Abstract

The utility model relates to a compound internal-circulating solar energy water heater, which comprises an internal-circulating hot water tank and a combined casing. As the heat collector of the compound internal-circulating solar energy water heater adopts composite metal plastic thin walled material, the compound internal-circulating solar energy water heater is pressure-proof, long in service life and inexpensive. As the mechanization molding is adopted, the compound internal-circulating solar energy water heater is especially suitable for the mass production. The compound internal-circulating solar energy water heater belonging to a popular product is suitable for large area covering applications.

Description

Compound internal-circulating solar energy water heater

The utility model relates to the solar energy utilization, is a kind of compound internal circulation solar energy water heater.

Existing red mud plastic pocket type water heater, having a kind of is the hot-water bottle that tans by the sun that is not incubated measure, and its thermal efficiency is low, and the life-span is short, is in greenware condition substantially; Be the vexed solarization pocket type water heater that lagging casing is housed again, because its flat water bag itself is unsetting, the water bag calorific intensity is lower, make it can not directly bear hydraulic pressure from the beginning, can only be placed in the plane, water heater is to adding the water water level, exhaustion spill, must there be corresponding requirement and measure in aspects such as backwater, otherwise problem is more, weak effect.

Existing various metal structure products, no matter closing-sunning type or circulating, it is more to produce required artisan craftsmanship, labour intensity is big, is not suitable for industrialized mass production, wherein circulating support, supporting water tank must be set, built on stilts install etc., application management is trouble; In the recent period the copper aluminum pipe product that occurs consumes valuable non-ferrous metal, and price is high, and customer investment is difficult to reclaim, and domesticly should not promote at present; The product that galvanized sheet is made, the material cost height, corrosion is very fast, general about 3 years of service life; Other has many product designs supporting reasonable inadequately, causes system often to have to shine the water yield few, phenomenon such as leak out of control, and user's repercussion is bigger.

Existing plastic construction water heater: wherein a kind of overall plastic product, its water capacity is few, there is intrinsic siphon retention problems in the hot water emission, the rubber plug connector many and easily be full of cracks leak, inconvenient facade is installed.

This utility model is at the needs that all adapt to mechanization production in enormous quantities and actual life aspect structure and the cost, it will change the conventional production methods of water heater, simplify production technology, reduce heavy work, alleviate non-ferrous metal in short supply, polyethylene, galvanized sheet supply the market, it is topped that its product is hopeful to be used to the large tracts of land collection, makes the solar energy utilization really have meaning.

The utility model is achieved in that

1, insulation die cavity (2), be set in the assembling frame (10) of the supporting hot hydrophone load of die cavity outside, framework upper is equipped with glass positioning element (11) and hangs parts (9), and adjustable support leg (7, hang position 5) is equipped with in the bottom, and framework and supporting leg bottom bolt are with lacing wire (8, hang 6)

2, hot water narrow-necked earthen jar (3): promptly handle circulating hot water narrow-necked earthen jar in the garden cylindricality of making by tinplate or aluminium foil through the plastic-coated baking, two ends are used and are had evagination expansion loop and hole, flange garden to be connected into the end cap end socket of Inlet and outlet water through hole (4).

3, the hot water narrow-necked earthen jar is made on special-purpose assorted equipment, and it is the mechanical production line of the long jug forming of a cover.

4, method of attachment: one section sebific duct is filled in through hole, insert in the elastic rubber tube with threeway glass short tube again, pegged graft with sebific duct respectively in the three-way pipe two ends then.

This water heater constitutes whole stressed composite thermal insulation shell with metal material seldom, carries simple rack, and cost and mounting cost are low, and orientation angles is easy to adjust, outward appearance and safe good heat insulating.The vexed solarization device of interior circulation adopts new shaped steel to mould or aluminium plastic composite material, to replace market material consumption in short supply, have excellent weatherability against corrosion, heat transfer effect is good, and application machine changes into type, the working (machining) efficiency height, labour intensity is low, places side by side by certain height difference between the hot water narrow-necked earthen jar, makes circulation in system's inner fluid generation naturally, improve the hot water uniformity, improved the thermal efficiency.

Description of drawings: cross-section schematic diagram

1, cover glass; 2, insulation die cavity;

3, hot water narrow-necked earthen jar; 4, Inlet and outlet water through hole;

5,7, supporting leg; 6,8, lacing wire

9, hang parts; 10, assembling frame;

11, glass positioning element.

Embodiment:

1, assembling frame, (δ=1～1.2m/m) is in advance by size blanking, indent, boring, bending, riveting molding, through antirust processings after and be incubated the die cavity suit with the iron plate bar; Insulation die cavity expandable styrene mould molding during production in enormous quantities, the outside is coated with the protection decorative emulsion paint.

2, interior circulating hot water narrow-necked earthen jar, on special equipment, make φ 132 * 850mm narrow-necked earthen jar shape body with 18 tinplates of plastic-coated, soak with protective coating, the Inlet and outlet water three-way connection of packing at two ends, tetrad is linked to be integral body by upper and lower two rows, puts into the insulation die cavity, installs glass and positioning element is finished product, every vexed solarization device water capacity is about 11kg, every water heater daylighting area 0.5m ², water capacity 45kg, or daylighting area 1.5m ², water capacity 130kg.

3, the special equipment of vexed solarization device moulding is the supporting long tube Cheng Yuanji of specialized designs, long limit button seam machine and long can seamer; All the other equipment have: blanker, cornering machine, make the machine of lid, coating machine, dryer.

Claims

1, a kind of compound internal circulation solar energy water heater, this water heater is made up of the hot water narrow-necked earthen jar (3) by the certain height difference horizontal, there is an Inlet and outlet water through hole (4) at each hot water narrow-necked earthen jar two ends at a low level or a high position respectively, feature of the present utility model is that the hot water narrow-necked earthen jar is made by tinplate or aluminium foil, inside and outside wall coated coating protecting layer, the hot water narrow-necked earthen jar is plugged on together by three-way pipe and sebific duct by the Inlet and outlet water through hole at two ends.
