The pressing head 31 can press down the radiator water chamber located on the core supporting mechanism 2 under the drive of the vertical driving assembly. Specifically, the vertical driving assembly includes a first motor 32 and a first screw nut pair 33 connected to each other.

[0045] The second cylinder 26 pushes the slidable platform 27 to the left, so that the right supporting slider 23 clamps the mainboard on the radiator core.

[0046] Driven by the vertical driving assembly, the pressing head 31 of the water chamber pressing mechanism 3 presses downward the radiator water chamber located on the core supporting mechanism 2 to fix it without moving, which is convenient for subsequent pressing.

[0047] Next, the radiator water chamber and the mainboard are pressed.
