An electrostatic atomization device that prevents the cooling capability from being lowered due to contact of an atomization electrode with another ember, while effectively preventing surplus production of condensed water that would destabilize discharging at the distal end of the atomization electrode. the electrostatic atomization device includes an atomization electrode having a cylindrical electrode body and a base which is informed at a basal end of the electrode body and has a larger diameter than the electrode from the base to produce condensed water on the atomization electrode. Voltage is applied to the atomization electrode when the condensed water is produced to generate charged fine water droplets. A partition plate includes an insertion hole that receives the electrode body of the atomization electrode. The partition plate and the base of the atomization electrode form a water collection region in between.

Electrostatic atomization device

An electrostatically atomizing device includes different types of thermoelectric elements and an emitter electrode being configured to cause the electrostatically atomization. The emitter electrode is provided with a mounting member which the different types of thermoelectric elements are mounted on. The mounting member is provided with the electrical conductive path between the different types of thermoelectric elements.

Electrode

An electrostatically atomizing device capable of instantly giving an electrostatically atomizing effect without requiring a water tank. The electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, a water feeder configured to give water on the emitter electrode, and a high voltage source configured to apply a high voltage across said emitter electrode and said opposed electrode to electrostatically charge the water on the emitter electrode for spraying charged minute water particles from a discharge end of the emitter electrode. The water feeder is configured to condense the water on the emitter electrode from within the surrounding air, enabling to supply the water on the emitter electrode in a short time without relying upon an additional water tank. Thus, an atomization of the charged minute water particles can be obtained immediately upon use of the device.

Electrostatcially atomizing device

An electrostatically atomizing device includes an emitter electrode, an opposed electrode opposed to the emitter electrode, and a cooling means which condenses the water on the emitter electrode from within the surrounding air, and a high voltage source applying a high voltage across the emitter electrode and the opposed electrode to electrostatically charge the water for atomizing charged minute water particles from a discharge end of the emitter electrode. The device further includes a controller for discharging the charged minute water particles in a stable manner. The controller monitors a discharge current flowing between the two electrodes to control the cooling means for keeping the discharge current at a predetermined level, thereby regulating the atomizing amount of the charged minute particles from the emitter electrode.

A sintered body of a material for thermoelectric element having excellent thermoelectric performance and mechanical strength can be produced by the following method. A block of the material for thermoelectric element is provided. The block has an electric-current passing direction, in which electricity is supplied to obtain a desired thermoelectric performance of the thermoelectric element. The block is encased in an elongate capsule such that the electric-current passing direction of the block is substantially agreement with an axial direction of the capsule. After degassing the capsule, a forming operation for reducing a cross section perpendicular to the axial direction of the capsule is performed to obtain a formed capsule having a green compact of the block crushed by the forming operation therein. A heat treatment is then performed to sinter the green compact in the formed capsule. Finally, the resultant sintered body is removed from the formed capsule. This method is preferably used to manufacture a thermoelectric module that is a temperature control device using the Peltier effect.

Method of producing sintered body of material for thermoelectric element

A thermoelectric chip with exposed surfaces of N-type and P-type semiconductor elements on its top and bottom surfaces is prepared by arranging the semiconductor elements in a matrix manner such that each of the N-type semiconductor elements is disposed adjacent to the P-type semiconductor element through a space, and filling the space with a first resin material having electrical insulation. A metal layer is formed on each of the exposed surfaces of the semiconductor elements. Then, first electrodes are formed on the top surface according to a first circuit pattern. Similarly, second electrodes are formed on the bottom surface according to a second circuit pattern different from the first circuit pattern. An electrical insulation sheet of a second resin material containing a ceramic powder with high thermal conductivity is bonded to the top and bottom surfaces to obtain the thermoelectric module.
