Description
Technical field
The present invention relates to the efficient low heat loss solar energy water heater of a kind of interpolation pipe convection of solar energy heat utilization.
Background technology
In the existing solar water heater be made up of all-glass vacuum thermal-collecting tube, spring clip in all-glass vacuum thermal-collecting tube, play the supporting member effect between inner glass tube free end and cover outer glass tube, but, this spring clip is directly connected between the solar selective absorbing coating of inner glass tube free end outer wall and cover outer glass tube inwall, this spring clip just becomes the heat conductor between two pipes, the heat stored by hot water of heating in the sixth of the twelve Earthly Branches in the heat that the solar selective absorbing coating on inner glass tube outer wall is absorbed and inner glass tube, all conduct through spring clip and dissipated to cover outer glass tube, this adds increased the thermal losses of all-glass evacuated solar collector tube, reduce its heat-insulating property, this is a shortcoming existing for existing all-glass evacuated solar collector tube.
In addition, in the existing solar water heater be made up of all-glass vacuum thermal-collecting tube, in vacuum heat collection pipe, the hot water of heating in the sixth of the twelve Earthly Branches is together with the cold water mix to be heated in this pipe, define a kind of heating process of natural convection, that is: the shortcoming of this mode of heating cold water to be heated in the hot water of heating in the sixth of the twelve Earthly Branches in pipe and pipe is not separated, make there is no respective passage between the hot water of heating in the sixth of the twelve Earthly Branches in pipe and cold water to be heated, so, the heating process of this free convection will reduce the solar energy thermal conversion efficiency of all-glass vacuum thermal-collecting tube, thus programming rate and the utilization rate of water in solar water heater is reduced, this is another shortcoming existing for the existing solar water heater be made up of all-glass evacuated solar collector tube.
Object of the present invention: in the efficient low heat loss solar energy water heater of a kind of interpolation pipe convection of the present invention, employ a kind of heat insulation type spring clip all-glass vacuum thermal-collecting tube, heat insulation type spring clip in pipe, both supporting member effect between inner glass tube free end and cover outer glass tube had been played, play again the heat-blocking action between inner glass tube free end and cover outer glass tube, reduced the thermal losses of existing all-glass evacuated solar collector tube, overcome the shortcoming of its poor thermal insulation property; In addition, in the efficient low heat loss solar energy water heater of a kind of interpolation pipe convection of the present invention, a kind of elbow interpolation convection tube is inserted in vacuum heat collection pipe, like this, cold water to be heated in vacuum heat collection pipe is that the elbow of the elbow interpolation convection tube that lower curtate water temperature is lower after attemperater flows into elbow interpolation convection tube, then heating is gone in the bottom flowing to vacuum heat collection pipe.Now, the hot water of heating in the sixth of the twelve Earthly Branches in vacuum heat collection pipe, go upwards flowing in the front upper part of attemperater between vacuum heat-collecting inside pipe wall and elbow interpolation convection tube outer wall, which achieves between cold water to be heated in the hot water and elbow interpolation convection tube heated the sixth of the twelve Earthly Branches in vacuum heat collection pipe, separated by elbow interpolation convection tube, respectively there is the passage of oneself between the two, like this. just define the heating process of mandatory Convection states in vacuum heat collection pipe and between attemperater, thus the solar energy thermal conversion efficiency of vacuum heat collection pipe is substantially increased, also just improve programming rate and the utilization rate of water in solar water heater.
Summary of the invention
The efficient low heat loss solar energy water heater of a kind of interpolation pipe convection of the present invention, it comprises: heat insulation type spring clip all-glass vacuum thermal-collecting tube 1, heat insulation type spring clip 2, thermal insulation barriers 3, elbow interpolation convection tube 4, elbow interpolation convection tube positioning mounting 5, attemperater 6, support 7, cold water to be heated flow to 8, hot water after heating flows to 9.
Feature of the present invention and benefit: in the efficient low heat loss solar energy water heater of a kind of interpolation pipe convection, have employed heat insulation type spring clip all-glass vacuum thermal-collecting tube, the thermal losses of all-glass vacuum thermal-collecting tube can be reduced, improve its heat-insulating property; Have employed elbow interpolation convection tube, can between cold water to be heated in the hot water of heating in the sixth of the twelve Earthly Branches in vacuum heat collection pipe and elbow interpolation convection tube, separated by elbow interpolation convection tube, respectively there is the passage of oneself between the two, like this, just define the heating process of mandatory Convection states in vacuum heat collection pipe and between attemperater, thus substantially increase the solar energy thermal conversion efficiency of vacuum heat collection pipe, also just improve programming rate and the utilization rate of water in solar water heater.The efficient low heat loss solar energy water heater of a kind of interpolation pipe convection of the present invention, thermal losses is low, good heat insulating, solar energy thermal conversion efficiency are high, water programming rate is fast, when winter, cold season used, not easily freezing, improve security and utilization rate that solar water heater uses.
