Abstract

The invention provides an energy-saving water pump, and relates to the technical field of water pumps. The energy-saving water pump comprises a water pump main unit and further comprises a water outlet heat dissipation mechanism which is connected with a water outlet of the water pump main unit through a water outlet connecting flange, wherein the water outlet heat dissipation mechanism comprises a water outlet pipe and a rear shell which is fixed at the rear part of the water pump main unit, a spiral heat dissipation hole is formed in the rear shell, and a filter screen is fixed at the rear end of the rear shell. The technology has the greatest advantage that the water pump water pressure is fully utilized to drive the air cooling and water cooling dual heat dissipation, so that zero extra energy consumption is realized. The split water flow drives the water wheel to generate air cooling, then enters the spiral pore canal to realize water cooling, and finally the cooling water is recycled to form an energy-saving closed loop. The whole device has compact structure, adjustable heat radiation intensity, and the rear shell can be quickly disassembled for convenient maintenance, so that the use cost is greatly reduced while the heat radiation efficiency and the operation reliability are improved.
