Description
Technical field
The utility model relates to electric prospection technical fields, more particularly, to a kind of air switch contact radiator.
Background technique
At present air switch using very extensive, 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 sharply increase so as to cause air switch internal temperature, especially when air switch load is larger, internal temperature
Liter is extremely serious, so that switch contact contact resistance easily be caused to increase, fever aggravation causes contact to burn, or switch is burnt.
Fever also results in electrical component 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 in size, 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 sharply increases, and especially when air switch load is larger, internal temperature rise is extremely serious, so as to cause switch contact 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.
Utility model content
The utility model in order to overcome at least one of the drawbacks of the prior art described above, it is scattered to provide a kind of air switch contact
Hot device is able to solve the problem of existing air switch contact generates heat, and avoids air switch fever tripping or burns out switch.

Including heat absorbing sheet, heat conducting pipe and cooling fin, connected between the heat absorbing sheet and cooling fin by heat conducting pipe, the heat absorption
Piece, heat conducting pipe and cooling fin are provided with insulating oil.
Heat absorbing sheet in this radiator is mounted on the power end and electric power incoming line line ear of air switch, several radiators are simultaneously
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 sharply raised
The heat of air switch contact can quickly be conducted and be distributed in air by topic, guarantee that the heat of air switch contact will not mistake
Height avoids air switch fever tripping or burns out switch, ensure that the stability and 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 mechanical and electric equipment damage, 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.
It 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 dissipation 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, lid is equipped 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 conduct into insulating oil.
Further, the lid is aluminium lid.Since cooling fin is exposed in air, used lid is needed
There is the effect of antirust, therefore selects 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 pipe, and PE material is made with preferable insulating properties and ageing-resistant, and can
Facilitate bending.
Compared with prior art, beneficial effect is:
1, this radiator is able to solve the problem of existing air switch contact fever, and the heat of air switch contact is distributed
Into air, avoids air switch fever tripping or burn out switch；
2, the present apparatus is not necessarily to electrical equipment, non-maintaining after installation without mechanical and electric equipment damage, lossless.It is prolonged
It is durable；
3, the present apparatus is mounted directly for existing air switch without being transformed, non-maintaining after installation, nothing
Loss, it is durable.
