In the above embodiments, since refrigerant (containing fluorinated refrigerant) or water can be used to exchange heat for the heating heat exchanger
Medium keeps heat transfer effect more preferable to improve heat exchange efficiency, and the utility model finds the spacing of heat exchanger components by research and changes
The height of thermal part is an important factor for influencing heat transfer effect, and the spacing of heat exchanger components is smaller, and heat exchanger components are more intensive, heat exchanging part
The heat exchange area of part side is bigger, to a certain degree under, heat exchange also can accordingly increase；But heat exchanger components spacing is too small, is unfavorable for sky
The free convection of gas is flowed, and then influences heat-transfer effect, while too small heat exchanger components spacing can also make the weight of entire heating piece
Amount increases, and cost increases.Another important influence factor is the height of heat exchanger components, and heat exchanger components height is higher, heat exchange
Component heat exchange area is bigger, and in a certain range, heat exchange amount is bigger；But heat exchanger components continue growing, heat exchanger components end is (close
Air side) temperature compared to substrate root temperature it is also lower, cause the heat transfer temperature difference of heat exchanger components end and air smaller, instead
And heat transfer efficiency is relatively low.Moreover, when for example described heat exchanger components 3 are fin 32, the change of 3 size of the heat exchanger components will increase
The size of production difficulty and production cost, heat exchanger components 3 is related to heat exchanger channels 31.Accordingly, it is considered to above-mentioned reason, by grinding
The parameter value for studying carefully to obtain the heat exchanger components 3 can be as follows:
The direction that about 3 heat exchanger components extend is width direction, and the direction that the heat exchanger components 3 or so extend is length

As described in Figure 3, the wherein upper header in two headers 1 is additionally provided with partition board 8, another makes for flowing back
Cryogen.It is the first chamber 12 separated and that the header 1 for being connected with inlet tube 6 and outlet 7, which includes with the partition board 8,
Two chambers 13, the first chamber 12 and the second chamber 13 are separately connected different heat exchanger tubes 2, and different flows is flowed to form two.It is described
Inlet tube 6 is connect with first chamber 12, and the outlet 7 is connect with second chamber 13.First chamber 12 connects described
The number of heat exchanger tube 2 is more than the number that second chamber 13 connects the heat exchanger tube 2, and the reason of setting in this way is because for example existing
For the utility model heat exchanger as condenser in use, the refrigerant of first pass is gaseous refrigerant, density is small, and flow velocity is high,
Therefore in order to reduce resistance, first pass needs the heat exchanger tube being more arranged side by side 2, and refrigerant is dissipated by first pass
After heat, gaseous state becomes liquid, and density increases, in order to ensure exchange capability of heat, opposite first pass, flat tube number in second procedure
Quantity needs few.
For example, the partition board 8 divides heat exchanger tube 2 for first part heat exchanger tube 2a and second part heat exchanger tube 2b.And its
In, first chamber 12 is connect with inlet tube 6, high temperature heat transferring medium of the afflux from compressor is used for, then by heat transferring medium
It is conveyed to the first part heat exchanger tube 2a (flow direction is as shown by the arrows in Figure 3) being connect with first chamber 12, first part heat exchange
Pipe 2a is mainly used for and air heat exchange.Second part heat exchanger tube 2b is connect by second chamber 13 with outlet 7, and described
Two chambers 12 are for the heat transferring medium (flow direction and arrow in Fig. 3 are reversed) after afflux heat exchange, and then heat transferring medium is changed by second part
Heat pipe 2b is exported to outlet 7.
For example, by taking 15 heat exchanger tubes 2 of grafting on header 1 as an example, the partition board 8 is arranged at the 10th and the 11st
Between root heat exchanger tube 2, to form two flows, (number for the heat exchanger tube 2 being connect with the first chamber 12 is 10, as the first heat exchange
The number of flow, the heat exchanger tube 2 being connect with the second chamber 13 is 5, as the second heat exchange process).The refrigerant of heat transfer medium by into
Mouth pipe 6 enters the first chamber 12, then is circulated to 10 heat exchanger tubes 2 of first part heat exchanger tube 2a to the right, then passes through the heat exchanger right side
The header 1 at end is circulated to 5 heat exchanger tubes 2 of second part heat exchanger tube 2b.Most of the header 1 through heat exchanger left end afterwards
Two chambers 13 are circulated to outlet 7.More than two flows can certainly be set.Heat transferring medium uses when containing fluorinated refrigerant, because
It is gaseous state into the refrigerant in heat exchanger tube 2, density is small, and flow velocity is high, needs multiple flows, to reduce flow velocity, reduce resistance.It is cold
For matchmaker after heat dissipation, gaseous refrigerant gradually becomes liquid refrigerant, and density is big, flow velocity is small, needs smaller flow.In order to
The convection transfer rate for improving refrigerant side, can suitably reduce flow number.Fig. 5 is the part of heat exchanger tube in an exemplary embodiment
Structural schematic diagram；Fig. 6 is the structural schematic diagram that heat exchanger tube is connect with header in an exemplary embodiment.Such as Fig. 5 and Fig. 6 institutes
Show, the latter end 22 that the heat exchanger tube 2 includes main paragraph 21, connect with the header 1, and the connection main paragraph 21 and institute
State the commutation section 23 of latter end 22.Wherein, the main paragraph 21 is main heat exchange part, is contacted with heat exchanger components 3 that length is longer than
The commutation section 23 and latter end 22.The commutation section 23 makes to be in a predetermined angle between the latter end 32 and the main paragraph 31,
The predetermined angle can be 90 °, naturally it is also possible to be slightly less than 90 °.Such as it can be when manufacturing the main paragraph 21, using torsion
Mode by the main paragraph 21 a part torsion certain angle, with formed the latter end 22 and commutation section 23.
As shown in Figure 5, it is flat to be located at two dislocation for the large contact (heat-transfer area) of the latter end 22 and the main paragraph 21
On face, the main paragraph 21 is contacted with large contact with the heat exchanger components 3, and the occupancy that the latter end 22 then can be less
The length of the header 1.Correspondingly, the header 1 is equipped with the mounting groove 11 of latter end 22 described in grafting, the mounting groove
11 length direction is axially vertical with the header 1.In this way, under equal length header 1, which can insert
Connect more heat exchanger tubes 2.As shown in figure 5, the mounting groove 11 cross at along its length on the header 1 and with the collection
