Abstract
A heat exchanger including a tube having inlet ends and outlet ends and defining a flow path therebetween. The tube can have a first section and a second section arranged at an angle with respect to the first section. Each of the first section and the second section can include a first subsection and a second subsection arranged at an angle with respect to the first subsection.
Claims29
A heat exchanger comprising:
- a plurality of flattened tubes extending between first and second headers,
- each tube having an first end connected to the first header and a second end connected to the second header and defining a first flow path therebetween, each tube having a first bend and a second bend defining:
- a first section,
- a second section oriented at an angle with respect to the first section, and
- a third section oriented at an angle with respect to the second section, the first, second, and third sections being connected in series along the first flow path;
- and
- a second flow path that passes over an exterior of the tube, the tube positioned such that the second flow path passes over the first and second sections in parallel and the second flow path passes over the second and third sections in series.

A heat exchanger comprising:
- a flattened tube having an inlet end and outlet end and defining a first flow path therebetween, the tube having a fold defining a first section and a second section in series along the first flow path, the second section of the tube being at least partially nested in the first section of the tube such that a second flow path of fluid flowing around an exterior of the tubes passes the first and second sections in series.
A heat exchanger comprising:
- a plurality of flattened tubes extending between first and second headers,
- each tube having a first end connected to the first header and a second end connected to the second header and defining a first flow path therebetween, each tube having:
- a first section, and
- a second section arranged in nesting relationship with the first section,
- the first section and the second section each including:
- a first subsection, and
- a second subsection arranged at an angle with respect to the first subsection;
- and
- a second flow path that passes over an exterior of the tube, the tube positioned such that the second flow path passes over the first and second subsections of each of the first and second sections in parallel and the second flow path passes over the first and second sections in series.
