In the case that size on W is less big, can be used only include single stacked body structure, alternatively referred to as single row configuration, single heap
The detailed structure view of heat-dissipating pipe 20 in stack is presented in Fig. 5.
Heat-dissipating pipe 20 is the form of aluminium alloy flat tube, passes through hot gas method for processing forming or those skilled in that art
Known any other method appropriate is made.Generally, heat-dissipating pipe 20 is by perpendicular to the transverse direction T, phase each other
Extend in the generally horizontal plane that mutually vertical longitudinal direction L and lateral W is limited.Each heat-dissipating pipe 20 limits coolant flow
Warp, the coolant channel 25 (Fig. 5) of both ends open, battery 30 to be cooled are clamped at adjacent two of T-phase in transverse direction and dissipate
Between heat pipe 20, the cross section of battery 30 to be cooled is located at the roughly vertical plane limited by longitudinal direction L and transverse direction T
In, and battery to be cooled 30 corresponds to all heat-dissipating pipe stacked bodies on lateral W in the development length on lateral W
Overall width.Each heat-dissipating pipe 20 be fixed at opposite first end 21 and second end 29 in the longitudinal directionl supporting member 40 or
It is supported by supporting member 40.

Direction.Although in the drawings, longitudinal direction L and lateral W is shown as extending and transverse direction T in generally horizontal plane
It is shown as extending in roughly vertical face, it is to be understood that the orientation with power battery cooling device 100 is different, transverse direction
T, the direction of longitudinal direction L and lateral W also can be different.So direction term herein with respect to rather than absolutely.
As being clearly shown in Fig. 5, L, heat-dissipating pipe 20 include intermediate radiator section 22 along the longitudinal direction, are located at intermediate dissipate
Longitudinal two sides of hot arc 22 and the contraction section 24 being connected with intermediate radiator section 22, and the longitudinal direction L positioned at heat-dissipating pipe 20
On two opposite ends at expanding reach 26.Expanding reach 26 is located at one opposite with intermediate radiator section 22 of contraction section 24
Side and respectively with corresponding contraction section 24 be connected.

20b, i.e., along the sectional view of line A-A and B-B in Fig. 5.
In intermediate radiator section 22, heat-dissipating pipe 20 limits elongated cross section 20a.Elongated cross section 20a include along
The first size that transverse direction T extends and the second size that laterally direction W extends, the second size are greater than first size.I.e.
Heat-dissipating pipe 20 limits the elongated shape cross section in the plane limited by transverse direction T and lateral W.Such as adding
The factors such as work manufacture consider that the elongated shape cross section is the rectangular cross section of rounding.
Still referring to FIG. 5, on lateral W, contraction section 24 from one end that it is connected with intermediate heat exchanging segment 22 towards its with
The connected other end of expanding reach 26 is decreased to expanding reach 26 in side from first width D 1 of the intermediate heat exchanging segment 22 on lateral W

, as known by those skilled in the art, 25 size of coolant channel of each heat-dissipating pipe 20 is smaller, and heat exchange property is better.
In heat-dissipating pipe 20 in the case where the thickness on transverse direction T is constant, the variation of width will affect heat dissipation effect.It is radiating simultaneously
The width of pipe 20, i.e. intermediate heat exchanging segment 22 are in the case where the width D 1 on lateral W is bigger, the cross section of heat-dissipating pipe 20

As above-mentioned, each heat-dissipating pipe 20 is made of intermediate heat exchanging segment 22, contraction section 24 and expanding reach 26, this makes, referring again to
Fig. 4 A, the spacing d2 on lateral W between the intermediate heat exchanging segment 22 of adjacent heat-dissipating pipe 20 are less than the expansion of heat-dissipating pipe 20
Spacing d1 between section 26.Spacing d2 between intermediate heat exchanging segment 22 is the heat dissipation " blind area " on the surface of cylindrical battery 30, and d2 is got over
It is small more advantageous to heat dissipation effect, and the spacing d1 between expanding reach 26 corresponds to the gap between the slot 42 of supporting member 40,
D1 is bigger, and process gap requirement when processing slot 42 is lower, processes simpler.Preferably, the gap between slot 42 is greater than
5mm.If in the case where meeting the diagram gap between slot 42, heat-dissipating pipe 20 stretches design using cross-section, that is,
It says, d1 is big as d2, this will be unfavorable for heat dissipation and the protecting effect of battery.
