| 摘要 |
The invention relates to a device for temperature controlled heating of a fluid line which comprises a jacket conduit made of a flexible material and provided with a longitudinal slot across which a fluid line is insertable into a cavity of said jacket conduit, at least one heating element extending in longitudinal direction of said jacket conduit and one temperature sensor each arranged in a first and a second section of the jacket conduit, wherein at both sides of a longitudinal center plane (M) extending through the longitudinal slot ( 5 ) the jacket conduit ( 1, 21 ) is provided with at least one circumferential section ( 7, 8, 22, 23 ) having a plurality of continuous longitudinal channels ( 9, 9', 10, 10', 13, 13', 13'', 26, 26' ) and/or intermittent longitudinal channels ( 13, 13', 13 '') adapted to accommodate at least two heating elements ( 11 ) and/or at least one temperature sensor ( 14, 15 ), said continuous longitudinal channels ( 9, 9', 10, 10', 13, 13', 13'', 26, 26' ) and/or intermittent longitudinal channels ( 13, 13', 13 '') extending symmetrically to said longitudinal center plane (M) of the jacket conduit ( 1, 21 ) and/or to a center plane of said circumferential section ( 7, 8, 22, 23 ).
