Abstract
Cooling apparatus for use on a vehicle. The apparatus includes a heat exchanger in which heat is removed from a heat load by a coolant, and first and second coolant supplies. The first coolant supply is adapted to receive a first coolant and to supply the first coolant to the heat exchanger. The first coolant is available during normal vehicle operations. The second coolant supply is adapted to receive a second coolant and to supply the second coolant to the heat exchanger. The second coolant is supplied by a fluid supply and is unavailable during normal vehicle operation.
Claims18
A cooling apparatus for use on a vehicle, the cooling apparatus including a heat exchanger in which heat is removed from a heat load by a coolant, wherein the cooling apparatus also includes a first and second coolant supply means, wherein the first coolant supply means is adapted to receive a first coolant and to supply the first coolant to the heat exchanger, wherein the first coolant is available during normal vehicle operation, wherein the second coolant supply means is a source of compressed air which supplies said compressed air coolant to the heat exchanger, and wherein the second compressed air source coolant is unavailable during normal vehicle operation.
A method of cooling a heat load in a vehicle using a cooling apparatus, the cooling apparatus including a heat exchanger in which heat is removed from a heat load by a coolant, wherein the method includes the steps of using a first coolant supply means to supply a first coolant to the heat exchanger when the vehicle is in normal operation not at rest, and using a second coolant supply means to supply a compressed air second coolant to the heat exchanger when the vehicle is at rest and the first coolant is unavailable or is unable to provide adequate cooling.
