Heat exchange manifold

A heat exchanger comprising a pair of manifolds which are spaced apart and substantially parallel;

• a plurality of tubes interconnecting the manifolds, the tubes being spaced apart, substantially parallel, and inserted through slots in the manifolds;
• an inlet tube connected to one of the manifolds;
• an outlet tube connected to one of the manifolds;
• a mounting bracket attached to each manifold;
• and a stop member positioned inside each manifold adjacent the slots which acts as an abutment for the inserted tubes;
• wherein each manifold with associated bracket and stop member is formed in one piece;
• and wherein each manifold with associated bracket and stop member is formed by rolling of a sheet of material to form the manifold with a longitudinal edge of the sheet positioned inside the manifold to define the stop member, and with a portion of the sheet directed away from the manifold substantially at a tangent thereto to define the mounting bracket.
