Described water-cooled power cell 11 also comprises power supply input port 111 and power output 112, for power-on servicing;
Preferably, described cooled plate 113 is the good aluminium of heat conduction efficiency.
Operation principle: the heat exchange of described water-cooling frequency converter is mainly adopted in two ways and combined:
1) the first is the external heat-exchanging of frequency-charger cabinet whole inner space heat exchange, as shown in Figure 5: refer to that the cooling water that Water-cooled cabinet 1 the inside is produced is by the outer water inlet pipe 51 in outer water pipe road 5 surface cooler 7 of flowing through, the fin of surface cooler 7 inside makes the air of flowing through cooling, the cold air after cooling is delivered to frequency converter inside by blower fan 42, cooling water flows out, by water return pipeline 52 outer water pipe road 5, absorbed heat is taken back to Water-cooled cabinet 1 from surface cooler 7, after emitting heat, cooling, be sent back to again surface cooler 7, surface cooler 7 absorbs heat, the air of cool stream warp, constantly circulation.
In addition, frequency converter inside also exists wind direction to flow and the process of heat exchange, as shown in the arrow in Fig. 5: be mainly the heat that frequency converter inner heat device is produced, drive wind speed mobile by blower fan, by the hot air flow surface cooler that stimulated the menstrual flow, surface cooler is walked the heat absorption in hot blast, change cold wind into and continue circulation, cold air is taken away heat through inner heat device, becomes hot blast, by blower fan upwards the suction surface cooler of flowing through turn cold, circulation and so forth.
2) the second is the inside heat exchange to frequency-charger cabinet internal heating element (water-cooled power cell 11) heat radiation, as shown in Figure 6: heat exchange mode and external heat-exchanging that it adopts are basic identical, cooling water that Water-cooled cabinet 1 the inside is produced by the flow through cooled plate 113 of water-cooled power cell 11 inside of inner conduit road 6, cooling water is taken back Water-cooled cabinet 1 by the heat in cooled plate 113 by water circulation, after emitting heat, cooling, be sent back to again water-cooled power cell 11 and absorb heat, constantly circulation; The heat radiation of water-cooled power cell 11 mainly refers to the heat radiation of its Primary Component, and heater members is mainly arranged in cooled plate, and heater members produces after heat, conduct and conduct heat in cooled plate 113 by heat, cooled plate 113 is aluminium, and heat conduction efficiency is relatively good, then by cold water, heat is taken away.
Advantage of the present utility model and beneficial effect: the utility model, compared with traditional air-cooled variable-frequency device, need to, from the outside air intake of cabinet, not remove outside Inlet Network, has reduced the process of artificial periodic replacement, cleaning and filtering net; The noise producing when water-cooling frequency converter work is less; Reduce because the damage of outside rugged environment to frequency conversion tank internal components makes the frequency converter life-span longer; In the installation of frequency converter, arrange air channel without site operation personnel, time saving and energy saving.
