Description

The thermostat galvanothermy anti-freezing solar water heater

The utility model relates to a kind of thermostat galvanothermy anti-freezing solar water heater, belongs to heating or heat-exchange device, particularly utilizes the heater field of solar energy.

At present, along with advancing by leaps and bounds and solar utilization technique and production of science and technology, the extensive fusion of life, the application of solar energy has been deep into human lives's every field, and obtained good benefit, solar water heater particularly, big with its pondage, safety, advantages such as expense is low gain great popularity, but the various solar water heater of selling on the market is because last (descending) water pipe is exposed to the open air, and there is not suitable insulation measure, thereby in the winter time, it is not smooth that hot water often appears in the solar water heater that vast northern area uses, and this mainly is because last (descending) water pipe freezes stifled reason.

The purpose of this utility model is the deficiency at above-mentioned solar water heater, for people provide a kind of stifled thermostat galvanothermy anti-freezing solar water heater that can not freeze.

Above-mentioned purpose of the present utility model is to realize like this; it is constant to keep general solar water heater basic composition; promptly comprise attemperater, solar energy heat collection pipe, sunlight reflected plate and upper and lower conduit etc.; upper and lower conduit adopts two section connection structures; epimere is outdoor pipe; adopt a kind of multi-layered composite pipe; this multi-layered composite pipe includes water pipe layer, insulating barrier, electrothermal layer, polyurethane layer and rock wool protective layer; by the control of temperature controller to electrothermal layer; the water temperature of outdoor pipe is controlled in good time; thereby avoided freezing stifled, guaranteed that hot water is unimpeded.

Fig. 2 is multi-layered composite pipe cutaway view of the present utility model (electrothermal layer is the heating wire formula);

Fig. 3 is multi-layered composite pipe cutaway view of the present utility model (electrothermal layer is the electric-heating coatings formula);

Below in conjunction with accompanying drawing structure of the present utility model is elaborated:

With reference to the accompanying drawings 1; 2; 3; be a kind of embodiment of the present utility model; by attemperater [1]; tank bracket; upper and lower conduit [5]; [12] composition such as; on its structure there be characteristics: the heat-insulation layer [14] of attemperater [1] adopts the poly-fat expanded material of pressing; inner bag [23] adopts corrosion resistant plate; non-corrosive; scaling not; solar energy heat collection pipe [2] adopts all-glass vacuum thermal-collecting tube; side at attemperater [1] has; following two horizontal through hole; wherein top one is spillway hole; a threeway [13] is installed on it; the last vertical tube of threeway [13] plays the tonifying Qi effect; following vertical tube plays the overflow effect; keep the water tank water surface elevation; (descending) water pipe of going up of solar water heater is drawn by hole under the side; wherein epimere is the outdoor section [12] of last (descending) water pipe; hypomere is indoor section [5] two sections and connects as one; (descend) water pipe [12] to adopt a kind of multi-layered composite pipe on the open air; its structure is specifically: innermost layer is metallic water pipe [25]; connect as one with indoor (descending) water pipe [5] of going up; cover having thereon successively from inside to outside: interior heat conductive insulating layer [15]; thermostat galvanothermy layer [20]; external insulation layer [16]; polyurethane layer [17] and rock wool protective layer [18]; (outward) heat conductive insulating layer [15] wherein; [16]; have and prevent the function of leaking electricity and conducting heat; the heat of providing is provided thermostat galvanothermy layer [20]; the function of control water temperature; polyurethane layer [17] has the heat of preventing and distributes; heat insulation guarantor's hot merit energy; rock wool protective layer [18] has protecting against shock; anti-aging function; the structure of the thermostat galvanothermy layer of this multi-layered composite pipe can adopt two kinds of forms: it is the electrothermal layer main body that (1) interior heat conductive insulating layer [15] is gone up around one group of heating wire [24]; heating wire [20] is contacted with thermostat probe [21] after lead-in wire [19] is connected with pipe temperature controller [11] outward; on the outer wall of thermostat probe [21] attached to internal layer water pipe [25], temperature controller [11] is connected with power supply.(2) outside interior heat conductive insulating layer [15], be coated with one deck electric-heating coatings [22] and be electrothermal layer [20] main body, respectively there is a lead-out wire [19] on the upper and lower both sides of electric-heating coatings [22], wherein one with after thermostat probe [2] is connected, the temperature controller [11] that two lead-out wires [19] are same and pipe is outer is connected, on the outer wall of thermostat probe [21] attached to internal layer water pipe [25], temperature controller [11] is connected with power supply.

When using this solar water heater, with the indoor metallic water pipe of hypomere with after a control valve [6] is connected, again through threeway and cold water pipe [10], open control valve [6] and cold valves [9] when hot-water line [8] connects cold valves [9] and hot water valve [7] water-filling respectively, close hot water valve [7], finish filling cold water, open hot water valve [7] and control valve [6] when putting hot water, close cold valves [9], if use warm water also can open cold valves [9].

The utility model is owing to (descending) water pipe on the open air of having adopted the MULTILAYER COMPOSITE tubular type, thermostat galvanothermy in it is the interior water temperature of control valve in good time layer by layer, thereby the pipe freezeup phenomenon can not take place, and has anticreep, the aging-resistant advantage is a kind of solar water heater suitable for four seasons.
