Heat exchanging device and condenser with built-in oil separation system of heat exchanging device

Abstract

The invention discloses a condenser with a built-in oil separation system. The oil separation system is arranged in the condenser and has the advantages of being high in oil separation efficiency, simple in structure, simple in pipeline and the like. The oil separating system first carries out primary separation through a knocking oil separation shell, then carries out secondary separation through a flow equalization board, and finally caries out tertiary separation through a filter screen. The oil separation efficiency is improved through the arrangement, coolants can evenly enter the condenser and make contact with a condenser pipe more evenly through design of an outlet of the oil separation system, and the heat exchanging efficiency of the condenser is improved. The invention further discloses a heat exchanging device with the condenser with the built-in oil separation system.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a heat exchange equipment and a condenser with a built-in oil separation system. Background technique [0002] Since the screw refrigeration compressor sprays a large amount of lubricating oil, the mixture of refrigerant vapor and oil is discharged from the compressor exhaust port. Since the lubricating oil does not evaporate, an oil film will be formed on the wall of the heat exchanger, so that The heat transfer effect and cooling efficiency are greatly reduced. The solution is to add an oil separator before the mixed gas enters the refrigeration system to separate the lubricating oil. At present, most units use the oil separator as a separate container, which is placed in front of the condenser, so that the lubricating oil is separated before entering the refrigeration system, but this structure has the disadvantages of high production cost, large space occupat...

Problems solved by technology

At present, most units use the oil separator as a separate container, which is placed in front of the condenser, so that the lubricating oil is separated before entering the refrigeration system, but this structure has the disadvantages of high production cost, large space occupation, and complicated pipelines.

[0003] In order to overcome the above shortcomings of the external oil separator, the structure of the built-in oil separator is proposed. There are currently two types of built-in oil separators, one is the oil separator built in the compressor, but the oil separator built in the compressor has a complicated structure and installation Difficulties and other shortcomings, so an oil separator built into the condenser was proposed. This structure Chinese patent has also published several patents. The structures are basically similar, and they all add a bow-shaped shell on the condenser. Oil separator, but the oil separation efficiency is not very high, and the speed of the refrigerant entering the condenser is not uniform, resulting in a low heat transfer rate of the condenser
