Description
Technical field
The utility model relates to a kind of modular construction form of power electronic device, refers in particular to the cooling structure form of a kind of driven by power with current transformer, and technology of the present utility model is mainly used in the wind-cooling heat dissipating of power converter.Belong to the manufacture technique of power electronic device field.
Background technology
Convertor assembly is the important component part that exchanges the transmission electrical system.Have many thermals source in the convertor assembly, as transformer, reactor, power resistor, power electronic device (as IGBT, GTO, IGCT) etc., they make, and temperature raises in the device cabinet.The rising of ambient temperature will make material property degradation, cause the electronic component failure rate to increase.In the thermal design process, to take measures the temperature rise in restrictor device and the cabinet at first exactly.Its principle one is to reduce caloric value, the 2nd, strengthen heat radiation, and comprise Design of for heat sinks, air-cooled design, liquid cools design etc.Compare transformer, reactor, power electronic device makes because of volume is less that thermal capacity is restricted, temperature is easily drawn high fast, and its heat dissipation problem is more outstanding, generally all takes special radiator auxiliary heat dissipation, and radiator is carried out mandatory cooling.The mode of mandatory cooling mainly contains the heat radiation of forced air cooling, cooled plate and utilizes heat-pipe radiator several modes of dispelling the heat.Wherein, air-cooledly belong to a kind of the most common form, because air-cooled to have a cooling source collection simple, can there be advantages such as leakage, therefore very general in the application of power rectifier (unsteady flow) device, but existing wind-cooling heat dissipating device all is the side air admission of taking, the version of the direct air-out of side direction, as the disclosed technology contents of Chinese patent (patent No. is 99227679.9, and name is called " the cross flow fan cooling device on the semiconductor device ").This " cross flow fan cooling device " though simple in structure, volume is also less, has the heat radiation inconsequent, has problems such as temperature gradient.Especially for large-scale power convertor assembly,
Require supporting radiator to have higher and heat dispersion that temperature gradient is littler, and will realize heat radiation in limited space, simple crossing current air cooling seems that some is unable to do what one wishes.
(patent No. is 200410073407.3 to Chinese patent, name is called the improvement of a kind of high-efficient low-noise heat sink and the common heat sink " design ") another kind of air-cooled radiator disclosed, but its " main, with the flat shape manufacturing or make spill into " by changing the flat shape of radiator with fan combination face portion fin.Fundamentally do not solve the problem that there is temperature gradient in simple laterally cooling.Therefore necessary this is further studied.
The utility model content
The purpose of this utility model is that it is better to propose a kind of radiating effect, the convertor assembly radiator structure that air inlet and air outlet temperature gradient are little at the deficiency of existing convertor assembly air-cooled radiator.
The purpose of this utility model is achieved through the following technical solutions: a kind of convertor assembly radiator structure, power electronic power device, reactor, power electronic controller spare are housed in the device case at least, and power electronic power device radiator, and radiator places in the heat dissipation wind channel of isolating with power electronic power device and power electronic controller spare, power electronic power device is isolated by dividing plate and heat dissipation wind channel, forms the power electronic power device cavity of relative closure; Power electronic controller spare is also isolated by dividing plate and heat dissipation wind channel, forms the power electronic controller spare cavity of relative closure; Make that power electronic power device chamber and power electronic controller spare cavity and air channel are three independently cavity body structures; Have the air inlet in air channel in the bottom of device case one side, have the air outlet in air channel on the top of device case opposite side, radiator places in the air duct sections between air inlet and the air outlet, the entire heat dissipation air channel is below device lower box part air inlet enters into radiator, rise to above the radiator below radiator, again via device upper box part air outlet, a formed elder generation is entered by inlet again, at the radiator place more from lower to upper, the air channel that leads to outlet again.In order to strengthen the effect of air channel cooling, be provided with in the bottom, air channel of radiator section and force wind direction pressure pressure blowing blower fan upwards.
Described convertor assembly radiator structure, owing to the type of cooling of having taked up to blow out again from the radiator bottom, can be so that the cooling effect of entire radiator reach unanimity substantially, temperature gradient can obviously descend, so cooling effect is better, and is more even.
