Plate heat exchanger with liquid backflush circuit

A system comprising:

• a liquid flush circuit fluidly couplable to a liquid cooling circuit of a thermal cooling system, wherein the liquid cooling circuit includes a heat exchanger, the liquid flush circuit comprising:
• a fluid interconnection;
• and
• a filter, wherein the liquid flush circuit is configured to selectively operate in a normal cooling operation mode or in a flushing mode, the flushing mode configured to cause the cooling fluid to divert through the liquid flush circuit and the heat exchanger to cause the cooling fluid to flow through the filter after passing through the heat exchanger.

A method for backflushing a thermal cooling system containing a liquid circuit and a liquid flush circuit, comprising:

• switching a first set of valves on a first divergent section of the liquid flush circuit from a normal cooling operation configuration to a flushing configuration, wherein switching the first set of valves causes:
• a flow of liquid into a first divergent section of the liquid flush circuit;
• and
• a reversed flow of liquid into a portion of a fluid interconnection of the liquid circuit, wherein the reversed flow of liquid into the portion of the fluid interconnection of the liquid circuit produces a flushed liquid;
• switching a second set of valves on a second divergent section of the liquid flush circuit from an isolation configuration to a flush configuration, wherein switching the second set of valves causes:
• a flow of the flushed liquid into the second divergent section;
• a flow of flushed fluid through a backflush filter positioned along the second divergent section, wherein the flow of flushed fluid through the backflush filter produces filtered fluid;
• and
• a flow of the filtered fluid into the liquid circuit;
• and
• switching 1) the first set of valves from the flushing configuration to a normal cooling operation configuration, and 2) the second set of valves from the flush configuration to the isolation configuration, wherein switching the first set of valves from the flushing configuration to a normal cooling operation configuration, and the second set of valves from the flush configuration to the isolation configuration causes the thermal cooling system to selectively flow liquid through the liquid circuit.
