[0038] In this application, the upper water cavity cover plate and the lower water cavity cover plate are assembled to the modular body 1 by bolts, and the upper vacuum hole and the lower vacuum hole are processed by drilling on the modular body 1, which solves the inherent defects in the casting and welding processes in the prior art. The modular body 1 has high quality and there are no faults such as water leakage and air leakage.
[0039] As Figure 3 and Figure 4 shown together, for the convenience of drilling, the upper vacuum hole is divided into a first upper vacuum hole 13 and a second upper vacuum hole 14 that are connected, and the lower vacuum hole is divided into a first lower vacuum hole 17 and a second lower vacuum hole 18 that are connected. The first upper vacuum holes 13 of the two modular bodies 1 are connected, and the first lower vacuum holes 17 of the two modular bodies 1 are connected.
[0040] To make the cooling uniform, the wall thickness between the vacuum hole and the water cavity needs to be consistent.
