The structure includes: a fixing member 1, comprising a front panel 11 and a side panel 12, the side panel 12 being movably connected to the heatsink 3 and the front panel 11 being movably connected to the fan 4; the front panel 11 is a plate-shaped structure, with its body parallel to the connection surface of the heatsink 3, and includes a first through hole 111; the side panel 12 is fixed to the edge of the front panel 11; and a connecting member 2, comprising a back plate 21 and a power supply spring 22, the back plate 21 being parallel to the front panel 11 and fitting against the front panel 11, and the power supply spring 22 being disposed on the surface of the back plate 21; wherein the power supply spring 22 is movably connected within the first through hole 111, one end of the power supply spring 22 being electrically connected to the fan 4 and the other end being electrically connected to the heatsink 3. In this embodiment, the fan 4 and the heat sink 3 are slidably engaged via a ball bearing slide rail 5, meaning that... Figure 1 As shown, the fan 4 and the heat sink 3 are respectively provided with ball bearing slide rails 5 at both ends. The ball bearing slide rail 5 includes elastic balls and engaging grooves. The elastic balls and engaging grooves are respectively provided on the two contact surfaces of the ball bearing slide rail 5. The elastic balls are movably engaged in multiple engaging grooves.
