Problems solved by technology

The currently used air cooler adopts a disc tube structure. Due to the large dust content in the underground air, the outer surface of the heat exchange pipe is easy to accumulate dust, resulting in low heat exchange efficiency, and the dust in the pipe is difficult to clean.
In addition, the air cooler is bulky and heavy, which is not convenient for transportation, installation and maintenance.

Abstract

The invention relates to a novel mining air cooler, which is used for cooling and dehumidifying ventilation air of a mining working face of a mine, and comprises a case, the case is internally provided with a cavity, and the case is provided with an air inlet, an air outlet, a water inlet pipe and a water outlet pipe, the air inlet and the air outlet are communicated with the cavity, and the water inlet pipe and the water outlet pipe are communicated with the cavity; the air duct fins are arranged in the cavity, the air duct fins are communicated with the air inlet and the air outlet respectively to form an air inlet channel, and the air inlet channel is communicated with the air outlet of the fan; the water channel fins are arranged in the cavity, and the water channel fins are communicated with the water inlet pipe and the water outlet pipe respectively to form a water inlet channel; wherein in the cavity, the air channel fins and the water channel fins are alternately arranged in a layered mode, and partition plates are arranged between the air channel fins and the water channel fins. The underground heat exchanger is suitable for severe underground environments and has the advantages of high heat exchange efficiency, small ventilation resistance, small size, light weight and convenience in transportation, installation and maintenance.

Description

Technical field [0001] The present invention relates to the field of air cooler technology, in particular refers to a new type of mining air cooler. Background [0002] In order to improve the working environment in the mine, improve labor efficiency and safety benefits, the mine has set up a mechanical refrigeration cooling system to achieve the goal of improving the working environment of the mining face. Mine air cooler is the end heat exchange equipment in the mine cooling system, the mine cooling system prepares frozen water, through the insulation pipeline is transported to the mining air cooler arranged on the mining work surface, the air entering the mining work surface is cooled and dehumidified. The air cooler currently used adopts a disc tubular structure, due to the large dust content in the downhole air, the outer surface of the heat exchange pipe is easy to dust, resulting in low heat exchange efficiency, and the pipe dust is not easy to clean. In addition, the ai...
