A heat-exchanging device. The device comprises a block made from a heat-conducting material with a plurality of cooling tubes provided in it. Each of the cooling tubes has an inlet for receiving an inflow of a coolant fluid and an outlet for evacuating the coolant fluid, the inlet and the outlet of each cooling tubes are distributed on at least one active surface, which is substantially opposite a heat-transfer surface of the heat-exchanging device. Each cooling tube is designed to direct the coolant fluid towards and then away from said at least one heat-transfer surface. When subjected to a heat flux through the heat-transfer surface and when coolant fluid passes through the cooling tubes it absorbs heat from the block and evacuates it away. |
