A cooling module comprising: first and second shroud panels (2, 3) arranged at opposing sides of the cooling module, each extending from a front of the cooling module to a back of the cooling module in a first direction and from a top of the cooling module to a bottom of the cooling module in a second direction; an L-shaped stiffener bracket (4, 5) extending between the first and second shroud panels (2, 3) at an intermediate location between the front of the module and the back of the module in the first direction and at an intermediate location between the top of the module and the bottom of the module in the second direction, the L-shaped stiffener bracket (4, 5) having a first planar wall arranged perpendicular to the first direction, a second planar wall arranged perpendicular to the second direction, and a right angle bend joining the first and second planar walls (6, 7); first and second formed corner brackets, the first formed corner bracket joining the L-shaped stiffener bracket (4, 5) to the first shroud panel and the second formed corner bracket joining the L-shaped stiffener bracket (4, 5) to the second shroud panel, each of the first and second formed corner brackets having a planar surface by which the formed corner bracket is joined to the corresponding one of the first and second shroud panels (2, 3), a first formed flange extending perpendicularly from the planar surface by which the formed corner bracket is joined to the first planar wall of the L-shaped stiffener bracket (4, 5), and a second formed flange extending perpendicularly from the planar surface by which the formed corner bracket is joined to the second planar wall of the L-shaped stiffener bracket; and one or more heat exchangers (30, 31) arranged between the first planar wall and the front of the module in the first direction and between the second planar wall and one of the top and the bottom of the cooling module in the second direction, the one or more heat exchangers (30, 31) being structurally mounted to the first planar wall to at least partially secure the one or more heat exchangers (30, 31) in the cooling module. first and second shroud panels (2, 3) arranged at opposing sides of the cooling module, each extending from a front of the cooling module to a back of the cooling module in a first direction and from a top of the cooling module to a bottom of the cooling module in a second direction; an L-shaped stiffener bracket (4, 5) extending between the first and second shroud panels (2, 3) at an intermediate location between the front of the module and the back of the module in the first direction and at an intermediate location between the top of the module and the bottom of the module in the second direction, the L-shaped stiffener bracket (4, 5) having a first planar wall arranged perpendicular to the first direction, a second planar wall arranged perpendicular to the second direction, and a right angle bend joining the first and second planar walls (6, 7); first and second formed corner brackets, the first formed corner bracket joining the L-shaped stiffener bracket (4, 5) to the first shroud panel and the second formed corner bracket joining the L-shaped stiffener bracket (4, 5) to the second shroud panel, each of the first and second formed corner brackets having a planar surface by which the formed corner bracket is joined to the corresponding one of the first and second shroud panels (2, 3), a first formed flange extending perpendicularly from the planar surface by which the formed corner bracket is joined to the first planar wall of the L-shaped stiffener bracket (4, 5), and a second formed flange extending perpendicularly from the planar surface by which the formed corner bracket is joined to the second planar wall of the L-shaped stiffener bracket; and one or more heat exchangers (30, 31) arranged between the first planar wall and the front of the module in the first direction and between the second planar wall and one of the top and the bottom of the cooling module in the second direction, the one or more heat exchangers (30, 31) being structurally mounted to the first planar wall to at least partially secure the one or more heat exchangers (30, 31) in the cooling module.
