Abstract:
The invention relates to a cooling apparatus (1) comprising tubes (4) containing a plurality of channels (8), a first manifold (2) and a second manifold (3) in the second end (7) which provides a fluid path between predetermined channels (8) of the tubes (4). In order to obtain a cooling apparatus providing excellent cooling, the first (2) and second (3) manifolds are solid blocks providing channel loops (10, 11), and the channels (8) of the tubes (4) are connected by the channel loops (10, 11) to other predetermined channels (8) of the tubes (4).
