Specific embodiment：
In order to deepen to understanding of the present utility model, further is made to this utility model below in conjunction with embodiment and accompanying drawing
Describe in detail, the embodiment is only used for explaining this utility model, does not constitute the restriction to this utility model protection domain.
As shown in figure 1, this utility model includes cooling cycle system and water circulation system, cooling cycle system includes compression
Machine, the refrigerant gas of the High Temperature High Pressure Jing after compressor compression enter oil eliminator, refrigerant gas and the oil of High Temperature High Pressure
High temperature and high pressure gas of the mixture in oil eliminator after centrifugation, separation pass sequentially through constant pressure valve and cut-off non-return
Valve, constant pressure valve are mainly used in the internal pressure for controlling oil eliminator, it is ensured that the internal pressure >=1.0MPa of oil eliminator, it is therefore an objective to
In order that the lubricating oil in oil eliminator has enough pressure, make lubricating oil that compressor is smoothly supplied under differential pressure action, be pressure
The normal operation of contracting machine is provided and is ensured, after the effect of screw down nonreturn valve mainly prevents from shutting down, refrigerant gas are condensate in oil cooling
From device, Jing second pipes are condensed into highly pressurised liquid into water cooled condenser water cooled condenser, the liquid after being cooled, one
Dividing into board-like oil cooler and high-temperature hot oil carries out heat exchange.It is divided into Jing after stop valve from oil eliminator high-temperature hot oil out
Two-way：Oil temperature regulating valve B mouth is entered all the way, and another road is into board-like oil cooler and the cold-producing medium come from water cooled condenser
Liquid produces heat exchange, and the lubricating oil after the oily but device cooling of plate type is entered in oil temperature regulating valve C mouth, oil temperature regulating valve with warm
The valve element and control lifting spring of degree control, is accurately controlled the temperature of oil temperature regulating valve A mouth, so as to for compressor safety
Stable work provides sufficiently guarantee.
As shown in Fig. 2 the 6th pipelines of gas-liquid mixture Jing after heat-exchangers of the plate type enter along airflow direction
Two pipelines.Angularly A is needed during the 6th pipeline insertion second pipe（A<90）Carry out, be conducive to producing with the air-flow in second pipe
Raw siphonage, is ensured the cooling of oil.
As shown in figure 3, the refrigerant liquid come from water cooled condenser enters the horizontal pipe of board-like oil cooler, need
There is the gradient of the board-like oil cooler of slope aspect, it is ensured that make under liquid runs down slope current, it is impossible to produce liquid capsule, make pipeline increase resistance,
Affect cooling effect.
The 6th pipeline through the gas-liquid mixture after heat exchange is produced with high-temperature hot oil, the horizontal component of the 6th pipeline are needed
Want the oriented board-like oil cooled gradient.Because being gas-liquid mixture in the 6th pipeline after heat exchange, the 6th conduit slope
Will can allow generation airflow smooth entrance second pipe, can not equally produce liquid liquid capsule, make pipeline increase resistance, so as to affect
The cooling of oil.
Heat exchange, height heat exchange after are produced with cooling water into the high-temperature high-pressure refrigerant gas in water cooled condenser
