Abstract
The utility model discloses a parallel-flow heat exchanger structure which comprises header pipes respectively arranged on the inlet side and the outlet side of a heat exchanger, a heat exchange unit arranged between the two header pipes, and a heat exchanger side board, wherein the heat exchange unit is formed by a flat pipe bundle and fins, two ends of the flat pipe bundle are respectively communicated with the header pipes on two sides, a plurality of flat pipe holes are arranged in the fins in parallel and at fixed intervals, and the flat pipe bundle is inserted into the flat pipe holes of a plurality of parallel fins. The fins can protect the flat pipes, thus effectively protecting the parallel-flow heat exchanger, and avoiding the problem of leakage caused by the situation that the flat pipes can not bear high system pressure as the walls of the flat pipes become thin due to collision. Therefore, the reject ratio in production is lowered, the production cost is saved, user complaint is reduced, and the brand image is promoted.
Description
Technical field
The utility model relates to the air-conditioner technical field, more particularly, relates to a kind of parallel-flow heat exchanger structure.
Background technology
Make the field at the family expenses air-conditioner, domestic air conditioner is formed and is mainly comprised: compressor, condenser, throttling arrangement, evaporimeter.Present domestic air conditioner is generally air-cooled, and its heat exchanger generally is the air cooling fin formula, i.e. fin cover copper pipe formula.Some present efficient machines have improved the complete machine Energy Efficiency Ratio in order to improve the monomer exchange capability of heat of heat exchanger, adopt the full aluminium heater of concurrent flow, i.e. micro-channel heat exchanger.The evaporation tube that the full aluminium heater of concurrent flow adopts is a flat tube configuration, and the full aluminium heater of concurrent flow has the incomparable heat exchange effect of conventional heat exchanger, and unit draught area exchange capability of heat and unit volume exchange capability of heat are all considerably beyond the heat exchanger of routine.This aluminium foil fin and the flat tube of prior art are welded together through wave soldering, and its coating surfaces fusing point is lower than the fusing point of aluminium, and at first fusing fully combines with flat tube in heating process.This structure makes flat tube expose the appearance at the full aluminium heater of concurrent flow; Because the tube wall of flat tube is thinner; The full aluminium heater of concurrent flow can receive collision in various degree unavoidably in carrying, transportation and assembling process, the flat tube that exposes in the outside is easy to hit distortion.Deformation position wall thickness becomes thinner, and when air-conditioner moved, the condensing pressure that deformation place will can't bear high pressure owing to the wall thickness of attenuation leaked.Thereby cause to produce and return bag, even cause customer complaint, and influence brand image, cause great loss.
The utility model content
The utility model is in order to overcome the deficiency that above-mentioned prior art exists, and provides a kind of simple and have a parallel-flow heat exchanger structure of protection flat tube function.
The technical scheme that the utility model adopts is: a kind of parallel-flow heat exchanger structure; Comprise the header that lays respectively at heat exchanger inlet side and outlet side; Be located at heat exchange unit and heat exchanger side plate between two headers, said heat exchange unit is made up of flat tube bundle and fin, and the two ends of said flat tube are communicated with the header of both sides respectively; Be arranged with a plurality of flat tubes hole in parallel with fixed intervals on the said fin, said flat tube bundle interts in the flat tube hole of many parallel fins.
The flat tube hole of said fin is provided with flange, said flange perpendicular to the fin setting so that the minimum spacing of adjacent fins be flange stretch out the height.
Many parallel microchannels are set in the said flat tube.
The inwall of said microchannel is smooth.
The inwall of said microchannel is provided with the rib of many zigzags.
The two ends, flat tube hole of said fin are apart from the about 5mm of the dual-side of fin.
Said two headers are connected with fairlead respectively.
Compared with prior art, the utlity model has following advantage:
The fin of the utility model can be protected flat tube, thereby effectively protects parallel-flow heat exchanger, the problem that the system pressure that the tube wall of avoiding flat tube makes flat tube can't bear high pressure because of the collision attenuation leaks.Return the bag rate thereby reduced to produce, practiced thrift production cost, reduce user's complaint, improve the image of brand.

The specific embodiment
Below pass through the specific embodiment, and combine accompanying drawing that the utility model is described further.
Referring to Fig. 1-Fig. 5, the utility model provides a kind of parallel-flow heat exchanger structure, comprises the header 1 that lays respectively at heat exchanger inlet side and outlet side; Be located at heat exchange unit and heat exchanger side plate 2 between two headers 1; Heat exchange unit is made up of flat tube bundle and fin 4, and the two ends of flat tube bundle are communicated with the header 1 of both sides respectively, and two headers 1 are connected with fairlead respectively; The flat tube bundle is made up of the parallel flat tube 3 of N bar; Be arranged with a plurality of flat tubes hole 41 in parallel with fixed intervals on the fin 4,41 two ends, flat tube hole are about 5mm apart from the dual-side of fin 4, and the flat tube bundle interts in the flat tube hole 41 of many parallel fins 4.Fin 4 can adopt light straight fins, corrugated fin, slitted fin, and present embodiment adopts the light straight fins, and material is an aluminium foil.The flat tube hole 41 of fin 4 is provided with flange 42, and flange 42 is provided with perpendicular to fin 4, flange 42 stretch out the minimum vertical spacing of highly confirming two adjacent fins 4.
Referring to Fig. 3, many microchannels that are arranged in parallel 31 are set in the flat tube 3,, the inwall of microchannel 31 is provided with the rib of many zigzags in the present embodiment, and in a further embodiment, the inwall of microchannel 31 can be smooth.When cold-producing medium flows, can effectively increase heat exchange area and the disturbance that increases cold-producing medium in the microchannel that has rib 31, the augmentation of heat transfer effect, its heat-transfer effect is considerably beyond the evaporation tube of routine.
Referring to Fig. 4; Fig. 5 and Fig. 6; Flat tube 3 is aimed at the position in the flat tube hole 41 on the fins 4, intert N bar flat tube 3 in the into corresponding flat tube hole 41 then, the fin 4 with needs all packs in the N bar flat tube 3 again; Surround whole flat tube 3 until fin 4, the good back of cover is carried out integral solder with the welding manner of wave soldering with header 1, heat exchange unit, heat exchanger side plate 2 and fairlead.Flat tube 3 after welding is good is all surrounded by fin 4, does not expose outside, thereby makes fin 4 effectively protect flat tube 3.
