2, air conditioner can fast-refrigerating, has improved heat exchange efficiency, and has efficiently solved the emission problem of air conditioner condensed water.
In order to understand the present invention more clearly, set forth the specific embodiment of the present invention below with reference to description of drawings.
The specific embodiment
As shown in Figure 1, 2, novel vaporation-type parallel-flow heat exchanger 1 of the present invention includes the last header 11 that is arranged in parallel and lower header 12, and some flat tubes 13 that is arranged between two headers 11,12 and connects with header 11,12.Above-mentioned two ends of going up header 11 and lower header 12 are respectively arranged with end cover 14, and the described inner chamber of going up header 11 and lower header 12 to be respectively arranged with the header sealed separation be a plurality of chambers and then change the cutoff board 15 that working medium flows to.Further, the described header 11 of going up is provided with entrance sleeve 16 and discharge connection 17.
Above-mentioned flat tube 13 is the microchannel porous flat pipe, the combined integrated moulding of pegging graft of itself and last header 11, lower header 12.Further, the section of described porous flat pipe 13 is flat oblong, the facial contour size is thick * wide be T * W, thickness T is not more than 2mm, width W is 8mm~25.4mm, and section is provided with the inequality through hole that hydraulic diameter is not more than 0.7mm, through hole be shaped as rectangular opening, triangle or circle; Preferably, described porous flat pipe adjacent shaft distance is for being not more than 6.3mm.
As shown in Figure 3, the air conditioner of the above-mentioned heat exchanger of application of the present invention, include evaporimeter 2, compressor 3, fan system, airduct, spray system and vaporation-type parallel-flow heat exchanger 1, described evaporimeter 2, compressor 3 and vaporation-type parallel-flow heat exchanger 1 are connected to form the refrigerant loop by pipeline.
The said fans system includes fan system 41 and following fan system 42, last fan system 41 and evaporimeter 2 position corresponding matching, following fan system 42 and vaporation-type parallel-flow heat exchanger 1 position corresponding matching; Reach described airduct and include blast pipe 51 and discharge pipe 52, blast pipe 51 is connected with following fan system 42 respectively to use with discharge pipe 52 and cooperates.
Above-mentioned spray system includes a spray box 61, reaches a drip tray 62, spray box 61 is arranged at evaporimeter 2 belows and is arranged at vaporation-type parallel-flow heat exchanger 1 top, and drip tray 62 is arranged at vaporation-type parallel-flow heat exchanger 1 below and is connected use by a water pump 63 with spray box 61 and cooperates.
The operation principle of air conditioner of the present invention is as described below: the high temperature and high pressure steam refrigerant that compressor 3 emits enters the last header 11 of heat exchanger 1 by the entrance sleeve 16 of heat exchanger 1, uniform by last header 11 to microchannel porous flat pipe 13, the high temperature and high pressure steam refrigerant is delivered to heat by modes such as convection current and conduction the surface of microchannel porous flat pipe 13, at this moment, water evenly sprays microchannel porous flat pipe 13 surfaces in the spray box 61, directly evaporation behind the heat of absorption microchannel porous flat pipe 13, take away from discharge pipe 52 by the wind that following fan system 42 is advertised, the shower water on microchannel porous flat pipe 13 surfaces drops into drip tray 62, be back in the spray box 61 by water pump 63, and the refrigerant after the cooling enters in the evaporimeter 2 by discharge connection 17 and throttling arrangement, at this moment, room air is by flow through evaporimeter 2 and carry out heat exchange with evaporimeter 2 of last fan system 41, the cooling back is discharged into the interior space by air outlet, and water droplet is formed in the condensation of airborne steam chance, be discharged in the spray box 61, the refrigerant that has absorbed heat afterwards enters compressor once more, the heat transfer process of a beginning new round.
The present invention is not limited to above-mentioned embodiment, if various changes of the present invention or modification are not broken away from the spirit and scope of the present invention, if these are changed and modification belongs within claim of the present invention and the equivalent technologies scope, then the present invention also is intended to comprise these changes and modification.
