Heat pipe anchor rod air conditioner

Abstract

The invention discloses a heat pipe anchor rod air conditioning device which comprises an anchor rod, a supporting plate and a heat pipe. a threaded end is arranged at one end of the anchor rod, the end of the anchor rod with the threaded end is fixed on the supporting plate inward, the other end of the anchor rod is fixed on a surrounding rock, a cavity is arranged in the anchor rod, the heat pipe is installed in the cavity, the heat pipe comprises a rod body, a vacuum cavity and a liquid suction core, the net-shaped liquid suction core is installed on the inner wall of the rod body, and the vacuum cavity is arranged in the liquid suction core. The rod body is divided into an evaporation section, a thermal insulation section and a condensation section. Conductivity coefficient of the anchor rod is 80000W / (m-DEG C). The heat pipe anchor rod air conditioning device is simple in structure, has anchoring effect, and simultaneously has good heat-conducting property.

Description

technical field [0001] The invention belongs to the field of air temperature adjustment devices, in particular to mine or tunnel air temperature adjustment devices. Background technique [0002] The winter temperature in northern my country is extremely low (-10°C-30°C). In order to ensure a suitable working environment temperature in coal mines, the "Coal Mine Safety Regulations" stipulates that mines must be equipped with an air heating system, "to ensure that the air temperature below the air inlet is constant. Above 2C". At present, most mines use heating rooms to adjust the mine air temperature, such as figure 2 As shown, the cold air flow 10 is heated by the heating room to form a hot air flow 30 mixed with the cold air 20 to enter the downhole. The heating method in the heating room is mostly in the form of radiators, and the heat of these radiators comes from the boiler room burning coal, using electric heaters, etc. Due to the long winter in northern my country, t...

AI Technical Summary

Problems solved by technology

All the above technologies have shortcomings. 1. The mine air temperature adjustment method can only provide heat to solve the problem of low mine ambient temperature in winter. However, when the external ambient temperature of the mine is high in summer, the heating room cannot play a cooling role.

2. Water source heat pump technology cannot obtain more heat energy in mines with small water inflow

3. The air source heat pump mostly absorbs the heat energy in the return air of the mine, but in summer, the temperature difference between the outlet of the mine return air shaft and the ambient temperature outside the mine is small, so the effect of the air source heat pump is not obvious

4. When the above two heat pump technologies are used in mines, they can only concentrate the recovered energy to a certain place, and then transfer it to the heating room or other heat-using places on the ground. This process requires a relatively complicated heat transfer system. And it is difficult to transfer and utilize in the intricate tunnels underground
