Definitions

  • switch heating has its purpose such that during winter the switch can be switched without problems: sticking of parts due to frost is prevented; similar problems can arise due to snow.
  • Prior art installations operate with a gas burner pipe mounted to the side wall (web) of the rail and gas flows within said pipe and is burned (see e.g. EP0014485A1 or NL1015323/Heatpoint ). Or with a by a gas burner or geothermal heated liquid flows through an against the rail clamped channel (see e.g. NL1022069C1 / EP1262597B1 /Railconsult or EP1645688A3/Scharrenbroich ). Or an electrical heating lint is mounted to the rail (see e.g. AT10906U1/Scharrenbroich ).
  • a liquid channel is provided by welding a vertical sheet to the top side of the rail toe and the lower side of the rail head ( fig. 1 /fig. 9) or two liquid pipes are mounted to the rail web, the one on top of the rail toe, the other against the lower side of the rail head (e.g. fig. 12).
  • a heating body is provided by a thin walled, angular extrusion profile mounted partly against the side and partly against the lower side of the rail head.
  • WO2009/109664 A discloses an aluminium profile in which separate supply and exhaust channels of the switch heating are clamped within along the length extending grooves in the profile.
  • the object of the invention is versatile and relates to e.g. one or more of the following: optimised efficiency, optimised even transfer of heat/cold, applicable to two or more rail types (e.g. UIC60 or UIC 54), modular construction, simple coupling.
  • the proposal is a heating / cooling element (further: heating element) of elongated shape, mounted along a rail such that there is contact across a large surface between the surface of the heating element and the surface of one or more of the rail web, the top of the rail toe and the lower side of the rail head and through which heating element one or more separated liquid channels extend longitudinally to extend parallel to the rail.
  • heating / cooling element of elongated shape
  • the heating element has one or more of the following features, preferably related to the operating attitude in which the heating element is mounted against the rail (the numbers refer to the drawing): fits tightly in the one attitude (side 1) to the one type and in the other attitude, e.g. upside down (side 2) to another rail type, wherein preferably in both attitudes a liquid channel (4) is located close to the rail web and/or rail head; fits below the rail head, next to the rail web and above the rail toe; fills substantially the space below the rail head that is sideways limited by the rail web and the vertical tangent to the rail head; is completely below the rail head; liquid channels are diagonally located and/or liquid channels are separated by a diagonal intermediate bulkhead; in side view two or more liquid channels at least partly overlap, wherein preferably in the overlap the top liquid channel is closer to the rail or rail web; one or each liquid channel (4, 5) is provided, viewed in the section perpendicular to the flow direction of the liquid through the channel (further: viewed in cross section), by a central part of
  • the heating element shown in an attitude wherein the rail 6 is located to the right of the heating element.
  • a stud as part of a coupling can be easily clamped.
