Description
Technical field
The present invention relates to electric prospection technical fields, more particularly, to a kind of air switch contact radiator.
Background technology
The use of air switch is very extensive at present, and either in civilian or industrial and mining enterprises, usage amount is very huge,
But current air switch is because its is closed, and inside air switch, the contact especially switched is the main portions of fever, the heat of generation
Amount can not scatter, and drastically be increased so as to cause air switch internal temperature, especially when air switch load is larger, internal temperature
Liter is extremely serious, and to easily cause switch contact contact resistance to increase, fever aggravation causes contact to burn, or switchs and burn.
Fever also results in electrical equipment operation irregularity and trip phenomenon, has seriously affected the electricity consumption needs of normal production and living.
Air switch fever is inevitable under high current.Current each air switch manufacturing enterprise is all to reduce air
Switch fever is in effort.Such as utilize the conductive better contact of new technology development & production.Air switch contact is core as you know
The heart.However new technology, new product can only reduce calorific value, not be avoided that fever but.However air switch is small, close because of its
Close, plastics its heat-sinking capability that shell is insulation it is very poor, cause the heat generated to be not easy to scatter, so as to cause air switch inside
Temperature drastically increases, and especially when air switch load is larger, internal temperature rise is extremely serious, is contacted so as to cause switch contact
Resistance increases, fever aggravation, leads to that contact is burnt or switch insulation is impaired.Trip phenomenon is caused, normal production has been seriously affected
The electricity consumption of life needs.The fever of air switch contact cannot scatter outward.Cause air switch to generate heat, eventually leads to fever tripping
Or burn out switch.
Invention content
The present invention is at least one defect overcome described in the above-mentioned prior art, provides a kind of air switch contact heat dissipation
Device can solve the problems, such as existing air switch contact fever, avoid air switch fever tripping or burn out switch.

Row is mounted on power end.Heat absorbing sheet absorbs heat caused by air switch contact, and conducts heat in insulating oil, leads to
It crosses insulating oil to transfer heat on cooling fin, finally distributes the heat of air switch contact in air by cooling fin,
It solves heat caused by existing air switch to be not easy to scatter, be asked so as to cause air switch internal temperature is drastically raised
The heat of air switch contact can quickly be conducted and be distributed in air, ensure that the heat of air switch contact will not mistake by topic
Height avoids air switch fever tripping or burns out switch, ensure that stability and the safety of power supply.This radiator is utilized
The characteristic of cold and hot liquids convection current carries out cold cycling, is not necessarily to electrical equipment, without the damage of machinery and electric equipment, for existing
Air switch is mounted directly without being transformed, non-maintaining after installation, lossless, durable.It is selected in this radiator
With insulating oil, the insulation performance that insulating oil is utilized will be electrically separated, not charged on cooling fin to reach safe, easy for installation.
Further, further include thermally conductive sheet, the thermally conductive sheet is connect with heat absorbing sheet, and the thermally conductive sheet is immersed in insulation
In oil.Thermally conductive sheet can play the role of conductive heat sink piece heat, increase the contact area with insulating oil by thermally conductive sheet, can
Quickly heat is conducted by insulating oil.
Further, the cooling fin is equipped with several radiating fins.After cooling fin absorbs heat, convection current is used
Form heat produced is fallen, heat dissipation area is mainly determined by the size of the surface area of radiating fin during heat loss through convection
, surface area is bigger, and heat dissipation effect is better；Surface area is smaller, and heat dissipation effect is poorer.Therefore multiple radiating fins are provided with,
The surface area effectively to radiate is bigger, therefore perfect heat-dissipating, increases and radiates with cross-ventilation, finally by the heat of switch contact
It distributes in air.
Further, it is equipped with lid at the top of the cooling fin.Lid is used to cover the end of cooling fin, avoids insulating oil
It leaks out.
Further, the thermally conductive sheet is copper sheet.The thermal conductivity of copper sheet is good, and accordingly acting as thermally conductive sheet can be by heat absorbing sheet
On heat quickly conduction in insulating oil.
Further, the lid is aluminium lid.Since cooling fin is exposed in air, used lid needs
There is the effect of antirust, therefore select aluminium lid, and aluminium lid quality is small, and excessive load, and aluminum material will not be caused to cooling fin
Similarly there is preferable thermal conductivity, can quickly distribute heat.
Further, the heat conducting pipe is PE pipes, and PE materials are made with preferable insulating properties and ageing-resistant, and can
Facilitate bending.
Compared with prior art, advantageous effect is：
1, this radiator can solve the problems, such as existing air switch contact fever, and the heat of air switch contact is distributed to sky
In gas, avoids air switch fever tripping or burn out switch；
2, the present apparatus is not necessarily to electrical equipment, non-maintaining after installation without the damage of machinery and electric equipment, lossless.It is durable；
3, the present apparatus is mounted directly for existing air switch without being transformed, non-maintaining after installation, lossless
Consumption is durable.
