Description

Matrixing network duolateral PTC electric transducer

The utility model relates to a kind of heater members, particularly a kind of PTC electric transducer.

PTC is as novel exothermic material, since have heating rapidly, efficient is high, its resistance, Curie-point temperature can be selected by material prescription, electric current that passes through and device surface temperature can automatic controls, need not characteristics such as adjunct circuit just can keep stablizing, therefore be subjected to generally attention both domestic and external.Recently, PTC heater spare is from flat wing type, ripple type, the dull and stereotyped honeycomb type transducer of having developed into of single-piece.But preceding two kinds of transducers are because by wing type, the heat radiation of ripple type aluminum alloy sheet, so there is complex process, windage is big, and deficiencies such as thermo-lag are arranged.A kind of dull and stereotyped honeycomb type transducer in back, though its technology is simple, heater and radiator are integrated, its windage is big, has the contradiction between ventilation hole and the power, because the hole is too big or the thicker power that all will influence transducer of thickness improves.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of technology simple, and windage is little, high-power matrixing network duolateral PTC electric transducer.

Technical solution of the present utility model:

A kind of matrixing network duolateral PTC electric transducer, it is characterized in that it forms the integrated matrix body of duolateral (2) by the little rectangular opening piece (1) of a plurality of ptc materials, inwall is electrode (3) around the little rectangular opening piece of each of this matrix body (2) (1), the electrode (3) of each little rectangular opening piece (1) inwall, its front end face connects at horizontal and vertical interval, connect successively oblique, form the network electrode A, the electrode (3) of all the other each little rectangular opening piece (1) inwalls still connects with horizontal and vertical interval at the reverse side end face, oblique ways of connecting successively forms the network electrode B, and outer wall is provided with two external electrodes (4) (5) independently separately around the integrated matrix body of duolateral (2), wherein external electrode (4) is connected with its positive network electrode A, external electrode (5) is connected with the network electrode B of reverse side, constitutes electric transducer.

The utility model adopts the flat PTC of polylith to line up matrix, is combined into a plurality of square holes, the likeness in form honeycomb, and the every positive and negative two electrode crossings on different level networks of PTC connect, and link up into two organic whole electrodes, and its heating heat radiation unites two into one, and bulk deformation is little.The utility model removes has general PTC heater heating soon, the efficient height, outside the advantages such as electric current, the automatic control of temperature energy, it is little also to have windage, power is big, and technology is simple, and cost is low, characteristics such as flexible design are the desirable heating elements of fuel atomizers such as warm-air drier, hair dryer, air conditioner, vehicle heating device, automobile and motorcycle.
