Abstract
The utility model relates to a freezing-proof flat-plate type solar water heater, which belongs to the technical field of solar facilities. The utility model relates to a freezing-proof solar water heater which is composed of a heat preservation water tank 2 and a heat collector 8. A heat exchanger 4 is arranged in the heat preservation water tank 2. Both ends of the heat exchanger 4 are respectively communicated with an upper circulation pipe 5 and a lower circulation pipe 1 which are inserted into the heat preservation water tank 2. Thus, the heat exchanger 4 and a heat absorbing plate core 7 form a closed system. An antifreeze solution with a high heat-conducting property is arranged in the closed system. The utility model has the advantages of simple structure, easy fabrication, good freezing-proof performance, high thermal efficiency, and long service life.
Description
The utility model belongs to the solar facilities technical field, relates to a kind of solar water heater that can prevent bursting by freezing.
Solar water heater of the prior art has solar water heaters such as flat, hot pin formula, closing-sunning type, no hot reflux formula, electron tubes type, and its structure mainly is made up of attemperater and heat collector, and attemperater and heat collector are by cross current.The thermal cycle of these solar water heaters is to form by the difference of water temperature, and the cold water in the heat collector heat-absorbing plate core is heated by radiation and flow to attemperater on the back, flow to heat-absorbing plate core under the water at low temperature in the attemperater and forms interior circulation.This endless form not only heat exchange effect is poor, and the water in the attemperater heats up slowly, and has water in heat-absorbing plate core and the circulation pipe, in case temperature drops to below 0 ℃, interior water freezes, and very easily causes heat-absorbing plate core and circulation pipe bursting by freezing.
The purpose of this utility model provides and a kind ofly can prevent to make in the winter time the heat-absorbing plate core in the heat collector and the solar water heater of circulation pipe bursting by freezing, thereby overcomes the deficiencies in the prior art.
For achieving the above object, antifreeze loop solar water heater of the present utility model is made up of attemperater, heat collector and upper and lower circulation pipe, heat-absorbing plate core is housed in the heat collector, the heat-absorbing plate core two ends are communicated with upper circular tube, following circulation pipe respectively, and upper circular tube and following circulation pipe insert attemperater from the two ends of attemperater; Be provided with heat exchanger in the attemperater, the two ends of heat exchanger respectively with insert attemperater in upper circular tube, circulation pipe is communicated with down, makes heat exchanger and heat-absorbing plate core form a closed system, and the high anti-icing fluid of heat conductivility is housed in this system.
After adopting this structure, because the heat exchanger of dress anti-icing fluid in being provided with in the attemperater, not only heat exchange effect is good, the water quick heating in the water tank, and can prevent heat-absorbing plate core and circulation pipe bursting by freezing in the winter time, improve the service life of water heater.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Accompanying drawing is the utility model structural representation.
2 is attemperaters of the present utility model among the figure, the 8th, heat collector, heat-absorbing plate core 7 two ends in the heat collector 8 are communicated with upper circular tube 5, following circulation pipe 1 respectively, the same horizontal level of two circulation pipes in attemperater 2 bottoms inserts in the attemperater 2, and be after following circulation pipe 1 enters attemperater 2, upwards crooked slightly, nose end is positioned at below the neutrality line of attemperater 2, after upper circular tube 5 entered attemperater 2, upwards crooked slightly, the mouth of pipe passed the roof of attemperater 2.Be provided with heat exchanger 4 in the attemperater 2, heat exchanger 4 two ends respectively with insert attemperater 2 in upper circular tube 5, circulation pipe 1 is communicated with down, make heat exchanger 4 and heat-absorbing plate core 7 form a closed system, anti-icing fluid adds back seal cover 3 sealings from the top mouth of pipe of upper circular tube 5.
During use, from intake-outlet 6 with attemperater 2 topped up with water.Anti-icing fluid expanded by heating in the heat-absorbing plate core 7 enters heat exchanger 4 through upper circular tube 5, and the cold anti-icing fluid warp in the heat exchanger 4 circulation pipe 1 down enters heat-absorbing plate core 7, and circulation and so forth can be used the heating of the water in the attemperater.
