Description
Technical field
The utility model relates to a kind of inverter with housing, and this housing comprises the first chamber and the second chamber being separated by partition wall.
Background technology
Inverter behaviour institute is known, and comprises for holding the housing of electric component and/or electronic component.Conventionally, this shells has extraneous air is drawn into the ventilation unit (being more specifically the ventilation unit of electric fan form) that comes cooling electric element or electronic component in housing.Because inverter is not only arranged in building, be also arranged on the outside of building, so electric fan not only by air intake in housing, also dirt, dust and moisture are drawn in housing.Therefore, the electric component in inverter case and/or electronic component will be dirty very soon.Such pollution may cause fault.The use that is arranged on the filter of electric fan upstream is also a problem, because obstruction can make cooling effect variation.
Utility model content
An aspect of the present utility model is to provide a kind of inverter, even under disadvantageous external condition, described inverter also has unrestricted improved cooling effect in the long time.According to the utility model, a kind of inverter is provided, this inverter has housing, this housing comprises the first chamber and the second chamber being separated by partition wall, it is characterized in that: described the first chamber is sealed as and blocks moisture and dirt, and the first chamber comprises and electric component and/or the electronic component of the cooling body thermal coupling being associated, the second chamber comprises described cooling body and dissipative cell, and cooling body and dissipative cell are arranged in the air-flow that the electric fan in the second chamber produces.
In addition, according to the utility model, the housing of inverter at least comprises the first chamber and the second chamber, and these two chambers are separated by wall portion that can installation elements on it.The first set of pieces (being preferably the element being associated with each cooling body) is positioned in a side of the first chamber mesospore portion, and the cooling body being associated is positioned on the opposite side of the second chamber mesospore portion.Such as other elements to be cooled such as transformer with high-protection level (IP grade), be also arranged in the second chamber, the second chamber comprises cooling unit, and is cooled because of the existence of cooling unit.Therefore, only accommodate cooling body and those to be cooled and chambers of inverter case of element with high-protection level by active cooling.Well-known, very insensitive to dirt and moisture as the cooling body of heat exchanger, especially more insensitive than electric component and/or electronic component.Therefore, cooling body and the element with high-protection level can be set directly in cool stream, wherein, and the pollution of cooling body and there is high-protection level (for example, the pollution of element IP65) only has slight influence to cooling effect.Certainly, also can be in the downstream such as cooling units such as electric fans or upstream corresponding filter is installed.
According to another aspect of the present utility model, for example, the second chamber can comprise ventilation slot, and it is relative with the cooling unit in the second chamber that ventilation slot is preferably arranged to, and makes cooling-air can run through the second chamber and flow to the other end from one end.
In addition, the first chamber can have the degree of protection higher than the second chamber, that is to say, the first chamber that contains electric component and/or electronic component can be sealed as dustproof and splash-proof, and the second chamber is easy to ventilation, therefore dustproof the and damp proof degree of the second chamber only need reach suitable degree.
Explain in more detail with reference to the accompanying drawings the utility model.
Accompanying drawing explanation
Fig. 1 is the perspective view according to inverter case of the present utility model.
Embodiment
In Fig. 1, inverter has the housing 10 with partition wall 60, and partition wall 60 is divided into the first chamber 70 of housing and the second chamber 80 of housing by housing.Partition wall 60 is received power consumption electric component and/or electronic component 50.Electric component and/or electronic component 50 itself extend in chamber 70, and the cooling body 40(being associated with electric component and/or electronic component 50 is, heat exchanger) be arranged in the opposition side of partition wall 60 and therefore extend to another chamber 80.This means that electric component and/or electronic component are thermally coupled to their cooling body by partition wall 60, thereby between electric component and/or electronic component 50 and the cooling body 40 being associated, there is thermal coupling, to allow heat to be passed to cooling body 40 from electric component and/or electronic component.Partition wall 60 can form the part in thermal coupling path, or alternatively, a part for a part for cooling body or electric component and/or electronic component 50 can extend through respectively the corresponding opening in partition wall 60, or a part for electric component and/or electronic component 50 can extend through the corresponding opening in partition wall 60.Under latter event, electric component and/or electronic component 50 can be directly installed on the opening on cooling body 40 and in sealed separation wall 60.
Such as other dissipative cells 55 such as transformer with high-protection level, also can be arranged in the second chamber 80, this is because high-protection level makes 55 pairs of pollutions of these elements insensitive.
The second chamber 80 comprises electric fan 20 and the corresponding ventilation slot 30 relative with electric fan 20 being arranged on housing 10.The first chamber 70 has than the higher degree of protection of the second chamber 80, to guarantee that electric component and/or electronic component 50 can not touch dirt and moisture.This is for example applicable to, except self having the electric component of high-protection level and/or electronic component (, the winding such as the casting mold such as transformer or choke, it is preferably arranged on or extends in the second chamber 80) all electric components and/or electronic component in addition.Other only has the electric component of low-power consumption or idle and/or any position that electronic component can be arranged on the first chamber 70, without being arranged on partition wall 60.Therefore, the first chamber 70 can be by active cooling, but effectively removes by the air-flow of the cooling body 40 that is associated and electric fan 20 heat that power consumption electric component and/or electronic component 50 produce.
