Abstract
The invention relates to a solar water heater which can be well combined with the building and has high heat efficiency and low cost. The solar water heater comprises a water inlet pipe, a water outlet pipe and more than one vacuum tube; inner tank with a water inlet branch pipe and a water outlet branch pipe are arranged in the vacuum tube, the water inlet branch pipe is stretched into the bottom part of the inner tank, the water outlet branch pipe is arranged at the top part of the inner inner tank, and the inner tanks are connected between the water inlet pipe and the water outlet pipe in series. The inner tank is a pressurized inner tack, and the two ends surfaces are spherical surfaces so as to bear pressure. The inner tank is made of metal or enamel preferably. In the preferable proposal, the vacuum tube and the inner tank adopt big-caliber products and the inner diameter of the inner tank is more than 70mm preferably. The solar water heater can fully absorb solar energy and change the solar energy into heat energy which can heat the water in the inner tank; a storage water tank is not additionally arranged and the solar water heater has simple structure and can be perfectly combined with the building; in addition, the cost is low, the heat loss of the heater is low, the heat efficiency is high, and the hot water is pressed out by the pressure of the heater; the inner tanks are connected in series, when hot water is used, because the route for push water is long, the situation of hot and cold water mixture is not easily to generate.
Description
Technical field
The present invention relates to a kind of solar water heater, especially a kind of balcony wall-hanging solar water heater.
Background technology
Existing balcony wall-hanging solar water heater is in order to combine with building, and the overwhelming majority all adopts split type, and common split type cost all is higher than monoblock type, and the thermal efficiency is also not as monoblock type.Other has a kind of monoblock type balcony wall-hanging solar water heater, vacuum tube adopts direct insertion, adopt the method heat-obtaining water of coil heat exchanger in the water tank, its shortcoming is that water tank thickness is too thick, can not combine with building well, adopt heat exchanger heat-obtaining water, the thermal efficiency is reduced greatly, have the hidden danger of leaking in addition.
Summary of the invention
The invention provides a kind of solar water heater, can combine with building well, while thermal efficiency height, cost is low.
Described solar water heater comprises water inlet pipe, outlet pipe, more than one vacuum tube, be provided with the inner bag of bringing water arm and exit branch in the vacuum tube, the water inlet arm stretches into the inner bag bottom, and exit branch is located at the inner bag top, and inner bag is connected between water inlet pipe and the outlet pipe.
But inner bag is the pressure-bearing inner bag, and both ends of the surface can be sphere, so that pressure-bearing.Inner bag is preferably metal or enamel material.
As preferred version, vacuum tube and inner bag adopt the heavy caliber product, and the inner bag internal diameter is preferably more than the 70mm.
As improvement of the present invention, vacuum tube inner tube outer surface or inner bag outer surface are covered with coating for selective absorption, with abundant absorption solar energy and change heat energy into, and the water in the heating inner bag; For not applying coating for selective absorption or being covered with the situation of coating for selective absorption at the vacuum tube inner tube outer surface, can between vacuum tube and inner bag, be provided with heat transfer medium, so that heat energy is passed to inner bag quickly, and reduce heat loss.Described heat transfer medium is preferably opening ripple metallic elastic circle, conduction oil or thermal grease conduction.
As another kind of improvement the of the present invention, be provided with the opening ripple metallic elastic circle that outer surface is covered with coating for selective absorption between vacuum tube and the inner bag.At this moment, opening ripple eyelet both can fully absorb solar energy and change heat energy into, can also give inner bag with thermal energy transfer rapidly, improved the thermal efficiency.
The present invention can fully absorb solar energy and change heat energy into, the water in the heating inner bag.Because the inner bag bore is big, thereby need not to join in addition storage tank, simple in structure, can with the building perfect adaptation, cost is low simultaneously; While is owing to the good heat insulating of vacuum tube, and the exhaust outlet heat radiation of the straight-through atmosphere of nothing, thereby the complete machine heat waste is little, thermal efficiency height.But because of the inner bag pressure-bearing, but therefore pressure-bearing goes out hot water.The water inlet arm of inner bag stretches into the bottom, prevents that hot and cold water from mixing water, and exit branch is located at the top, is convenient to exhaust, is connected in series between the inner bag simultaneously, makes that the path of top water is very long when using hot water, is difficult for producing the situation that hot and cold water mixes water.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the enlarged drawing of inner bag among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, solar water heater comprises water inlet pipe 13, outlet pipe 14, more than one vacuum tube 6, header 2, is filled with heat-insulation layer 3 in the header 2.Be provided with the inner bag 5 of bringing water arm 1 and exit branch 4 in the vacuum tube 6, water inlet arm 1 stretches into inner bag 5 bottoms, and exit branch 4 is located at inner bag 5 tops, and inner bag 5 is connected between water inlet pipe 13 and the outlet pipe 14.Inner bag 5 is a stainless steel, internal diameter 70mm, and two ends are sphere, outer surface scribbles coating for selective absorption.Vacuum tube 6 tops link to each other with header 2, and inner bag 5 tops are welded with suspension member 15, by suspension member 15 inner bag 5 are hung over header 2 tops, by side stand 11 gravity are passed on the tailstock 7 again.Automatic exhaust steam valve 8 is located at the highest point of outlet pipe 14, and safety relief valve 12 is located on the water inlet pipe 13.
During use, cold water enters inner bag 5 by water inlet pipe 13, and coating for selective absorption absorbs solar energy and changes heat energy into, the water in the heating inner bag.Cold water enters upwards top hot water of first inner bag bottom by water inlet pipe 13 during water, and hot water flows out from the top of last inner bag.
Difference from Example 1 is: inner bag 5 internal diameters are 80mm, and coating for selective absorption is coated on the outer surface of pipe in the vacuum tube 6, adopt thermostable heat-conductive oil to conduct heat in the vacuum tube 6 between the inner surface of pipe and 5 inner bags.
Difference from Example 2 is: inner bag 5 internal diameters are 100mm, be provided with opening ripple eyelet between pipe and the inner bag 5 in the vacuum tube 6, coating for selective absorption is coated on the outer surface of opening ripple eyelet, the opening ripple metallic elastic circle that outer surface is covered with coating for selective absorption absorbs solar energy and changes heat energy into, the water in the heating inner bag.
