Description
Technical field
The present invention relates to electric fittings technical field, and in particular to can automatic heat radiation distribution box.
Background technology
Distribution box is for reasonable distribution electric energy, and there is the convenient switching action to circuit, distribution box higher safety to prevent
Protect grade, can intuitively display circuit conducting state.Distribution box application field is extensive, covers industry, agricultural, traffic, section
Skill, environmental protection and people's lives etc..
Electrical instrumentation component working in distribution box can produce heat, raise the temperature in distribution box；Existing distribution
Case is typically that radiator fan is set in distribution box, is passed the heat of thermal source by the heat emission hole on distribution box by radiator fan
Export is gone.But the size of heat emission hole is fixed, after the temperature in distribution box raises, the heat dissipation capacity of heat emission hole is constant to be caused to dissipate
Not in time, thermal effect is poor for heat.
The content of the invention
The invention is intended to provide it is a kind of temperature rise after increase heat emission hole can automatic heat radiation distribution box.
In this programme can automatic heat radiation distribution box, including casing and the case lid that is hinged on casing, in the casing
Provided with fan, the heat emission hole of multiple protrusion case lid surfaces, each heat emission hole side are provided with the case lid at thermal source
Be installed with fixed plate, the opposite side of each heat emission hole be hinged with can automatically reset variation plate, the variation plate is towards dissipating
Electromagnet is fixed with hot hole inwall side, air bag is fixed with the inwall of the heat emission hole, the air bag direction changes plate one
It is fixed with iron block on the end of side, the iron block is in air bag expanded by heating into the range of the magnetic journey of electromagnet；
The heat emission hole inwall of the fixed plate side is provided with infrared transmitting tube, the heat emission hole for changing plate side
Inwall is provided with sliding part, and the sliding part top is provided with the infrared receiving tube that can be sheltered from by variation plate, the infrared receiver
Manage the infrared light for receiving infrared transmitting tube；
Also include controller, the infrared receiving tube sends current signal when being blocked to controller, and the controller is used for
Fan is controlled to improve rotating speed according to current signal.
The working principle and beneficial effect of this programme is, during electrical instrumentation component working in distribution box, fan is by electricity
Heat caused by instruments and meters part is transmitted to outside distribution box by heat emission hole, with the work of electrical instrumentation part, in distribution box
Temperature gradually rise, the temperature at heat emission hole also gradually rises, temperature rise the air in air bag is gradually expanded, air bag by
Gradually swelling, air bag, which swells, promotes iron block to plate side is changed, until iron block enters in the range of the magnetic journey of electromagnet, iron block and electricity
Attraction is produced between magnet, is be hinged due to changing plate, the attraction between iron block and electromagnet is adsorbed onto air bag by plate is changed
Place, increases the discharge area of heat emission hole, makes the air output of heat emission hole bigger, improves radiating efficiency.
When variation plate is not attracted power and is adsorbed onto at air bag, infrared receiving tube receives the infrared light of infrared transmitting tube
Line, it is normal that controller receives infrared receiving tube current value；When variation plate, which is adsorbed to, shelters from infrared receiving tube at air bag,
The current value that controller receives infrared receiving tube reduces, and controller control rotation speed of the fan, improves the rotating speed of fan, accelerates to dissipate
Heat.
Secure the air-bag on the inwall of heat emission hole, can prevent that air bag is drawn onto variation plate when iron block and attracting electromagnet
On, ensure to change and got off in plate by suction.
After the temperature in distribution box recovers normal, air bag temperature also declines, and air bag recovers original size, makes iron block gradual
Moved to outside the magnetic journey scope of electromagnet, reduce the attraction between iron block and electromagnet, at the same change plate by with attraction
The automatically reset power of opposite direction, sheet reset is changed to initial position.
Change plate be adsorbed to increase heat emission hole at air bag while, controlling the rotating speed of fan increases, and allows in distribution box
Heat quickly conducted, the heat emission hole of increase can allow more heats to be transferred out distribution box with air, imitate radiating
Fruit is more preferable.
Further, the hinged place for changing plate is combined with rotating shaft, is equipped with torsion spring in the rotating shaft, and the one of the torsion spring
Individual straight reverse arm is fixedly connected with changing plate, and another straight reverse arm of the torsion spring is fixed on the inwall of heat emission hole.
When variation plate is adsorbed onto at air bag by the attraction between iron block and electromagnet, torsion spring is produced elasticity by torsion
Deformation, and after the attraction between iron block and electromagnet reduces, torsion spring, which recovers elastic deformation, makes variation sheet reset, in distribution box
Temperature reduce after automatically reset, ensure to increase heat emission hole after temperature raises, accelerate radiating, without human intervention, using more
It is convenient.
Further, the air bag is elliposoidal when being filled with air, and the iron block is fixed on air bag towards variation plate side
Point on.
The air bag of elliposoidal can allow two tip expansions of air bag to extend, make iron block to electromagnet side when air expands
Mobile distance is bigger, is further ensured that iron block can enter in the range of the magnetic journey of electromagnet.
Further, the end that the air bag fixes iron block has retractility.
The end for only allowing air bag to fix iron block has a retractility, and air expansion makes the retractility of air bag bigger, allow iron block to
The magnetic journey scope displacement of electromagnet is bigger, ensures that iron block can enter the magnetic journey scope of electromagnet.
Further, stomata is offered on the case lid of the variation plate side, the sliding part is that can cover stomata
Sliding block, the sliding block are slidably fitted on the be hinged inwall for changing plate side of heat emission hole, and the air bag is located at sliding block with changing plate
Between, the sliding block is supported downwards when electromagnet mutually adsorbs with iron block by variation plate, is offered on the sliding block and is changing plate
The through hole to be alignd when being supported downwards with stomata.
When variation plate is adsorbed at air bag, changes plate and support sliding block downwards, make on the through hole and case lid on sliding block
Stomata aligns to form the passage of radiating, while heat emission hole is increased, increases the pore quantity of radiating, distribution box can quickly be dissipated
Heat, improve radiating efficiency.
Further, the infrared receiving tube is arranged on sliding block, and the infrared receiving tube is supported downwards in sliding block by variation plate
When be occluded.
While variation plate is adsorbed at air bag, changes plate and cover infrared receiving tube, reduce controller and receive
Electric current, make controller control fan improve rotating speed, increase heat emission hole and increase radiating pore quantity, accelerate radiating, carry
High cooling efficiency, make radiating effect more preferable.
Further, supporting plate is fixed with the case lid, stage clip is connected with the supporting plate, the stage clip is connected to cunning
On block.
When sliding block is supported downwards by variation plate, sliding block, which moves down, applies pressure to stage clip, and stage clip produces elastic deformation, when
When changing sheet reset, the pressure that stage clip is subject to cancels, and stage clip recovers elastic deformation and resets sliding block, convenient in next distribution box
Increase the hole of radiating after temperature rise.
