A heat sink (2) for an injection/metering valve (4) has a coolant chamber (8) which is designed for receiving a fluid coolant. The coolant chamber (8) has at least one inlet (14) for supplying the coolant and at least one outlet (16) for removing the coolant. The at least one inlet (14) and/or outlet (16) has a pipe segment (20, 22) which extends with one end into the coolant chamber (8). The coolant-chamber-side end of the pipe segment (20, 22) is bevelled, and therefore the coolant-chamber-side end of the pipe segment (20, 22) is in contact at at least one point along its circumference with a baffle (12) arranged in the coolant chamber (8), and the end of the pipe segment (20, 22) is spaced apart at another point along its circumference from the baffle (12).
