摘要:
In order to cool the windings, core and optionally the wall of the element (1) receiving the windings (3,4) and the core (2) as effectively as possible, conducting surfaces (5, 6, 8,15) are disposed inside said element in such a way that the flow of coolant initially passes along the windings (3,4), followed by the limbs (21,22) of the core surrounded by the windings, and subsequently the other areas (23, 24, 1). Said arrangement of conducting surfaces is particularly suitable for use with transformers having superconductive windings made of HTSL conductor material. .
摘要:
The present invention relates to a method and a device (1) for cooling an arrangement (2) using a cold head (3), with a thermal cooling of the unit (2) to be cooled by means of the thermosiphon principle. At the same time, heat is conducted via a mechanical heat bridge (5), which provides a direct thermal connection from the cold head (3) to the unit (2) to be cooled.
摘要:
Electrical machine (1) comprising, as components, a stator (3) and a rotor (4) which can be rotated in relation to the stator (3), wherein the poles (14) of one component, in particular of the rotor (4), comprise superconducting coils (6) for generating a magnetic flux, wherein at least one high-temperature superconducting material block (7, 8, 9) with a heating means (10, 11, 12), which is associated with said high-temperature superconducting material block and is designed to temporarily increase the temperature of the high-temperature superconducting material block (7, 8, 9) above the critical temperature of the material of the high-temperature superconducting material block (7, 8, 9) in the superconducting coil (6), is arranged in the path of the magnetic flux.
摘要:
The invention relates to a cooling device (8, 25) for cooling a superconductor, in particular in a magnetic resonance device and/or a rotor (2) of a superconducting machine (1), wherein the superconductor and/or a component carrying the superconductor can be brought into contact with a liquid coolant (10, 27), wherein, in order to deliver the coolant (10, 27) to the superconductor and/or to circulate the coolant (10, 27) in a bath for the superconductor, use is made of a bubble pump (20, 36) arranged in a delivery line (18, 38).
