Abstract (en)
[origin: EP1545157A2] Method for clamping PTC heating elements etc. in hollow holder (1), such as tube, with two concave ceiling wall region (1.5,1.6) opposite to each other and to flat sides of PTC heating elements (2). PTC heating elements are clamped by pressure application to further side walls, orthogonally to ceiling wall regions. Preferably side walls are pressurised in direction of their surface normal. Pressure application typically reduces spacing of side walls in application direction, with regions of side walls providing clamping of PTC elements. Independent claims are included for tube holding PTC heating elements and its use and heater.
