Abstract
The utility model is suitable for technical field of heat dissipation.The utility model discloses a kind of active heat sink, the utility model improved to reach by heat radiating fin structure and improves while air channel fluid damping ensures actual air volume before not affecting, also provide a kind of to pass through fin air channel, as structures such as grooves, carry out surface-treated method to reduce real fluid damping, and optimize the heat exchanging process of fin surface and fluid simultaneously, thus make same volume radiator obtain higher heat-sinking capability.
Description
Technical field
The utility model relates to electronic devices and components, household electrical appliance and heating and ventilating equipment technical field of heat dissipation, refers more particularly to the components and parts heat dissipation problem that power is larger.
Background technology
Existing active heat sink is generally made up of fin and fan, efficiently radiates heat surface area is increased by the structure (equally having groove structure) designing the structures such as groove on a heat sink or utilize heat pipe to be welded with fin, then air and fin surface is made to carry out forced-convection heat transfer, to play the effect of enhance heat by fan.
Current techniques mainly considers the best fit of fin efficiently radiates heat area and fan duty from structural point.Different heat radiating fin structures can impact the actual air volume of identical characteristics fan, and air quantity is also the key factor of the radiating efficiency affecting radiator, when fan duty is determined, due to necessary actual air volume will be ensured, fin is limited many when doing structure optimization, affects the lifting of radiator integral heat-sinking capability.In addition, the primary surface state of fin trench interiors is unfavorable for aerodynamic characteristics, also affects the heat-sinking capability of radiator to a certain extent.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of to be had air dynamic behaviour and has coating compared with high heat-transfer performance simultaneously, for covering radiator or heat dissipation wind channel surface, heat is passed to while heat radiation top layer and fluid contact carry out heat exchange in time and reduces the resistance of fluid, when fan duty one timing, fan can be effectively reduced in the actual static pressure in this air channel, thus improve actual air volume.And heat transfer boundary layer characteristic can be optimized, improve radiator heat-dissipation ability further.
The utility model provides a kind of active heat sink, comprises fan and fin, it is characterized in that: also comprise the surface-treated layer be located on fin.
Say further, described surface-treated layer at least comprises the carbon granule of nanometer or Subnano-class.
Say further, described surface-treated layer also comprises ceramic particle.
Say further, described surface treatment layer thickness is 20-100um.
The utility model radiator coatings applications scheme comprises, and uses above-mentioned coating material by spraying coating process at common radiator or the surface-treated layer forming 20-100um thickness specially for heat spreader structures fin (runner) surface that this coating characteristic is optimised.Its main effect model is that the coating comprising nanometer or Subnano-class carbon granule and ceramic particle has special shiny surface and low surface tension, effectively can improve fluid and radiator surface of solids behavior of boundary layer and the energy (heat) strengthening air molecule and the radiator surface of solids exchanges, play the effect of enhance heat, thus improve radiator heat-dissipation performance.Particularly when having long-range runner or complicated runner, effect is more obvious.

Fig. 4 is the view of the utility model embodiment 2.
Below in conjunction with embodiment, and with reference to accompanying drawing, the realization of the utility model object, functional characteristics and advantage are described further.
Embodiment
In order to make to want the object of utility model, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model provides that a kind of it comprises fan 1 for directly contacting the radiator of electric heating device heat away, the fin 2 be connected with fan, and the surface-treated layer 3 arranged on fin 2.
Specifically, surface-treated layer 3 is provided with at the surface uniform of fin 2, described surface-treated layer 3 at least comprises carbon granule and the ceramic particle of nanometer or Subnano-class, its main effect model utilizes the coating comprising nanometer or Subnano-class carbon granule and ceramic particle to have special shiny surface and low surface tension, effectively can improve fluid and radiator surface of solids behavior of boundary layer and strengthen the exchange heat of air molecule and the radiator surface of solids, play the effect of enhance heat, thus improve radiator heat-dissipation performance.Particularly when having long-range runner or complicated runner, effect is more obvious.
The radiator using the present invention to design production, compared with radiator that is identical or that know each other structure, when (meeting general sector application condition) under the same conditions and dispel the heat to identical thermal source, can improve cooling extent.Measured data is as following table:
Note 1.: represent the thermal power that thermal source is different
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or equivalent replacement is carried out to wherein portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
