Abstract
A cooling system including a first sheet steel item having a first surface configured to accommodate one or more objects to be cooled, and a second surface joined to a first surface of a second sheet steel item forming a shell. The items may be joined by a weld, a rivet or a plurality thereof. At least one of the second surface of the first sheet steel item and the first surface of the second sheet steel item may be formed to produce one or more conduits for forming one or more channels, whereby said joining forms said channels for coolant in a space between the second surface of the first sheet steel item and the first surface of the second sheet steel item.
Claims16
A cooling system comprising:
- a first sheet steel item having a first surface configured to accommodate one or more objects to be cooled, and a second surface;
- and
- a second sheet steel item forming a shell,
- wherein the second surface of the first sheet steel item is joined to a first surface of the second sheet steel item, and
- at least one of the second surface of the first sheet steel item and the first surface of the second sheet steel item have been formed to produce one or more conduits for forming one or more channels, whereby said joining forms said channels for coolant in a space between the second surface of the first sheet steel item and the first surface of the second sheet steel item, said channels comprising:
- one or more inlet manifolds for coolant,
- a number of outlet manifolds for coolant, wherein the number of outlet manifolds is equal to one more than the number of inlet manifolds,
- whereby each channel is connected to one or more inlet manifolds and one or more outlet manifolds, and
- wherein the conduits comprise bends, an outer side and an inner side of each conduit each have a first radius of curvature in a crossflow direction in an upstream end of the bend and a second radius of curvature in a crossflow direction in a downstream end of the bend, the first radius of curvature of the outer side is larger than the second radius of curvature of the outer side and the first radius of curvature of the inner side is larger than the second radius of curvature of the inner side, and a curvature of the outer side and a curvature of the inner side of each conduit are each asymmetrical about a longitudinal axis of the bend.
