Description

A kind of ventilation heat abstractor
Technical field
The utility model is related to power electronic equipment technical fields, and in particular to a kind of ventilation heat abstractor.
Background technology
With a large amount of uses of the power electronic equipment on power grid, use occasion is more and more.Special electric wire outdoors The installation of the positions such as bar, column is more and more common.In order to ensure to install and use safety, the power electronic equipment volume installed on column, again Amount should not be too large overweight, it is therefore desirable to make each element size, quality small as far as possible.Since power electronic equipment is often Big power consumption electrical appliance, in order to ensure Electrical Safety, avoids the generation of pernicious electric power accident, it is ensured that power grid is efficiently and smoothly operated, needs Effective waterproof and dustproof is wanted, especially to dissipate the amount of heat of itself generation in time.
But existing power electronic equipment or wind turbine only with common shutter or is only used into stent mode It being fixed in frame and radiates, ventilation rate is low, and usually less than 40%, onsite application requirement far can not be met; Using air-conditioning heat dissipation, volume is big, and power consumption is big, with high costs, can not popularize.Likewise, air heat exchanger, although power dissipation ratio It is relatively low, but it is bulky, with high costs, it still can not extensive use.
Utility model content
The purpose of the utility model is to overcome existing power electronic equipment radiator drafting efficiency is low, volume is big, quality Big deficiency, and a kind of ventilation heat abstractor is provided.
To achieve the above object, technical solution provided by the utility model is:A kind of ventilation heat abstractor, special character It is:Including installation frame, adjustable speed fan and blinds fan, Air Filter and the cover board being successively set in installation frame;It is described Blinds fan is on the frame of the installation frame;The outer edge of the cover board and the inner wall of installation frame fit closely, institute It states and through-hole is offered on cover board, the adjustable speed fan is installed on through-hole.
Further, in order to remove the dust stratification on filter screen, above-mentioned adjustable speed fan is bidirectional speed governing wind turbine.
Further, at least one temperature sensor for being used to detect environment temperature, the temperature are additionally provided on above-mentioned cover board Degree sensor is electrically connected with adjustable speed fan, and the adjustable speed fan adjusts its rotating speed and positive and reverse steering according to the environment temperature.
Further, above-mentioned temperature sensor is four, and a temperature sensor is located at the middle part of cover board, other three temperature Spend the edge that sensor is mounted on cover board.
Further, above-mentioned adjustable speed fan is four, and four adjustable speed fan rectangular array distributions are arranged on the cover board On.
Further, above-mentioned installation frame is above and below the side of cover board or/and left and right edges are equipped with the flanging of installation, For ventilation heat abstractor to be fixedly mounted on power electronic equipment.
Further, the edge of above-mentioned cover board is equipped with groove, sealing joint strip is equipped in the groove, for divulging information Sealing between radiator and power electronic equipment.
Further, above-mentioned installation frame is rectangle or circle or ellipse or diamond shape, can flexibly be selected according to actual needs It selects.
Further, above-mentioned installation frame and cover board are stainless steel.
Compared with prior art, the utility model has the advantages that:
1st, the cover board that ventilation heat abstractor provided by the utility model uses will shelter from other gaps in addition to wind turbine, Wind can be effectively prevent short-circuit.Wind short circuit refers to that air can be flowed to the place of low wind pressure when air flows.If wind turbine is pacified Holding position is not provided with cover board and does baffle processing, and wind turbine wind outlet is higher-pressure region, is low-pressure area at air inlet, wind can be directly from air side Inlet side is flowed back to, so as to substantially reduce the working efficiency of wind turbine.
2nd, ventilation heat abstractor provided by the utility model using air cooling way radiate, greatly reduce equipment integral into This.Using bidirectional speed governing wind turbine, in low-power consumption using slow-speed of revolution energy conservation and environmental protection, wind turbine reversion can will be after longtime running Dust stratification on Air Filter is blown off, is effectively extended plant maintenance period and service life, is significantly reduced use cost.And wind turbine Quantity, model can be adjusted flexibly according to the difference of total heating power of power electronic equipment, use is quite convenient.
3rd, ventilation heat abstractor provided by the utility model, can be in the higher position of the temperature found out according to hot simulation result Multiple temperature sensors are installed, can accurately measure scene temperature data, and the rotating speed and positive and reverse steering of wind turbine are adjusted according to it.
4th, ventilation heat abstractor provided by the utility model is simple in structure, compact, and heat-sinking capability is strong, blower fan work effect Rate is high.
