Abstract
A heat transfer device with a plate sandwich structure includes at least two flow-duct-covering plates and one flow duct plate unit arranged in between which is formed of one or more superimposed flow duct plates each provided with flow duct breakthroughs. By means of the flow duct breakthroughs in one flow duct plate or by suitably overlapping flow duct breakthroughs of several adjoining flow duct plates, one or more flow paths are formed which extend predominantly in parallel to the plate plane between an inflow point and an outflow point. Such structures, capable of passing through one or more fluids passing through, are produced rather inexpensively and can be used, for example, as a battery cooling element.
Claims15
A heat transfer device, comprising:
- a sandwich structure constructed of several plates and/or plate sections arranged one above another, at least one of which is provided with flow-duct-forming breakthroughs, the sandwich structure comprising:
- at least two flow-duct-covering plates and/or plate sections and one flow duct plate unit arranged in-between which is formed of one or more superimposed flow duct plates and/or plate sections each provided with flow duct breakthroughs,
- wherein one or more distinct, separate flow paths, each of which extend continuously between an inflow point and an outflow point, are formed by the flow duct breakthroughs in one flow duct plate and/or plate section or by mutually overlapping flow duct breakthroughs of several adjoining flow duct plates and/or plate sections, said flow paths extending predominantly in parallel to the plate plane between the inflow point and the outflow point.
