Description
Technical field
The present invention relates to electric control cabinet field, in particular to a kind of electric cabinet with high efficiency and heat radiation labyrinth type air duct.
Background technology
A kind of electronics that electrical control cabinet is commonly used as mechanical field, want reliable operation, except to be met except the performances such as electromagnetic compatibility, usually also need satisfied two key propertys: one is that requirement possesses environmental protection performance, comprise dust-proof, anticorrosion, anti-humidity etc., therefore to be had good stopping property; Two is that requirement possesses reliable and stable thermal environment, can device temperature be controlled in allowed band, therefore have good heat-sinking capability again. And the electric cabinet of good leak tightness, its heat-sinking capability is often not enough; And the electric cabinet that heat-sinking capability is good, its stopping property is generally poor. Namely to be ensured the stopping property of electricity cabinet, ensure good heat radiating again, then become structure design urgent problem.
At present, market adopts usually air-conditioning or heat exchanger solve this technical contradiction, but still there is the deficiency in some technology. Being embodied in: the contradictory problems of heat exchanger body sum exchange capability of heat, volume is little, and exchange capability of heat is on the low side; Exchange capability of heat is strong, and volume is relatively big again, therefore the volume of impact electricity cabinet; And air-conditioning is on the high side, economy is not good, does not usually adopt.
Traditional electric cabinet is difficult to solve sealing, heat radiation, contradiction between volume and cost, therefore, design a kind of there is high efficiency and heat radiation, high-seal, novel electricity cabinet with low cost, compact type become demand too impatient to wait.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of electric cabinet with high efficiency and heat radiation labyrinth type air duct, this electricity cabinet is compact, have high-seal performance and high efficient heat dissipation performance.
The technical scheme of the present invention is: a kind of electric cabinet with high efficiency and heat radiation labyrinth type air duct, comprise cabinet, appliance mounting panel and multiple scatterer, cabinet bottom is provided with the transformer room installing transformer, appliance mounting panel is located at inside cabinet, and between appliance mounting panel and cabinet, form box channel, it is connected with transformer room bottom box channel and forms main air duct, box channel has some insulated chambers; The side that appliance mounting panel is relative with box channel is distributed with multiple scatterer, independent point air channel it is provided with in each scatterer, the air port that goes out in each point of air channel is connected with main air duct, the blast inlet in each point of air channel is connected with insulated chamber, insulated chamber is through main air duct, and be connected with outside cabinet again with after main air duct exclusion seal, 2-3 point air channel entrance can be provided with in each insulated chamber.
The side of described scatterer arranges heat-generating units, and another side of scatterer arranges the air gathering plate of indent, forms mazy point of air channel between air gathering plate and scatterer, and the blast inlet in point air channel goes out, with point air channel, the two ends up and down that air port lays respectively at scatterer. Wherein, air gathering plate is designed to concave inward structure, from cabinet, enters insulated chamber at freezing air, then after entering point air channel from the blast inlet in point air channel, air gathering plate compressed air stream, makes the freezing air wind speed on heat-generating units place scatterer accelerate, significantly carry high cooling efficiency.
Forming " recessed " shape space vertically placed between described air gathering plate and scatterer, spreader surface is distributed with some projection pieces, and " recessed " shape spatial separation is become mazy point of air channel by projection piece. Duct design will be divided to become maze-type structure, and the surface heat radiation that can make scatterer evenly, extends freezing air in the residence time of spreader surface, thus improves its heat radiation efficiency.
The air inlet in described point of air channel is provided with isolation ring, and isolation ring two ends are tightly connected with appliance mounting panel and cabinet respectively, and the space that isolation ring isolates in main air duct is insulated chamber. By isolation ring by the blast inlet in point air channel and main air duct exclusion seal, to ensure the stopping property in point air channel, prevent the mixing of cold and hot wind and affect radiating effect.
The blast inlet in described point of air channel and the junction of appliance mounting panel are provided with rubber ring, and the junction going out air port and appliance mounting panel in point air channel is also provided with rubber ring. The blast inlet in point air channel and point air channel go out air port all with rubber ring gluing, sealing, make the electric mounting space in whole air channel and cabinet completely isolated, ensure its radiating effect.
Described transformer room arranges transformer, the two side of transformer room arranges blower fan respectively, the exit of blower fan be main air duct go out air port.
Described cabinet is rectangular structure, and the space in cabinet comprises main air duct and device and installs space, and main air duct is stepped and is positioned at the side of cabinet, and another side in cabinet is that space installed by device, and multiple scatterer is distributed in device and installs in space.
When this uses with the electric cabinet of high efficiency and heat radiation labyrinth type air duct, its principle is: freezing air enters insulated chamber from cabinet, enter in corresponding point air channel by each point of air inlet of air duct being arranged in parallel again, by in the process in point air channel, heat exchange is carried out with scatterer, accelerate the heat radiation efficiency of scatterer, thus realize the rapidly and efficiently heat radiation of heat-generating units; The hot blast produced after heat exchange is discharged from the air port (also as the blast inlet of main air duct) that goes out in each point of air channel and is sent in main air duct, finally goes out air port extraction by blower fan from main air duct.
The present invention, relative to prior art, has following useful effect:
This is with in the electric cabinet of high efficiency and heat radiation labyrinth type air duct, by arranging point air channel of main air duct and some parallel connections, and form mazy air channel structure, for each scatterer and heat-generating units configure an independent point air channel, can effectively solve the contradiction between sealing in traditional electrical cabinet, heat radiation, volume and cost, make electricity cabinet compact, cost is lower, possesses good heat dispersion and sealing property simultaneously.
This by arranging the air gathering plate of indent in each point of air channel with in the electric cabinet of high efficiency and heat radiation labyrinth type air duct, after freezing air can be made to enter point air channel, is compressed at air gathering plate place, thus wind speed is accelerated, significantly carried high cooling efficiency.
This is with in the electric cabinet of high efficiency and heat radiation labyrinth type air duct, the blast inlet in each point of air channel and go out air port sealed structure (i.e. rubber ring or isolation ring) is all set, make the device in each point of air channel and cabinet completely isolated, also make the device in cabinet and the external world completely isolated simultaneously, reach the effect of directly externally heat radiation on the one hand, also ensure that the sealing and dustproof performance of cabinet on the other hand.
