Abstract
The utility model discloses a kind of new micro-channel heat exchanger, including working medium entrances collector tube, several fins being stacked, arc flow distribution plate, sender property outlet collector tube, several flat tubes are pierced by the fin, the arrival end of several flat tubes is plugged on one end of the arc flow distribution plate, tap hole is provided on the other end of the arc flow distribution plate, the port of export of several flat tubes is plugged in the collector plate of sender property outlet collector tube；One end of the working medium entrances collector tube is working medium entrances, and the other end of the collector tube is connected with the one end of arc flow distribution plate with tap hole, is sealed between the arc flow distribution plate and working medium entrances collector tube with sealed piece.Working medium enters working medium entrances collector tube from working medium entrances, after the flow distribution plate shunting of arc, then the working medium after throttling is allowed to enter the corresponding flat tube.Due to the driving of working medium big pressure drop at arc flow distribution plate so that distribution of the working medium between multiple flat tubes is easily uniform.
Description
Technical field
The utility model is related to air-cooler cooling fin technical fields, and in particular to a kind of new micro-channel heat exchanger.
Background technology
Among refrigerating field, working medium after the throttle throttling, after becoming the relatively low liquid of pressure, is then fed into evaporation
Device exchanges heat in the microchannel in evaporator, but working medium when into each microchannel because cryogen is unevenly distributed, cause
Performance drastically declines when micro-channel heat exchanger is as evaporator operation.In this regard, common practices is in the micro- logical of micro-channel heat exchanger
Porous or slot is opened above road on installation distributor, each hole or slot correspond to multiple flat tubes and carry out refrigerant distribution.Due to flat tube with it is flat
Distribution between pipe it is uneven and it is each it is flat in each microchannel between distribution that may be present it is uneven, using single hole or
It is difficult prediction that the distribution of refrigerant that single slot corresponds to multiple flat tube distribution, which is, and micro-channel evaporator is caused to need to adjust repeatedly when developing
Examination, to reach desired distribution effects.
Utility model content
The purpose of this utility model is to solve the distribution unevenness of working medium between flat tube and flat tube in the prior art, provides one kind
New micro-channel heat exchanger.
In order to achieve the above object, the utility model uses following technical scheme：
A kind of new micro-channel heat exchanger, including working medium entrances collector tube, several fins being stacked, arc shunting
Plate, sender property outlet collector tube are pierced by several flat tubes in the fin, and several flat tubes are plugged on the one of the arc flow distribution plate
It holds, tap hole is provided on the other end of the arc flow distribution plate；One end of the collector tube be working medium entrances, the collector tube
The one end of the other end and arc flow distribution plate with tap hole be connected, sealed between the arc flow distribution plate and collector tube with sealed piece
Firmly.
Further, it is not provided with tap hole on the arc flow distribution plate immediately below the working medium entrances.
Further, the tap hole set on the arc flow distribution plate immediately below the working medium entrances gradually increases around.
Further, the tap hole is one kind in oval or circle.
Further, the sealed piece is made of one or is arranged separately in the liquid collecting pipe end with the arc flow distribution plate
In the block in portion.
Further, the working medium entrances are located at the centre position of collector tube.
The beneficial effects of the invention are as follows：Working medium is entered from working medium entrances in collector tube, is shunted by the flow distribution plate of arc
Afterwards, then the working medium after throttling is allowed to enter the corresponding flat tube.Due to the driving of working medium big pressure drop at arc flow distribution plate,
So that distribution of the refrigerant between multiple flat tubes is easily uniform.

Specific embodiment
With reference to specific embodiments and the drawings, the utility model is described in further detail, elaborates in the following description
More details are in order to fully understand the utility model, but the utility model obviously can be different from what this was described with a variety of
Other manner is implemented, and those skilled in the art can be in the case of without prejudice to the utility model connotation according to practical application feelings
Condition makees similar popularization, deduces, therefore should not limit the scope of protection of the utility model with the content of this specific embodiment.
As shown in Figures 1 to 5, a kind of new micro-channel heat exchanger, by working medium entrances collector tube, arc flow distribution plate, flat tube,
Fin, sender property outlet collector tube are formed, and one end of working medium entrances collector tube is working medium entrances 1, working medium entrances collector tube 2 it is another
It holds and is connected with the one end of arc flow distribution plate 3 with tap hole 4, with envelope between the arc flow distribution plate 3 and working medium entrances collector tube 2
Mouth part seals, and the sealed piece is made of one or is arranged separately in the working medium entrances collector tube 2 with the arc flow distribution plate 3
In the block of end.Several flat tubes 5 are pierced by the fin 6, the entrance of several flat tubes 5 is plugged on the arc flow distribution plate
3 one end is provided with tap hole 4 on the other end of the arc flow distribution plate 3, and the working medium that institute's working medium entrances are stated in collector tube 2 enters
Mouth 1 is located at the centre position of collector tube 2.The outlet of several flat tubes 5 is plugged in the collector plate 8 of sender property outlet collector tube
In spliced eye 9.The tap hole 4 set on arc flow distribution plate 3 immediately below the working medium entrances 1 gradually increase around, can incite somebody to action
Tap hole 4 is arranged to one kind in ellipse or circle, because the arc flow distribution plate 3 at immediately below working medium entrances 1 is subject to working medium
Impact force is larger, and surrounding impact force is smaller, and such setting of tap hole makes working medium easily be distributed equally.Enter in the working medium
Tap hole 4 is not provided on arc flow distribution plate 3 immediately below mouthful 1, because entering in collector tube 2 power pressure very from working medium entrances 1
Greatly, if setting tap hole 4 on the arc flow distribution plate 3 of underface, working medium is easily flowed into from the tap hole 4 immediately below working medium entrances 1
Flat tube 5, it is not easy to working medium be distributed equally.
