Abstract
The utility model relates to a solar heat collecting tube belonging to an accessory of a solar water heater. The solar heat collecting tube comprises an inner tube and an outer tube, wherein the outer surface of the inner tube is coated with a heat absorbing layer, the inner tube and the outer tube are supported and isolated by a support post, a sealing ring is arranged between the inner tube and the outer tube, and the outer surface of the outer tube is provided with ledges. As the ledges are arranged on the outer surface of the outer tube of the solar heat collecting tube to form a convex-concave surface, the light-receiving area is greatly increased; due to the adoption of light-gathered heating, the solar heat collecting tube has high heat collecting efficiency; the heat absorbing layer is arranged on the inner tube so that the sunlight are focused on the heat absorbing layer outside the inner tube; a gap between the inner tube and the outer tube is sealed by the sealing ring to form a vacuum cavity so that the solar heat collecting tube takes the effects of heating and heat insulation on water in the inner tube; the inner tube can move in the outer tube so that the solar heat collecting tube is convenient to install; and meanwhile, a plurality of heat collecting tubes can be connected to a certain length so as to be used as a heat-insulation liquid conveying pipeline.
Description
Technical field
The utility model relates to a kind of solar energy heat collection pipe, belongs to the solar water heater accessory.
Background technology
Solar water heater utilizes solar energy that water is heated, and is widely used in life, and just by the nature irradiation, light-receiving area is little for used thermal-collecting tube, and it is low to exist collecting efficiency, and the inner and outer pipe relative fixed, and interior pipe can not move, and inconvenience is installed.
The utility model content
The purpose of this utility model is to provide a kind of solar energy heat collection pipe, and light-receiving area is big, can heat by optically focused, and the collecting efficiency height, and interior pipe is removable, and easy for installation.
Solar energy heat collection pipe described in the utility model, pipe and outer tube in comprising, its inner tube outer surface scribbles heat-sink shell, supports isolation and establishes sealing ring by support column between interior pipe and the outer tube, and the outer surface of outer tube is provided with fin.
Wherein:
Interior pipe can be respectively equipped with nipple and the coupling that is used to be connected with outer tube, the convenient connection, suitable adjustment length.Support isolation by support column between interior pipe and the outer tube, it is individual comparatively suitable that support column is provided with 5-10.
The utility model compared with prior art has the following advantages:
Because the outer surface of solar energy heat collection pipe outer tube is provided with fin, form male and female face, increased light-receiving area greatly, the optically focused heating, the collecting efficiency height has heat-sink shell on inner pipe, makes sunlight manage on the outer heat-sink shell in focusing on, become the cavity of vacuum between the inner and outer pipe by seal ring seal, internally water plays the effect of heat tracing in the pipe, and interior pipe can move in outer tube, is convenient to installation, simultaneously can connect into certain length to thermal-collecting tube, can be used as insulation and carry the liquid pipeline.
Description of drawings
Fig. 1, the utility model one example structure schematic diagram;
A-A cross-sectional view among Fig. 2, Fig. 1.
Among the figure: 1, interior pipe 2, outer tube 3, fin 4, heat-sink shell 5, support column 6, nipple 7, coupling 8, sealing ring.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
As shown in the figure, solar energy heat collection pipe described in the utility model, pipe 1 and outer tube 2 in comprising, pipe 2 outer surfaces scribble heat-sink shell 4 in it, support the heat-insulation and heat-preservation effect of having isolated by support column 5 between interior pipe 1 and the outer tube 2, and establish sealing ring 8 and form vacuum cavity, the outer surface of outer tube 2 is provided with fin 3, can constitute the convex lens principle, sunlight is focused on the heat-sink shell 4 of interior pipe 1, in pipe 1 can be respectively equipped with nipple 6 and the coupling 7 that is used to be connected with outer tube 2, the convenient connection, the suitable thermal-collecting tube length of adjusting.Support isolation by support column 5 between interior pipe 1 and the outer tube 2, it is individual comparatively suitable that support column 5 is provided with 5-10.
During use, thermal-collecting tube one end of certain-length is linked to each other with water inlet pipe, the other end links to each other with outlet pipe, under with whole thermal-collecting tubes placement sun, shine, by the fin 3 on outer tube 2 outer walls sunlight is focused on the interior pipe 1 outer heat-sink shell 4, by heat-sink shell 4 water is being heated, can obtain the hot water of higher temperature at last at outlet pipe.Can also connect into thermal-collecting tube simultaneously the liquid-transport pipe-line of certain-length by inside and outside joint 6,7, owing to have seal ring seal to become vacuum cavity between the inner and outer pipe 1,2, make heat be hedged off from the outer world, play the effect of insulation, this shows that this thermal-collecting tube can be as the thermal-collecting tube of solar water heater, also can do the insulation carrier pipe, and easy for installation, and the thermal-collecting tube light-receiving area is big so this thermal-collecting tube has, the optically focused heating is managed movably characteristics in reaching.
