Heat sink for an injection/metering valve

A heat sink (2) for an injection/metering valve (4) comprising

• a coolant chamber;
• a baffle (12) arranged in the coolant chamber (8);
• an inlet pipe segment having a coolant-chamber end of the inlet pipe segment that extends into the coolant chamber to provide a fluid coolant to the coolant chamber, wherein the coolant-chamber end of the inlet pipe segment (20) is beveled such that the coolant-chamber end of the inlet pipe segment (20) is in contact with the baffle at at least one point along a circumference of the coolant-chamber end of the inlet pipe segment, and the coolant-chamber end of the inlet pipe segment (20) is spaced apart from the baffle at another point along the circumference of the coolant-chamber end of the inlet pipe segment;
• and
• an outlet pipe segment having a coolant-chamber end of the outlet pipe segment that extends into the coolant chamber (8) to discharge the fluid coolant from the coolant chamber, wherein the coolant-chamber end of the outlet pipe segment (22) is beveled such that the coolant-chamber end of the outlet pipe segment (22) is in contact with the baffle at at least one point along a circumference of the coolant-chamber end of the outlet pipe segment, and the coolant-chamber end of the outlet pipe segment (22) is spaced apart from the baffle at another point along the circumference of the coolant-chamber end of the outlet pipe segment.
