Document Type and Number:
Japanese Patent JP2006528298
Kind Code:
A
Abstract:
In a cooling and heating device for an internal combustion engine having a main coolant pump supplying coolant to the engine and a coolant return line with a return flow control unit which directs the coolant return flow to the main coolant pump selectively via a large cooling circuit, in which an air/fluid cooler is arranged, or via a small cooling circuit bypassing the air/fluid cooler, an oil/coolant heat exchanger is provided for heating or cooling a flow of oil, the flow of coolant through the oil/coolant heat exchanger being controlled by means of a coolant flow control unit directing the flow through the oil/coolant heat exchanger only after a predefined coolant temperature has been reached so that, below this temperature, no heat is extracted from the coolant by the oil/coolant heat exchanger and rapid heating of the internal combustion engine is ensured.
