Technical field

The utility model relates to a kind of heat radiation module, particularly reaches the heat radiation module that rapidly heat diffusion is conducted to radiating fin about a kind of pyrotoxin that is arranged at absorption, conduction.

Background technology

Existing heat radiation module comprises a heating radiator and a fan.This heating radiator has a base, this base has two surfaces that are parastate mutually, a wherein surperficial contact heating source of this base, and the peripheral projection on another surface has several radiating fins, make radiating fin central authorities form an accommodation space, but and this accommodation space air feed fan be arranged at wherein.Therefore, the heat that this pyrotoxin produced can be passed to base by contact, conducts to each radiating fin by this base towards diffusion all around again, and then utilizes the circulation of fan priming air-flow to dispel the heat rapidly with auxiliary this radiating fin.

Yet, when heat that pyrotoxin produced by the base central authorities of this heating radiator towards around during the diffusion conduction, because of being subject to the heat-conduction coefficient restriction of the material of this heating radiator own, heat can't be spread very rapidly conduct to each radiating fin, therefore often cause the too high problem of the long-pending heat of this base, particularly when heat that pyrotoxin produced be when concentrating on these base central authorities, then more shape is serious for this long-pending hot too high situation.

The utility model content

Fundamental purpose of the present utility model provides a kind of heat radiation module, with conducting to each radiating fin so that the heat that pyrotoxin produced spreads rapidly.

According to heat radiation module of the present utility model, it comprises a fan, a heating radiator and a heat-conducting piece.This heating radiator has a base, corresponding two sides of this base form first surface and second surface, this first surface periphery projection has several radiating fins, radiating fin central authorities form an accommodation space, this fan is inserted this accommodation space, this second surface has middle section and neighboring area, this middle section is to accommodation space that should first surface, this neighboring area is then to radiating fin that should first surface, this heat-conducting piece comprises at least one heat pipe, this heat pipe is arranged at the second surface of this heating radiator and contacts with pyrotoxin, and this heat pipe extends to the neighboring area by middle section.

Whereby, the utility model utilizes the splendid thermal conduction characteristic of this heat-conducting piece, can be very rapidly with heat conduction that this pyrotoxin produced neighboring area, to reach the effect that auxiliary this base conducts to heat diffusion each radiating fin rapidly to the corresponding radiating fin of this base.

Embodiment

For above-mentioned and other purpose of the present utility model, feature and advantage can be become apparent, preferred embodiment of the present utility model cited below particularly, and conjunction with figs. are described in detail below:

With reference to shown in Figure 1, the heat radiation module of the utility model first embodiment comprises a fan 1, a heating radiator 2 and a heat-conducting piece 3.

Refer again to shown in Fig. 1 to 3, this heating radiator 2 has a base 21, corresponding two sides of this base 21 form first surface 22 and second surface 23, and this first surface 22 and second surface 23 are preferably and are parallel to each other, these first surface 22 peripheral projections have several radiating fins 24, make radiating fin 24 central authorities form an accommodation space 25, and but this accommodation space 25 air feeds fan 1 is inserted, this second surface 23 has a middle section 23A and a neighboring area 23B, this middle section 23A is to accommodation space 25 that should first surface 22, and this neighboring area 23B is then to radiating fin 24 that should first surface 22.

These heat-conducting piece 3 preferable heat pipes (Heat pipe) of selecting for use, it is bent to form by at least one heat pipe 31, can be corresponding to the distribution of shapes of the second surface 23 of this heating radiator 2, and be preferably the S type.Moreover this heat-conducting piece 3 can be selected to be bent to form the S type by a heat pipe 31, also can select by at least two heat pipes 31 crooked also in conjunction with forming the S type.

Shown in 3, when the heat radiation module of the utility model first embodiment is implemented.This fan 1 is arranged in the accommodation space 25 of this heating radiator 2.This heat-conducting piece 3 is arranged at the second surface 23 of this heating radiator 2 and contacts (pyrotoxin shown in the figure is a LED) with a pyrotoxin 4, and this pyrotoxin 4 can utilize spiral shell to establish, be embedded or paste the second surface 23 that any physical bond mode such as fixing is arranged at this heating radiator 2, and this pyrotoxin 4, heat-conducting piece 3 and second surface 23 are fitted tightly.Moreover this heat pipe 31 extends to neighboring area 23B by the second surface 23 middle section 23A of this base 21, and the preferable whole neighboring area 23B that distributes that extends to.

Therefore, the heat that this pyrotoxin 4 is produced can conduct to the neighboring area 23B of this second surface 23 very rapidly by this heat-conducting piece 3, can conduct to each radiating fin 24 towards diffusion all around rapidly with the heat of assisting this base 21.
