Abstract: A cooling member for a mobile ice rink includes a feed manifold extending in a transverse direction and a discharge manifold, and a number of longitudinal pipes which extend transversely to the manifolds and can be connected at a first end to a manifold, two longitudinal pipes in fluid communication with one another at a second end via a connector, so that a fluid path is formed from the feed manifold to the discharge manifold via the two connected longitudinal pipes. In a transport position, the pipe sections are at an angle with respect to one another or are positioned on top of one another, and in an operational position the pipe sections extend in the extension of one another.
