Heat exchanger panel and method for mounting thereof to a rack structure

A heat exchanger stack comprising:

• a rack structure comprising:
• a plurality of vertical legs;
• a plurality of laterally-extending horizontal members extending between and interconnecting laterally-adjacent ones of the vertical legs;
• a plurality of longitudinally-extending horizontal members extending between and interconnecting longitudinally-adjacent ones of the vertical legs;
• a plurality of lower wheel guiding members, each lower wheel guiding member having a horizontal portion extending horizontally and an angled portion that is angled relative to the horizontal portion;
• and
• a plurality of upper wheel guiding members vertically spaced from the lower wheel guiding members, each of the upper wheel guiding members extending at least partly horizontally;
• and
• a plurality of heat exchangers supported by the rack structure, the heat exchangers being disposed above one another, each heat exchanger comprising:
• a fan assembly mounted to the rack structure, the fan assembly comprising a fan impeller rotatable about a fan rotation axis extending horizontally;
• and
• a heat exchanger panel mounted to the rack structure, the heat exchanger panel comprising:
• a frame having an upper end and a lower end opposite the upper end;
• a tubing arrangement supported by the frame and configured to circulate fluid therein, the tubing arrangement having an inlet and an outlet;
• a plurality of fins in thermal contact with the tubing arrangement, the fins being spaced apart from one another for air to flow therebetween and through the heat exchanger panel;
• and
• a plurality of wheels mounted to the frame, each of the wheels being rotatable about a respective axis extending generally laterally, the wheels being configured to engage respective ones of the lower and upper wheel guiding members of the rack structure for guided mounting of the heat exchanger panel on the rack structure, the wheels including:
• an upper set of wheels mounted to the upper end of the frame, the upper set of wheels including a first upper wheel and a second upper wheel spaced apart from one another;
• and
• a lower set of wheels mounted to the lower end of the frame, the lower set of wheels including a first lower wheel and a second lower wheel spaced apart from one another,
• each upper wheel engaging a corresponding upper wheel guiding member and each lower wheel engaging the horizontal portion of a corresponding lower wheel guiding member so that the heat exchanger panel is translatable horizontally.
