The metal shell of the vacuum coating equipment is fixed on the outer wall of the vacuum coating machine through the installation of the hole, and the outer wall to be cooled is formed by strengthening the round groove. Thus ensures the circulation of the cooling water and avoids the occurrence of the dead angle, reduces the temperature of the coating machine quickly, reduces the temperature of the oil pump, strengthens the strength of the cooling, and has the advantages of simple structure, safety and reliability and good cooling effect.
The vacuum coating machine circulating cooling system uses a cooling shell, which includes a metal shell, and characterized in that the metal shell with a plurality of well-arranged and well-ordered hemispherical or truncated cone-shaped concave circular grooves. The vertical and horizontal pitch of the round groove is 100-300mm, depth is 12-15mm, thickness is 2-5, and maximum diameter is 24-136mm.
At the bottom of the reinforcing round groove, a mounting hole is installed to connect the cooling outer wall of the existing vacuum coating machine. The metal shell is fixed to the cooling outer wall of the existing vacuum coating machine through the mounting hole and is welded. Between the metal shell and the outer wall to be cooled the circular channel is formed by strengthening the round groove.
