Efficient self cooling heat exchanger
An inexpensive heat exchanger is disclosed, wherein the heat exchanger is made up of a plurality of plates and each plate has at least one channel defined in the plate. The plates are stacked and bonded together to form a block having conduits for carrying at least one fluid and where the exchanger includes an expansion device enclosed within the unit. The plates include construction to thermally insulate the sections of the heat exchanger to control the heat flow within the heat exchanger.
1. A heat exchanger comprising:
at least one plate having a first channel defined therein, the first channel having an inlet and an outlet; and
at least one insulating channel defined therein, and where the insulating channel is disposed between substantially parallel sections of the first channel wherein said heat exchanger is further comprising a second channel separate from the first channel defined by the at least one plate the second channel having an inlet and an outlet, wherein the first and second channel follow substantially parallel sinuous paths and are capable of containing two different streams, and where the insulating channel is disposed between substantially parallel sections of either the first channel or the second channel
and wherein said heat exchanger is further comprising a hole that is capable of insulation extending through the plate, thereby separating the plate into a heat exchange region and an expansion region to allow expansion of flow.
2. A heat exchanger comprising:
at least one plate having a first channel defined therein, the first channel having an inlet and an outlet; and
at least one insulating channel defined therein, where the insulating channel is disposed between substantially parallel sections of the first channel wherein said heat exchanger is further comprising at least one second plate having a second channel separate from the first channel defined by a second plate the second channel having an inlet and an outlet, wherein the first and second channel follow substantially parallel sinuous paths and are capable of containing two different streams, and where the insulating channel is disposed between substantially parallel sections of either the first channel or the second channel; and
wherein said heat exchanger further comprises a hole that is capable of insulation extending through the plate, thereby separating the plate into a heat exchange region and an expansion region to allow expansion of flow.
