, and in use only Only radiated by radiating surface, so, the other surfaces in addition to radiating surface of heating main body be easy to cause a large amount of invalid Heat dissipation, although there is insulating layer to work, still causes the thermal loss of heating main body and causes to waste, to cause its confession It warms up ineffective；And on the other hand, the outside conducting effect of heat of heating main body radiating surface is also unsatisfactory.

For this purpose, the inventor of the utility model is infrared by being formed in insulating layer with the surface that heating main body is bonded to each other Low emissivity layer be easy to cause largely invalid dissipate with the other surfaces in addition to radiating surface for cooperateing with insulating layer and avoid heating main body Heat.Meanwhile using being formed with infrared high radiating layer on the radiating surface of heating main body；Sufficiently to improve the radiating surface of heating main body The outside conducting effect of heat.In this way, from a point heating effect for raising directly-heated type heating arrangement in terms of above two.

By compared with conventional heating system, verifying and finding this reality the directly-heated radiant type heating arrangement of the utility model It is only the 30%~50% of conventional heating system with the heating energy consumption of New-type heating mechanism.And heating comfort level is substantially better than routine Heating system, and obtain the approval of independent peasant household.

Meanwhile so that the solar heating system in use, utilizes multiple first circular arcs concave surface and multiple second The form of circular arc concave surface, the intensity of illumination that sunlight is gathered the straight sections of thermal-collecting tube is higher, and experiment shows in low temperature -15 Under DEG C environment, 14MJ/ ㎡ days irradiation is provided under 60 DEG C of heating heat conditions, collecting efficiency can achieve 45% or more, than routine Ordinary flat solar thermal collector or vacuum tube solar heating element collecting efficiency for domestic hot-water are enhanced about more than once.From And ensure that the heating effect of directly-heated radiant type heating arrangement, to improve to indoor heating temperature, and cost is not It is obviously improved, there is significant economic benefit and practicability.

Also, by the collective effect of the first circulation of pipeline mechanism pump, second circulation pump and electric heating furnace, guarantee not only Directly-heated type heating equipment can be heated by solar thermal collector in the case where daytime is sunny, and also It realizes and still is able to heat directly-heated type heating equipment by electric heating furnace at cloudy day or night.

On the other hand, the inventor of the utility model also found, the heating effect of existing solar heating system is bad A main cause be that since system often uses liquid to conduct heat as working medium, and the impurity of air is often dissolved in In working medium, and under temperature rising condition, these gases can be separated with the working medium of liquid, and due to the expansion and compressibility of gas Relative liquid is more prominent, and the heat-transfer effect of gas is greatly lowered in this, so as to cause directly-heated type heating system to interior Heating temperature it is not high so that heating effect is unsatisfactory.Therefore it is badly in need of excluding gas from system, for this purpose, this is practical It is novel by by the input terminal of the output end of a solar thermal collector and another solar thermal collector simultaneously with exhaust blowdown pipe Connection, exhaust blowdown pipe offers exhaust gas supplementing opening, so that the solar heating system is formed as non-pressure system, and sharp simultaneously Gas present in whole system is excluded with exhaust blowdown pipe 808, so that working medium used in whole system be made to keep as far as possible For liquid, to improve the biography warm nature energy of the system.And then directly-heated type heating system is improved to indoor heating temperature, so that adopting Warm effect is more ideal.

In conclusion being solved by the directly-heated type medium temperature non-bearing type solar heating system aforementioned mating with solar energy It is not high to indoor heating temperature existing for the directly-heated type heating system of formation, so that the problem that heating effect is unsatisfactory.

According to the accompanying drawings to the detailed description of embodiment, it is practical new to will become more apparent to one of ordinary skill in the art this Above-mentioned and other purposes, the advantages and features of type.
