<p>A heat exchanger cap 30 comprising first 60 and second 62 elements, each covering one side of the head, and an intermediate element 64 joined to, and spacing apart, the first 60 and second 62 elements. Each of the elements defines a single passageway 52 for the movement of fluid through the cap. Each of the elements is also provided with a flow interface in the region 70, 72 where the elements are joined, the flow interface defining an inlet 70a, 72a for the passage of fluid into the passageway of one of the elements, and an outlet 70b, 72b for the passage of fluid from the passageway out of the same element. Also included is a method of manufacturer of the heart exchange cap, comprising pairs of formers 102, 106, 110 associated with, and defining the shape of, each element 60, 62, 64. Linking one of each pair of formers together defines a surface of the cap, with the other formers defining the other surface (102a/b with 106a/b and 110a/b).</p> |
