Abstract
Systems and methods for pressure expanding a tube to fit a heat exchanger fin are disclosed. The systems can include one or more pressure relief devices, and each pressure relief device can be configured to release at least some pressurized fluid via a respective auxiliary flow path in response to a pressure of the pressurized fluid being greater than a predetermined pressure relief threshold.
Claims20
A heat exchanger tube expansion system comprising:
- a tube expansion device in fluid communication with a pressurized fluid source, the tube expansion device being configured to receive pressurized fluid from the pressurized fluid source and output the pressurized fluid to an interior of each of one or more heat exchanger tubes,
- wherein the tube expansion device comprises one or more pressure relief devices, each pressure relief device being configured to release at least some of the pressurized fluid via a respective auxiliary flow path in response to a pressure of the pressurized fluid being greater than a predetermined pressure relief threshold, and
- wherein a pressure relief device of the one or more pressure relief devices is configured to detachably attach to an end of a heat exchanger tube of the one or more heat exchanger tubes.
A heat exchanger tube expansion system comprising:
- a tube expansion device in fluid communication with a pressurized fluid source, the tube expansion device being configured to receive pressurized fluid from the pressurized fluid source and output the pressurized fluid to an interior of each of one or more aluminum heat exchanger tubes,
- wherein the tube expansion device comprises a pressure relief device configured to release at least a portion of the pressurized fluid via an auxiliary flow path, which is in fluid communication with an ambient environment external to the heat exchanger tube expansion system, in response to a pressure of the pressurized fluid exceeding a predetermined pressure relief threshold,
- wherein the pressure relief device is configured to detachably attach to an end of a heat exchanger tube of the one or more heat exchanger tubes.
A heat exchanger tube expansion system comprising:
- a tube expansion device in fluid communication with a pressurized fluid source, the tube expansion device being configured to receive pressurized fluid from the pressurized fluid source and output the pressurized fluid to an interior of each of one or more aluminum heat exchanger tubes having an external diameter that is less than or equal to 7 mm,
- wherein the tube expansion device comprises a pressure relief device configured to release at least a portion of the pressurized fluid via an auxiliary flow path, which is in fluid communication with an ambient environment external to the heat exchanger tube expansion system, in response to a pressure of the pressurized fluid exceeding a predetermined pressure relief threshold,
- wherein the pressure relief device is configured to detachably attach to an end of a heat exchanger tube of the one or more heat exchanger tubes.
