Description

Parallel-flow heat exchanger and air conditioner

Technical field

The utility model is related to air-conditioning technical field, more specifically, is related to a kind of parallel-flow heat exchanger and flat including this The air conditioner of row stream heat exchanger.

Background technology

Existing parallel-flow heat exchanger, is also micro-channel heat exchanger, and it applies to air-conditioning technical field, mainly there is following excellent Point：Heat exchange efficiency is high, heat exchange area is big, small volume, lightweight, refrigerant charge are few, is following air conditioner refrigerating field development Trend.Parallel-flow heat exchanger applies to field of air conditioning, mainly continues to use the classical field formalism of field of automobile air conditioner parallel-flow heat exchanger, By the way of flat tube and fin stacking.But it is empty on the outside of heat exchanger when parallel-flow heat exchanger inner refrigerant is evaporated process Condensate moisture in compression ring border, separates out in heat exchanger fin and flat tube surface, accumulates in air channel and be difficult to exclude, seriously hinder wind Air flow in road, and extra heat transfer resistance is brought, reduce the heat exchange property of heat exchanger.Used as indoor evaporator, sternly It even can cause " blowing water " during weight, significantly reduce refrigeration and user's impression；And used as heat pump condenser, heat Substantial amounts of defrosting water can not be excluded in time between accumulating in fin after defrost so that frost layer is more long-pending thicker, ultimately results in heat pump cold Condenser fails, and has a strong impact on the performance of heat exchanger.At present, parallel-flow heat exchanger, which is installed, mainly uses flat tube traverse and places two kinds vertically Modes of emplacement, is limited by the form (mainly having plain film, windowing piece and corrugated plate) of fin and the structure of parallel-flow heat exchanger, produces Condensation water and defrosting water still easily between fin formed water bridge, had a strong impact on the heat exchange property of heat exchanger, this is also further Constrain the development and innovation of parallel-flow heat exchanger technology.

Utility model content

The utility model is intended at least solve one of technical problem present in prior art.

Therefore, the purpose of one side of the present utility model is to provide a kind of parallel-flow heat exchanger.

The purpose of other side of the present utility model, which is that offer is a kind of, includes the air conditioner of above-mentioned parallel-flow heat exchanger.

To achieve the above object, the embodiment of one side of the present utility model provides a kind of parallel-flow heat exchanger, bag Include：First header；Second header, is arranged at intervals with first header；Multiple flat tubes, multiple flat tubes are to each other It is located at every ground between first header and second header, and one end of each flat tube and first afflux Pipe is connected, and the other end of each flat tube is connected with second header；And fin, it is arranged on described in adjacent two Between flat tube, the fin is provided with rhone and the osculum connected with the rhone.First header and institute The second header equal level or generally horizontally disposed is stated, and first header and second header are in the vertical direction It is spaced, multiple flat tubes are vertically arranged.The fin is bent to form downwards kink and is located at the bending respectively The first side and second side of portion both sides, the first side and the second side respectively with flat tube phase described in adjacent two Connection, the osculum is located on the kink, and the rhone is located at the first side and/or the second side On.

The parallel-flow heat exchanger that the utility model above-described embodiment is provided, the first header and the second header interval are set Put, what multiple flat tubes were spaced is arranged between the first header and the second header, and each flat tube two ends respectively with First header and the second header are connected, and are connected with fin between two adjacent flat tubes, realize parallel-flow heat exchanger Normal work.When parallel-flow heat exchanger as indoor evaporator in use, parallel-flow heat exchanger inner refrigerant evaporates, outside is empty Condensate moisture in compression ring border, is separated out in the fin of parallel-flow heat exchanger and flat tube surface；As heat pump condenser in use, system Substantial amounts of defrosting water is accumulated between fin after thermalization frost.Rhone and osculum, rhone and osculum are set on fin Connect, i.e., rhone is connected with osculum, when condensed water and defrosting water loading are on fin, can by rhone and Osculum is discharged in time, reduces windage, reduces the influence of condensed water or defrosting water to heat exchange efficiency of fins, it is ensured that concurrent flow The lasting exchange capability of heat of heat exchanger, maintains refrigerating and heating systems reliability of operation, it is to avoid condensed water and defrosting water accumulate in wind Air flow in air channel is hindered in road, and brings extra heat transfer resistance.

First header and the equal horizontal positioned of the second header, and the first header and the second header are in the vertical direction Be spaced and be parallel to each other, multiple flat tubes are vertical or general vertical is set, and multiple flat tubes with the first header and the Two headers are perpendicular.

Fin is bent to form downwards first side, second side and the bending between first side and second side Portion, the end of first side is connected with one in two adjacent flat tubes, the end of second side and adjacent two it is flat Another in pipe is connected, and realizes fixation of the fin between two adjacent flat tubes, it is preferable that first side, the second side Side is connected with flat tube by way of welding；Osculum is located on kink, i.e., osculum is located at the minimum point of fin, row Tank is connected with osculum, and the condensed water and defrosting water gathered on fin is flowed under the influence of gravity into after rhone, then through row Water hole is flowed out, thus fin is bent downwards, takes full advantage of the Action of Gravity Field of condensed water and defrosting water, accelerate condensed water and The discharge of defrosting water.And after fin is bent, the heat exchange area of fin is increased, so as on appropriate increase above-below direction two The distance between fin, is further conducive to the discharge of condensed water and defrosting water, and can reduce windage.

Corresponding rhone can be set on first side and second side, it is so-called corresponding to refer to that two-phase is corresponding Rhone connects with same osculum, it is of course also possible to only set rhone on first side or second side.
