Abstract
The utility model discloses a water cooling device for an explosion-proof frequency converter, which comprises an explosion-proof casing and a water cooling device placed in the explosion-proof casing. The water cooling device is composed of at least one fan and an air cooler, wherein each fan is positioned at the bottom of the explosion-proof casing, and the air cooler is placed above the fans. A heater in a frequency converter is arranged between each fan and the air cooler; each fan transfers heat emitted by the heater in the frequency converter to the air cooler; and the air cooler transfers the heat to the outside of the explosion-proof casing by the aid of cold water circulation inside the air cooler. The technical scheme of the water cooling device for an explosion-proof frequency converter includes that the axial-flow fans and the air cooler are mounted in the explosion-proof casing and combined for use, and the heat emitted by the heater in the explosion-proof casing can be effectively transferred to the outside of the explosion-proof casing. The water cooling device for an explosion-proof frequency converter is used for cooling the high-power frequency converter, and has the advantages of better heat pipe cooling mode outside the explosion-proof casing and better water cooling mode outside the explosion-proof casing.

Background technology
Along with the continuous development of power electronic technology, variable-frequency control technique is increasingly mature, and universal frequency converter has obtained developing rapidly, and all trades and professions of the frequency converter of various brands in the automatic control field have all obtained using widely.But having many places of damp and dust (colliery coke-oven plant part chemical plant) and high-tension electric motor to drag local frequency converter at some is not also used fully, trace it to its cause mainly is that these local frequency converters need be explosion-proof, the frequency converter principle is to finish change to the power frequency supply frequency by rectification and inversion transformation technique, and the caloric value of the power device of rectification and inversion is big, if handle bad heat dissipation problem, frequency converter can't operate as normal.
At present, the radiating mode that is mainly used in the flame-proof converter field has heat pipe heat radiation mode and water cooling method, the heat pipe heat radiation mode mainly relies on the copper coin that connects power device with the heat transferred heat pipe, thereby reach the purpose that reduces flame proof enclosure interior temperature, the operate as normal of holding power device; Also having a kind of mode is to adopt water cooling method, present water cooling method is that cooling line is attached to the outside copper coin surface that connects power device, being and the close mode of heat pipe heat radiation mode cooling principle, mainly is by the outer loop of cooling water the heat in the housing to be taken away.
Above-mentioned two kinds of radiating modes are applied under small-power, the low-voltage environment, can satisfy the operation needs of frequency converter substantially, and still, for high voltage, high-power, explosion-proof frequency conversion device, above-mentioned two kinds of radiating modes just can not be kept effective operation of frequency converter.
Summary of the invention
Technical problem to be solved in the utility model is the heat dissipation problem of explosion-proof frequency converter power device.
In order to solve the problems of the technologies described above, the utility model provides a kind of water cooling plant that is used for explosion-proof frequency converter, comprises flame proof housing and the water cooling plant that is built in the flame proof housing,
This water cooling plant is to be positioned at the blower fan of explosion-proof casing bottom and one by at least one to place the aerial cooler of this blower fan top to constitute, and is the heater in the frequency converter between described blower fan and the aerial cooler;
Described blower fan is given aerial cooler with the heat delivery that frequency converter internal heat generation body is distributed;
Described aerial cooler arrives the flame proof outside by its inner cold water circulation with heat transferred.
Further, the water inlet port of described aerial cooler connects a temperature sensor, and this temperature sensor is used to monitor the state of temperature of cooling water, and state of temperature is sent to controller.
Further again, described aerial cooler is the fin chimney cooler.
As a kind of preferred version,, the cooling line of described fin chimney cooler is a stainless steel tube, the fin of this fin chimney cooler is the aluminum fin.
Further, described blower fan is the low noise explosion-proof axial flow fan.
The beneficial effects of the utility model are:
1, technical solutions of the utility model are taked at flame proof enclosure interior installation shaft flow fan and aerial cooler, and it is used in combination, the heat that can effectively flame proof housing internal heat generation body be distributed takes the flame proof outside to, be used in big-power transducer heat radiation aspect, effect both had been better than also being better than at the external water cooling method of flame proof housing in the external heat pipe heat radiation mode of flame proof housing.
2, the radiating mode of technical solutions of the utility model can be used in the heater both sides and dispel the heat, and compares not only good heat dissipation effect, and the structural design of convenient frequency converter each several part device with the one-sided radiating mode of prior art.
3, the disclosed radiating mode of technical solutions of the utility model has been broken through the Design Thinking set that existing flame proof outside is dispelled the heat, and in flame proof heat radiation field, has opened up a new approach.
Below in conjunction with the drawings and specific embodiments technical solutions of the utility model are described in further detail.
