Cabinet with enhanced convection cooling

A cabinet for outdoor use for enclosing electronics equipment, the cabinet comprising:

• a double skin protective outer casing for enclosing the equipment, the casing comprising:
• an inner skin and an outer skin;
• a lower air intake into a cavity between the skins of the double skin of the casing and an upper air output from the cavity to the outside, defining a path for unforced cooling air to flow, to extract heat from the equipment by convection;
• and
• the inner of the skins comprising a fin extending into the cavity for promoting thermal transfer from the inner skin to the air in the cavity.

A cabinet for outdoor use for enclosing a rack of electronics equipment, the cabinet comprising:

• a double skin protective outer casing for enclosing the equipment, the casing comprising:
• an inner skin and an outer skin;
• a thermal insulation layer for insulating the equipment from external conditions;
• and
• a lower air intake into a cavity between the skins of the double skin of the casing and an upper air output from the cavity to the outside, defining a path for unforced cooling air to flow, to extract heat from the equipment by convection,
• the inner of the skins of the double skin comprising a heat sink of the rack of electronics equipment, and being provided with protrusions extending into the cavity.

A method of manufacturing a cabinet for outdoor use for enclosing a rack of electronics equipment, comprising the steps of:

• making a double skin protective outer casing comprising an inner skin and outer skin for enclosing the equipment, by:
• making a lower air intake into a cavity between the skins of the double skin of the casing and an upper air output from the cavity to the outside, defining a path for unforced cooling air to flow to extract heat from the equipment by convection;
• and
• forming the inner of the skins in part at least from a heat sink of the rack.
