Abstract
The utility model discloses an inner leakage prevention type spacer structure of a micro-channel heat exchanger. The inner leakage prevention type spacer structure is characterized in that an inner leakage prevention type spacer is welded on the inner surface of a collecting pipe and penetrates through two ends of the collecting pipe. Leakage is easily generated at the inner part of a conventional micro-channel heat exchanger structure spacer when welding is carried out at the inner side; according to the inner leakage prevention type spacer structure of the micro-channel heat exchanger disclosed by the utility model, the inner leakage probability due to the welding of the spacer is completely eliminated, the product quality reliability is increased, and the production additional cost can be reduced.
Description
Technical field
The utility model relates to the anti-interior leakage formula partition of a kind of micro-channel heat exchanger, is specially adapted to the micro-channel heat exchanger field of diameter 10-50 (mm) header.
Background technology
Traditional air-condition heat exchanger adopts fin tube type structure always, its technology is relatively ripe, but along with traditional air-conditioning to compact, efficiently and cheaply require to improve constantly, fin-tube heat exchanger is more and more difficult to meet the demands, simultaneously, this traditional fin-tube heat exchanger is the easy shortcoming such as leakage of lower, bulky, the cold-producing medium of ubiquity heat exchange efficiency also, therefore, the better micro-channel heat exchanger of performance starts to be applied to an air-conditioning equipment, and its compact conformation, heat exchange efficiency high have breakthrough meaning to the development of air-conditioning equipment.
In the prior art, micro-channel heat exchanger generally comprises the various structures form that adopts, and the general flat tube with multiple microchannels heat exchanger that adopts of heat exchanger tube is provided with heat exchange fin between flat tube, and flat tube is fixed on header by welding manner.Wherein, the form of header is also varied, and general section is circular.Now micro-channel heat exchanger is on the market mainly towards the refrigeration plant of domestic air conditioning equipment and industrial circle.Partition and the header of tradition micro-channel heat exchanger adopt one-sided connected mode of cutting groove; as Fig. 4; due to die-cut, contact with header inwall; contact-making surface, because scolder is less, often can cause the disconnected weldering of top arc position or rosin joint, once there is this situation like this; when air-conditioning system is moved; make cold-producing medium directly by leak source, enter next flow process without micro-channel flat, thereby do not reach the performance of expection, the heat exchange property of air-conditioning system is affected.
Utility model content
The purpose of this utility model is to overcome the interior leakage of micro-channel heat exchanger, provides a kind of micro-channel heat exchanger anti-interior leakage formula partition, and it comprises header, anti-interior leakage formula partition, and in preventing, leakage formula partition has run through header both sides when assembling.
Described collecting pipe material comprises base material AA3003, and outside composite solder comprises AA4045 or AA4343 or AA4047.
Described header caliber comprises Φ 10mm～Φ 200mm.
Described partition thickness comprises 0.8mm～5mm, runs through header both sides, is not limited to the contour structures of partition.
Use the utility model, at the relative both sides of header fluting, in anti-interior leakage formula partition standing groove, by brazing, reduced the risk of leaking in partition, thereby saved the costs of production and operation of enterprise.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the anti-interior leakage formula partition of the utility model and header assembling;
Fig. 2 is the schematic diagram of the anti-interior leakage formula partition of the utility model;
Fig. 3 is the schematic diagram that need slot when leakage formula partition assembles on header in the utility model assembling is prevented;
Fig. 4 is conventional spacer structure;
In figure, header 1, anti-interior leakage formula partition 2.
The specific embodiment
As shown in Figure 3, the anti-interior leakage formula structure of micro-channel heat exchanger comprises header, anti-interior leakage formula partition; A groove is respectively opened at the two ends of header 1, and anti-interior leakage formula partition inserts wherein, by brazing, makes header inner chamber independently separately.
In micro-channel heat exchanger is anti-, leakage formula spacer structure comprises header (1), anti-interior leakage formula partition (2).
Described anti-interior leakage formula partition has run through header both sides when assembling.
Described collecting pipe material comprises base material AA3003, and outside composite solder comprises AA4045 or AA4343 or AA4047.
Described header caliber comprises Φ 10mm～Φ 200mm.
Described partition thickness comprises 0.8mm～5mm, runs through header both sides, is not limited to the contour structures of partition.
