Abstract
A heat exchanger comprising at least two substrates made of electro-caloric and/or pyroelectric material and stacked one on the other so as to form between the at least two substrates and at least one channel for a fluid; at least two electrodes at two opposed ends of the at least two substrates; a housing enclosing the stack of the at least two substrates and the at least two electrodes, and provided with at least one fluid connecting port; wherein the housing is made of a heat shrinkable flexible tube that is shrunk onto the stack of the at least two electrodes and forming the at least one fluid connecting port.
Claims11
A heat exchanger, said heat exchanger comprising:
- at least one substrate made of electro-caloric or pyroelectric material and forming at least one channel for a fluid;
- at least two electrodes at two opposed ends of the at least one substrate;
- a housing enclosing the at least one substrate and the at least two electrodes, and provided with at least one fluid connecting port;
- wherein the housing is made of a heat shrinkable flexible tube that is shrunk onto the at least one substrate and forming the at least one fluid connecting port;
- wherein the at least one substrate comprises at least two substrates stacked one on the other so as to form between the at least two substrates the at least one channel for a fluid;
- wherein the at least two substrates are spaced from each other by spacers arranged at the two opposed ends of the at least two substrates;
- wherein additional spacers are provided on two opposed faces of the stack of the at least two substrates so as to form with the heat shrinkable flexible tube two of the at least one channel for the fluid.
