abstract
The size of a cooling inventory is generally designed based on which size can endure the excessive hea
load situations that occur sporadically. As a result， cooling systems are often too large for most norma
driving modes. There have been numerous efforts to downsize the automotive engine cooling system
using novel concepts and strategies. Efficient cooling in automobiles is beneficial in reducing harmfu
emissions as well as improving fuel economy. A simulation was conducted to validate the feasibility o
using a novel cooling strategy that utilized the heat load averaging capabilities of a phase chang
material (PCM). Three prototypes were designed: full-size， down-sized， and a down-sized prototype wit
a heat accumulator containing the PCM inside. When the full-size of the cooling inventory was down
sized by 30%， this smaller design failed to dissipate the peak heat load and consequently led t
a significant increase in the coolant temperature， around 25 
C greater than that in the full-size system
However， the peak heat load was successfully averaged out in the down-sized system with a hea
