Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] The appearance of the present invention is as figure 1 , which consists of figure 2 and Figure 3a components in . During manufacture, first select a nickel-based alloy wire mesh with a thickness of no more than 8mm and a mesh number of no more than 400 to make a capillary liquid-draining core 7, and weld it on the inside of the processed heat collector shell 2's rotating paraboloid. Then the bottom edge of the heat collector housing 2 is welded on the mounting edge of the heat absorber 1 bottom of the Stirling engine. In this way, the inside of the collector housing 2 has formed a clos...

Abstract

The invention discloses a high-temperature sodium heat pipe heat collector for a solar disc type thermal power generation system, which is used in the solar disc type thermal power generation system. Serving as a solar heat collector of a Stirling engine, the high-temperature sodium heat pipe heat collector plays a role in quickly transferring high-temperature heat. The heat collector has a gravity backflow type heat pipe structure, wherein the internal working medium is liquid sodium-sodium vapor. When the heat collector works, the liquid sodium packaged in a vaccumized heat pipe evaporation section absorbs focused high-temperature solar energy and is then quickly evaporated into sodium vapor. In the process, a large amount of latent heat is absorbed. The sodium vapor is condensed on the outer wall of a heat absorber tube of the Stirling engine positioned on the heat pipe condensation section, quickly releases the latent heat and becomes liquid; the liquid flows back to a liquid sodium pool along the shell of the heat collector under the action of gravity; a phase-change heat-transfer process is finished; and the process is reciprocated, and the focused solar energy is quickly transferred to the heat absorber of the Stirling engine.

Description

technical field [0001] The invention relates to a solar high-temperature sodium heat pipe heat collector used for a Stirling engine in a solar dish thermal power generation system, and mainly relates to the technical fields of concentrating solar high-temperature heat utilization and high-temperature heat pipe heat transfer. Background technique [0002] Solar dish thermal power generation technology uses a dish parabolic concentrator to collect solar energy, and then uses a Stirling engine located near its focal point as the core power machine, which can directly use the focused solar energy to output mechanical work, thereby driving its output shaft The associated generator generates electricity. The solar heat collector is located between the condenser mirror and the Stirling engine, and its function is to collect and transfer the focused solar energy to the heat absorber of the Stirling engine. This technology belongs to the field of high-temperature thermal utilization...
