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 tubular spraying. 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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, and 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.

[0035] 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.

[0036] This application provides a water-cooled heat dissipation device for an integrated air conditioning unit based on a tubular 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 3 This embodiment details the implementation of a water-cooled heat dissipation device for an integrated air conditioning unit based on tubular spraying.

[0037] like Figure 1 As shown in the figure, this application embodiment provides a water-cooled heat dissipation device for an integrated air conditioning unit based on pipe spraying. The water-cooled heat dissipation device for the integrated air conditioning unit based on pipe spraying in this embodiment includes: an evaporator water collection box 10, a chassis water collection box 30, and a spray pipe 60.

[0038] 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 spray pipe 6020 is installed on the top side of the condenser 2, and the condensate collected by the evaporator water collection box 10 flows into the spray pipe 60 through the water guide pipe; the spray pipe 60 is provided with a plurality of drip holes 601, and the condensate drips onto the condenser 2 through the drip holes 601 and evaporates; the chassis water collection box 30 is set at the bottom of the condenser 2 of the air conditioner unit to drain the condensate left on the condenser 2.

[0039] In this embodiment of the water-cooled heat dissipation device for an integrated air conditioning unit based on tubular spraying, the condensate generated by the evaporator 1 flows sequentially into the evaporator water collection box 10 and the spray pipe 60. The condensate in the spray pipe 60 flows out through the drip hole 601, dripping onto the condenser 2 and evaporating. This fully utilizes the condensate naturally generated by the integrated air conditioning unit during the cooling process, ensuring that the condensate is sprayed evenly and thoroughly onto the condenser 2, significantly improving the energy efficiency of the integrated air conditioning unit. Simultaneously, the chassis water collection box 30 is located at the bottom of the condenser 2 of the integrated air conditioning unit, draining the condensate remaining on the condenser 2 and effectively preventing problems such as moisture accumulation, corrosion, and bacterial growth.

[0040] The structure of the water-cooled heat dissipation device of the integrated air conditioning unit based on tubular spraying in this embodiment will be described in detail below.

[0041] 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.

[0042] 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.

[0043] The evaporator water collection box 10 is installed directly below the evaporator 1 of the air conditioning unit, in order to collect the condensate generated by the evaporator 1 during the cooling process to the greatest extent.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] In one implementation of this embodiment, a side water collection box 50 is connected between the evaporator water collection box 10 and the spray pipe 60 via a water guide pipe; the side water collection box 50 is fixed below one end of the evaporator water collection box 10. The condensate generated by the evaporator 1 flows sequentially into the evaporator water collection box 10, the side water collection box 50, and the spray pipe 60. The condensate in the spray pipe 60 flows out as water droplets through the drip hole 601, dripping onto the condenser 2 and evaporating.

[0052] In this embodiment, the spray pipe 60 is installed on the 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 2 is fixed inside the integrated air conditioning unit by a condenser fixing plate. 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.

[0053] In this embodiment, the spray pipe 60 is connected to the evaporator water collection box 10 via a water guide pipe, which is used to transport condensate. The material of the water guide pipe should have good corrosion resistance and sealing properties to prevent condensate leakage.

[0054] The spray pipe 60 is installed on the top side of the condenser 2, allowing the spray liquid to cover the surface of the condenser 2 from top to bottom. This also ensures that the condensate can drip evenly onto the surface of the condenser 2, improving cooling efficiency. The spray pipe 60 can be fixed to the top of the condenser 2 by means of brackets, screws, or clips to ensure its stable position and prevent displacement due to vibration or external force.

[0055] Specifically, such as Figure 1As shown, in one implementation of this embodiment, one end of the spray pipe 60 is fixed to the top side of the condenser 2 by a pipe clamp 602.

[0056] In this embodiment, the spray pipe 60 is attached to the top side of the condenser 2. The pipe clamp 602 surrounds the outer wall of the spray pipe 60 in the form of a "clamp". The back of the clamp (or the ear plate welded / riveted) is directly attached to the top side of the condenser 2 and locked by fasteners, so that the outer wall of the spray pipe 60 and the surface of the condenser 2 maintain line contact or tangential contact, realizing attachment rather than suspension.

[0057] In this embodiment, the inner diameter of the clamp 602 is slightly larger than the outer diameter of the spray pipe 60. After being locked, it generates friction to prevent the spray pipe 60 from moving up and down. The clamp body of the clamp 602 forms a closed force system with the surface of the condenser 2, restricting the spray pipe 60 from moving away from the surface of the condenser 2.

[0058] In this embodiment, the pipe clamp 602 is an open ring structure. The spray pipe 60 can be moved out from the top side of the condenser 2 by loosening the bolts, which is convenient for maintenance, winter venting, or replacement of spray pipes 60 with different orifice diameters.

[0059] In this embodiment, the outer wall of the spray pipe 60 is kept at a certain distance (e.g., 2cm) from the top of the fins of the condenser 2 to avoid vibration and wear.

[0060] Figure 2 The diagram shown is a structural schematic of the spray pipe 60 in the water-cooled heat dissipation device of the integrated air conditioning unit based on tubular spraying, as described in an embodiment of this application. Figure 2 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 601 in the spray pipe 60 include at least two different hole sizes. The distribution of the drip holes 601 ensures that the condensate can evenly cover the entire surface of the condenser 2, thereby improving the heat dissipation effect.

[0061] The large-diameter drip hole 601 provides a larger water flow, ensuring that condensate drips quickly onto the condenser 2, making it suitable for areas with high condensate production. In this embodiment, the large-diameter drip hole 601 is located near the inlet of the spray pipe 60. The small-diameter drip hole 601 provides a smaller water flow, ensuring that condensate is evenly distributed to all corners of the condenser 2, making it suitable for areas with low condensate production.

[0062] In this embodiment, the large-diameter drip holes 601 are positioned close to the inlet of the spray pipe 60, while the small-diameter drip holes 601 are positioned away from the inlet of the spray pipe 60. Drip holes 601 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 601 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.

[0063] In addition, if the surface area of ​​the condenser 2 is large, multiple large-diameter drip holes 601 can be set in the central area of ​​the spray pipe 60, and multiple small-diameter drip holes 601 can be set in the two side areas to ensure uniform distribution of condensate.

[0064] The drip holes 601 of different sizes are arranged in a linear pattern. The drip holes 601 of different sizes are arranged in order of size: from smallest to largest or from largest to smallest.

[0065] For example, in this embodiment, two types of drip holes 601 with different aperture sizes are provided: drip holes 601 with an aperture of 1.5 mm and drip holes 601 with an aperture of 3.0 mm. The multiple drip holes 601 with an aperture of 1.5 mm and the multiple drip holes 601 with an aperture of 3.0 mm are arranged in a line. The multiple drip holes 601 with an aperture of 3.0 mm are close to the water inlet of the spray pipe 60, while the multiple drip holes 601 with an aperture of 1.5 mm are far from the water inlet of the spray pipe 60.

[0066] In one implementation of this embodiment, the drip hole 601 of the spray pipe 60 faces downward and is at a certain angle (e.g., 30°) to the fins of the condenser 2 to ensure that the water film dripping onto the condenser 2 is uniform.

[0067] Since the drip hole 601 may be clogged by impurities in the condensate, affecting the distribution of condensate and heat dissipation, in some embodiments, a filter device, such as a filter screen or filter cotton, can be installed inside the spray pipe 60 to filter impurities in the condensate. The filter device should be cleaned or replaced regularly to maintain its filtering effect.

[0068] In one implementation of this embodiment, the spray pipe 60 may also be provided with a plurality of overflow holes. When there is too much condensate in the spray pipe 60, the condensate overflows from the overflow holes.

[0069] The main function of the overflow hole is to prevent excessive condensate buildup in the spray pipe 60. When the condensate level in the spray pipe 60 exceeds a certain threshold, the excess condensate will overflow from the overflow hole, preventing excessive water accumulation in the spray pipe 60 and thus protecting the spray pipe 60 and the condenser 2. The overflow hole is located on the side of the spray pipe 60, higher than the drip hole 601, to ensure that under normal operating conditions, condensate can drip smoothly onto the condenser 2 without flowing out of the overflow hole.

[0070] The number and location of overflow holes should be evenly distributed to ensure that condensate can be drained uniformly. The shape of the overflow holes can be circular, square, or rectangular, etc. The diameter or width of the overflow holes is between a few millimeters and tens of millimeters to ensure that excess water can be drained in time when there is too much condensate.

[0071] Figure 3 The diagram shown is a structural schematic of the water-cooled heat dissipation device of the integrated air conditioning unit based on tubular spraying, as described in an embodiment of this application. (See attached diagram.) Figure 3 As shown, in one implementation of this embodiment, the chassis water collection box 30 is provided with a water guide port 301. With this structure, the chassis water collection box 30 does not require electrically controlled drainage; the condensate flowing down from the condenser 2 will be directly discharged from the unit through the water guide port 301. This also eliminates the need for an electronic control board for the water-cooled heat dissipation device of the integrated air conditioning unit based on tubular spraying, resulting in a simple structure, fewer required components, and lower cost.

[0072] In other embodiments, the water inlet 301 can also be connected to a drain solenoid valve. When the integrated air conditioning unit is running, the drain solenoid valve 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 will automatically open to drain the water from the chassis water collection box 30.

[0073] The water inlet 301 on the chassis water collection box 30 is connected to the inlet of the drain solenoid valve via a pipe, and the outlet of the drain solenoid valve is connected to the drain pipe to discharge condensate to a designated location. The interface connecting the pipe 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.

[0074] A drain solenoid valve 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 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 is de-energized, the valve opens, and condensate in the chassis water collection box 30 is drained through the drain inlet 301, preventing water accumulation and potential leakage problems.

[0075] The energization and de-energization of the drain solenoid valve are controlled by the control board of the integrated air conditioning unit. The control board sends signals based on 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 via wires, and the control board controls the energization and de-energization of the solenoid valve according to the operating status.

[0076] Specifically, in this embodiment, the drain solenoid valve uses a wax motor (thermal actuator) in conjunction with structural plastic and rubber components 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 malfunctions, the drain valve can still open automatically, ensuring that the system will not malfunction due to the accumulation of condensate.

[0077] 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.

[0078] 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.

[0079] Therefore, the water-cooled heat dissipation device of the integrated air conditioner based on pipe spraying described in this embodiment will automatically drain water when the integrated air conditioner is turned off, effectively preventing problems such as dampness, corrosion, and bacterial growth caused by water accumulation.

[0080] 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 302 on the chassis water collection box 30 and be discharged outside the integrated air conditioning unit, preventing the condensate from overflowing the chassis water collection box 30 due to excessive condensate.

[0081] In summary, the embodiments of this application fully utilize the condensate naturally generated during the cooling process of the integrated air conditioning unit, ensuring that the condensate is sprayed thoroughly and evenly onto the condenser, significantly improving the unit's energy efficiency. Simultaneously, the integrated air conditioning unit effectively prevents problems such as dampness, corrosion, and bacterial growth caused by water accumulation.

[0082] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. 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.
