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;
- and
- at least one header tank unit, each of which includes:
- a plurality of fluid conduits communicated 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.
A manufacturing method of a heat exchanger comprising:
- forming a plurality of communication holes through an intermediate plate;
- assembling a header tank unit, which includes the intermediate plate;
- installing a plurality of tubes to the header tank unit;
- and
- joining the tubes to the header tank unit by soldering.
