Description
Technical field
The utility model relates to a kind of flat-plate collector, especially a kind of flat-plate collector that is used for solar water heater.
Background technology
In recent years, solar water heater technical development speed is very fast, and solar water heater becomes one of daily electric equipment gradually, is numerous families and unit acceptance and use.At present, the domestic solar water heater generally comprises assemblies such as water storage box, heat collector, pipeline, valve and support.Heat collector includes electron tubes type heat collector and flat-plate collector.The electron tubes type heat collector has advantages such as antifreeze good frost resistance, heat loss coefficient be little.Flat-plate collector has thermal efficiency height, helps the use of the circulatory system, load performance is high and steady performance when forming big system.The electron tubes type heat collector generally is usually used in family expenses.In large-scale place,, when using solar water heater, often adopt a large amount of heat collectors to form larger collecting system like hotel, natatorium and factory etc.; Adopt the electron tubes type heat collector this moment, need be between the thermal-collecting tube with material seals such as plastics or rubber, and the long-time back of using is prone to leak.When adopting flat-plate collector, connect through metal between heat collector and the hot-water heating system, connection reliability is higher, and the stability of system is also higher.
Flat-plate solar heat collector mainly is made up of several parts such as absorber plate, transparent cover plate, thermal insulation layer and housings.Absorber plate is the parts that absorb solar radiant energy in the flat-plate solar heat collector and transmit heat to heat-transfer working medium.On the absorber plate of writing board shape, all be furnished with comb and collector usually.Comb is meant that absorber plate is vertically arranged and the parts of formation fluid passage; Collector is meant the absorber plate horizontal parts that connect some combs and constitute the fluid passage in two ends up and down.In the prior art, comb and collector generally are the pipes of inner wall smooth, and the pipe of this inner wall smooth has the lower shortcoming of heat exchange efficiency, are unfavorable for improving the thermal efficiency of water heater.
The utility model content
The utility model is the weak point that exists in the above-mentioned prior art for avoiding, and a kind of flat-plate collector that is used for solar water heater is provided, to improve heat exchange efficiency.
The utility model adopts following technical scheme for the technical solution problem.
The flat-plate collector that is used for solar water heater; Comprise absorber plate, transparent cover plate, base plate, thermal insulation layer and housing; Its design feature is, said transparent cover plate, base plate and housing constitute shell, and said absorber plate is located in the shell; Said thermal insulation layer is located between absorber plate and the base plate, is provided with comb and collector in the absorber plate; The inwall of said comb and collector is provided with internal thread.
The design feature of the flat-plate collector that is used for solar water heater of the utility model also is:
Said transparent cover plate is a plate glass.
Said transparent cover plate is a glass epoxy.
Compared with present technology, the utility model beneficial effect is embodied in:
In the utility model,, enlarged the surface area of inside pipe wall, more helped carrying out between pipe and the fluid media (medium) heat exchange, improved the efficient of heat exchange, and then can improve the efficiency of utilization of solar water heater owing on tube wall, be provided with screw thread.The utility model needs only the purpose that can realize improving heat exchanger effectiveness at the tube wall machining internal thread, need not existing apparatus is structurally improved, and realization and improvement cost are low easily.The employing glass epoxy can improve the shock resistance of heat collector, not fragile heat collector.The flat-plate collector that is used for solar water heater of the utility model has and can improve heat exchanger effectiveness, realizes and advantage such as improvement cost is low easily.

Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is comb and the axial sectional drawing of collector of the flat-plate collector of the utility model.
Label in accompanying drawing 1, accompanying drawing 2 and the accompanying drawing 3: 1 absorber plate, 2 transparent cover plates, 3 base plates, 4 thermal insulation layers, 5 housings, 6 combs, 61 internal threads.
Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, be used for the flat-plate collector of solar water heater, comprise absorber plate 1, transparent cover plate 2, base plate 3, thermal insulation layer 4 and housing 5.Said transparent cover plate 2, base plate 3 and housing 5 constitute shells, and said absorber plate 1 is located in the shell, and said thermal insulation layer 4 is located between absorber plate 1 and the base plate 3, is provided with comb 6 and collector in the absorber plate 1; The inwall of said comb 6 and collector is provided with internal thread 61.On the inwall of comb and collector, be provided with screw thread, enlarged the surface area of inside pipe wall, more help carrying out between pipe and the fluid media (medium) heat exchange, improve the efficient of heat exchange, and then can improve the efficiency of utilization of solar water heater.The utility model needs only the purpose that can realize improving heat exchanger effectiveness at the tube wall machining internal thread, need not existing apparatus is structurally improved, and realization and improvement cost are low easily.
Said transparent cover plate 2 is a plate glass.Plate glass has characteristics such as infra-red transmittance is low, thermal conductivity factor is little, weather resistance is good, can satisfy the requirement of solar thermal collector transparent cover plate well.
Said transparent cover plate 2 is a glass epoxy.Glass epoxy has solar transmission than high, characteristics such as thermal conductivity factor is little, impact strength height, can protect absorber plate not to be damaged better.
The flat-plate collector of the utility model can be applicable to numerous areas such as domestic water heating, swimming pool heating, water for industrial use heating, constructure heating and air-conditioning.Comb 6 is generally copper pipe with the collector (not shown).
