Evaporative condenser for refrigerating system

The invention belongs to the technical field of condensers, particularly relates to an evaporative condenser for a refrigerating system, and aims to solve the problem that water cannot uniformly cover a pipe wall due to the fact that a condensation calandria is complex in structure during spraying in the prior ar. The evaporative condenser comprises a box body, an air inlet pipe is fixedly connected to the outer wall of one end of the box body, a first connecting box is arranged on the inner wall of the box body, and a rotating mechanism is arranged on the outer wall of the first connecting box. Air is finally discharged from a plurality of first spraying pipes at the bottom of a liquid outlet plate, a condensation calandria at the bottom of a liquid collecting box is sprayed, finally, the air is condensed into liquid, the liquid is discharged from a liquid outlet pipe at the bottom, and a rotating mechanism is arranged to drive a first connecting box to rotate, so that the condensation calandria fixedly conn
