Abstract

The three-chamber outdoor cabinet is composed of a rainproof cap, a heat dissipation chamber, a filter, a heat dissipation hole, a cabinet body, an upper partition, a device room, a lower partition, and an air inlet chamber. It is characterized in that the upper end of the cabinet is equipped with a rainproof cap. The upper interior of the cabinet is provided with an upper partition, the lower interior of the cabinet is provided with a lower partition, the upper side of the upper partition is provided with a heat dissipation chamber, the lower side of the lower partition is provided with an air inlet chamber, the upper partition and the lower partition A device room is arranged between them, heat dissipation holes are arranged on both sides of the heat dissipation chamber and the air inlet chamber, and filter screens are arranged on the inner side of the heat dissipation holes. The dust and heat dissipation scheme can effectively dissipate heat, prevent dust and rain, and can well adapt to the field environment, enhance the stability of the inverter, and increase the service life of the inverter.

Description

The outer rack of three chambers

Technical field

The utility model relates to the frequency conversion control technique field, says more specifically the outer rack of a kind of three chambers.

Background technology

The frequency-conversion control cabinet of prior art, generally be that frequency converter, low-voltage electrical apparatus and automatic controller are assembled in the cabinet, structural design is unreasonable, does not design special heat radiation, dustproof, rainproof scheme, can not effectively dispel the heat, prevents dust, rainproof, can not adapt to well wild environment, affect the normal use of frequency converter, usually caused the performance index of frequency converter to descend cisco unity malfunction, not only increase maintenance cost, and shortened the useful life of frequency converter.

Summary of the invention

For addressing the above problem, the utility model has designed a kind of heat radiation that has, dustproof, rainproof scheme, can adapt to well wild environment, the outer rack of three chambers of long service life, concrete scheme of the present utility model is: the outer rack of described three chambers is by rainhat, heat dissipation chamber, screen pack, louvre, cabinet, upper spacer, the device chamber, lower clapboard, inlet air plenum forms, the upper end that it is characterized in that cabinet arranges rainhat, the inner upper side of cabinet arranges upper spacer, the inner lower of cabinet arranges lower clapboard, the upside of upper spacer arranges heat dissipation chamber, the downside of lower clapboard arranges inlet air plenum, the device chamber is set between upper spacer and the lower clapboard, the both sides of heat dissipation chamber and inlet air plenum arrange louvre, and the inboard of louvre arranges screen pack.

The beneficial effects of the utility model are that the outer cabinet structure of three chambers is simple, easy to make, are designed with rainproof, dustproof and heat sink conception, can effectively dispel the heat, prevent dust, rainproof, can adapt to well wild environment, strengthen the frequency converter stability, improve the useful life of frequency converter.

Description of drawings:

Accompanying drawing 1 is the utility model structural representation; In the accompanying drawing:

1. rainhat, 2. heat dissipation chamber, 3. screen pack, 4. louvre, 5. cabinet, 6. upper spacer, 7. device chamber, 8. lower clapboard, 9. inlet air plenum.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail, so that the public grasps implementation method of the present utility model better, the concrete scheme that the utility model is implemented is: the outer rack of described three chambers is by rainhat 1, heat dissipation chamber 2, screen pack 3, louvre 4, cabinet 5, upper spacer 6, device chamber 7, lower clapboard 8, inlet air plenum 9 forms, the upper end that it is characterized in that cabinet 5 arranges rainhat 1, the inner upper side of cabinet 5 arranges upper spacer 6, the inner lower of cabinet 5 arranges lower clapboard 8, the upside of upper spacer 6 arranges heat dissipation chamber 2, the downside of lower clapboard 8 arranges inlet air plenum 9, between upper spacer 6 and the lower clapboard 8 device chamber 7 is set, the both sides of heat dissipation chamber 2 and inlet air plenum 9 arrange louvre 4, and the inboard of louvre 4 arranges screen pack 3.

The beneficial effects of the utility model are that the outer cabinet structure of three chambers is simple, easy to make, are designed with rainproof, dustproof and heat sink conception, can effectively dispel the heat, prevent dust, rainproof, can adapt to well wild environment, strengthen the frequency converter stability, improve the useful life of frequency converter.
