Pipe.
Detailed description of the invention
The technical scheme provided the present invention below in conjunction with Fig. 1～Fig. 3 is explained in more detail
State.
The present embodiment is as a example by heat exchanger uses on air-conditioning.The blower fan of air-conditioning is approximately at housing
The middle part of short transverse, heat exchanger is normally at below blower fan, and the distance the most remote air quantity of blower fan is the least.
Upstream, downstream are with the landing direction of condensed water as reference, and in the present embodiment, the first header 1 exists
The upstream of the second header 3.
Seeing Fig. 1 and Fig. 2, the embodiment of the present invention one provides a kind of heat exchanger, including the first collection
Flow tube the 1, second header 3 and heat exchanger tube 4.The upstream extremity of heat exchanger tube 4 and the first header
1 connection, the downstream of heat exchanger tube 4 connects with the second header 3；Wherein, adjacent two are changed
Heat pipe 4 is smaller than the spacing in downstream end at upstream extremity.
Spacing at upstream extremity refers to adjacent two heat exchanger tubes 4 spacing near the first header 1,
The spacing of downstream end refers to adjacent two heat exchanger tubes 4 spacing near the second header 3.
Specifically, along being from upstream to the direction in downstream, the spacing of adjacent two heat exchanger tubes 4 is
Gradual change.Adjacent two heat exchanger tubes 4 spacing at upstream extremity is minimum, between downstream end
Away from maximum.Following manner specifically can be used to realize:
Seeing Fig. 1, in the present embodiment, heat exchanger tube 4 is straight tube, along being from upstream to downstream
Direction, the spacing of adjacent two heat exchanger tubes 4 is gradual change.Adjacent two heat exchanger tubes 4 are basic in " eight "
Font is arranged, and is from upstream to downstream span and becomes larger.
In the present embodiment first header 1 and the structure of second header 3 is described below.
In the present embodiment, the structure of each heat exchanger tube 4 is identical, i.e. each cross section of heat exchanger tube 4
Structure is identical, is all oblate.
Alternatively, in the present embodiment, the first header 1 and the second header 3 are all annular,
And first the girth of header 1 than all length of the second header 3.
Annular can be annular, or oval ring, or rectangular-shaped annular etc..
No matter the first header 1 be annular or straight tube referred to hereafter, the second header 3
For annular or straight tube referred to hereafter, the first header 1 is designed with several and heat exchanger tube
First through holes of 4 connections, the second header 3 is designed with several connect with heat exchanger tube 4 the
Two through holes.First through hole and the second through hole one_to_one corresponding and quantity are equal, every pair of first through hole,
A heat exchanger tube 4 it is provided with between second through hole.Each first through hole can spaced set, each second
Through hole can spaced set.
Further, the straight of the center of the first header 1 and the center of the second header 3 is connected
Line is perpendicular to the plane at the first header 1 place.Using this structure, the structure of heat exchanger is
Upper end is big, lower end is little, more firm during placement, is more easy to install.
The set-up mode of fin 2 is described below.It is provided with along changing between adjacent two heat exchanger tubes 4
The fin 2 of heat pipe 4 length bearing of trend；At the upstream extremity of fin 2 more intensive than downstream end.
The heat exchange efficiency of heat exchanger is relevant with air quantity and heat exchange area, heat exchange efficiency=air quantity/heat exchange
Area.Air quantity is big, the little then heat exchange efficiency of heat exchange area high.Close first header of fin 2
One end of 1 is upstream extremity, and fin 2 is downstream near one end of the second header 3.Fin 2
Use said structure, in the region that bottom air quantity is little, fin 2 sparse；On top, air quantity is big
Region, fin 2 is intensive, and the heat exchange efficiency of whole heat exchanger is more uniform, and is conducive to
Discharge condensed water and reduce air flow resistance.
Seeing Fig. 1, the fin 2 between adjacent two heat exchanger tubes 4 is laciniation；
Along being from upstream to the direction in downstream, wave height h of fin 2 is progressively longer or stairstepping is elongated.
Due to the spacing being smaller than downstream end at the upstream extremity of adjacent two heat exchanger tubes 4, accordingly
Ground, along being from upstream to the direction in downstream, the wave height of fin 2 is progressively longer or ladder deformation
Long, with the structure of corresponding heat exchanger tube 4 so that fin 2 is fully contacted with heat exchanger tube 4, thus
Ensure heat exchange efficiency.
See the technical side of Fig. 3, the technical scheme of the embodiment of the present invention two and above-described embodiment one
Case has a following difference: along being from upstream to the direction in downstream, between adjacent two heat exchanger tubes 4
Away from being steps change.
Heat exchanger tube 4 can be bend pipe, along being from upstream to the direction in downstream, and adjacent two heat exchanger tubes
The spacing of 4 is steps change, as shown in Figure 3.On first header 1 adjacent two
Spacing between one through hole is little, spacing between adjacent two the second through holes on the second header 3
Greatly, heat exchanger tube 4 is bend pipe, and upstream extremity and the first header 1 connect, downstream and the second collection
Flow tube 3 connects, at the stairstepping sudden change of heat exchanger tube 4, between adjacent two heat exchanger tubes 4
Spacing also occurs stairstepping to change.It should be noted that Fig. 3 illustrates that each heat exchanger tube 4
Have one sudden change ladder situation, actual can also be arranged as required to two or more
Sudden change ladder.
In the present embodiment, the first header 1 and the second header 3 are all straight tube, and the first collection
The length of flow tube 1 is shorter than the length of the second header 3.
First header the 1, second header 3, heat exchanger tube 4 substantially form trapezium structure.First
Header 1 is provided with several the first through hole connected with heat exchanger tube 4, and the second header 3 sets
There is several the second through hole connected with heat exchanger tube 4.First through hole and the second through hole one_to_one corresponding and
Quantity is equal, is provided with a heat exchanger tube 4 between every pair of the first through hole, the second through hole.
Technique scheme, owing to being smaller than downstream at the upstream extremity of adjacent two heat exchanger tubes
Spacing at end, during condensed water is discharged, more down migration, between heat exchanger tube between
Away from the biggest, condensed water does not haves water blocking phenomenon so that air can circulate easily, will not
Because condensed water occurs that water blocking reduces air quantity, it is ensured that system reliability and heat exchange efficiency.
