Embodiment Construction

[0021] In conjunction with accompanying drawings 1 to 4, the present invention is further described:

[0022] A geothermal energy heat exchanger, comprising an inner tube 10 made of heat-insulating material and an outer tube 20 made of a heat-conducting material sheathed outside the inner tube 10, the tube cavity of the lower nozzle of the outer tube 20 is provided with a plug The head 30 and the plug 30 pass through the lumen from top to bottom and form a sealing fit with the inner wall of the lower nozzle of the outer tube 20. The inner tube 10 extends to the lower end of the lumen of the outer tube 20 and the two communicate with each other. The outer tube 20 The upper end is provided with a medium inlet, and the upper end of the inner tube 10 is provided with a medium outlet.

[0023] This heat exchanger abandons the existing heat exchange tube that only uses a single heat exchange tube as a collection device for geothermal energy, and uses the existing heat exchange tube,...

Abstract

The invention relates to a ground temperature energy heat exchanger and an installing method thereof. The heat exchanger comprises an inner pipe made of heat isolation materials, and an outer pipe arranged at the outer portion of the inner pipe in a sleeving manner and made of heat conduction materials. A plug is arranged at the lower end pipe opening position of the outer pipe, and closed structure fit is formed. The lower end of the inner pipe extends to the lower end of a pipe cavity of the outer pipe, and a communication structure is formed. A medium inlet is formed in the upper end of the outer pipe. A medium outlet is formed in the upper end of the inner pipe. Media are conveyed to the pipe bottom position through the outer pipe, the inner pipe communicating with the outer pipe is used for drawing the media to a ground source heat pump unit on the ground to be subjected to heat exchange, and ground temperature energy utilization is achieved. Through the outer pipe made of the heat conduction materials, the heat exchange efficiency between the outer pipe and the stratum can be improved. Through the inner pipe made of the heat isolation materials, the heat preservation effect on the media obtained after heat exchange can be ensured. The heat exchange efficiency of the heat exchanger is extremely high, and the number of ground source wells in a ground source heat pump air conditioner system can be reduced.

Description

technical field [0001] The invention relates to the technical field of geothermal energy application, in particular to a geothermal energy heat exchanger and an installation method thereof. Background technique [0002] As a huge, stable, controllable, clean and environmentally friendly energy, geothermal energy has been applied on a certain scale in some areas of my country at this stage. The development of geothermal energy is mainly through the ground source heat pump air conditioning system for heating and cooling. The principle of the ground source heat pump air conditioning system is to transport the medium to the ground for heat exchange, and extract the heat exchanged medium to the ground source on the ground. The heat pump unit and the ground source heat pump machine exchange heat with the indoor air-conditioning terminal system to realize cooling or heating of the building. [0003] In the existing ground source heat pump air-conditioning system, in order to obtai...
