Abstract
The invention discloses flat pipe and fin structures of a parallel flow heat exchanger, which comprise a plurality of flat pipes inserted on header pipes on two ends of the heat exchanger, fins are arranged between adjacent flat pipes, and micro-channels on the flat pipes are communicated with the header pipes on the two ends of the heat exchanger; and longitudinal middle parts at two sides of each flat pipe protrude, and correspondingly each fin is of a structure in which the longitudinal middle parts at two sides are sunken, thus avoiding the fins moving transversely to result in falling-off. Preferably, the protruding parts of the longitudinal middle parts at the two sides of each flat pipe are subjected to smoothing transition, and correspondingly the sunken structure of the longitudinal middle parts at the two sides of each fin is also subjected to smoothing transition, thus facilitating processing and manufacturing of components. After assembly brazing is completed, the fins can remain stationary transversely, thus effectively avoiding the fin moving transversely to result in falling-off; and after long-term service, the fins do not drop even though welding spots between the fins and the flat pipes are corroded or cracked owing to vibration and the like, thus achieving relatively stable heat exchange efficiency of the heat exchanger, facilitating overall processing and manufacturing, and improving excellence rate of assembly processing of the heat exchanger.
Description
Technical field
The present invention relates to a kind of parts of parallel flow heat exchanger, specifically relate to a kind of flat tube and fin structure of parallel flow heat exchanger.
Background technology
Parallel flow heat exchanger is an equipment of realizing that heat transmits between cold fluid and hot fluid, is widely used in fields such as HVAC.Parallel flow heat exchanger generally comprises two headers that are parallel to each other, and is provided with some parallel substantially heat radiating flat tubes between two headers, and soldering has the heat transmission fin between adjacent flat tube.Fin is processed by aluminium matter sheeting, is wave structure more, and the lateral surface of its crest and trough supports and is located on the two sides up and down of flat tube, and final soldering is fixed.But because fin and flat tube just are abutted against the frictional force of touching; the phenomenon that some fins come off takes place in regular meeting in welding process or after the welding; particularly at some large-scale heat exchangers; go sticking fixing or the secondary welding etc. of mending all can occur welding unreliable and the stifled more high defective of product weldering again; the fraction defective of product is higher relatively, also makes the corresponding increase of manufacturing cost.After heat exchanger was using for many years, the solder joint of fin and flat tube is corroded or the quilt vibrations are ftractureed etc. can make all that also fin comes off in addition.These all can reduce the heat exchange efficiency of whole heat exchanger.
Summary of the invention
The present invention solves above-mentioned existing in prior technology technical problem, and a kind of flat tube and fin structure of parallel flow heat exchanger is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of flat tube of parallel flow heat exchanger and fin structure, some flat tubes are plugged on the header at two ends, be provided with fin between adjacent flat tube, described flat tube both sides longitudinal middle part protuberance, fin is both sides longitudinal middle part concave configuration accordingly, prevents that fin from laterally moving and come off.
As preferably, the longitudinal middle part bump fairing transition of described flat tube both sides, also fairing transition of the concave configuration of fin both sides longitudinal middle part accordingly.
The present invention is designed to both sides longitudinal middle part ridge structure with flat tube, fin is both sides longitudinal middle part concave configuration accordingly, after assembling and soldering is finished, can be so that fin be maintained fixed in the horizontal, can avoid fin laterally to move effectively and come off, and after using for many years,, make that the heat exchange efficiency of heat exchanger is relatively stable even the solder joint of fin and flat tube is corroded or ftractureed etc. by vibrations and also can not cause fin to come off; In the use, the condensed water on the fin and on the flat tube can emit smoothly along the inclined surface of flat tube, and whole processing and manufacturing is also convenient a lot, can improve the acceptance rate of the assembling processing of heat exchanger.Have characteristics such as simple in structure, reasonable in design.
Description of drawings
Fig. 1 is a kind of structural representation of heat exchanger of the present invention;
Fig. 2 is a kind of structural representation of flat tube of the present invention and fin.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, technical scheme of the present invention is described in further detail.
Embodiment: referring to Fig. 1 and Fig. 2, heat exchanger of the present invention comprises some flat tubes 2 that are plugged on the two ends header 1, and 2 of adjacent flat tubes are provided with fin 3, and the microchannel 4 on the flat tube 2 is communicated with the header 1 at two ends.Flat tube 2 both sides longitudinal middle parts protuberance wherein, fin 3 be both sides longitudinal middle part concave configuration accordingly, can prevent that fin is laterally mobile and comes off.Preferably, flat tube 2 both sides longitudinal middle part bump fairing transition, the component processing manufacturing is convenient in the also fairing transition of concave configuration of fin 3 both sides longitudinal middle parts so accordingly.
The present invention is designed to both sides longitudinal middle part ridge structure with flat tube, fin is both sides longitudinal middle part concave configuration accordingly, after assembling and soldering is finished, can be so that fin be maintained fixed in the horizontal, can avoid fin laterally to move effectively and come off, and after using for many years,, make that the heat exchange efficiency of heat exchanger is relatively stable even the solder joint of fin and flat tube is corroded or ftractureed etc. by vibrations and also can not cause fin to come off; Whole convenient processing and manufacture can improve the acceptance rate of the assembling processing of heat exchanger.
At last, should be pointed out that above embodiment only is the more representational example of the present invention.Obviously, the invention is not restricted to the foregoing description, many distortion can also be arranged.Every foundation technical spirit of the present invention all should be thought to belong to protection scope of the present invention to any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. the flat tube of a parallel flow heat exchanger and fin structure, some flat tubes are plugged on the header at two ends, be provided with fin between adjacent flat tube, it is characterized in that described flat tube both sides longitudinal middle part protuberance, fin is both sides longitudinal middle part concave configuration accordingly, prevents that fin from laterally moving and come off.
2. the flat tube of parallel flow heat exchanger according to claim 1 and fin structure is characterized in that the longitudinal middle part bump fairing transition of described flat tube both sides, also fairing transition of the concave configuration of fin both sides longitudinal middle part accordingly.
