[0022] like Figure 2-Figure 3 As shown, a cold plate 6 is fixed to the bottom end of the connecting assembly 4. The cold plate 6 is a hollow structure, which allows the coolant to flow into the cold plate 6 and take away the heat absorbed by the cold plate 6 during the flow.
[0023] like Figure 2-Figure 3 As shown, four groups of connection components 4 are installed on the top of each group of cold plates 6, and a delivery pipe 7 is connected between two groups of connection components 4 to facilitate the circulation of the coolant.
