The invention relates to refrigeration and cooling equipment, and can be used in the construction and reconstruction of cooling equipment refrigeration chambers for food.Known cooling device containing a grounded heat exchange elements in the form of pipes with high-voltage electrodes placed equidistant heat exchange elements. The edges of the heat exchange elements are made with perforation (SU 1698600 A1, F 25 D 21/04, 15.12.91). During operation of this device are formed filamentary is a, containing the generating electrode, heat-exchange elements and fans, and the screen generating electrode installed equidistant heat exchange elements (SU 1200091 A, F 25 D 13/00, 23.12.85).The disadvantage of these devices is that the air flow is not completely blows on the surface of the heat exchange elements and the working surface is only partially under the influence of electroconvective environment, so the heat transfer ability of the heat exchange elements is reduced.Closest to the present invention is a cooling device containing a grounded coil, booster air flow and generating electrode is located before the heat exchanger (SU 1219885 A, F 25 D 21/04, 23.03.86).The disadvantage of this cooling device is the fact that the generating electrode is located in front of the grounded electrode and vapor mixture passes through the section of heat exchange surfaces, and the fan is located at the exit of the air flow, which reduces the efficiency of the device due to the deposited liquid droplets on its surface.This invention is directed to the achievement of the technical result consists in increasing effective operation.This is due to the fact that the cooling device containing a grounded coil, booster air flow and generating electrode is located before the heat exchanger, characterized in that it has a system of grounded electrodes, the shape and dimensions of which correspond to the shape and size of the generating electrodes, while grounded and generating electrodes are interleaved one relative to another. The electrodes may be made rectangular or in the form of a cylinder mounted concentric.The invention is illustrated by drawings.In Fig. 1 depicts a cooling device that includes a housing 1, a grounded finned heat exchanger 2, the generating electrode or electrodes 3, which are located before the heat exchanger, the pump 4 air flow system grounded electrodes 5. Generating and grounded electrodes, respectively 3, 5 can be performed as mounted concentric cylinders (Fig. 2) or rectangular (Fig. 3).The cooling device operates as follows.The air flow sucked by the pump 4 air flow passes through the electrodes 3, 5 (generating and grounded) and the second camera, conductive cooling handling unpackaged food product (e.g. meat), deviate towards the grounded electrode 5, where it is partially condensed and solids (as in an electric field is icing at higher temperatures - 4-6oC higher than in the absence of an electric field). Particles of frost air flow are fond of pass through the heat exchange surface and into the cooling chamber where support high relative humidity, and the dry air passes through the heat exchanger 2, and thereby reduces inebration on heat transfer surfaces, thus increasing the continuity without defrost and reduce operational energy costs. The presence of systems of electrodes can save energy consumption by creating a working tensions between the electrodes and increases the safety during operation. 1.
