The water heater employs an absorber plateas an absorber body, and a coiled bent pipe is welded on the back of the water heater; a heating liner is arranged inside a heat-preservation water tank; the inlet nozzle is mounted in the liner; and the liner is connected with the absorber body through a pipeline and filled with a heat conduction medium with the boiling point of about 30 DEG C. The water heater is high in thermal reaction speed and is higher in efficiency and resistant to low temperatures at a low radiation degree.

Description

A kind of coil pipe type flat plate solar water heater that has jet pipe

One, technical field

The present invention relates to solar energy utilization technique; Refer in particular to a kind of coil pipe type flat plate solar water heater that has jet pipe; This water heater possesses coil pipe type absorber and water tank heating inner container; Adopt the material of boiling point about 30 ℃ as heat-conducting medium, jet pipe is housed in the heating inner container can quickens flowing of heat-conducting medium.

Two, background technology

At solar energy heat utilization field, the multiple matured product of vacuum tube water heater and dull and stereotyped water heater has appearred comprising in solar water heater, and the plate type solar water heater is opened up markets rapidly with its longer service life and easy installation method.But, when temperature is low, especially freeze easily night, so still can not adapt to the northern cold cold weather because bigger, hot water programming rate of heat loss and amplitude are poorer slightly than vacuum tube water heater.

At present existing a plurality of patents about the plate type solar water heater, but its heat-conducting medium all is to utilize high boiling organic matter such as ethylene glycol to mix water as heat-conducting medium, and thermal response speed is very slow.Below list several existing related patent U.S. Patent No.:

(application number: 99218284.0) propose a kind of water heater, its absorber is that two metallic plates constitute to patent " efficient freeze proof plate type solar water heater ", is full of water in the gap between two metallic plates, and the absorber upper surface is coated with coating for selective absorption.Because the water yield in the absorber gap is fewer, when water freezing expanded, Volume Changes was within the regime of elastic deformation of metallic plate, and can guarantee can be not freezing.

Patent " anti-freezing type flat plate solar water heater " (application number: 200720174980.2) propose a kind of anti-freezing type flat plate solar water heater; It is in water storage tank and dull and stereotyped heater box; Thermal energy transfer device and heat energy endothermic tube, absorber plate are housed, install freeze proof medium in the heat energy endothermic tube additional.

Three, summary of the invention

The utility model proposes a kind of coil pipe type flat plate solar water heater that has jet pipe, and this water heater is made up of coil pipe type flat-plate solar collector, attemperater and pipeline.Wherein collector structure comprises: insulation shell, transparent cover plate and absorber, and absorber is made up of snake bend and absorber plate.The attemperater structure comprises: the outer bucket of insulation, heating inner container, import jet pipe, outlet.The runner direction level of heat collector absorber snake bend is welded on the absorber plate back, inner chamber and heating inner container UNICOM, and be filled with boiling point about 30 ℃, freezing point is lower than-40 ℃ heat-conducting medium.An absorber plate side external surface on the sunny side is coated with coating for selective absorption.The outer bucket of the insulation of attemperater surrounds a cavity with heating inner container, and inside fills water to be heated.Heating inner container constitutes for thin corrosion resistant plate, and through pipeline and heat collector snake bend.The heat collector outlet is on heat collector top, and import is in the heat collector bottom, and heating inner container import nozzle position is high, and near the inner bag top, the outlet position is low, near the inner bag bottom.The import jet pipe is the scaling type jet pipe.On near the pipeline of inner bag outlet a check-valves is housed, is used to control the amount of the heat-conducting medium of getting back to heat collector.

Four, description of drawings

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

The position of marking is respectively among the figure: 1, heat collector; 2, attemperater; 3, heat collector outlet; 4, heat collector import; 5, snake bend; 6, absorber plate; 7, insulation shell; 8, transparent cover plate; 9, the outer bucket of insulation; 10, heating inner container; 11, import jet pipe; 12, outlet; 13, check-valves.

Five, the specific embodiment

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

Absorber plate 6 surfaces are coated with coating for selective absorption, absorb the daylight heating up.Snake bend 5 inner heat-conducting medium heat absorptions are vaporized, and get into heating inner container 10 from heat collector outlet 3 through pipeline.The medium of vaporization during through import jet pipe 11 speed improve, the stagnation phenomenon takes place on wall of inner container, further heat up condensation heat release subsequently, the water that heating water tank is interior.Condensed heat-conducting medium collects in the bottom of heating inner container 10 and flows back to heat collector import 4 from outlet 12 through pipeline.When water tank temperature is too high, can close check-valves 13, stop the backflow of heat-conducting medium, interrupt circulation.
