According to the performance curve ofcooling fan and resistance curveofradiator, theoperating pointof the fan and the flow velocityweredecided. According to the preparedprogram, theheatcapabilityof the cooling system is calculated, and theresultwillbecom- paredwith the testresul.t Reference for improving thecurrentcalculationmethodof theheatrejection ability isprovided. 5M Z 0 引言 “d m1 U b B _7, -5F AF ; b b_4 b , | -9 , A V{ b m1 “d Uim “ - r qB50P, { q M,y N YV “d v b0 ,7 O ,M1.d l,yN “d4 1 p b s , g A BV10e b 1 发动机冷却系统组成与控制 “d1 a0 [ ,1qF, m2 U b AV Q , ,4 b 5 99 [ bW, | j 1 p ,, h a b Z “ 19 Z 2010101 d ,yN “d 0 4,7 I n { Y b , e0 b| A g e65 eP, g e 75 eP b m2 “dm 75eP,yNYV ].d / rrTM1, L9 V ]9 3 5P b ,5 ]lBs,7 7, v]1P b yN,v95l 1YV { F gB { b QL ,F g{ ,Q5{ b{ F gB[/ , g, m g, bQ{ , YV H | , E 7h 79F Q 7 q J, “ -A[ X P b 6 结语 F g ,qT B q, “d bB a aZEZ t ] 9 bi4 9Z 7 e 9X b ID 1 E . /[M].
