Abstract

The invention discloses an asphalt pavement cooling device, which comprises two main parts, i.e. an evaporation pipe section and a condensation pipe section. The condensation pipe section includes a condensation pipe outer pipe and a condensation pipe inner pipe, and the evaporation pipe section includes an evaporation pipe main pipe and evaporation pipe branch pipes. When the pavement temperature is higher than the air temperature, a working medium filling the device undergoes gas-liquid circulation spontaneously so as to dissipate the pavement heat into the air and reduce asphalt pavement rutting, flushing, translation and other diseases caused by temperature rise. Single condensation pipe is connected to a plurality of evaporation pipes, the cooling area of single condensation pipe is increased, and the cooling efficiency is greatly improved. Also, the condensation pipe can be combined with street lamps, advertising boards and other road affiliated facilities into a whole, thus having no influence to the appearance.

Description

technical field [0001] The invention relates to the field of cooling devices, in particular to an asphalt pavement cooling device. Background technique [0002] The hot rod is a heat conduction system in which vapor and liquid flow in opposite directions. It is a sealed tube filled with a certain amount of working fluid (such as nitrogen, propane, carbon dioxide, etc.), the upper end is a condenser with cooling fins, the lower end is an evaporator with working fluid, and the middle is an adiabatic section. When the temperature of the condenser is lower than the temperature of the evaporator, the liquid working medium in the evaporator absorbs heat and evaporates. Under the action of the pressure difference, the steam rises to the end of the condenser, releases the latent heat of vaporization, and dissipates heat through the heat sink. The steam The working fluid is also cooled and condensed into liquid beads. Under the action of gravity, the liquid beads flow back to the ev...
