Heat removal equipment of refrigeration system for mine

Abstract

The invention discloses heat removal equipment of a refrigeration system for a mine, which comprises a casing of a heat exchanger, a heat exchange pipe component and a spraying component, wherein the heat exchange pipe component comprises flow dividing short pipes and heat exchange pipes of which the end parts are fixedly connected to the flow dividing short pipes, and both ends of the heat exchange pipes are respectively communicated with a liquid dividing pipe and a liquid collecting pipe by the flow dividing short pipes; and the spraying component comprises a first spraying pipe arranged on the radial section of the air inlet end of the casing of the heat exchanger. The heat exchange pipes of the heat removal equipment of the refrigeration system for the mine are connected with the liquid dividing pipe and the liquid collecting pipe by the flow dividing short pipes, so that flow dividing holes in the liquid dividing pipe and the liquid collecting pipe are greatly reduced, the structure is simple, and the manufacture is more convenient; meanwhile, the fluid pressure difference change in the length direction of the liquid dividing pipe and the flow distribution of a refrigeration medium of an air conditioning unit in each heat exchange pipe are uniform, the refrigeration medium can be fully in heat exchange with a spraying and cooling medium, the performance of heat removal is good, and the requirement of heat removal of an air conditioning unit system of a shaft can be met; and the water spraying pressure of the first spraying pipe can be regulated, the atomizing effect of spraying water can be ensured, and the performance of heat exchange of the heat exchange equipment can be further enhanced.

Description

Technical field [0001] The invention relates to a heat exchange device, in particular to a heat rejection device of a mine refrigeration system. Background technique [0002] The heat damage in the mine is becoming more and more serious. In the underground air conditioning unit system, the removal of the condenser heat is the key to the normal operation of the unit. Therefore, the heat exchanger of the mine air conditioning unit system is required to have good heat exchange performance. [0003] Traditional air conditioning units use tube-and-tube heat exchangers to remove heat. For tube-and-tube heat exchangers, the heat exchange tubes are usually straight and smooth, with a small heat exchange area and poor heat exchange performance. The heat exchanger covers a large area. [0004] Moreover, in the heat exchanger in the prior art, the heat exchange tube is directly connected to the liquid distribution tube, so the distribution holes on the liquid distribution tube are densely arra...

Problems solved by technology

[0003] Traditional air-conditioning units use tube-and-tube heat exchangers to discharge heat. For tube-and-tube heat exchangers, the heat exchange tubes are usually smooth straight tubes with small heat transfer area and poor heat transfer performance. The heat exchanger occupies a large area

[0004] And in the heat exchanger in the prior art, the heat exchange tube is directly connected to the liquid distribution pipe, so the distribution holes on the liquid distribution pipe are densely arranged, and the connection structure between the heat exchange tube and the liquid distribution pipe is complicated; and the dense arrangement of the distribution holes results in The fluid pressure difference at different parts on the liquid distribution pipe is relatively large, which also leads to the uneven distribution of the cooling medium in the heat exchanger of the air conditioning unit, so that the heat energy of the cooling medium cannot be fully absorbed by the cooling water, and the heat transfer efficiency of the heat exchanger is low.
