摘要:
The invention relates to an electrical heating device, especially for motor vehicles, comprising a closed frame (2) consisting of rails (3, 4) and cross rails (5, 6), heating elements (7) consisting of electrically conductive plastic layers (18) having PCT effect, which are arranged between contact plates (15, 16), heat-conducting secondary surface elements (8) that can be overflown by air and at least one electrically conductive spring element (9), wherein the heating elements (7) and the secondary surface elements (8) are alternatingly arranged next to one another and are braced against each other by means of the rails (3, 4) and a spring element (9) placed centrally which replaces the secondary surface element (8).
摘要:
A plug arrangement (8) for a heating unit having at least one PTC element, in particular for a motor vehicle. The PTC element (2) is arranged between contact plates (3, 4) which serve for the electrical connection, and one contact plate (3) is designed at one of its ends as a plug (5) which has a hollow-cylindrical shape.
摘要:
The invention relates to a heating assembly comprising at least one PTC element, in particular for a motor vehicle. According to the invention, the PTC element (2) is positioned between metal sheets (3, 4), which are used to make electrical contact, said sheets (3, 4) and the PTC element (2) are bonded by means of an adhesive (5) and the adhesive (5) has a minimum specific electrical resistance of 50 ohms×cm and a maximum specific electrical resistance of 500 ohms×cm. In addition, solder can be used as an alternative to the adhesive (5).
摘要:
The invention relates to an electrical heating arrangement, especially for a motor vehicle, said arrangement comprising an air channel housing (20) through which air to be heated flows as required, and an electrical heating clement (2) which is arranged in the air channel housing (20). The invention is characterised in that the electrical heating element (2) is arranged directly in the air channel housing (20).
摘要:
The invention relates to a heating system (1), especially for a motor vehicle, comprising at least one PTC element and a housing (7) which contains the PTC element and through which the air to be heated flows. The invention heating system also comprising a heating control device (3) which is at least partially arranged in the housing (7) and comprises at least one cooling body (6) arranged in the air stream of the air to be heated. A blower control device (5) is arranged in the housing (7), next to the heating control deice (3).
摘要:
The invention relates to a heating assembly (1) comprising at least one PCT element, in particular for a motor vehicle, said PCT element (2) being located between two contact sheets (3, 4), which are used to make electrical contact. According to the invention, the heating assembly (1) comprises a frame (7) and at least one of the two contact outside the frame (7), said staggered section of the projecting part (10) of the contact sheet (3) running parallel with the remaining part (11) of said sheet (3).
