HEATING ARRANGEMENT

A heating arrangement has a coolant housing with an inflow connection and an outflow connection for a coolant. Heating elements are arranged on opposite housing walls and include connections for the supply of power. Three circuit-board pieces of a circuit board are arranged in a row and connected to one another via flexible regions. Power electronic components and connections for connecting to the power-supply connections of the heating elements are arranged on the two edge circuit-board pieces. The circuit board is bent in flexible regions such that the two edge circuit-board pieces lie opposite one another. The coolant housing lies between the opposite edge circuit-board pieces. The power-supply connections of the heating elements and the connections on the edge circuit-board pieces are in electrical contact.
