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 is and in particular to one kind has heat absorption function and reflection simultaneously
The solar water heater vacuum-tube of function.
Background technology
Solar water heater refers to equipment water heated using the energy containing in sunlight, belongs to renewable energy technologies
One kind, and solar water heater vacuum-tube is the core parts of solar water heater, is described as " the heart of solar water heater
Dirty ".Existing solar energy vacuum tube is made of two glass tubings using double-layer coaxial, and outer layer glass tube plays to inner layer glass
Protection；It is coated with the heat-sink shell absorbing solar radiation energy in inner layer glass tube outer surface, heat-sink shell is uniformly attached in 360 °
On the outer wall of inner layer glass tube.In this case, client is once install the water heater with this kind of vacuum tube, in sunlight
The irradiation of sunlight can at every moment be received in the case of abundance, but because owner has a holiday or systemic breakdown needs repairing, no
When needing using this water heater, the hot water that this vacuum tube produces is exactly a kind of waste even because high temperature leads to heat collecting element to damage
Bad, cause water heater cannot run, shorten the service life of water heater.
Content of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, provides a kind of seperation film laminar solar heat
Water heater vacuum-tube, when not using water heater, this vacuum tube can quit work as needed, thus extending the use of water heater
Life-span.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of present invention seperation film laminar solar water heater vacuum-tube, including outer glass pipe and inner glass tube, described outer
Glass tubing and described inner glass tube are concentric pipe, and the spout part of described outer glass pipe passes through to melt with the spout part of described interior glass
Change glass tubing to connect, the afterbody of described inner glass tube is fixed on described outer glass pipe, described outer glass pipe and described interior glass
It is vacuum interlayer between pipe, described inner glass tube outer wall is disposed with infrared reflecting layer, absorbed layer and anti-reflection from inside to outside
Layer, 360 degree of described infrared reflecting layer is evenly affixed on described inner glass tube outer wall, and described absorbed layer 0～180 degree is uniformly adhered to
On described infrared reflecting layer, described anti-reflection layer is evenly affixed on described absorbed layer.
Preferably, described inner glass tube afterbody is fixed on described outer glass pipe by getter support, described getter
Getter is provided with support.Getter is used for absorbing the gas residuing in vacuum tube, may also be used for being absorbed into simultaneously
The gas of vacuum tube, keeps higher vacuum, and then extends the service life of vacuum tube.
Preferably, described absorbed layer 180 degree is evenly affixed on described infrared reflecting layer.
Preferably, the material of described outer glass pipe and inner glass tube is the high borosilicate of the coefficient of expansion 3.3.
Preferably, described absorbed layer is copper oxide, black nickel, black chromium, black zinc or black copper.
It is coating for selective absorption (infrared reflecting layer, absorbed layer, anti-reflection on the outer wall of inner tube of solar energy vacuum tube of the present invention
Layer), infrared reflecting layer is evenly affixed on inner glass tube outer wall in 360 degree, and absorbed layer is evenly affixed to infrared in 0～180 degree
On reflecting layer, anti-reflection layer is evenly affixed on absorbed layer.Normal absorbed layer is received upward when using sunlight, when not in use
Vacuum tube rotates 180 °, infrared reflecting layer upward, reflects sunlight, vacuum tube does not produce heat, and system is in a dormant state.
The number of degrees that absorbed layer and anti-reflection layer adhere on infrared reflecting layer it is necessary to be arranged between 0～180, if greater than
180 degree, then, when not using water heater, rotate anyway, always has sunlight and is radiated on absorbed layer, equally can make vacuum tube
Produce heat.
The beneficial effect that the present invention is reached is:
The present invention arranges coating for selective absorption on inner glass tube, makes water heater when not in use, and vacuum tube can root
According to needing to quit work, thus extending the service life of water heater.
