Abstract

A heat exchanging device has a main chamber, two sub-chambers, an inlet and an outlet. The sub-chambers extend outwardly from both planar walls of the main chamber. Disposed within main chamber and the sub-chambers is a medium directing insert. The insert has an angled surface on ends facing the inlet and the outlet, first directing the flow of the heat exchange medium into the main chamber, so that the heat exchange medium is dispersed within the main chamber, then directing the heat exchange medium out of the device through the outlet. The medium directing insert is bonded to the lateral walls of the sub-chambers to enhance the structural integrity of the device. The lateral walls of the medium directing insert cooperate with the planar and lateral walls of the main chamber to form channels for directing flow of the heat exchange medium within the device.

Dependent claims

A heat exchanger having a chamber assembly, the chamber assembly comprising:

a main chamber;
first and second sub-chambers;
and
a medium directing insert, wherein
the main chamber is formed by a lateral wall joined between spaced apart first and second planar walls,
the first sub-chamber is formed by a planar wall and a lateral wall which joins the planar wall of the first sub-chamber to the first planar wall of the main chamber, the planar wall of the first sub-chamber having an inlet formed therein,
the second sub-chamber is formed by a planar wall and a lateral wall which joins the planar wall of the second sub-chamber, the planar wall of the second sub-chamber having an outlet formed therein,
the medium directing insert has first and second lateral walls with first and second channels disposed therebetween, the first channel having a first angled surface facing the inlet and the second channel having a second angled surface facing the outlet, and
each of the first and second lateral walls on a first end of the medium directing insert has a contour to fit under and engage with the lateral wall of the first sub-chamber and on a second end of the medium directing insert has a contour to fit under and engage with the lateral wall of the second sub-chamber, at least one of the lateral walls of the medium directing member on the first end being bonded to the lateral wall of the first sub-chamber, and at least one of the lateral walls of the medium directing member on the second end being bonded to the lateral wall of the second sub-chamber.
