A heat exchanger assembly, comprising: a frame comprising: a first leg and a second leg laterally spaced apart from the first leg; a lower transversal member extending laterally and interconnecting the first and second legs; a first upstanding member and a second upstanding member laterally spaced apart from the first upstanding member, the first and second upstanding members extending upwardly from the lower transversal member, each of the first and second upstanding members having a lower end portion and an upper end portion; an upper transversal member extending laterally and disposed above the lower transversal member; and a first upper retaining member and a second upper retaining member laterally spaced apart from the first upper retaining member, the first and second upper retaining members being connected to the upper transversal member and extending transversally to the upper transversal member; first and second heat exchanger panels for exchanging heat with air pulled into the heat exchanger assembly, each of the first and second heat exchanger panels extending from an upper end to a lower end and including a tubing arrangement for circulating fluid therein, the first and second heat exchanger panels being disposed in a V-configuration such that a distance between the upper ends of the first and second heat exchanger panels is greater than a distance between the lower ends of the first and second heat exchanger panels; and a fan for pulling air into the heat exchanger assembly via at least one of the first and second heat exchanger panels, the fan having a fan rotation axis (FA*) extending generally parallel to the first and second upstanding members of the frame, characterised in that the upper transversal member is connected to the first and second upstanding members at the upper end portions thereof; and the upper end of each of the first and second heat exchanger panels being connected to the first and second upper retaining members. a frame comprising: a first leg and a second leg laterally spaced apart from the first leg; a lower transversal member extending laterally and interconnecting the first and second legs; a first upstanding member and a second upstanding member laterally spaced apart from the first upstanding member, the first and second upstanding members extending upwardly from the lower transversal member, each of the first and second upstanding members having a lower end portion and an upper end portion; an upper transversal member extending laterally and disposed above the lower transversal member; and a first upper retaining member and a second upper retaining member laterally spaced apart from the first upper retaining member, the first and second upper retaining members being connected to the upper transversal member and extending transversally to the upper transversal member; a first leg and a second leg laterally spaced apart from the first leg; a lower transversal member extending laterally and interconnecting the first and second legs; a first upstanding member and a second upstanding member laterally spaced apart from the first upstanding member, the first and second upstanding members extending upwardly from the lower transversal member, each of the first and second upstanding members having a lower end portion and an upper end portion; an upper transversal member extending laterally and disposed above the lower transversal member; and a first upper retaining member and a second upper retaining member laterally spaced apart from the first upper retaining member, the first and second upper retaining members being connected to the upper transversal member and extending transversally to the upper transversal member; first and second heat exchanger panels for exchanging heat with air pulled into the heat exchanger assembly, each of the first and second heat exchanger panels extending from an upper end to a lower end and including a tubing arrangement for circulating fluid therein, the first and second heat exchanger panels being disposed in a V-configuration such that a distance between the upper ends of the first and second heat exchanger panels is greater than a distance between the lower ends of the first and second heat exchanger panels; and a fan for pulling air into the heat exchanger assembly via at least one of the first and second heat exchanger panels, the fan having a fan rotation axis (FA*) extending generally parallel to the first and second upstanding members of the frame,
