Abstract: The invention relates to medical technology, specifically to devices for local massage of the skin, especially facial skin. The purpose of the invention is to improve the effectiveness of the massage while making the device more ergonomic. The device comprises identical massaging heads (1, 2), each of which consists of the following: heating elements which are in contact with a thermal contact plate (8); a heat dissipation system (9) designed, for example, in the form of an air radiator; a housing (10) with a convex spherical surface (11) and a holder made up of the plates (12, 13) with an aperture (14) whose wall has a spherical concave surface, the aperture forming an articulated joint with the surface (11) and thereby ensuring close contact throughout the massage session between the thermal contact plate (8) and the area being massaged.

Abstract: A tubular thermoelectric module used primarily as a part of thermoelectric generators, comprising an inner thermal conductor with circular thermopiles embracing the inner thermal conductor, and with strips serving to interconnect the thermopiles; an outer thermal conductor in the form of several sealed taper clamps, each embracing a circular thermopile; and electric insulation units which insulate one thermopile from another and from the inner and outer thermal conductors.

Abstract: A thermoelectric generator comprising a thermoelectric module, means for burning fuel and supplying heat to the module, a cooling system including a hollow radiator filled with cooling liquid and a cooling jacket embracing the module and connected to the radiator by inlet and an outlet pipes, the jacket being inclined towards the inlet pipe, and the outlet pipe having at least one ascending portion, whereby a pressure differential is established that is required for the liquid circulation in the cooling system.
