Fig. 2 is the structural representation of cooling system of the variable frequency control cabinet of the utility model embodiment.
Embodiment
The utility model embodiment directly introduces variable frequency control cabinet inside by the cold wind that cold wind generator is produced, and the equipment in the variable frequency control cabinet is cooled off, and makes cold wind effectively deliver to the heat radiation purpose, realizes purpose energy-conservation, efficiently radiates heat.
See also Fig. 1, the cooling device of the utility model embodiment variable frequency control cabinet is used to cool off frequency converter and the auxiliary device thereof in the variable frequency control cabinet 3, comprises cold wind generator 1, airduct 2 and volume control damper 4.There is interface the bottom of variable frequency control cabinet 3, and there is fan on the top.
Cold wind generator 1 is used for producing cold wind, has cold wind outlet 11, is fan coil in the present embodiment.When cold wind generator 1 was fan coil, described cold wind outlet 11 was the air outlet of fan coil.The function of cold wind generator 1 is to produce cold wind, therefore, also can use the device of any generation cold wind in the prior art, such as, adopt heat exchanger, air-conditioning.
The cold wind outlet 11 of described airduct 2 one ends and cold wind generator 1 is communicated with, an other end be connected in variable frequency control cabinet 3 the bottom interface and with variable frequency control cabinet 3 internal communication.
The course of work of the cooling device of variable frequency control cabinet shown in Figure 1 is as follows:
Cold wind generator 1 produces cold wind, the inside that this cold wind transfers to the bottom of variable frequency control cabinet 3 and enters variable frequency control cabinet 3 through airduct 2, cold wind is flowing to from the bottom the process on top then, become hot blast after frequency-variable controller in the variable frequency control cabinet 3 and auxiliary device thereof cooled off, hot blast is discharged by the fan on variable frequency control cabinet 3 tops, like this, directly frequency-variable controller and auxiliary device thereof in the variable frequency control cabinet 3 are cooled off, not that the space that the variable frequency control cabinet is placed is cooled off, therefore, cold air can effectively be delivered to the heat radiation target, realizes energy-conservation, effective cooling purpose.
Described volume control damper 4 is connected with airduct 2, is used for the cold wind that flows in the variable frequency control cabinet 3 is regulated.The cooling degree is cooling when not enough in detecting the variable frequency control cabinet, increase the air quantity of importing in the variable frequency control cabinet 3 by regulating volume control damper 4, and detect the cooling degree when being sub-cooled, reduce to import air quantity in the variable frequency control cabinet 3 by regulating volume control damper 4, thereby, the flow and the speed that flow into the cold wind in the variable frequency control cabinet 3 are regulated, and described cooling device can not crossed cold or described inadequately frequency-variable controller of cooling and auxiliary device thereof.Cooling degree in the variable frequency control cabinet is detected, can be adopted any arrangement for detecting in the prior art.According to detecting the result to described volume control damper 4, this volume control damper 4 can be manual by-pass valve control, such as, arrangement for detecting shows that the cooling degree is not enough for cooling, and then, operating personnel manually control volume control damper 4, make the air outlet of volume control damper 4 become big, and when the cooling degree is sub-cooled, manually control volume control damper 4, make the air outlet of volume control damper 4 get final product; Described volume control damper 4 also can be the valve that is subjected to arrangement for detecting control.
See also Fig. 2, the cooling system of the variable frequency control cabinet of the utility model embodiment comprises at least two cold wind generators 1, trunk airduct 5, some Zhi Ganfeng pipe 6 and some volume control dampers 4.
Described cold wind generator 1 can be fan coil, also can produce the device of cold wind for air-conditioning, heat exchanger etc.Each cold wind generator 1 comprises cold wind outlet 11.
Trunk airduct 5 is communicated with the cold wind outlet 11 of each cold wind generator 1.
The quantity of the Zhi Ganfeng of present embodiment pipe 6 and need the quantity of the variable frequency control cabinet 3 of control to equate, each dry-air blast pipe 6 one end is communicated with trunk airduct 5, and an other end is connected with the bottom interface of a variable frequency control cabinet 3 and is communicated with variable frequency control cabinet 3 inside.
In other embodiments, each root Zhi Ganfeng pipe 6 also can be communicated with two or more variable frequency control cabinets 3, for instance, each root Zhi Ganfeng pipe 6 can have three ends, wherein an end is communicated with trunk airduct 5, and two ends are communicated with a variable frequency control cabinet 3 respectively in addition, and each root Zhi Ganfeng pipe 6 is communicated with trunk airduct 5 and two variable frequency control cabinets 3 like this, in fact, each dry-air blast pipe 6 has been subdivided into two root Zhi Ganfeng pipe again.
The course of work of the cooling system of variable frequency control cabinet shown in Figure 2 is as follows:
All cold wind generators 1 produce cold wind, cold wind enters each dry-air blast pipe 6 respectively after entering trunk airduct 5, then, Zhi Ganfeng pipe 6 is sent into cold wind in the corresponding variable frequency control cabinet 3 that is communicated with, cold wind cools off frequency-variable controller and the auxiliary device thereof in the variable frequency control cabinet 3, through after the cold and hot exchange, hot blast is discharged through the fan on variable frequency control cabinet 3 tops.
In cooling system shown in Figure 2, because each dry-air blast pipe 6 is different apart from the distance of cold wind generator 1, therefore, air quantity apart from 6 li of the near Zhi Ganfeng pipes of cold wind generator 1 is bigger, like this, makes apart from the near variable frequency control cabinet 3 of cold wind generator 3 by sub-cooled, and cool off not enough apart from cold wind generator 3 variable frequency control cabinets 3 far away, certainly, the distance here can be understood as Zhi Ganfeng pipe 6 and connects the end of bottom interface of variable frequency control cabinets 3 and the distance of trunk airduct 5.In order to address the above problem, can on each dry-air blast pipe 6, volume control damper 4 be installed, when cold wind inflow Zhi Ganfeng manages 6, by regulating volume control damper 4, can regulate the flow and the speed that flow in the variable frequency control cabinet 3, thereby, avoid in the variable frequency control cabinet 3 by sub-cooled or cool off not enough phenomenon.
Though the utility model with preferred embodiment openly as above; but it is not to be used for limiting claim; any those skilled in the art are not in breaking away from spirit and scope of the present utility model; can make possible change and modification, therefore protection range of the present utility model should be as the criterion with the scope that the utility model claim is defined.
