In one embodiment, the present embodiment provides an evaporative condenser, which is mainly applied to an evaporative condenser unit, and is generally connected in series in an air conditioning system. When the evaporative condenser is used, a high-temperature refrigerant flows through the condenser pipe 3, the high-temperature refrigerant gives off heat outwards through the pipe wall of the condenser pipe 3, the fins 4 are in heat conduction contact with the condenser pipe 3, so that the heat can be transferred to the fins 4, and the fins 4 have large contact area with air, so that the heat dissipation speed can be high.
In order to better describe the structural characteristics of the evaporative condenser in the present embodiment, the whole or partial structure of the evaporative condenser is divided into the middle condensation pipe portion 1 located in the middle of the cross section 6 of the cooling air channel 7 and the outer condensation pipe portion 2 located at the edge portion of the cross section 6 of the cooling air channel 7, which are arranged in sequence along the transverse direction of the cooling air channel, it should be noted that, the middle portion and the edge portion are relative concepts, that is, in one cross section 6, the central portion is the middle portion, and the rest portions are edge portions, and the division of the boundary between the edge portion and the middle portion can be divided according to the actual needs, and is not limited herein, and it is intended to limit at least one group of the middle portion and the edge portion in such a distribution relationship, and does not limit the sizes of the middle portion and the edge portion. Certainly, in practical applications, the boundary corresponding to the boundary of the air inlet or the air supply outlet of the fan 5 in the cooling air channel 7 may be divided, for example, as shown in fig. 7, by the boundary of the air inlet of the fan 5, and as shown in fig. 8, by the boundary of the air supply outlet of the fan 5; of course, the air volume of each cross section of the cooling air channel can be divided according to the air volume, the middle part of the cooling air channel corresponds to the area with large air volume of each cross section, and the edge part of the cooling air channel corresponds to the area with small air volume of the cross section.
The cross section 6, i.e. the transverse cross section, refers to the cross section of the cooling air channel 7 perpendicular to the flowing direction of the cooling air at the current position, because the cooling air channel 7 does not necessarily have to extend linearly, and may also extend in a curve as shown in fig. 7, 8, 9 and 10. Therefore, it can be said that the evaporative condenser is divided into a middle condenser tube portion 1 and an outer condenser tube portion 2, which are sequentially arranged, in the direction perpendicular to the flow direction of the cooling air. In the curved cooling air duct, since the flow direction of the cooling air changes depending on the position of the cooling air duct, the direction perpendicular to the flow direction of the cooling air does not necessarily have to be the same direction for each position of the cooling air duct.
The above-described outside condenser tube portions 4 are generally provided on both sides or all around the middle condenser tube portion 1, such as: in the attached fig. 2, 4 and 5, the two sides of the middle condensing pipe part 1 are provided with outer condensing pipe parts 4; in the attached fig. 6, the outer condenser pipe portions 4 are provided around the middle condenser pipe portion 1; it is of course also possible that three or even more outer condensation duct sections 2 are arranged around the middle condensation duct section 1. Wherein the middle condenser tube portions 1 have condenser tubes 3 and fins 4, and correspondingly, wherein the outer condenser tube portions 2 also have condenser tubes 3 and fins 4. The middle condenser tube portions 1 and the outer condenser tube portions 2 may be condenser tubes having no fins. It should be noted that the middle condensation duct portion 1 and the outer condensation duct portion 2 may belong to the same condensation duct 3, or may belong to different condensation ducts 3.
In the cooling air flowing direction, the cooling efficiency in the unit section of the middle condensation pipe part is at least greater than that in the unit section of the outer condensation pipe part on one side, so that the cooling efficiency in the cooling air flowing direction from one end to the other end corresponding to the unit section of the middle condensation pipe part 1 is at least greater than that in the cooling air flowing direction from one end to the other end corresponding to the unit section of the outer condensation pipe part 2 on one side, namely, the cooling efficiency in the cooling air flowing direction from one end to the other end of the middle condensation pipe part 1 is at least greater than that in the cooling air flowing direction from one end to the other end of the outer condensation pipe part 2 on one side. The cooling efficiency per unit cross section of the condensation duct portion in the cooling air flow direction means a degree of temperature reduction from one end of the condensation duct portion to the other end in the unit cross section in the cooling air flow direction, in which the air of the same temperature and pressure is present in the cross section per unit area. The cooling efficiency in the unit cross section of the middle condensation pipe part 1 is at least greater than that of one side the cooling efficiency in the unit cross section of the outer condensation pipe part 2, the cooling efficiency in the unit cross section of the middle condensation pipe part 1 can be only greater than that of the outer condensation pipe part 2, and the cooling efficiency in the unit cross section of the middle condensation pipe part 1 can be greater than that in the unit cross section of the outer condensation pipe part 2 all around in the flowing direction of cooling air.
One specific expression, as shown in fig. 3, is that the length of the middle condenser tube portion 1 is the same as that of the outer condenser tube portion 2 from one end to the other end in the flow direction of the cooling air, and at this time, the tube distribution density of the middle condenser tube portion 1 is at least greater than that of the outer condenser tube portion 2 on one side, and/or the fin distribution density of the middle condenser tube portion 1 is at least greater than that of the outer condenser tube portion 2 on one side. As shown in figure 1, the tube body distribution density of the middle condensation tube part 1 is at least greater than that of the tube body distribution density of the one outer condensation tube part 2, and as shown in figure 3, the fin distribution density of the middle condensation tube part 1 is at least greater than that of the one outer condensation tube part 2. Another expression, wherein middle part condenser tube portion 1 and outside condenser tube portion 2, body distribution density and fin distribution density are equal, can make along the cooling air flow direction, from one end to the other end middle part condenser tube portion 1 length is longer than outside condenser tube portion 2 length. Of course, the above two forms can be combined according to the requirement.
In the evaporative condenser, when in use, the evaporative condenser is installed in an evaporative condenser unit, the middle condensation pipe part 1 is aligned with the center of a fan 5, the outer condensation pipe part 2 is positioned at the edge part of an air port of the fan 5, even positioned outside the air port radiation surface of the fan 5, so that the air flow passing through the outer condensation pipe part 2 is smaller than the air flow of the middle condensation pipe part 1, in the evaporative condenser, because the cooling efficiency of the unit section of the middle condensation pipe part 1 is at least larger than the cooling efficiency of the unit section of the outer condensation pipe part 2 on one side, the evaporative condenser can correspond to the air flow distribution mode, namely, the air flow flowing into the unit section of the middle condensation pipe part 1 is larger than the air flow flowing into the unit section of the outer condensation pipe part 2 in unit time, and the cooling efficiency corresponding to the middle condensation pipe part 1 is higher than the cooling efficiency of the outer condensation pipe part 2, so as to enable the air outlet, the temperature of the air in the middle condensation duct part 1 and the temperature of the air in the outer condensation duct part 2 may be approximately the same. The cooling effect of the middle part and the edge is close to each other, for example, more coil pipes can be arranged in the middle part, and less coil pipes can be arranged on the outer side, so that the problem of waste of condenser pipelines or waste of refrigerants can be effectively solved.
It should be noted that, in the direction perpendicular to the flow direction of the cooling air, the entire evaporative condenser is divided into the middle condensation duct portion 1 and the outer condensation duct portion 2, and the structural features of the two portions are merely for convenience of description, and are not limited to the two portions being two independent portions. Therefore, the outer condensation pipe part 2 and the middle condensation pipe part 1 are arranged independently, and can be connected in parallel and in series through external connecting pieces to be located in the same air conditioning system, and can also be completely belonged to different air conditioning systems.
It is of course also possible to integrally connect the outer condenser tube sections 2 and the middle condenser tube section 1 so as to communicate with each other through one or more ports. Wherein the multiport intercommunication, specific if a condenser pipe of sampling coils back and forth in the direction with cooling air flow direction looks vertically, and the middle part structure is middle part condenser pipe portion 1, and the outside structure is outside condenser pipe portion 2, a simple mode of coiling, if a condenser pipe coils the back and forth twice in the middle part left and right sides, extends to partly for the outside to one side again to coil once in the outside back and forth, coil twice about reentrant middle part. One of the ports is communicated, and at the moment, a condensing tube can be adopted to be coiled in the middle to form a middle structure and then extend to the outer side to be coiled into an outer side structure.
In a specific embodiment, the evaporative condenser as described above, wherein the cooling efficiency is different, may be further embodied in such a manner that the surface area of the central condensation duct portion 1 in a unit cross section in the flow direction of the cooling air, which is in contact with the air, is larger than the surface area of the outer condensation duct portion 2 in a unit cross section in at least one side. However, in this case, the heat conductivity of the middle condensation duct portion 1 may be made to be the same as that of the outer condensation duct portion 2.
Of course, in another embodiment, the surface area of the middle condenser tube portion 1 in the unit cross section contacting with the air may be equal to the surface area of the one outer condenser tube portion 2 in the unit cross section contacting with the air, but the former cooling efficiency may be higher than the latter cooling efficiency. Specifically, the material of the middle condensation duct portion 1 is different from that of the outer condensation duct portion 2, so that the heat conductivity of the middle condensation duct portion 1 is high, the heat conductivity of the outer condensation duct portion 2 is low, and the case that the surface area of the outer condensation duct portion 2 is larger than that of the middle condensation duct portion 1 may be present. For example, the middle condenser tube portion 1 may be a copper condenser tube portion, and the outer condenser tube portion 2 may be an aluminum condenser tube portion.
Of course, the surface area of the middle condensation duct portion 1 that contacts air per cross section is sufficiently larger than the surface area of the outer condensation duct portion 2 that contacts air per cross section, and the middle condensation duct portion 1 may be an aluminum condensation duct portion and the outer condensation duct portion 2 may be a copper condensation duct portion.
In an embodiment, based on the above embodiment, as shown in fig. 1, the total length of the tubes in the middle condensation duct portion 1 in the same area cross section in the flowing direction of the cooling air can be at least greater than the total length of the tubes in the outer condensation duct portion 2 on one side, so that the middle condensation duct portion 1 has more tubes to participate in the operation, and the number of tubes through which the air passes is greater, thereby cooling the air more intensively. The concrete forms are as described above.
In an embodiment, based on the above embodiment, as shown in fig. 2, the length of the middle condensation duct portion 1 is not less than that of the outer condensation duct portion 2, and the density of the tubes of the middle condensation duct portion 1 is at least greater than that of the tubes of the outer condensation duct portion 2 on one side, so that the length of the middle condensation duct portion 1 can be close to that of the outer condensation duct portion 2, thereby ensuring the space utilization effect.
Middle part condenser tube portion 1 body density is greater than one side at least 2 body densities of outside condenser tube portion can be: in the cooling air flowing direction, the pipe body density of the middle condensation pipe part 1 is at least greater than that of the outer condensation pipe part 2 on one side, so that the pipe bodies of the middle condensation pipe part 1 are more densely distributed than those of the outer condensation pipe part 2 in the cooling air flowing direction, as shown in fig. 1; or in the direction perpendicular to the flowing direction of the cooling air, the pipe body density of the middle condensation pipe part 1 is at least higher than that of the outer condensation pipe part 2 on one side; so that the tubes in the middle condensing tube portion 1 are distributed more densely than the tubes in the outer condensing tube portion 2 in the direction perpendicular to the flow direction of the cooling air, as shown in fig. 2. Of course, both of the above two ways are also possible, as shown in fig. 2 and fig. 1, which are views of the same structure.
In a specific embodiment, in addition to the above-described embodiment, the fin density of the middle condenser tube portions 1 may be made at least higher than the fin density of the one outer condenser tube portions 2 in the cooling air flowing direction, and specifically, when the length of the middle condenser tube portions 1 is not less than the length of the one outer condenser tube portions 2 in the cooling air flowing direction, the fin density of the middle condenser tube portions 1 may be made at least higher than the fin density of the one outer condenser tube portions 2. So that the fin content of the middle condensation tube portions 1 is increased and dense, and the cooling efficiency of the middle condensation tube portions 2 is higher.

Since the evaporative condenser unit of the above embodiment is adopted, please refer to the above embodiment for the beneficial effects of the evaporative condenser unit.
