Gravity type heat pipe and direct evaporation cooler compound evaporating and cooling water chilling unit

Abstract

The invention discloses a gravity type heat pipe and direct evaporation cooler compound evaporating and cooling water chilling unit which comprises a direct evaporation cooler, wherein the direct evaporation cooler consists of a filling, a water tank arranged on the lower part of the filling and a water spraying device arranged on the upper part of the filling; the water tank is connected with the sensible heat tail end outside the unit through a pipeline; the sensible heat tail end is connected with the water spraying device through a pipeline; the upper part of the water tank and the left side and the right side of the filling are provided with tubular heat exchange devices with the same structure respectively; air inlets are formed on the side walls, corresponding to the lower parts ofthe two tubular heat exchange devices, of a housing of the unit; and air outlets are formed on the side walls, corresponding to the upper parts of the two tubular heat exchange devices, of the housing of the unit. Due to the structure, the evaporating and cooling water chilling unit is optimized further, so the heat exchange efficiency for spray water and wet air is improved and self-made refrigerating effect is used fully.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to an evaporative cooling chiller combined with a gravity heat pipe and a direct evaporative cooler. Background technique [0002] At present, most of the structural forms of evaporative cooling high-temperature chillers are that the spray water is directly subjected to heat-humidity treatment in the packing section, and the low-temperature exhaust air is directly discharged into the atmosphere, which has not been rationally utilized. If the gravity heat pipe is used to recover the cooling capacity of the exhaust air of the current evaporative chiller, the condensing end of the heat pipe is used to dissipate heat; the evaporating end of the heat pipe pre-cools the outdoor air, so that the temperature of the air entering the direct evaporative cooler is lowered and then combined with The spray water performs heat and moisture exchange to enhanc...
