Cleaning tool for between layered radiators and/or heat exchangers or other confined spaces

Abstract

This simple, inexpensive cleaning tool consisting of a partially flattened tube with a spade or wedge shape guiding tip, and holes, slots or nozzles on one or both flattened sides can be inserted between heat exchangers or radiators as used on motor vehicles or can be used in other limited access areas. The tube can be connected to a pressurized liquid or gas source for cleaning or coating in confined spaces such as the stacked heat exchangers, radiators, as described above, but also electric motors or electrical panels, appliances, computers and so forth, eliminating the need for time consuming and expensive disassembly. The device can be made of a variety of materials, and in a variety of lengths and widths depending on pressure needed, type of equipment being cleaned and fluids or gases being used. Equipment cleaned in this manner can be returned to optimal service quickly and cheaply. This device creates a new family of simple tools much as hammers, screw drivers, blow guns or wrenches each represents a family of tools. Each of these families may be made in different sizes or from different materials as necessary for the job being done. The same is true for this new device.

1 . A multipurpose hand held cleaning tool
 (a) having as its essence a very thin tube, with right angle holes, slots, nozzles or other perforations allowing it to be inserted in extremely narrow areas, particularly as used in vehicular radiators or heat exchangers which are commonly stacked in a single air stream whereby the tool can be used to clean or coat such hard to reach narrow areas and also other confined spaces such as electronic equipment and/or appliances, and electric motors etc. that would otherwise require disassembly for cleaning, coating or treating with liquids or gases and are difficult or impossible to clean with other commonly available tools   (b) comprising a hollow rod, tube or wand partially flattened with holes, slots or nozzles on one or both sides,   (c) said hollow rod, tube or wand sealed at leading end into a wedge shape facilitating insertion into limited access areas,   (d) said hollow rod, tube or wand fitted with a standard thread at input end to allow pressurized liquid and gas connectors, valves, eductors etc. in general use to be attached to said rod, tube or wand,   (e) said tool can be made of a variety of materials such as metal, plastic, glass etc. and in a variety of lengths and widths as appropriate to the equipment to be cleaned   (f) said tool may be manufactured with valves, connectors etc permanently attached if appropriate to a given unique situation
