Background technology
are along with the reach of science; The use of frequency converter also more and more widely; No matter be all can use frequency converter on the industrial equipment or on the household electrical appliance; To be the on-off action that utilizes power semiconductor device be transformed to the electric energy control device of required frequency with power frequency supply with frequency converter, can realize soft start or frequency control to AC induction motor.At present, the radiating mode of common frequency converter case generally has two kinds: a kind of is that radiator fan is positioned at radiator top, adopts the radiating mode of updraft; Another kind is that radiator fan is positioned at the radiator bottom, adopts the radiating mode to up-draught.The common ground of above-mentioned two kinds of radiating modes is it all is that heat is upwards shed, thereby plays the effect of protection power device.But in particular application, like the special-purpose control cabinet of electric hoist, in the time of need carrying out outdoor installation; Requirement to its degree of protection also can improve; And the radiating mode of aforesaid two kinds of frequency converter casees owing to offer ventilating opening at the frequency converter upper box part, is easy to receive the influence of external environment in the open under the environment; Reduce the degree of protection of frequency converter, have potential safety hazard in use.If do not offer ventilating opening at the frequency converter upper box part, can't effectively discharge heat again, thereby cause the power device on the radiator to cross cause thermal damage, make the frequency converter can't operate as normal.
Problem such as low and result of ventilating heat dissipation difference of degree of protection when being applied in the open air to common frequency converter case; Be necessary the structure of existing frequency converter case is improved; For this reason; The applicant has carried out good try, has found the way that solves the problems of the technologies described above, and the technical scheme that will introduce below produces under this background
Summary of the invention
The task of
the utility model is to provide a kind of degree of protection higher, and perfect heat-dissipating can effectively protect the power device on the frequency converter not receive cause thermal damage, prolongs the frequency converter frequency converter case in useful life.
The task of
the utility model is accomplished like this; A kind of frequency converter case; Comprise casing and be located at the converter plant in the casing; Described converter plant comprises radiator fan, radiator; Be characterized in: described casing offers on the side near radiator fan one side and is used for air inlet that outside air is communicated with the box house die cavity, and described casing is equipped with on bottom or the side side near the bottom and is used for extractor fan that the hot-air of box house die cavity is discharged to the external world.
in a specific embodiment of the utility model, described radiator fan adopts the radiating mode to canyon, and between air inlet, radiator fan, radiator and extractor fan, forms heat dissipation channel.
are in another specific embodiment of the utility model; Described converter plant comprises that also power device, mounting panel, first are installed a part and a part is propped up in second installation; Described power device is installed on the radiator, and described radiator is fixed on the mounting panel, and described radiator fan is positioned at the top of radiator and is installed in second to be installed on the part; Described second installs a part is fixed on the mounting panel, is fixed with first on the described mounting panel part is installed.
the utility model can effectively be protected the power device on the frequency converter in the frequency converter case because after adopting technique scheme, the beneficial effect that has: topology layout is reasonable, and the integral heat sink performance is good, prolongs the useful life of frequency converter.
