Cooling and power input assembly

A cooling assembly for an electrical equipment having a series of thin vertically extending ventilation slots at an upper corner of the electrical equipment, comprising:

• a housing open on one side and having a fan outlet grille on the opposite side thereof, said housing having front and rear sides, and a top and bottom;
• fan means mounted in said housing for exhausting air from the electrical equipment through the ventilation slots;
• means for channelling air drawn from the ventilation slots into the open side of said housing to said fan means and toward said outlet grille,
• said means including a panel extending substantially vertically between said top and bottom and the front and rear sides of said housing, said panel having a substantially centrally located opening, and said panel being spaced back from the open side of said housing, on the other side of said fan means from said grille;
• means for holding said assembly in place with the open side of said housing against said electrical equipment for drawing air from the ventilation slots, said holding means consisting solely of:
• (1) lip means, formed as an extension of the top of said housing, for extending over and for engaging the upper surface of said electrical equipment beyond said ventilation openings, for substantially the full length of the open side of said housing to assist in the sealing of said open side of said housing around the ventilation openings;
• and
• (2) finger means extending outwardly from the open side of said assembly substantially perpendicular to said housing and substantially vertically, said fingers being thin and flat for extending into the ventilation slots, and said fingers having downwardly extending hook means for holding said housing in against said electrical equipment;
• and
• said housing being adapted for securing onto electrical equipment with its edges substantially sealing around the ventilation openings only by said fingers, said upper lip means and the weight of said housing, whereby said housing may be installed by merely setting it in place without the use of any screws, tools or the like.

• and
• means for holding said assembly in place with the open side of said housing against the electrical equipment for drawing air from the ventilation slots, said holding means including:
• finger means extending outwardly from the open side of said assembly substantially perpendicular to said housing, and said means having downwardly extending hook means for extending inside the electrical equipment and for holding said housing in against the electrical equipment.

• means including a fan mounted in said housing for exhausting air from the electrical equipment through the ventilation openings, into said housing and out through said fan outlet grille;
• means for holding said assembly in place with the open side of said housing against said electrical equipment for drawing air from the ventilation slots, said holding means including finger means extending outwardly from the open side of said assembly, and said finger means having downwardly extending hook means for extending inside the electrical equipment and for holding said housing in against the electrical equipment with the edges of said housing around said open side of said housing making engagement with the electrical equipment;
• electrical wiring means for supplying power to said fan and to the electrical equipment, connected to said housing;
• and
• switch means mounted on said housing for turning on said fan and simultaneously supplying power to the electrical equipment.
