Abstract

The utility model provides a whole glass vacuum tube solar energy heat collector, which comprises a plurality of whole glass vacuum tube solar energy heat collecting tubes, a bracket, a reflecting plate, a connecting collecting tube, an air outlet and two interfaces, wherein, one interface is arranged at the upper part of the side surface of the inner liner of the connecting collecting tube; the other interface is arranged at the middle part or the lower part of the inner liner of the connecting collecting tube; an included angle alpha is formed between the two interfaces and the side surface; the included angle alpha is within 90 DEG to 160 DEG. The utility model can assure that an included angle which is larger than 0 DEG is formed between pipelines in the position of the interfaces and the horizontal direction to be favorable to the convection for hot water in the inner liner of the connecting collecting tube to a heat storage water tank, and the efficiencies of the convection and the heat transfer are high.

Description

All-glass solar vacuum tubular collector

The utility model provides a kind of all-glass solar vacuum tubular collector, belongs to the solar energy utilization technique field.

At present, full glass vacuum tube solar water heater steps into common people family with advantage energy-conservation, that cost is low, the thermal efficiency is high already, with regard to its technology, generally comprise complete glass vacuum sun thermal-collecting tube, connecting pipe, reflector, support and the water inlet that is communicated with the connecting pipe inner bag, delivery port, since the water inlet that is communicated with the connecting pipe inner bag, delivery port various install and use more than the place and the angle of horizontal direction less than 0 °, promptly downward-sloping, be unfavorable for that hot water in the connecting pipe inner bag is to the heat storage water tank convection current, convection heat transfer' heat-transfer by convection efficient is low, has influenced its result of use.

The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, convection heat transfer' heat-transfer by convection efficient height, all-glass solar vacuum tubular collector that result of use is good.

The purpose of this utility model is achieved in that

Comprise some whole glass vacuum tube solar energies energy thermal-collecting tubes, support, reflector, connecting pipe, gas outlets and two interfaces that are communicated with connecting pipe, connecting pipe is made up of connecting pipe inner bag, connecting pipe shell and heat-insulation layer, it is characterized in that: an interface is arranged on the top of connecting pipe inner bag side, another interface is arranged on the middle part or the bottom of connecting pipe inner bag side, two interfaces all become certain included angle α with this side, and angle α is between 90 ° and 160 °.

The utility model compared with prior art, in any case install, total energy guarantees that the interface pipeline becomes the angle greater than 0 ° with level, helps hot water in the connecting pipe inner bag to the heat storage water tank convection current, convection heat transfer' heat-transfer by convection efficient height, result of use is good.

Fig. 1 is a part-structure schematic diagram of the present utility model;

The utility model is described in further detail below in conjunction with accompanying drawing:

Connecting pipe is made up of connecting pipe inner bag 6, connecting pipe shell 4 and heat-insulation layer 5, and be communicated with some complete glass vacuum sun thermal-collecting tubes 2, its top is provided with gas outlet 1, heat-insulation layer 5 is arranged between connecting pipe inner bag 6 and the connecting pipe shell 4, on the top of connecting pipe inner bag 6 sides an interface 3 is set, middle part or bottom in connecting pipe inner bag 6 sides are provided with another interface 7, two interface correspondences are connected with heat storage water tank through pipeline, and become certain included angle α with this side, angle α is between 90 ° and 160 °.The pipeline and the horizontal direction that have so just guaranteed to be connected between two interfaces and the heat storage water tank have the inclination angle that necessarily makes progress, help in the connecting pipe inner bag 6 hot water preferably with heat storage water tank in the water convection current.
