Apparatus for transferring cleaning bodies for a heat exchange through which can flow a cooling fluid

An improved heat exchanger through which a cooling fluid flows comprising:

• a heat exchanger having an inlet and an outlet,
• a casing having an inlet and an outlet, said inlet being connected to said outlet of the said heat exchanger,
• a sink operably connected to said casing outlet through a first openable conduit and having an outlet operably connected to said heat exchanger inlet,
• a screening system suitably positioned between said casing inlet and said casing outlet,
• a second conduit connecting said outlet of said sink with said inlet of said heat exchanger containing a pressure controllable valve, and
• a third conduit operably controlled by a pump suitably positioned between said outlet of said casing and said inlet of said space.

A method for transferring cleaning bodies through a heat exchanger comprising the steps of:

• providing a heat exchanger having an inlet, an outlet, a casing having an inlet and an outlet, said casing inlet connected to said heat exchanger outlet, a sink having an inlet and an outlet, said sink inlet connected by an openable conduit to said casing outlet and said sink outlet connected to said heat exchanger inlet by a second conduit including therein a pressure controllable valve, and a third conduit further connecting said casing and said sink and including therein a pump suitably positioned between the outlet of said casing and said inlet of said,
• providing cleaning bodies in said casing,
• activating a pump to deliver water from said casing to said sink at a predetermined pressure such that said valve in said outlet opens and cause said cleaning bodies to move through said sink outlet,
• passing said cleaning bodies through said heat exchanger but preventing the unintended return flow through said heat exchanger through selective operation of said pressure controllable valve.
