Abstract
The utility model discloses a freeze resistant device for a solar water heater. The utility model is composed of a water supply device, a heat preservation water storage tank, a hot water circulating pipe, a cold water circulating pipe, a heat collector, and valves, wherein, the water supply device (1), the hot water circulating pipe (3), and the cold water circulating pipe (5) are arranged on the heat preservation water storage tank (2); the hot water circulating pipe (3) is connected with the upper end of the heat collector (6); the cold water circulating pipe (5) is connected with the lower end of the heat collector (6); the cold water circulating pipe (5) which is arranged at the lowest point of the heat collector (6) is provided with the valve (7) which is arranged at the lowest point of the circulating level of the heat collector; the upper end of the cold water circulating pipe (5) is provided with the valve (8) of the cold water circulating pipe; the hot water circulating pipe (3) is provided with the valve (9) of the hot water circulating pipe. After the valves are arranged on a water heater, the freeze resistant performance of the water heater can reach 50 DEG C below zero, and the heat preservation performance of the water heater can be enhanced.
Description
Technical field
The utility model relates to solar water heater, the freeze proof device of particularly a kind of solar water heater.
Background technology
Present plate type solar water heater thermal efficiency height, the heat production water yield is big, and is easy to maintenance, long service life, but its heat-insulating property is poor, and anti-freezing property is poor, can only be not less than subzero 10 ℃ area at temperature and use.
Summary of the invention
The purpose of this utility model is: provide a kind of solar water heater freeze proof device, by can reach heat-insulating property freeze proof and the enhancing water heater after on the water heater several valves being installed.
Formation of the present utility model: by water replanishing device, the insulation water storage box, the hot-water circulation pipe, cool water circulating pipe, heat collector, heat collector cyclical level lowest part valve, cool water circulating pipe valve and hot-water circulation pipe's valve are formed, go up installation water replanishing device (1) at insulation water storage box (2), hot-water circulation pipe (3) and cool water circulating pipe (5), hot-water circulation pipe (3) is connected with the upper end of heat collector (6), cool water circulating pipe (5) is connected with the lower end of heat collector (6), following on the bad pipe (5) at the lowest part cold water of heat collector (6) has heat collector cyclical level lowest part valve (7), in the upper end of cool water circulating pipe (5) cool water circulating pipe valve (8) is arranged, hot water circuit tube valve (9) is arranged on hot-water circulation pipe (3).
Compared with the prior art, the utility model is respectively installed a valve at the horizontal lowest part of water heater hot-water circulation pipe, cool water circulating pipe and solar thermal collector, when temperature is in particular state, be that valve closing on hot water, the cool water circulating pipe is in keeping warm mode between subzero 50 ℃ to 45 ℃ above freezing, when temperature is lower than below 0 ℃, be in the valve open of the horizontal lowest part of heat collector, the water of the whole heat collector of emptying inside is in freeze proof state.Just can make it freeze proofly reach subzero 50 ℃ by the several dress valves of peace on water heater, the enhancing heat-insulating property.
