Spend direction.In Fig. 1 to Fig. 4 arrow illustrate fluid enter air duct direction and flow out air duct direction.
Heat exchange unit 1 is an overall structure, and refrigerant channel 11 is the runner being formed within；Two 1 phases of heat exchange unit
Adjacent outer surface is used to form air duct.Heat exchange unit 1 realizes the heat sinking function of the refrigerant circulation and fin of refrigerant pipe simultaneously.
One heat exchange unit 1 can be arranged one or more refrigerant channels 11, and the cross-sectional shape of refrigerant channel 11 can be with
For the various shapes such as oval (as shown in Figure 2), round (as shown in Figure 4), polygon.
In order to improve heat transfer effect, the channel that leaks out can be arranged in heat exchange unit 1 near refrigerant channel 11, changed with improving
The heat exchange performance of hot cell 1, flow direction and the refrigerant of these inner fluid passages that leak out flow to parallel.It is possible to further walk
Guide frame is arranged in wind vias inner walls, to increase time of contact of the wind with the vias inner walls that leak out in the channel that leaks out, so that
Heat transfer effect is more preferable.It leaks out there are many cross sectional dimensions in channel, such as the various shapes such as circle, ellipse, polygon.It is each
One or more can be arranged near a refrigerant channel 11 to leak out channel.It leaks out channel if multiple circles, a refrigerant stream
The distance in 11 center of circle of circle center distance refrigerant channel in all channels that leak out is equal near road 11.
Heat exchanger using the above structure can replace refrigerant pipe and fin in existing heat exchanger, using a portion
Part realizes the function of refrigerant pipe and fin simultaneously, therefore can avoid the appearance of refrigerant pipe to fluid flow performance in air duct 12
It influences.
Referring to Fig. 2, heat exchange unit 1 includes by multistage arc at the edge of the opposite sides perpendicular to the cross section of length direction
The curve that line is linked in sequence.
In some embodiments, camber line is selected from one of elliptic arc and circular arc.Referring to Fig. 2, a heat exchange unit 1 is simultaneously
Including curve A, curve B.Curve A, curve B correspond to two surfaces of heat exchange unit 1.For each curve, such as simultaneously including ellipse
Circular arc and circular arc, for example only include elliptic arc or circular arc.In the embodiment of meaning shown in Fig. 2, curve includes mainly elliptic arc, phase
Adjacent both ends elliptic arc rounding off；In the embodiment of meaning shown in Fig. 4, curve includes mainly circular arc, and adjacent both ends circular arc is round and smooth
Transition.
When using oval section, the fluid in air duct 12 contacts more abundant, good effect of heat exchange with the outer wall of heat exchange unit 1.
When using circular arc, the fluid in air duct 12 is substantially tangent with the outer wall of heat exchange unit 1, and heat transfer effect is not so good as to use elliptic arc
It is good.
Referring to Fig. 2, fin 13 is equipped in the junction of adjacent two sections of camber lines.Fin 13 is for increasing fluid and heat exchange structure
Outer wall curved face contact area, improve heat transfer effect.
By taking structure shown in Fig. 2 as an example, increase fin 13, the direction of fin 13 and adjacent elliptical tube at the both ends of oval section
It is tangent and towards leaking out direction.Fin 13 is used to assist leaking out, adjust the direction of fluid, i.e. fin 13 both increases heat-transfer surface
Product, but also air duct 12 is more smoothly, improves the exchange capability of heat of heat exchanger.
Referring to Fig. 2, the wind-guiding direction C and the angle of fluid flow direction D in air duct 12 of fin 13 are acute angle.It needs to illustrate
, the practical flow direction of each position in air duct 12 of fluid is variation and cutting substantially along curve A or curve B
Line direction；On the whole, the flow direction D of fluid is about straight line, and air outlet 122 is flowed to from air inlet 121.
Referring to Fig. 2, it is located on same length direction, heat exchange unit 1 is perpendicular to opposite the two of the cross section of length direction
The projection portion of the camber line of side is alignment.I.e. for the same heat exchange unit 1, according to elliptic arc, curve A's is ellipse
The center of circle of circular arc is overlapped with the center of circle of the elliptic arc of curve B；According to circular arc, then the center of circle of the circular arc of its curve A with it is bent
The center of circle of the circular arc of line B is to overlap.In other words, curve A and curve B are symmetrical relative to the center line of the width direction of shell 2.
Using this structure, heat exchange structure manufacture easier to process, the wind in each air duct 12 is more uniform, and heat transfer effect is more
It is good.
Referring to Fig. 1, heat exchanger further includes shell 2, and heat exchange unit 1 is set in shell 2.Shell 2 is used to support heat exchange unit
1。
Referring to Fig. 1, multiple heat exchange units 1 are arranged side by side in shell 2, the gap between two neighboring heat exchange unit 1 is made
For air duct 12.Gap between 2 inner wall of heat exchange unit 1 and shell at most edge also has fluid to flow through, and is also used as air duct 12
It uses.
Referring to Fig. 1, the multiple heat exchange units 1 being arranged side by side in shell 2 are uniform at the width direction interval of shell 2.In this way
Entire heat exchange structure enters the wind more uniform, good effect of heat exchange.
Referring to Fig. 2, the quantity of heat exchange unit 1 is two or more, the protrusion of the camber line of two neighboring heat exchange unit 1
Part is staggeredly.Referring to Fig. 2, is illustrated with two heat exchange units 1 of Far Left, be located at the convex of first, left side heat exchange unit 1
It is staggeredly to rise with the protrusion positioned at second heat exchange unit 1 in left side, so that the air duct 12 between the two heat exchange units 1
It is arc, is easy to air flowing.
The staggered layout of elliptical tube, forms corrugated air duct 12 inside shell 2, since the curvature of elliptical tube becomes
Change the Curvature varying less than pipe, so the Curvature varying for avoiding air duct 12 excessive, reduces windage.
Referring to Fig. 2, each air duct 12 is configured in the face for being parallel to each cross section of fluid flow direction in air duct 12
Product is roughly equal.I.e. in addition to the place that fin 13 is arranged, sectional area may be more a little bit smaller, remaining cross-sectional area is equal.Ginseng
See that Fig. 2, the i.e. area equation of cross section E, F, the air-flow in such air duct 12 are uniform, good effect of heat exchange.
In some embodiments, the integrated extrusion forming of heat exchange unit 1.For example be molded using Extrusion Process of Aluminum Alloy Profile, using aluminium profiles
The mode of material extrusion molding realizes the processing of heat exchanger, can endless in the longitudinal direction, realize Three-dimension process to two dimension plus
The depression of order of work, simplifies processing technology, reduces processing cost.
In some embodiments, heat exchange unit 1 and the common integrated extrusion forming of shell 2.Referring to Fig. 1, each section in Fig. 1
All it is integrated extrusion forming.
In some embodiments, the ratio of the major diameter of elliptic arc and minor axis is 1.5-2.The ellipse arc of this structure at
Air duct 12 is more conducive to air-flow flowing.
If the cross section of refrigerant channel 11 is also ellipse, the ratio of major diameter and minor axis is 1.5-2.The shape of refrigerant channel 11
Shape is similar with the shape that two sections of elliptic arcs surround, but size dimension is different.
In some embodiments, the major diameter of elliptic arc is parallel to fluid flow direction in air duct 12.Signified fluid herein
Flow direction is parallel to short transverse shown in FIG. 1.The major diameter of elliptic arc is parallel to the short transverse of shell 2.Elliptic arc this
Kind arrangement form so that 12 curvature of air duct will not be excessive, and wind flowing in air duct 12 is more smooth, and heat transfer effect is more preferable.
