Description
Technical field
The present invention relates to refrigeration technology field, the micro-channel heat exchangers such as evaporator, condenser and its micro-channel heat exchanger group
Part.
Background technique
Micro-channel heat exchanger is that a kind of efficient new type heat exchanger is used in refrigeration, field of radiating.The body of the heat exchanger
Product is smaller, and lighter in weight, structure height is compact, can be avoided potential corrosion, is easily recycled.
Have several microscale channels in the flat tube of micro-channel heat exchanger, the equivalent diameter in channel between 10-1000 μm,
Flat tube both ends connect with header, and header is for distributing and collecting refrigerant.
Microscale channel thinned liquid hot-fluid boundary layer obtain sufficiently heat exchange, obtain great convection transfer rate and
The high compactness of volume, achieves good results in terms of heat transfer effect.
But this micro-channel heat exchanger exists simultaneously some shortcoming and deficiency, mainly：
First, microchannel two phase refrigerant is difficult to evenly distribute, and leads to mass flow discrepancy of the refrigerant in micro-channel flat, causes
Heat transfer effect is poor.
Second, micro-channel heat exchanger monnolithic case in a limited space in do not meet the demand of truth.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide it is a kind of reasonable in design,
Make the uniform flow distribution in flat pipes of micro-channel heat exchangers with the bending distribution mode of parallel flat tube using part flow arrangement, together
When global shape be closer to the needs of truth.
The present invention solves the problem above-mentioned by the following technical programs：
The micro-channel heat exchanger, including upper header, lower header, part flow arrangement and more micro-channel flats and flat
The heat exchange fin being distributed on pipe.The part flow arrangement is the flat tube of inner hollow, starting point and is connected with upper and lower header,
More micro-channel flats are corresponded with the branch of part flow arrangement respectively to connect, and the micro-channel flat being arranged mutually parallel presents curved
Split cloth.
The normal direction that the flat pipes of micro-channel heat exchangers is distributed presented plane is consistent with header lengths direction.
The part flow arrangement shape of micro-channel heat exchanger of the present invention is hollow flat tube structure similar with micro-channel flat
At shape can well be docked with micro-channel flat and header.
The lower header of micro-channel heat exchanger of the present invention is connected with part flow arrangement, flat to that will flow into microchannel
Refrigerant in pipe is evenly distributed.
The upper header of micro-channel heat exchanger of the present invention is connected with part flow arrangement, the refrigerant that confluence is completed
In feeding in header.
The part flow arrangement of micro-channel heat exchanger of the present invention is connected with flat tube, will evenly distribute the refrigerant of completion
It is sent into the microchannel of each flat tube, while the refrigerant that micro-channel flat flows out being converged.
The micro-channel flat of micro-channel heat exchanger of the present invention takes the mode for the bending distribution that is parallel to each other, Neng Gougen
The shape for specifically bending heat exchange area produced by distribution mode is determined according to actual conditions, is convenient for practical application.
