Multi-evaporation-section heat pipe coupling buried pipe system

Abstract

The invention provides a multi-evaporation-section heat pipe coupling buried pipe system which comprises a horizontal buried pipe and a multi-evaporation-section gravity type heat pipe and can providecontinuous and effective heat for a ground source heat pump system. The multi-evaporation-section gravity type heat pipe is buried in the lower portion of the horizontal buried pipe, multiple evaporation sections are distributed in soil in all directions in a radiation manner, the heat transfer rate from the soil to the horizontal buried pipe is increased through the efficient heat conduction capacity of the heat pipe, and the heat exchange amount between the soil and the horizontal buried pipe is effectively increased. The laying area of the buried pipe is reduced, and the system has the characteristics of low cost, high efficiency and the like.

Description

technical field [0001] The invention relates to a high-efficiency horizontal buried pipe system, which can be specifically applied to a ground source heat pump system. Background technique [0002] As a renewable energy source, soil source has the advantages of stable heat and large heat capacity. The ground source heat pump system can effectively use the heat in the soil and continuously provide heat for the building, which is an important development direction of building heating. [0003] The buried pipe system at this stage is mainly divided into vertical buried pipe system and horizontal buried pipe system. Vertical buried pipes have the disadvantages of difficult construction and high cost due to the need to drill wells in a vertical direction. Horizontal pipes are mainly laid in shallow soil. Although the construction difficulty and cost are reduced, they have the disadvantages of large footprint and fast heat supply decay. [0004] In order to enhance the heat tra...
