Abstract

The invention relates to a heat-conducting device (10) for accommodating a heat-transfer medium for a planar absorber of a solar thermal collector, comprising a first header (11) for feeding the heat-transfer medium and a second header (12) for removing the heat-transfer medium, wherein the headers (11, 12) each have at least one lateral opening (16), by means of which said headers are connected to a cavity (13), wherein the cavity (13) is formed in a one-piece plastic body (14), and wherein the two headers (11, 12) are enclosed in the plastic body (14). The invention further relates to a method for producing such a heat-conducting device (10).

Description

technical field [0001] The invention relates to a heat conducting device for an absorber according to the preamble of claim 1 and a method for producing a heat conducting device according to claim 6 . Background technique [0002] Solar collectors are generally known. They usually have a relatively flat and large-area absorber plate that receives energy in the form of light, converts it into heat and releases it to a heat-carrying medium that flows through the absorber plate . [0003] Various embodiments of such solar collectors are described in the prior art. Usually, the heat conduction device with multifaceted structure has a first collecting pipe for introducing the heat transfer medium and a second collecting pipe for leading out the heat transfer medium connected to the first collecting pipe through one or more hollow chambers or pipes. Two collecting pipes, wherein in particular the cavities or ducts are in heat-conducting contact with the absorber plate and thus ...
