A combination of double vibrating heat pipe heat exchangers and its ground source heat pump system

Abstract

The invention provides a combination of double vibrating heat pipe heat exchangers and its ground source heat pump system. The free ends of the first heat pipe and the second heat pipe are provided with speed sensing elements inside the free ends of the tube bundles to detect the flow velocity of the fluid in the free ends of the tube bundles. The speed sensing element is connected to the controller for data, and the controller extracts the speed data according to the time sequence. The number of the speed sensing elements is n, and the speed V of the current time period is calculated sequentially. i with the previous time speed Q i‑1 difference D i =V i -Q i‑1 , and for n speed differences D i Carry out arithmetic cumulative summation, when the value of Y is lower than the set threshold value, the controller determines whether the hot water heats the first heat exchanger and the second heat exchanger. The present invention makes the heat exchanger continuously vibrate and descale and heat exchange according to the temperature by accumulating the change of the speed difference.

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
