[0037] The male quick-connector 10 and female quick-connector 20 of this utility model are respectively provided with a first valve stem 103 and a second valve stem 203 for elastic positioning. This allows the male quick-connector 10 and female quick-connector 20 to remain in a closed state when not interlocked, and to maintain a closed internal channel during disassembly, automatically stopping water flow and facilitating disassembly. When the male quick-connector 10 and female quick-connector 20 are interlocked (e.g., ...), ... Figure 2 and Figure 3 As shown, the first valve stem 103 and the second valve stem 203 push against each other to open the internal channels of the male quick connector 10 and the female quick connector 20, so that the male quick connector 10 and the female quick connector 20 can be in an open state, allowing the coolant to flow within the male quick connector 10 and the female quick connector 20, so as to facilitate the delivery of coolant.
[0038] In this utility model, the optical module water-cooling heat dissipation device, after the optical module 200 is inserted into the metal housing 3, will abut against the cold plate 100, causing the cold plate 100 to be lifted upwards. Since the male quick connector 10 has a floating space A, a floating mechanism can be formed, providing a floating (moving) function. The floating space A can have a floating distance H (e.g., ...). Figure 5 As shown in the figure, the floating distance H is preferably 0.5 to 1.5 mm, and it is preferable that the floating distance H is not less than the lifting height.
