Specific embodiment
In order that the objects, technical solutions and advantages of the present invention become more apparent, below with reference to drawings and Examples,
The present invention is described in further detail.
Refer to based on present heat exchanger shown in Fig. 3 to a Fig. 7 embodiment, wherein, Fig. 3 is this embodiment
The structural representation of heat exchanger, Fig. 4 is the structural representation of separator in heat exchanger, Fig. 5 and Fig. 6 is b- in Fig. 4 respectively
B ' direction and the schematic diagram in c-c ' direction, Fig. 7 is the principle schematic that heat exchanger realizes heat exchange.
Anticipate as shown in Figures 3 to 6, the heat exchanger 2 of this embodiment includes copper pipe 21 and fin 22, and fin 22 is many
Layer, be spaced and be arranged side by side setting.Heat exchanger 2 also includes three separators, respectively separator 25, separator 26
With separator 27, each separator is both formed between two adjacent fins, and the dispersion of these three separators be formed at adjacent
Between two fins.That is, three separators spread out on the left and right width of whole heat exchanger 2.
The structure of three separators is essentially identical, below, describes the concrete structure of separator in detail taking separator 25 as a example.
Separator 25 is overall to be in rectangular structure, is formed with multiple insertion air channels 251 thereon.Each insertion air channel 251 has positioned at heat
The air inlet 252 of the inlet side 23 of exchanger 2 and the air outlet 253 of the air side 24 positioned at heat exchanger 2.And, separator
25 and insertion air channel 251 configured according to following restrictions: enter and from heat exchanger 2 from the inlet side 23 of heat exchanger 2
The wind part of air side 24 blowout does not carry out heat exchange with fin through insertion air channel 251.That is, it is multiple on separator 25
Insertion air channel 251 formed independent of fin between air intake gap air channel, and separator 25 has in itself preferably every cold/heat-insulated
Performance, thus so that the wind in insertion air channel 251 does not carry out heat exchange with fin, especially two adjacent fins of separator 25.
As preferred embodiment, each separator is made using nylon material, not only have certain every cold/heat-proof quality, also
There is certain toughness, be easy to mutually be fixed with copper pipe 21.
Thus, the separator in insertion air channel 251 is had so that entering from heat exchanger 2 by setting in heat exchanger 2
Wind side 23 enters into the wind in heat exchanger 2, and partly the air intake gap between the crack through fin 22 and fin and fin is blown over, with
Fin 22 carries out heat exchange, and the wind after heat exchange blows out from the air side 24 of heat exchanger 2；Also have partly directly through insertion air channel
251, then blow out from the air side 24 of heat exchanger 2, and this part wind does not occur heat exchange.And, after these heat exchanges
Wind and do not occur the wind of heat exchange to proceed by mixing at the air side 24 of heat exchanger 2, continue forward to blow out when
Time proceeds to mix, and ultimately forms the mixing wind of proper temperature, mix homogeneously.This heat exchange is adopted in indoor apparatus of air conditioner
After device, the mixing wind of proper temperature blows out from air outlet of indoor set, reach go out during refrigeration cool and not cold, wind heat when heating
And not dry comfortable sexual experience, even if machine air outlet also will not feel sometimes hot and sometimes cold indoors, improve air-conditioning user
Comfortableness.
Principle schematic referring to Fig. 7 is illustrated, when air conditioner refrigerating runs, the air intake of the inlet side 23 of heat exchanger 2
Temperature is 30 DEG C.After 30 DEG C of high warm air blows out from the insertion air channel of separator 25, separator 26 and separator 27, temperature is still
For 30 DEG C.And 30 DEG C of the high warm air that the air intake gap between fin 22 crack and fin and fin is passed through is carried out with fin 22
After heat exchange, form 19 DEG C of cold wind, blow out from the air side 24 of heat exchanger 2.Therefore, in the air side 24 of heat exchanger 2
Place there are 19 DEG C of low temperature wind and 30 DEG C of high warm air, and this two parts wind will begin to be mixed at air side 24,
Continue mixing to during air outlet of indoor set flowing, finally, from air outlet of indoor set blowout in the presence of indoor machine fan
Temperature is 23 DEG C of suitable wind.Therefore, in the comfort conditioned of the temperature realized using heat exchanger 2 to indoor wind, improve room
The air-supply comfortableness of interior machine.
As preferred embodiment, position on heat exchanger 2 for the separator is to be configured to air conditioning chamber in heat exchanger 2
The air inlet in insertion air channel when in interior machine, on separator is just advisable to the air inlet of indoor set, to improve insertion air channel apoplexy
Smooth outflow.
As preferred embodiment, taking insertion air channel 251 as a example, the intermediate formation in insertion air channel 251 has throttling
Portion 255, is formed with restriction 254 in restriction 255.And, restriction 255 is from the air inlet 252 near insertion air channel 251
One end present at restriction 254 interior bore tapered, from restriction 254 near insertion air channel 251 air outlet 253 one
End assumes interior bore flaring.And, restriction 254 is greater than restriction with the air inlet 252 in insertion air channel 251 apart from h1
254 with the air outlet 253 in insertion air channel 251 apart from h2.That is, restriction 254 is closer to air outlet 252.Thus, through celebrating a festival
The pore throttling of stream portion 255 and restriction 254, the air-flow of air outlet 253 blowout from insertion air channel 251 is diverging airflow, more
Be conducive to improving this part diffusing air current and mix with the uniform of the air-flow after fin heat exchange.
Above example is only in order to illustrating technical scheme, rather than is limited；Although with reference to aforementioned reality
Apply example the present invention has been described in detail, for the person of ordinary skill of the art, still can be to aforementioned enforcement
Technical scheme described in example is modified, or carries out equivalent to wherein some technical characteristics；And these are changed or replace
Change, do not make the essence of appropriate technical solution depart from the spirit and scope of claimed technical solution of the invention.
