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.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of big temperature difference cooling systems of oil inlet and outlet
System.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of big temperature difference cooling system of oil inlet and outlet, including
Compressor, condenser, evaporator, innovative point are: further include secondary heat exchanger and bucket, the compressor, condenser and
Evaporator is connected by the way that pipeline is arranged, and forms circulation, and the evaporator, bucket and secondary heat exchanger pass through setting pipeline
And water pump is connected, and forms circulation, the water pump is sent to secondary heat exchanger from extracting water in bucket, then from secondary heat exchanger
Outlet be discharged into evaporator, two independent airtight passages are set in the evaporator, one airtight passage is for water
Runner, and another airtight passage is used for the runner of refrigerant liquid, and two independences are similarly arranged in the secondary heat exchanger
Airtight passage, one airtight passage be used for water runner, and another airtight passage be used for hot liquid runner.
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 invention has the following beneficial effects:
The present invention forms the water circulation system of regime flow by setting water pump, secondary heat exchanger, evaporator, bucket, can
To guarantee the cooled large range of variation of fluid flow, the normal operation of refrigeration system is not influenced；The suitable refrigeration system of selection
System, secondary heat exchange (refrigerating capacity is greater than 50% or more calorific value, when secondary heat exchanger area is greater than common heat exchange area 100%),
The control relatively to the relative constant outlet temperature of cooled medium may be implemented.
