Abstract
The utility model discloses a cooling dehumidifier for a wind driven generator. The cooling dehumidifier comprises a refrigerating system which mainly comprises a condenser, an evaporator, a throttling device, a dry filter, a compressor and other components; in addition, the cooling dehumidifier further comprises a dividing wall type heat exchanger, wherein the cold flow inlet and the cold flow outlet of the dividing wall type heat exchanger are connected between the evaporator and the compressor in series; the heat flow inlet and the heat flow outlet of the dividing wall type heat exchanger are connected between the condenser and the throttling device in series. The cooling dehumidifier has the advantages of low loss, energy conservation and the like.
Description
Technical field
The utility model relates to a kind of cooling and dehumidifying machine for wind-driven generator.
Background technology
Being arranged on the control panel of coastal or offshore wind generating and the corrosion that electric elements are easy to be subject to saliferous humid air, is mainly electrochemical corrosion, that is: the redox reaction of metal.Land and sea breeze can be the humid air containing salt, and periodically blows to intertidal zone and seashore every day, the humid air of saliferous (Na wherein
+and Na
+cl
-ion) can produce salt air corrosion to metal.
High humility has very large harm to the steady running of power electronic equipment, so dehumidifying becomes the basic demand of power electronic equipment.
The current high problem of cooling and dehumidifying machine ubiquity energy consumption, cooling and dehumidifying machine needs long-time continual work, so its energy consumption problem can not be ignored.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of cooling and dehumidifying machine for wind-driven generator, and it has the features such as loss is low, energy-conservation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: it comprises the refrigeration system being mainly comprised of parts such as condenser, evaporimeter, throttling arrangement, device for drying and filtering, compressors, it also comprises dividing wall type heat exchanger in addition, the cold flow gateway of dividing wall type heat exchanger is serially connected with between evaporimeter and compressor, and its hot-fluid gateway is serially connected with between condenser and throttling arrangement.
The utility model further improves and is: the hot-fluid gateway of dividing wall type heat exchanger is serially connected with between condenser and drier filter; Evaporimeter is a plurality of pipeline parallel-connection structures, at its cold-producing medium, flows between the evaporator pipeline of holding and is provided with magnetic valve; Evaporimeter is 3 pipeline parallel connections that length is identical; Magnetic valve is flowing between two pipelines of end near cold-producing medium.
The beneficial effect that adopts technique scheme to produce is: in the refrigeration system of dehumidifier, dividing wall type heat exchanger is set, its cold flow gateway is serially connected with between evaporimeter and compressor, its hot-fluid gateway is serially connected with between condenser and throttling arrangement, can spend again cold to condensed cold-producing medium, improve refrigerating capacity, thereby increase effect on moisture extraction; Also the suction temperature that has increased compressor, is conducive to compressor safe and stable operation simultaneously.Evaporimeter is a plurality of pipeline parallel-connection structures, at its cold-producing medium, flows between the evaporator pipeline of holding and is provided with magnetic valve; Hot operation environment, closed electromagnetic valve, cold operation environment, magnetic valve is opened, and rationally controls evaporimeter heat exchange area, therefore the utlity model has stable, the energy-conservation advantage of security of operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, condenser; 2, evaporimeter; 3, device for drying and filtering; 4, compressor; 5, dividing wall type heat exchanger; 6, pipeline; 7, magnetic valve.
The specific embodiment
Embodiment is as shown in Figure 1 known, it comprises the refrigeration system being mainly comprised of parts such as condenser 1, evaporimeter 2, throttling arrangement, device for drying and filtering 3, compressors 4, it also comprises dividing wall type heat exchanger 5 in addition, the cold flow gateway of dividing wall type heat exchanger 5 is serially connected with between evaporimeter 2 and compressor 4, and its hot-fluid gateway is serially connected with between condenser 1 and throttling arrangement; The hot-fluid gateway of dividing wall type heat exchanger 5 is serially connected with between condenser 1 and drier filter 3; Evaporimeter 2 is a plurality of pipeline 6 parallel-connection structures, at its cold-producing medium, flows between the evaporator pipeline 6 of holding and is provided with magnetic valve 7; Evaporimeter 2 is 3 pipeline 6 parallel connections that length is identical; Magnetic valve 7 is flowing between two pipelines 6 of end near cold-producing medium.
Energy-saving principle:
Dividing wall type heat exchanger in refrigeration system can be spent condensed cold-producing medium cold again, can improve refrigerating capacity, thereby increases effect on moisture extraction; Also the suction temperature that has increased compressor, is conducive to compressor safe and stable operation simultaneously.Evaporimeter is a plurality of pipeline parallel-connection structures, at its cold-producing medium, flows between the evaporator pipeline of holding and is provided with magnetic valve; Hot operation environment shut electromagnetic valve, thus be to reduce evaporating temperature in order to reduce disengagement area, control evaporating temperature within the loading range of compressor.Because the range of operation temperature span of dehumidifier is larger, if do not make disengagement area, do not change, can make compressor load excessive.Therefore the utlity model has stable, the energy-conservation advantage of security of operation.
