Description

Solar thermal collector

Technical field:

The utility model relates to the solar thermal collector technical field, refers in particular to a kind of simple in structure, solar thermal collector that production cost is low.

Background technology:

Raising along with economic construction and living standards of the people; the City Garden dwelling house has become trend; the deterioration of energy crisis and environment is also in continuous aggravation simultaneously; for this reason; not only cleaned but also the development and utilization of inexhaustible solar product is needed badly universal; nowadays, solar water heater is exactly most widely used a kind of solar product.

The heat collecting element of solar water heater use at present is mainly full coating film on glass vacuum heat collection pipe, and this thermal-collecting tube mainly contains the defective of the following aspects: 1, inside pipe wall fouling heat exchange mode serious and free convection all makes its heat conduction efficiency be difficult to improve; 2, the pressure-bearing property of all-glass vacuum tube is poor; 3, cost is high and be difficult to penetration and promotion; Generally need be angled when 4, it is laid with ground, so stability is not enough and account for bigger space.

Also use flat casing water-heater at present, promptly it mainly adopts flat solar panel, and this structure is installed more convenient, but its cost is very high, is not suitable for single family and uses.

The utility model content:

The purpose of this utility model is to provide a kind of solar thermal collector at the deficiencies in the prior art, and it is simple in structure, production cost is lower.

For achieving the above object, the utility model adopts following technical scheme: it includes thermal-collecting tube, and its thermal-collecting tube adopts spiral-shaped structure, and thermal-collecting tube has water inlet and delivery port.

Described thermal-collecting tube is fixed on the insulation bottom, and this insulation bottom can adopt materials such as foam, and it can reflex to the sunshine that impinges upon above it on the thermal-collecting tube, increases uptake, but also has the effect of insulation.

Described thermal-collecting tube is the black pipe, to attract solar energy.

Described thermal-collecting tube also can adopt at inwall and scribble the solar absorbing layer structure.

Described thermal-collecting tube top is provided with transparent protection plate, and this baffle is used to protect thermal-collecting tube.

The utlity model has characteristics such as simple in structure, bigger caloric receptivity, and its production cost is lower, is fit to apply.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a user mode schematic diagram of the present utility model;

Fig. 2 is a sectional structure schematic diagram of the present utility model.

The specific embodiment:

See accompanying drawing 1-2, the utility model includes thermal-collecting tube 10, and thermal-collecting tube 10 adopts spiral-shaped structure, and thermal-collecting tube 10 has water inlet 12 and delivery port 14.

Described thermal-collecting tube 10 is fixed on the insulation bottom 20, and this insulation bottom 20 can adopt materials such as foam, and it can reflex to the sunshine that impinges upon above it on the thermal-collecting tube 10, increases uptake, but also has the effect of insulation.

Described thermal-collecting tube 10 is the black plastic pipe, and to attract solar energy, this infrastructure cost is lower.

Described thermal-collecting tube 10 also can adopt glass tube, and coats solar absorbing layer at the glass tube inwall, and this solar absorbing layer is for absorbing the material of solar energy; Perhaps, thermal-collecting tube 10 adopts copper pipe, does corresponding processing to absorb solar energy on copper pipe.

Described thermal-collecting tube 10 tops are provided with transparent protection plate 30, and this baffle 30 is used to protect thermal-collecting tube 10.Baffle 30 of the present utility model adopts clear glass, and baffle 30 is enclosed in thermal-collecting tube 10 on the heat-insulation layer 20, so that heat does not distribute.

See shown in Figure 1ly, be user mode schematic diagram of the present utility model.Be attached with temperature sensor 40 on the thermal-collecting tube 10, temperature sensor 40 is connected with external sensor 50, when the water temperature in temperature sensor 40 is sensed thermal-collecting tube 10 reaches certain numerical value, external sensor 50 expands, and with pitch brace 62 jack-up in the water inlet pipe 60, water flows into thermal-collecting tube 10 heating from water inlet 12, and hot water then flow into outside storage tank from delivery port 14.

The utility model can directly keep flat on the ground, installs very convenient.Thermal-collecting tube 10 also can adopt a plurality of spiral type pipe substring connection to form, to increase heat-absorbent surface.

Thermal-collecting tube 10 of the present utility model adopts helical structure, and water inlet 12 is positioned at the next door, and delivery port 14 is positioned at the middle part, and the advantage of this structure mainly contains: under same floor space, the total length of thermal-collecting tube 10 is bigger, and total caloric receptivity is also just bigger; And current are from water inlet 12 to delivery port 14, and its temperature raises gradually; Simultaneously, it can directly be placed on the ground, does not have angle limits; Cost is very low.

Certainly, the embodiment of the above is a preferred embodiments of the present utility model, and all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
