FIELD: engine manufacture. SUBSTANCE: electric heating device has body, heating plates, spring members, electrode, insulators of plates and electrode. Spring members are made from metal strip with width proportional to width of heating plates. Spring is fabricated from restoring members which number corresponds to number of plates. Restoring members are compressed by electrode placed between restoring members and connected to power supply wire. Restoring members may have restoring protrusions facing opposite members and arranged in regular order so that protrusion of one member corresponds to lack of protrusion on opposite member. EFFECT: increased efficiency of heat transfer from heating plates to body of heater and improved reliability of electric contact of plates with body. 1 cl, 4 dwg |
