Abstract

The invention discloses a heat exchanger of a refrigeration dryer, and belongs to the technical field of refrigeration. The heat exchanger comprises a heat exchanger barrel, wherein two sealing platesare arranged in the heat exchanger barrel; a plurality of spiral rib heat exchange tubes are arranged between the sealing plates; a preheater baffle plate is arranged at the transverse position between the spiral rib heat exchange tubes; an evaporator barrel is arranged at the bottoms of the plurality of spiral rib heat exchange tubes; an air inlet and an air outlet are formed in the upper end ofthe heat exchanger barrel, the evaporator barrel is arranged at the bottom of the spiral rib heat exchange tubes, an evaporator is arranged in the evaporator barrel, and the preheater baffle plate guides air entering from the air inlet to the other end of the spiral rib heat exchange tubes. The heat exchanger is good in heat exchange effect, energy is saved, and compared with a traditional copperpipe heat exchange structure, the number of used pipes is small, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a heat exchanger for a cold dryer. Background technique [0002] The traditional cold dryer relies on the vapor compression refrigeration system to cool the compressed air, the water vapor in the compressed air is cooled and liquefied into condensed water, and the water is removed through the gas-liquid separator to obtain dry air. The cold dryer heat exchanger consists of two parts. Pre-cooler and evaporator, the compressed air first enters the pre-cooler to cool down, and at the same time, the compressed air at the outlet of the evaporator is heated up by the pre-cooler, and the compressed air enters the evaporator after being cooled by the pre-cooler, and the refrigerant in the evaporator tube is kept at about 0°C evaporating temperature, the compressed air is cooled to a saturated state of 2~10°C. The precooler is used to recover the cooling capacity of the evaporator...
