Abstract
The utility model discloses an inserted sheet passageway heat exchanger that declines, it includes fin, S type mouth organ pipe and collector tube, the collector tube mouth is connected with the connecting pipe, it has U type groove to open on the fin, and U type inslot is provided with the turn -ups that the clamping opening musical instrument was managed along the trend in groove, and the S type mouth organ pipe after bending inserts the U type inslot interference fit of fin. U type groove sets up on a side of single fin, the width of the degree of depth more than or equal to S type mouth organ in U type groove pipe. This technical scheme inserted sheet passageway heat exchanger that declines has cancelled the fixed frock of brazing, has got rid of the inefficiency, and influences the heavy handled scheduling problem of quality.
Description
Technical field:
The utility model relates to one and is mainly used in refrigeration industry, is particularly suited for the air-cooled condenser of the forced refrigeration of refrigerator refrigeration system, particularly a kind of blade inserting micro channel heat exchanger.
Background technology:
nullCurrently，Requirement for Large Copacity refrigeration system，The heat exchanger effectiveness improving constantly heat exchanger is needed to meet，Therefore，All constantly bring forth new ideas in refrigeration accessory industry and improve heat exchanger effectiveness，As micro channel heat exchanger emerging in refrigeration for refrigerator industry，It becomes the favor of large-capacity refrigerator by less volume and the advantage such as higher thermal exchange rate and relatively low cost，This micro channel heat exchanger primary structure is as shown in Figure 1，It includes by harmonica-shaped tube 1、Fin 2、Collector tube 3 and 2 forms，The material of fin 1 typically selects aluminium foil、Aluminium foil is pre-machined into the wavy of W type，Harmonica-shaped tube 2 is bent into S type in advance，Fin 2 and harmonica-shaped tube 1 are brazed together by the way of soldering oven soldering by fin 2，Collector tube 3 soldering is at the import and export two ends of harmonica-shaped tube 1，On collector tube 3, Welding has in connecting tube 4，Constitute micro-channel heat exchanger，The heat exchanger of this structure is owing to there being micropore in harmonica-shaped tube，Cold-producing medium is divided into multiply in harmonica-shaped tube 1，Per share water diameter is less than or equal to 1，The heat exchange efficiency of heat exchanger improves 30-50% under this configuration，Fin 2 and harmonica-shaped tube 1 pass through Welding，Fin and harmonica-shaped tube is enable to combine closely，The heat exchanger making this structure has the advantages that heat exchange efficiency is high，Although this exchanger heat exchange efficiency is high，However it is necessary that and fin and harmonica-shaped tube are carried out Welding by integral braze-welded stove，In order to ensure the firm of welding and weld size，Enter soldering oven welding to need to use the high temperature resistant and the most oxidizable materials such as stainless steel to make clamping tool，Workpiece is carried out in frock pre-clamping，The most related frock is put in soldering oven together and is sintered.This processing technology is extremely complex, needs every workpiece is installed clamping tool, and production efficiency is low, and finished product is affected by frock clamping degree, and efficiency low quality is unstable.
How to develop steady quality, the target that technique is simple, the heat exchanger of lifting operating efficiency is those skilled in the art's sustained improvement and innovation.
Summary of the invention:
It is high that task of the present utility model proposes a kind of working (machining) efficiency, and quality is easily controlled and stable a kind of blade inserting micro channel heat exchanger.
Task of the present utility model so completes, a kind of blade inserting micro channel heat exchanger, it includes fin, S type harmonica-shaped tube and collector tube, collector nozzle connects connecting tube, it is characterized in that: on described fin, have U-type groove, in U-type groove, the trend along groove is provided with the flange clamping harmonica-shaped tube, interference fit in the U-type groove of the S type harmonica-shaped tube insertion fin after bending.U-type groove is arranged on a side of single fin, and the degree of depth of U-type groove is more than or equal to the width of S type harmonica-shaped tube.The two ends of the harmonica-shaped tube of S type are provided with end plate.
The utility model has the effect that the technical program blade inserting micro channel heat exchanger eliminates soldering fixing tool, eliminates efficiency low, and affects the problems such as difficult quality control.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；Fig. 2 is fin structure schematic diagram.
Drawing illustrates: 1, S type harmonica-shaped tube, 2, fin, 3, collector tube, 4, connecting tube, 5, end plate, 6, flange, 7, U-type groove.
Detailed description of the invention:
Positioned by plug-in type between fin and harmonica-shaped tube involved by the technical program, the most integral sintered, above structural change prior art soldering fixing tool, solve and install between the industry existing industry fin and harmonica-shaped tube and the bottleneck of processing technology.
Specific embodiment is as depicted in figs. 1 and 2, the utility model is made up of harmonica-shaped tube 1, fin 2, collector tube 3 and connecting tube 4, U-type groove 7 is had on described fin, in U-type groove, the trend along groove is provided with the flange 6 clamping harmonica-shaped tube, U-type groove is arranged on a side of single fin, and the quantity of U-type groove is to require to be configured according to rate of heat exchange, and each U-type groove and flange equivalently-sized, and be parallel to each other, the degree of depth of U-type groove is more than or equal to the width of S type harmonica-shaped tube.
Described harmonica-shaped tube 1 is bent into S type, S type harmonica-shaped tube 1 after bending inserts interference fit in the U-type groove 7 of fin 2, add man-hour, fin 2 is swung in pendulum frock beforehand through automation equipment, automatically pendulum equipment is ripe prior art, U-type groove is upwards, then by the U-type groove of bending S type harmonica-shaped tube 1 overall press-in fin 2, end plate 5 is installed at the two ends of the harmonica-shaped tube of S type, collector tube soldering is at the two ends of S type harmonica-shaped tube, on it, connection has connecting tube 4, integral braze-welded stove to carry out soldering sintering, completes the assembling of product.
Owing to being provided with flange in the type groove of the U of fin 2, thus increase fin and the contact area of S type harmonica-shaped tube, after in the U-type groove of S type harmonica-shaped tube press-in fin, S type harmonica-shaped tube and fin monnolithic case size are the most fixing, need not other any frocks and just can have enough to meet the need sintering, therefore improve the working (machining) efficiency of product.
