Efficient heat exchanger for refrigeration process

A heat exchanger comprising:

• a plurality of parallel heat transfer plates defining a first set of fluid channels and at least a second set of fluid channels;
• a first fluid inlet port configured to communicate with the first set of fluid channels;
• a first fluid outlet port configured to communicate with the first set of fluid channels;
• a second fluid inlet port configured to communicate with the second set of fluid channels;
• a second fluid outlet port configured to communicate with the second fluid channels;
• and
• a packed distributor located within at least one of the first fluid inlet port and the second fluid inlet port.

A method for exchanging heat, the method comprising:

• flowing a first fluid through a heat exchanger, the heat exchanger comprising:
• a plurality of parallel heat transfer plates defining a first set of fluid channels and at least a second set of fluid channels;
• a first fluid inlet port configured to communicate with the first set of fluid channels;
• a first fluid outlet port configured to communicate with the first set of fluid channels;
• a second fluid inlet port configured to communicate with the second set of fluid channels;
• a second fluid outlet port configured to communicate with the second fluid channels;
• and
• a packed distributor located within at least one of the first fluid inlet port and the second fluid inlet port, the first fluid flowing through the first fluid inlet port, the first set of fluid channels, and the first fluid outlet port;
• and
• flowing a second fluid through the second set of fluid channels, whereby heat is exchanged between the first fluid and the second fluid via the plurality of parallel heat transfer plates.
