1. A heat exchanger apparatus comprising:
a rigid support pedestal structure having a top, a bottom, a right side a left side, a front and a back, the pedestal structure comprising a plurality of frame members forming the pedestal structure with an open interior, the frame members defining a top air flow opening through the frame members through the top, a right side air flow opening through the frame members through the right side and a left side air flow opening through the frame members through the left side, a right frame assembly removably coupled to the pedestal structure on the right side of the pedestal structure across the right side air flow opening, a left frame assembly, removably coupled to the pedestal structure on the left side of the pedestal structure across the left side air flow opening, the right frame assembly comprising a rigid right frame with peripheral right frame members defining a right opening therebetween from an interior side of the right frame to an exterior side of the right frame, the right frame assembly further comprising at least one air to liquid or air to air right radiator each mounted to the right frame across the right opening, wherein with the right frame assembly removably coupled to the pedestal structure across the right side air flow opening, air flowing through the right opening of the right frame exchanges heat with a respective fluid within each right radiator, the left frame assembly comprising a rigid left frame with peripheral left frame members defining a left frame opening therebetween from an interior side of the left frame to an exterior side of the left frame, the left frame assembly further comprising at least air to liquid or air to air left radiator each mounted to the left frame across the opening for air flow through the left frame opening to exchange heat with a respective fluid within each left radiator, wherein with the left frame assembly removably coupled to the pedestal structure across the left side air flow opening, air flowing through the left opening of the left frame exchanges heat with fluid within each left radiator, wherein without disassembly of the pedestal structure, the right frame assembly, as an integral unit including the right frame with each right radiator fixedly secured to the right frame, is removable from and couplable to the pedestal structure, wherein without disassembly of the pedestal structure, the left frame assembly, as an integral unit including the left frame assembly with each left radiator fixedly secured to the left frame assembly, is removable from and couplable to the pedestal structure; the right side air flow opening having an exterior face directed downwardly towards the right side; the right frame assembly when mounted to the pedestal structure is disposed at an angle to the vertical with an upper portion of the right frame outwardly relative to a lower portion of the right frame assembly, a pair of front to rear spaced upper right guide members on the upper portion of the right frame assembly, a pair of front to rear spaced upper right guide arms on the pedestal structure extending laterally outwardly from the right side, each upper right guide arm having upper right-registry surfaces, the upper right registry surfaces on the upper right guide arms when engaged with the upper right guide members locate the upper portion of the right frame assembly against movement laterally and against movement downwardly, a pair of front to rear spaced lower right guide members on the lower portion of the right frame assembly, a pair of front to rear spaced lower right guide arms on the pedestal structure extending laterally outwardly from the right side to laterally beyond the upper right guide arms, each lower right guide arm having lower right registry surfaces and an upwardly directed lower right camming surface, the lower right camming surface extending from a lateral outer end to a lateral inner end, the lower right camming surface extending downwardly as it extends inwardly from the outer end to the inner end, the lower right camming surface at its inner end merging into the lower right registry surfaces, the lower right camming surfaces of the lower right guide arms when engaged by the lower right guide members urge the lower right guide members of the right frame assembly downwardly and laterally inwardly towards the pedestal support the right side into the lower right registry surfaces, the lower right registry surfaces on the lower right guide arms when engaged with the lower right guide members locate the lower portion of the right frame assembly against movement laterally inwardly to the right and against movement downwardly, when the upper right guide members are engaged with the upper right registry surfaces on the upper right guide arms and the lower right guide arms are engaged with the lower right registry surfaces on lower right guide members, the right frame assembly is in a coupled position removably mounted to the pedestal structure disposed at an angle to the vertical with the upper portion of the right frame assembly outwardly relative to the lower portion of the right frame assembly. |
