Abstract
The invention discloses a phase change heat-transmission type solar water heater water box. A heat exchanger is arranged inside a liner of the water box, low-temperature phase change media are utilized for heat change, heat change efficiency is improved, and the problem that the low-temperature media freezes is resolved.
Description
One, technical field
The present invention relates to solar energy utilization technique, refer in particular to a kind of inside and be provided with heat exchanger, and utilize the low temperature phase change medium as the solar water heater water tank of heat-conducting medium 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.Flat plate solar water heater uses the mode of indirect more, and heat-conducting medium is thickness relatively, causes heat transfer efficiency not high.
At present existing a plurality of patents about solar water heater water tank, but the lower heat-conducting medium of boiling point can be used, and install the water tank discovery as yet that the jet pipe accelerating medium flows additional.Below list several existing relevant patents:
(application number: 99229690.0) propose a kind of solar water heater water tank, its inner water tank is divided into two parts that do not communicate by water-stop sheet to patent " novel solar water heater water tank ", and conducts heat by water-stop sheet.
(application number: 200720037641.X) propose a kind of solar water heater water tank, this device is provided with an inner bag to patent " novel solar water heater water tank " in water tank, pure water is housed as heat transfer medium in the inner bag, the drinking water of heating water tank outside.
For address this problem can seek a kind of boiling point at the low temperature phase change liquid below 100 degrees centigrade as heat-conducting medium, becoming the sensible heat heat transfer mode is that latent heat conducts heat, and improves the heat transfer rate.
Three, summary of the invention
For solving existing flat plate solar water heater heat-conducting medium thickness, heat exchange efficiency is low, and low temperature easily freezes and the high problem of jacket water tank heat loss, proposes following solution:
The present invention proposes a kind of phase-change heat transfer formula solar water heater water tank, and its structure comprises: heat-insulation layer, inner bag, outlet pipe, water inlet pipe, heat exchanger, medium inlet pipe, medium go out pipe, blind flange.Heat-insulation layer adopts the polyurethane foam material insulation, and thickness is at least 5 centimetres.Inner bag is equipped with outlet pipe, water inlet pipe, heat exchanger, medium inlet pipe and medium and goes out pipe by the blind flange shutoff on the blind flange, its medium inlet pipe and medium go out pipe and be positioned at heat exchanger inside.The effluent pipe mouth position is higher than water inlet pipe mouth.Heat exchanger places the inside of inner bag, its volume is more than or equal to the volume of endothermic tube in the heat collector, heat exchanger goes out the endothermic tube UNICOM of pipe and heat collector by medium inlet pipe and medium, form the circulatory flow of a sealing, medium is in this runner internal flow, and the amount of medium is identical with heat collector endothermic tube volume.Medium adopts the innocuous substance of boiling point between 30 to 60 degrees centigrade, charge into medium before, circulatory flow inside vacuumizes, vacuum is in 0.03 to 0.05 MPa.The medium inlet pipe mouth of pipe is near the heat exchanger top, and medium goes out the mouth of pipe near the heat exchanger bottom.The position at solar thermal collector top is lower than at least 0.5 meter of heat exchanger bottom.This water tank can also add the auxiliary electrical heating arrangements.
Above technical scheme has three advantages: heat exchanger is placed inner bag inside, make heat all pass to water in the inner bag, reduced thermal loss; Adopt the low temperature phase change medium, the shortcoming of having avoided heat-conducting medium thickness and low temperature easily to freeze; The heat-exchange system sealing does not have leakage, has avoided the problem of medium water clock.
Four, description of drawings
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is the generalized section of this device.
The position of marking is respectively among the figure: 1, heat-insulation layer; 2, inner bag; 3, outlet pipe; 4, water inlet pipe; 5, heat exchanger; 6, medium inlet pipe; 7, medium goes out pipe; 8, blind flange.
Five, the specific embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Solar water heater water tank outside is connected to solar thermal collector, and heat exchanger 5 goes out the circulatory flow that pipe 7 and the endothermic tube of solar thermal collector constitute sealing by medium inlet pipe 6 and medium, and inside is filled with boiling point at 30 to 60 degrees centigrade heat-conducting medium.Heat exchanger 5 places the inside of inner bag 2.Solar thermal collector absorbs solar energy, convert heat energy to, heat-conducting medium ebuillition of heated in the endothermic tube is vaporized, the heat-conducting medium of gaseous state under pressure, enter heat exchanger 5 from medium inlet pipe 6 rapidly, heat release condensation on inwall, and compile to go out pipe 7 from medium and be back in the heat collector endothermic tube, a circulation finished.Water in the inner bag 2 absorbs heat from heat exchanger, becomes hot water.Outlet pipe 3 is used for heat-obtaining water, and water inlet pipe 4 is used for mending cold water.
