Patent

CA 2209286

A heating system for a vehicle is provided which does not require a large boarding space in an engine room very much, which can be manufactured at a reduced cost, and which can fully heat a passenger compartment of a vehicle when an engine is started. For instance, in the vehicle heating system, a water pump (WP) and a viscous heater (VH) is incorporated into an installation housing (1), a plate (2) and a cover (3) which are bonded to a cylinder block of an engine. The water pump (WP) and the viscous heater (VH) are driven by a drive shaft (11) which is shared by them. Moreover, the viscous heater (VH) includes an auxiliary water jacket (WJ2). The auxiliary water jacket (WJ2) is communicated with a main water jacket (WJ1) of the engine by way of a pump chamber (4) of the water pump (WP), and is further communicated with a heater core for heating a passenger compartment of a vehicle.

L'invention concerne un système de chauffage pour véhicules qui ne demande pas beaucoup de place pour son installation dans le compartiment moteur, qui peut être fabriqué à bas prix et qui permet de chauffer correctement un compartiment au démarrage du moteur. Une pompe à eau (WP) et un dispositif de chauffage utilisant l'effet de viscosité (VH) sont logés, par exemple, dans un carter (1) joint au bloc-cylidre d'un moteur, à une plaque (2) et à un couvercle (3). Le système est entraîné par l'arbre moteur commun (11). Une chemise d'eau secondaire (WJ2) du dispositif de chauffage (VH) communiquant avec une chemise d'eau principale (WJ1) du moteur par une chambre de pompage (4) de la pompe d'eau (WP) communique avec le centre du dispositif de chauffage.
