Air cooling and heat pipe reinforced heat exchange highway pavement temperature reduction cooling device

Abstract

The invention relates to an air cooling and heat pipe reinforced heat exchange highway pavement temperature reduction cooling device, and belongs to the technical field of highway traffic safety. The cooling device comprises heat pipe condensation sections, heat pipe casings, heat pipe evaporation sections, heat pipe work media and welding components, wherein a single heat pipe consists of the heat pipe condensation section and the heat pipe evaporation section; the heat pipe casings are filled with the heat pipe work media; the heat pipe evaporation sections are arranged inside a highway pavement; the heat pipe condensation sections vertically stand at guard bars at two sides of a highway; the heat pipe work media include middle and low temperature media; the heat pipe evaporation sections arranged inside the highway pavement are laid in an inclined way. The cooling device has the advantages that environment air can be fully used as a natural cold source; the heat pipes are used for cooling the highway pavement from the inside; asphalt is enabled not to become soft in high-temperature season; the driving safety is improved; the conventional energy resources are not consumed; the heat exchange efficiency is high; the operation is stable; no movement components exist; the manual operation is not needed; the operation cost can be effectively reduced.

Description

technical field [0001] The invention relates to an air-cooled heat pipe enhanced heat exchange cooling device for highway road surface cooling, which belongs to the technical field of highway traffic safety. Background technique [0002] In summer, the highway pavement paved with black asphalt concrete has a strong ability to absorb solar heat radiation, and the pavement absorbs heat quickly and the temperature rises. Especially in the south, the temperature of highway pavement in high temperature season can be as high as 40~60℃. Asphalt becomes soft at high temperature, coupled with the effect of heavy driving, it will make the pavement structure unstable, greatly reduce the flatness, affect driving safety, and shorten the service life of the road. At present, there are no reports on cooling and cooling devices and technologies for highway pavement both at home and abroad. [0003] In the high temperature season, compared with the temperature of 40-60 ℃ on the highway roa...
