1. A heat exchanger for thermal management systems for the feeding of fuel in internal combustion engines (M) internally provided with a cooling water circuit, having an inlet, connected to an outlet of a water radiator, by means of a cooled water conduit, external to the engine (M), and an outlet connected to the water radiator by means of a hot water conduit external to the engine (M); and with a lubricant oil circuit having an inlet and an outlet, wherein the heat exchanger (HE) comprises an inlet and an outlet of water, respectively connected, in series, to the outlet of the water radiator, by means of the cooled water conduit and of the cooling water circuit, and with the inlet of the water radiator, by means of a return conduit and through the hot water conduit; a fuel inlet nozzle and a fuel outlet nozzle, selectively connected, in parallel, to the fuel supply to the engine (M); and an inlet and an outlet of lubricant oil, respectively connected to the outlet and to the inlet of the lubricant oil circuit by means of respective oil conduits, wherein: the fuel inlet and outlet nozzles are provided at one side of the heat exchanger (HE) other than the side of the heat exchanger (HE) in which are provided the inlet and outlet of water and the inlet and outlet of lubricant oil; and the heat exchanger is mounted to a support (S), for fixation to the engine (M) or to a structure for installing the engine (M), and defined by a flange, against one side of which is seated and fixed the heat exchanger (HE), said flange presenting through holes, in which are respectively defined the inlet and outlet of water and the inlet and outlet of oil.
