St. No. 669173 is a known gas regulated heat pipe containing a sealed enclosure partially filled with heat carrier with evaporation, transport and condensation zones, and a non-condensable gas tank connected to the condensation zone, and the evaporation zone is in the form of a bellows, and a spring piston fitted in the tank, equipped with the opposite side of the spring with a rod connected to the end of the bellows 1.

Недостатком устройства вл етс невысокое быстродействие регулировани .The disadvantage of the device is the low speed control.

Цель изобретени - повышение быстродействи регулировани тепловой трубы.The purpose of the invention is to increase the speed of regulation of the heat pipe.

Поставленна цель достигаетс тем, что зона конденсации выполнена в виде сильфо . на, торец которого прикреплен к щтоку порщн , а соединение резфвуара с неконденсирующимс газом с зоной конденсации выполнено в виде гибкого эластичного шланга.The goal is achieved by the fact that the condensation zone is made in the form of sylphs. on, the end of which is attached to the ground shaft, and the connection of the rezvuar with non-condensable gas with the condensation zone is made in the form of a flexible elastic hose.

The condensation zone .4 is made in the form of a bellows 14, the end 15 of which is connected to a spring-loaded piston 12 located in a gas tank 6 by means of a rod 11. The evaporation zone 3 is located in the region of the heat source 16, and the condensation zone 4 is in the heat consumer region 17. The transport zone 5 is covered with thermal insulation 18 and is fixed motionless. On the inner surface of the housing 2 can be installed wick (not shown).

Claims

Gas regulated heat pipe works as follows. When heat is supplied from source 16 to evaporation zone 3, coolant 1 evaporates and its vapors move to condensation zone 4, where they condense and transfer their heat to consumer 17. Then condensate of coolant 1 returns to evaporation zone 3 and the cycle of operation of the heat pipe repeats . However, as the heat flux supplied to the evaporation zone 3 from the heat source 16 (for example, radiation) increases, the temperature and vapor pressure of the heat transfer medium 1 in the heat pipe increase. The vapor-gas interface is shifted in the direction of the gas tank 6. The increase in pressure of non-condensable gas 7 causes the piston 12 to move in the direction of the spring 13. The piston rod 14 of the piston 12 moves the end 10 of the bellows 9 and the end 15 of the bellows 14 to the side of the gas reservoir 6. bellows 9 almost completely leaves the area of the source of heat 16, and bellows 14, on the contrary, completely enters the area of the consumer of heat 17. Thus, when the heat flux increases, the gas regulation of the heat pipe operation occurs by reducing the heat consumption while increasing its efficiency to the consumer. In the operation of the heat pipe, the opposite variant is also possible when the heat flux reduced to the evaporation zone 3 from the heat source 16 decreases. At the same time, the temperature and vapor pressure of the coolant 1 in the heat pipe is reduced. In this case, the piston 12 under the action of the spring 13 goes down and part of the non-condensing gas 7 moves along the flexible plastic rail. Tang 8 from the reservoir 6 to the condensation zone 4, as a result of which the vapor-gas interface shifts towards the condensation zone 4. But since the ends 10 and 15 of the bellows 9 and 14 are attached to the piston rod 11 of the piston 12, and the heat pipe transport zone 5 is fixed, then when the rod 11 moves downward, the bellows 14 of the condensation zone 4 is compressed, and the bellows 9 of the evaporation zone 3 is stretched, which contributes to the withdrawal of the bellows 14 from the area of the consumer 17 of heat, and vice versa, its input into the region of the source of heat 16. Thus, when the heat flux decreases, gas regulation of the heat pipe operation occurs by increasing the heat consumption while reducing the heat release to the consumer. The proposed device improves the control speed by simultaneously changing the surface area of the evaporation zone and condensing the heat pipe.
