确定冷却系统所要求的最小引射系数
a cooling system which use the vehicles'exhaust gas energy was studied
A design method for the ejector is proposed systematically
The design process for the vehicle cooling system is put forward
According to the theory of aerodynamics and heat transfer,the formula the ejector coefficient which is used to evaluate the ejectors' performance is derived
Take a certain type of armoed vehicle as an example,determining the minimum ejector coefficient the cooling system required through theoretical calculation,studying the impact of ejector's structure on the ejector coefficient,finding the most suitable ejector for the heavy-duty vehicle under the condition that meet the minimum ejector coefficient and the limited power carbin
