摘要：
An electrically powered heater unit (1) comprising a positive temperature coefficient disc heater element (10) sandwiched between an electrically conductive contact element (14) and an electrically and heat conductive heat transfer element (15). A housing (5) defining a hollow interior region (9) is located on a plate member (4), and a communicating opening (3) formed in the plate member (4) communicates with the hollow interior region (9). The heat transfer element (15) is secured to the plate member (4) by retaining member (25) extending from the heat transfer element (15) engaging a rim (28) of the communicating opening (3), with the heating element (10) and the contact element (14) located within the hollow interior region (9) of the housing (5). A first connecting element (38) extends from the contact element (14) through the housing 5 for connecting to a first wire (39) of an electrical power supply for providing electrical power supply to a first abutment surface (11) of the heater element (10). A second connecting element (55) extends from the heat transfer element (15) through the housing (5) for connecting to a second wire of an electrical power supply, for providing the electrical power supply to a second abutment surface (12) of the heater element (10).La présente invention concerne une unité de chauffage à alimentation électrique (1) comprenant un élément de chauffage à disque à coefficient de température positif (10) pris en sandwich entre un élément de contact électriquement conducteur (14) et un élément de transfert de chaleur (15) électriquement et thermiquement conducteur. Un boîtier (5) délimitant une région intérieure creuse (9) est situé sur un élément plaque (4), et une ouverture de communication (3) formée dans l'élément plaque (4) communique avec la région intérieure creuse (9). L'élément de transfert de chaleur (15) est fixé à l'élément plaque (4) par un élément de retenue (25) s'étendant à partir de l'élément de transfert de chaleur (15) en
