Abstract

The invention relates to heat transferring devices with a refrigerating effect and allows increasing operational reliability and expanding the functionality of a pipe when using a mixture of components that absorb heat when mixed in liquid phases. The condensation zone 5 of the high boiling point component is connected by a capillary-porous condensate line (CS) 6, which has a mixing zone (ES) 7, and an evaporation zone (ZI) 3. The capillary-porous KII 8 condensation zone 4 of the low boiling component is connected to ES 7. When heat is supplied to ZI 3, both components of the mixture evaporate, and then first the high-boiling component and then the low-boiling component condense. The components in the liquid phases of KP 6 and 8 enter the ES 7, absorb heat, and follow ZI 3. 1 3.p. f-ly, 1 ill. i SL with 4 SO y 00 y

Description

FIELD OF THE INVENTION The invention relates to heat engineering, namely to heat transfer devices with a cooling effect.

The purpose of the invention is to improve operational reliability and enhance functionality.

The drawing schematically shows a heat pipe, a longitudinal section.

The pipe contains a capillary-porous structure 1 placed inside it, a refrigerating chamber 2, an evaporation zone 3 and a condensation zone 4 and 5, respectively, of low-highbinding components of the binary mixture filling the pipe, the latter zone being connected by a capillary-porous condensate cable 6, having an mixing zone 7 with an evaporation zone 3. The condensation zone 4 of the low-boiling component is connected by a second capillary-porous condensate line 8 to the mixing zone 7 in the first condensate line 6, the binary mixture is composed of components that absorb heat when mixed in liquid phases. Both condensate wires are enclosed in a common shell 9 and are separated in the transport zone 10 by a longitudinal partition 11, impermeable to the binary mixture, (heat flows are indicated by arrows).

Heat pipe works as follows.

When heat is applied in the evaporation zone 3, both components of the mixture evaporate, then the steam of the high boiling component (in zone 5), and then the low boiling (in zone 4), - first condenses. after which the components in the liquid phases

The condensate lines 6 and 8 receive 49 narn mixtures by a longitudinal partition.

in the mixing zone 7, heat is absorbed in the refrigerating chamber 2 and is followed in the evaporation zone 3. The loop closes. As components of a binary mixture, for example, propane and acetone can be used. The pipe can function in the absence of gravitational forces.
