Description

Controller switching equipment cabinet ventilation and heat structure

Technical field

The utility model belongs to the technical field more particularly to a kind of controller switching equipment cabinet ventilation and heat of controller switching equipment cabinet Structure.

Background technique

Controller switching equipment cabinet includes the cabinet cabinet of electric power switchgear assembly cabinet, automation control appliance, is widely applied In the computer room of factory, business cell etc..The protection level requirements of controller switching equipment cabinet are higher, generally need higher heat dissipation Air-conditioning requirement, while also needing to have good dustproof and waterproof function.However, existing controller switching equipment cabinet consider meet it is above-mentioned When functional requirement, the problem and contradiction of following all various aspects can be encountered: one, due to the places such as factory, business cell and computer room cun Native cun of gold, it requires that the volume of controller switching equipment cabinet is small and exquisite as far as possible, corresponding radiation ventilator also requires to be designed as far as possible It is relatively thin；Two, it generally requires towards the exhaust outlet outside cabinet as horizontally toward, and is generally required towards the air inlet in cabinet towards main Electric component, therefore also require as horizontally toward.In order to cater to above-mentioned both sides requirement, the ventilation of existing controller switching equipment cabinet Radiator structure mostly uses louvre ventilation grid directly to enter the structure type directly gone out plus horizontal fan, and this structure type exists logical Wind heat dissipation and dust-proof contradiction, i.e., its dust-proof effect of the good structure of result of ventilating heat dissipation is with regard to poor, and vice versa；In addition, this knot There is also the contradictions of ventilation and heat and waterproof for configuration formula, specifically, the once extraneous water there are the water droplet of sputtering, then sputtered Drop is easy to enter the inside of controller switching equipment cabinet by shutter exhaust outlet.

Utility model content

A kind of controller switching equipment cabinet ventilation and heat structure is provided the purpose of the utility model is to overcome disadvantages mentioned above, it Result of ventilating heat dissipation is good, and can be dust-proof, and the water droplet that more can effectively prevent extraneous sputtering enters interior of equipment cabinet.

Its purpose can be realized by following scheme: a kind of controller switching equipment cabinet ventilation and heat structure, including cabinet body, cabinet body are set There is cabinet body side wall, be mainly characterized by: being equipped with rectangle mounting hole in the lower part of wherein one side cabinet body side wall；Rectangle mounting hole is embedding Air guide box equipped with flat and thin, air guide box has cassette bottom wall, box roof and four sides box side wall up and down, wherein towards cabinet The box side wall in external face is known as front side wall of the box body, and the air guide box side wall opposite with front side wall of the box body is known as box body rear wall；Cabinet The vertical height of body rectangle mounting hole is equal to air guide box box roof to the vertical distance between cassette bottom wall lower edge, the installation of cabinet body rectangle The transverse width in hole is equal to air guide box box body left side wall to the lateral distance between box body right side wall；The surrounding of front side wall of the box body Along convex edge is formed with, convex edge againsts the surrounding edge of cabinet body rectangle mounting hole；

Box body rear wall center is equipped with round suction opening, is equipped with eddy current type centrifugal blower in air guide box box chamber, the whirlpool The air intake surface of flow centrifugal blower faces the round suction opening of box body rear wall, and round suction opening faces cabinet body inner cavity, box Body front side wall lower part offers rectangle exhaust outlet, and the vertical position of the minimum point of round suction opening is arranged higher than front side wall of the box body rectangle The highest point in air port；The box body left side wall of air guide box, box body right side wall, box roof, the sealing of cassette bottom wall, cassette bottom wall is by interior lateral Outer downside inclination；Front side wall of the box body rectangle exhaust outlet left and right side along be equipped with the vertical clip slot of twice, the vertical clip slot of twice it Between be fitted with the filtering cotton component of rectangle, which includes the filtering cotton of rectangle and the rigid border of rectangle, The surrounding edge of filtering cotton is fixed by rigid border, and the rigid border of two sides is respectively inserted in the vertical clip slot of twice.

The rigid border of the filtering cotton component includes inside casing and outline border, and the section of outline border forms rectangular inner corner trim, Inside casing is tightly embedded in the internal corner part of outline border, and the edge of the filtering cotton is sandwiched between inside casing and outline border.

By interior upside, the inclined angle in downside is 40 °~50 ° to cassette bottom wall outward.

The utility model has the following advantages that and effect:

One, the vertical position of the utility model exhaust outlet be lower than suction opening vertical position, while make again air draft direction into Row turns round twice and ensures that the direction of exhaust outlet and suction opening all remains level for 90 °, in this way, on the one hand may insure that the external world is splashed The droplet for entering exhaust outlet will not be further continued for entering interior of equipment cabinet by suction opening, on the other hand can ensure that high efficiency and heat radiation again.

Two, the utility model uses eddy current type centrifugal blower, not only improves natural 90 ° of turns of airflow direction, and advantageous In keeping the figure of entire heat dissipation equipment more flat thin.

Three, the utility model can ventilation and heat and dust-proof, and the replacement of filtering cotton is convenient, as long as will filtering Cotton component is extracted out between the vertical clip slot of twice, and the inside casing of filtering cotton component and outline border are separated, so that it may remove old mistake Filter pulp cloth and load onto new filtering cotton, then inside casing is embedded in outline border again, filtering cotton component is finally turned back into twice and is erected To between clip slot.
