Description

Technical Field

[0001] This invention relates to the technical field of heat exchange equipment, and more specifically, to a heat exchange device. Background Art

[0002] Heat exchange equipment, such as air conditioners, has temperature regulation functions. During the use of air conditioners, especially in the heating mode of a unitary air conditioner in winter, condensate is generated on the outdoor condenser during heat exchange or high-temperature defrosting and de-icing, causing water to slide down the fins and collect in the chassis. Due to usage requirements, the condensate on the outdoor side of the unitary air conditioner does not require water pipe installation and is not directly discharged or dripped onto the ground or building. When the outdoor ambient temperature is below 0°C, the condensate collected in the chassis will freeze, potentially damaging the high-speed rotating fan blades and the water-repellent rings on the fan blades, causing the air conditioner to malfunction.

[0003] Although some air conditioners on the market now have the technology to melt condensate and supply liquid to the evaporator to form steam, thus achieving humidification, the amount of condensate consumed by the steam is limited, and there is still a problem of condensate needing to be drained.

[0004] As can be seen from the above, the heat exchange equipment in the existing technology has the problem of incomplete condensate treatment. Summary of the Invention

[0016] Furthermore, the baffle plate has a plate-shaped portion and a protrusion arranged in a T-shape. The plate-shaped portion is spaced apart from the outlet, and the protrusion is positioned at one end facing the inlet. At least one end of the plate-shaped portion is spaced apart from the side of the primary cavity to form a flow channel for condensate to flow.

[0017] Furthermore, the heat exchange equipment also includes a filter assembly, which is installed inside the primary chamber.

[0023] Furthermore, the water pump and water collection tank are located on the side of the shell away from the evaporator, with the water pump located at a corner of the shell and the liquid storage tank and water pump located diagonally opposite to the shell.

[0024] Furthermore, at least a portion of the inner surface of the chassis extends downward at an angle away from the evaporator, so that the condensate on the side where the evaporator is located flows back into the water collection tank.

[0055] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0056] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0057] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0058] To address the shortcomings of existing technologies, this invention provides a heat exchange device. This heat exchange device can be used in both industrial and domestic applications to achieve temperature regulation.

[0059] Specifically, the heat exchange equipment is an air conditioner.

[0060] Furthermore, the air conditioner is a modular air conditioner.

[0061] It should be noted that during the use of the heating mode in winter, the outdoor condenser of the integrated air conditioner produces condensate water through heat exchange or high-temperature defrosting and ice melting. The condensate water enters the water collection structure 101 of the air conditioner casing 10 to achieve the effect of collecting condensate water.

[0062] Example 1

[0063] like Figures 1 to 18 As shown, the heat exchange device includes a shell 10, an evaporator 40, and a liquid storage tank 20. The shell 10 has a water collection structure 101 for collecting condensate. The evaporator 40 is disposed inside the shell 10. At least a portion of the water collection structure 101 is connected to the inlet 201 of the liquid storage tank 20. At least one outlet of the liquid storage tank 20 supplies condensate to the evaporator 40 for humidification.

[0064] Specifically, the heat exchange equipment of this application collects the condensate generated during use through the water collection structure 101 and supplies the condensate to the evaporator 40. The evaporator 40 evaporates and consumes the condensate, thereby humidifying the air while consuming the condensate. This application also provides a liquid storage tank 20 to collect excess condensate. The liquid storage tank 20 supplies liquid to the evaporator 40 or collects condensate for centralized discharge, thereby achieving centralized treatment of condensate and avoiding the environmental impact of indiscriminate discharge of condensate.

[0065] Furthermore, the water collection structure 101 includes a water collection tank 1011 for collecting condensate. The water collection structure 101 also includes a water pump 50 and a delivery pipeline 70. The water pump 50 delivers the condensate in the water collection tank 1011 to the liquid storage tank 20 via the delivery pipeline 70.

[0066] It should be noted that when the temperature is too low and the condensate freezes inside the water collection tank 1011 of the water collection structure 101, the heating element 60 installed in the water collection tank 1011 can be used to heat and melt the ice, so that the condensate remains liquid. The water pump 50 is equipped with a float level switch 510. After the heating element 60 heats and melts the ice to form condensate, the float level switch 510 controls the water pump 50 to work. Driven by the water pump 50, the condensate can be transported to the interior of the storage tank 20 through the delivery pipeline 70. The heating element 60 is an electric heater, such as an electric heating wire or an electric heating rod, or other structural components with heating function.

[0067] In this embodiment, the housing 10 has a chassis with a water collection tank 1011 formed on the chassis. The water pump 50 and the water collection tank 1011 are disposed on the side of the housing 10 away from the evaporator 40, and the water pump 50 is located at the corner of the housing 10. The liquid storage tank 20 and the water pump 50 are located diagonally opposite to the housing 10.

[0068] Since the condensate collection tank 1011 is a distance away from the evaporator 40, the condensate is delivered to the storage tank 20 by setting up a water pump 50 and a delivery pipeline 70. The water pump 50 is located at the corner of the housing 10 to provide power for the flow of condensate inside the delivery pipeline 70. The above layout is conducive to the flow of condensate and enhances the collection efficiency of condensate.

[0069] Of course, the water pump 50 is not limited to being located at the corner of the housing 10, but can also be located in other positions inside the housing 10, as long as it can provide power.

[0070] It should be noted that the corner of the housing 10 is the corner formed by the connection of the two sides of the chassis of the housing 10.

[0071] In this embodiment, at least a portion of the inner surface of the chassis extends downward at an angle away from the evaporator 40, so that the condensate on the side where the evaporator 40 is located flows back into the water collection tank 1011.

[0072] like Figures 1 to 4 As shown, a drain valve 1040 is also provided in the water collection tank 1011 to control whether the condensate inside the water collection tank 1011 is discharged to the external environment by controlling the opening and closing of the drain valve 1040.

[0073] Specifically, a rainwater detection device is provided on the housing 10 to detect whether it is raining in the external environment and send a drainage signal when rain is detected. The rainwater detection device is connected to the drainage valve 1040 so that the drainage valve 1040 opens the drainage when it receives the drainage signal.

[0074] Furthermore, the rainwater detection device is a rainwater sensor.

[0075] Furthermore, the water collection tank 1011 has different depth regions. As the condensate in the deep regions is extracted, the condensate in the shallow regions is replenished to the deep regions. The inlet of the delivery pipe 70 is connected to the deepest region of the water collection tank 1011 of the chassis to ensure sufficient condensate transfer.

[0076] like Figure 1 , Figure 2 and Figure 7 As shown, the delivery pipeline 70 includes a first section 701, a second section 702 and a third section 703 connected in sequence. The first section 701 extends along the side of the housing 10, the third section 703 is arranged along the height direction of the housing 10, and the outlet of the third section 703 is located at the top of the storage tank 20.

[0077] Specifically, a segmented delivery pipeline 70 is used to deliver condensate. The first segment 701 and the second segment 702 are bent. Both the first segment 701 and the second segment 702 extend along two adjacent sides of the housing 10. The first segment 701 extends from the pump body toward the evaporator 40, and the second segment 702 extends toward the liquid storage tank 20.

[0078] Furthermore, the specific angle settings of the first segment 701 and the second segment 702 can be adapted according to installation requirements. The first segment 701 and the second segment 702 can be set at right angles.

[0079] Furthermore, the end of the first segment 701 furthest from the second segment 702 is provided with a liquid inlet.

[0080] It should be noted that the first section 701 is used to connect to the water pump 50, the second section 702 is used to transfer liquid to the storage tank 20, and the third section 703 is used to transport the liquid to the top of the storage tank 20. The three-section configuration is used to transfer liquid in order to improve the output efficiency of liquid.

[0081] In this embodiment, the conveying pipe 70 is made of silicone rubber and can be used at a low temperature of -30°C. To ensure that the inside of the pipe does not freeze or become blocked, the outer surface of the conveying pipe 70 is covered with a heat-insulating sponge with a thickness of not less than 9mm.

[0082] like Figures 10 to 15 As shown, the liquid storage tank 20 has a primary chamber 202 and a secondary chamber 203 that are connected to each other. The inlet 201 of the liquid storage tank 20 is connected to the primary chamber 202. The primary chamber 202 is provided with a first outlet 204, which is connected to the primary chamber 202 and is used to supply condensate to the evaporator 40.

[0083] Specifically, the primary cavity 202 is provided with a first outlet 204 that supplies condensate to the evaporator 40. After the condensate enters the primary cavity 202, it can flow from the first outlet 204 to the evaporator 40 to achieve the humidification effect.

[0084] Furthermore, to ensure controllability of the humidification effect, the liquid storage tank 20 also includes a first valve 80, which is located at the first outlet 204 to adjust the on / off state between the primary chamber 202 and the evaporator 40. Controlling the first valve 80 controls whether humidification is applied.

[0085] Furthermore, the distance h between the first outlet 204 and the bottom surface of the primary cavity 202 is 3-5mm, specifically 3mm, 3.5mm, 4mm, 4.5mm, or 5mm.

[0086] It should be noted that the first valve 80 can be remotely controlled to open or close, and can also be manually controlled to open or close. The first valve 80 is a solenoid valve.

[0087] In this embodiment, the volume of the primary chamber 202 is smaller than that of the secondary chamber 203. The secondary chamber 203 is used to store condensate. Two different implementation methods are provided depending on the structure of the liquid storage tank 20.

[0088] like Figures 10 to 15 In the specific embodiment shown, a portion of the liquid storage tank 20 forms a primary cavity 202, and another portion of the liquid storage tank 20 forms a secondary cavity 203. The height of the liquid storage tank 20 forming the secondary cavity 203 is greater than the height of the liquid storage tank 20 forming the primary cavity 202, and the liquid storage tank 20 has a 7-shaped structure.

[0089] Specifically, the volume of the primary cavity 202 is made smaller than that of the secondary cavity 203 by not adjusting the height.

[0090] In a specific embodiment not shown, the primary cavity 202 and the secondary cavity 203 have the same shape, the liquid storage tank 20 is generally rectangular, the bottom of the primary cavity 202 is higher than the bottom of the secondary cavity 203, and the volume of the primary cavity 202 is smaller than the volume of the secondary cavity 203 by the difference in bottom height.

[0091] In this embodiment, the primary cavity 202 and the secondary cavity 203 are arranged in a horizontal direction.

[0092] like Figures 10 to 15 As shown, the liquid storage tank 20 includes a tank body 210, a cover plate 220, and a partition plate 230. The tank body 210 has an outlet, and the cover plate 220 is detachably installed on the top of the tank body 210. The tank body 210 and the cover plate 220 cooperate to form a cavity between them. The inlet 201 is provided on the tank body 210 or the cover plate 220. The partition plate 230 is provided inside the cavity and divides the cavity into a primary cavity 202 and a secondary cavity 203.

[0093] The inlet 201 can be installed on either the cover plate 220 or the housing 210, depending on whether it can allow condensate to enter the interior of the cavity through the inlet 201 under the conveying action of the conveying pipeline 70.

[0094] Specifically, the partition 230 divides the cavity into a primary cavity 202 and a secondary cavity 203, thereby ensuring that condensate first enters the interior of the primary cavity 202. As needed, the condensate is controlled to be supplied to the evaporator 40 from the first outlet 204 of the primary cavity 202, thus preventing condensate from directly entering the interior of the secondary cavity 203.

[0095] Furthermore, the partition 230 is erected within the cavity, and an overflow port 231 is provided at the top of the partition 230. The primary cavity 202 and the secondary cavity 203 are connected through the overflow port 231. Positioning the overflow port 231 at the top of the partition 230 ensures that the outlet is located below the overflow port 231. Of course, the overflow port 231 can also be located at other positions within the partition 230, provided that its position is higher than the outlet.

[0096] In this embodiment, the overflow port 231 is not limited to the method of setting up an overflow port 231 to enable the condensate inside the primary cavity 202 to flow to the secondary cavity 203. Alternatively, an overflow gap can be formed between the top of the partition 230 and the cover plate 220 to allow liquid flow.

[0097] It should be noted that the two methods mentioned above can be set individually or simultaneously.

[0098] like Figures 10 to 15 As shown, to avoid noise and splashing when condensate enters the storage tank 20, the heat exchange equipment also includes a flow-regulating component 90. The inlet 201 is connected to the primary chamber 202 through the flow-regulating component 90. The flow-regulating component 90 is used to guide and slow down the flow of condensate entering through the inlet 201.

[0099] Specifically, the slow-flow component 90 includes a water receiving tank 901, which is formed on the cover plate 220 or the housing 210. The water receiving tank 901 has a water outlet 9011, which is connected to the primary chamber 202. After condensate enters through the inlet 201, it flows along the inner wall of the water receiving tank 901 and flows out through the water outlet 9011. Due to the guiding effect of the water receiving tank 901, the liquid is guided into the interior of the primary chamber 202.

[0100] Furthermore, when the water receiving trough 901 is integrated with the cover plate 220, the water receiving trough 901 is formed by at least a portion of the cover plate 220 recessed into the primary cavity 202, and the opening of the water receiving trough 901 serves as the inlet 201.

[0101] Furthermore, the bottom surface of the water receiving tank 901 is inclined relative to the horizontal plane and has an inclination S of 5°-8°, and the bottom surface of the water receiving tank 901 extends downwards along the direction close to the water outlet 9011. The inclined bottom surface has the effect of preventing water accumulation and allowing condensate to flow smoothly into the primary cavity 202.

[0102] In this embodiment, the tilt angle can be 5°, 6°, 7°, or 8°. A tilt angle that is too small is not conducive to the flow of condensate, while a tilt angle that is too large will affect the buffering effect.

[0103] like Figures 10 to 15As shown, the flow-slowing component 90 also includes a water-blocking rib plate 902, which is disposed inside the primary cavity 202. The water-blocking rib plate 902 is connected to the cover plate 220 or the box 210. At least a portion of the water-blocking rib plate 902 is directly opposite to and spaced apart from the outlet 9011, and a flow gap is formed between the water-blocking rib plate 902 and the outlet 9011, so that the condensate flowing out of the outlet 9011 flows into the primary cavity 202 along the flow gap and the water-blocking rib plate 902.

[0104] Specifically, the condensate flowing out of the outlet 9011 flows into the primary cavity 202 along the flow gap and the baffle plate 902. Under the guidance of the baffle plate 902, the condensate flows along the baffle plate 902 to the primary cavity 202, so as not to produce water flow sound or dripping sound.

[0105] Furthermore, the baffle plate 902 has a plate-shaped portion and a protrusion arranged in a T-shape. The plate-shaped portion is spaced apart from the outlet 9011, and the protrusion is positioned at one end facing the inlet 201.

[0106] Furthermore, the protrusion is positioned directly opposite the outlet 9011.

[0107] In this embodiment, at least one end of the plate-shaped portion is spaced apart from the side of the primary cavity 202 to form a flow channel 903 for the flow of condensate, so that after the buffering effect of the baffle plate 902, the condensate enters the first outlet 204 region of the primary cavity 202 through the flow channel 903.

[0108] like Figures 1 to 15 As shown, the heat exchange equipment also includes a filter assembly 1020, which is disposed inside the primary chamber 202. The filter assembly 1020 divides the primary chamber 202 into a filterable area 2021 and a filterable area 2022. The inlet 201 is connected to the filterable area 2021, and the first outlet 204 and the overflow port 231 of the partition 230 are both connected to the filterable area 2022.

[0109] Specifically, in order to filter impurities in the condensate, a filter assembly 1020 is installed inside the primary chamber 202. The condensate flowing in from the inlet 201 enters the filterable area 2021. The condensate in the filterable area 2021 passes through the filter assembly 1020 and enters the filterable area 2022. The filtered condensate then enters the secondary chamber 203 or the evaporator 40 to purify the condensate.

[0110] Furthermore, the filter assembly 1020 is upright inside the primary cavity 202 so that the filter area 2021 and the filter area 2022 are arranged side by side.

[0111] In this embodiment, the filter assembly 1020 includes at least two uprights 10211, a crossbar 10212, and a filter screen 1022. The at least two uprights 10211 are spaced apart, and two of the uprights 10211 are respectively connected to the side of the partition 230 and the primary cavity 202. The crossbar 10212 is installed on the bottom surface of the primary cavity 202 and connected to the uprights 10211. The crossbar 10212 and the uprights 10211 cooperate to form a filter support 1021, and the filter screen 1022 is installed on the filter support 1021.

[0112] Specifically, the two uprights 10211 are connected by a crossbar 10212 to form a filter support 1021, which is used to support the filter 1022.

[0113] Furthermore, the crossbar 10212 has a preset height, H, which is 8-10mm. The upright 10211 and the crossbar 10212 cooperate to form a U-shaped filter support 1021, and the bottom height H of the filter support 1021 is 8-10mm. The height of the crossbar 10212 can be set to an appropriate height between 8-10mm. After impurities in the condensate inside the filtration area 2021 are stopped by the filter screen 1022 and settle to the bottom, they are then stopped by the crossbar 10212. The crossbar 10212 is used to stop impurities.

[0114] Furthermore, the filter support 1021 is provided with an installation groove, and the filter 1022 is slidably connected to the installation groove. Both the upright 10211 and the crossbar 10212 are provided with slide rails, which cooperate to form a U-shaped slide rail structure, so that the filter 1022 can be inserted and slid onto the filter support 1021 in the vertical direction, which facilitates the installation and removal of the filter and thus achieves the effect of convenient cleaning.

[0115] In this embodiment, the height H of the crossbar 10212 can be 8mm, 8.5mm, 9mm, 9.5mm, or 10mm.

[0116] like Figures 1 to 18 As shown, the heat exchange equipment also includes a liquid level sensing device 1010, which is installed in the secondary chamber 203.

[0117] Specifically, by setting up a liquid level sensing device 1010 to detect the condensate stored inside the secondary cavity 203, the condensate can be processed at regular intervals.

[0118] Furthermore, the heat exchange equipment also includes an indicator device, which is electrically connected to the liquid level sensor 1010. The liquid level sensor 1010 has a liquid level detection end, which is located at the top of the secondary chamber 203. It is used to send an indicator message to the indicator device when it detects that the condensate in the secondary chamber 203 is full. The indicator device then indicates that the liquid storage tank 20 is full.

[0119] The alerting device may be an alarm or similar structure, which will issue an alarm when the condensate in the secondary chamber 203 is full to remind the operator to handle the condensate.

[0120] In this embodiment, the liquid level sensing device 1010 consists of a float and a sensing device. As the condensate inside the secondary cavity 203 gradually increases, the float rises with the liquid level. When the float and the sensing device work together, the sensing device sends a prompt message to the prompting device.

[0121] It should be noted that the liquid level sensing device 1010 can also be a liquid level sensor to detect water level information and send a prompt message to the prompting device after the preset water level is reached.

[0122] like Figures 1 to 18 As shown, the secondary cavity 203 has a third outlet 206. The heat exchange equipment also includes a second valve 1030. The second valve 1030 is located at the third outlet 206 of the secondary cavity 203. The third outlet 206 of the secondary cavity 203 is connected to the water collection tank 1011 of the water collection structure 101 through the second valve 1030, and drains water into the water collection tank 1011.

[0123] Specifically, the second valve 1030 controls the discharge of condensate from the interior of the secondary cavity 203 into the water collection tank 1011, improving controllability so that when it rains outside, the condensate from the interior of the secondary cavity 203 can be directly discharged through the water collection tank 1011.

[0124] It should be noted that the second valve 1030 is a solenoid valve.

[0125] In this embodiment, the secondary chamber 203 also has a second outlet 205 for connecting to the external environment. The second outlet 205 for connecting to the external environment can discharge condensate by disassembling the liquid storage tank 20, or by adding a drain pipe. The liquid storage tank 20 is detachably installed inside the housing 10 so that after disassembling the liquid storage tank 20, the condensate inside the secondary chamber 203 can be centrally discharged through the second outlet 205.

[0126] like Figures 1 to 18As shown, the heat exchange device also includes a drain box 30, which is disposed on top of the evaporator 40 and has a drain chamber communicating with a first outlet 204 of the outlet.

[0127] The drainage chamber includes a transition chamber 302 connected to the first outlet 204 and multiple branch chambers 301 connected to the transition chamber 302. The multiple branch chambers 301 are arranged along the length of the evaporator 40, and each branch chamber 301 has an external communication hole 350 on its cavity wall.

[0128] The drainage box 30 includes a box body 320 and a box cover 310. The box cover 310 covers the box body 320, and the transition cavity 302 and the diversion cavity 301 are disposed inside the box body 320 and the box cover 310.

[0129] Specifically, the drain box 30 has a transition chamber 302 and a diversion chamber 301. The condensate flowing out of the first outlet 204 enters the interior of the transition chamber 302 and then enters the interior of the diversion chamber 301. It then flows to the evaporator 40 through the external connecting hole 350 on the diversion chamber 301. By setting the diversion chamber 301, the liquid can flow evenly to the evaporator 40, which improves the evaporation efficiency and is beneficial to improving the humidification efficiency.

[0130] Furthermore, the drain box 30 is provided with a plurality of first partition plates 330, which are arranged at intervals along the thickness direction of the evaporator 40 to form a transition cavity 302. At least one end of the first partition plate 330 is spaced apart from the inner wall surface of the drain box 30 to form a communication channel. The drain box 30 is also provided with at least one second partition plate 340, which is connected to the first partition plate 330 and the inner wall surface of the drain box 30. The second partition plate 340 divides the interior of the drain box 30 into a plurality of diversion cavities 301.

[0131] The condensate that enters the drain box 30 through the first outlet 204 first enters the transition chamber 302. The transition chamber 302 diverts the condensate so that the condensate flows evenly to the diversion chamber 301.

[0132] Furthermore, the first partition plate 330 and the second partition plate 340 are disposed on the cover 310.

[0133] In this embodiment, the transition cavity 302 formed by multiple first partition plates 330 has multiple sub-cavities, which are connected in a manner. The condensate inside the transition cavity 302 flows into the interior of different diversion cavities 301 through the connecting channels.

[0134] like Figures 1 to 18As shown, two first partition plates 330 are provided. One first partition plate 330 forms a sub-cavity with the side of the drain box 30, communicating with the first outlet 204. Another sub-cavity is formed between the two partition plates 330. The connection port of the two sub-cavities is located in the middle of the other sub-cavity. Two connecting channels are formed between the other first partition plate 330 and the drain box 30 to supply liquid to the two diversion cavities 301. A second partition plate 340 is provided between the other first partition plate 330 and the drain box 30. One end of the second partition plate 340 is connected to the middle of the other first partition plate 330, and the other end of the second partition plate 340 is connected to the middle of the side of the drain box 30, so as to form two diversion cavities 301 of equal size.

[0135] Furthermore, the external connecting hole 350 has a tapered section on the side facing the inside of the drain box 30, and the diameter of the tapered section gradually decreases along the direction towards the outside of the drain box 30. The tapered section of the external connecting hole 350 is conducive to water collection and achieves the technical effect of drainage.

[0136] It should be noted that the external connecting hole 350 also has a circular section, which is connected to the conical section, so that condensate enters the evaporator 40 after passing through the conical and circular sections. The diameter of the circular section is equal to the minimum diameter of the conical section and they are coaxially arranged.

[0137] In this embodiment, to ensure that condensate flows uniformly from the inside of the distribution chamber 301 to the evaporator 40, each distribution chamber 301 is provided with multiple external connecting holes 350. The diameters of the multiple external connecting holes 350 are not completely equal, and the diameter of the external connecting holes 350 near the connection position between the transition chamber 302 and the distribution chamber 301 is smaller than the diameter of the external connecting holes 350 farther away from the connection position between the transition chamber 302 and the distribution chamber 301. After the condensate flows into the inside of the distribution chamber 301, as the flow rate of condensate gradually decreases, to ensure the liquid output, the diameter of the external connecting holes 350 near the connection position between the transition chamber 302 and the distribution chamber 301 is made smaller than the diameter of the external connecting holes 350 farther away from the connection position between the transition chamber 302 and the distribution chamber 301.

[0138] like Figures 1 to 18 As shown, the housing 10 is also provided with a drain channel 102, which is located between the liquid outlet of the evaporator 40 and the water collection tank 1011, so as to realize that the condensate that flows through the evaporator 40 and is not evaporated flows back to the interior of the water collection tank 1011.

[0139] In this process, after the condensate flows to the evaporator 40, some of the unevaporated condensate flows back to the inside of the water collection tank 1011 to achieve the recycling of condensate.

[0140] Example 2

[0141] Unlike Embodiment 1, in this embodiment, the secondary chamber 203 is provided with an outlet for supplying liquid to the evaporator 40.

[0142] Specifically, the condensate is filtered inside the primary chamber 202 and overflows into the secondary chamber 203, and can be supplied to the evaporator 40 through the outlet.

[0143] Example 3

[0144] Unlike Embodiment 1, in this embodiment, both the primary chamber 202 and the secondary chamber 203 are provided with outlets for supplying liquid to the evaporator 40.

[0145] Specifically, multiple outlets are provided to supply condensate to the evaporator 40, thereby increasing controllability and avoiding the problem that the overall condensate flow to the evaporator 40 cannot be achieved when a single outlet is unusable.

[0146] Example 4

[0147] Unlike Embodiment 1, in this embodiment, the filter assembly 1020 is horizontally placed inside the primary cavity 202.

[0148] Specifically, the filter assembly 1020 divides the primary chamber 202 into a filterable area 2021 and a filter area 2022 arranged vertically. After passing through the filter assembly, the condensate enters the interior of the filter area 2022.

[0149] Furthermore, the filter assembly 1020 includes a filter support 1021 disposed on the inner wall surface of the primary cavity 202. The filter support 1021 is used to install and support the filter 1022. The filter 1022 is located above the filter support 1021, which facilitates the removal of the filter 1022.

[0150] It should be noted that, not limited to the above-mentioned arrangement of placing the filter screen 1022 above the filter screen bracket 1021, the filter screen bracket 1021 may also have an installation groove, with the filter screen 1022 installed inside the installation groove. When the filter screen 1022 needs to be replaced, the entire filter screen assembly 1020 can be disassembled and reassembled.

[0151] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0152] The heat exchange equipment of this application collects the condensate generated during use through the water collection structure 101 and supplies the condensate to the evaporator 40. The evaporator 40 evaporates and consumes the condensate, thereby humidifying the air while consuming the condensate. This application also provides a liquid storage tank 20 to collect excess condensate. The liquid storage tank 20 supplies liquid to the evaporator 40 or collects condensate for centralized discharge, realizing centralized treatment of condensate and avoiding the environmental impact of indiscriminate discharge of condensate.
