Description
Technical field
The utility model relates to refrigeration technology fields, and in particular to a kind of big temperature difference cooling system of oil inlet and outlet.
Background technique
The existing cooling scheme to cooled oil liquid: using air conditioner type refrigeration unit to oil liquid cool down there are the problem of such as
Under: 1. the oil inlet and outlet temperature difference is typically all at 5 DEG C or so.2. Refrigeration system matching evaporator is excessive, oil inlet and outlet temperature-difference
It can become larger, but refrigeration system fluctuation of service, will lead to compressor frosting and compressor low pressure.3. being unable to satisfy big flow oil liquid
Temperature control requirement.4. cooled medium changes in flow rate must not exceed 15%, refrigeration system fluctuation of service otherwise can be also resulted in.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, it is cold to provide a kind of big temperature difference of oil inlet and outlet
But system.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: big temperature difference cooling system of oil inlet and outlet,
Including compressor, condenser, evaporator, innovative point is: further including secondary heat exchanger and bucket, the compressor, condensation
Device and evaporator are connected by the way that pipeline is arranged, and form circulation, and the evaporator, bucket and secondary heat exchanger pass through setting
Pipeline and water pump are connected, and form circulation, the water pump is sent from extraction water in bucket to secondary heat exchanger, then is changed from secondary
The outlet of hot device is discharged into evaporator, and two independent airtight passages are arranged in the evaporator, one airtight passage is used for
The runner of water, and another airtight passage is used for the runner of refrigerant liquid, is similarly arranged two in the secondary heat exchanger
Independent airtight passage, one airtight passage is used for the runner of water, and another airtight passage is used for the runner of hot liquid.
Further, liquid storage device, filter and orifice union are set between the condenser and evaporator.
It further, further include condensation fan, the condensation fan carries out air-cooled against condenser.
After adopting the above structure, the utility model has the beneficial effect that
The utility model forms the water cyclic system of regime flow by setting water pump, secondary heat exchanger, evaporator, bucket
System, it is ensured that the cooled large range of variation of fluid flow does not influence the normal operation of refrigeration system；The suitable system of selection
(refrigerating capacity is greater than 50% or more calorific value, and secondary heat exchanger area is greater than common heat exchange area 100% for cooling system, secondary heat exchange
When), the control relatively to the relative constant outlet temperature of cooled medium may be implemented.

Water circulation system, it is ensured that the cooled large range of variation of fluid flow does not influence the normal operation of refrigeration system；It is logical
Additional suitable secondary heat exchanger 4 (preferably water oil plate heat exchanger) is crossed, the water temperature height and stream of refrigeration unit is adjusted
Amount variation is to guarantee that the temperature difference of oil liquid oil inlet and outlet reaches the expected requirement of operating condition.
In the present embodiment, liquid storage device 7, filter 8 and orifice union 9 are set, on the one hand between condenser 2 and evaporator 3
Refrigerant liquid flow can be controlled, on the other hand refrigerant liquid can be filtered, be conducive to later period use.
It further include condensation fan 10 in the present embodiment, condensation fan 10 carries out air-cooled, quickening condenser 2 against condenser 2
Refrigeration effect.
