Abstract

The invention discloses a vertical buried pipe heat exchanger for preventing frost heave of roadbed, which comprises a heating mechanism, heat release components respectively connected to both ends of the heating mechanism, and connected to the lower end of the heating mechanism through a heat transfer pipe. The refrigeration heat exchange mechanism communicated with the heat release assembly; the heat release assembly includes a double-layer heat exchange tube assembly connected to both ends of the heat raising mechanism, a gas-liquid separator connected to the double-layer heat exchange tube assembly, and a gas-liquid separator connected to the gas-liquid separator. The branch pipe between the heat exchanger and the refrigeration heat exchange mechanism; the heat exchanger has a simple structure, and the whole is an assembled structure, which is convenient for transportation and construction needs, and has low production cost, reliable use, uniform heat dissipation, good heat exchange effect, and high heat exchange efficiency. high.

Description

technical field [0001] The invention relates to the technical field of ground source heat pump heat exchangers, in particular to a vertical buried tube heat exchanger for preventing frost heaving of roadbeds. Background technique [0002] In my country, permafrost reaches 2.15 million square kilometers, which has an important impact on the construction and later operation of railways or highways. In winter, because the density of water is higher than that of ice, in the frozen state, the frozen soil is like ice, and the volume expands during the condensation process, and the upper roadbed or steel rail is jacked up due to the expansion. In summer, the permafrost thaws and shrinks in size, and in winter, the raised roadbed or steel rails descend with the thawing of the permafrost. The repeated freezing and thawing of permafrost will cause serious deformation or damage to the subgrade, and even muddy and muddy discharge, and the rails will have wavy ups and downs, posing a th...
