Title:
METHOD OF CONSTRUCTING A HEAT EXCHANGER OF AN INTEGRATED STEEL PIPE, AND HEAT PIPE USING UNDERGROUND HEAT
Document Type and Number:
WIPO Patent Application WO/2012/050292
Kind Code:
A1
Abstract:
The present invention relates to a method of constructing a heat exchanger of an integrated steel pipe, and a heat pipe using underground heat, and more particularly, to a construction method for burying a heat exchanger underground. In the construction method, the steel pipe and the heat pipe may be integrated with each other underground, in which an exploratory hole is formed because drilling technology and heat exchanger efficiency should be improved to reduce construction costs in technologies that are difficult to apply to general businesses due to the relatively high investment required for underground heat drilling. Also, a portion of the heat pipe may contact the outside to quickly cool or heat the heat pipe. Here, the heat exchanger and the fluid pipe may be buried underground to improve efficiency when compared to a technology in which a heat exchanger and a fluid pipe are exposed to the outside. Also, an outer surface of the steel pipe may be coated to prevent a surface contacting the outside from being corroded, and the fluid pipe may be maximally shortened in length to contact an upper end of the heat pipe, thereby improving efficiency. According to the method of constructing the heat exchanger of the integrated steel pipe and heat pipe using underground heat, 2-stage exploratory holes may be formed to separately drill exploratory holes having a large diameter and a small diameter, thereby reducing construction cost. Also, a portion of the heat pipe may be buried in a rock layer to directly receive underground heat. Also, the inside of the heat pipe may be filled with a thermal transfer material in a state where the inside of the heat pipe is maintained under a vacuum state to quickly receive underground heat. Also, the heat exchanger and a flow controller may be buried in a sand laying layer to prevent noise occurring from the heat exchanger and heat from being dissipated to the outside.
