As it is shown in figure 1, on the substrate 10, by multiple fin 20,20 of regulation sheet number ... the groups of fins 27 being arranged in parallel is provided with multiple (being 4 in the present embodiment).Groups of fins 27 is configured to two row two row along the X-direction shown in Fig. 1 and Y-direction the two direction.

The orientation of the orientation (normal direction of fin 20) of one groups of fins 27 and another groups of fins 27 of (in the present embodiment, being included in the adjacent situation of X-direction and the most adjacent situation both of these case) adjacent thereto intersects (in the present embodiment for orthogonal).

The substrate 10 of said structure and fin 20 are formed with utilizing the metal split formed by the raw material that the heat conductivities such as copper, copper alloy, aluminum or aluminum alloy are outstanding, combined by filleting or the known joint method such as soldering (solder brazing) is fixed and is formed.Air-through holes 24, groove portion 12, notch 25, pipe through hole 26 are after substrate 10 and fin 20 being engaged, and are formed by machining.Additionally, the forming method of substrate 10 and fin 20 is not limited thereto, it is possible to formed by additive method.

Radiator 1 according to said structure, fin 20 has inclination face 21 and air-through holes 24, thus the air between adjacent fin 20,20 easily flows.Hereinafter, with reference to Fig. 3 and Fig. 4, illustrate with along the flowing towards corresponding air between fin 20,20.

As shown in Figure 3, substrate 10 is positioned at bottom, at fin 20,20 in the case of longitudinal direction (Z-direction) erects, due to the heat radiation from base end side planar portions 22a, in gap between adjacent base end side planar portions 22a, 22a, the heated and air that rises is in the part without air-through holes 24, the direction of flowing changes (solid arrow with reference in Fig. 3) along tilting face 21, and in the part having air-through holes 24, moved (dotted arrow in reference to Fig. 3) to adjacent gap by air-through holes 24.In gap (without the part of air-through holes 24) between level face 23,23, due to the heat radiation from level face 23, air is heated, thus rises stream and produce further, and flow velocity is accelerated.In the part having air-through holes 24, owing to being pulled by the upper up-flow of both sides (level face 23,23), air rises.In the inclination face 21 of upside, the air risen is in the part without air-through holes 24, the direction of flowing changes (solid arrow with reference in Fig. 3) along tilting face 21, and in the part having air-through holes 24, moved (dotted arrow in reference to Fig. 3) to adjacent gap by air-through holes 24.In gap between front planar portions 22b, 22b, due to the heat radiation from front planar portions 22b, air is heated, thus rises stream and produce further.Finally, heated air discharges from the upper end of front planar portions 22b to outside.

As it has been described above, be at fin 20,20 between the fin 20,20 of the radiator 1 of the present embodiment of the state erected to longitudinal direction, the direction of the flowing of air changes, and is not susceptible to be detained.And then, due to air also to horizontal mobility, thus it being prone to occur the air stream in gap, the mobile quantitative change of the air in radiator 1 is big.Thus, the heat energy distributed can be effectively to the flows outside of radiator 1, thus compared with being simple flat situation with fin, heat dispersion improves.And then, at air along when tilting face 21 flowing, air mixes, thus the air being unheated contacts with the surface tilting face 21 successively.Thus, radiating efficiency improves.

As shown in Figure 4, substrate 10 be positioned at sidepiece and fin 20,20 extend to laterally (direction (X-direction or Y-direction) orthogonal with Z-direction) and in the case of being in the state of couching, due to from base end side planar portions 22a or the heat radiation of front planar portions 22b, in gap between adjacent fin 20,20, heated air rises in gap, rise along tilting face 21, and moved to the gap of upside by air-through holes 24.In tilting the part of face 21 and air-through holes 24, air flows upwards, thus air about is raised stream and is pulled, and flow to inclination face 21 and air-through holes 24.The air flowed in the gap of upside air-through holes 24 from the upper side flows to more top.The air flowed the most upward is to the outside releasing of radiator 1.

As it has been described above, between the fin 20,20 of the radiator 1 being in present embodiment to the state laterally couched at fin 20,20, air flows upward from air-through holes 24.Tilt face 21 with air-through holes 24 near, air be raised stream pulled and also to horizontal mobility, thus be prone to generation air stream, the mobile quantitative change of the air in radiator 1 is big.Thus, the heat energy distributed can be effectively to the flows outside of radiator 1, thus compared with being simple flat situation with fin, heat dispersion improves.From the part that inclination face 21 and air-through holes 24 leave, heated air is released to outside from the circumference of fin 20.That is, according to the radiator 1 of present embodiment, no matter being in which kind of attitude, compared with conventional radiator, heat dispersion is all improved.

In addition, when level face 23 is in than base end side planar portions 22a and front planar portions 22b more on the lower, even if fin 20 is in the state couched, in air-through holes 24 part, also up-flow can be produced, the air of the surrounding of air-through holes 24 be raised stream pulled and to horizontal mobility, thus be prone to generation air stream.

The most in the present embodiment, air-through holes 24 is to be formed in the way of level face 23 and another inclination face 21 from least one inclination face 21, thus at fin 20 in the case of longitudinal direction erects, face 21 is tilted across level face 23 and another inclination face 21 from one, the circulation of air between adjacent gap can occur, thus be prone to produce air stream.

And then, in the present embodiment, the orientation of one groups of fins 27 and the orientation of another groups of fins 27 adjacent thereto intersect, thus in the case of substrate 10 is positioned at sidepiece and fin 20 is in the attitude (along the attitude of X/Y plane) to horizontal expansion, is in longitudinal (along XZ plane or YZ plane) groups of fins 27 and coexists with being in horizontal (along the attitude (state of Fig. 4) of X/Y plane) groups of fins 27.Thus, at least one of groups of fins 27, fin 20 is in longitudinal state, thus air between fin 20,20 is heated and is prone to flow upward.Therefore, be in horizontal radiator with all of fin compared with, heat dispersion improve.

Additionally, by heat pipe 30 end being connected to the substrate-side end of fin 20, and another end of heat pipe 30 is connected to the leading section of fin 20, accordingly, can use heat pipe 30 that the heat of the substrate-side end of fin 20 is transferred to leading section, thus can further improve heat dispersion.

And then, the radiator 1 of present embodiment makes an effort at the vpg connection of fin 20, and heat dispersion improves, because of without cooling fan.Thus, it is not necessary to the power of radiator fan, noise will not also be produced.It addition, for this radiator 1, even when exposed in wind and rain, also there is no problem, thus is used as in outside.

Fin 20a according to this structure, tilting face 21, in the part without air-through holes 24a, the direction of flowing changes (with reference to the solid arrow of Fig. 5 A) along tilting face 21, and in the part having air-through holes 24a, move (with reference to the dotted arrow of Fig. 5 A) to adjacent gap by air-through holes 24a.In gap between level face 23,23, due to the heat radiation from level face 23, air is heated, thus rises stream and occur further, and flow velocity is accelerated.Especially in fin 20a, there is no air-through holes 24a at level face 23, thus up-flow can be produced further, thus flow velocity can be further speeded up.Thus, it is possible to increase the flowing of the air in gap, thus heat dispersion improve.

In the radiator 1 of above-mentioned embodiment, the incline direction of two inclination faces 21,21 of fin 20 is contrary, and length is identical, but is not limited to this shape.For the fin 20b of other variation, as shown in Figure 5A, two tilt face 21,21 be in identical direction (side the most forward, more to the right side of Fig. 5 A and Fig. 5 B towards).In this variation, in the same manner as Aforesaid deformation example, air-through holes 24a is to be formed at two in the way of each inclination face 21.Additionally, air-through holes can also be formed in the way of level face 23 and another inclination face 21 to tilt face 21 from one.

Fin 20b by means of this structure, also in the same manner as fin 20a, in tilting face 21, in the part without air-through holes 24a, the direction of flowing changes (with reference to the solid arrow of Fig. 5 B) along tilting face 21, and in the part having air-through holes 24a, move (with reference to the reference dotted arrow of Fig. 5 B) to adjacent gap by air-through holes 24a.In gap between level face 23,23, due to the heat radiation from level face 23, air is heated, thus can produce up-flow further, and flow velocity is accelerated.Therefore, in fin 20b, it is possible to obtain the action effect being equal to the fin 20a of Fig. 5 A.
