Abstract
The utility model discloses a frequency converter, comprising a lower casing, a transformer, a fan, a radiator which is fixed on the lower casing, a power module which is fixed on the radiator, a power board which is fixedly connected on the power module and a capacitance board which is welded with an electrochemical capacitor. The capacitance board and the power board are fixedly connected, and are mutually plumbed. The capacitance board is fixed on the lower casing of the frequency converter. The power board and the capacitance board are formed a reverse L-shaped grafting structure along the radiator, which makes full use of the inner space of the frequency converter. The radiation effect is great, and the environment temperature of the capacitance is reasonable.
Description
Technical field
The utility model relates to a kind of frequency converter, specifically, relates to the frequency converter of realizing miniaturization, good heat dissipation effect by the interior spatial structure collocation.
Background technology
Along with China's science and technology development, converter technology is increasingly mature, and wherein one of most important development trend is exactly the miniaturization development.Traditional frequency conversion device capacitor board many with the parallel placement of other circuit boards, but when the power amplifier board width is bigger than radiator width, can not make full use of the space, seriously hindered the miniaturization of frequency converter.Thereby the frequency converter that has adopts the radiator die sinking, reserves the space of placing electric capacity in radiator, in the hope of solving the problem of miniaturization.But the problem of thereupon bringing is: the radiator cost increases, and electric capacity is surrounded by radiator, thereby the ambient temperature increase causes the electric capacity lost of life.The improvement of power device heating and the development of cooling technology also become the major reason of miniaturization.
Summary of the invention
The purpose of this utility model is, a kind of frequency converter is provided, to overcome existing frequency converter further miniaturization and the too high technical problem of capacitive environment temperature.
In order to achieve the above object, the technical solution of the utility model is as follows:
A kind of frequency converter comprises: lower house, transformer and fan; Radiator is fixed on the described lower house; Power model is fixed on the described radiator; Power amplifier board is fixedlyed connected with described power model; Capacitor board is welded with electrochemical capacitor on it; Described capacitor board is fixedlyed connected with power amplifier board and is vertical mutually; Capacitor board is fixed on the frequency converter lower house.
Power amplifier board becomes the inverted L shape graft structure with capacitor board along radiator, has made full use of the frequency converter inner space, good heat dissipation effect, and the capacitive environment temperature is reasonable.
Described fan is fixed on the lower house, over against electrochemical capacitor and radiator.Can make electrochemical capacitor like this in the fan sphere of action, thereby arrive power component and the good effect of electrochemical capacitor ventilation and heat.
