Abstract
The present invention relates to a water-type cooling unit for a vehicle equipped with an internal-combustion engine, the unit being connected via a main circulation loop formed by appropriate conduits, in particular to at least one radiator for cooling the water or the similar coolant and to the circuits for cooling the cylinder block and the cylinder heads. Unit, characterized in that it comprises a central module in the form of a body made of thermoplastic material in which there are, in particular, mounted or partially molded a water-circulating pump and a flow-regulating valve disposed in the circulating loop, preferably between the aforementioned cooling circuits and the radiator.
Claims19
Water-type cooling unit for a vehicle equipped with an internal-combustion engine, the unit being connected via a main circulating loop (2) formed by appropriate conduits to at least one radiator for cooling a coolant and to circuits for cooling a cylinder block (4) and for cooling cylinder heads (4′), comprising a central module (5) in the form of a body made of thermoplastic material in which are at least partially integrated a water-circulating pump (6), a flow-regulating valve (7) disposed in said main circulating loop (2), and at least one valve (9, 9′, 9″) controlling supply of at least one secondary branch (10, 10′, 10″) forming a circulating circuit portion mounted in parallel on said main circulating loop (2) for connection to at least one heat exchanger (11, 12, 13), said central module (5) having a multi-layered tridimensional arrangement of its constituent parts.
