The water circulating device of the water-cooling frequency converter has the beneficial effects that: 1. the heat exchange efficiency can be increased through the water circulating device, thus the heat radiation effect of the frequency converter is improved, one water circulating pump and one deionized exchanger are additionally added for later use, and the downtime of the frequency converter is shortened, which is good for the operation and using of the frequency converter; and 2. the water circulating device of the water-cooling frequency converter is simple in structure, is convenient to implement and manufacture, and is good for market competition.

Description

A kind of water circle device of water-cooled frequency converter
[technical field]
The utility model relates to a kind of water-cooled frequency converter, the water circle device of the water-cooled of saying so more specifically frequency converter.
[background technology]
Existing frequency converter generally all is to adopt air-cooled heat dissipation structure; Because this radiator structure receives the circulation of air velocity effect, often radiating effect is not very desirable, especially in the module of frequency converter; Because electronic component is provided with more; Be easy to generate high temperature during use,, be prone to cause fault such as electronic component is impaired if radiating effect is bad.
Therefore, the applicant has done further improvement on existing frequency converter basis, wind-cooling heat dissipating has been increased the water-cooling structure, makes the radiating effect of frequency converter better.For the water-cooled medium can recycle, and speed water-cooled speed and efficient, on the water-cooled frequency converter, increased water circle device.
[utility model content]
The purpose of the utility model provides a kind of water-cooled medium circulation that makes and uses, and radiating rate and the high water circle device of efficient.
For achieving the above object, the utility model adopts following technical scheme:
A kind of water circle device of water-cooled frequency converter includes shell, it is characterized in that being provided with control cabinet and circulating line in the enclosure, and on circulating line, is connected with deionization interchanger, circulating water pump, replenisher tank and swelling water tank.
The water circle device of aforesaid a kind of water-cooled frequency converter is characterized in that on the said circulating line and is connected with two ion-exchangers.
The water circle device of aforesaid a kind of water-cooled frequency converter is characterized in that on the said circulating line and is connected with two circulating water pumps.
The water circle device of aforesaid a kind of water-cooled frequency converter; The both sides that it is characterized in that said shell are respectively equipped with inlet and outlet pipe lines that is connected with frequency converter and the inlet and outlet pipe lines that is connected with heat exchanger, and said inlet and outlet pipe lines is connected with circulating line respectively.
The water circle device of aforesaid a kind of water-cooled frequency converter is characterized in that in housing, also being provided with small pump, and said small pump is connected with replenisher tank.
The beneficial effect of the utility model has: 1, pass through water circle device; Can increase heat exchanger effectiveness, thereby improve the radiating effect of frequency converter, circulating water pump and deionization interchanger are provided with two one respectively and are equipped with a usefulness; Reduce the downtime of frequency converter, helped the work and the use of frequency converter; 2, simple in structure, be convenient to implement to make, help market competition.
[description of drawings]
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated;
Fig. 1 is the utility model sketch map;
Fig. 2 removes the schematic perspective view behind the shell for the utility model;
[embodiment]
As shown in the figure; The water circle device of a kind of water-cooled frequency converter of the utility model indication; Include shell 1, it is characterized in that in shell 1, being provided with control cabinet 2 and circulating line 3, and on circulating line 3, be connected with deionization interchanger 4, circulating water pump 5, replenisher tank 6 and swelling water tank 7.
The optimal way of the utility model is: on circulating line 3 and be connected with two deionization interchangers 4; The effect of said deionization interchanger 4 is: for adapting to the instructions for use of large power power electronic appliance under high voltage condition; Prevent under high voltage environment, to produce leakage current, coolant must possess high resistivity.
The optimal way of the utility model is: on circulating line 3 and be connected with two circulating water pumps 5 power for water recirculation is provided, be the reliability that improves system, two circulating water pumps 5 one are equipped with a usefulness, therebetween alternately can be regularly to switch; Can also be according to discharge auto switching under control system detects when fault is arranged.Recirculated water flows into and flows out the laggard inlet of going into water pump of the electronic installation that is cooled, and water pump provides power, and recirculated water flows into heat exchanger, and hot water here is cooled, and cooled water gets into the device that is cooled again and takes away heat, gets back to the inlet of water pump.
The both sides of said shell 1 are respectively equipped with the inlet and outlet pipe lines 8 and the inlet and outlet pipe lines that is connected with heat exchanger 9 that is connected with frequency converter, and said inlet and outlet pipe lines 8,9 is connected with circulating line 3 respectively.In housing 1, also be provided with small pump 10, said small pump 10 is connected with replenisher tank 6.
In the present embodiment, the effect of said swelling water tank 7 is: in closed-loop water system, played the effect of equilibrium water amount and pressure, avoided frequent unlatching of safety valve and the frequent moisturizing of automatic water compensating valve etc.In addition; In water system, swelling water tank can also reduce the Fraquent start of water pump, can be used for absorption system to open and close caused impact of water hammer because of valve, water pump etc.; And thereby a small amount of moisturizing at night makes the dormancy of water system main pump reduce electricity consumption, prolongs water pump useful life etc.
The utility model through water circle device, can increase heat exchanger effectiveness in use; Thereby improve the radiating effect of frequency converter; Circulating water pump 5 is provided with two one respectively with deionization interchanger 4 and is equipped with a usefulness, has reduced the downtime of frequency converter, helps the work and the use of frequency converter.
