The military is upgrading their fleets to increase vehicle power andor to add more capabilities communication, control, and sensing equipment to aid in completing the mission. Future military combat vehicles are focused on increasing the overall power-pack power density these changes increase the cooling demand on military vehicles. However, as the power-pack increases in power, the allocated space claim for the cooling system has not increased, resulting in an overburdened cooling system. This results in a platform that is unable to meet its mobility requirements. One possible solution is to increase the heat exchanger effectiveness allowing for an increase in heat rejection while minimizing impact on space, weight, and cost allocation. The objective of this topic is to assess, develop, and evaluate a more effective heat exchanger technology that increases thermal and aerodynamic performance while minimizing the impact on weight, cost, and durability. Table 1 in the example military heat exchanger performance shows the space claim, boundary conditions and performance requirements for 3 typical heat exchangers that would be configured into a heat exchanger pack. Chart 1 in the example military heat exchanger performance shows the typical air flow sensitivity to heat exchanger air-side restriction. TARDEC wants to investigate heat exchanger technologies that meet or exceed the thermal and aerodynamics performance targets shown in Table 1 by 5.
