• a body having a wall, a first end, a second end, an inlet, and an outlet, wherein the first end and the second end are on opposite sides of the body from each other, and wherein the inlet and the outlet are at least partially disposed between the first and second ends;
• a cooling plate disposed within the body, wherein the cooling plate is connected to the first end, and wherein a gap separates the cooling plate and the second end;
• and
• a first liner disposed over the cooling plate, wherein the first liner is between the inlet and the cooling plate and comprises:
• a plate coupled to an end of the wall;
• and
• a plurality of fins extending from the plate and extending away from the cooling plate, wherein the plurality of fins comprises:
• a center fin forming a first angle with respect to the plate;
• a first angled fin forming a second angle with respect to the plate, the second angle is an acute angle facing the center fin;
• and
• a second angled fin forming a third angle with respect to the plate, the third angle is an acute angle facing the center fin, and the second angle is greater than the third angle.
