Description

Изобретение относитс к пайке и может быть использовано в приборостроении дл осуществлени пайки в труднодоступных и удаленных местах.The invention relates to soldering and can be used in instrument making for soldering in hard-to-reach and remote locations.

Известен электропа льник, содержащий корпус с нагревателем и па льный стержень 11.Known electric flax, comprising a housing with a heater and a solder rod 11.

Однако он не обеспечивает пайки в труднодоступных и удаленных местах, так как интенсивность нагрева в рабочей зоне ограничена теплопроводностью па льного стержн .However, it does not provide soldering in hard-to-reach and remote locations, since the intensity of heating in the working area is limited by the thermal conductivity of the solder rod.

Известен электропа льник, содержащий корпус с нагревателем и па льный стержень, выполненный в виде частично заполненной жидким теплоносителем герметичной трубки, образующей осевой канал дл транспортировки газообразной фазы теплоносител от нагреваемого конца трубки к охлаждаемому концу с рабочей кромкой 2|.Known electric flax, comprising a housing with a heater and a steam rod, made in the form of a sealed tube, partially filled with heat-transfer fluid, forming an axial channel for transporting the gaseous heat transfer phase from the heated end of the tube to the cooled end with working edge 2 |.

Но такой па льник не обеспечивает требуемой дальности теплопередачи стержней с болыиими тепловыми потоками.But such a pair does not provide the required range of heat transfer rods with large heat fluxes.

Цель изобретени - повыщение дальности теплопередачи.The purpose of the invention is to increase the range of heat transfer.

Указанна цель достигаетс тем, что электропа льник снабжен установленной в осевом канале с возможностью вращени перфорированной в зонах нагреваемого и охлаждаемого концов па льного стержн полой вставкой, на наружной поверхности которой выполнены шнековые лопасти, а на внутренней - образующие турбинное колесо лопатки аэродинамического профил .This goal is achieved by the fact that the electric rod is equipped with a hollow insert installed in the axial channel with rotation perforated in the zones of the heated and cooled ends of the pallet rod, on the outer surface of which the screw blades are made, and the blades of the aerodynamic profile forming the turbine wheel.

На чертеже показан общий вид электропа льника .The drawing shows a General view of the electric flax.

Claims

The electric flax comprises a housing 1 with a heater 2 and a steam rod 3 made in the form of a sealed tube 5 partially filled with heat-transfer fluid 4, forming an axial channel 6 for conveying the gaseous phase heat carrier 4 from the heated end 7 of the tube 5 to the cooled end 8 with the working edge 9. In order to increase the heat transfer range of the electrician, the flax is provided with rotatably mounted in the axial channel 6, for example, by means of conical sleeves 10 and 11 perforated in the zones of the heated and cooled end na ceiling elements rod 3 a hollow insert 12, on the outer surface of which are made schnekovye blade 13, and on the domestic |) ENPI forming a turbine blade I1 a: po; uina.vuicheskogo profile, respectively vzaimolsystnuyushie with liquid coolant 4 and its gaseous phase. To raise the torque of the turbine wheel in front of it, a blade 15, rigidly connected to the housing 1, can be installed. Electrope operates as follows. At the heated end 7 of the tube 5, the heat transfer fluid 4 boils into the gas phase, which through the perforations of the insert 12 and the axial passage 6 rushes at high speed to the cold end 8, where it condenses, transfers heat to the working edge 9 and passes into the liquid phase. In the axial channel 6, the gaseous phase, interacting with the blades 14, causes the insert 12 to rotate. At the cooled end of 8 ck (), the dessicating heat exchanger 4 through perforation holes 1e enters the annular cavity between insert 12 and tube 5 and is trapped with heated blades 13 1 and heated end 7 of tube 5, where it is again heated and turns into gas () b.php phase. G1rppudptelnaya circulating heat carrier increases the range of heat transfer. In this case, the transfer of large heat fluxes is possible, since the temperature increases; Tours of the gaseous phase of the coolant responsibly increase the speed of the apron of the insert 12. The turbine wheel formed by the blades 14 simultaneously performs the role of a mechanical nozzle, which increases the speed of transporting the gaseous phase of the heat sink through the axial channel 6 and intensifies the heat exchange. Claims of the Invention An electric flax comprising a body with a heater and a steam rod made in the form of a sealed tube partially filled with liquid heat carrier forming an axial channel for transporting the gaseous heat carrier phase from the heated end of the tube to a cooled end with a working edge, characterized in that increase of the heat transfer distance, it is equipped with a hollow rod mounted in the axial channel with the possibility of rotation perforated in the zones of the heated and cooled ends of the solder rod tavkoy, on the outer surface kotors) th performed auger blades, and c) the morning - forming a turbine blade airfoil.
