Description

The heat abstractor of uniform arrangement heat pipe evaporation ends

Technical field

The utility model refers to be arranged with on a kind of heat conducting base the heat abstractor of heat pipe especially about a kind of heat abstractor.

Background technology

Because heat pipe (Heat pipe) has plurality of advantages such as high capacity of heat transmission, in light weight, simple in structure, not power consumption and life-span be long, a large amount of heats that produced when therefore being highly suitable for transmitting electronic product such as CPU running.

General heat pipe structure has evaporation ends and condensation end, when heat pipe is applied to the heat abstractor of electronic product, the evaporation ends of heat pipe is connected as thermal conductance with the heating electronic building brick, the condensation end of heat pipe opposite side is equipped with two or more radiating fins, high capacity of heat transmission by heat pipe, the heating heat that electronic building brick produced is passed on each radiating fin by heat pipe, with heat extraction one by one, cooling, simultaneously, for the heat of being hoarded between each radiating fin, also can cooperate radiator fan, reach better heat radiating effect so that can apace heat be expelled.

For the heating heat that electronic building brick produced can be passed on each radiating fin more quickly, can carry out the transmission of heat with the heat pipe more than two or two usually.Please join Figure 1A and Figure 1B, be equipped with the heat pipe 2 more than two or two on the heat conducting base 1, utilize the evaporation ends of heat pipe 2 to amplexiform on heating electronic building brick 4 surfaces, the condensation end cross-under at heat pipe 2 opposite sides has radiating fin 3 again, the heat that is produced during with 4 runnings of diversion heating electronic building brick; Yet, because each heat pipe 2 is center and the concentrated area is arranged on the heat conducting base 1 with heat conducting base 1 central authorities, therefore when the heat pipe more than two or two 2 amplexiforms at heating electronic building brick 4, the evaporation ends of heat pipe 2 is concentrated the central authorities that are laid in heating electronic building brick 4 surfaces, so, the heat at the 4a place, corner of heating electronic building brick 4 will be unfavorable for deriving, and produce localized hyperthermia on the electronic building brick 4 that easily causes generating heat; In addition, when heat conducted on the heat conducting base 1, heat easily concentrated on heat conducting base 1 central authorities and fails uniform corner 1a to heat conducting base 1, makes the heat conducting base 1 of tool heat sinking function fail to give a full play of its radiating effect, therefore, can't be in time and derive the heat of heating electronic building brick 4 apace.

Shown in Fig. 2 A and Fig. 2 B, heat abstractor for the indirect heat conduction of another kind, be embedded with the heat pipe 2 more than two or two on the surface of heat conducting base 1, utilization is with heat conducting base 1 another surperficial smooth contact heating electronic building brick 4 surfaces, make the heat that produced of heating electronic building brick 4 be passed to heat conducting base 1 earlier, again by heat conducting base 1 with the evaporation ends of heat transferred to heat pipe 2, last, be passed to the condensation end of its opposite side by heat pipe 2, relend by radiating fin 3 the heat diversion; Yet, because each heat pipe 2 is center and the concentrated area is embedded on the heat conducting base 1 with heat conducting base 1 central authorities, heating electronic building brick 4 is passed to the evaporation ends absorption of the heat of 1 of heat conducting base by the heat pipe 2 that is laid in heat conducting base 1 central authorities, heat at 1a place, the corner of heat conducting base 1, be provided with heat pipe 2 because of arranging above it, so 1a place, the corner heat of heat conducting base 1 will be difficult for deriving, the heat that the unfavorable electronic building brick 4 that will generate heat evenly, is apace produced conducts on the radiating fin 3.

In sum, known to be the center with heat conducting base 1 central authorities concentrate on arrangement mode on the heat conducting base 1 with heat pipe 2, and the heat that the unfavorable electronic building brick 4 that will generate heat evenly, is apace produced conducts on heat conducting base 1 and the radiating fin 3.
