Description

Vacuum tube direct-insert pressure-bearing formula solar water heater

Technical field

The utility model is related to solar energy heat utilization field, especially a kind of pressure-bearing type solar water heater.

Background technology

Close type solar water heater is called non-bearing type solar water heater, using universal, structure generally comprise water tank, Holder and the vacuum pumping pipe being directly inserted into inner water tank, this solar water heater thermal efficiency is higher, of low cost, answers With relatively broad, but this solar water heater is typically mounted at the top of building, and the pressure of water outlet depends on water tank and leaching High-low water level between bath is poor, and hot water effluent's pressure is small, and the comfort level of bathing is bad.Pressure-bearing type solar water heater can solve The problem that water pressure is small, and installation site is limited is decided, solar energy heat collection pipe used is generally used copper heat pipe, solar energy heating The connection type of pipe and inner water tank is essentially all thread connecting mode.Due to the higher price of copper heat pipe, copper is used The higher price of the pressure-bearing type solar water heater of the solar energy heat collection pipe of heat pipe lacks the market competitiveness.The valence of glass heat pipe Lattice are cheap, still, can only generally make non-bearing type solar water heater.

Invention content

Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, to provide a kind of structure letter Single, the thermal efficiency is high, and manufacturing cost is low, vacuum tube direct-insert pressure-bearing formula solar water heater easy to use.

In order to solve the above technical problems, the technical solution that the utility model is taken is：Vacuum tube direct-insert pressure-bearing formula solar energy Water heater, including water tank, holder, vacuum tube, watering pipeline and drainage pipeline, automatic liquid supply case, water tank is by liner, shell, guarantor Warm layer and the header being arranged in liner lower part form, and are provided with the hole being inserted into for vacuum tube on the header, vacuum tube is worn It crosses shell to be inserted on header in corresponding hole and seal by silica gel ring, be set in the liner there are one closed heat exchange Courage, heat exchange container are equipped with cycle import and loop exit, recycle import and loop exit passes through wall of inner container and by connector and connection Corresponding sealing joint connection, automatic liquid supply case are connect with header in header, are set in loop exit there are one exhaust pipe, are vented One end of pipe extend into the top of heat exchange container, and the interlude of exhaust pipe is passed through from header and liquid supplementation channel, exhaust pipe it is another One end penetrates into the inner cavity of automatic liquid supply case and reaches liquid level or more.Heat exchange is filled in heat exchange container, header and vacuum tube Medium is supplemented by automatic liquid supply case.Using thermosiphon principle, the higher medium of temperature enters heat exchange container by recycling import In, water in the thin-walled and liner of heat exchange container heat exchange, medium temperature declines, and sinks to the bottom of heat exchange container, and from loop exit Outflow, to form Natural Circulation, the heat of vacuum tube is constantly transmitted in the water in liner.Gas at the top of heat exchange container passes through Exhaust pipe is discharged to the liquid level in automatic liquid supply case or more, which is higher than the top of heat exchange container.

Further to improve, the automatic liquid supply case is float-ball type fluid infusion case, and float-ball type fluid infusion case safely may be used without being powered It leans on.

Further to improve, the liner is enamel inner container, the equal enamel of heat exchange container surfaces externally and internally.

The utility model has the beneficial effects that：Collect hot loop and separated with water loop, to water nonpollution, collects hot loop shape At Natural Circulation, accelerates heat transfer, gas is inevitably will produce during medium circulation, heat exchange can be effectively discharged in exhaust pipe Gas at the top of courage so that it is stifled not will produce gas in cyclic process；Automatic liquid supply case is designed with exhaust outlet, and collection hot loop is logical big Gas, vacuum tube are not subject to pressure, safety-type height；Float-ball type fluid infusion case and liquid supplementation channel are equipped with insulating layer, and good frost resistance can It is arranged in the side of water tank, is not necessarily to electric control, realizes automatic liquid supply；Liner and heat exchange container use enamel technology, compared with stainless steel Cost is lower for matter, and bearing capacity and corrosion resistance are stronger, and longer life expectancy is long.

Specific implementation mode

The utility model is described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, vacuum tube direct-insert pressure-bearing formula solar water heater, including water tank 1, holder 3, vacuum tube 2, upper hose Road and drainage pipeline, automatic liquid supply case 8, water tank is by liner 4, shell, insulating layer and 6 groups of the header in 4 lower part of liner is arranged At being provided with the hole being inserted into for vacuum tube 2 on the header 6, vacuum tube 2 is inserted into corresponding on header 6 across shell It seals, is set in the liner 4 there are one closed heat exchange container 5, heat exchange container 5 is equipped with cycle import in hole and by silica gel ring 501 and loop exit 502, cycle import 501 is deep into the middle part of heat exchange container 5, and loop exit 502 is arranged at the bottom of heat exchange container 5 Portion, recycles import 501 and loop exit 502 passes through the thin-walled and welded seal of liner 4, and then by connector and header 6 Corresponding sealing joint connection, automatic liquid supply case 9 are connect with header 6, are set in loop exit 502 there are one exhaust pipe 7, are vented One end of pipe 7 extend into the top of heat exchange container 5, and the interlude of exhaust pipe 7 is passed through from header 6 and liquid supplementation channel 9, exhaust pipe 7 other end penetrates into the inner cavity of automatic liquid supply case 8 and reaches liquid level or more.In heat exchange container 5, header 6 and vacuum tube 2 Heat transferring medium is filled, is supplemented by automatic liquid supply case 8.Using thermosiphon principle, the higher medium of temperature is by recycling import 501 Into in heat exchange container 5, thin-walled and the water in liner 4 of heat exchange container 5 exchange heat, and medium temperature declines, and sinks to the bottom of heat exchange container 5 Portion, and flowed out from loop exit 502, to form Natural Circulation, the heat of vacuum tube 2 is constantly transmitted in the water in liner 4. More than the liquid level that the gas that medium circulation process generates is discharged to by exhaust pipe 7 in automatic liquid supply case 8, which, which is higher than, changes The top of hot courage 5.

Further, automatic liquid supply case 8 is float-ball type fluid infusion case, and float-ball type fluid infusion case is without being powered, securely and reliably.

Further, liner 4 is enamel inner container, the equal enamel of 5 surfaces externally and internally of heat exchange container.It is inside and outside after the completion of heat exchange container 5 welds Surface carries out enamel processing, is then placed into liner 4 and is welded and fixed, then carries out enamel processing again together with liner 4.
