Abstract
The utility model discloses a snakelike-runner panel solar water heater with a spray pipe. According to the water heater, a cuboidal metal box of which the inner cavity is separated into a snakelike runner is used as a heat absorbing body, a heat-insulating water tank is internally provided with a heating inner container which is internally provided with an inlet spray pipe, and the inner container is in pipeline connection with the heat absorbing body, and is filled with heat-conducting media with the boiling point at 30 DEG C. The water heater disclosed by the utility model has the characteristics of high thermal reaction speed, higher efficiency under low radiation condition and low temperature resistance.
Description
One, technical field
The present invention relates to solar energy utilization technique, refer in particular to a kind of serpentine flow path flat plate solar water heater with jet pipe, absorber and the water tank heating inner container of the standby serpentine flow path of this water heater, adopt the material of boiling point about 30 ℃ as heat-conducting medium, jet pipe is housed in the heating inner container can accelerates flowing of heat-conducting medium.
Two, background technology
At solar energy heat utilization field, the multiple matured product of vacuum tube water heater and flat 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 because larger, the hot water programming rate of heat loss and Amplitude Ratio vacuum tube water heater are slightly poor, when temperature is low, especially easily freeze night, so still can not adapt to northern cold climate.
Present existing a plurality of patents about the plate type solar water heater, but its heat-conducting medium all is to utilize the 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 Patents:
(application number: 99218284.0) propose a kind of water heater, its absorber is that two metallic plates consist of 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 flat water heater casing, heat energy transmitter 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 purpose of this utility model is to improve the temperature that collecting plate mouth place heat-conducting medium, and improve heat-conducting medium enter heating inner container the time flow velocity, improve pressure differential, strengthen heat conduction, thereby improve the overall thermal efficient of system.
The utility model proposes a kind of serpentine flow path flat plate solar water heater with jet pipe, this water heater is made of serpentine flow path flat-plate solar collector, attemperater and pipeline.Wherein collector structure comprises: insulation shell, transparent cover plate and absorber, and absorber is comprised of heat absorption body wall and the inner serpentine flow path that is divided into.The attemperater structure comprises: insulation outer barrel, heating inner container, import jet pipe, outlet.The heat collector absorber is the flat cuboid that is welded into by metal sheet, and inside is divided into serpentine flow path with the long-bar metal sheet, runner direction level, and be filled with boiling point about 30 ℃, freezing point is lower than-40 ℃ heat-conducting medium.An absorber on the sunny side side external surface is coated with coating for selective absorption.The insulation outer barrel of attemperater and heating inner container surround a cavity, and inside fills water to be heated.Heating inner container is that thin corrosion resistant plate consists of, and by pipeline and heat collector absorber UNICOM.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 exit 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 for the amount that the heat-conducting medium of heat collector is got back in control.
Beneficial effect of the present utility model is: the intensification so that heat-conducting medium absorbs heat in flow process always by serpentine flow path, and before arriving the collecting plate outlet, reach the boiling point vaporization; The jet pipe of heating inner container inside can accelerate flowing of air-flow, so that a high speed is arranged during air stream outlet, and the stagnation throttling occurs at the wall of heating inner container, and improve pressure and temperature.
Four, description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the overall schematic of this device.
Fig. 2 is the profile of this device heat collector.
Fig. 3 is heat collector A-A cutaway view.
Fig. 4 is the cutaway view of attemperater.
The position of marking is respectively among the figure: 1, heat collector; 2, attemperater; 3, heat collector outlet; 4, insulation shell; 5, heat absorption body wall; 6, serpentine flow path; 7, heat collector import; 8, transparent cover plate; 9, insulation outer barrel; 10, heating inner container; 11, import jet pipe; 12, inner bag outlet; 13, check-valves.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
The selective absorber coatings of absorber plated surface absorbs the daylight heating, and heat absorption body wall 5 heats up.The heat-conducting medium of absorber inside heat absorption vaporization, and enter heating inner container 10 from heat collector outlet 3 by pipeline.The stagnation phenomenon occurs at wall of inner container in the medium of vaporization Speed improving during by import jet pipe 11, further heats up subsequently condensation heat release, 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 7 from inner bag 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.
