Abstract
A heat exchanging apparatus has a flow path with air tightness formed by joining a second sheet to a first sheet formed by bending the first sheet by stamping and fluid introduced into the flow path impinges on a wall of the flow path to perform heat exchange. A material constituting the flow path may be a metal sheet or an electrically-conductive plastic, and a small-sized and light-weight heat exchanging apparatus can be manufactured at a low cost.
Claims11
A heat exchanging apparatus, comprising:
- a first sheet formed with grooves by bending the first sheet by stamping;
- and
- a second sheet joined to the first sheet,
- wherein
- the grooves are provided with lateral grooves opened outward at a side face of the first sheet and elongated in one direction, and formed in another direction different from the one direction at predetermined intervals in a plural-stage fashion, and a plurality of longitudinal grooves connecting adjacent lateral grooves of the lateral grooves to each other such that the adjacent lateral grooves communicate with each other, the longitudinal grooves being perpendicular to the lateral grooves;
- a flow path is formed such that fluid introduced into one lateral groove of the lateral grooves positioned at on one end of the flow path flows to another lateral groove of the lateral grooves positioned at the other end of the flow path via the lateral grooves and the longitudinal grooves;
- and
- fluid caused to flow in the flow path impinges on a wall of the flow path perpendicularly to perform heat exchange and the fluid is caused to flow out of a fluid outlet port positioned at the other end of the flow path.
