Claims19
A process for producing a retrofit heat exchanger, comprising the steps of:
- providing an existing heat exchanger originally fabricated as a gas and heat transfer fluid exchanger and having a plurality of tubes configured for heat exchange with said gas and configured within at least one of a void or a channel configured to receive said gas;
- using said existing heat exchanger in service as a gas and heat transfer fluid exchanger consistent with the original fabrication as a gas and heat transfer fluid exchanger;
- achieving in said heat exchanger at least one of a used void or a used channel receiving said gas by said using said heat exchanger in service as a gas and heat transfer fluid exchanger;
- achieving in said heat exchanger a plurality of used tubes by said using said heat exchanger in service as a gas and heat transfer fluid exchanger;
- creating a used heat exchanger by said using said heat exchanger in service as a gas and heat transfer fluid exchanger;
- ceasing said use of said used heat exchanger in service as a gas and heat transfer fluid exchanger;
- removing said gas from at least one used void or used channel;
- sealing at least one of a gas inlet having a used condition and a gas outlet having a used condition in fluid communication with at least one said used void or used channel;
- providing a phase change material or phase change material composite in a liquid state to fill an at least a part of said at least one used void or used channel;
- filling at least in part said at least one used void or used channel with said phase change material or phase change material composite covering one or more of a used tube of said plurality of used tubes at least in part with said phase change material or phase change material composite;
- closing said used void or used channel to at least in part contain said phase change material or phase change material composite;
- said closing achieving said at least one used void or used channel sealed off so as to contain said phase change material or phase change material composite within said at least one void or channel whether said phase change material or phase change material composite is in a liquid, a solid, a gas or a mixed phase;
- and producing said retrofit heat exchanger.
