Abstract

The invention relates to a condensation device. An anti-eddy supercooling condensation device comprises a condenser cylinder; the condenser cylinder is provided with an intake pipe and a liquid outlet pipe; a guide plate and an isolation plate are arranged in the condenser cylinder in sequence from top to bottom for dividing the condenser cylinder into an upper condensation area, a lower condensation area and a supercooling area, which are all provided with heat exchange pipes; the heat exchange pipe in the lower condensation area is shielded by the guide plate; a lower condenser inlet is formed between the edge of the guide plate and the wall of the condenser cylinder; the supercooling area is provided with a liquid inlet and a liquid outlet pipe; an intake pipe is arranged in the upper condensation area; and an anti-eddy separation plate is arranged on the liquid outlet pipe for dividing the liquid outlet pipe into two liquid outlet channels communicated with an outlet of the liquid outlet pipe. The anti-eddy supercooling condensation device has the advantages of low heat resistance of a lower-layer heat exchange pipe liquid film, high heat exchange coefficient, high liquid outlet supercooling degree and difficult generation of flash evaporation, and solves the problems of high heat resistance of a traditional condenser lower-layer heat exchange pipe liquid film, low heat exchange coefficient, low liquid outlet supercooling degree and generation of flash evaporation by liquid outlet eddies.

Description

technical field [0001] The invention relates to a condensing device, in particular to an anti-vortex supercooling condensing device. Background technique [0002] The condenser is an important piece of equipment in the refrigeration system. The performance of the condenser has an important impact on the power consumption of the compressor and the throttling cycle of the refrigerant. The performance of the condenser is reflected in the condensing pressure, subcooling degree and outlet flashing situation. The existing condenser has the disadvantages of large thermal resistance of the liquid film of the heat exchange tube in the lower layer, low heat transfer coefficient, small supercooling degree of the outlet liquid, and flash evaporation caused by the outlet liquid vortex. Contents of the invention [0003] The invention provides an anti-vortex supercooling condensing device with small heat resistance of the liquid film of the lower heat exchange tube, high heat transfer ...
