Abstract

A pipe-buried geothermal heat exchanger belongs to the air-conditioner refrigerating technical field. The utility model is characterized in that a pipeline of the heat exchanger is made into a U-shaped or spiral structure, the outer wall of the pipeline is provided with a vertical fiber cooling plate and a lateral fiber cooling plate, and the pipe-buried geothermal heat exchanger makes full use of the difference in temperature between the upper and the lower parts of the earth surface, which effectively fulfills the purpose of heat exchanging. Meanwhile, the utility model has the advantages of simple and convenient production, low refrigerating cost, small occupied space and high heat conversion efficiency, etc.

Description

Buried tube type ground source heat interchanger

The utility model belongs to the air conditioner refrigerating technical field.

Traditional operation of air conditioning systems cold (heat) exchanged form.General employing wind or water are that medium carries out heat exchange, but owing to be subjected to environment and spacial influence, need to be equipped with auxiliary equipment or device, come supplemental heat source, and then have increased refrigeration (heat) cost.

The purpose of this utility model provides and a kind ofly can reduce refrigeration (heat) cost, energy savings, protection environment, improves the novel buried tube type ground source heat switch of refrigeration (heat) efficient.

The utility model is to realize like this, pipe laying pipeline 1 is " U " type structure, also can be processed into spirality or serpentine warp architecture, pipeline outer wall is provided with stud fin 2 or horizontal bar fin 3, and water inlet pipe 4 and outlet pipe 5 places near the ground are provided with inlet and outlet control valve door 6.

Adopt above-mentioned buried tube type ground source heat interchanger, made full use of face of land upper and lower temperature difference, effectively reached the purpose of heat exchange, this heat exchanger can horizontal or vertically be imbedded underground, can one group also can organize in parallel the use more.

Accompanying drawing is the manufacturing embodiment that the utility model is applied to central air-conditioning:

As shown in Figure 1: 1 is that pipeline, 2 is that stud fin, 3 is that horizontal bar fin, 4 is that water inlet pipe, 5 is that outlet pipe, 6 is valve.Pipeline 1 adopts seamless steel pipe or plastics, be bent into " U " shape structure,, also pipeline can be processed into spirality or serpentine structure according to the needs of heat exchange area, after adopting the steel plate cutting, vertical fin 2 and horizontal type fin 3 be welded on the pipeline outer wall, or the plastics one-shot forming.Water inlet pipe 4 and outlet pipe 5 near-earth places establish by-pass valve control 6.

Claims

1, a kind of buried tube type ground source heat interchanger, mainly form by pipeline 1, stud fin 2, horizontal bar fin 3, water inlet pipe 4, outlet pipe 5, valve 6, it is characterized in that pipeline 1 makes U " the shape structure; set up muscle fin 2 or horizontal bar fin 3 on the outer wall, water inlet pipe 4 and outlet pipe 5 near-earth places establish by-pass valve control 6.

2,, it is characterized in that pipeline 1 also can make spirality or " S " type warp architecture according to the needs of heat exchange area according to the described buried tube type ground source heat of claim 1 interchanger.
