Heat exchanger, hardway fin arrangement for a heat exchanger, and methods relating to same

A hardway fin arrangement for a heat exchanger comprising:

• a first section of first hardway fins positionable in a body of a heat exchanger adjacent to a position at which a first fluid from a tank is fed into the body;
• a second section of second hardway fins positionable in the body such that that first hardway fins are locatable between the second hardway fins and the position at which the first fluid from the tank is fed into the body;
• the first hardway fins configured to provide a backpressure for maintenance of a fluid level of the first fluid in the tank;
• the second hardway fins configured to provide a backpressure for maintenance of the fluid level of the first fluid in the tank and facilitate fluid distribution for distributing the first fluid on a plurality of easyway fins locatable in the body of the heat exchanger such that the second hardway fins are located between the first hardway fins and the easyway fins;
• and
• the first section of the first hardway fins and the second section of the second hardway fins are positioned and configured so that a first flow resistance per unit length of the first section of the first hardway fins differs from a second flow resistance per unit length of the second section of the second hardway fins;
• wherein:
• each of the first hardway fins configured to provide the backpressure for maintenance of the fluid level in the tank by having holes in a body of the first hardway fin, the holes of the first hardway fins having a first hole pitch and a second hole pitch that define spacing between immediately adjacent holes of the first hardway fins, each of the holes of the first hardway fins having a hole diameter, the first section of first hardway fins also having a first fin frequency;
• and
• each of the second hardway fins configured to provide the backpressure for maintenance of the fluid level of the first fluid in the tank and facilitate fluid distribution for distributing the first fluid on easyway fins by having holes in a body of the second hardway fin, the holes of the second hardway fins having a first hole pitch and a second hole pitch that define spacing between immediately adjacent holes of the second hardway fins, each of the holes of the second hardway fins having a hole diameter, the second section of second hardway fins also having a second fin frequency, the second fin frequency being different than the first fin frequency.
