ABSTRACT:
A heat exchanger including a first and second header is disclosed. The headers are linked in fluid communication by a plurality of elongated fluid tubes. In a first embodiment, the first and second headers are integrally formed as a single pipe having a partition wall extending radially across. Left and right intermediate headers are disposed laterally of the single pipe. Two groups of fluid tubes link the first header to a lower portion of the intermediate headers, and two additional groups of fluid tubes link the intermediate headers to an upper portion of the second header. In a second embodiment, the first and second headers are disposed in a spaced parallel arrangement and are approximately half the length of the left and right intermediate headers with which they are linked at an upper portion of the intermediate headers by fluid tubes. The lower parts of the intermediate headers are linked directly by a third group of tubes to complete the fluid circuit of the heat exchanger.
