Abstract

The invention discloses a pure backflow less-contact duct piece integrated high-efficiency air pipe heat exchanger which is formed by performing an integrated processing technology on a light tube or a finned tube which is not limited by a technology, and the technology limitation and the heat resistance are avoided. Air is blown from one end of a ventilating pipeline to the other end, and no ineffective section and no ineffective surface exist; an external wrapping ventilating pipeline can be either straight or bent, so that the heat exchange efficiency is greatly improved, and the temperature grade is increased; a working medium enters from the lower part and leaves from the upper part; the flowing paths are the same, and liquid distribution and gas distribution are uniform. The heat exchange efficiency is greatly improved.

Description

Pure adverse current few contact section of jurisdiction integrated high-efficient airduct heat exchanger

Technical field: air conditioner refrigerating;

Background technology: traditional wind heat exchange type air-conditioning, the heat exchanger of refrigeration, limitting due to technique adopts fin poling through machine expand tube, or water no matter rise be that machine rises or water rises, all inevitably between fin and copper pipe, leave space thermal resistance, thicken heat exchanger tube thickness, cause thermal resistance, again because heat exchanger tube needs the snakelike link of lacing film, each loop needs welding, there is inactive portion end, wind blows sidewards facing to heat exchanger tube, invalid is by wind face, and Multi-layer exchanging heat device, first and tail disturbs in the heat exchange air-flow overlap of flowing, in addition suction and exhaust ports is nearer, air flow shortcircuit, heat exchange efficiency is caused to decline, summary of the invention: the present invention is shown in that Fig. 1-7 is with light pipe or not by the finned tube of technique restriction, integral type processing technology does not have technique to limit and does not have thermal resistance, wind blows to the other end by ventilation shaft one end, there is no invalid section, there is no invalid.Outsourcing ventilation shaft can be straight or curved, can establish multiple drainpipe inlet and outlet because of heat exchanger tube usually long at 10-15 rice, the ventilation shaft length of outsourcing is suitable, distant with it, can not cause the short circuit of heat exchange wind, substantially increase heat exchange efficiency, improve temperature grade, working medium enter under, go out upper, flow process is equal, and separatory, gas are even.Heat exchange efficiency improves greatly, reduces energy consumption 21%-25%.

Accompanying drawing illustrates: Fig. 1 Fig. 4 is heat exchanger band finned tube of the present invention respectively, sectional drawing not with finned tube; Fig. 2, Fig. 5 are heat exchanger band finned tube header end of the present invention schematic diagram respectively, are not with finned tube header end schematic diagram; Fig. 3, Fig. 6, be respectively band finned tube inlet end schematic diagram of the present invention, be not with finned tube inlet end schematic diagram; Fig. 7, be airduct heat exchanger band finned tube of the present invention, be not with finned tube end design principle figure.

Air port and the end cap of be heat exchanger tube, 04 be drip tray (if doing cryogenic vaporizer also will have drip tray defrost hot gas hot Buddhist thermoelectricity heater 15), 11 are drainpipes (if doing cryogenic vaporizer also will have heater 14) 09,10 are lifting parts, 02 be shell, 07 be total header, 08 to be air-breathing return pipe, 12,13 be one that detailed description of the invention: Fig. 1-Fig. 7,01 is fin, 03; Between air port and heat exchanger, according to demand tunable wind-guiding plate 16. can be housed

Claims

1. the pipe in ventilation shaft formula and fin integrated heat-exchanger, light pipe heat exchanger, without the need to linking between except head and the tail two ends need connect.

2. the noiseless electrodeless heat exchange of pure adverse current.

3. working medium enter under, go out in upper flow process equal.

4. pure adverse current few contact section of jurisdiction integrated high-efficient airduct heat exchanger.
