Description

The invention relates to the field of heat engineering and can be used in thermal control systems of vehicles - automobiles, ships and aircraft.

The purpose of the invention is to stabilize the temperature on the surface of the condenser and to eliminate the precipitate of wet condensate. This goal is achieved in that in a heat pipe containing an evaporator with a wick, the circulation loop in the form of a closed loop from the condenser pipe, it is new that the condenser is made in the form of a single wire mesh, mounted in a transparent plate and connected to the body of the loop tion at individual points. In addition, the wires form a rectangular or diagonal grid.

As the analysis shows, no significant distinguishing features were found in the known analogues, therefore, the invention has significant differences.

The positive effect is that by stabilizing and maintaining the temperature on the surface of the condenser from the transparent plate, condensation from the moist air is eliminated and visibility is improved when driving vehicles, ships, automobiles, etc.

Figure 1 shows a heat pipe; figure 2 is a section aa in figure 1.

The heat pipe contains an evaporator 1 with a wick 2, a circulation loop in the form of a closed loop from a pipeline 3 and a capacitor 4. The condenser 4 is made in the form of thin (diameter d 100 μm) wires 5 and a transparent plate 6, for example, glass or plexiglass, wires 5 are connected outside the casing 7 of the circulation circuit and form at least one grid mounted, for example, in a glass plate 6 (windshield), which is additionally connected to the casing 7 of the circulation circuit using

cuffs 8. In addition, wires b form a rectangular or diagonal mesh, the nodes of which are connected by soldering or welding.

The heat pipe works as follows.

When heat is supplied to the evaporator 1, the coolant in the wick 2 evaporates, and the generated steam moves through the pipe 3 of the circulation circuit. In this case, due to heat removal to the environment by means of heat conduction and convection from the body 7 of the circulation loop through the wire 5 of the grid and plate 6, it is partially condensed. A two-phase flow consisting of liquid condensate and steam moves along the circulation loop in the form of a closed i loop in the direction of the evaporator. Cup 8 does not allow heat to pass through. The evaporative condensation cycle closes. This stabilizes the temperature over
