Patent ID: 7211891

Claim:
An electronic heat pump device, comprising: an emitter-side external electrode substrate; an emitter including a semiconductor substrate having one surface connected to the emitter-side external electrode substrate so as to allow conduction of electricity and heat, and an emitter electrode provided on the other surface of the semiconductor substrate; a collector-side external electrode substrate; a collector including a semiconductor substrate having one surface connected to the collector-side external electrode substrate so as to allow conduction of electricity and heat, and a collector electrode provided on the other surface of the semiconductor substrate; wherein the emitter and the collector are disposed such that the emitter electrode and the collector electrode face each other with a space therebetween, and wherein at least one spacer section which keeps the space between the emitter electrode and the collector electrode constant and which are electrically and thermally insulative is integrally formed in at least one of the semiconductor substrate of the emitter and the semiconductor substrate of the controller, and further comprising: a space retention member which is electrically and thermally insulative and disposed between the emitter-side external electrode substrate and the collector-side external electrode substrate for keeping a space between the emitter-side external electrode substrate and the collector-side external electrode substrate at a constant value; and a sealing member for maintaining vacuum between the emitter-side external electrode substrate and the collector-side external electrode substrate.
