Lightweight active filter

The utility model provides a lightweight active filter with novel structural design, which comprises an active filter body and a mounting seat, a mounting plate is mounted between the inner walls of adjacent sides of the active filter body through bolts, and a condensation cavity is arranged between the outer wall and the inner wall of the bottom of the active filter body. A condensation pipe distributed in an S-shaped structure is arranged in the condensation cavity, a liquid inlet pipe, a liquid outlet pipe and an external pipe are welded to the bottom of the outer wall of the front face of the active filter body, and the liquid inlet pipe and the liquid outlet pipe are connected with the two ends of the condensation pipe respectively. According to the utility model, when cold water circulates in the heat dissipation pipe, heat dissipation can be carried out on the interiors of the mounting plate and the active filter body, the phenomenon of element damage caused by too high heat in the active filter body c
