Device for cleaning and maintenance of cooling fins of heat exchanger of an air conditioner

摘要

A device for the cleaning and maintenance of the cooling fins of a heat exchanger of an air conditioner unit includes a pistol-grip water nozzle having a water inlet providing a water pressure of between about 40 to about 80 pounds per square inch (about 300 cm Hg), the nozzle having a threaded outlet. The device also includes a hose adapter proportioned for securement to the nozzle outlet, the adapter having an outlet proportioned for receipt of a threaded inlet. Central to the inventive device is an elongate segment of cylindrical tubing having the threaded inlet as its inlet. The tubing segment includes a virtual vertical plane of symmetry defining respective left and right hollow semi-cylinders of the tubing, an outer lateral side of one of the semi-cylinders having an axial sequence of apertures in a line defining a right angle to the plane of symmetry, each having a diameter of between about 0.3 and about 0.6 millimeters and having respective axial separations of between about 4 and about 9 millimeters. The elongate segment of tubing is about 51 centimeters long and includes an end cap sealing and outlet thereof.
