A pulsating heat exchanger and its deep well heat exchange system

Abstract

The invention provides a heat exchanger and a deep well heat exchange system thereof. The heat exchanger comprises a heat exchanger main body, a heat exchange tube, an inlet pipeline and an outlet pipeline; the heat exchange tube is arranged in the heat exchanger body, the inlet pipeline and the outlet pipeline are connected with the heat exchange tube, the heat exchange tube is characterized in that the heat exchange tube is an elastic tube bundle assembly, a bypass pipeline is arranged on the inlet pipeline, the pulse generation device is arranged on the bypass pipeline, the inlet pipeline and the bypass pipeline are respectively provided with main path valves and bypass valves, the pulsation flow needs to be generated and the size of the pulsating flow is determined through opening andclosing of the main path valves and the bypass valves. According to the heat exchanger and the deep well heat exchange system, the size of the opening degree of the bypass valves and the main path valves can be controlled, the pulsation flow and the size of the normal flow can be automatically adjusted, the heat exchange efficiency is improved, and the descaling effect is enhanced.

Description

Technical field [0001] The technical field of the heat exchanger of the present invention particularly relates to a thermal system for deep mine mining. Background technique [0002] In the process of deep mine mining, the deterioration of the underground thermal environment is very prominent. As the mining depth increases, the working face of the mine starts to be affected by high temperature after entering the deep part, which not only restricts the safe production and construction of the mine, but also threatens the health of the miners. my country's "Metal and Non-metallic Mine Safety Regulations" stipulate that the air temperature at the mining face of the production mine shall not exceed 26℃, and the air temperature in the electromechanical equipment chamber shall not exceed 30℃. When the air temperature at the above two working locations exceeds 30℃ and 34℃ The job must be stopped. At the same time, due to the needs of the process, the mining process will produce a large ...

AI Technical Summary

Problems solved by technology

Existing problems include: the effect of the ventilation system becomes worse with the increase of the working depth; the cost of workers’ cooling clothes is high, and the operation process is inconvenient; the underground refrigerator has difficulty in heat dissipation, and the use of air as the heat dissipation medium leads to poor cooling effect and high operating costs, etc. question

Fluid-induced vibration can cause severe noise and damage to the heat transfer tube bundle, and fouling on the surface of the heat transfer tube bundle can cause huge energy and resource losses
