[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] See Figures 1 to 9, according to an embodiment of the present utility model, a heat exchange structure is provided, including: a heat exchange tube group 1, the heat exchange tube group 1 includes fins 11 and heat exchange tubes 12 penetrating through the fins 11; a return air passage 2 for air flow is provided below the heat exchange tubes 12; a water storage component 3 is located in the return air passage 2, the water storage component 3 includes a water storage tank 33, and the water storage tank 33 is arranged corresponding to the fins 11 so that the condensed water on the fins 11 flows into the water storage tank 33; a switching mechanism 4, the switching mechanism 4 has a closed state and an open state; when the switching mechanism 4 is in the closed state, the switching mechanism 4 seals the water storage tank 33 so that the condensed water accumulates in the water storage tank 33; when the switching mechanism 4 is in the open state, the switching mechanism 4 opens the water storage tank 33 so that the condensed water in the water storage tank 33 flows out. With the above arrangement, a condensed water storage component 3 is added below the heat exchange tube group 1, and the water storage tank 33 of the water storage component 3 and the return air passage 2 cross and exist below a common heat exchanger. In this way, when the flowing air passes through the return air passage 2, it can pass through the water storage tank 33 to cool the air flow with the condensed water in the water storage tank 33, thereby effectively utilizing the cold quantity of the condensed water and solving the technical problem that the condensed water generated by the air conditioner heat exchanger is not effectively utilized.

[0034] Specifically, the water storage component 3 of this embodiment is a hydrophilic aluminum sheet structure (other materials are also available) with the same material as the fins, used to separate the air and water channels, and utilize the condensed water generated by the upper heat exchange tube group 1 for heat exchange, without the need to add copper tubes and refrigerant to provide cold quantity.

[0035] See Figure 1 , in the heat exchange structure of this embodiment, there are at least two fins 11, and the at least two fins 11 are arranged at intervals along a preset direction; a water storage tank 33 is provided below each of two adjacent fins 11. In this way, the condensed water is evenly distributed in the return air passage 2, thereby improving the heat exchange efficiency.

[0036] In the heat exchange structure of this embodiment, see Figure 3 , the water storage component 3 includes: a first water storage plate 31 and a second water storage plate 32, the first water storage plate 31 and the second water storage plate 32 are respectively in contact with two adjacent fins 11; the water storage tank 33 is located between the first water storage plate 31 and the second water storage plate 32. In this way, it is beneficial for the condensed water on the fins 11 to flow into the water storage tank 33, thereby facilitating the collection of condensed water and preventing the condensed water from being exposed.

[0037] See Figure 3 , in the heat exchange structure of this embodiment, along the direction in which the fins 11 approach the water storage tank 33, the first water storage plate 31 and the second water storage plate 32 gradually approach each other. In this way, the first water storage plate 31 and the second water storage plate 32 form a V-shaped structure, which is beneficial for the condensation of condensed water, thereby facilitating the control of the amount of condensed water in the water storage tank 33.

[0038] See Figures 4 to 7, in the heat exchange structure of this embodiment, the switch mechanism 4 includes: a first water baffle 41 and a second water baffle 42, and both the first water baffle 41 and the second water baffle 42 are movably arranged; wherein, when the switch mechanism 4 is in the closed state, the first water baffle 41 abuts against one end of the first water storage plate 31 and one end of the second water storage plate 32, and the second water baffle 42 abuts against the other end of the first water storage plate 31 and the other end of the second water storage plate 32, thereby blocking the water storage tank 33; when the switch mechanism 4 is in the open state, the first water baffle 41 is separated from the first water storage plate 31 and the second water storage plate 32, and the second water baffle 42 is separated from the first water storage plate 31 and the second water storage plate 32, thereby opening the water storage tank 33. With the above arrangement, when it is necessary to collect condensed water, the first water baffle 41 and the second water baffle 42 block the water storage tank 33 from both ends of the water storage tank 33, so that the condensed water accumulates in the tank. When the condensed water accumulates too much, the first water baffle 41 and the second water baffle 42 are controlled to open the water storage tank 33, thereby discharging the condensed water. The above structure is simple and easy to control.

[0039] See Figure 1 , in the heat exchange structure of this embodiment, there are at least two water storage components 3, and the at least two water storage components 3 are arranged at intervals; there are at least two first water baffles 41, and the at least two first water baffles 41 are arranged in one-to-one correspondence with the at least two water storage components 3; there are at least two second water baffles 42, and the at least two second water baffles 42 are arranged in one-to-one correspondence with the at least two water storage components 3. In this way, the volume of the first water baffle 41 and the second water baffle 42 can be reduced, which is convenient for driving the first water baffle 41 and the second water baffle 42 to move.

[0040] In the heat exchange structure of this embodiment, see Figures 4 to 7 , the switch mechanism 4 includes: a first driving motor 5, a first driving rod 51 is arranged on the output shaft of the first driving motor 5, and the first driving rod 51 is connected to at least two first water baffles 41, so as to drive at least two first water baffles 41 to move through the first driving rod 51; a second driving motor, a second driving rod is arranged on the output shaft of the second driving motor, and the second driving rod is connected to at least two second water baffles 42, so as to drive at least two second water baffles 42 to move through the second driving rod. In this way, by arranging one motor, it is possible to drive multiple water baffles to move, without occupying space and without blocking the air flow.

[0041] Embodiment 1:

[0042] See Figure 4 , Figure 5 , in the heat exchange structure of this embodiment, the first driving motor 5 is used to drive the first driving rod 51 to move, thereby driving the first water baffle 41 to move.

[0043] Embodiment 2:

[0044] See Figure 6 , the first driving motor 5 is used to drive the first driving rod 51 to rotate, so as to wind or unwind the first water baffle 41 by the first driving rod 51.

[0045] For the above two control methods, the water baffle is controlled as a whole, with a simple structure and high efficiency.

[0046] Embodiment Three:

[0047] See Figures 7 to 9 , in the heat exchange structure of this embodiment, the switch mechanism 4 includes: a floating plate 43 movably arranged in the water storage tank 33; a first support shaft 44, one end of the first support shaft 44 is rotatably connected to the floating plate 43 relatively, and the other end of the first support shaft 44 is movably connected to the first water baffle 41 relatively; a second support shaft 45, one end of the second support shaft 45 is rotatably connected to the floating plate 43 relatively, and the other end of the second support shaft 45 is movably connected to the second water baffle 42 relatively; wherein, the floating plate 43 moves with the change of the water level in the water storage tank 33, so as to drive the first support shaft 44 and the second support shaft 45 to move. With this setting, it can be controlled according to the amount of condensed water in each water storage tank 33. When the amount of condensed water in the water storage tank 33 is not much, it will not be discharged, thus ensuring the heat exchange effect.

[0048] See Figures 7 to 9 , in the heat exchange structure of this embodiment, the first support shaft 44 includes a first support rod 441 and a first ejector rod 442. One end of the first support rod 441 is rotatably connected to the floating plate 43 relatively, and the other end of the first support rod 441 is rotatably connected to the first ejector rod 442 relatively; the end of the first ejector rod 442 far from the first support rod 441 is rotatably connected to the first water baffle 41 relatively, and the first ejector rod 442 is movably connected to the first water baffle 41 relatively; and / or, the second support shaft 45 includes a second support rod 451 and a second ejector rod 452. One end of the second support rod 451 is rotatably connected to the floating plate 43 relatively, and the other end of the second support rod 451 is rotatably connected to the second ejector rod 452 relatively; the end of the second ejector rod 452 far from the second support rod 451 is rotatably connected to the second water baffle 42 relatively, and the second ejector rod 452 is movably connected to the second water baffle 42 relatively. In this way, the first water baffle 41 and the second water baffle 42 move flexibly and are convenient to control. Moreover, when the first water baffle 41 and the second water baffle 42 close the water storage tank 33, the first support shaft 44 and the second support shaft 45 can tighten the first water baffle 41 and the second water baffle 42, so that the first water baffle 41 and the second water baffle 42 are closed, ensuring the sealing effect.

[0049] In the heat exchange structure of this embodiment, see Figure 1The heat exchange structure further includes a water receiving pan 6, a water receiving plate 61 is arranged on the periphery of the water receiving pan 6, and the water receiving plate 61 forms a water receiving groove 62; the switch mechanism 4 is arranged in the water receiving groove 62. In this way, when the condensed water is exposed, the water receiving pan 6 can prevent the condensed water from further leaking out.

[0050] The air conditioner of this embodiment includes a heat exchange structure, and the heat exchange structure is the heat exchange structure mentioned above.

[0051] The heat exchange structure of this embodiment is composed of fins 11 and heat exchange tubes 12, but the structure is different from that of conventional fin heat exchangers. The heat exchanger structure can be divided into two parts, the upper part, which is the same as the conventional fin heat exchanger, and is composed of heat exchange tubes 12 and fins 11. The fins 11 are parallel and equidistantly sleeved on the heat exchange tubes 12. The fins 11 can be flat, corrugated, or louvered. The lower part is a V-shaped fin 11 structure. A V-shaped fin 11 structure is arranged under every two or more upper fins 11 for water storage. The specific structure is shown in FIG. Figure 3 , can be formed by bending a piece of fin 11, or can be formed by combining the upper and lower parts separately. A cavity is set at the connection between the upper end of the V-shaped structure and the conventional fin 11 to receive the condensed water on the outside of the fin 11 (to prevent the condensed water from flowing into the return air channel 2), forming a condensed water storage tank 33, without the need for the heat exchange tube 12 sleeve, the fin 11 can be in the form of a flat sheet or a corrugated sheet (sealed without holes to store water), etc., the front and rear of the V-shaped structure are provided with a first water baffle 41 and a second water baffle 42 whose switches are controlled by a stepper motor, and the shapes of the first water baffle 41 and the second water baffle 42 are also V-shaped structures, which can be controlled by a stepper motor ( Figures 4 to 6 ) or baffle switch mechanism ( Figure 7 ) control. Figure 4 As shown, when the water storage tank 33 of the fin 11 is full and needs to be drained, the stepper motor starts, and the V-shaped baffle moves left and right or forward or shrinks in the form of a roller blind. A timer switch can be set, and the interval time is determined by the dehumidification amount (i.e., the amount of condensed water). The opening time is based on ensuring that the condensed water is completely discharged. After the condensed water is discharged, it moves back to the original position to collect the condensed water again. The baffle switch mechanism is controlled as follows Figures 7 to 9 As shown, the mechanism is placed in a water tank 33. When there is no condensed water in the channel, the floating plate 43 falls to the position as shown in FIG. Figure 8 The position shown is stuck by the left and right V-shaped structures. When condensed water accumulates in the channel, the floating plate 43 floats up and drives the support shaft to open the front and rear first water baffle plate 41 and the second water baffle plate 42, as shown in FIG. Figure 9 As shown, when the water is fully stored, the baffle opening angle is the largest, and condensed water flows out from the front and back. When the water level drops, the floating plate 43 drops and drives the support shaft to close the front and rear baffles, and water storage starts again.

[0052] The utility model can be applied to high humidity areas and places with large dehumidification needs. The specific implementation process is as follows:

[0053] During the cooling operation, 7°C cold water flows through the upper heat exchange tubes 12. The heat exchange tubes 12 have good thermal conductivity, and the cold energy will be transferred to the fins 11 sleeved on the heat exchange tubes 12. The hot and humid air is cooled and dehumidified after passing through the upper conventional fin 11 heat exchanger, generating a large amount of condensed water. The condensed water flows down along the fins 11 due to gravity to the lower condensate storage tank 33 and gradually fills up. The lower condensate storage tank 33 is only composed of seamless fins 11 without heat exchange tubes 12. The storage tank 33 and the return air duct 2 exist alternately. There are return air ducts 2 on both sides of a storage tank 33. The return air exchanges heat with the wall surface of the condensate storage tank 33, i.e., the water storage component 3, and the cold energy comes from the condensed water. A stepper motor inductor can be arranged on the water level line of the storage tank 33. When the storage tank 33 is full, the inductor gets an induction and the stepper motor starts to work. The stepper motor controls the V-shaped baffle to move left and right or contract in the form of a rolling curtain. The front and back of the storage tank 33 are opened for drainage, and at the same time, the return air is used as auxiliary power for drainage. The stepper motor is set to close the V-shaped baffle regularly, and the time is determined by the drainage time required. Alternatively, a baffle switch mechanism can be arranged in a certain storage tank 33, and the baffle is opened and closed through a floating plate and a support shaft.
