Description

Technical Field

[0001] The utility model belongs to the technical field of road and bridge engineering, and particularly relates to a combined installation structure of a road ice-melting and heat-equalizing heat pipe. Background Art

[0002] Snow and ice accumulation on roads in winter pose a serious threat to traffic flow, causing traffic jams at best and accidents at worst. Currently, the main methods for snow removal include traditional mechanical snow shoveling, snow melting agents, and road heating. Traditional mechanical snow shoveling is labor-intensive and inefficient, while snow melting agents can pollute the environment. Road heating is more expensive, but highly efficient and pollution-free.

[0003] Road heating for deicing and snow melting primarily involves direct electric heating, fluid pipe heating, and heat pipe heating. Compared to direct electric heating, fluid pipe heating, often used in conjunction with a heat pump, offers higher heating efficiency and can accommodate a wider range of heat sources. However, it typically requires the laying of a large number of thicker pipes, which can only be buried at greater depths. It is commonly used in cement concrete pavements or bridge decks. Heat pipes are man-made components with excellent heat transfer properties. They leverage the principles of heat conduction and the rapid heat transfer properties of phase change media to rapidly transfer heat from a heating object to the heat source. Their thermal conductivity exceeds that of any known metal. Gravity-based heat pipes are primarily used for deicing and snow melting. Gravity-based heat pipes consist of three components: a closed metal tube shell and tube body, with a small amount of working fluid and a capillary wick within the internal cavity. In terms of heat transfer, the heat pipe can be divided axially into an evaporation section and a condensation section. Depending on the application, an insulating section can be placed between the two sections. The basic working principle of a heat pipe is as follows: in the evaporation section of the heat pipe, the working fluid in the tube core evaporates due to heat, and takes away heat. This heat is the latent heat of evaporation of the working fluid. The steam flows from the central channel to the condensation section of the heat pipe, condenses into liquid, and releases latent heat at the same time. Under the action of the capillary structure, the liquid returns to the evaporation section, thus completing a closed cycle, thereby transferring a large amount of heat from the heating section to the condensation section.

[0004] The heat pipe condensation section is buried in the road surface or bridge deck structure to heat the road surface or bridge deck structure and then melt the snow on the road surface or bridge deck structure. Figure 1 As shown, the serpentine heat pipe condensation section 1 is buried in the road surface or bridge deck structure 3 along the direction of vehicle traffic. The serpentine heat pipe condensation section 1 has the advantage of a larger heating area, but has the disadvantages of a longer total length of the heat pipe condensation section 1 and high energy consumption. Figure 2As shown, a heat pipe condensation section 1 is buried in the road surface or bridge deck structure 3 along the vehicle's travel direction L. Two heat pipe condensation sections 1 are provided, spaced apart along the width of the road surface or bridge deck structure 3, with the spacing between the two sections roughly equal to the vehicle's wheelbase. Compared to heat pipe condensation sections with a serpentine structure, this heat pipe condensation section offers advantages such as energy savings and easier construction. Due to heat loss during heat exchange, the heat pipe condensation section 1 has a high-temperature end and a low-temperature end. In actual construction, the installation length of a single heat pipe condensation section 1 is greater than 60 meters. Due to the long length of a single heat pipe condensation section 1, the ice and snow melting efficiency of the heat pipe condensation section 1 gradually decreases from the high-temperature end to the low-temperature end. Specifically, the closer to the high-temperature end of the heat pipe condensation section 1, the better the ice and snow melting effect on the road surface or bridge deck structure; the closer to the low-temperature end of the heat pipe condensation section 1, the worse the ice and snow melting effect, or even no ice and snow melting effect at all.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a combined installation structure of a road ice-melting and heat-equalizing heat pipe, including a heat pipe condensation section, which is buried in the road surface or bridge deck structure along the vehicle travel direction L; two heat pipe condensation sections are provided, and the two heat pipe condensation sections are arranged at intervals along the width direction of the road surface or bridge deck structure; it also includes a sleeve, which is arranged outside the heat pipe condensation section; an equalizing heat transfer structure is provided between the heat pipe condensation section and the sleeve, and the contact area between the equalizing heat transfer structure and the sleeve gradually increases along the direction from the high-temperature end to the low-temperature end of the heat pipe condensation section.

[0007] Furthermore, the uniform temperature heat transfer structure is a grid structure clamped on the heat pipe condensation section, and the grid density of the uniform temperature heat transfer structure gradually increases along the direction from the high temperature end to the low temperature end of the heat pipe condensation section.

[0008] Furthermore, the uniform temperature heat transfer structure includes a heat transfer ring clamped on the heat pipe condensation section, and there are multiple heat transfer rings. The multiple heat transfer rings are arranged along the direction from the high temperature end to the low temperature end of the heat pipe condensation section, and the distance between two adjacent heat transfer rings gradually decreases.

[0009] Furthermore, the uniform temperature heat transfer structure is made of plastic.

It also offers advantages such as a simple structure and convenient construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is combined with Figure 3 、 4 5, and embodiments further illustrate the present invention.

[0019] The combined installation structure of the road ice-melting and heat-equalizing heat pipe includes a heat pipe condensation section 1, which is buried in the road surface or bridge deck structure 3 along the vehicle travel direction L; two heat pipe condensation sections 1 are provided, and the two heat pipe condensation sections 1 are arranged at intervals along the width direction of the road surface or bridge deck structure 3; it also includes a sleeve 2, which is sleeved on the outside of the heat pipe condensation section 1; a temperature-equalizing heat transfer structure 4 is provided between the heat pipe condensation section 1 and the sleeve 2, and the contact area between the temperature-equalizing heat transfer structure 4 and the sleeve 2 gradually increases along the direction from the high-temperature end 101 to the low-temperature end 102 of the heat pipe condensation section 1.

[0020] Both the heat pipe condensation section 1 and the casing 2 are in contact with a uniform temperature heat transfer structure 4. The casing 2 is mounted outside the heat pipe condensation section 1. The heat generated by the heat pipe condensation section 1 is transferred to the uniform temperature heat transfer structure 4, then to the casing 2 via the uniform temperature heat transfer structure 4, and finally to the road surface or bridge deck structure 3 via the casing 2. By providing the uniform temperature heat transfer structure 4 between the heat pipe condensation section 1 and the casing 2, the temperature transferred from the casing 2 to the road surface or bridge deck structure 3 is more uniform along the direction from the high-temperature end 101 to the low-temperature end 102 of the heat pipe condensation section 1. This ensures more uniform ice and snow melting efficiency for heat pipe condensation sections 1 buried over long distances, improving the effectiveness of such sections in melting ice and snow on road surfaces or bridge deck structures 3.

[0021] Along the direction from the high temperature end 101 to the low temperature end 102 of the heat pipe condensation section 1, the contact area between the uniform temperature heat transfer structure 4 and the sleeve 2 gradually increases. There are various specific implementation methods:

[0022] In the first embodiment, the uniform temperature heat transfer structure 4 is a grid-like structure clamped onto the heat pipe condensing section 1. The grid density of the uniform temperature heat transfer structure 4 gradually increases from the high-temperature end 101 to the low-temperature end 102 of the heat pipe condensing section 1. During installation, the grid-like uniform temperature heat transfer structure 4 is clamped onto the heat pipe condensing section 1, and the sleeve 2 is then placed over the uniform temperature heat transfer structure 4.

[0023] In a second embodiment, the uniform temperature heat transfer structure 4 includes a heat transfer ring mounted on the heat pipe condensation section 1. A plurality of heat transfer rings are provided, and the plurality of heat transfer rings are arranged along the direction from the high temperature end 101 to the low temperature end 102 of the heat pipe condensation section 1, with the spacing between adjacent heat transfer rings gradually decreasing. During installation, the heat transfer ring is mounted on the heat pipe condensation section 1, so that the plurality of heat transfer rings are arranged along the direction from the high temperature end 101 to the low temperature end 102 of the heat pipe condensation section 1, with the spacing between adjacent heat transfer rings gradually decreasing. The sleeve 2 is then mounted on the uniform temperature heat transfer structure 4 composed of the plurality of heat transfer rings.

[0024] Both of the above-mentioned embodiments can achieve a gradually increasing contact area between the uniform temperature heat transfer structure 4 and the sleeve 2 along the direction from the high-temperature end 101 to the low-temperature end 102 of the heat pipe condensation section 1. Consequently, the temperature transferred from the sleeve 2 to the road surface or bridge deck structure 3 is relatively uniform along the direction from the high-temperature end 101 to the low-temperature end 102 of the heat pipe condensation section 1.

[0025] Preferably, the uniform temperature heat transfer structure 4 is made of plastic.

[0026] Preferably, the sleeve 2 is made of steel.

[0027] The embodiments of this specific implementation are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
