Description

(54) HEAT PIPE

Ubi contains an evaporation zone, divided by a partition into two chambers 1 and 2 n of the condensation ion zone 3. Chamber 1 communicates with condensation ac 3 o through the transport zone 4, and with Ka% tepoS 2 it connects channel 5 with a reverse coag. In accordance with the design shown in Fig. 6, pitch 3 is connected to chamber 2 with a path 7 having a similar check valve 8. 2, in chamber 1, limiter 9 is installed in the form of a pipe.

The pumping of condensate into the chamber 2 of the evaporation zone occurs under the action of the kinetic energy of the heat transfer fluid, which is in the gaseous state in chamber 1. The heat transfer fluid filled into chamber II, after heat supply, passes into the gaseous state and enters: zone 3, where it is condensed. The resulting gas pressure B: chamber 1 at this point closes the check valve 6, n the condensate through the line 7 enters the chamber. 2. Check valve 8 provides free passage of fluid in this direction. Thus, the heat transfer medium to the chamber 2 from chamber 1, the pressure in which decreases. Warm up smiling at 2, the coolant enters a gas-generating state. Under the action of the gas returning pressure, the valve 8 closes and the valve 6 opens, through which the coolant enters again | into the chamber 1. The circulation cycles repeat as long as there is a temperature difference in the evaporation and condensation voltages.

The location of the condensation zone 3 under the evaporating 11 {evaporates the discharge.

G i f

The transfer to the zone 3 of the coolant in the chamber 1 is in the liquid state, and the passage to this zone of only its gaseous part is ensured by the installation of the limiter 9 in the chamber 1.

The use of an increase in gas flow during its heating in a closed volume, as well as the use of partitions, connecting channels and reliable pressure valves for controlling its movement, allows to create heat pipes with a wide range of operating parameters ensuring high efficiency and reliability of operation.
