Description

fcfi

The invention relates to the field of heat engineering and can be used to supply or remove heat.

Known magnetic heat pipe containing a sealed filled with non-conductive heat carrier dispersed in its liquid phase magnetically susceptible particles housing with zones of evaporation and condensation, connected by a pipe passing through the condensation zone and made in the form of a perforated coil and placed outside the housing in in the condensation zone, a magnetic system that creates a magnetic field rotating around the pipe axis, made in the form of a three-phase stator of an electric motor equipped with a switch h.

A disadvantage of the known device is the complexity of its construction, due to the presence of a magnetic system in the form of a stator of a three-phase electric motor, as well as the need for the consumption of electric energy for its operation.

The purpose of the invention is to simplify the construction of a heat pipe.

The goal is achieved by the fact that in the condensation zone of the heat pipe are installed plate-type permanent magnets located with gaps between the opposite poles.

The drawing shows a device section.

The magnetic heat pipe contains a sealed housing 1 with an evaporation zone filled with coolant 2, which is a low-boiling liquid (alcohol, acetone, ether, etc.), and a condensation zone with lamellar permanent magnets 3 located in it, located with the gaps 4 between the opposite poles and installed so that their upper ends exit through the upper end wall of the housing 1, and rod spacers 5 are located between the lower ends so that the magnets 3 do not interconnect. The permanent magnets 3 are made of a CosSm alloy having a high magnetic energy of 1: 10 gs and are essentially super-magnetic.

The device operates as follows.

Liquids have the ability to magnetize, the passage between the poles of permanent magnets. This property is widely used in technology, for example, for magnetizing water, for treating a fuel-air mixture in a magnetic field in an internal combustion engine, and the like. The magnetization of aerosols and hydrosols is used to deposit (coagulate) them at the poles of electromagnets in magnetic filters. In this device, as a magnetic system for vapor deposition, permanent lamellar super-magnets 3 are used, located with gaps 4 between opposite poles. When heat is supplied to the evaporation zone, the coolant 2 boils and evaporates. The vapor particles rise up, filling the gap 4 between the poles of the supermagnets 3, magnetize and, being attracted to the poles of the magnets, coagulate on their surfaces, giving off their heat to the magnets, and when they merge with each other, they form a dropping liquid that flows into the base a heat pipe where it boils and evaporates again. Heat from the magnets 3 is removed by the protruding ends.

The proposed design accelerates vapor deposition, which intensifies the heat transfer process. This device may find application in heat supply systems, as well as in machine cooling systems.
