Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following embodiments and accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
It is found that the liquid refrigerant is uniformly distributed to the heat exchange tube set by the liquid distributor 30 after entering the housing 10 through the liquid inlet 21. The liquid refrigerant is continuously evaporated on the heat exchange tube group. The distribution uniformity of the liquid refrigerant can be poor under the influence of the gaseous refrigerant, and the heat exchange uniformity is poor.
Fig. 1 shows a first embodiment of the evaporator of the present invention, which comprises a housing 10, a liquid inlet 21 and a gas outlet 22, wherein the liquid inlet 21 and the gas outlet 22 are arranged on the housing 10. The evaporator further comprises a liquid distributor 30, a first heat exchange pipe group 41, a second heat exchange pipe group 42 and a first liquid equalizing pipe group 51, the liquid distributor 30 is arranged at the upper part in the shell 10 and corresponds to the liquid inlet 21, and the liquid distributor 30 is used for dispersing a refrigerant introduced into the liquid inlet 21. A first heat exchange tube group 41 and a second heat exchange tube group 42 are provided in the case 10, and the second heat exchange tube group 42 is located below the liquid distributor 30. The first liquid equalizing pipe group 51 is arranged in the shell 10 and located between the first heat exchange pipe group 41 and the second heat exchange pipe group 42, the pipe diameter of a heat exchange pipe of the first liquid equalizing pipe group 51 is smaller than that of the heat exchange pipe of the first heat exchange pipe group 41, and the distribution density of the heat exchange pipes of the first liquid equalizing pipe group 51 is greater than that of the heat exchange pipes of the first heat exchange pipe group 41.
By applying the technical scheme of the present invention, after the refrigerant flows through the first heat exchange tube set 41, the refrigerant falls on the first liquid equalizing tube set 51. Because the heat exchange tubes of the first liquid equalizing tube group 51 have small tube diameters and large distribution density, when the refrigerant flows through the first liquid equalizing tube group 51, the refrigerant is randomly distributed more uniformly by the heat exchange tubes of the first liquid equalizing tube group 51, so that the refrigerant can be equalized again, and the refrigerant can uniformly fall on the second heat exchange tube group 42 for heat exchange. Therefore, the heat exchange uniformity of the evaporator is improved, and the overall heat exchange efficiency is improved.
Optionally, in the technical solution of the present embodiment, the liquid inlet 21 and the air outlet 22 are disposed at the top of the housing 10, and as another optional embodiment, the liquid inlet 21 and the air outlet 22 may also be disposed at the side of the housing 10.
It should be noted that the liquid equalizing tube group and the heat exchange tube group are also composed of heat exchange tubes capable of performing evaporation heat exchange.
As shown in fig. 1, preferably, in the solution of the first embodiment, the evaporator further includes an overheating heat exchange tube set 60, and the overheating heat exchange tube set 60 is disposed at the lower part in the casing 10 and below the second heat exchange tube set 42. In the process of using the evaporator, the refrigerant that is not gasified by the heat exchange tube set is accumulated at the lower part of the shell 10, and the overheating heat exchange tube set 60 at the lower part of the shell 10 exchanges heat with the part of the refrigerant, so that the part of the refrigerant is also evaporated into the gaseous refrigerant.
In the process of using the evaporator, the phenomenon of air absorption and liquid carrying can occur when the liquid refrigerant is evaporated, which is not beneficial to full heat exchange. As a preferred implementation, as shown in fig. 1, in the technical solution of the first embodiment, the evaporator further includes a synergistic tube set 70, and the synergistic tube set 70 is disposed in the casing 10 and below the superheated heat exchange tube set 60. The heat exchange pipe diameter of the synergistic pipe group 70 is smaller than that of the overheating heat exchange pipe group 60, and the heat exchange pipe distribution density of the synergistic pipe group 70 is greater than that of the overheating heat exchange pipe group 60. The synergistic tube group 70 arranged below the overheating heat exchange tube group 60 can not only increase one evaporation process to be beneficial to immersion type heat exchange, but also can enable the thickness of a liquid film on the synergistic tube group 70 to be thinner than that of the overheating heat exchange tube group 60 due to the characteristics of small heat exchange tube diameter and large heat exchange tube distribution density of the synergistic tube group 70, so that the space in the shell 10 can be more fully utilized for arranging the heat exchange tubes, the heat exchange tubes are arranged to the maximum extent, the occupied space of the heat exchanger is saved, the heat exchange area is enlarged, and the heat exchange is fully performed.
It should be noted that the synergistic tube group and the heat exchange tube group are also composed of heat exchange tubes capable of performing evaporation heat exchange.
More preferably, the evaporator further comprises a first drying tube bank 81 and a second drying tube bank 82, and the first drying tube bank 81 and the second drying tube bank 82 are respectively distributed on both sides in the casing 10. By respectively disposing the first drying tube set 81 and the second drying tube set 82 at two sides of the housing 10, a drying process can be added to the air flow channel to make the refrigerant more sufficiently gasified.
Alternatively, in the technical solution of the first embodiment, as shown in fig. 1, the first heat exchange tube group 41, the second heat exchange tube group 42, and the superheated heat exchange tube group 60 are distributed in the middle of the housing 10 in the width direction. More preferably, the first heat exchange tube group 41 is located at an upper middle portion in the case 10, and the second heat exchange tube group 42 is located at a lower middle portion in the case 10. Thus, the arrangement of the heat exchange pipes can be reasonably realized by utilizing the space in the shell 10.
When the technical scheme of the first embodiment is used, after the liquid refrigerant enters the shell 10 through the liquid inlet 21, the liquid refrigerant is uniformly distributed on the first heat exchange tube group 41 by the liquid distributor 30 for evaporation. The remaining liquid refrigerant drips from the first heat exchange tube set 41 to the first liquid equalizing tube set 51, and is evaporated and more uniformly distributed through the first liquid equalizing tube set 51, the refrigerant after being equalized drips to the second heat exchange tube set 42 for evaporation, and the remaining refrigerant drips to the lower portion of the casing 10 and is evaporated by the superheating heat exchange tube set 60 and the efficiency increasing tube set 70, and meanwhile, the efficiency increasing tube set 70 also prevents the refrigerant at the lower portion of the casing 10 from being subjected to air suction and liquid entrainment. The first and second drying tube groups 81 and 82 located at both sides in the housing 10 dry the refrigerant in the airflow channel, so that the refrigerant is more fully gasified. The gaseous refrigerant generated during the evaporation process is discharged through the outlet 22 at the top of the housing 10.
Fig. 2 shows a second embodiment of the evaporator according to the present invention, and the difference between the second embodiment and the first embodiment is that the evaporator further includes a second liquid equalizing tube group 52. The second flow equalization tube set 52 is disposed within the housing 10 and between the liquid distributor 30 and the first heat exchange tube set 41. The pipe diameter of the heat exchange pipe of the second liquid equalizing pipe group 52 is smaller than that of the heat exchange pipe of the first heat exchange pipe group 41, and the distribution density of the heat exchange pipes of the second liquid equalizing pipe group 52 is greater than that of the heat exchange pipes of the first heat exchange pipe group 41. After the refrigerant is distributed from the liquid distributor 30, the refrigerant falls on the second liquid equalizing pipe group 52, is evaporated and better equalized by the second liquid equalizing pipe group 52, so that the refrigerant can be more uniformly distributed on the first heat exchange pipe group 41, and the heat exchange uniformity of the evaporator is improved.
In a more preferred embodiment, the evaporator further comprises a third equalization tube bank 53, the third equalization tube bank 53 being disposed within the shell 10 between the second heat exchange tube bank 42 and the superheating heat exchange tube bank 60. The pipe diameter of the heat exchange pipe of the third liquid equalizing pipe group 53 is smaller than that of the heat exchange pipe of the overheating heat exchange pipe group 60, and the distribution density of the heat exchange pipes of the third liquid equalizing pipe group 53 is greater than that of the heat exchange pipes of the overheating heat exchange pipe group 60. The liquid refrigerant evaporated by the second heat exchange tube set 42 falls on the third liquid equalizing tube set 53, and is evaporated and better equalized, so that the refrigerant can be more uniformly distributed on the superheating heat exchange tube set 60, and the heat exchange uniformity of the evaporator is improved.
As shown in fig. 2, the first heat exchange tube group 41 is located at an upper middle portion in the case 10, and the second heat exchange tube group 42 is located at a lower middle portion in the case 10. Preferably, the first liquid equalizing tube set 51 is divided into two portions, a first portion being adjacent to the first heat exchange tube set 41 and a second portion being adjacent to the second heat exchange tube set 42.
In the second technical solution of the embodiment, after the liquid refrigerant enters the casing 10 through the liquid inlet 21, the liquid refrigerant is uniformly distributed on the second liquid equalizing tube group 52 by the liquid distributor 30, evaporated and equalized by the second liquid equalizing tube group 52, and then falls onto the first heat exchange tube group 41 for evaporation. The remaining liquid refrigerant drops from the first heat exchange tube set 41 to the first liquid equalizing tube set 51, and the refrigerant is evaporated and more uniformly distributed through the first liquid equalizing tube set 51, and the liquid-equalized refrigerant drops to the second heat exchange tube set 42 for evaporation. The unevaporated liquid refrigerant will continue to fall down onto the third liquid-equalizing tube group 53, and be evaporated and equalized by the third liquid-equalizing tube group 53, so that the refrigerant can be more uniformly distributed on the superheating heat exchange tube group 60. The rest of the refrigerant drips and collects at the lower part of the shell 10 and is evaporated by the superheating heat exchange tube group 60 and the synergistic tube group 70, and meanwhile, the synergistic tube group 70 also prevents the refrigerant at the lower part of the shell 10 from generating the phenomenon of air suction and liquid entrainment. The first and second drying tube groups 81 and 82 located at both sides in the housing 10 dry the refrigerant in the airflow channel, so that the refrigerant is more fully gasified. The gaseous refrigerant generated during the evaporation process is discharged through the outlet 22 at the top of the housing 10.
It should be noted that the evaporator solution described above is particularly suitable for use in a falling film evaporator. The first heat exchange tube group 41, the second heat exchange tube group 42, and the superheating heat exchange tube group 60 may be large heat exchange tubes with the same diameter, or large heat exchange tubes with different diameters. The first liquid equalizing tube group 51, the second liquid equalizing tube group 52, the third liquid equalizing tube group 53, the effect enhancing tube group 70, the first drying tube group 81, and the second drying tube group 82 may be small heat exchange tubes having the same diameter or small heat exchange tubes having different diameters.
The invention also provides an air conditioning unit which comprises the evaporator. The air conditioning unit adopting the evaporator can ensure that the liquid refrigerant is more uniformly distributed in the evaporation process, effectively prevents the phenomenon of air suction and liquid entrainment, is favorable for protecting the service life of the compressor, improves the evaporation efficiency of the liquid refrigerant and further improves the operating efficiency of the air conditioning unit.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes may be made to the embodiment of the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
