Abstract
A water heater self-circulation water pump cooling water system. Because the water temperature at the outlet of the water heater is too high, the water needs to be cooled by a heat exchanger. The cooling water source is taken from a tap water pipeline and is discharged after heat exchange of the heat exchanger, so that great economic loss is caused. The utility model comprises the following components: the water supply pipeline is respectively communicated with a heat exchanger (10) of the water heater heat exchange system to supply water for the heat exchanger, and a water outlet of a water delivery tank (9) of the water heater heat exchange system is communicated with the outdoor sewage discharge cooling system through a water discharge pipeline (8); and a cooling water pipeline (4) of the outdoor sewage draining and cooling system is communicated to the water supply pipeline. The utility model is used for the self-circulation cooling of the water heater.
