Abstract

The utility model relates to an assembled solar water heater. The water inlet and the water outlet of the heat-exchange water tank of the water heater are provided with magnetizing joints. A heat pipe and the water tank are connected by adopting a plug-in type, and are sealed by an O-shaped sealing ring. The condensing section of the heat pipe is one third or one fourth of the total length of the heat pipe, and the working medium of the heat pipe is 15% to 35% of the total volume of the heat pipe. The utility model has the advantages of simple structure, convenient maintenance, and high heat efficiency. The utility model is easy for a plurality of series connected combinations.

Description

High efficiency combined solar water heater

The utility model belongs to solar thermal energy and utilizes manufacturing field of equipment.

Present all kinds of solar water heaters all exist the thermal efficiency low to some extent, and water quality is not high, inconvenient maintenance, and large tracts of land needs special concentrated water tank when using, and pipeline connects shortcomings such as complexity.

The purpose of this utility model is a kind of novel solar water heater of design, makes it to overcome the above shortcoming of prior art, and has higher all-day efficiency, easy to maintenance, characteristics cheaply.

The purpose of this utility model is to realize by following means.

On the combined solar water heater of forming by heat collector tube plate, heat exchange water tank etc., be provided with the magnetization joint in the import and the outlet of heat exchange water tank; Heat pipe condenser section accounts for 1/3～1/4 of heat pipe length overall, and the filling weight of working medium accounts for 15%～35% of heat pipe cumulative volume in the heat pipe; Heat pipe adopts plug-in type to connect with water tank, with the sealing of O RunddichtringO.

After having adopted design as above, be equipped with the magnetization joint, water is magnetized, improved water quality, avoided on the one hand producing incrustation scale and the thermal efficiency being reduced, help user's skin health on the other hand on the heat pipe condenser section surface in the import and export of water.The control of the length of opposite heat tube condensation segment and the filling weight of working medium has improved the microcirculation condition that is heated water in the water tank, and the thermal efficiency is increased.Heat pipe is inserted in the water tank, rather than resembles and be welded on the water tank the prior art, makes easy to maintenance.

Description of drawings is as follows

Fig. 1 is a side view of the present utility model.

Fig. 2 is the longitudinal sectional view of Fig. 1.

Fig. 3 is the transverse sectional view of Fig. 1.

Fig. 4 is the utility model heat pipe and water tank connection diagram.

Fig. 5 is that the utility model is used in combination figure.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

In Fig. 1 to Fig. 3, the 1st, heat collector tube plate, the 2nd, heat exchange water tank, the 3rd, import magnetization joint, the 4th, outlet magnetization joint, 8 for connecting firmly the support on the thermal-arrest plate, and 5 is the thin-belt type heat pipe, and 10 is heat pipe condenser section, 11 are the water inlet ball-cock assembly, 12 is the float intake pipe, the 13rd, and heat-insulation layer, the 7th, post the reflective inclined-plane about 20 of light reflecting membrane is spent.What phase-change working substance adopted is acetone, and it is good that its declared content accounts for 15%～35% of heat pipe cumulative volume: it is good that heat pipe condenser section 10 accounts for 1/3～1/4 of heat pipe 5 length overalls.

Among Fig. 4,6 is the O RunddichtringO, and swivel nut and nut are connected in the condensation segment of heat pipe 5 on the water tank hermetically.

Fig. 5 is the situation that 3 the utility model tandem compounds use, and three water heaters are filled with water, and after the heat pipe on separately with it carried out heat exchange, each water tank upper all was a hot water, and during water, the water heater water intaking by the left side can guarantee that the water of being got all is hot water.When wintry weather is terribly cold, can in the end increase further raising water temperature of electric heater 9 in a water heater.

Clearly, the temperature of hot water is relevant with the water tank volume according to shining area with heat pipe, under certain conditions, adopts the small size water tank of multistage combination, and the utility model can be made solar boiler, to satisfy many-sided needs.
