Description

A kind of directly-heated Split type wall-hanging solar water heater

Technical field:

The present invention relates to a kind of apparatus for heating water by solar energy, especially a kind of directly-heated Split type wall-hanging solar water heater.

Technical background:

At present, the glass tube with vacuum solar water heater technology of installing on roof is ripe, because its water tank and heat collector disjunctor, and heat collector is changeable, and its mounting condition is often unrestricted.From the daylighting time, the time is relatively long mutually compared with wall-hanging solar, and its hot water effect is satisfactory.But not every user is applicable to such solar energy is installed, particularly high-rise building user is more not suitable for, and therefore people consider wall-hanging solar.

Because wall-hanging solar is subject to the restriction of the condition such as installing space and load-bearing, existing wall-hanging solar water heater mostly adopts heat collector and water tank to divide and is arranged, between heat collector and water tank, utilize super heat conduction, adopt the solar water heater efficiency of this technology low, and be prone to the faults such as superconducting fluid leakage.

For overcoming the deficiency of above water heater, the release one new solution patent No. is: this technology of ZL200620024192.0 has obtained certain good effect, but it also exists deficiency.

Also want energy pressure-bearing, also more complicated of the high manufacturing process of cost if be provided with pressure-bearing inner liner, that corresponding water tank in thermal-collecting tube; If adopt directly-heated static pressure, due to water tank in room, can arrange height-limited, feel under the weather by the static pressure unable people that spray water at bathing tap; Have again, cold point of connecting leg in incubation chamber divides on connecting leg employing plastics PPR pipe and punches, inlays water injection pipe and the communicating pipe socket connection in tubular rubber cover and thermal-collecting tube with heat, the interface of this connected mode easily leaks, if the tubing cost of point union employing heavy wall stainless steel tube or copper pipe is high and weight also increases, if adopting thin-wall stainless steel or copper pipe punching to inlay rubber sleeve pegs graft, easily stab wound rubber sleeve, cause leaking.Due to heatproof plastic tube PPR pipe, the one, heatproof is in boiling water temperature or to approach while use at boiling water temperature PPR pipe itself easily aging, and the 2nd, coefficient of dilatation is too large, easily causes the generation of interface drainage.

Summary of the invention:

The duty that the technical problem to be solved in the present invention is to provide a kind of heat collector and attemperater is static pressure, its connected system is non-pressure open, and bathing tap and other water tap in system, have higher use head, and effectively prevent the split type wall-hanging solar water heater of directly-heated that water leakage fault occurs.

The present invention adopts following technical scheme:

The present invention includes support, be located at the outdoor heat collector that thermal-collecting tube on support and incubation chamber form, attemperater is fixed on the indoor position that approaches roof, pipe one end, upper reaches and attemperater bottom delivery port join, the other end is connected with cold point of union in incubation chamber, one end of return duct is connected with attemperater upper interface, the other end divides connecting leg to be connected with the heat in incubation chamber, running water pipe is connected with upper reaches pipe, in the pipeline of upper reaches, be also connected in series a tubing pump, one normally open solenoid valve, one check-valves, adjutage is connected with upper reaches pipe, bathing tap or or other tap be connected to and discharge water in pipeline, the serial connection in pipeline of discharging water is controlled tubing pump, water flow switch.

Cold point of connecting leg and the heat in water injection pipe and incubation chamber in thermal-collecting tube are divided being connected of connecting leg and cross over pipe in thermal-collecting tube in incubation chamber of the present invention, adopt the flange that punches on thin metallic tubd to inlay tubular rubber and overlap grafting.

Good effect of the present invention is as follows: collecting efficiency is high, and cost is low practical, is connected on the bathing tap that discharges water in pipeline and other water tap pressure and increases and meet the demands, and also has the beneficial effects such as easy for installation, fault rate reduction.

Accompanying drawing 1 is structural representation of the present invention

In accompanying drawing 1: 1 support, 2 incubation chamber, 3 cold points of connecting legs, 4 heat point connecting legs, 5 thermal-collecting tubes, 6 water injection pipes, 7 cross over pipes, 8 upper reaches pipes, 9 return pipes, 10 tubing pumps, 11 normally open solenoid valves, 12 attemperaters, 13 evacuated tube, 14 running water pipes, 15 moisturizing switches, 16 water flow switches, 17 mix water valves, 18 rubber sleeves, 20 electric controllers.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in further detail:

As shown in the figure, the present invention includes by support 1, incubation chamber 2, cold point of connecting leg 3, heat and divide connecting leg 4, thermal-collecting tube 5, water injection pipe 6, cross over pipe 7, the outdoor solar thermal collector forming, indoor attemperater 12, the evacuated tube 13 of comprising, cold point of union 3 UNICOMs of 8 one end and outdoor incubation chamber 2 are managed at upper reaches, and the other end is connected with the lower end interface of indoor thermal-insulating water tank 12.Return duct 9, one end are connected with the heat point union 4 of outdoor incubation chamber 2, and the other end is connected with the upper end interface of indoor thermal-insulating water tank 12.Running water pipe 14 is connected with upper reaches pipe 8, in running water pipe 14 pipelines, be provided with moisturizing switch 15, upper reaches is managed and in 8 pipelines, is serially connected with tubing pump 10 and normally open solenoid valve 11, after solar thermal collector absorbs heat, water temperature raises, in the time reaching a fixed difference difference, electric controller 20 is connected tubing pump 10 and is started working, and plays circulation.The lower water of temperature in attemperater 12, manage 8 and cold point of connecting leg 3, water injection pipe 6 enter, thermal-collecting tube 5 bottoms by upper reaches, hot water in thermal-collecting tube 5 enters attemperater 12 through cross over pipe 7, heat point connecting leg 4, return duct 9, approach while equating through circulation warm water tank 12 after a while and the water temperature in thermal-collecting tube 5 on heat collector, now tubing pump 10 quits work, and finishes one action circulation.The duty of tubing pump 10 can be by electric controller 20 and water flow switch control, and heat heat collector being absorbed by circulation is sent to attemperater 12.

When water, when water flow switch 16 also can be connected tubing pump 10 and connect tubing pump 10, normally open solenoid valve 11 is closed, and now obtains higher use head with tap 17.In the time of attemperater 12 lack of water, can open moisturizing switch 15, now check-valves 19 cuts out, and cold water arrives attemperater 12 through cold point of union 3 water injection pipe 6 cross over pipe 7 heat point union 4 return ducts 9.
