The partition walls may be curved tortuously such that each of the flow channels comprises wide portions and narrow portions. The wide portions and the narrow portions may be arranged alternately in each of the flow channels in a direction along which the coolant flows. A number of the cooling fins located in each of the wide portions may be greater than a number of the cooling fins located in each of the narrow portions.
