Further, the plurality of spacers 211 are arranged at equal intervals. That is, the cross-sectional profiles of the channels formed between any two adjacent separators 211 in the same direction are uniform, so that when the cooling medium flows in the cooling channel 212, the flow velocity is kept uniform or not greatly different when the cooling medium walks through the curve to the channel formed by the next two adjacent separators 211, and the noise caused by unstable flow of the cooling medium is reduced.
