Technical field
The utility model is related to field of air conditioning, in particular to a kind of header and micro-channel heat exchanger, air conditioner.
Background technology
With the development of air-conditioning heat exchanger technology, micro-channel heat exchanger due to its heat transfer efficiency height, small volume, it is lightweight, Cooling medium charging amount is few, compact conformation the advantages of, as industry high-performance heat exchanger study and pay close attention to focus.Microchannel is changed simultaneously Hot device is used as outer machine heat exchanger, and in outer machine defrost, defrosting water is flowed on chassis by header, and defrosting water is in header Upper accumulation, causes ponding, reduces defrost efficiency.
Utility model content
The utility model, which is aimed to provide, a kind of prevents header and micro-channel heat exchanger, the air conditioner of ponding.
The utility model provides and is provided with draining knot on a kind of header, the surface that header is connected with micro-channel tubes Structure.
Further, discharge structure is draining inclined-plane.
Further, draining inclined-plane is inverted " v " draining inclined-plane.
Further, the cross section of header is in pentagon.
Further, header is triangular in shape close to the side of micro-channel tubes, and side of the header away from micro-channel tubes is in Rectangle.
Further, the mounting groove coordinated with micro-channel tubes is offered on draining inclined-plane.
The utility model additionally provides a kind of micro-channel heat exchanger, including micro-channel tubes and the afflux that is connected with micro-channel tubes At least one foregoing header in pipe, header.
Further, micro-channel heat exchanger includes micro-channel tubes and is connected to the first header and the company of micro-channel tubes upper end The second header of micro-channel tubes lower end is connected on, wherein, the second header is foregoing header.
The utility model additionally provides a kind of air conditioner, including heat exchanger, and heat exchanger is foregoing micro-channel heat exchanger.
According to header of the present utility model and micro-channel heat exchanger, air conditioner, by connecting in header and micro-channel tubes Discharge structure is provided with the surface connect, defrosting water is smoothly taken, so as to prevent defrosting water in the surface collection of header It is poly- that there is provided defrost efficiency.
Brief description of the drawings
The accompanying drawing for constituting the part of the application is used for providing further understanding to of the present utility model, of the present utility model Schematic description and description is used to explain the utility model, does not constitute to improper restriction of the present utility model.In accompanying drawing In:
Fig. 1 is the dimensional structure diagram according to header of the present utility model;
Fig. 2 is the cross-sectional structure schematic diagram according to header of the present utility model;
Fig. 3 is the dimensional structure diagram according to micro-channel heat exchanger of the present utility model.
Description of reference numerals:
1st, the first header;2nd, micro-channel tubes;3rd, the second header;4th, draining inclined-plane;5th, circulation passage;6th, mounting groove.
Embodiment
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
As depicted in figs. 1 and 2, set on the surface being connected according to header of the present utility model, header with micro-channel tubes 2 It is equipped with discharge structure.The utility model on the surface that header is connected with micro-channel tubes 2 by being provided with discharge structure, making White water can smoothly take, so as to prevent defrosting water from gathering on the surface of header, there is provided defrost efficiency.
Preferably, discharge structure is draining inclined-plane 4, is more beneficial for draining.It is highly preferred that draining inclined-plane 4 is arranged for inverted " v " Water inclined-plane 4, even if also defrosting water is arranged to both sides, so as to shorten draining stroke, improves drainage efficiency.It is highly preferred that header Cross section is in five sides, so as to the bottom surface for making header be horizontal, it is convenient to install.
With reference to shown in Fig. 2, header is triangular in shape close to the side of micro-channel tubes 2, header away from micro-channel tubes 2 one Side is rectangular.The part that i.e. header is connected with micro-channel tubes 2 is triangle, and the setting of this shape is beneficial to the stream of defrosting water It is dynamic, defrosting water is not accumulated on header, promote defrosting water to flow on chassis;The part contacted with chassis is rectangle, this The setting for planting shape increases the contact area on header and chassis, heat exchanger is easier fixation, while can make defrosting water Chassis is flowed vertically to, reduces the flow resistance of defrosting water.
Further, the mounting groove 6 coordinated with micro-channel tubes 2 is offered on draining inclined-plane 4, the insertion of micro-channel tubes 2 is installed In groove 6, and it is welded to connect with header, so as to be connected with the circulation passage 5 inside header.
The utility model additionally provides a kind of micro-channel heat exchanger, including micro-channel tubes 2 and the collection that is connected with micro-channel tubes 2 At least one foregoing header, so as to promote draining, prevents ponding in flow tube, header.Specifically, it is micro- with reference to shown in Fig. 3 Channel heat exchanger includes micro-channel tubes 2 and the first header 1 for being connected to the upper end of micro-channel tubes 2 and is connected under micro-channel tubes 2 Second header 3 at end, wherein, the second header 3 is foregoing header.This micro-channel heat exchanger is used as outer machine heat exchanger In use, more conducively defrosting water is flowed on chassis from header, defrosting water is set to accumulate on header.
It should be noted that fin can be coordinated to use between this micro-channel heat exchanger micro-channel tubes 2, can also be independent Use, its type of service is unrestricted, micro-channel heat exchanger form of the present utility model is unrestricted, can be with according to design requirement It is single or multiple rows of.
The utility model additionally provides a kind of air conditioner, including foregoing micro-channel heat exchanger, so as to prevent ponding, improves Heat exchange efficiency and defrost efficiency.
