[0002] Mobile air conditioners combine the internal and external units of traditional split units into one unit. They are small, portable and mobile, and are widely used in people's daily lives. Because they need to be used on the move, the condensed water produced by refrigeration is not convenient to be discharged in a fixed manner. Therefore, a water pumping device is set up to pump the condensed water onto the condenser to evaporate it, thus achieving the function of no drainage.

[0003] However, the condenser components of existing mobile air conditioners are generally composed of two straight-row condenser components spliced ​​together, and the two sides are connected by condenser side plates. The water pumping wheel is located in the middle of the condenser component, that is, in the closed space formed by the two straight-row condenser components and the side plates on both sides. When pumping water, the water brought up by the water pumping wheel is mainly pumped toward the side plates on both sides, and some water will splash onto the condenser components on both sides, because the water flow of the pumping water needs to hit the high-temperature condenser components to evaporate the water, and hitting the side plates will cause a large loss in water pumping efficiency, resulting in low water pumping efficiency of the water pumping device.

[0004] As can be seen from the above, the prior art has the problem of low water pumping efficiency of mobile air conditioners. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] In order to solve the problem of low water pumping efficiency of mobile air conditioners in the prior art, the present invention provides a heat exchange component and an air conditioner. The air conditioner includes the heat exchange component.

[0029] like Figures 1 to 5 As shown, the heat exchange component includes an evaporator 10, a condenser 20 and a water pumping part 30. The condenser 20 includes an annular main body 21 and a connecting plate 22. The annular main body 21 has a notch section 211. The connecting plate 22 is located at the notch section 211 and is respectively connected to the head and tail ends of the annular main body 21 to form a closed water pumping space 70. The water pumping part 30 includes a water pumping dial 31 and a water pumping motor 32. The water pumping dial 31 is located in the water pumping space 70 and is parallel to the connecting plate 22. The output shaft of the water pumping motor 32 passes through the connecting plate 22 and is drivingly connected to the water pumping dial 31, so as to drive the water pumping dial 31 to rotate.

[0030] The heat exchange component includes an evaporator 10, a condenser 20 and a water pumping part 30. The condenser 20 includes an annular main body 21 and a connecting plate 22. The annular main body 21 has a notch section 211. The connecting plate 22 is located at the notch section 211 and is respectively connected to the head and tail ends of the annular main body 21 to form a closed water pumping space 70. The water pumping part 30 includes a water pumping dial 31 and a water pumping motor 32. The water pumping dial 31 is located in the water pumping space 70 and is parallel to the connecting plate 22. The output shaft of the water pumping motor 32 passes through the connecting plate 22 and is drivingly connected to the water pumping dial 31 to drive the water pumping dial 31 to rotate. In this way, the main body of the condenser 20 is set to be annular and have a notch section 211, and the head and tail ends of the annular main body 21 are connected together through the connecting plate 22 to form a closed water pumping space 70. When pumping water, the water pumping dial 31 of the water pumping part 30 can pump water on both sides onto the high-temperature condenser 20, thereby greatly improving the water pumping evaporation efficiency.

[0031] It can be understood that the closure of the water pumping space 70 is in terms of the circumferential direction of the condenser 20 .

[0032] For existing mobile air conditioners, the condenser is generally composed of two straight-row condenser components spliced ​​together, and the water-pumping motor is on one side of the condenser. Because the condenser component has a certain thickness, and the water-pumping motor needs to be assembled on the bottom shell, the output shaft of the water-pumping motor is longer and there is no support in the middle, resulting in a large motor torque and easy noise.

[0033] In this embodiment, the thickness of the connecting plate 22 is less than the thickness of the annular main body 21. For this application, the connecting plate 22 is equivalent to replacing a part of the annular main body 21, thereby providing installation space for the water pumping member 30, and because the connecting plate 22 has a relatively thin thickness, the length of the output shaft of the water pumping motor 32 is greatly reduced, thereby reducing the radial torque of the output shaft of the water pumping motor 32, reducing noise, and improving user experience.

[0034] In this embodiment, if Figure 6As shown, the length L of the output shaft of the water pumping motor 32 is less than or equal to 28 mm. Specifically, the fin thickness of the existing condenser 20 is generally 25.4 mm, and the length of the output shaft of the water pumping motor 32 is more than 40 mm. In this embodiment, the thickness of the connecting plate 22 is 1 mm, and the output shaft of the water pumping motor 32 can directly pass through the connecting plate 22 and connect with the water pumping wheel 31 without avoiding the condenser 20, so that the length of the output shaft of the water pumping motor 32 is shortened from 42.82 mm to 25.8 mm. The longer the output shaft of the water pumping motor 32, the greater the radial torque to which the water pumping motor 32 is subjected when working, and the easier it is for the bearing inside the motor to generate abnormal noise. The heat exchange component in this embodiment greatly shortens the length of the output shaft of the water pumping motor 32 and reduces the noise of the water pumping motor 32 by reasonably setting the structure of the condenser and the connection form with the water pumping part.

[0035] Reference Figure 4 The actual noise effects of different values ​​of the pumping motor shaft length are shown in Table 1:

[0036] Table 1 Water pump motor noise test results

[0037] Serial number Length of water pumping motor output shaft Noise experience effect 1 42.82mm Obvious buzzing sound 2 35mm The buzzing sound is obvious, with slight improvement 3 30mm A big improvement, but still unacceptable. 4 25.8mm The buzzing sound is slight and acceptable

[0038] It can be seen from Table 1 that the heat exchange assembly of the present application reduces the length of the output shaft of the water pumping motor 32 through reasonable structural design, thereby significantly reducing the noise of the water pumping motor 32.

[0039] like Figures 1 to 5 As shown, the connecting plate 22 is provided with a through hole 221, and a motor sleeve 40 is provided at the through hole 221, and the output shaft of the water pumping motor 32 is passed through the motor sleeve 40. By providing the motor sleeve 40, the support for the water pumping motor 32 can be increased, so that the motor torque can be greatly reduced, and the noise of the water pumping motor 32 can be reduced.

[0040] like Figure 1As shown, the connecting plate 22 has a mounting ear 222 extending in a direction away from the water pumping space 70, and the water pumping motor 32 is connected and fixed to the mounting ear 222. Specifically, the mounting ear 222 extends outward from the bottom of the connecting plate 22, and there are two mounting ears 222, which are respectively located on both sides of the connecting plate 22. The two sides of the water pumping motor 32 have connecting ends, and the connecting ends and the mounting ears 222 are correspondingly arranged up and down and both have mounting holes. The screws pass through the connecting ends and the mounting ears 222 in sequence, so that the water pumping motor 32 is installed and fixed on the connecting plate 22. Through the above arrangement, the water pumping motor 32 is installed and fixed to the connecting plate 22, and the output shaft of the water pumping motor 32 is passed through the motor sleeve 40 on the connecting plate 22, which can ensure the assembly accuracy of the water pumping motor 32, the motor sleeve 40 and the connecting plate 22, and can improve the support stability of the water pumping motor 32, thereby greatly reducing the motor torque and reducing the noise of the water pumping motor 32.

[0041] In this embodiment, the annular main body 21 is in the shape of an annular racetrack, and the notch section 211 is located at a corner of the annular main body 21. Figure 3 and Figure 6 As shown, considering the internal structure design of the air conditioner, the condenser 20 in this embodiment is located at a corner of the bottom shell 50, and the notch section 211 is located near the center of the bottom shell 50, that is, at Figure 3 At the corner of the annular main body 21 in the lower right corner. Figure 3 In the embodiment, the lower long side of the annular main body 21 is cut off, and the arc-shaped transition section between the lower long side and the right short side is also cut off, while the two ends of the connecting plate 22 are respectively connected to the inner side of the lower long side of the annular main body 21 and the end of the right short side. With the above arrangement, the pipelines of the condenser 20 can extend outward at the cut surfaces of the lower long side and the right short side, respectively, and still be within the overall annular range of the condenser 20, without interfering with other components. Furthermore, the space between the pipelines of the two cut surfaces can also be used to accommodate the water pumping motor 32, so that a large part of the water pumping motor 32 is also located within the overall annular range of the condenser 20, which greatly reduces the space occupied by the water pumping motor 32 and facilitates the overall design of the interior of the air conditioner.

[0042] The bottom end layout of the existing condenser 20 needs to be located above the output shaft of the water-pumping motor 32, and a movement gap is reserved to avoid interference between the condenser fins and the output shaft of the water-pumping motor 32. In this way, the height difference between the water-pumping motor 32 and the condenser 20 is large, and water is pumped at the water receiving tray 60 below the condenser 20, resulting in low water pumping efficiency.

[0043] In this embodiment, the through hole 221 is located at the lower part of the connecting plate 22 and has a preset distance from the bottom end of the connecting plate 22. That is to say, the water pumping motor 32 in this embodiment is arranged at the lower part of the connecting plate 22, and the output shaft center of the water pumping motor 32 can be arranged at a position above the bottom end of the condenser 20, so that the relative position of the two can be changed from positive to negative, reducing the height difference between the water pumping wheel 31 and the condenser 20, and greatly improving the water pumping efficiency.

[0044] Through experiments, the data on the influence of the distance H between the output shaft center of the water pumping motor 32 and the bottom end of the condenser 20 on the overall performance and water pumping capacity are as follows, wherein the distance below the bottom end of the condenser 20 of the output shaft center of the water pumping motor 32 is positive, and the distance above the bottom end of the condenser 20 of the output shaft center of the water pumping motor 32 is negative.

[0045] (I) The influence of distance H on the performance of the whole machine:

[0046] By setting different distances H between the output shaft center of the water pumping motor 32 and the bottom end of the condenser 20, various performances of the air conditioner are shown in Table 2.

[0047] Test method: Under the working conditions of 35 / 28.3℃, in the air conditioning cooling mode, set the P1 mode (75Hz-indoor unit 1600r / outdoor unit 1700r), connect the air outlet of the air conditioner to the laboratory wind box, and then measure the various performances of the air conditioner.

[0048] Table 2 Test results of the effect of pumping motor distance H on the performance of the whole machine

[0049]

[0050] It can be seen from Table 2 that as the distance H increases, the overall performance of the air conditioner gradually decreases.

[0051] (II) The influence of distance H on water-flying ability:

[0052] The amount of water remaining in the air conditioner is an important parameter for measuring the water pumping capacity. If there is too much water in the whole machine, it will not only overflow, affecting the user's use, but also trigger the water full protection device, causing shutdown, which greatly reduces the performance of the whole machine. By setting different distances H between the output shaft center of the water pumping motor 32 and the bottom end of the condenser 20, the water pumping capacity of the air conditioner is shown in Table 3.

[0053] Test method: Under the working condition of 30 / 29℃, in the air conditioning cooling mode, set the P1 mode (75Hz-indoor unit 1600r / outdoor unit 1700r). During the test, the whole machine needs to run for 1 hour to keep the whole machine state stable, and then run continuously for 4 hours. After shutting down, weigh the remaining water.

[0054] Table 3 Test results of the effect of pumping motor distance H on pumping capacity

[0055]

[0056] It can be seen from Table 3 that as the distance H increases, the amount of residual water in the air conditioner also increases.

[0057] like Figures 4 to 6 As shown, the present application also provides an air conditioner, including the above heat exchange assembly. Specifically, the notch section 211 of the condenser 20 is connected to the evaporator 10, the compressor, the capillary tube, etc. through a pipeline to form an air conditioning heat exchange system.

[0058] In this embodiment, the air conditioner is a mobile air conditioner.

[0059] like Figures 4 to 6 As shown, the air conditioner further includes a bottom shell 50 and a water receiving pan 60, the water receiving pan 60 is arranged on the bottom shell 50, and the heat exchange assembly is located above the water receiving pan 60, so that the condensed water generated by the evaporator 10 is collected by the water receiving pan 60 and flows to the water pumping member 30. Specifically, a raised platform structure is provided on the water receiving pan 60 to support the condenser 20 and the evaporator 10. During cooling, the condensed water generated by the evaporator 10 is collected by the water receiving pan 60 and flows to the bottom of the condenser 20.

[0060] In this embodiment, there is a gap between the water receiving pan 60 and the bottom shell 50, and a support rib is provided at the gap. Specifically, there are multiple support ribs, and the multiple support ribs are arranged at intervals in the gap. In this way, the water receiving pan 60 and the bottom shell 50 are equivalent to air insulation, which prevents the coldness of the condensed water generated by the evaporator 10 from being transmitted to the bottom of the bottom shell 50 and forming condensation at the bottom of the bottom shell 50.

[0061] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: by setting the heat exchange component including the evaporator 10, the condenser 20 and the water pumping member 30, the condenser 20 includes the annular main body 21 and the connecting plate 22, the annular main body 21 has a notch section 211, the connecting plate 22 is located at the notch section 211 and is respectively connected to the front and rear ends of the annular main body 21 to form a closed water pumping space 70, the water pumping member 30 includes a water pumping wheel 31 and a water pumping motor 32, the water pumping wheel 31 is located in the water pumping space 70 and is parallel to the connecting plate 22, the output shaft of the water pumping motor 32 passes through the connecting plate 22 and is drivingly connected to the water pumping paddle wheel 31, and is used to drive the water pumping paddle wheel 31 to rotate. In this way, by setting the main body of the condenser 20 to be annular and having a notch section 211, and then connecting the head and tail ends of the annular main body 21 together through the connecting plate 22, a closed water pumping space 70 is formed, so that the water pumping paddle wheel 31 of the water pumping member 30 can pump water on both sides onto the high-temperature condenser 20 when pumping water, thereby greatly improving the water pumping evaporation efficiency.
