Abstract

The invention relates to the field of solar application, in particular to a detachable-type solar phase-changing heat collection-storage heat exchanging tube, which comprises a solar heat collection tube (100), a phase-changing heat collection tube (200) and a heat exchanging tube (300), wherein the phase-changing heat collection tube (200) is arranged inside the solar heat collection tube (100), and the heat exchanging tube (300) is arranged inside the phase-changing heat storage tube (200). The detachable-type solar phase-changing heat collection-storage heat exchanging tube has the effects that the phase-changing heat storage tube can be completely separated from the heat exchanging tube, so that the phase-changing material can be completely separated from the heat exchanging medium, and the solar phase-changing heat storage tube has an overheat unloading function; and meanwhile, the temperature inside the solar tube is stabilized, and the heat absorption efficiency of the solar tube is increased.

Description

technical field

[0001] The invention relates to the field of solar energy utilization, in particular to a separated solar phase change heat collection heat storage heat exchange tube. Background technique

[0002] At present, the solar collectors used to provide civil hot water or heating are mainly vacuum tube collectors and flat plate collectors, especially the most widely used vacuum tube collectors, which have relatively high heat collection efficiency and low heat collection temperature. It is also relatively high, and the heat loss is relatively small.

[0003] In addition, due to technical problems, the solar heat collection of vacuum tube collectors is generally not collected and used, and heat storage devices are often required. At present, most solar heat storage devices are solar hot water storage tanks, and water heat storage mainly depends on the sensible heat storage of water. Heat, solar water storage tanks often require a larger volume. The solar water tank...
