HEAT EXCHANGER WITH PRESSURIZED PLENEM Two flat radiators are arranged in a V, with a gap at the base of the V. The ends of the radiators preferably are closed off to form a plenum chamber between the radiators. A fan, preferably of the transverse flow type, is provided at the top of the radiators to pressurize the plenum chamber, which causes air to pass out through the radiator cores. The fan also directs air from the top of the V towards the gap so that debris is directed out the gap. The radiators may have a significantly higher fin density than in the conventional radiator since debris need not pass through the radiator cores. In an alternative embodiment, four radiators are arranged in a nested double V, with a gap at the base of the outermost V. Two fans, again preferably of the transverse flow type, are provided to direct air into the top of the V. Operation is similar to the single V structure, except that in low cooling requirement conditions, one of the fans may be turned off. |
