Water precooling type evaporative condenser

A water precooling type evaporative condenser comprises a shell box body, an air outlet and an air inlet are sequentially formed in the shell box body, an axial flow fan is installed in the air outlet in a matched mode, a vertical partition plate is fixedly arranged in the shell box body, a first heat dissipation pipe and a second heat dissipation pipe are sequentially arranged on the two sides of the vertical partition plate, and a spraying mechanism is arranged above the second heat dissipation pipe in a matched mode. A water collecting tank is arranged at the bottom of the shell box body and is communicated and connected with the spraying mechanism through a circulating water pump; a coolant inlet and a coolant outlet are sequentially formed in the shell box body. The cooling device is simple in structure and ingenious in conception, the second heat dissipation pipe is rotationally arranged, so that cooling water is evenly sprayed to the second heat dissipation pipe, the second heat dissipation pipe is coo
