Background
With the wide application of frequency converters in industry, the environment of use is more and more diversified and complicated, and especially in the occasion of more dust, the dust is sucked into the air duct of the frequency converter and can be attached to the radiator. If the dust is not cleaned immediately, the air duct is blocked, so that the temperature of the frequency converter is raised, and overheating protection is caused; if dust enters the charged part, once being affected with damp, the phenomena of arc discharge and short circuit can be caused; if conductive dust is introduced, it can directly result in a fryer. Therefore, in the occasion of more dust, design a converter that dustproof radiating effect is good, it is imperative. However, the professional dustproof frequency converter has the disadvantages of high price, large volume and high cost for enterprises.
The failure rate of the frequency converter increases exponentially along with the temperature, the service life of the frequency converter decreases exponentially along with the temperature, and if the heat dissipation problem of the frequency converter is not well treated, the service state and the service life of the frequency converter are affected, and even the frequency converter is damaged.
SUMMERY OF THE UTILITY MODEL
Need and improve the weak point of prior art more than to, the utility model provides a low price, it is convenient to maintain, dustproof effectual converter to optimize its wind channel in practical application.
In order to solve the problem, the utility model relates to a wind channel structure of embedded converter in the cabinet body in independent wind channel, include rack, rack baffle, rack bottom plate, rack roof, embedded converter about, the lacing wire. The embedded frequency converter is a frequency converter with an independent air duct, namely, the self heat dissipation air duct and the charged part of the frequency converter are mutually independent. The left and right hanging strips are fixed on the embedded frequency converter and separate the independent air channel parts. The cabinet partition plate divides the cabinet into a first cavity and a second cavity which are completely independent from each other, the first cavity and the second cavity are mutually sealed, a through hole matched with the embedded frequency converter is formed in the cabinet partition plate, and a threaded hole or a through hole for fixing the left hanging strip and the right hanging strip is formed in the cabinet partition plate. An exhaust fan can be arranged at the air outlet of the top plate of the cabinet. During normal operation, air flow enters from an air inlet hole of a cabinet bottom plate at the lower part of the cavity, passes through the embedded frequency converter of the independent heat dissipation air duct and is discharged from an air outlet hole of a cabinet top plate.
By adopting the structure of the technical scheme, the left side surface, the right side surface and the bottom surface of the lower part of the embedded frequency converter are respectively provided with the air inlet holes, the air inlet holes are matched with the fan to form independent air channels and are arranged in the first cavity of the cabinet, and the left side surface and the right side surface of the upper part of the embedded frequency converter are provided with the convection heat dissipation holes and are arranged in the second cavity of the cabinet.
The bottom plate of the cabinet adopting the structure is provided with an air inlet hole for radiating the embedded frequency converter of the independent air channel, and the top plate of the cabinet is provided with an air outlet hole for hot air of the embedded frequency converter of the independent air channel to flow out.
As an improvement aiming at the technical scheme, the air inlet and outlet holes of the bottom plate or the top plate of the cabinet are not limited to a geometric shape under the condition of meeting the requirement of protection grade.
As another improvement aiming at the technical scheme, the combination body of the left and right hanging strips and the embedded frequency converter just covers the through hole which is formed in the partition plate of the cabinet and into which the embedded frequency converter sinks.
The sunk through hole of the embedded frequency converter arranged on the partition plate of the cabinet can be larger than that of the embedded frequency converter of the independent air channel, and the peripheral gaps can be filled with dense glue, foam or pasted with sealing adhesive tapes.
For the air inlet hole of the bottom plate of the cabinet, a space should be reserved on the cabinet by adding a support leg or suspending.
Of course, the utility model discloses the rack can be electric computer lab's high-low voltage cabinet, switch board, also can settle a plurality of converters in the cabinet, has reached dustproof heat dissipation, and the structure is succinct, convenient operation, reduce cost's purpose.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings.
Fig. 1 is an exploded perspective view of an air duct structure of a frequency converter in a cabinet body according to the present invention.
Fig. 2 is a perspective view of the independent duct built-in cabinet duct of the embedded frequency converter shown in fig. 1.
Detailed Description
Fig. 1 shows the hole position combination and fixation relationship between the casing of the embedded frequency converter 5 and the left and right hanging strips 6 of the bent sheet metal part, and the installation relationship between the assembly of the embedded frequency converter and the rectangular hole of the cabinet partition plate 2 through the left and right hanging strips 6. The fresh air inlet 7 is including controlling side and bottom surface, and 9 convulsions of fan form the utility model discloses embedded converter 5's independent wind channel, because the heat dissipation wind channel and the electrified position mutual independence of embedded converter 5 in independent wind channel, so electrified position does not have the forced air of positive, negative pressure and flows, can only lean on natural convection and radiation heat dissipation.
Fig. 2 shows an air duct formed by the first cavity 10 in the cabinet 1 and an air direction, and since the first cavity 10 and the second cavity 11 of the cabinet 1 are sealed with each other, during normal operation, air flows enter from the cabinet bottom plate 3 at the lower part of the first cavity 10, passes through the embedded frequency converter 5 of the independent air duct, and is discharged from the cabinet top plate 4. And because the two side surfaces of the electrified part of the embedded frequency converter 5 are provided with the convection heat radiation holes 8, the high temperature in the embedded frequency converter 5 can carry out convection heat exchange with the inside of the second cavity 11 of the cabinet 1 through the convection heat radiation holes 8, thereby reducing the temperature rise of the electrified part of the embedded frequency converter 5 and preventing dust from entering the electrified part of the frequency converter.
To sum up, the utility model discloses two wind channels of independent wind channel and the 2 divided rack cavity of rack baffle of embedded converter 5 self have guaranteed radiating channel's noncongestion, can implement effectual protection to the converter operation that produces heat by the internal loss.
