Description

Technical Field

[0001] The utility model relates to the technical field of coolers, in particular to an energy-saving evaporative cooler. Background Art

[0002] An evaporative condenser, also known as an evaporative cooler or a cooling (condensing) device, is a piece of equipment that uses the heat absorption of the partial evaporation of the spray water outside the coil to cool the high-temperature gaseous refrigerant inside the coil, gradually cooling the refrigerant inside the pipe from the gaseous state to the liquid state. A kind of energy-saving and environment-friendly composite evaporative cooler proposed in the prior art publication number CN210892791U includes a housing. The bottom of the left side of the housing is fixedly connected with a pump seat, the top of the pump seat is fixedly connected with a water pump, the front of the water pump is fixedly communicated with a water suction pipe, one end of a connecting water pipe is fixedly communicated with the top end of the water pump, and the other end of the connecting water pipe passes through the housing and extends into the interior of the housing. However, the spray holes at the bottom of the nozzle maintain a constant large area and large flow rate of spraying. When the temperature of the medium to be cooled is relatively low and the required heat exchange amount is small, too many water droplets sprayed by the nozzle and some of them do not evaporate and fall back into the water tank, additionally consuming the kinetic energy of the water pump, resulting in poor energy-saving effect. Without corrugated packing, the water purification effect is poor. The filter screen plate is fixedly installed inside the housing. After long-term use, its filtering effect will deteriorate, resulting in more impurities in the water and easily blocking the water pump nozzle. Summary of the Utility Model
