Abstract

The utility model discloses a reducer type anti-freezing solar flat plate collector which comprises a collection pipe, a collector casing, a heat absorbing plate, a heat pipe type branch pipe, a heat insulation layer and light through glass arranged on the top. The heat absorbing plate, the heat pipe type branch pipe and the heat insulation layer are sequentially arranged in the collector casing from top to bottom. The upper end of the heat pipe type branch pipe is connected with the collection pipe through a heat conduction block, and the heat collection pipe is arranged on one side of the top end of the heat pipe type branch pipe and is a reducer. The collector has the advantages of being simple in structure, convenient to assemble and disassemble and improves anti-freezing performance through the reducer mode.

Description

A kind of reducing tubular type freeze-proof type solar flat plate heat collector

Technical field

The utility model belongs to solar water heater field, especially the flat-plate collector in solar water heater.

Background technology

Existing flat-plate solar collector 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, by medium in heat collector, overcome water temperature in heating water tank, 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, our design is now a kind of simple in structure, the direct heating type flat plate solar water heater that cost is used 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 utility model provides a kind of reducing tubular type freeze-proof type solar flat plate heat collector, has better anti-freezing property.

Technical scheme: for achieving the above object, the utility model adopts following technology: a kind of reducing tubular type freeze-proof type solar flat plate heat collector, comprise collector, heat collector shell, be located at heat collector shell inner and absorber plate, heat pipe-type arm and heat-insulation layer from arranging successively under upper, and the transparent glass that is located at the top, the upper end of described heat pipe-type arm is connected with collector by heat-conducting block; Described collector is located at heat pipe-type arm top one side, and is reducer pipe.

As preferably, described collector two ends bore is larger, and middle part bore is less.

As preferably, described collector one end diameter is less and be cecum, and other end diameter is large and be openend.

As preferably, also comprise communicating pipe, this communicating pipe is also reducer pipe, two ends diameter is different, and the less one end of diameter is communicated with the cecum of collector.

Beneficial effect: compared with prior art, the utlity model has following advantage: simple in structure, assembly and disassembly is easy, and by reducer pipe mode, improved the anti-freezing property of heat collector.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

Embodiment 1

As shown in Fig. 1 a and 1b, Novel anti-freezing type flat-plate solar collector, comprise heat collector shell, transparent glass, heat-insulation layer and collector plate core, collector plate core is provided with collector, absorber plate, a hot leg pipe, heat-conducting block, absorber plate be arranged on heat pipe arm above, the upper end of heat pipe arm is connected with collector by heat-conducting block, collector one side is cecum, the other end is openend, openend extends to heat collector shell one side outside, and its main feature is that collector is reducer pipe, wherein cecum bore is less, and openend bore is larger.Absorber plate absorbs solar thermal energy, thermal energy conduction is to heat pipe-type arm, the medium top of ascension to arm that be heated in arm, arm top with by heat-conducting block by thermal energy conduction to collector, collector absorbs energy and conducts to the water in collector, by systemic circulation, heat required hot water, arm is heat pipe, can use in subzero, collector is when subzero, start to freeze, due in same environment, freezing speed is the same, what bore was less has first freezed, the meeting that bore is larger has been freezed later, the volume meeting board that tubule increases while first completing is in bassoon, when bassoon in the end completes, by the volume water expanding discharged in collecting system, set herein collecting system pipeline and be the situation while not freezing.

Embodiment 2

As shown in Fig. 2 a and 2b, the difference of the present embodiment and embodiment 1 has only been many a communicating pipe, and the shape of this communicating pipe and collector is the same with structure, is reducer pipe, and the little one end cecum less with the bore of collector of its bore is communicated with.

Embodiment 3

As Fig. 3, as the inferior scheme of selecting, described collector can also be that two ends bore is large, the situation that middle part bore is little.

The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
