A flow distribution module with a patterned cover plate

A flow distribution module for distributing a flow of fluid over a surface to be cooled, said flow distribution module comprising:

• a housing defining at least one flow cell, each flow cell having an inlet opening arranged to receive fluid to the flow cell and an outlet opening arranged to deliver fluid from the flow cell, the flow cell(s) being positioned in such away that a flow of fluid flowing through a flow cell from the inlet opening to the outlet opening is conveyed over the surface to be cooled, each flow cell being formed to cause at least one change in the direction of flow of the fluid flowing through the flow cell,
• a cover plate arranged adjacent to the flow cell(s), said cover plate defining the surface to be cooled,
• wherein at least a part of the surface to be cooled defined by the cover plate is provided with a surface pattern of raised and depressed surface portions.
