Be vacuum collector and circulation line inner product water freezing bursting by freezing vacuum collector and the circulation line that prevents outdoor low temperature environment, the anti-freezing structure that the solar water heater of existing indirect cyclic process structure is taked has usually: 1) evacuation port is set being positioned on the outdoor vacuum collector, when sombre sky or night, the water in the vacuum collector is drained, thereby prevent that vacuum tube is by bursting by freezing; 2) heat-insulation layer all is set being positioned on outdoor vacuum collector and two circulation lines, and on two circulation lines, all be provided with heating tape, so that the water temperature in outdoor vacuum collector and the circulation line was unlikely to low when sombre sky or night, thereby prevent that vacuum tube is by bursting by freezing.
Above-mentioned first kind of anti-freezing structure uses inconvenience and non insurance, in case certain does not discharge the water in the vacuum collector, vacuum tube is promptly scrapped whole vacuum collector by bursting by freezing.Though the heating tape of above-mentioned second kind of anti-freezing structure can keep the water temperature in the circulation line, the water in the vacuum collector only depends on heat-insulation layer still to be difficult to deal with low temperature environment, and is still of no avail for the cold snap in winter of the north.
The utility model content
The technical problem that the utility model solves is: propose a kind of solar water heater that can thoroughly prevent outdoor vacuum collector and circulation line bursting by freezing in low temperature environment.
In order to solve the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of anti-freezing solar water heater, comprise two circulation lines that are placed in indoor storage tank, are placed in outdoor vacuum collector and connection storage tank and vacuum collector, one of described circulation line is attached with heater element.
The inventor finds by the further investigation to existing indirect cyclic process structure solar water heater: vacuum collector must be installed in outdoor because of needs absorb sunshine, on north night in winter or daytime in winter during rainy weather,, vacuum collector is difficult to also guarantee that its water that includes does not freeze even being provided with heat-insulation layer; All wrap up the anti-freezing structure of heating tape as for aforesaid two circulation lines, owing to the water in two circulation lines does not have the temperature difference each other and can not form mobile, that is to say that the water in vacuum collector, circulation line and the storage tank all remains static, therefore only to the heating of the water in two circulation lines, can not guarantee that still the water in the vacuum collector does not freeze.And opposite be, storage tank is because of being arranged on temperature higher indoor (north is indoor warm winter), and the water temperature that storage tank includes is higher.In view of the above, the inventor courageously imagines: form recycled back between the water at low temperature of the high-temperature water of storage tank and vacuum collector and flow that (hot water flows to lower from eminence if can make, to flow to eminence from lower just in time opposite with existing hot water), then can thoroughly solve outdoor vacuum collector and the circulation line bursting by freezing problem of being positioned at.
Anti-freezing solar water heater of the present utility model just is being based on above-mentioned discovery and imagination and the anti-freezing structure that carries out improves, and the inventor selects only to wrap up heater element on one of two circulation lines dexterously.When night in winter or daytime in winter rainy weather use, the heater element of opening on one of two circulation lines heats this circulation line, article two, the water temperature in the circulation line forms the temperature difference, thereby between two circulation lines, produce pressure reduction (thermal siphon), so just can between vacuum collector and storage tank, produce reverse convection circulation, the storage tank high-temperature water that promptly is positioned at eminence is toward vacuum collector stream, and the vacuum collector water at low temperature that is positioned at lower is toward storage tank stream.Heating by heating tape keeps two circulation lines to have water temperature difference all the time, and this reverse convection circulation is sustainable carrying out.
The perfect of technique scheme is: described storage tank, vacuum collector and two circulation lines constitute by the water at low temperature in one of described circulation line guiding vacuum collector and flow to storage tank and high-temperature water in the storage tank is flowed to the self-circulation system of vacuum collector by two of described circulation line after described heater element heats up.
To sum up, compare existing solar water heater, anti-freezing solar water heater of the present utility model is broken through tradition to the thinking set of two circulation lines heating with the water freezing that prevents circulation line, by the structure of ingenious design to the heating of wall scroll circulation line, make to form between vacuum collector when low temperature environment and the storage tank and differ from the lasting recycled back of the existing high underflow of hot and cold water to circulation, thereby thoroughly stop vacuum collector and circulation line by bursting by freezing, for solar water heater antifreeze provides a kind of brand-new powerful mean.
Further improving of technique scheme is: described heater element is that the band shape that is wrapped on one of described circulation line is limit warm electric heating device certainly, the input external power supply of described heater element, described band shape is from limitting warm electric heating device to include heating, temperature sensor and controller.
