Description

Technical Field

[0001] This application relates to the field of air conditioning heat dissipation technology, and in particular to a water-cooled heat dissipation device for an integrated air conditioning unit based on a box-type spray system. Background Technology

[0002] An all-in-one air conditioning unit is an air conditioning device that integrates cooling and heating functions, widely used in homes, offices, and other places. It achieves heat transfer and regulates indoor temperature by circulating refrigerant between the evaporator and condenser. During the cooling process, the refrigerant absorbs indoor heat and vaporizes in the evaporator, then is compressed into a high-temperature, high-pressure gas by the compressor, releases heat in the condenser, and finally returns to the evaporator through a throttling device, completing one refrigeration cycle.

[0003] In traditional integrated air conditioning units, condenser heat dissipation primarily relies on airflow. The condenser is typically installed outdoors, and a fan blows surrounding air across its fins, carrying away the heat released by the refrigerant. However, this heat dissipation method has limitations. In high-temperature environments, the ambient air temperature is already high, reducing the temperature difference between the condenser and the air, thus decreasing heat dissipation efficiency. Especially in hot regions or during peak summer temperatures, poor condenser heat dissipation leads to increased refrigerant condensation temperature, increased compressor load, and consequently, a lower coefficient of performance (COP) and higher energy consumption for the integrated air conditioning unit.

[0038] The present application will be further described below with reference to the accompanying drawings, but the scope of protection of the present application is not limited to the following description.

[0039] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0040] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0041] Air conditioning units produce condensate during the cooling process. Condensate is formed when water vapor in the indoor air condenses on the surface of the evaporator. In current air conditioning unit designs, condensate is typically discharged directly outdoors through a drain pipe. While this method is simple, it doesn't fully utilize the potential value of condensate. Condensate has a relatively low temperature; if properly utilized, it can serve as an additional cooling resource, further improving the condenser's heat dissipation efficiency. However, most current air conditioning units lack a design for collecting and utilizing condensate, resulting in resource waste.

[0042] After the air conditioner is turned off, water may remain in the condensate collection device or drain pipe. This water can easily become damp, leading to corrosion and affecting the lifespan of the air conditioner. Furthermore, in a humid environment, this water can easily breed bacteria, polluting the internal environment of the air conditioner and potentially negatively impacting air quality and human health. For example, bacterial growth may result in the air blown out by the air conditioner containing a large number of bacteria, causing respiratory illnesses and other health problems.

[0043] This application provides a water-cooled heat dissipation device for an integrated air conditioning unit based on a box-type spray system, used to improve the energy efficiency ratio of the integrated air conditioning unit and prevent water accumulation. The following will be combined with... Figures 1 to 5 This embodiment details the implementation of a water-cooled heat dissipation device for an integrated air conditioning unit based on a box-type spray system.

[0044] like Figure 1 As shown in the figure, this application embodiment provides a water-cooled heat dissipation device for an integrated air conditioner based on a box-type spray system. The water-cooled heat dissipation device for the integrated air conditioner based on a box-type spray system in this embodiment includes: an evaporator water collection box 10, a chassis water collection box 30, a spray box 20, and a water pump 40.

[0045] Wherein: the evaporator water collection box 10 is installed below the evaporator 1 of the air conditioner unit to collect the condensate produced by the evaporator 1; the chassis water collection box 30 is set at the bottom of the condenser 2 of the air conditioner unit, and the condensate collected by the evaporator water collection box 10 flows into the chassis water collection box 30 through a water guide pipe; the spray box 20 is installed on the top of the condenser 2, and the water pump 40 is installed in the chassis water collection box 30 to draw the condensate in the chassis water collection box 30 into the spray box 20; the spray box 20 is provided with a plurality of drip holes 201, and the condensate drips onto the condenser 2 through the drip holes 201 and evaporates.

[0046] In the water-cooled heat dissipation device of the integrated air conditioner based on box-type spray in this embodiment, the condensate generated by the evaporator 1 flows sequentially into the evaporator water collection box 10 and the chassis water collection box 30. The water pump 40 starts to work and pumps the condensate in the chassis water collection box 30 to the spray box 20. The condensate in the spray box 20 flows out through the drip hole 201 and drips onto the condenser 2 and evaporates. This makes full use of the condensate naturally generated by the integrated air conditioner during the cooling process, so that the condensate is sprayed onto the condenser 2 fully and evenly, which significantly improves the energy efficiency of the integrated air conditioner unit.

[0047] The structure of the water-cooled heat dissipation device of the integrated air conditioning unit based on box-type spraying in this embodiment will be described in detail below.

[0048] In this embodiment, the main function of the evaporator water collection box 10 is to collect the condensate generated on the surface of the evaporator 1 during the operation of the air conditioner and to utilize the condensate for energy efficiency.

[0049] In addition, the evaporator water collection box 10 can collect condensate water and prevent condensate water from dripping randomly, causing water to accumulate inside the air conditioner or drip onto the outside. This helps to keep the inside of the air conditioner dry and clean, and also avoids the condensate water from affecting the surrounding environment.

[0050] The evaporator water collection box 10 is installed directly below the evaporator 1 of the air conditioner unit, in order to collect the condensate generated by the evaporator 1 during the cooling process to the greatest extent.

[0051] In this embodiment, the evaporator water collection box 10 is in direct contact with the bottom edge of the evaporator 1, and the tight fit ensures that the condensate can flow smoothly into the water collection box. This contact method can prevent condensate from leaking out from gaps.

[0052] In other embodiments, the evaporator water collection box 10 is fixed below the evaporator 1 by a support or other structure, maintaining a certain distance from the evaporator 1, but still effectively collecting condensate. The support not only supports the water collection box but also ensures its positional stability, preventing it from shifting due to vibration or other factors during air conditioning operation.

[0053] In addition, to ensure a secure connection between the evaporator water collection box 10 and the evaporator 1, the evaporator water collection box 10 can be fixed to the air conditioner housing below the evaporator 1 or to a component connected to the evaporator 1 using clips or screws. This fixing method facilitates the installation and removal of the evaporator water collection box 10, while also withstanding certain external forces to ensure its stability during long-term use.

[0054] In this embodiment, the main body of the evaporator water collection box 10 is a water collection tank with a certain depth and area. Its shape is not limited to rectangle, square, or circle, etc. The specific shape and size are matched with the size of the internal space of the air conditioning unit and the shape and size of the evaporator 1 to ensure that condensate can be collected sufficiently. The depth of the evaporator water collection box 10 is generally sufficient to accommodate a certain amount of condensate to prevent condensate from overflowing.

[0055] To ensure that the condensate flows smoothly to the drain outlet, in this embodiment, the bottom of the evaporator water collection box 10 is sloping towards the drain outlet. This utilizes gravity to accelerate the flow of condensate and improve drainage efficiency. For example, the bottom of the evaporator water collection box 10 has a sloping structure with all four sides inclined towards the drain outlet in the center, allowing the condensate to quickly collect at the drain outlet.

[0056] The drain outlet is a crucial part for draining condensate from the evaporator water collection box 10. It is located at the lowest point of the evaporator water collection box 10 to ensure that the condensate can be completely drained. The drain outlet can be circular, square, or inverted V-shaped, among others. An inverted V-shaped drain outlet is preferred to allow the condensate to flow out more smoothly and reduce the possibility of blockage.

[0057] In some embodiments, the evaporator water collection box 10 is equipped with a filter device, such as a filter screen or filter cotton, at the drain outlet to filter impurities and dust in the condensate, preventing these impurities from entering the drain pipe and causing blockage. The filter device needs to be cleaned or replaced regularly to maintain its filtering effect.

[0058] In one implementation of this embodiment, a side water collection box 50 is connected between the evaporator water collection box 10 and the chassis water collection box 30 via a water pipe; the side water collection box 50 is fixed below one end of the evaporator water collection box 10. The condensate produced by the evaporator 1 flows sequentially into the evaporator water collection box 10, the side water collection box 50, and the chassis water collection box 30. The water pump 40 starts working to pump the condensate in the chassis water collection box 30 to the spray box 20. The condensate in the spray box 20 flows out through the drip hole 201 and drips onto the condenser 2 and evaporates.

[0059] In this embodiment, the spray box 20 is installed on top of the condenser 2 to collect the condensate produced by the evaporator 1, allowing the condensate to drip onto the condenser 2 and evaporate. The condenser is fixed inside the air conditioning unit by the condenser 2 fixing plate 3. The main function of the condenser 2 is to cool the refrigerant from a gaseous state to a liquid state, releasing heat. If the condensate produced by the evaporator 1 drips onto the condenser 2, the condensate will absorb heat as it evaporates on the surface of the condenser 2, thus playing an auxiliary role in heat dissipation. This can improve the heat dissipation efficiency of the condenser 2 to a certain extent, especially when the ambient temperature is high. Moreover, by recycling the condensate produced by the evaporator 1, the demand for additional cooling water can be reduced, thereby saving water resources.

[0060] In this embodiment, the spray box 20 is connected to the evaporator water collection box 10 via a pipe for transporting condensate. The pipe material should have good corrosion resistance and sealing properties to prevent condensate leakage.

[0061] The spray box 20 is installed on the top of the condenser 2, which ensures that the condensate can drip evenly onto the surface of the condenser 2. The spray box 20 can be fixed to the top of the condenser 2 by means of brackets, screws or clips to ensure its stable position and prevent it from shifting due to vibration or external force.

[0062] Figure 2 This diagram shows the assembly of the spray box 20 and the condenser 2 in the water-cooled heat dissipation device of the integrated air conditioner based on a box-type spray system described in this embodiment of the application. Figure 2 As shown, in one implementation of this embodiment, the spray box 20 is fixed to the top of the condenser 2 by a positioning plate 204; the positioning plate 204 includes a middle plate and two locking ends disposed at both ends of the middle plate to lock the spray box 20 on both sides of the condenser 2.

[0063] The spray box 20 is fixed to the top of the condenser 2 by the positioning pressure plate 204, ensuring the stability and firmness of the spray box 20. The intermediate pressure plate is the main part of the positioning pressure plate 204. It is located in the middle of the spray box 20 and serves to support and fix the spray box 20. The intermediate pressure plate contacts the top of the spray box 20 and ensures its positional stability by pressing the spray box 20. The positioning pressure plate 204 is made of metal or high-strength plastic material to ensure sufficient strength and durability.

[0064] In this embodiment, the locking ends are located at both ends of the intermediate pressure plate and are used to lock the two sides of the spray box 20 onto the condenser 2, enhancing the fixing effect of the spray box 20. The locking ends are hook-shaped or snap-fit-shaped, which can fit tightly with the sides of the spray box 20 to ensure that the spray box 20 will not loosen or shift. Similar to the intermediate pressure plate, the locking ends are also made of metal or high-strength plastic material to ensure sufficient strength and durability.

[0065] The spray box 20 is securely fixed to the top of the condenser 2 by the pressing action of the intermediate pressure plate and the locking action of the locking end. This fixing method not only ensures that the spray box 20 will not shift or loosen during operation, but also facilitates the installation and disassembly of the spray box 20, making maintenance and upkeep easier.

[0066] Figure 3 The diagram shown is a structural schematic of the spray box 20 in the water-cooled heat dissipation device of the integrated air conditioning unit based on box-type spraying, as described in an embodiment of this application. Figure 3 As shown, in one implementation of this embodiment, to ensure that the condensate is sprayed onto the condenser 2 sufficiently and evenly, the drip holes 201 in the spray box 20 include at least two different hole sizes. The distribution of the drip holes 201 ensures that the condensate can evenly cover the entire surface of the condenser 2, thereby improving the heat dissipation effect.

[0067] Large-diameter drip holes provide a larger water flow, ensuring that condensate drips quickly onto the condenser 2, making them suitable for areas with high condensate production. In this embodiment, the large-diameter drip holes are located near the water inlet 203 of the spray box 20. Small-diameter drip holes provide a smaller water flow, ensuring that condensate is evenly distributed to all corners of the condenser 2, making them suitable for areas with low condensate production.

[0068] In this embodiment, the small-diameter drip holes are positioned away from the water inlet 203 of the spray box 20. Drip holes 201 with different diameters can provide different water flow rates and drip frequencies, allowing condensate to form a more uniform water film on the surface of the condenser 2, increasing the evaporation area and improving heat dissipation efficiency. By setting drip holes 201 with different diameters, condensate can be more evenly distributed to all parts of the condenser 2, avoiding situations where some areas have excessive condensate while others have insufficient condensate.

[0069] In addition, if the surface area of ​​the condenser 2 is large, multiple large-diameter drip holes can be set in the central area of ​​the spray box 20, and multiple small-diameter drip holes can be set in the edge area to ensure uniform distribution of condensate.

[0070] The drip holes 201 of different sizes are arranged in an array, and the drip holes 201 of different sizes are arranged in order from small to large or from large to small. Preferably, the drip holes 201 of the same size are arranged in a linear pattern, and the drip holes 201 of the same size are arranged in one or more rows of linear patterns.

[0071] For example, in this embodiment, three different sizes of drip holes 201 are provided: drip holes 201 with a diameter of 1.5 mm, drip holes 201 with a diameter of 2.0 mm, and drip holes 201 with a diameter of 3.0 mm. Among them, multiple drip holes 201 with a diameter of 1.5 mm are arranged in a line, then drip holes 201 with a diameter of 2.0 mm are arranged in a line, and finally drip holes 201 with a diameter of 3.0 mm are arranged in two lines.

[0072] The drip hole 201 may become clogged with impurities in the condensate, affecting the distribution of condensate and heat dissipation. A filter device, such as a filter screen or filter cotton, can be installed inside the spray box 20 to filter out impurities in the condensate. The filter device should be cleaned or replaced regularly to maintain its filtering effect.

[0073] In one implementation of this embodiment, the spray box 20 is provided with a plurality of overflow holes 202. When there is too much condensate in the spray box 20, the condensate overflows from the overflow holes 202.

[0074] The main function of the overflow hole 202 is to prevent excessive condensate buildup in the spray box 20. When the condensate level in the spray box 20 exceeds a certain threshold, the excess condensate will overflow from the overflow hole 202, preventing excessive water accumulation in the spray box 20 and thus protecting the spray box 20 and the condenser 2. The overflow hole 202 is located on the side or bottom of the spray box 20, higher than the drip hole 201, to ensure that under normal operating conditions, condensate can drip smoothly onto the condenser 2 without flowing out from the overflow hole 202.

[0075] The number and location of the overflow holes 202 should be evenly distributed to ensure that condensate can be discharged uniformly. The shape of the overflow holes 202 can be circular, square, or rectangular, etc. The diameter or width of the overflow holes 202 is between a few millimeters and tens of millimeters to ensure that excess water can be discharged in time when there is too much condensate.

[0076] Figure 4The diagram shown is a structural schematic of the water-cooled heat dissipation device of the integrated air conditioning unit based on a box-type spray system described in this application embodiment. (See attached diagram.) Figure 4 As shown, in one implementation of this embodiment, the chassis water collection box 30 is provided with a water guide 301, and the water guide 301 is connected to a drain solenoid valve 303.

[0077] In this embodiment, the water inlet 301 inside the chassis water collection box 30 is connected to a drain solenoid valve 303. When the integrated air conditioning unit is running, the drain solenoid valve 303 is closed to ensure that there is sufficient condensate water in the chassis water collection box 30 for spraying. When the integrated air conditioning unit stops running, the drain solenoid valve 303 will automatically open to drain the water from the chassis water collection box 30.

[0078] The water inlet 301 on the chassis water collection box 30 is connected to the inlet of the drain solenoid valve 303 via a pipe, and the outlet of the drain solenoid valve 303 is connected to the drain pipe to discharge condensate to a designated location. The interfaces connecting the pipes and the solenoid valve should be well-sealed to prevent condensate leakage. Gaskets or sealant are typically used to ensure a tight seal at the connection.

[0079] The drain solenoid valve 303 is a device that controls the opening and closing of a valve using electromagnetic force. It consists of an electromagnetic coil and a valve body. When the electromagnetic coil is energized, it generates a magnetic field, causing the valve core to move, thereby opening or closing the valve. When the air conditioning unit is running, the drain solenoid valve 303 is energized, the valve is closed, preventing condensate from draining from the chassis water collection box 30 and ensuring sufficient condensate for spraying. When the air conditioning unit stops running, the drain solenoid valve 303 is de-energized, the valve opens, and the condensate in the chassis water collection box 30 is drained through the drain inlet 301, preventing water accumulation and potential leakage problems.

[0080] The energization and de-energization of the drain solenoid valve 303 are controlled by the control board of the integrated air conditioning unit. The control board sends signals according to the operating status of the air conditioner to control the opening and closing of the solenoid valve. The coil of the solenoid valve is connected to the control board of the integrated air conditioning unit through a wire, and the control board controls the energization and de-energization of the solenoid valve according to the operating status.

[0081] Specifically, in this embodiment, the drain solenoid valve 303 uses a wax motor (thermal actuator) in conjunction with structural plastic rubber parts to form a normally open drain valve: it closes when energized and does not drain, and opens when not energized and drains. Because this drain valve is a normally open design, even if the solenoid valve fails, the drain valve can still open automatically, ensuring that the system will not malfunction due to the accumulation of condensate.

[0082] A wax motor is a device that uses the thermal expansion property of wax to drive mechanical parts. When current passes through the heating element, the wax expands due to heat, pushing a piston to move, thus achieving mechanical action. When the solenoid valve is energized, the heating element causes the wax to expand due to heat, pushing the piston to move and closing the drain valve to prevent condensate from draining. When the solenoid valve is de-energized, the heating element stops working, the wax cools and contracts, the piston returns to its original position under the action of a spring or gravity, opening the drain valve and draining the condensate through the drain pipe.

[0083] The wax motor is connected to the piston of the drain valve via a mechanical connection. When the wax motor operates, the piston moves, controlling the opening and closing of the drain valve. A seal, such as a rubber ring, is typically installed between the piston and the valve body of the drain valve to ensure that condensate is completely prevented from flowing out when closed.

[0084] Therefore, the water-cooled heat dissipation device of the air-conditioning unit based on the box-type spray described in this embodiment will automatically drain water when the air-conditioning unit is turned off, effectively preventing problems such as dampness, corrosion and bacterial growth caused by water accumulation.

[0085] In one implementation of this embodiment, the chassis water collection box 30 is provided with an overflow port 302. When the integrated air conditioning unit runs for a long time and produces too much condensate, the excess water will automatically flow out from the overflow port on the water collection box and be discharged outside the integrated air conditioning unit, preventing the condensate from overflowing the chassis water collection box 30 due to excessive condensate.

[0086] In one implementation of this embodiment, the water pump 40 is installed inside the chassis water collection box 30, drawing condensate from the chassis water collection box 30 into the spray box 20. The water pump 40 is typically located at the bottom or side of the water collection box to ensure effective condensate extraction. The water pump 40 is equipped with a water level switch and operates according to the water level detected by the water level switch. The water pump 40 has a built-in water level switch; when powered on, if the water level exceeds the water level switch, the water pump 40 automatically starts; if the water level is below the water level switch, the water pump 40 automatically shuts off.

[0087] A water level switch is a sensor used to detect the liquid level, typically consisting of a float, magnetic switch, or electrodes. The water level switch is installed on the side or top of the chassis water collection box 30, slightly above the water inlet 203 of the water pump 40, to ensure that the water pump 40 can be triggered to stop operating promptly when the water level is too low.

[0088] A water level switch is connected to the control circuit of the water pump 40 via a wire. When the water level switch is triggered, the control circuit causes the water pump 40 to start or stop. When the water level reaches the set position, the water level switch sends a signal to control the operation or stop of the water pump 40. By installing a water level switch on the water pump 40, automatic monitoring and control of the condensate water level in the chassis water collection box 30 is achieved. The water pump 40 automatically starts or shuts down according to the water level detected by the water level switch, ensuring that the condensate water in the chassis water collection box 30 can be drawn into the spray box 20 in a timely manner, while avoiding the water pump 40 from running dry due to excessively low water levels.

[0089] When the water level in the chassis water collection box 30 exceeds the set position of the water level switch, the water level switch is triggered, and the water pump 40 automatically starts, drawing condensate into the spray box 20. When the water level in the chassis water collection box 30 falls below the set position of the water level switch, the water level switch resets, and the water pump 40 automatically shuts off to prevent it from running dry. When the system is powered off, the water pump 40 stops running, regardless of the water level. This design ensures that the water pump 40 will not be damaged due to misoperation in the event of a power outage. The water pump 40 automatically starts or shuts down based on the water level detected by the water level switch, without manual intervention, improving the system's automation level. Furthermore, it ensures that the water pump 40 only operates when needed, avoiding unnecessary energy consumption and improving the system's energy efficiency.

[0090] Figure 5 The diagram shown is an electrical control schematic of the water-cooled heat dissipation device of the integrated air conditioning unit based on a box-type spray system as described in an embodiment of this application. Figure 5 As shown, in cooling mode, when the unit is turned on, the water pump 40 and the drain solenoid valve 303 are energized. The water pump 40 automatically starts and stops according to its built-in water level switch, and the drain valve is closed and does not drain water. When the unit is turned off, the water pump 40 and the drain solenoid valve 303 are not energized, the water pump 40 does not run, and the drain solenoid valve 303 opens to drain water. In heating mode, regardless of whether the unit is in on / off mode, the water pump 40 and the drain solenoid valve 303 are not energized, the water pump 40 does not run, and the drain solenoid valve 303 opens to drain water.

[0091] In summary, this embodiment of the application fully utilizes the condensate naturally generated during the cooling process of the integrated air conditioner, ensuring that the condensate is sprayed evenly and thoroughly onto the condenser 2, significantly improving the unit's energy efficiency. Simultaneously, the integrated air conditioner automatically drains water when turned off, effectively preventing problems such as moisture accumulation, corrosion, and bacterial growth.

Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
