More absorb heat；The workspace is uncapped and auxiliary blower including circuit board, control panel, wiring, the holding section of the circuit board
Divide and fitted with the heat sink, the auxiliary blower is located on housing, its air outlet is provided with dust-proof cushion, and the workspace is except auxiliary
It is to be fully sealed beyond the air outlet or the wiring for helping fan are uncapped when opening；The radiating area include radiator fan with
Heat emission hole, the radiator fan is fitted with the heat sink, and its air outlet is located at three different directions being connected with housing.
Further, the heat sink is provided with temperature sensor.
Further, the control panel is provided with a display screen, the real time temperature for showing the heat sink.
Further, the frequency converter is additionally provided with alarm, in the case where radiating plate temperature is too high, sends alarm signal
Number.
Further, the radiator fan is centrifugal fan, its axially vertical described heat sink.
Further, the auxiliary blower is tube-axial fan, its axially vertical described housing.
Further, the air outlet that the auxiliary blower is is downward.
Compared with prior art, the beneficial effects of the utility model are：Set heat sink that workspace is only with radiating area
It is vertical to separate, do not opening in the case that wiring uncaps, workspace is almost fully sealed, so as to prevent dust easily attachment or heap
Product is on the electronic component in frequency converter, then by circuit board clamping part of being fitted in heat sink side, and side sets radiation air
Fan, so as to avoid workspace from being almost fully sealed to cause the problem of frequency converter is overheated.

Embodiment
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, accompanying drawing is now compareed detailed
Illustrate embodiment of the present utility model.
Heat sink 2 is provided with a kind of frequency converter, including housing 1 and buckle 5, housing 1, the cut-off of housing 1 is divided into by heat sink 2
Workspace 3 and radiating area 4, workspace 3 separate completely with radiating area 4；Opened including circuit board 31, circuit board 32, wiring workspace 3
Lid 33 and auxiliary blower 34, including the clamping part of circuit board 31 are fitted with heat sink 2, and auxiliary blower 34 is located on housing 1, and it goes out
Air port is provided with dust-proof cushion 35, workspace 3 except air outlet and the wiring of auxiliary blower 34 uncap 33 opening when be fully sealed；Radiating
Area 4 includes radiator fan 41 and heat emission hole 42, and radiator fan 41 is fitted with heat sink 2, and its air outlet is located at what is be connected with housing 1
Three directions.Heat sink 2 is provided with temperature sensor, and control panel 32 is provided with a display screen, for showing the heat sink 4
Also there is alarm in real time temperature, frequency converter, in the case where the temperature of heat sink 2 is too high, send alarm signal.Housing 1 is in work
Make material that material that area 3 and radiating area 4 use used in radiating area 4 without, housing 1 relative to the material used in workspace 3
Matter is more absorbed heat；Radiator fan 41 is centrifugal fan, and its axially vertical described heat sink 2, auxiliary blower 34 is axial-flow type wind
Fan, its axially vertical described housing 1, the air outlet that auxiliary blower 34 is is downward.
The utility model embodiment, heat sink 2 independently separates workspace 3 and radiating area 4, is uncapped not opening wiring
In the case of 33, workspace 3 is almost fully sealed, because the clamping part of circuit board 31 is fitted with heat sink 2, circuit board 31 is exhausted
Most of heating is all transmitted on heat sink 2, and the opposite side of heat sink 2 sets radiator fan 41, and heat discharges rapidly frequency converter,
And the auxiliary of heat emission hole 42 excludes heat.By the real time temperature of temperature sensor senses heat sink 2, and it is communicated to display
On, it is easy to staff to observe, and when the temperature of heat sink 2 reaches to a certain degree, alarm signal is sent by alarm.Due to
The caloric value of circuit board 31 and it is not all be transmitted on heat sink 2, therefore, increase by one group of air outlet below workspace 3 downward
Auxiliary blower 34, further radiating.Because workspace 3 is almost fully sealed in the case of 33 not opening wiring and uncap,
So as to can also reach dust-proof purpose.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to
Above-mentioned embodiment, above-mentioned embodiment be only it is schematical, rather than restricted, this area it is general
Logical technical staff is not departing from the utility model objective and scope of the claimed protection feelings under enlightenment of the present utility model
Under condition, many forms can be also made, these are belonged within protection of the present utility model.
