[0037] Embodiment 1

[0038] In order to solve the problem in the prior art that liquid flowing to the evaporator cannot flow evenly to the evaporator, the utility model provides a heat exchange device.

[0039] Specifically, the heat exchange device is an air conditioner.

[0040] like Figures 1 to 4As shown, the heat exchange device includes a water collecting structure 110, an evaporator 20 and a drainage box 30. The drainage box 30 is arranged on the top of the evaporator 20. The drainage box 30 has an overflow groove 311 extending along the length direction of the evaporator 20 and an overflow hole 313 arranged on at least one side of the overflow groove 311. The overflow hole 313 is spaced apart from and connected to the overflow groove 311. The water collecting structure 110 is connected to the liquid inlet 316 of the drainage box 30 for supplying liquid to the overflow groove 311. The overflow hole 313 is arranged toward the evaporator 20.

[0041] Specifically, the present application adopts an overflow hole 313 that is set on at least one side of the overflow groove 311 and is separated from the overflow groove 311, so that the liquid inside the overflow groove 311 overflows and flows to the overflow hole 313, and the liquid flows to the evaporator 20 through the overflow hole 313, thereby avoiding the problem in the prior art that the flow rate of the overflow hole 313 close to the liquid inlet 316 is greater than the flow rate of the overflow hole 313 far from the liquid inlet 316, resulting in the liquid being unable to flow evenly to the evaporator 20.

[0042] Furthermore, the drainage box 30 is disposed on the top of the evaporator 20 , so that the liquid in the drainage box 30 can flow toward the evaporator 20 under the action of gravity.

[0043] In this embodiment, the overflow groove 311 extends along the length direction of the evaporator 20, so that the liquid inside the overflow groove 311 can flow evenly to the entire evaporator 20, avoiding the problem of not being able to evenly humidify the gas flowing through the evaporator 20. The overflow groove 311 is opened in a direction away from the evaporator 20.

[0044] like Figures 1 to 4 As shown, along a first direction perpendicular to the length direction of the overflow groove 311 , the overflow holes 313 are located on both sides of the overflow groove 311 .

[0045] The first direction is the X direction shown in the figure, that is, the width direction of the drainage box 30 .

[0046] Specifically, overflow holes 313 are provided on both sides of the overflow groove 311 so that the liquid overflowing from the overflow groove 311 can flow to the evaporator 20 through the overflow holes 313 on both sides of the overflow groove 311, thereby increasing the water distribution area, which is beneficial for uniform contact with the fins of the evaporator 20, and further uniformly wetting the gas flowing through the evaporator 20.

[0047] In this embodiment, a plurality of overflow holes 313 are provided, and the plurality of overflow holes 313 are arranged at equal intervals along the length direction of the overflow groove 311 , thereby achieving that the liquid can flow evenly toward the evaporator 20 through the overflow holes 313 along the length direction of the overflow groove 311 .

[0048] Of course, the plurality of overflow holes 313 are not limited to be arranged at equal intervals along the length direction of the overflow groove 311. The plurality of overflow holes 313 may also be arranged at unequal intervals along the length direction of the overflow groove 311, and the distance between two overflow holes 313 may be adaptively set as needed.

[0049] Furthermore, a plurality of overflow holes 313 are provided, and the distance between the upper surface of each overflow hole 313 and the bottom surface of the overflow groove 311 is equal, so as to ensure that the liquid overflowing from the overflow groove 311 can flow into the interior of the plurality of overflow holes 313 in equal amounts. The upper surface of the overflow hole 313 is the surface of the overflow hole 313 away from the opening of the evaporator 20.

[0050] In this embodiment, the opening end of the overflow hole 313 communicating with the overflow groove 311 is located above the groove bottom surface of the overflow groove 311, and the other opening end of the overflow hole 313 is arranged toward the evaporator 20. The overflow hole 313 extends along the height direction of the drain box 30.

[0051] like Figures 1 to 4 As shown, the drainage box 30 also has a water diversion groove 312 which is connected to the overflow groove 311 and is arranged at an angle. The bottom surface of the water diversion groove 312 is located above the bottom surface of the overflow groove 311 along the height direction of the drainage box 30, and at least one overflow hole 313 is arranged inside the water diversion groove 312.

[0052] Specifically, the water dividing groove 312 is connected with the overflow groove 311, and then the overflow groove 311 is connected with the overflow hole 313 through the water dividing groove 312. After the liquid enters the interior of the overflow groove 311, the liquid will partially overflow the overflow groove 311 and flow into the interior of the water dividing groove 312 and flow along the water dividing groove 312. The liquid entering the interior of the water dividing groove 312 flows out through the overflow hole 313 and flows to the evaporator 20.

[0053] Furthermore, the angled water diversion groove 312 can reduce water resistance. In the present embodiment, the drainage box 30 has a liquid inlet 316, and the liquid inlet 316 is connected to one end of the overflow groove 311 along the extension direction of the overflow groove 311. The water diversion groove 312 extends in a direction away from the liquid inlet 316 to achieve an angle A between the extension direction of the water diversion groove 312 and the extension direction of the overflow groove 311, 0°<A≤90°, thereby achieving that the water diversion groove 312 can be set facing the water inlet direction, thereby improving the flow efficiency of the liquid, which is beneficial to improving the cleaning efficiency when the liquid flushes the water diversion groove 312.

[0054] It should be noted that in this embodiment, the angle between the extension direction of the water diversion groove 312 and the extension direction of the overflow groove 311 can also be greater than 90°, but the liquid flow efficiency at this time is lower than the liquid flow efficiency when the angle A satisfies 0°<A≤90°, and thus the problem of low cleaning efficiency occurs when the liquid flushes the water diversion groove 312.

[0055] Furthermore, the overflow hole 313 is disposed on the bottom surface of the water dividing tank 312 to facilitate the liquid inside the water dividing tank 312 to flow completely through the overflow hole 313 to the evaporator 20 .

[0056] Furthermore, a plurality of water diversion grooves 312 are provided, and the plurality of water diversion grooves 312 are arranged at intervals extending in the extending direction of the overflow groove 311. By providing a plurality of water diversion grooves 312, liquid is supplied to the evaporator 20 through the plurality of water diversion grooves 312, thereby improving the uniformity of the liquid flowing to the evaporator 20. The plurality of water diversion grooves 312 may be arranged at equal intervals, which is conducive to further improving the effect of uniform liquid flow; or the plurality of water diversion grooves 312 may be arranged at unequal intervals, which may be adjusted as needed.

[0057] In this embodiment, a plurality of overflow holes 313 are provided inside each water dividing groove 312, and the plurality of overflow holes 313 are arranged at intervals along the extension direction of the water dividing groove 312. By providing a plurality of overflow holes 313, it is beneficial to improve the flow efficiency of the liquid flowing to the evaporator 20, thereby improving the efficiency of humidifying the gas flowing through the evaporator 20.

[0058] like Figures 1 to 4 As shown, the drainage box 30 has a liquid inlet 316, which is connected to one end of the overflow groove 311 along the extension direction of the overflow groove 311. The drainage box 30 also has an openable and closable first sewage outlet 314, which is arranged on the bottom surface of the overflow groove 311 at one end away from the liquid inlet 316.

[0059] Specifically, by setting a first drain port 314 at one end of the overflow trough 311 away from the liquid inlet 316, when the overflow trough 311 needs to be cleaned, the first drain port 314 is opened to increase the flow rate of liquid, so that the solid dirt in the overflow trough 311 can be flushed with liquid and discharged through the first drain port 314, wherein the solid dirt includes sand, dust, sludge, etc.

[0060] Furthermore, the first sewage outlet 314 can be opened and closed by setting a valve to control the opening and closing of the first sewage outlet 314 through the valve, wherein the valve can be an electrically controlled valve electrically connected to the controller or a manually controlled valve.

[0061] Furthermore, the first sewage outlet 314 flows through the first sewage pipe to a sewage collection device for separate collection, such as a sewage collection box.

[0062] In this embodiment, the first sewage outlet 314 is arranged at an end away from the liquid inlet 316, which is conducive to discharging the internal dirt of the overflow groove 311 through the first sewage outlet 314; the first sewage outlet 314 is arranged on the bottom surface of the overflow groove 311 to improve the circulation efficiency of liquid and dirt.

[0063] like Figures 1 to 4 As shown, the drainage box 30 further has a second drain port 315 , which is disposed on a side of the water diversion groove 312 away from the overflow groove 311 , and the second drain port 315 is coplanar with an opening end of the overflow hole 313 .

[0064] Specifically, the second sewage outlet 315 is arranged on a side of the water diversion tank 312 away from the overflow tank 311, so that when cleaning the water diversion tank 312, the solid dirt at the overflow hole 313 can be flushed to the second sewage outlet 315, thereby avoiding the problem of dirt clogging the overflow hole 313 and causing the liquid to be unable to flow evenly to the evaporator 20, wherein the solid dirt is sand, dust, sludge, etc.

[0065] Furthermore, the second sewage outlet 315 flows through the second sewage pipe to a sewage collection device for separate collection, such as a sewage collection box.

[0066] Furthermore, the diameter of the second sewage outlet 315 is greater than the diameter of the overflow hole 313, so that the second sewage outlet 315 can discharge sewage.

[0067] In this embodiment, the second sewage outlet 315 is arranged at one end of the water dividing tank 312 away from the overflow tank 311, so that when the water dividing tank 312 is flushed, the dirt inside the water dividing tank 312 can be completely flushed to the second sewage outlet 315 and discharged through the second sewage outlet 315.

[0068] like Figures 1 to 4 As shown, the drainage box 30 includes a box body 310, a cover plate 320 and a sealing member 330. The box body 310 is provided with a liquid inlet 316, an overflow groove 311, an overflow hole 313, a first sewage outlet 314 and a second sewage outlet 315. The cover plate 320 is covered on the box body 310, and the cover plate 320 abuts against the upper surface where the notch of the water diversion groove 312 is located. The sealing member 330 is arranged between the box body 310 and the cover plate 320. The box body 310 is sealed and connected to the cover plate 320 through the sealing member 330.

[0069] The sealing member 330 is a sealing gasket, and the cover plate 320 is covered on the box body 310 through the sealing member 330 to seal the overflow groove 311 and the overflow hole 313 .

[0070] Specifically, the sealing member 330 may be a sponge or a rubber pad.

[0071] In this embodiment, the box body 310 and the cover plate 320 may be connected by fasteners, such as bolts and screws, or may be fixed by snap fastening.

[0072] like Figures 1 to 4 As shown, the heat exchange equipment also includes a chassis 10, a water tank 40, a water pump 60, a first liquid outlet pipe, a first valve body, a second liquid outlet pipe and a second valve body. The chassis 10 has a water collecting tank, which is a water collecting structure 110. The evaporator 20 is arranged on the chassis 10, the water tank 40 is arranged on the chassis 10, and the water pump 60 is arranged on the chassis 10. The water tank 40 is connected to the water collecting tank through the water pump 60. The water pump 60 is used to provide a driving force for the liquid to flow to the water tank 40. The water tank 40 is connected to the drain box 30 through the first liquid outlet pipe. The first valve body is arranged on the first liquid outlet pipe to adjust the liquid flow rate. The water tank 40 discharges liquid to the outside of the heat exchange equipment through the second liquid outlet pipe. The second valve body is arranged on the second liquid outlet pipe to disconnect the second liquid outlet pipe.

[0073] Specifically, the evaporator 20 is disposed on the bottom plate 10 to collect condensed water on the indoor side; the water tank 40 is used to store liquid to collect liquid, and the liquid collected in the water tank 40 can be directly discharged or flow to the evaporator 20.

[0074] Furthermore, the first valve body has the function of controlling the flow rate, so that when the heat exchange device is in the working mode, the first valve body controls the liquid inside the water tank 40 to supply the liquid to the drain box 30 at a first water inlet flow rate, and the liquid in the drain box 30 flows to the evaporator 20 through the overflow hole 313; when the heat exchange device is in the self-cleaning mode, the first valve body controls the liquid inside the water tank 40 to supply the liquid to the drain box 30 at a second water inlet flow rate, so as to flush the overflow tank 311 and the water distribution tank 312.

[0075] In this embodiment, a second valve body is provided on the second liquid outlet pipe to control whether the liquid in the water tank 40 is discharged to the outside of the heat exchange device through the second valve body.

[0076] In this embodiment, the chassis 10 has an indoor installation area and an outdoor installation area. The evaporator 20, the drain box 30 and the water tank 40 are arranged in the indoor installation area. The heat exchange equipment also includes a condenser 50, a humidity sensor and a controller. The condenser 50 is arranged in the outdoor installation area, and the humidity sensor and the controller are arranged in the indoor installation area. The controller is electrically connected to the evaporator 20, the condenser 50, the humidity sensor, the first valve body and the second valve body.

[0077] The controller and the humidity sensor may be arranged inside the electrical box. The electrical box is arranged on the chassis 10 and is located indoors. The humidity sensor is used to detect the real-time humidity in the room.

[0078] This embodiment also provides a control method for a heat exchange device, where the heat exchange device is the above-mentioned heat exchange device, wherein the heat exchange device has a working mode and a self-cleaning mode.

[0079] like Figure 5 As shown, the control method of the heat exchange equipment includes:

[0080] Receive control instructions;

[0081] Determine and execute working mode or self-cleaning mode according to control instructions;

[0082] When the self-cleaning mode is executed, the second valve body of the heat exchange device is closed, and the water inlet flow rate of the drainage box 30 is adjusted to the second water inlet flow rate to clean the drainage box 30;

[0083] When the working mode is executed, the water inlet flow rate of the drainage box 30 is adjusted to the first water inlet flow rate according to the real-time humidity on the indoor side, and water is supplied to the drainage box 30. At this time, the second valve body is closed, or the first valve body of the heat exchange device is closed and the second valve body is opened. At this time, water is stopped from supplying to the drainage box 30, and the liquid is discharged to the outside of the heat exchange device.

[0084] Specifically, the control instruction can be transmitted to the controller via a remote controller, or can be triggered to the controller via a button, so as to respectively start the working mode or the self-cleaning mode.

[0088] After the actual water level inside the water tank 40 reaches the first preset water level, the overflow tank 311 is started to perform self-cleaning, the first sewage outlet 314 is opened and the water inlet flow rate is set to the second water inlet flow rate;

[0089] When the actual water level inside the water tank 40 drops to the second preset water level, the overflow groove 311 is closed for self-cleaning, the overflow hole 313 is started for self-cleaning, the first drain port 314 is closed, and the liquid is discharged from the second drain port 315 .

[0090] In this embodiment, the first drain outlet 314 is opened, and the overflow tank 311 is first flushed by the second water inlet flow. After the water level inside the water tank 40 drops to the second preset water level, the first drain outlet 314 is closed to allow the liquid inside the drainage box 30 to be discharged to the outside through the second drain outlet 315, so as to clean the overflow tank 311.

[0091] It should be noted that when the liquid inside the water tank 40 is insufficient, the first valve body and the second valve body need to be closed to store liquid inside the water tank 40. The self-cleaning mode starts after the water level inside the water tank 40 reaches the first preset water level.
