Abstract
The invention discloses an antifreeze flat-plate solar water heater which comprises a heat-insulation water tank and a flat-plate solar heat collector. The flat-plate solar heat collector is arranged below the heat-insulation water tank and comprises a heat collector shell, plate core headers, plate core branch pipes, a heat absorption plate and a heat-insulation layer, the plate core headers, the plate core branch pipes, the heat absorption plate and the heat-insulation layer are arranged in the heat collector shell, the plate core branch pipes are arranged side by side, two ends of each plate core branch pipe are respectively connected with the plate core headers so that the plate core branch pipes can be gathered, and the diameter of each plate core header is larger than that of each plate core branch pipe; the heat absorption plate is arranged on the outer sides of the plate core branch pipes and is arranged on the other sides of the plate core branch pipes; solid rods are further arranged in the plate core headers; the plate core headers in the flat-plate solar heat collector are communicated with the heat-insulation water tank, so that water circulation can be formed. The antifreeze flat-plate solar water heater has the advantages that when the water heater is frozen in winter, ice extends from the plate core branch pipes towards the plate core headers, the plate core headers extend from the lower end of the water heater towards the upper end of the water heater, accordingly, frozen and expanded water can be squeezed into the heat-insulation water tank, and frost cracking of flow channels can be prevented.
Description
Technical field
The invention belongs to solar water heater field, relate in particular to the solar water heater with antifreezing function.
Background technology
Prior art flat plate solar water heater is divided into direct heating type and indirect heating type, heat exchanger in indirect heating type flat plate solar water heater water tank is connected with heat collector, overcome water temperature in heating water tank by medium in heat collector, one of them feature of medium is anti-freeze properties, can overcome the freeze proof problem of heat collector of ice period, such method major defect is complex structure, cost is higher, anti-icing fluid need supplement and change, make this product be difficult to promote the use of, another kind is direct heating type, flat-plate solar collector can not be freeze proof, this scheme is only applicable to tabetisol district and uses, we design a kind of simple in structure now, the direct heating type flat plate solar water heater that cost uses in ice period compared with low energy.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of anti-freezing type flat plate solar water heater, can avoid heat collector due to freezing and expansion bursting by freezing runner, ensured the frost resistance of solar thermal collector.
Technical scheme: for achieving the above object, the present invention adopts following technology: a kind of anti-freezing type flat plate solar water heater, comprise attemperater and the flat-plate solar collector that is located at attemperater below, described flat-plate solar collector, comprise heat collector shell, and be located at plate core collector, plate core arm, absorber plate and the heat-insulation layer in heat collector shell, and described plate core arm is arranged side by side and two ends are connected with respectively plate core collector and collect, and the diameter of described plate core collector is greater than plate core arm diameter; Described absorber plate is located at the outside of plate core arm, and described absorber plate is located at the opposite side of plate core arm; In described plate core collector, be also provided with solid bar; Plate core collector in described flat-plate solar collector is communicated with attemperater, forms water circulation.
As preferably, described solid bar is truncated cone, and compare great one end, cross section down.
Beneficial effect: compared with prior art, the present invention has the following advantages: when water heater ice up in winter of the present invention, the slave plate core arm that freezes extends toward plate core collector, and plate core collector extends from lower end toward upper end, thereby the water of freezing and expansion can be clamp-oned to attemperater, thereby prevent runner bursting by freezing.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of anti-freezing type flat plate solar water heater, comprise attemperater and the flat-plate solar collector that is located at attemperater below, described flat-plate solar collector, comprise heat collector shell, and be located at plate core collector, plate core arm, absorber plate and the heat-insulation layer in heat collector shell, and described plate core arm is arranged side by side and two ends are connected with respectively plate core collector and collect, and the diameter of described plate core collector is greater than plate core arm diameter; Described absorber plate is located at the outside of plate core arm, and described absorber plate is located at the opposite side of plate core arm; In described plate core collector, be also provided with solid bar, and this solid bar lower thick upper thin; Plate core collector in described flat-plate solar collector is communicated with attemperater, forms water circulation.
In the time that system has been poured water, in daylighting process, can be by the water in the water circulation heating and thermal insulation water tank in flat-plate solar collector and attemperater, when in ice period, temperature is lower than 0 degree, plate core arm on collector plate core starts to be freezed by mediad two ends, plate core collector on collector plate core freezes simultaneously, because environment temperature is identical, so freezing speed is also identical, because the caliber of plate core header of thermal collector is larger, the caliber of plate core arm is less, so collector plate core arm has first freezed, and the water of the volume expanding owing to freezing in plate core arm is entered in plate core collector, ensure that plate core arm is not by bursting by freezing.The upper end of plate core collector is connected with attemperater, in plate core collector, lower end is provided with solid bar, compare great bottom, liquid in pipe partial cross section top is less, first heat-collecting plate core collector bottom can freeze, top is freezed slower, on heat-collecting plate core collector vertical plane, from bottom to top freeze in proper order, until in attemperater, like this until complete plate core header of thermal collector and freezed, the volume expanding in the time freezing due to the water in collector plate core runner is discharged in attemperater, thereby can be because of expansion bursting by freezing runner, heat collector is damaged by frost, ensure the frost resistance of flat-plate solar collector.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
