Abstract

The utility model discloses a cooling device of a frequency converter, comprising an enclosed frequency converter cabinet (1) with a built-in frequency converter and an air cooling apparatus (2). Upper and lower ends of the frequency converter cabinet (1) are respectively provided with a hot air outlet (1.1) and a cold air inlet (1.2); the hot air outlet (1.1) is in an enclosed connection with an air inlet (2.1) of the air cooling apparatus (2) through a hot-blast main (3); and the cold air inlet (1.2) is in an enclosed connection with an air outlet (2.2) of the air cooling apparatus (2) through a cold air pipe (4). According to the utility model, the advantages of relatively low energy consumption and no waste of refrigerating capacity are possessed.

Description

The frequency converter cooling device
Technical field
The utility model relates to the frequency converter field, owing to relate to a kind of high-power high voltage frequency converter, specifically is meant a kind of cooling device of frequency converter.
Background technology
The requirement of the operating ambient temperature of high voltage converter is usually at 0 ℃~40 ℃, because frequency converter can distribute heat when operation, thereby causes the ambient temperature of operation of frequency converter too high and make the frequency converter overtemperature protection and trip easily.Particularly during the broiling summer because the higher heat that produces in the frequency converter self-operating process of adding of ambient temperature, through regular meeting overtemperature protection takes place and the thing that trips takes place, when serious even cisco unity malfunction, had a strong impact on normally carrying out of producing.
For addressing the above problem, existing solution generally is that frequency converter is placed in the air-conditioned room, utilizes air-conditioning to reduce the temperature of environment, thereby makes the ambient temperature of frequency converter operation reach requirement.But this mode owing to be that the entire environment temperature is lowered the temperature, must be used the air-conditioning of big refrigerating capacity if room space is big, energy consumption is bigger, and owing to is whole room to be lowered the temperature also caused the unnecessary waste of refrigerating capacity.
The utility model content
The technical problem that the utility model will solve is to the existing in prior technology weak point, and the frequency converter cooling device that a kind of energy consumption is lower, can not cause the refrigerating capacity waste is provided.
The technical solution of the utility model is; Following a kind of frequency converter cooling device is provided; Be provided with the airtight frequency converter cabinet of frequency converter in comprising, also comprise air cooling device, the two ends up and down of described frequency converter cabinet are respectively equipped with hot-blast outlet and cold wind import; Said hot-blast outlet is connected with the air inlet of air cooling device is airtight through warm-air pipe, and described cold wind import is connected with the air outlet of air cooling device is airtight through cool air hose.
After adopting above scheme; The utility model frequency converter cooling device places an airtight frequency converter cabinet class with frequency converter; Utilize then and form an airtight air cooling circulation canal between air cooling device and the frequency converter cabinet; The ambient temperature that need not outside the frequency converter cabinet is cooled off, thereby only needs less energy consumption can satisfy the needs to the frequency converter cooling, also can not cause the waste of refrigerating capacity simultaneously.
As preferably, described air cooling device includes blower fan and the surface cooler that is located at below the blower fan.
Adopt above-mentioned preferred version; Air cooling device utilizes blower fan and the surface cooler that is located at below the blower fan to become cold wind after the hot blast cooling processing in the air cooling device and feed and carry out heat exchange in the frequency converter cabinet getting into; So circulation; It is simple that the air cooling device of employing blower fan and surface cooler has mechanism, the advantage that good cooling results and energy consumption are lower.
Description of drawings
It in the accompanying drawing the utility model frequency converter cooling device overall structure sketch map.
Shown in the figure:
1, frequency converter cabinet, 1.1, hot-blast outlet, 1.2, cold wind import, 2, air cooling device, 2.1, air inlet, 2.2, air outlet, 3, warm-air pipe, 4, cool air hose.
Embodiment
For ease of explanation,, the frequency converter cooling device of utility model is elaborated below in conjunction with accompanying drawing:
Shown in accompanying drawing; A kind of frequency converter cooling device; Be provided with the airtight frequency converter cabinet 1 of frequency converter in comprising, also comprise air cooling device 2, the two ends up and down of described frequency converter cabinet 1 are respectively equipped with hot-blast outlet 1.1 and cold wind import 1.2; Said hot-blast outlet 1.1 is through air inlet 2.1 airtight are connected of warm-air pipe 3 with air cooling device 2, and described cold wind import 1.2 is through air outlet 2.2 airtight are connected of cool air hose 4 with air cooling device 2; Described air cooling device 2 includes blower fan and the surface cooler that is located at below the blower fan.
In the above-described embodiments; Preferred forms to the utility model is described; Obviously, under the inventive concept of the utility model, still can make a lot of variations; Also can adopt the mode of compressor cooling to realize mode like described air cooling device 2 to the frequency converter cabinet circularly cooling; It is outdoor to adopt this mode can hot-blast outlet directly be discharged hot blast, and the cold wind that refrigeration produces then directly enters frequency converter cabinet, also can adopt other air cooling device to realize independent refrigeration to frequency converter cabinet certainly.When the key of the utility model is frequency converter freezed frequency converter is placed in the airtight frequency converter cabinet, only need freeze to this rack when freezing then gets final product.At this, should explain that any change of under the inventive concept of the utility model, being made all will fall in the protection range of the utility model.

Claims (2)
