Technical field

The utility model relates to technical field of solar water heaters, particularly press-bearing water tank of solar energy water heater.

Background technology

At present, domestic press-bearing water tank of solar energy water heater adopts heat-tube vacuum collector mostly, its fluid passage is smaller, just require to have the good hot property of seeking, if directly water is as medium, system can cause hot property to descend in long-play because of the influence of incrustation scale, so general now hope is opened use with thermal cycle pipeline and the line isolation that is heated water, just in the water tank or increase heat-exchanger rig outward, yet, generally mostly be plate-type exchanger at the outside heat-exchanger rig that increases of water tank, this heat exchanger cost is higher; Built-in heat exchanger mostly is spirality copper pipe or carbon steel enamel pipe, and this structural repair difficulty, for the convenience of keeping in repair must be added some structures; Make the cisten mechanism complexity equally.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, can solve the press-bearing water tank water lines and separate with the heat cycles pipeline, realizes the press-bearing water tank of indirect heat exchange problem.

The utility model is that the technical scheme that addresses the above problem employing is a kind of press-bearing water tank of solar energy water heater, comprise the end socket that shell, heat-insulation layer, inner core and heat exchange joint, inner core have barrel and be tightly connected with barrel, the inner core outside is coating heat-insulation layer, the heat-insulation layer outside is coating shell, have water inlet and delivery port on the shell, its innovative point is:

A, inner core are provided with at interval tube, and the end socket at tube and inner core two ends is tightly connected at interval;

Water inlet that has on b, the shell and delivery port pass the inner core barrel and lead directly in the tube of interval;

Have the medium inlet hole and media outlet hole and the heat exchange joint that feed the mezzanine space between interval tube and the inner core on c, the shell.

Described shell is provided with and passes heat-insulation layer, inner core leads directly to into the decompression valve port in the tube of interval.

Described shell is provided with row's heat exchange joint vertically.

Described interval tube is connected with inner core two ends end socket welded seal.

Described shell is provided with the electrical heating connecting hole that leads directly in the tube of interval.Described shell is provided with the magnesium rod connecting hole that leads directly in the tube of interval.

Press-bearing water tank of solar energy water heater of the present utility model, owing in inner core, increased tube at interval, we utilize the mezzanine space that forms between interval tube and the former inner tube wall to charge into medium, the heat exchange joint is directly to feed mezzanine space, can drive heat by medium like this, heating is the interior water of tube at interval, the realization water lines is separated with the heat cycles pipeline, reach the purpose of indirect heat exchange, and the mezzanine space that has the heat exchange joint and charge into medium is a sealed space, be the space that isolates with the water route, do not have the pollution of incrustation scale etc., solved the problem that incrustation scale influences hot property.Therefore, press-bearing water tank of solar energy water heater of the present utility model is simple in structure, stable performance.Because be to bear hydraulic pressure in the tube at interval, bearing capacity is big, realized the whole bearing operation of water tank, the demand of piece-rate system indirect heat exchange.

Description of drawings

Fig. 1 is the structural representation of the utility model press-bearing water tank of solar energy water heater.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in detail the utility model.

Referring to Fig. 1, a kind of solar water heater double-layered pressure-bearing water tank, comprise the end socket 3-2 that shell 1, heat-insulation layer 4, inner core 3 and heat exchange joint 5, inner core 3 have barrel 3-1 and be tightly connected with barrel 3-1, inner core 3 outsides are coating heat-insulation layer 4, heat-insulation layer 4 outsides are coating shell 1, water inlet 7 that has on the shell 1 and delivery port 8, its innovative point is:

A, inner core 3 are provided with tube 2 at interval, and the end socket 3-2 at interval tube 2 and inner core 3 two ends is tightly connected;

Water inlet 7 that has on b, the shell 1 and delivery port 8 pass inner core 3 barrels and lead directly in the interval tube 2;

Have the medium inlet hole 12 and media outlet hole 13 and the heat exchange joint 5 that feed the mezzanine space 11 between interval tube 2 and the inner core 3 on c, the shell 1.Owing in inner core 3, increased tube 2 at interval, form mezzanine space 11 between the barrel of feasible tube 2 at interval and inner core 3, mezzanine space 11 has heat exchange joint 5, pass through medium inlet hole 12 injected medias in the mezzanine space 11, the air that discharge in the mezzanine space 11 in media outlet hole 13, the heat that the solar energy that heat exchange joint 5 brings provides is passed to medium rapidly, and medium conducts heat to being heated water by the barrel of tube 2 at interval, this structure, heat exchange area is big, and the passage that is heated water is also big, has increased the bearing capacity of water tank, realized whole pressure-bearing, indirect heat exchange.

In order to guarantee press-bearing water tank of solar energy water heater safety in use, and further increase the heat exchange effect referring to Fig. 1, the further inventive point of the utility model is that shell 1 is provided with and passes heat-insulation layer 4, inner core 3 and lead directly to into the decompression valve port 6 in the tube 2 at interval.Described shell 1 is provided with row's heat exchange joint 5 vertically.Described interval tube 2 is connected with inner core 3 two ends end socket 3-2 welded seals.

Referring to Fig. 1, can obtain round-the-clock use in order to make the utility model, promptly when cloudy day of solar energy deficiency or winter temperature are low, also can use, described shell 1 is provided with the electrical heating connecting hole 9 that leads directly in the tube 2 at interval.

Because the water tank at interval water in the tube 2 can produce incrustation scale for a long time in heating constantly in the use unavoidably, prevents the generation of incrustation scale in order to guarantee the heat exchange effect, described shell 1 is provided with the magnesium rod connecting hole 10 that leads directly in the tube 2 at interval.

Referring to Fig. 1, the utility model on the make can be at first with the end socket 3-2 welding at tube 2 and inner core 3 two ends at interval, then, after welding inner core barrel 3-1 again and guaranteeing the sealing of soldering opening, coat heat-insulation layer 4 and shell 1 each hole of last processing etc. again, since simple in structure, process also very convenient, satisfied the whole pressure-bearing of water tank, the function of indirect heat exchange, water enters from the water inlet 7 of press-bearing water tank in the use, is full of in the interval tube 2; At medium import 12 injected medias, because mezzanine space 11 is spaces of a sealing, therefore must there be media outlet hole 13 to discharge air, after injected media is an amount of, two mouthfuls can be shut, the row's heat exchange joint 5 that feeds mezzanine space this moment is directly passed to medium with the heat of solar energy, medium is heated, and medium conducts heat the barrel of heat by interval tube 2 to the water in the tube rapidly, has realized indirect heat exchange, when water temperature is too high, can open safety relief valves 6 that feed in the interval tube 2 reduces pressure, guarantee the safety of press-bearing water tank, the user need use hot water can open delivery port 8 at any time, can obtain hot water.
