This invention relates to heat transfer devices.

A heat pipe is known that contains a housing with evaporation and condensation zones, in the latter of which a container with a getter that absorbs non-condensable gas is fixed to the end wall of the housing, during the operation of the pipe, as a result of chemical interaction of the heat transfer fluid with the construction materials of the pipe Cl J.

The disadvantages of this heat pipe are relatively low reliability due to the saturation of the getter and its output, and the low absorption efficiency of the gas at the end heat removal,

The closest to the technical essence of the present invention is a heat pipe containing a hermetic casing with an evaporation zone and a condensation zone located above it, in which a reservoir for noncondensing gas is located, combined with steam channel 2 J.

A disadvantage of the known heat pipe is the comparative complexity of the design associated with the need to make the tank in the form of a separate vessel fitted with a water seal, connected to the steam duct of the pipe.

The purpose of the invention is to simplify the design.

This goal is achieved by the fact that in a heat pipe containing a sealed enclosure with an evaporation zone and a condensation zone located above it, 40 in which a reservoir for ot- is located. non-condensable water, communicating with the steam channel, the condensation zone is made in the form of a horizontal plate with a system of channels that form 45: a tank for diverting non-condensing gas and communicating with the vapor channel at their ends.

The channels in the slab can be cylindrical and arranged in parallel, and the plate itself on the inner surface may have transverse grooves connected to the channels.

1 schematically shows a heat pipe, a longitudinal section; figure 2 - section aa in figure 1.

Heat pipe contains body 1

with an evaporation zone 2 and a condensation zone 3 arranged above it, made in the form of a horizontal plate 4 with a system of parallel cylindrical channels 5 inside it, extending at their ends into transverse grooves 6, made on the inner surface of the plate 4 at the side walls 7 of the housing 1 and open in the steam channel 8.

Heat pipe works as follows.

During the supply and removal of heat in the evaporation and condensation zones 2 through the pipe, heat and mass transfer is carried out with a change in the state of aggregation of the coolant. As a result of slow chemical reactions, the non-condensable gas is pushed aside by the heat carrier vapor into the grooves 6 and from there into the channels 5, where it remains during the subsequent operation of the pipe, having little effect on the effective thermal conductivity of the condensation zone 3.

Performing condensation in the form of a horizontal plate with a system of canals, forming a tank for diverting non-condensing gas and communicating with the vapor channel at its ends, simplifies the design of the heat pipe, since it does not require the tank to be made as a separate vessel and fixed inside the pipe body .
