Abstract
The invention discloses a novel separation membrane layer type vacuum tube of a solar water heater. The novel separation membrane layer type vacuum tube of the solar water heater comprises an outer glass tube and an inner glass tube. The outer glass tube and the inner glass tube are concentric circular tubes. The tube opening portion of the outer glass tube is connected with the tube opening portion of the inner glass tube through a molten glass tube. The tail portion of the inner glass tube is fixed on the outer glass tube. A vacuum interlayer is formed between the outer glass tube and the inner glass tube. An infrared reflecting layer, an absorption layer and an antireflection layer are arranged on the outer wall of the inner glass tube in sequence from inside to outside. The infrared reflecting layer is evenly attached to the outer wall of the inner glass tube in a 360-degree mode. The absorption layer is evenly attached to the infrared reflecting layer in a 0-180-degree mode. The anti-reflecting layer is evenly attached to the absorption layer. By the adoption of the novel separation membrane layer type vacuum tube of the solar water heater, when the solar water heater is not used, operation of the vacuum tube can stop according to needs, and therefore the service life of the solar water heater is prolonged.
Description
Technical field
The invention belongs to domestic solar water heater's technical field, be specifically related to a kind of solar water heater vacuum-tube that simultaneously there is heat absorption function and reflection function.
Background technology
Solar water heater refers to the equipment that utilizes the energy that contains in sunlight that water is heated, and belong to a kind of of renewable energy technologies, and solar water heater vacuum-tube is the core parts of solar water heater, is described as " heart " of solar water heater.Existing solar energy vacuum tube is to adopt two glass tubes of double-layer coaxial to make, and outer layer glass tube plays the protection to inner layer glass; Be coated with the heat-sink shell that absorbs the solar radiation energy at the inner layer glass tube outer surface, heat-sink shell is on 360 ° of outer walls that evenly are attached to inner layer glass tube.In this case, once the client installs the water heater with this kind of vacuum tube, can at every moment receive the irradiation of sunlight in sun-drenched situation, but because owner has a holiday or systemic breakdown needs repairing, while not needing to use this water heater, the hot water that this vacuum tube produces is exactly that a kind of waste even damages because high temperature causes heat collecting element, causes water heater to move, the service life of shortening heat hydrophone.
Summary of the invention
The technical problem to be solved in the present invention is the defect that overcomes prior art, and a kind of Novel separation film laminar solar water heater vacuum-tube is provided, and when not using water heater, this vacuum tube can quit work as required, thereby extends the service life of water heater.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of Novel separation film laminar of the present invention solar water heater vacuum-tube, comprise outer glass pipe and inner glass tube, described outer glass pipe is concentric pipe with described inner glass tube, the spout part of described outer glass pipe is connected by the molten glass pipe with the spout part of described interior glass, the afterbody of described inner glass tube is fixed on described outer glass pipe, between described outer glass pipe and described inner glass tube, it is vacuum interlayer, be disposed with from inside to outside infrared reflecting layer on described inner glass tube outer wall, absorbed layer and anti-reflection layer, described infrared reflecting layer 360 degree evenly are attached on described inner glass tube outer wall, described absorbed layer 0～180 degree evenly is attached on described infrared reflecting layer, described anti-reflection layer evenly is attached on described absorbed layer.
Preferably, described inner glass tube afterbody is fixed on described outer glass pipe by getter support, on described getter support, getter is installed.Getter is used for absorbing the gas residued in vacuum tube, also can be used for absorbing the gas that enters vacuum tube, keeps higher vacuum, and then extends the service life of vacuum tube simultaneously.
Preferably, described absorbed layer 180 degree evenly are attached on described infrared reflecting layer.
Preferably, the high borosilicate that the material of described outer glass pipe and inner glass tube is the coefficient of expansion 3.3.
Preferably, described absorbed layer is cupric oxide, black nickel, black chromium, black zinc or black copper.
On the outer wall of inner tube of solar energy vacuum tube of the present invention, be coating for selective absorption (infrared reflecting layer, absorbed layer, anti-reflection layer), infrared reflecting layer is 360 degree and evenly is attached on the inner glass tube outer wall, absorbed layer is 0～180 degree and evenly is attached on infrared reflecting layer, and anti-reflection layer evenly is attached on absorbed layer.During normal the use, absorbed layer is received to sunlight upward, when not in use vacuum tube Rotate 180 °, infrared reflecting layer upward, flash back the sunlight, vacuum tube does not produce heat, and system is in resting state.
The number of degrees that absorbed layer and anti-reflection layer adhere on infrared reflecting layer, must be arranged between 0～180, if be greater than 180 degree,, when not using water heater, in any case rotation always has solar radiation on absorbed layer, can make equally vacuum tube produce heat.
The beneficial effect that the present invention reaches is:
The present invention arranges coating for selective absorption on inner glass tube, makes water heater when not using, and vacuum tube can quit work as required, thereby extends the service life of water heater.
