Double-vibration heat pipe heat exchanger combination and ground source heat pump system thereof

Abstract

The invention provides a double-vibration heat pipe heat exchanger combination and a ground source heat pump system thereof. Speed sensing elements are arranged in the free ends of pipe bundles of a first heat pipe and a second heat pipe and used for detecting the flow speed of fluid in the free ends of the pipe bundles, the speed sensing elements are in data connection with a controller, the controller extracts speed data according to the time sequence, the number of the speed sensing elements is n, the differences Di=Vi-Qi-1 between the speed Vi in the current time period and the speed Qi-1 in the previous time period are sequentially calculated, arithmetic accumulation summation is conducted on the n speed differences Di, and when the value of Y is lower than a set threshold value, whether hot water heats the first heat exchanger and the second heat exchanger or not is controlled. Through speed difference change accumulation, the heat exchanger continuously vibrates to remove scale and exchange heat according to the temperature.

Description

technical field [0001] The invention belongs to the field of heat exchange, in particular to a utilization system of mine ground source heat pumps. Background technique [0002] Since the reform and opening up, my country's comprehensive national strength and people's living standards have been greatly improved. Among them, the gold industry has developed rapidly, people's demand for gold has continued to increase, and the mining depth has continued to increase. high demands. As the mining depth increases, the ground pressure and rock temperature increase, and the difficulties in improving drainage, support, ventilation and other conditions in mines also increase, and the technical difficulties faced will continue to increase. One of the most prominent problems in deep well mining is the deterioration of the underground thermal environment, which not only restricts the safe production and construction of mines, but also threatens the health of miners. [0003] The tradition...

Problems solved by technology

[0003] The traditional method to solve the problem of heat damage in deep mines is mine circulation ventilation, but there are many problems in this method

First of all, as the depth of the mine increases, the shortcomings of its cooling capacity and insufficient ventilation limit become more and more prominent, resulting in a gradual decrease in its cooling effect, making it difficult to meet actual needs

Secondly, the way of circulating ventilation in mines needs to consume a lot of electric energy to drive mechanical equipment to generate forced convection air, and the operation of mechanical equipment will inevitably generate noise, which is uneconomical and affects the working conditions of underground workers
