„(54) ТЕПЛОВАЯ ТРУБА„(54) HEAT PIPE

1one

Изобретение относитс к области теплотехники , в частности к тепловым трубам.The invention relates to the field of heat engineering, in particular to heat pipes.

Известны электрогидродинамические тепловые трубы, содержащие заземленный корпус с зонами испарени , транспорта и конденсации , и расположенный по оси корпуса высоковольтный электрод 1.Electrohydrodynamic heat pipes are known, which contain a grounded body with evaporation, transport and condensation zones, and a high-voltage electrode 1 located along the body axis.

Недостаток известных электрогидродинамических тепловых труб в необходимости использовани источника высокого напр жени .The lack of known electrohydrodynamic heat pipes in the need to use a high voltage source.

Цель насто щего изобретени - интенсификаци теплообмена путем создани разности потенциалов.The purpose of the present invention is to intensify heat exchange by creating a potential difference.

Это достигаетс тем, что труба дополнительно содержит теплообменник кип щего сло диэлектрических частиц с заземленным кожухом, в который введена зона конденсации , имеюща поперечные ребра, причем корпус заземлен только в зонах испарени и транспорта, отделенных от зоны конденсации посредством диэлектрической щайбы, а электрод Б зонах конденсации и транспорта снабжен электроизол цией.This is achieved by the fact that the tube additionally contains a fluidized bed heat exchanger of dielectric particles with a grounded casing, into which a condensation zone is inserted, having transverse ribs, and the housing is grounded only in evaporation and transport zones separated from the condensation zone by means of a dielectric plate condensation and transport is electrically insulated.

На чертеже схематично изображена оцисываема теплова труби.The drawing schematically depicts the heatable tube heatable.

Теплова труба содержит- зону 1 испарени , зону 2 транспорта и зону 3 конденсации , помещенную в кип щий слой диэлектрических частиц 4, размещенных в теплообменнике 5. Корпус тепловой трубы с капилл рно-пористой структурой снабжен ребрами 6 и установлен на диэлектрических щайбах 7. По оси тепловой трубы расположен высоковольтный электрод 8 с изол цией 9. Теплообменник кип щего сло имеет сетку 10 С размером чеек, .меньщим частиц дис10 персного материала. Труба частично заполнена диэлектрической жидкостью.The heat pipe contains an evaporation zone 1, a transport zone 2 and a condensation zone 3 placed in a fluidized bed of dielectric particles 4 placed in a heat exchanger 5. The heat pipe body with a capillary-porous structure is equipped with fins 6 and is installed on dielectric plates 7. A high-voltage electrode 8 with insulation 9 is located on the axis of the heat pipe. The fluidized bed heat exchanger has a 10 C grid with a cell size that minimizes particles of a dispersed material. The pipe is partially filled with dielectric fluid.

При трении диэлектрических частиц 4 о заземленный корпус теплообменника 5 и ребра 6 тепловой трубы зона конденсации зар жаетс статическим электричеством. При During the friction of dielectric particles 4, the grounded body of the heat exchanger 5 and the fins 6 of the heat pipe condensation zone is charged with static electricity. With

Claims

15 this zone 1 of evaporation and transport 2 is grounded. The electrode 8 has a metal contact with the condensation zone case and is isolated from the evaporator. The oppositely charged body of the condensation zone 3 and the electrostatic genus 8 are discharged through the dielectric working substance of the heat pipe by means of electroconvective movement of the latter to the evaporation zone and to the ground. Thus, elektricheskad ep,. where the energy source is the double fluidization of the fluidizing coolant gas, it closes. The proposed heat pipe design significantly increases the heat transfer coefficient from the cooling fins to the induced air flow, and the static voltage generated by the fluidized bed of dielectric particles is used to improve the heat transfer characteristics of the heat pipe. A thermal tube comprising a grounded housing with evaporation zones, a transport 8 and a condensation, and a high-voltage electrode located along the housing axis, characterized in that, in order to intensify heat exchange by creating a potential difference, the tube further comprises a heat exchanger of a boiling layer of dielectric particles with a grounded casing, into which a condensation zone is inserted, having transverse ribs, the casing being grounded only in evaporation and transport zones separated from the condensation zone by dielectric plate, and the electrode in the zones of condensation and transport is equipped with electrical insulation.
