DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model aims to provide a road surface snow and ice melting device with a unidirectional superconducting heat transfer element to solve the problems existing in the prior art. It can utilize the temperature difference between the surface and the underground to provide a heat source for the road surface, thereby achieving the purpose of self-melting snow and ice on the road surface, saving manpower and material resources, and avoiding pollution to the road surface environment.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1 As shown, this embodiment provides a unidirectional superconducting heat transfer element road surface snow and ice melting device, including a heat pipe shell 1, an air guide core tube 2 and a liquid guide core tube 3. The heat pipe shell 1 includes an evaporation section A and a condensation section C. The evaporation section A is used to be inserted into the ground, and the condensation section C is used to be buried in the road surface. The liquid guide core tube 3 and the air guide core tube 2 are both arranged in the heat pipe shell 1. The liquid guide core tube 3 extends downward to the lower part of the evaporation section A and is connected to the condensation section C upward. The upper end of the liquid guide core tube 3 is sealed and connected to the inner wall of the heat pipe shell 1 through an upper sealing partition 4. The liquid generated by condensation in the condensation section C is collected through the upper sealing partition 4 and guided to the evaporation section A through the liquid guide core tube 3. The air guide core tube 2 is downwardly connected to the upper part of the evaporation section A and upwardly passes through the upper sealing partition 4 to connect to the condensation section C. The air guide core tube 2 is used to guide the gas generated in the evaporation section A to the condensation section C.

[0024] The principle of unidirectional superconducting heat transfer is as follows: when the working medium encounters a ground temperature higher than the natural air, the liquid-to-gas heat transfer element starts working; when the natural air is higher than the underground temperature, the heat transfer element stops working; the working medium is at the bottom of the heat transfer element, the natural hot air is higher than the underground soil temperature, the medium cannot form a phase change, and the heat transfer element stops working.

[0025] When in use, the evaporation section A of the heat pipe shell 1 is inserted into the ground, and the evaporation section A absorbs underground heat energy. The liquid medium in the heat transfer element (heat pipe shell 1) evaporates into gas when encountering underground heat, and the gas is transferred to the condensation section C along the gas guide core tube 2. After the gas encounters the colder pipe wall in the condensation section C, the gas releases the latent heat of vaporization and condenses into liquid. Under the action of gravity, the gas flows into the liquid guide core tube 3 along the pipe wall and the upper sealing partition 4, and enters the evaporation section A through the liquid guide core tube 3 and evaporates again, and the heat source is provided to the road in a reciprocating cycle. The device can effectively prevent the condensation medium from flowing quickly to the evaporation section A through the liquid guide core tube 3, and release all the latent heat of vaporization in the condensation section C. The gas guide core tube 2 can introduce the gasified medium into the condensation section C. Through the arrangement of the liquid guide core tube 3 and the gas guide core tube 2, gas-liquid isolation can be formed in the tube cavity, reducing the heat loss of the gas during the transmission process and improving the efficiency of melting ice and snow. The device can fully utilize the temperature difference between the surface and underground to provide heat source for the road surface, realize the purpose of self-melting snow and ice on the road surface, save manpower and material resources, and avoid pollution to the road surface environment.

[0026] In this embodiment, the heat pipe shell 1 also includes an insulating section B, which connects the evaporation section A and the condensation section C. The heat pipe shell 1 is also sealed with a lower sealing partition 5, which is located below the upper sealing partition 4. The lower sealing partition 5 and the upper sealing partition 4 are vacuumed to form the insulating section B. The lower end of the liquid guide core tube 3 passes through the lower sealing partition 5 and extends to the lower part of the evaporation section A. The lower end of the gas guide core tube 2 passes through the lower sealing partition 5 and extends to the upper part of the evaporation section A. The insulating section B is closest to the road surface and is also the key part of the heat dissipation of the heat transfer element. The vacuum section is formed by vacuuming, which can effectively play a heat preservation effect, prevent the gas in the gas guide core tube 2 from releasing heat prematurely, effectively prevent the loss of heat energy during the conduction process, and improve the efficiency of snow and ice melting.

[0027] In this embodiment, the upper end of the air guide core tube 2 is arranged higher than the upper sealing baffle 4 to prevent the liquid from flowing back into the air guide core tube 2, and the lower end of the air guide core tube 2 is arranged flush with the lower sealing baffle 5, so that the gas can enter the air guide core tube 2 faster and improve the circulation efficiency. The upper end of the liquid guide core tube 3 is arranged flush with the upper sealing baffle 4, so that the condensed liquid can be collected by the upper sealing baffle 4 and completely enter the liquid guide core tube 3, avoiding the accumulation of liquid on the upper sealing baffle 4.

[0028] In this embodiment, one end of the condensation section C away from the insulation section B is sealed by a first end cover 6 .

[0029] In this embodiment, the heat pipe shell 1 is in an inverted L shape. The evaporation section A and the insulation section B are arranged in the vertical section of the inverted L-shaped heat pipe shell 1, and are arranged sequentially from bottom to top. The condensation section C is arranged in the horizontal section of the inverted L-shaped heat pipe shell 1, and the insulation section B and the condensation section C are connected by a rounded transition. In other embodiments, the heat pipe shell 1 can also be set to a T shape, the evaporation section A and the insulation section B are arranged in the vertical section of the T-shaped heat pipe shell 1, and are arranged sequentially from bottom to top, and the condensation section C is arranged in the horizontal section of the T-shaped heat pipe shell 1.

[0030] In this embodiment, one end of the evaporation section A away from the insulation section B is sealed by a second end cover 7 .

[0031] like Figure 2 As shown, the device is applied to a concrete or asphalt pavement structure, wherein the evaporation section A is inserted into the soil layer 8, the insulation section B is located in the cushion layer 9 and the cement gravel layer 10, and the condensation section C is buried in the concrete or asphalt pavement layer 11. When there is ice and snow on the concrete or asphalt pavement layer 11, the temperature of the soil layer 8 is higher than the surface temperature. At this time, the liquid working medium can form a phase change, and the liquid working medium absorbs the temperature of the soil layer 8 and evaporates into gas. The gas enters the condensation section C through the gas guide core tube 2 to release heat and condense into liquid. Under the action of gravity, it is collected along the tube wall through the upper sealing partition 4 and enters the liquid guide core tube 3, and then flows into the evaporation section A through the liquid guide core tube 3 and evaporates again. This cycle provides a heat source for the road and achieves the purpose of self-melting snow and ice on the road surface.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
