it is this IGBT power model cooling device that the utility model solves the problems of the technologies described above adopted technical scheme, includes liquid cooling apparatus, and its architectural feature is also to include: a, extractor fan, and described extractor fan is arranged on power model top; B, heat-exchanger rig, described heat-exchanger rig is arranged on power model bottom; C, air channel, described air channel is arranged on power model inside, and described extractor fan is connected by described air channel with described heat-exchanger rig; D, filter, described filter is arranged on described air channel air inlet front end; E, induction controller, described induction controller is arranged in described air channel.Due to air expanded by heating, itself just there is the trend of certain rising, therefore save the energy consumption of extractor fan.Filter has ensured the clean of cold wind, reduces the damage of impurity to element in air, and covers the impact of dirt on heat radiation.Induction controller can be according to the speed of service of the temperature control extractor fan in air channel, has ensured that the temperature in air channel can be not too high, more energy-conservation.
as preferably, extractor fan described in the utility model is axial flow blower.
as preferably, heat-exchanger rig described in the utility model is air-water heat exchanger.
as preferably, filter described in the utility model is nylon leaching net, and nylon leaching net is simple in structure, with low cost, is applicable to the cleaner area of air.
as preferably, filter described in the utility model is active carbon, in the higher area of suspended particulate matter concentration, uses activated carbon filtration air can effectively extend element useful life.
the utility model compared with the existing technology has the following advantages and effect: 1,, owing to being provided with air channel in IGBT power model inside, inner auxiliary element can directly be obtained air-cooled; 2, the discharge that is conducive to hot blast setting up and down of axial flow blower and heat exchanger, has reduced the power consumption of axial flow blower, has reduced electric cost; 3, the design of filter makes cooling-air more clean, and auxiliary element is not easy to cover dirt, thereby has extended the life-span of auxiliary element; 4, induction controller can be according to the rotating speed of the change regulating shaft flow fan of temperature in air channel, makes the temperature in air channel can be not too high.
Brief description of the drawings
in order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
fig. 1 is work schematic diagram of the present utility model.
label declaration: air-water heat exchanger 10, IGBT power model 20, axial flow blower 30, Electric Appliance Cabinet cabinet 40, air channel 50, filter screen 60, induction controller 70, liquid cooling pipe network 80, heat exchange interchanger 90.
Embodiment
below in conjunction with embodiment, the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
embodiment 1: as shown in Figure 1, the present embodiment is made up of air-water heat exchanger 10, IGBT power model 20, axial flow blower 30, regulator cubicle cabinet 40, air channel 50, filter screen 60, induction controller 70, liquid cooling pipe network 80, heat exchange interchanger 90.
filter screen 60 is arranged on air-water heat exchanger 10 air inlet places, it is mainly nylon leaching net, the area higher at suspended particulate matter concentration is replaced into active carbon filter screen, air-water heat exchanger 10 is arranged on IGBT power model 20 belows and is connected with air channel 50, air channel 50 is arranged on IGBT power model 20 inside, all heating auxiliary elements are passed through in the design in air channel 50 as far as possible, axial flow blower 30 is arranged on IGBT power model 20 tops and is connected with air channel 50, axial flow blower 30 tops communicate with regulator cubicle cabinet 40 gas outlets, and gas outlet is arranged on regulator cubicle cabinet 40 tops.Induction controller 70 is arranged on the 50 the most concentrated places of internal heat generation element, air channel, is connected with axial flow blower 30, rotating speed that can Control Shaft flow fan 30.Liquid cooling pipe network 80 and heat exchange interchanger 90 form liquid cooling apparatus common in prior art, and liquid cooling pipe network 80 is closely enclosed in IGBT power model 20 skins.
air channel of the present utility model adopts the cooling method of exhausting, when work, axial flow blower 30 is enabled in 50 tops, air channel and forms negative pressure, air enters air-water heat exchanger 10 from the filter screen 60 of bottom, enter air channel 50 through supercooling, carry out the heat exchange of forced air cooling with the auxiliary element such as device, copper bar in IGBT power model 20, air themperature rises gradually subsequently, through the axial flow blower 30 at top, discharges IGBT power model 20.After hot-air is extracted IGBT power model 20 inside out, because the air pressure in air channel 50 reduces, bottom air-water heat exchanger 10 is by outside air intake, through heat exchange, the hot air temperature sucking reduces, the components and parts of cooling IGBT power model 20 inside again, so circulation.In the time that induction controller 70 detects air channel 50 interior excess Temperature, improve intake velocity by accelerating the rotating speed of axial flow blower 30, thereby the temperature that ensures IGBT power model 20 interior auxiliary elements is lower than 40 ambient temperature in regulator cubicle cabinet.
