On passage flat tube, micro-channel heat exchanger heat exchange property is influenced, therefore just need to micro-channel heat exchanger to solve defrost water problems
Optimize.
The scheme that the existing patent of Publication No. CN 201225792Y uses is directly to be tiltedly mounted on micro-channel flat
On micro-channel heat exchanger, defrosting water can be preferably set smoothly to be flowed down from micro-channel flat, but micro-channel flat tilts
The flow resistance increase of internal flow afterwards, and reduce heat exchange efficiency.
Therefore, how designing can just be such that defrosting water is not accumulated in micro-channel flat, lift changing for micro-channel heat exchanger
Hot property.
Utility model content
In order to solve drawbacks described above existing in the prior art, prevent defrosting water from gathering micro- the utility model proposes a kind of
Passage flat tube and micro-channel heat exchanger.
The technical solution adopted in the utility model is a kind of micro-channel flat, including a plurality of microchannel ducts, described micro-
Passage flat tube is bent to form two groups of inclination heat-transfer areas, and the microchannel duct of identical quantity is included in two groups of inclined planes.
Preferably, the angle formed after micro-channel flat bending is greater than or equal to 120 ° and less than 180 °.
Preferably, micro-channel flat is made of aluminum alloy materials.
The utility model also proposed one kind using micro-channel heat exchanger made of above-mentioned micro-channel flat, further include parallel
Two headers set, complex root micro-channel flat are arranged on two collection evenly and at intervals along the axial direction of header successively
Between flow tube, the microchannel duct of the micro-channel flat is connected with the header, the micro-channel flat be horizontally disposed with and
Its heat-transfer area is downwardly inclined.
Preferably, header and the joint face of micro-channel flat are plane.
Further, header is square tube.
Preferably, it is equipped with fin between two adjacent micro-channel flats.
Compared with prior art, micro-channel flat is designed to the micro- form tilted down in both sides by the utility model, and is
The micro-channel flat of this form of cooperation, is designed to square tube, easy to fixation between the two by header；This both sides it is micro- to
Under inclined micro-channel flat defrosting water can be promoted to be flowed down from micro-channel flat, and then exclude to accumulate in change on header
White water, while the inclined design in this both sides can strengthen the level of disruption of fluid, enhanced heat exchange, improve the heat-exchange performance of heat exchanger
Energy.
Brief description of the drawings
The utility model is described in detail with reference to embodiment and attached drawing, wherein：
Fig. 1 is the schematic perspective view of the utility model micro-channel flat；
Fig. 2 is the schematic cross-section of the utility model micro-channel flat；
Fig. 3 is the schematic perspective view of the utility model header；
Fig. 4 is the utility model micro-channel flat and the assembling schematic diagram of header.
Embodiment
Micro-channel heat exchanger is during the use as outer machine heat exchanger, when outer machine carries out defrost, due to microchannel
Flat tube is horizontal plane, is blown away so the defrosting water above micro-channel flat is mainly the wind produced using outer wind turbine, still
Still have part defrosting water not to be blown away, so as to accumulate in micro-channel flat, prevent defrosting water clean from excluding, reduce
The heat exchange property of heat exchanger.
As shown in Figure 1, 2, one embodiment of the utility model provides the micro-channel flat after a kind of improvement, micro-channel flat
1 is in the strip of flat, is made of aluminum alloy materials.Be separated out between the inside of micro-channel flat 1 it is a plurality of be arranged side by side it is micro-
Passage duct 101 is used to shunt, and each microchannel duct 101 is square and cross-sectional area is identical, it is arranged side by side accumulates most below
Big both sides are the heat-transfer area of micro-channel flat 1, and refrigerant exchanges heat by microchannel duct 101 with air.Micro-channel flat 1
Be parallel to each other two-by-two four inclined heat-transfer areas are bent to form as boundary using medial axis, identical quantity is included in two groups of inclined planes
Microchannel duct 101, it is in triangular shape to make micro-channel flat 1, than in the prior art micro-channel flat inside stream during single sided taper
The flow resistance of body reduces half, enables a fluid to fully exchange heat, and the angle α that micro-channel flat 1 is formed after bending is big
In or equal to 120 ° and be optimized scope less than 180 °.
As shown in Figure 2,3, 4, another embodiment of the utility model provides a kind of using made of above-mentioned micro-channel flat 1
Micro-channel heat exchanger, including：More micro-channel flats 1 and two headers 2 for being separately positioned on 1 both ends of micro-channel flat, two
Root header 2 is parallel to each other, and is connected with the microchannel duct 101 of micro-channel flat 1.The header 2 at both ends is square pipe
Road, it is refrigerant circulation passage 201 that pipeline is interior.The joint face of square pipe is conducive to the micro-channel flat 1 in triangular shape for plane
It is preferably fixed, make the stable structure of micro-channel heat exchanger.The opposite face for two headers 2 being arranged in parallel is equipped with mounting hole,
Mounting hole is used for the both ends for connecting fixed micro-channel flat 1.Refrigerant inside the header 2 of 1 one end of micro-channel flat is by making
The microchannel duct 101 of micro-channel flat 1 reaches the header of the other end with air heat-exchange, the edge from top to bottom of micro-channel flat 1
The axial direction uniform intervals for the circulation of header 2 are horizontally arranged between header 2, improve heat exchange area and efficiency, and micro-
Heat transfer of the passage flat tube 1 with bending angle side is face-down, angle is divided equally by vertical curve, reduces 1 inside stream of micro-channel flat
The flow resistance of body.During the micro-channel heat exchanger of the present embodiment is used as outer machine heat exchanger, in the wind that outer wind turbine produces
When can not blow away defrosting water completely, in the micro-channel flat 1 of triangular shape defrosting water can be made to be flowed down along both sides bevel edge, can not gathered
