Abstract

The invention relates to heat engineering and m. used as technological equipment for the manufacture of heat pipes. The invention improves performance. The dosing tank (E) is filled in the form of a bellows 5, placed below the consumable E 1 and enclosed in cover A. The latter is connected to iO Jt 12 0 1-11 system 9 for displacing heat carrier (TH) from E 3, equipped with a control valve 10, having a gas discharge line to the atmosphere with a gearbox 11 installed on it and a safety valve (K) 12. Backbone 2 is installed in line 2 13. The light boiling ТН goes by gravity from Е 1 to metering Е 3, bellows 5 is stretched before contact with movement limiter 6 and filled with a metered count m TH. At the same time, with the help of the reducer I1 in the casing 4 a constant gas pressure is maintained, which is greater than the saturated vapor pressure TH, which prevents the boiling up of the TH in the bellows 5. With K10, the displacement system 9 is connected to the casing 4, compressed gas is supplied , the bellows 5 is compressed, and the dose of the TH is supplied to the heat pipe. 1 il.

Description

The invention relates to heat engineering, in particular to process equipment for the manufacture of heat pipes.

The purpose of the invention is to increase the productivity of the stand,

The drawing shows the scheme of the stand for filling the heat pipes with coolant.

The stand contains a supply tank 1 and a dosing tank 3 connected to it via a supply line 2 of the coolant, placed below the supply tank 1 and enclosed in a sealed casing 4. The dosing capacity 3 is made in the form of a sylphon 5 equipped with a movable movement stop 6 and a branch pipe 7 with shut-off valve 8 for connection to a heat pipe (not shown). System 9 is connected to the casing A to displace the coolant from the dosing tank 3, equipped with a control valve S, having a gas discharge line to the atmosphere with a gearbox 1 1 | installed on it and a safety valve 12. In line 2, a check valve 13 is installed. Flow tank 1 equipped with a heater 14 for controlling the temperature of the heat transfer medium, an electrical contact pressure gauge 15 and a safety valve 16.

The stand works as follows.

The light boiling heat carrier (for example, freon-P) flows by gravity from the supply tank 1 to the dosing tank 3, the bellows 5 is stretched

prior to contact with the limiter 6 and filled with a metered amount of coolant, while using the gearbox 11 in the casing 4 a constant gas pressure is maintained, greater than the saturated vapor pressure of the coolant, which prevents the coolant 5 from boiling up with the distributor valve 10 to the casing 4 system 9 displaces the coolant, connects the compressed gas at a constant pressure, the bellows 5 is compressed, and the dose of the coolant flows into the heat pipe. The stand can be automated.
