Portion will form what the mounting height on opposite ground was located from low to high for vertical or have the electrical appliance kit of certain tilt angle installation
Free convection, pipe main body air-out direction setting principle be to try to it is consistent with free convection direction, to accelerate flow velocity, because
This, optionally, in the first end and second end of pipe main body 2, the mounting height of one end of air inlet is higher than the peace of one end of outlet air
Dress height, in this way, the outlet air of one end of pipe main body outlet air enters the lower of electric appliance box main body, then from the height of electric appliance box main body
Locate outlet air, into one end of the air inlet of pipe main body.
In order to reduce the local losses of air-flow, the corner of pipe main body can be set to arc, in this way, can reduce stream

The electric appliance box main body of sensor feedback carries out real-time control, that is to say, that radiating condition according to actual needs carries out the control of blower
It makes, if necessary to a large amount of heat dissipations, then the revolving speed of blower is turned up, if heat dissipation needs are lower, turn down the revolving speed of blower, not only dissipate
Thermal effect more preferably, can also save power resource.There are many adjustable strategies of the revolving speed of specific blower, is exemplified below:
For example, opening blower when the temperature of detection is greater than the set value.
Alternatively, controller is specifically used in practical application: obtaining the N number of temperature range divided in advance according to temperature height
With the corresponding relationship of the revolving speed of blower；Determine the temperature range where the temperature of detection；It is searched from corresponding relationship fixed
The revolving speed of blower corresponding to temperature range；Blower is controlled according to the rotational speed of the blower found.

In scene, it is possible to which the temperature that will appear detection alternately fluctuates (i.e. two different humidity provinces in different temperature ranges
Between toggle) situation when, blower is run under higher rotation speed, and frequent switching is easily damaged, therefore, can be until continuous
The temperature of the detection of preset times feedback, just can be using the same temperature section as finally determination in same temperature section
Temperature range.
Above-mentioned corresponding relationship may include: from the minimum temperature range of temperature to the highest temperature range of temperature, it is corresponding
Revolving speed is gradually increased.In this way, lower revolving speed is used, if electrical appliance kit master if the temperature of electrical appliance kit body interior is lower
The temperature in internal portion is higher, then uses biggish revolving speed, accelerates heat dissipation.
Different temperature ranges corresponding revolving speed the modes such as can be measured by test and be obtained.
Corresponding relationship therein can also include secondary high temperature range from the minimum temperature range of temperature to temperature, corresponding
Revolving speed be gradually increased；The revolving speed of the highest temperature range of temperature is equal with the high revolving speed of temperature range of temperature time.
For 4 temperature ranges are set, it is assumed that the maximum temperature of detection is Tmax, environment temperature TE, will test
Temperature is divided into low temperature TL, positive room temperature TN, high temperature TH, superhigh temperature THL4 sections, TE≤TL≤0.5Tmax；0.5Tmax< TN≤
0.7Tmax；0.7Tmax< TH< Tmax；THL> Tmax.Wherein, temperature range boundary choose can as the case may be depending on.
Four temperature range low temperature TL, positive room temperature TN, high temperature TH, superhigh temperature THLRespectively correspond the revolving speed n of blower1、n2、n3、
n3, n1< n2< n3.Wherein, n3It is the maximum (top) speed that blower can be born.Wherein, n1、n2It can be configured according to actual needs.
Since the revolving speed that blower can be born is limited, in the present embodiment, use blower that can bear the case where high temperature
Maximum (top) speed can not also increase speed again even if temperature is further continued for increasing, so being still to adopt for the case where superhigh temperature
The maximum (top) speed that can be born with blower avoids blower from running at high speed always to protect blower, reduces the service life.
It is especially high for the temperature of above-mentioned electrical appliance kit body interior, even if reaching the maximum (top) speed of blower, can not also expire
Sufficient cooling requirements illustrate that operating condition is especially severe at this time, unsuitable to continue booting operation, and for such situation, controller is gone back
For judging whether the fixed temperature range is continuously the highest temperature range of temperature, if fixed temperature range is held
Continue for the highest temperature range of temperature, send halt instruction to electric appliance box main body, so that electric appliance box main body executes halt instruction
It is shut down.Specifically, when judging whether the fixed temperature range is continuously the highest temperature range of temperature, specifically
: judge that the fixed temperature range is continuously the number of the highest temperature range of temperature and whether reaches preset times, if
Reach preset times, determine that fixed temperature range is continuously the highest temperature range of temperature, the settings of preset times can be with
It is depending on the circumstances, for example be 2~5 times, specifically, can be 2 times；Alternatively, also may determine that the fixed temperature
Whether the time that section is continuously the highest temperature range of temperature reaches preset time, if reaching preset time, determination is had determined that
Temperature range be continuously the highest temperature range of temperature.The duration setting of preset time can be depending on the circumstances.
In this way, stoppage protection can be carried out after electric appliance box main body receives halt instruction.
