Embodiment approach

[0017] see figure 1 As shown, it is a schematic cross-sectional view of a solar heat collector 1 implementing the present invention. The solar heat collector 1 includes a housing 13. During specific implementation, the outer surface of the housing 13 is streamlined (such as semicircular or ellipse), so as to reduce air resistance, and the housing 13 is internally arranged with heat-absorbing tube assemblies 10, which are spirally arranged to form a cavity 100, and one end of the cavity 100 An opening 101 is provided so that sunlight 15 collected by a solar concentrator (not shown) enters the cavity 100 from the opening 101 for absorption by the heat absorbing tube assembly 10 . In addition, the surface of the heat-absorbing pipe assembly 10 is provided with a selective absorbing coating 104, such as an electroplated black chrome layer, so that the heat-absorbing pipe assembly 10 uses the absorbing coating 104 to only absorb visible light, not infrared light, and does not emit ...

Abstract

The invention discloses a solar receiver. The solar receiver comprises a heat absorbing pipe combination, wherein the heat absorbing pipe combination is spirally arranged to form a cavity; one end of the cavity is provided with an opening for receiving intensively incident sunlight; one end of the heat absorbing pipe combination is connected with a working fluid inlet pipe while the other end is connected with a working fluid outlet pipe, wherein a heat absorbing pipe consists of a plurality of pipelines with smaller diameters; and the pipelines are connected with the working fluid inlet pipe and the working fluid outlet pipe in a parallel connection way. Therefore, heat exchange efficiency can be improved by improving the flow rate of a working fluid in the pipelines; and blackbody radiation loss of a receiver is further reduced so that heat energy absorbing efficiency is improved.

Description

【Technical field】 [0001] The invention relates to a solar receiver and belongs to the technical field of solar heat utilization. 【Background technique】 [0002] The prior art relevant to the present invention can refer to shown in U.S. Patent 4449514, and the volumetric solar receiver disclosed by it comprises a cylindrical housing, and the inner surface of the cylindrical housing is arranged with heat-absorbing pipes, and the absorbing The two ends of the heat pipe are connected to the outlet pipe and the inlet pipe of the working fluid, and one end of the shell is opened to receive the concentrated incident light. When the concentrated sunlight enters through the opening of the shell, it heats the heat-absorbing pipe working fluid, and then the heated working fluid flows out of the outlet pipe to generate steam or put into other applications. Although this kind of structure can realize the conversion of solar energy into heat energy, because the heat-absorbing tubes are a...
