Problems solved by technology

[0003] However, the problem of indirect utilization of geothermal energy in this way is that the inner wall surface area of ​​the outer pipe is limited, and the heat that it can obtain from the surrounding high-temperature rock formation and hot water and store in its pipe wall is limited, and the circulating medium is under gravity and pumping. Under the action of pressure

Abstract

The invention provides a heat exchanger which comprises an outer pipe arranged in a drill hole which is vertically downwardly drilled in the ground through a drilling machine and an inner pipe sleeved in the outer pipe. A low-temperature circulation medium enters a space between the outer pipe and the inner pipe through the entrance of the outer pipe to absorb heat from the outer pipe to turn into a high-temperature circulation medium to flow out through the inner pipe, and heat exchange circulation is formed; the outer wall of the inner pipe is provided with turbulent flow components capable of allowing turbulent flow to be produced from fluid between the inner pipe and the outer pipe.

Description

technical field [0001] The disclosure relates to a heat exchanger, in particular to a heat exchanger capable of enhancing heat exchange efficiency used in heat exchangers for mid-deep geothermal heat collection. Background technique [0002] Today, energy conservation and emission reduction are increasingly becoming the subject of environmental improvement, and geothermal energy, as a clean energy, has become more and more recognized by people. There are two ways to obtain these geothermal energy, one is to directly extract the groundwater containing geothermal energy, and the other is to indirectly obtain the geothermal energy in the groundwater, that is, to use the heat exchanger to transfer the groundwater in the middle and deep underground Geothermal heat is replaced and utilized. Obviously, the direct extraction of medium-deep groundwater is not sustainable, because it will lead to a certain degree of ground subsidence and land desertification due to the large-scale ex...
