Background technology
In order to give screw compressor sound insulation weakening, internal leakage sealing, the reduction delivery temperature in the screw type cold unit, must provide the lubricating oil of certain volume flow to screw compressor, so screw compressor must be equipped with a cover oil circulation system.In the process of refrigerator operation, lubricating oil absorbs the heat of compression and frictional heat and temperature raises.After oily temperature rise, oil viscosity reduces, and the internal leakage rate strengthens, and compressor performance reduces; The lubricating oil meeting carbonization of the too high back of oil temperature, even cause that compressor " latch " damages.Therefore lubricating oil must be through supercooling, and a kind of way of routine is that external oil cooler is set.Heat exchanger of this extra increase comes the method for cutting oil, and the unit cost is risen; On the other hand, make unit pipeline complexity, strengthen the unit floor space, make troubles to production, increase the risk of system leak simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of solution above-mentioned pipeline complexity, strengthens the unit floor space, makes troubles to production, increases the problems such as risk of system leak simultaneously, the condenser of the built-in oil cooler of problems such as reduction unit cost.
For solving the problems of the technologies described above, the condenser of the utility model built-in oil cooler comprises: shell and tube condenser and the water inlet and the delivery port that are arranged on described shell and tube condenser one end; Refrigerant inlet and refrigerant outlet, described refrigerant inlet and described refrigerant outlet are separately positioned on the cylindrical shell of described shell and tube condenser; Also be provided with lubricating oil pipeline in described shell and tube condenser, be provided with lubricating oil inlet and lubricating oil outlet at the two ends of described lubricating oil pipeline, described lubricating oil inlet and described lubricating oil outlet stretch out outside the described shell and tube condenser.
Preferably, also be provided with a sagging plate at described shell and tube condenser.Described refrigerant inlet and described refrigerant outlet are separately positioned on the different cylindrical shells of described shell and tube condenser with described lubricating oil inlet and described lubricating oil outlet.
Preferably, further be provided with refrigerant line at described lubricating oil pipeline, described refrigerant line one end is communicated with the cavity of described shell and tube condenser, and an other end of described refrigerant line is communicated with described refrigerant outlet.
The integrated oil cooler of the condenser of the utility model built-in oil cooler makes the unit pipeline simple in one, and convenient production reduced the unit floor space, reduces the unit slip.And the condenser of the utility model built-in oil cooler is cheap, and compact conformation is particularly useful for the freezing unit of screw type low-temperature and screw ice making unit.
