Description
Technical field
The utility model relates to resistive technologies fields, and in particular to a kind of heat sink resistance.
Background technique
The circuit of high-voltage great-current is generally located in spacious environment, and the circuit needs to be arranged corresponding current-limiting resistance,
It is easy to burn to prevent circuit.The current-limiting resistance of the prior art is set as lesser volume to save space as much as possible, this undoubtedly can
Reduce the heat dissipation performance of resistance itself；In addition, current-limiting resistance is long-term exposed in spacious environment, for a long time by exposure and rainwater
The influence of corrosion is easy to cause current-limiting resistance to be oxidized and damage.
Utility model content
For the prior art there are above-mentioned technical problem, the utility model provides a kind of anti-oxidation, high temperature resistant, heat dissipation performance
Good and surface insulation resistance.
To achieve the above object, the utility model the following technical schemes are provided:
A kind of heat sink resistance, including resistor body are provided, coat insulating radiation coating, institute on the surface of the resistor body
State insulating radiation coating not exclusively coat the resistor body so that resistor body there are the positions connected for conducting wire.
Wherein, the insulating radiation coating that the insulating radiation coating is made of graphene and resin.
Wherein, the resistor body is resistor disc.
Wherein, resistor disc punching in such a way that metal rushes grid forms.
Wherein, the insulating radiation coating with a thickness of 1~2mm.
Wherein, the insulating radiation coating is located at the middle part of the resistor disc, and the insulating radiation coating is not coated by institute
State two opposed ends of resistor disc.
Wherein, two opposed ends of the resistor disc extend outwardly to form convex edge respectively, offer on the convex edge
Connecting hole, the connecting hole are connected for conducting wire
The utility model has the beneficial effects that
The utility model is coated with one layer of insulating radiation coating on the surface of resistor body, which can coat guarantor
Resistor body is protected, to prevent the air in resistor body and environment from oxidation occurs and prevent resistance by raindrop erosion, improves electricity
The service life of resistance body；And the radiating insulating coating can effectively improve the rate of heat dispation of resistor body, substantially improve resistor body
Heat dissipation performance.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of heat sink resistance of the utility model.
Appended drawing reference:
Resistor body 1；Insulating radiation coating 2.
Specific embodiment
The utility model is described in detail below in conjunction with specific embodiments and drawings.
Embodiment.
A kind of heat sink resistance of the present embodiment, shown in Fig. 1, the surface of resistor body 1 coats insulating radiation coating 2, and insulation dissipates
The insulating radiation coating 2 that hot coating 2 is made of graphene and resin, graphene have preferable heating conduction, convenient for heat dissipation, and
Resin then has preferable insulation performance.Insulating radiation coating 2 not exclusively coating resistor body 1 so that resistor body 1 there are for conducting wire
The position of connection.Wherein, resistor body 1 is resistor disc, and resistor disc can preferably adapt to high-voltage great-current, which passes through metal
The mode punching for rushing grid forms.Coated in the insulating radiation coating 2 on resistor disc with a thickness of 1~2mm, in order to avoid insulating radiation
The thickness of coating 2 is blocked up and wastes raw material and insulating radiation coating 2 is blocked up and resistor disc is hindered to radiate.Insulating radiation coating 2
It is not coated by two opposed ends of the resistor disc and is located at the middle part of the resistor disc, so that there are the positions connected for conducting wire
It sets, and two opposed ends of resistor disc have opened up connecting hole 3 for conducting wire connection.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
