A kind of solar water heater of disturbance heatingTechnical field
The present invention relates to a kind of water heater, especially a kind of solar water heater of disturbance heating.
Background technology
Since oil price is unstable and the limitation etc. of climate change agreement, the importance of new regenerative resource become larger.It can be againThe raw energy includes solar heat, sunlight, biomass energy, wind-force, small power station, underground heat, ocean energy and waste energy etc., and new energySource includes fuel cell, liquefaction coal, gasification coal and Hydrogen Energy.Problem is sent out from new regenerative resource, particularly sunlightThe cost of electricity is not up to the power grid par for the cost for being equal to traditional thermal power generation using fossil fuel.But with technologyProgress is persistently reduced from the solar thermal power generation of the solar thermal power generation in new regenerative resource in cost of electricity-generating, andGenerating efficiency is being gradually increased.
Solar energy is converted into thermal energy and relies primarily on heat collector.At present solar thermal collector mainly have vacuum tube collector,Three kinds of heat pipe collector and vacuum flat plate collector.
The solar thermal collector of existing domestic solar water heater, during flowing in evacuated collector tube by waterHeat is absorbed, since evacuated collector tube is cylindrical-shaped structure, the solar energy irradiation in each face is uneven, therefore, causes at itThe uneven heating of the medium water of interior flowing is even, causes finally storage uneven to the coolant-temperature gage in boiler, there are portion temperaturesTherefore inadequate relatively cold water be easy to cause hot water temperature and does not reach requirement, and in winter, environment temperature is relatively low, general in the northAll over environment temperature in subzero, since the evacuated collector tube of solar thermal collector is arranged at outdoor, then vacuum heat-collecting tube capacityEasy bursting by freezing causes flow to lose and becomes ice, is further exacerbated by bursting by freezing, causes vicious circle, therefore, existing solar thermal collectorThere are the risk of bursting by freezing, safety is relatively low.
