| 摘要： | The military is upgrading their fleets to increase vehicle power and/or 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%. |
