Abstract
The utility model discloses a solar heat collection tube, which comprises inner tubes and outer tubes, wherein the periphery of the inner tubes is coated with a solar energy absorbing layer, at least two inner tubes are arranged, and the two inner tubes are connected with each other by an inner joint in a sealing way; at least two outer tubes are arranged, and the two outer tubes are connected with each other by an outer joint in a sealing way; sealing rings are arranged between the inner tubes and the outer tubes; the peripheral wall of each outer tube is in a tooth shape; and four stop strips are positioned between the inner tubes and the outer tubes. The solar heat collection tube has large photic area, has the functions of condensation and heating, and can change the lengths of the inner tubes and the outer tubes, thus being taken as the heat collection tube of a solar water heater and a heat insulation liquid transport tube.
Description
Technical field
The utility model relates to a kind of solar water heater assembly, the thermal-arrest pipe fitting that particularly a kind of solar water heater is used.
Background technology
The development and use research of solar energy has been carried out a lot of years, and solar water heater is to utilize solar energy that water is heated, and is the technology of widespread usage in life.Used thermal-collecting tube on the present solar water heater, owing to be that nature irradiation, light-receiving area are little, it is low to exist collecting efficiency, and the inner and outer pipe relative fixed, pipe can not move in making, causes installation inconvenience.
Summary of the invention
The solar energy heat collection pipe that the purpose of this utility model is to provide that a kind of light-receiving area is big, optically focused heating and inner and outer pipe can change length.
In order to achieve the above object, the technical solution of the utility model is: a kind of solar energy heat collection pipe, pipe and outer tube in comprising, interior pipe periphery scribbles solar absorbing layer, and described interior pipe has two at least, and has nipple to be tightly connected between two interior pipes, described outer tube has two at least, and there is coupling to be tightly connected between two outer tubes, and between interior pipe and the outer tube sealing ring arranged, and between interior pipe and the outer tube sealing ring is arranged; The periphery wall of described outer tube is a profile of tooth.
Also be provided with blend stop between pipe and the outer tube in described.
Described blend stop has four.
After adopting said structure, because the outer tube appearance is the tooth limit, heating surface area is big, optically focused, and pipe has two at least in described, and there is nipple to be tightly connected between two interior pipes, described outer tube has two at least, and has coupling to be tightly connected between two outer tubes, and between interior pipe and the outer tube sealing ring is arranged, interior pipe can be moved in outer tube, be convenient to install, can connect into certain length to thermal-collecting tube simultaneously, do insulation and carry liquid effective.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is the structural representation of solar energy heat collection pipe of the present utility model;
Fig. 2 is an outer tube cross-sectional view of the present utility model.
The specific embodiment
As shown in Figure 1, 2, a kind of solar energy heat collection pipe, pipe 1 and outer tube 2 in comprising, interior pipe 1 periphery scribbles solar absorbing layer 7, pipe 1 has two at least in described, and has nipple 3 to be tightly connected between the pipe 1 in two, and described outer tube 2 has two at least, and there is coupling 4 to be tightly connected between two outer tubes 2, and between interior pipe 1 and the outer tube 2 sealing ring 4 arranged; , and between interior pipe 1 and the outer tube 2 sealing ring 4 is arranged; The periphery wall of described outer tube 2 is a profile of tooth.
As shown in Figure 1, also be provided with blend stop 6 between described interior pipe 1 and the outer tube 2, interior pipe 1 and outer tube 2 are separated the formation vacuum chamber, make heat be hedged off from the outer world, heat insulation effect is desirable more.
As shown in Figure 1, for the distance between pipe 1 in better keeping and the outer tube 2, described blend stop 6 has four, is uniformly distributed between interior pipe 1 and the outer tube 2.
The utility model in 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, again whole thermal-collecting tubes are placed sun irradiation down, profile of tooth periphery wall by outer tube 2 focuses on sunlight on the solar absorbing layer 7 of interior pipe 1, by solar absorbing layer 7 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, owing to have sealing ring 4 to be sealed to vacuum cavity between interior pipe 1 and the outer tube 2, make heat be hedged off from the outer world, play the effect of insulation, the characteristics that this shows that this thermal-collecting tube has that the thermal-collecting tube light-receiving area is big, optically focused heating and inner and outer pipe can change length.This thermal-collecting tube both can also can be done the defeated liquid pushing tube of insulation as the thermal-collecting tube of solar water heater.
