Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, the heat exchanger of embodiment one comprises the upper heat exchanging part 20 and lower heat exchanging part 30 that are set up in parallel, and upper heat exchanging part 20 comprises heat exchanger tube 21, and lower heat exchanging part 30 comprises lower heat exchanger tube 31.Wherein, the import department of upper heat exchanger tube 21 and the import department of lower heat exchanger tube 31 are provided with throttling arrangement 40, and throttling arrangement 40 comprises the choke valve 41 and capillary 42 that are arranged in parallel.
The technical scheme of Application Example one, heat exchanger 10 comprises heat exchanging part 20 and lower heat exchanging part 30, and wherein, upper heat exchanging part 20 comprises heat exchanger tube 21, and lower heat exchanging part 30 comprises lower heat exchanger tube 31.The import department of upper heat exchanger tube 21 and the import department of lower heat exchanger tube 31 are provided with throttling arrangement 40.By arranging throttling arrangement 40, the coolant quantity of upper heat exchanging part 20 and lower heat exchanging part 30 can be adjusted according to the heat exchange amount of heat exchanger 10 zones of different simultaneously, and then make refrigerant can more flow into the region that in heat exchanger 10, heat exchange amount is large.Above-mentioned refrigerant adjustment can make the homogeneous temperature of heat exchanger tube 21 and lower heat exchanger tube 31, and the thermal efficiency improves a lot, and reduces the generation of condensation water simultaneously.Therefore the technical scheme of the present embodiment solves heat exchanger of the prior art to there is stream temperature unbalanced, the problem that condensation water is more.
Particularly, when upper heat exchanging part 20 heat exchange amount is large, close the choke valve 41 on lower heat exchanger tube 31, refrigerant is reduced by the capillary 42 on lower heat exchanger tube 31 and then flow, makes refrigerant more flow into the large upper heat exchanging part 20 of heat exchange amount, and then improves heat exchange efficiency.Above-mentioned refrigerant assigning process makes the homogeneous temperature of heat exchanger tube 21 and lower heat exchanger tube 31 simultaneously, reduces the generation of condensation water.
In like manner, when heat exchanging part 30 heat exchange amount is large instantly, close the choke valve 41 closed on heat exchanger tube 21, refrigerant is reduced by the capillary 42 on upper heat exchanger tube 21 and then flow, makes refrigerant more flow into the large lower heat exchanging part 30 of heat exchange amount.
When upper heat exchanging part 20 is identical with lower heat exchanging part 30 heat exchange amount, the choke valve 41 on upper heat exchanger tube 21 and lower heat exchanger tube 31 is all opened, and makes the coolant quantity flowing into heat exchanging part 20 and lower heat exchanging part 30 equal.
As shown in Figure 1, in the technical scheme of embodiment one, the area equation of upper heat exchanging part 20 and lower heat exchanging part 30, and then the job stability ensureing heat exchanger.
Preferably, choke valve 41 is magnetic valve.
As shown in Figure 1, heat exchanger 10 also comprises refrigerant house steward 50, first refrigerant arm 60 and the second refrigerant arm 70.Wherein, the first refrigerant arm 60 is all connected with refrigerant house steward 50 with the first end of the second refrigerant arm 70, and the first refrigerant arm 60 is connected with the import department of upper heat exchanger tube 21, and the second refrigerant arm 70 is connected with the import department of lower heat exchanger tube 31.Throttling arrangement 40 is arranged on the first refrigerant arm 60 and the second refrigerant arm 70.
As shown in Figure 2, the embodiment two according to the heat exchanger of the application is with the difference of embodiment, only the porch of lower heat exchanger tube 31 is provided with throttling arrangement 40.If heat exchanger inner space is limited, the technical scheme of embodiment two preferably can be selected.Certainly, as feasible embodiment, throttling arrangement 40 also only can be arranged on the porch of heat exchanger tube 21.
Present invention also provides a kind of air-conditioner, comprise housing according to the air-conditioning of the application and the upper air outlet that is arranged on housing and lower air outlet, wherein, upper air outlet and lower air outlet are oppositely arranged.Air-conditioner has makes the upper air-out state of air outlet, make the lower air-out state of lower air outlet and make the air-out state up and down of air outlet and the air-out simultaneously of lower air outlet, air-conditioner also comprises heat exchanger 10, be arranged in housing, heat exchanger is above-mentioned heat exchanger.Wherein, the upper heat exchanging part 20 of heat exchanger corresponds to upper air outlet and arranges, and the lower heat exchanging part 30 of heat exchanger corresponds to lower air outlet and arranges.
According to the different air-out states of air-conditioner, the throttling arrangement 40 on upper heat exchanger tube 21 and lower heat exchanger tube 31 need be adjusted, is specially:
When air-conditioner is in upper air-out state, the heat exchange amount of upper heat exchanging part 20 is large.Now reduce the aperture of the throttling arrangement 40 on lower heat exchanger tube 31, and the flow of the refrigerant of heat exchanger tube 31 reduces under making inflow, in inflow, the flow of the refrigerant of heat exchanger tube 21 increases, and then makes refrigerant more flow in the large upper heat exchanging part 20 of heat exchange amount, increases heat exchanger 10 heat exchange efficiency.The distribution of above-mentioned coolant quantity simultaneously makes the homogeneous temperature of heat exchanger tube 21 and lower heat exchanger tube 31, reduces the generation of condensation water.And preferably, when air-conditioner is in upper air-out state, the aperture of the throttling arrangement 40 on upper heat exchanger tube 21 is constant.
In like manner, when air-conditioner is in lower air-out state, the heat exchange amount of lower heat exchanging part 30 is large.Now reduce the aperture of the throttling arrangement 40 on upper heat exchanger tube 21, and the flow of the refrigerant of heat exchanger tube 21 in inflow is reduced, the flow flowing into the refrigerant of lower heat exchanger tube 31 increases, and then refrigerant is more flowed in the large lower heat exchanging part 30 of heat exchange amount.And preferably, when air-conditioner is in lower air-out state, the aperture of the throttling arrangement 40 on lower heat exchanger tube 31 is constant.
When air-conditioner is in upper and lower air-out state, upper heat exchanging part 20 is identical with the heat exchange amount of lower heat exchanging part 30, now make heat exchanger tube 21 identical with the aperture of the throttling arrangement 40 of lower heat exchanger tube 31, and then make heat exchanging part 20 in inflow identical with the coolant quantity of lower heat exchanging part 30.
It should be noted that, be defaulted as air-out when the air-conditioner of the present embodiment freezes, heat and be defaulted as lower air-out.Particularly, cold wind density is comparatively large, and because Action of Gravity Field can decline by nature, the less meeting of hot blast density is to rising, and above-mentioned air-out mode can make air-conditioner wind directly not blow human body, and then improves human body comfort.Certainly, in order to the intensity increasing refrigeration or heat, freezing and heating all to adopt upper and lower air-out state to run.I.e. upper air outlet and the equal air-out of lower air outlet during refrigeration, upper air outlet and the equal air-out of lower air outlet when heating.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
