Description

A kind of graphene heat abstractor

Technical field

The utility model is related to a kind of heat abstractor, and in particular to a kind of graphene heat abstractor of air heating machine.

Background technology

Heat generating ceramic piece, heating resistance wire are conventional heater elements, in the prior art, using heat generating ceramic piece, heating Resistance wire warms up warmer as the wind of heater element and mostly heated by the way of setting impeller to dry in side (i.e. wind is warmed up), is Heater element radiating is helped, also heat abstractor can be equipped with for heater element, existing heat abstractor is made up of some metals Fin is arranged at intervals what is formed, and fin is in contact with the heater element.

Existing heat abstractor can accelerate the rate of heat dispation of heater element to a certain extent, but preferable not enough, Reason is as follows：

1st, fin is made up of metal material, good heat conduction effect, but outwards heat loss through radiation effect is less desirable；

2nd, the wind that impeller is produced simply unidirectionally is moved from the lateral opposite side of heat abstractor one, and air is contacted not with heat abstractor Fully.

Utility model content

The purpose of this utility model is to provide a kind of graphene heat abstractor.

To realize above-mentioned utility model purpose, the utility model is adopted the following technical scheme that：

Have gap between a kind of graphene heat abstractor, including some fins, the adjacent fin, the fin by Made by sheet metal, a lateral edges of the fin away from impeller are provided with flange, the outer surface of the fin and are equipped with stone Black alkene thermal dispersant coatings.

As the further improved technical scheme of the utility model, the fin is made up of copper or aluminium material.

It is of the present utility model to have technical effect that relative to prior art：

The utility model is provided with graphene thermal dispersant coatings, the resistance to elevated temperatures of graphene thermal dispersant coatings on fin outer surface It is outstanding, can normally it be used at a temperature of 25-350 degrees Celsius, heat transference efficiency is high and there is the heat loss through radiation of far infrared to imitate Really, good heat dissipation effect, sets flange to form air return disturbance, air connects with heat abstractor in the lateral edges of air-out one of fin Touch more fully, preferably heater element can be helped to radiate.

Brief description of the drawings

Fig. 1 is a kind of structural representation of graphene heat abstractor and heater element in the utility model embodiment；

Fig. 2 is the structural representation of fin；

Fig. 3 be in Fig. 2 A-A to cross section structure diagram.

Embodiment

The utility model is described in detail below with reference to embodiment shown in the drawings.But these embodiment party Formula is not intended to limit the utility model, structure that one of ordinary skill in the art is made according to these embodiments, method or Conversion functionally is all contained in protection domain of the present utility model.

A kind of embodiment of the present utility model presented below：

Fig. 1 is referred to 3, a kind of graphene heat abstractor, including some fins 1 has between the adjacent fin 1 Gap, the fin 1 is as made by sheet metal, and a lateral edges of the fin 1 away from impeller are provided with flange 11, the fin Graphene thermal dispersant coatings 3 are equipped with 1 outer surface.

Formed it should be noted that graphene thermal dispersant coatings 3 are sprayed on the outer surface of fin 1 by graphene slurry, it is resistance to High-temperature behavior is outstanding, normally can use (radiating) at a temperature of 25-350 degrees Celsius, and the heat loss through radiation with far infrared Effect.

A lateral edges (air-out side) of the fin 1 away from impeller are provided with flange 11, and raised flange 11 stops that air-flow is formed The backflow disturbance of air, air contacts more abundant with heat abstractor, shown in arrow is air-flow direction in Fig. 3.Need Even if still having gap it is noted that being provided between flange 11, adjacent fin 1.

It is shown in Figure 1, the utility model in use, heater element 2 is set through fin 1, and is contacted with fin 1, The heat transfer that heater element 2 is produced passes to graphene thermal dispersant coatings 3 to fin 1, then by fin 1, is finally dissipated by graphene Hot coating 3 passes to air.

Heater element 2 can be heat generating ceramic piece or heating resistance wire.

Further, the fin 1 is made up of copper or aluminium material.

The utility model is provided with graphene thermal dispersant coatings, the heat-resisting quantity of graphene thermal dispersant coatings 3 on the outer surface of fin 1 Can be outstanding, can normally it be used at a temperature of 25-350 degrees Celsius, heat transference efficiency is high and has the heat loss through radiation of far infrared Effect, good heat dissipation effect sets flange 11 to form air return disturbance, air and radiating in the lateral edges of air-out one of fin 1 Device contact is more abundant, can preferably help heater element 2 to radiate.

Finally it should be noted that：Embodiment of above is only limited to illustrate the technical solution of the utility model, rather than to it System；Although the utility model is described in detail with reference to aforementioned embodiments, one of ordinary skill in the art should Understand：It can still modify to the technical scheme described in foregoing each embodiment, or special to which part technology Levy carry out equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from each reality of the utility model Apply the spirit and scope of mode technical scheme.
