Abstract

The invention allows to increase the speed and simplify the design of the heat pipe during its operation in the quality of the temperature-displacement temperature transducer. The heat pipe contains a horizontal sealed case 1 with an evaporation zone 3 and a bellows 4 at the opposite end of the case. The bellows 4 is made with a fixed end wall in the form of a cup 5 eccentrically fixed, shifted up, with the cup 5 inserted in the bottom of the bellows 4. Case I is filled with coolant and non-condensable gas. When the pipe is operated, the heat carrier steam pushes the gas back into the cavity of the bellows .4 and, due to the small volume of the latter, there is a rapid increase in pressure and tension of the bellows 4 as the controlled organ moves. The eccentric placement of the snoophone 4 eliminates the need to install a wick inside it. 2, which simplifies the design of the heat pipe. 1 hp f-ly, 2 ill. §

The invention relates to heat engineering, namely to heat transfer devices.

The purpose of the invention is to increase the speed and simplify the design when the pipe is used as a temperature-displacement thermocouple. ;: In FIG. I schematically shows a heat pipe, longitudinal section; figure 2 - section aa in Fig, 1.

The heat pipe contains a horizontal sealed case I, partially filled with coolant and non-enclosing gas, with a wick 2 on its inner surface in zone 3 and evaporation bellows 4 with a fixed end wall made in the form of a cup 5; mounted on the case I | eccentric with an upward shift on

a pair) is increased, and the movable wall 6 of the skirt 4 begins to move. The speed of the pipe is due to the fact that the bellows 4 has a lighter volume and, therefore, the gas can be compressed faster with a small amount of steam. With an eccentric arrangement of the cup 5 relative to the housing j to return the condensate of the coolant to the evaporation zone 3, it is not necessary to provide the bellows with a wick 2, which simplifies the design of the pipe.
