When the plurality of cooling members are connected, each cooling member 110 and the fixing member 210 can be fixedly connected by the bolt to realize the fixed connection of the plurality of cooling members 110 and the fixing member 210. Since each cooling member 110 is fixedly connected to the fixing member 210 by the bolt on both sides along the second direction y, each cooling member 110 can be fixed between the fixing members 210 arranged at intervals along the second direction y to improve the fixing effect of the cooling member 110 and the structural stability of the cooling assembly 100. Since the damping assembly 300 is arranged between at least part of the cooling member 110 and the bolt connected thereto, the damping assembly 300 can isolate at least part of the cooling member 110 and the bolt connected thereto to reduce the possibility of resonance between the bolt and the cooling member 110 during operation and improve the connection stability between the bolt and the cooling member 110. Therefore, the cooling device can optimize the fixing mode of the cooling assembly 100 and improve the fixing reliability of the cooling assembly 100.
