Described little water tank 8 is fixed on the support 1, and the heat radiation of energy-collecting pipe 2 or heat transfer end are inserted in the little water tank 8, and water to be heated direct and that little water tank is interior carries out heat exchange;

Described storage tank 12 is communicated with described little water tank 8 by pipeline, by the form that water circulates, the version that storage tank 12 is communicated with little water tank 8 can be divided into the continuous circulating structure that the intermittent discharge of temperature-sensing valve 11 formula structure and no temperature-sensing valve 11 are arranged in pipeline;

Described automatic sun-tracking machine is made up of solar hour angle tracking means 14 and solar declination angle tracking unit 15, the support 1 of described concentrator is installed on the solar declination angle tracking unit 15, thereby makes condenser 3 and the energy-collecting pipe 2 installed on the support 1 realize following the tracks of sun's motion.

2, described little water tank 8 respectively leaves an ozzle on the position on the upper side and on the lower side at it, and be connected to flexible pipe on each ozzle, the flexible pipe that promptly is connected to the top ozzle is a top hose 9, and the flexible pipe that is connected to the bottom water nozzle is a bottom hose 10, so just can satisfy little water tank when motion, flexible pipe also can move with it.

3, described storage tank 12 is intermittent discharge formula structures with the connectivity structure of little water tank 8, top hose 9 on the little water tank 8 is communicated with storage tank 12, on the pipeline at bottom hose 10 or top hose 9 places, insert temperature-sensing valve 11, when making the interior water of little water tank be heated to the temperature of temperature-sensing valve 11 settings, temperature-sensing valve 11 is opened, cold water enters little water tank 8 from bottom hose 10, hot water or boiling water flow out from top hose 9, enter storage tank 12, when the water temperature in the little water tank 8 was lower than the temperature of temperature-sensing valve 11 settings, temperature-sensing valve 11 cut out, and water inlet and water outlet all stop.

4, described storage tank 12 is continuous circulating structures with the connectivity structure of little water tank 8.Top hose 9 on the little water tank 8 and bottom hose 10 all are communicated with storage tank 12, utilize the thermosiphon principle of liquid, make water at low temperature and the high-temperature water in the little water tank 8 in the storage tank 12 form natural convection loop, for Natural Circulation can normally be moved, will make the liquid level of storage tank 12 be higher than the liquid level of little water tank 8.

The utlity model has following advantage and effect:

1, the utility model can make energy-collecting pipe concentrate and absorb and the conduction heat owing to adopt the heating principle of tracing collection, can reduce like this link of heat loss can be in the winter time or extremely frigid zones can be rapidly use for the user cold water is boiled;

2, the utility model is rational in infrastructure, and is simple and easy, is easy to cheap for manufacturing costly, is convenient to promote the use of, and especially more can show its effect at extremely frigid zones;

3, structure of the present utility model is easy to install, and uses, and safeguards, repairs.

The face of accompanying drawing is described as follows:

Figure 1A is a front view of the present utility model

Figure 1B is a vertical view of the present utility model

Fig. 2 is the front view of the utility model the 2nd embodiment

Be described further below in conjunction with drawings and Examples:

By Figure 1A, Figure 1B as can be known, this figure is the utility model the 1st embodiment, wherein, condenser 3,3 ' be parabola cylinder mirror condenser, the two ends of condenser 3 coaxial line be fixed with

minor axis

17,5, condenser 3 ' the two ends coaxial line be fixed with minor axis 17 ', 5 ', each minor axis all is contained in the hole of support 1, at

minor axis

17,5,17 ', 5 ' on torsion spring 18 is housed successively, 6,18 ', 6 ', under the torsion spring torsional interaction, make the

limited block
