Abstract
A heat exchanger includes aligned tubes and upper and lower header tank units, each of which includes two fluid conduits communicated with the tubes. Each header tank unit further includes an intermediate plate, which defines a plurality of communication holes therethrough. Each communication hole communicates between a corresponding one of the tubes and a corresponding one of chambers defined by the fluid conduits of the header tank unit such that each tube is spaced apart from the corresponding one of the chambers.
Claims20
A heat exchanger for exchanging heat between internal fluid inside the heat exchanger and external fluid outside the heat exchanger, the heat exchanger comprising:
- a plurality of aligned tubes which are arranged one after another in an aligning direction;
- and
- at least one header tank unit, each of which includes:
- a plurality of fluid conduits which extend parallel to the aligning direction of the plurality of tubes and which are in communication with the plurality of tubes;
- and
- a communication hole defining means for defining a plurality of communication holes therethrough, wherein:
- each communication hole communicates between a corresponding one of the plurality of tubes and a corresponding one of the plurality of fluid conduits of the header tank unit such that each tube is spaced apart from the corresponding one of the plurality of fluid conduits;
- one of the plurality of fluid conduits of the header tank unit is directly in communication with one of predetermined adjacent two of the plurality of tubes through a corresponding one of the plurality of communication holes and is not in communication with the other one of the predetermined adjacent two of the plurality of tubes due to the communication hole defining means;
- and
- the predetermined adjacent two of the plurality of tube are adjacent to one another and are located within a longitudinal extent of the one of the plurality of fluid conduits of the header tank.
A heat exchanger for exchanging heat between internal fluid inside the heat exchanger and external fluid outside the heat exchanger, the heat exchanger comprising:
- a plurality of aligned tubes which are arranged one after another in an aligning direction;
- and
- at least one header tank unit, each of which includes:
- a plurality of fluid conduits which extend parallel to the aligning direction of the plurality of tubes and which are in communication with the plurality of tubes;
- and
- a communication hole defining means for defining a plurality of communication holes therethrough, wherein:
- each communication hole communicates between a corresponding one of the plurality of tubes and a corresponding one of the plurality of fluid conduits of the header tank unit such that each tube is spaced apart from the corresponding one of the plurality of fluid conduits;
- one of the plurality of fluid conduits of the header tank unit is directly in communication with at least one of at least two of the plurality of tubes through a corresponding one of the plurality of communication holes and is not in communication with at least another one of the at least two of the plurality of tubes due to the communication hole defining means;
- and
- the at least two of the plurality of tubes are located within a longitudinal extent of the one of the plurality of fluid conduits of the header tank.
A heat exchanger for exchanging heat between internal fluid inside the heat exchanger and external fluid outside the heat exchanger, the heat exchanger comprising:
- a plurality of aligned tubes;
- and
- at least one header tank unit, each of which includes:
- a plurality of fluid conduits in communication with the plurality of aligned tubes, wherein all of the plurality of fluid conduits are located within a width of each tube, which is measured in a direction perpendicular to an aligning direction of the plurality of aligned tubes;
- and
- a communication hole defining means for defining a plurality of communication holes therethrough, wherein each communication hole communicates between a corresponding one of the plurality of tubes and a corresponding one of the plurality of fluid conduits of the header tank unit such that each tube is spaced apart from the corresponding one of the plurality of fluid conduits.
