Description
Technical field: the invention belongs to a kind of solar energy heating parts of field of thermal engineering, particularly a kind of vacuum solar heat-collecting pipe.
Technical background: solar energy is a kind of inexhaustible natural energy source, and in order to utilize heat energy wherein, various solar energy heating parts arise at the historic moment.Because the thermal conversion efficiency height of heat pipe has been widely used in the solar thermal collector, the invention of vacuum heat-pipe makes the thermal conversion efficiency of solar thermal collector reach a new level.The vacuum heat-pipe that generally uses is made up of inside and outside layer glass pipe now, it between two pipes vacuum cavity, inner tube outer surface scribbles heat absorbing coating, interior dress working medium, outer tube one end closure, the other end insert water tank and carry out heat exchange, the shortcoming of this vacuum heat-pipe is: one, function singleness, the heat-collecting part of solar water heater can only be used as, other helioplant can not be used for, as: solar energy stove, solar heating device etc.Two, thermal conversion efficiency is still not high enough.Three, install, use, transportation shortcoming easily inadequately all.
Summary of the invention: the shortcoming that the objective of the invention is to overcome prior art, provide a kind of thermal conversion efficiency higher, not only can do the heat-collecting part of solar water heater, can also do the heat-collecting part of other helioplant, install, use, transport all vacuum solar heat-collecting pipe easily.
The objective of the invention is to realize by following technical scheme; Vacuum solar heat-collecting pipe provided by the present invention, form by the metal heat pipe of heat absorbing coating and the glass tube of outside by inner surface, in, there is support card to hold mutually between the outer tube, the sealing of outer glass pipe one end, the other end is equipped with a sealing-plug, be vacuum cavity between interior metal heat pipe and the outer glass pipe, the evaporator section of metal heat pipe is loaded in the glass tube, from the equipped sealing-plug of glass tube one end, stretch out, the isothermal heat conduction section and the liquid back pipe that are characterized in the metal heat pipe are flexible metallic hose, the isothermal heat conduction section of metal heat pipe, the evaporator section of liquid back pipe and metal heat pipe, be sealed attachment between the condensation segment, the condensation segment of metal heat pipe is higher than the horizontal level of its evaporator section.Describe operation principle of the present invention below in detail: vacuum solar heat-collecting pipe is the main heat collecting part of solar thermal collector, formed vacuum solar heat-collecting pipe by inner surface by the metal heat pipe of heat absorbing coating and the glass tube of outside among the present invention, by interior, support card between the outer tube is placed in glass tube inside with the metal heat pipe, in, outer tube does not contact, the vacuum cavity that forms between the two becomes good thermal insulation layer, prevent that the heat that the metal heat pipe is absorbed from outwards distributing, be loaded on the heat of the metal heat pipe evaporator section absorption solar energy in the glass tube, make the working medium evaporation in the metal heat pipe, isothermal heat conduction section outside stretching out glass tube reaches condensation segment, after heat exchange, become liquid refrigerant at condensation segment, flow back to evaporator section through liquid back pipe, again be heated, evaporation forms thermal cycle, metal heat pipe isothermal heat conduction section and liquid back pipe also can share a flexible metallic hose in this vacuum solar heat-collecting pipe, and its operation principle is the same.Because the isothermal heat conduction section of metal heat pipe and liquid back pipe are the outside flexible metallic hose that is surrounded by the flexible heat-insulating layer, the direction of installing, using has randomness, the collapsible transportation of flexible metallic hose, so install, use, transportation is all very convenient, its outside is surrounded by flexible heat-insulation layer and makes the unlikely loss of heat in the process of heat transmission.Because the condensation segment of metal heat pipe is higher than the horizontal level of its evaporator section, but this vacuum solar heat-collecting pipe level is used, and when using like this, working medium all is positioned evenly over the bottom of metal heat pipe evaporator section, more increase the heating surface area of working medium, improved thermal conversion rate.This vacuum solar heat-collecting pipe is as to be used in combination efficient higher with translation surface optically focused reflecting surface, can lie in a horizontal plane in because of this vacuum solar heat-collecting pipe on the focal line of curved surface translation optically focused reflecting surface, the evaporator section of metal heat pipe all is on the focal line of optically focused reflecting surface, after the sunlight line focus reflection heat is concentrated on the metal heat pipe of optically focused reflecting surface focal line, again because working medium all is positioned evenly over the bottom of metal heat pipe evaporator section, make working medium be subjected to thermal evaporation soon, he has improved thermal conversion efficiency widely.Owing to connect by flexible isothermal thermal conductive metal pipe between the evaporator section of this vacuum solar heat-collecting pipe and the condensation segment, this vacuum solar heat-collecting pipe not only can be done the heat-collecting part of solar water heater, can also do the heat-collecting part of solar energy stove and solar heating device, use it, can easily the solar heat outside the room be transported in the room, be well suited for skyscraper and use.
Vacuum solar heat-collecting pipe provided by the present invention compared with prior art has the thermal conversion efficiency height, installation, use, transportation all make things convenient for, and, it not only can do the heat-collecting part of solar water heater, can also do the heat-collecting part of solar energy stove and solar heating device, be well suited for skyscraper and use.
