Abstract
Abstract The armored vehicle has a closed body comprising at least one internal engine equipped with a cooling system comprising at least one heat exchanger for the cooling fluid. The heat exchanger is constituted by at least one compartment housed inside the body of the vehicle and bounded in part by a conductive wall belonging to the body as an armor element. The removal of the major portion of the heat given up by the cooling fluid is effected through this wall. A conventional heat exchanger with ambient air cooling can also be provided. This conventional heat exchanger is isolated and rendered inoperative by a valve when the vehicle is in an operational situation or when its body must be entirely sealed with respect to the ambient medium.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
Armored vehicle with a closed body comprising at least one internal engine equipped with a cooling system comprising at least one heat exchanger for cooling the fluid circulating in said system, said heat exchanger being constituted by at least one compartment housed inside the body of the vehicle, a fluidtight conductive wall of said body constituting an externally flat armor element and bounding said compartment in part, said compartment being adapted to be traversed by said fluid and said conductive wall being adapted to effect the removal directly to the exterior of the body of the major portion of the heat given up by said fluid, comprising in addition, a conventional heat exchanger with ambient air cooling, means being provided to isolate and render inoperative this conventional heat exchanger when the vehicle is in an operational situation where its body must be entirely sealed with respect to the ambient medium.
Claim 2
Dependent Claim
150 words
Armored vehicle with a closed body comprising at least one internal engine equipped with a cooling system comprising at least one heat exchanger for cooling the fluid circulating in said system, said heat exchanger being constituted by at least one compartment housed inside the body of the vehicle, a fluidtight conductive wall of said body constituting an externally flat armor element and bounding said compartment in part, said compartment being adapted to be traversed by said fluid and said conductive wall being adapted to effect the removal directly to the exterior of the body of the major portion of the heat given up by said fluid, comprising in addition, a conventional heat exchanger with ambient air cooling, means being provided to isolate and render inoperative this conventional heat exchanger when the vehicle is in an operational situation where its body must be entirely sealed with respect to the ambient medium.
Claim 3
Dependent Claim
25 words
Armored vehicle according to claim 1, wherein the engine housed in the body of said vehicle is an engine for the propulsion of said vehicle.
Claim 4
Dependent Claim
28 words
Armored vehicle according to claim 1, wherein said vehicle is amphibious and the conductive wall is situated so as to be immersed when the vehicle moves in water.
Claim 5
Dependent Claim
20 words
Armored vehicle according to claim 1, wherein said conductive wall forms part of the lower body portion of the vehicle.
Claim 6
Dependent Claim
18 words
Armored vehicle according to claim 1, wherein said conductive wall forms part of the floor of the vehicle.
Claim 7
Dependent Claim
19 words
Vehicle according to claim 1, wherein the exchanger involving the wall of the body of the vehicle is flat.
Claim 8
Dependent Claim
36 words
Vehicle according to claim 1, wherein said at least one exchanger is formed partly by an element of the body of the vehicle and by a curved metal sheet fixed by its edges to said element.
Claim 9
Dependent Claim
71 words
Armored vehicle according to claim 1, wherein the conventional heat exchanger is arranged to play the role of a main exchanger and said at least one heat exchanger involving the wall of the body is connected as a branch line of the cooling system, a valve device being provided to direct the whole of said fluid through said exchanger involving the wall of the body when the main exchanger is inactivated.
Claim 10
Dependent Claim
39 words
Vehicle according to claim 8, wherein said exchanger involving the wall of the body is formed partly by an element of the body of the vehicle and by a curved metal sheet fixed by its edges to said element.
