Abstract

The invention discloses an anti-freeze flat-plate solar water heater which is characterized in that a heat exchange coil and a heat collection tube cavity are sealed and can bear certain pressure, and the cavity is filled with heat exchange working fluid. The heat exchange coil is positioned in a thermal insulation water tank; the heat collection tube and a heat collection plate are combined to realize the function of heat absorption and transfer. According to the invention, suitable heat exchange working fluid is selected, which ensures that the heat exchange working fluid does not condense at night in winter, and the heat exchange working fluid evaporates and condenses quickly, and therefore the water heater disclosed by the invention has the characteristics of anti-freeze property and is quick to warm up.

Description

Antifreeze flat plate solar water heater
One, technical field
The present invention relates to solar energy utilization technique, refer in particular to a kind of with flat plate solar water heater the thermal-collecting tube sealing and charge into heat-exchange working medium, the water heater that the water through heat exchange coil and attemperater inside carries out heat exchange.
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 through the flat plate collector thermal-collecting tube is sealed and charge into heat-exchange working medium, carry out the water heater of heat exchange through heat exchange coil and attemperater and find as yet to apply for a patent.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 present invention proposes a kind of antifreeze flat plate solar water heater.This water heater is made up of attemperater, heat exchange coil, thermal-collecting tube, the thermal-arrest plate that is coated with coating for selective absorption, insulation shell, transparent cover plate etc.Wherein heat exchange coil and thermal-collecting tube constitute the integral body of sealing, charge into heat-exchange working medium in the pipe.Working medium selects for use boiling point about 50 ℃, and freezing point is below-30 ℃, nontoxic non-flammable liquid substance (for example trichlorine three richnesses are for ethane, but are not limited thereto).The integral body that heat exchange coil and thermal-collecting tube constitute must can be born certain pressure, guarantees can not overflow after the heat-exchange working medium endothermic gasification.Heat exchange coil is coiled in the attemperater, and thermal-collecting tube links together through welding or other processing modes and thermal-arrest plate.In insulation shell needs the part that thermal-collecting tube passes in and out attemperater also is wrapped in.The attemperater water inlet is furnished with magnetic valve and temperature sensor, and the water temperature and the water yield in the control attemperater guarantee the stable of water temperature.Because the freezing point of heat-exchange working medium is very low, even still can keep liquid in the winter time the night of severe cold, therefore can not influence and use daytime, and it is fast to have a programming rate, the advantage that is difficult for freezing.Heat exchange coil guarantees that in the coiling of attemperater inside spin heat exchange is abundant.Thermal-collecting tube on the thermal-arrest plate for S shape curves, make heat-exchange working medium gasification with abundant heat absorption.
Four, description of drawings
Below in conjunction with accompanying drawing, the present invention is described further.
Fig. 1 is this schematic representation of apparatus.
The position of marking is respectively among the figure: 1, water inlet; 2, attemperater; 3, thermal-collecting tube; 4, heat exchange coil; 5, delivery port; 6, insulation shell; 7, thermal-arrest plate.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described further.
The seal chamber that heat exchange coil 4 and thermal-collecting tube 3 constitute can bearing certain pressure, guarantees not overflow after the heat-exchange working medium gasification.Thermal-arrest plate 7 is a heat energy with transform light energy during water heater working, passes to thermal-collecting tube 3, and the heat-exchange working medium endothermic gasification in the thermal-collecting tube 3 also gets into heat exchange coil 4.In heat exchange coil 4, heat-exchange working medium condensation heat release raises water temperature the water in the heat transferred attemperater.Condensed heat-exchange working medium is back to thermal-collecting tube 3 and continues heat absorption.Water inlet 1 is furnished with magnetic valve, is furnished with temperature sensor in the attemperater 2, through the regulating tank water yield, guarantees water temperature in the water tank.Because the heat-exchange working medium freezing point is low, be difficult for night freezing, even and freeze because the principle of expanding with heat and contract with cold can the bursting by freezing endothermic tube yet, guaranteed the safety of heat collector microthermal climate.
