Portion's heat-conducting medium 4 first can be exchanged heat with the first Thermal Performance of Micro Channels pipe 311, be carried out again with the second Thermal Performance of Micro Channels pipe 321 afterwards
Heat exchange.
It is micro- that first Thermal Performance of Micro Channels pipe 311 includes first with the set-up mode set before and after the second Thermal Performance of Micro Channels pipe 321
Channel for heat exchange pipe 311 before and after the second Thermal Performance of Micro Channels pipe 321 be arrangeding in parallel, and the first Thermal Performance of Micro Channels pipe 311 and second
Such as the flow direction of the axis direction of Thermal Performance of Micro Channels pipe 321 and outside heat-conducting medium 4 in 90 ° into identical angle
Angle.Alternatively, the first Thermal Performance of Micro Channels pipe 311 is led with the plane common to the second Thermal Performance of Micro Channels pipe 321 parallel to outside
The flow direction of thermal medium 4.Certainly, the axis of the first Thermal Performance of Micro Channels pipe 311 and the second Thermal Performance of Micro Channels pipe 321 can also be into
Certain less angle, is not necessarily intended to be substantially parallel setting.
As evaporator in use, the refrigerant in the first Thermal Performance of Micro Channels pipe 311 and the second Thermal Performance of Micro Channels pipe 321 is deposited
Endothermic process is vaporized at one, to reach the purpose of refrigeration.First Thermal Performance of Micro Channels pipe 311 have first entrance section 311a and
First outlet section 311b, in the first Thermal Performance of Micro Channels pipe 311, the refrigerant in the first refrigerating circuit 1 is by first entrance section
311a flows to first outlet section 311b.
Second Thermal Performance of Micro Channels pipe 321 has second entrance section 321a and second outlet section 321b, is changed in the second microchannel
In heat pipe 321, the refrigerant in the second refrigerating circuit 2 flows to second outlet section 321b by second entrance section 321a.
In the flow process of refrigerant, more liquid is respectively provided with first entrance section 311a and second entrance section 321a
Refrigerant, liquid refrigerant is vaporized when being flowed in the first Thermal Performance of Micro Channels pipe 311 and the second Thermal Performance of Micro Channels pipe 321
Endothermic process, gaseous state is changed into when flowing in first outlet section 311b and second outlet section 321b.Because gaseous refrigerant can not enter
Promoting the circulation of qi endothermic process, so first outlet section 311b and second outlet section 321b refrigerating capacity can be weaker than first entrance section
311a and second entrance section 321a.
Therefore, in order that the EAT of the second Thermal Performance of Micro Channels pipe 321 becomes uniform, at one of the present utility model
In embodiment, on the flow path of outside heat-conducting medium 4, first entrance section 311a is located at second outlet section 321b front side,

Flow path on, first outlet section 311b be located at second entrance section 321a front side, outside heat-conducting medium 4 can successively with
First outlet section 311b and second entrance section 321a contacts.
Specifically, outside heat-conducting medium 4 is divided into tri- parts of 4a, 4b, 4c along the first Thermal Performance of Micro Channels pipe 311.Outside
Portion heat-conducting medium 4a can be first stronger with refrigerating capacity first entrance section 311a carry out contact heat-exchanging, it is then weaker with refrigerating capacity
Second outlet section 321b carry out contact heat-exchanging.Outside heat-conducting medium 4c can be first weaker with refrigerating capacity first outlet section
311b carries out contact heat-exchanging, then the second entrance section 321a stronger with refrigerating capacity carries out contact heat-exchanging.Outside heat-conducting medium 4b
It is then that the middle part of the successively first Thermal Performance of Micro Channels pipe 311 suitable with refrigerating capacity and the second Thermal Performance of Micro Channels pipe 321 is connect
Touch heat exchange.
So, after outside heat-conducting medium 4a, 4b, 4c are cooled down by the first Thermal Performance of Micro Channels pipe 311, with different temperatures, one
As for, outside heat-conducting medium 4a temperature is less than outside heat-conducting medium 4b temperature, and outside heat-conducting medium 4b temperature is less than
Outside heat-conducting medium 4c temperature.For the relatively low outside heat-conducting medium 4a of temperature, the cold that it is additionally required is less, therefore suitable
Contact heat-exchanging is proceeded to it in the second outlet section 321b for using refrigerating capacity weaker.For the higher outside heat conduction of temperature
Medium 4c, the cold that it is additionally required is more, is consequently adapted to continue it using the stronger second entrance section 321a of refrigerating capacity
Carry out contact heat-exchanging.Thus, the uniformity of the EAT of the second Thermal Performance of Micro Channels pipe 321 is improved, so as to improve
The heat exchange efficiency of dual system micro-channel heat exchanger.
It should be noted that above-described embodiment is described using dual system micro-channel heat exchanger as evaporator.
In the utility model, dual system micro-channel heat exchanger can also be practical as condenser, to be carried out continuously to outside heat-conducting medium 4
Heating.Because the condensation process of refrigerant includes the phase transition process from gaseous state to liquid, changed so as to will also result in the first microchannel
There is the phenomenon along pipeline exchange capability of heat skewness in condensation process in the Thermal Performance of Micro Channels pipe 321 of heat pipe 311 and second, so that
Cause EAT not uniform enough.The utility model provide dual system micro-channel heat exchanger as condenser in use,
