Abstract
Abstract A ceiling element for a heating and cooling ceiling, having a pipe (3) and a ceiling panel (1), comprises, for the purpose of producing good heat-conducting contact between these parts, a contact element (4), which is formed by bending sheet metal, consisting, for example, of a copper alloy, and a guide channel (5) which is open at the bottom and by means of which the contact element is snap-fitted onto the pipe (3). Provided on each of the two side borders of the contact element (4) is a row of contact fingers (6) which are produced by punching or chemical milling, are designed as thin elastically deformable strips, project downwards and outwards, fit snugly against the upper side of the ceiling panel (1) in each case and rest closely up against said ceiling panel even if it has irregularities.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
88 words
A contact element for providing heat transfer from a heat transfer medium to a ceiling, said contact element comprising: a guide for holding, in heat-conducting contact, a conduit through which heat transfer medium flows; and a contact surface for making contact with a ceiling panel, at least part of said contact surface including a plurality of contact fingers for contacting the ceiling panel and moveable relative to each other, said contact fingers comprising a deformable material and being arranged alongside one another in heat-conducting connection with the guide.
Claim 2
Dependent Claim
88 words
A contact element for providing heat transfer from a heat transfer medium to a ceiling, said contact element comprising: a guide for holding, in heat-conducting contact, a conduit through which heat transfer medium flows; and a contact surface for making contact with a ceiling panel, at least part of said contact surface including a plurality of contact fingers for contacting the ceiling panel and moveable relative to each other, said contact fingers comprising a deformable material and being arranged alongside one another in heat-conducting connection with the guide.
