Abstract
Abstract A heat transfer system disposed between a heat-emitting zone or heat source and a heat-consuming zone or heat sink in accordance with the heat pipe principle. A vacuum-tight hose conduit is arranged between the heat-emitting zone and the heat-consuming zone at least along a partial region of a heat transfer path. The respective ends of the vacuum-tight hose conduit are threadedly connected in the heat transfer path with the vacuum-tight hose conduit being resistant to the heat transfer medium and being provided with an internal capillary structure for enabling a return of the condensate.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
100 words
A heat transfer system for transferring heat between a heat-emitting means and a heat-consuming means in accordance with a heat pipe principle, characterized in that a vacuum-tight hose conduit means is arranged between the heat-emitting means and the heat-transfer means for communicating the respective means with each other, a longitudinally-extending groove structure is disposed interiorly of the hose conduit means for supporting the hose conduit means against excessive external pressure and for providing an internal capillary structure, and in that a threaded connection means is provided for connecting respective ends of the hose conduit means into a heat transfer path.
Claim 2
Dependent Claim
100 words
A heat transfer system for transferring heat between a heat-emitting means and a heat-consuming means in accordance with a heat pipe principle, characterized in that a vacuum-tight hose conduit means is arranged between the heat-emitting means and the heat-transfer means for communicating the respective means with each other, a longitudinally-extending groove structure is disposed interiorly of the hose conduit means for supporting the hose conduit means against excessive external pressure and for providing an internal capillary structure, and in that a threaded connection means is provided for connecting respective ends of the hose conduit means into a heat transfer path.
Claim 3
Dependent Claim
31 words
A heat transfer system according to claim 1, characterized in that the hose conduit means is fashioned of a material resistant to a heat transfer medium of the heat transfer system.
Claim 4
Dependent Claim
44 words
A heat transfer system according to claim 1, characterized in that a hermetically-sealable opening is provided for one of filling and venting of the heat transfer system, the hermetically-sealable opening is arranged in an area of one of the heat-emitting means and heat-consuming means.
Claim 5
Dependent Claim
22 words
A heat transfer system according to claim 3, characterized in that a pointed sealing means is provided for sealing the hermetically-sealable opening.
Claim 6
Dependent Claim
46 words
A heat transfer system according to claim 3, characterized in that a capillary means is arranged at the hermetically-sealable opening, and in that the sealable opening means is sealed by one of a pinching off and melting of the capillary means arranged at the sealable opening.
Claim 7
Dependent Claim
33 words
A heat transfer system according to one of claims 1, 2, 3, 4, or 5, characterized in that at least a portion of the hose conduit means is formed of a heat-insulating material.
