Abstract
The utility model relates to an anti-freezing flat plate solar water heater which comprises a flat plate collector, a heat-preservation water tank and an upper circulating pipe and a lower circulating pipe which are respectively connected with the flat plate collector and the heat-preservation water tank, wherein a circulating water pump is in series connection with the upper circulating pipe or the lower circulating pipe. The circulating water pump is additionally arranged in the circulating pipeline and started when the outside air temperature is below zero in winter, and the water in the flat plate collector is kept to circularly flow to prevent from being iced, therefore, not only the anti-freezing effect is good, but also the structure is simple, and the manufacturing cost is lower.
Description
Technical field
The utility model relates to a kind of flat plate solar water heater, relates to a kind of antifreeze flat plate solar water heater specifically.
Background technology
Solar water heater is to utilize solar energy to be converted into heat energy water is heated to high-temperature from low temperature, to satisfy the device that the hot water of people in life, production uses.Flat plate solar water heater mainly is made up of flat plate collector, attemperater and upper and lower circulation pipe at present, and following circulation pipe is delivered to the cold water in the attemperater in the flat plate collector, and upper circular tube is delivered to the hot water that flat plate collector produces in the attemperater.The employed flat plate collector of flat plate solar water heater has two kinds of glass-vacuum tube heat collector and metal plate heat collectors, no matter be glass-vacuum tube heat collector and metal plate heat collector, when outside air temperature reaches subzero in the winter time, all exist and very easily break after freezing in the problem of damaging, particularly glass-vacuum tube heat collector of easily enduring cold.Even the metal plate heat collector because employed copper pipe is thinner in the heat collector, freeze in the pipe very easily cause body especially the body weld break, thereby cause heat collector to damage.Freezing in order to prevent heat collector, people normally keep the state that drips with the water emptying in the water tank or with hot water outlet, though this way can prevent that heat collector is not damaged by frost, shortcoming is operation inconvenience, and cause the waste of water resource.Another kind of way is to adopt electrically heated mode, installs electric calorifie installation in heat collector additional, utilizes electrical heating to make the inner intensification of heat collector to resist low temperature, though antifreezing effect is good, and complex structure, manufacturing cost increases.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of antifreeze flat plate solar water heater is provided, and can restrain the problem that prevents to cause because of low temperature the heat collector damage.
For achieving the above object, the utility model has adopted following technical scheme: it comprises flat plate collector, attemperater and the upper and lower circulation pipe that connects flat plate collector and attemperater, is serially connected with water circulating pump on upper circular tube or the following circulation pipe.When outside air temperature reach subzero after, start water circulating pump, make that the water in the flat plate collector can keep circulating, avoid icing, to reach antifreeze purpose.
For the water in the flat plate collector can be circulated fully, described water circulating pump is serially connected in down on the circulation pipe, during water circulating pump work, makes the water reverse flow from top to bottom in the flat plate collector, is forced to deliver in the attemperater by following circulation pipe again.
It also comprises a temperature switch circuit of being made up of temperature sensor and control circuit, and when temperature was below or above design temperature, the water circulating pump power supply is connected or closed to described temperature switch circuit.
As shown from the above technical solution, the utility model has been set up a water circulating pump in circulation line, when outside air temperature reaches subzero in the winter time, start water circulating pump, make that the water in the flat plate collector can keep circulating, avoid icing, good freezing protection effect not only, and simple in structure, only needing increases a micro pump, and manufacturing cost is lower.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, the utility model comprises flat plate collector 5, attemperater 3 and the upper and lower circulation pipe 4,6 that connects flat plate collector 5 and attemperater 3, is serially connected with water circulating pump 7 on the following circulation pipe 6. Pipeline 1 and 2 is respectively cold water inlet road and hot water effluent's pipeline of attemperater 3 among the figure.When outside air temperature reach subzero after, start water circulating pump 7, make that the water in the flat plate collector can keep circulating, avoid water icing in flat plate collector.
Water circulating pump can adopt artificial opening ways, also can adopt the automatic open close mode.Water circulating pump adopts artificial opening ways, and the power switch of water circulating pump is located at indoor.When adopting the automatic open close mode, install a temperature switch circuit of being made up of temperature sensor and control circuit additional on attemperater, when temperature was lower than design temperature such as zero degree, temperature switch circuit was connected water circulating pump power supply, water circulating pump work; When temperature was higher than design temperature such as zero degree, temperature switch circuit was closed the water circulating pump power supply, and water circulating pump quits work.
