Abstract

The utility model provides a pressure-bearing all-glass vacuum tube solar heat collector, which comprises an all-glass vacuum heat-collecting tube, a reflection plate, a header, a bracket, and a water inlet and a water outlet arranged on the inner tank of the header. It is characterized in that: a plurality of pressure-bearing heat exchange tubes are added in the header inner tank, and the pressure-bearing heat exchange tubes are all sealed and connected with the parts where the header tubes penetrate. The multiple pressure-bearing heat exchange tubes have a large enough heat exchange area with the hot water in the inner tank, which improves the heat exchange efficiency, and also ensures that the pressure of the pressure-bearing water tank of the pressure-bearing water heater is consistent with the pressure of tap water, with excellent performance and effective use Well, its high pressure performance is also satisfied with the super large area solar heat collection system.

Description

Pressure-bearing type whole glass vacuum tube solar energy can heat collector

The utility model provides a kind of pressure-bearing type whole glass vacuum tube solar energy energy heat collector, belongs to the solar energy utilization technique field.

Existing solar thermal collector mostly is non-bearing type, its heat collector is made up of all-glass vacuum thermal-collecting tube, reflecting plate, union pipe, support and the water inlet, the delivery port that are located on the union pipe inner bag, vacuum heat collection pipe one end is connected with the union pipe inner bag and connects, and the other end is fixed on the support; The heat collector that has improves bearing capacity by the mode of reinforcing tailstock and framework, but the bearing capacity raising is limited, and effect is undesirable.The solar water heater of the high pressure-bearing of family expenses needs the heat collector of high pressure-bearing at present, the solar thermal collection system of especially big area need be realized cycle heat exchange by high-lift water circulating pump, require each unit heat collector also must can bear enough pressure, but existing solar thermal collector also far can not satisfy above-mentioned requirements.

The purpose of this utility model provides a kind of thermal efficiency height, result of use pressure-bearing type whole glass vacuum tube solar energy good, high pressure-bearing can heat collector.

The purpose of this utility model is achieved in that

The water inlet, the delivery port that comprise all-glass vacuum thermal-collecting tube, reflecting plate, union pipe, support and be located on the union pipe inner bag are formed, it is characterized in that: set up many pressure-bearing heat exchanger tubes in the union pipe inner bag, the position that pressure-bearing heat exchanger tube and union pipe run through all is tightly connected.

Described pressure-bearing type whole glass vacuum tube solar energy energy heat collector, many pressure-bearing heat exchanger tubes can adopt parallel way, form total water inlet port, water outlet port.

Described pressure-bearing type whole glass vacuum tube solar energy energy heat collector, many pressure-bearing heat exchanger tubes can adopt the compound modes of series connection more in parallel earlier, form intake port and water outlet port.

Described pressure-bearing type whole glass vacuum tube solar energy energy heat collector, the pressure-bearing heat exchanger tube in the union pipe inner bag can be straight tube, coiled pipe or bellows.

Its operation principle is: the hot water in the union pipe inner bag constantly with the pressure-bearing heat exchanger tube in hydrothermal exchange, it is heated, the hot water in the pressure-bearing heat exchanger tube can be directly and the water in the press-bearing water tank carry out heat exchange by free convection.Perhaps, the hot water in the pressure-bearing heat exchanger tube in the single or multiple connection in series-parallel heat collectors carries out heat exchange by the water in water circulating pump and the water tank.

The utility model compared with prior art has following advantage:

1, many pressure-bearing heat exchanger tubes that are straight tube, coiled pipe or bellows are through the union pipe inner bag, carry out heat exchange with hot water in the union pipe inner bag, enough big heat exchange area are arranged, thermal efficiency height;

2, the union pipe inner bag directly is not connected with water tank, link to each other with water tank by many pressure-bearing heat exchanger tubes before the union pipe inner bag, make union pipe inner bag pressure-bearing not substantially like this, long service life, and the water tank that is connected with heat collector can make press-bearing water tank and bear tap water pressure, is not subjected to the influence of its installation site, function admirable, discharge pressure is big, and result of use is good;

3, the union pipe of even number root pressure-bearing heat exchanger tube is set, and its intake-outlet can be located at the same upside or the same downside of union pipe easily, is convenient to the water-in and water-out house steward is located at together, helps unified insulation.
