Description

Technical Field

[0001] This invention relates to the field of indoor air conditioning units, and particularly to a cross-flow air conditioning convection device. Background Technology

[0002] Commonly available air conditioning indoor units include wall-mounted air conditioners, multi-split systems, fan coil units, box-type air conditioners, and ducted air conditioners. These types of indoor units all use a chiller / heater unit to provide the medium for cooling and heating. Generally, these indoor units are relatively large, requiring installation in the ceiling or on the wall, resulting in significant space loss, noise, strong drafts, and limited functionality. In traditional products, components such as the air outlet, return air outlet, surface cooler, fan, and drip tray are all concentrated around the front and rear of the surface cooler. Within such a short unit, the surface cooler needs cooling capacity, the fan needs airflow and pressure, and the air outlet must also meet the cooling capacity and airflow requirements of the surface cooler without being confined within the unit. This mechanical principle makes it difficult to reduce the size and noise of the unit. It's also noticeable that central air conditioning indoor units, regardless of the brand, are almost identical in terms of mechanical structure, shape, length, thickness, and depth. The machine body is too thick and takes up floor height. In order to reduce the floor height occupied during the installation process, holes are drilled in the load-bearing beams to install pipes, which causes serious damage to the building structure.

[0003] On the other hand, traditional air conditioner indoor units have limited functions. When consumers require higher air quality, they need to add more independent equipment to assist in achieving the corresponding functions, such as adding fresh air equipment, humidification equipment, and dehumidification equipment.

[0004] CN206073511U discloses a heat exchange structure, an air conditioner, and its indoor and outdoor units. Firstly, it employs a four-sided air intake and exhaust system to achieve heat exchange. The microchannel heat exchanger in this system is constructed using a finned tube design, manufactured using a non-extrusion, one-piece molding process. Secondly, a fan directly supplies air to the microchannel heat exchanger. Since the microchannel heat exchanger relies on direct airflow from the fan to achieve heat exchange, areas where the fan doesn't reach will lose their heat exchange effect. Therefore, the cooling capacity of a microchannel heat exchanger cannot be calculated based on its length. Finally, the same side of the microchannel heat exchanger has both air intake and exhaust. During operation, the fan generates a high intake air velocity, but the airflow velocity is reduced when the fan's exhaust air pressure is blocked by the microchannel heat exchanger. This can cause short circuits between the return and exhaust air, resulting in a poorer heat exchange effect.

[0005] CN104534574A discloses an outdoor unit and air conditioner, in which the fan is surrounded by a barrel-shaped microchannel heat exchanger. This is a microchannel heat exchanger with a tube-through method, and it is not a microchannel heat exchanger formed by extrusion in one piece. The fan and the microchannel heat exchanger are integrated together, which makes it impossible to achieve miniaturization of the unit body.

[0006] The above are the areas that need to be improved in this application. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a cross-flow air conditioner convection unit with a thin body, which can be spliced ​​to any length or width, with balanced heat dissipation, full functionality, various installation methods, and surface decoration that can be completely integrated into the decoration style.

[0008] To address the aforementioned technical issues, this invention provides a cross-flow air conditioning convection unit, comprising a fan, an insulated outer shell, a return air nozzle, and an air outlet nozzle. It also includes a long, narrow microchannel surface cooler with a flat, porous flow channel. The microchannel surface cooler is installed in the middle of the insulated outer shell, with accommodating spaces between its two ends and the shell. A return air nozzle is installed in one end of the accommodating space, while an air outlet nozzle and a fan are installed in the other end. The microchannel surface cooler is constructed using a high thermal conductivity metal material, extruded to form an integrated structure of the medium flow channel and fins. The fan's exhaust principle creates negative pressure inside the air conditioning convection unit, allowing air to enter the long, narrow microchannel surface cooler through the return air nozzle for heat exchange. The residence time and flow path length of the air flowing through the microchannel surface cooler determine the heat exchange effect, unlike traditional air conditioners that rely on a fan to force air through the surface cooler for heat exchange.

[0009] The microchannel surface cooler is made of high thermal conductivity metal material through a one-time extrusion process. It has stronger heat exchange capacity, is thinner and lighter than other materials of the same volume, and has a smaller size and higher pressure resistance. It is suitable for high-pressure refrigerant radiators, which are more compact. The medium flow channel and fins are integrated into one structure. Multiple parallel fins are arranged on both sides of the medium channel, and air ducts are formed between the two fins. The length of the fins is equal to the length of the microchannel surface cooler. The surface of the fins is wavy to reduce the resistance of medium transport and improve the heat conduction effect.

[0010] The cross-flow air conditioner convection unit has a thickness of 7cm to 15cm, a width of 20cm to 80cm, and a length of 120cm to 240cm. Specifically, the microchannel surface cooler is a long, strip-shaped microchannel surface cooler with a flat tube and multiple perforated channels. The microchannel surface cooler utilizes a long strip-shaped heat dissipation area, using this shape as the basis for calculating the heat dissipation area, i.e., determining the square base of the fins and the time it takes for air to pass through the fins. The flat tube-type, thin microchannel surface cooler reduces the space occupied within the unit body.

[0011] The microchannel surface cooler is a single microchannel surface cooler unit, or multiple microchannel surface cooler units connected in series to achieve the required length, or multiple microchannel surface cooler units arranged side by side to achieve the required width. The fins are arranged in the same direction as the medium flow channel, and the surface of the fins is wavy.

[0012] The microchannel surface cooler uses a high thermal conductivity capillary as the medium flow channel, and fins are added to the capillary. The arrangement of the capillary medium flow channel and the fins presents a cross-shaped structure.

[0013] The surface of the insulation shell of the cross-flow air conditioner convection unit is detachably fitted with a decorative material, which may be a glass backlight panel, wood veneer, leather veneer, metal veneer, plastic veneer, fiber veneer, or a colored coating. The decorative material on the surface of the air conditioner convection unit is completely integrated into the decoration style, achieving the effect of soft furnishing the appliance.

[0014] The cross-flow air conditioning convection unit also includes a heat source device, a circulating pump, a water tank, valves, a condensate drain pipe, a lift pump, a transformer, a control panel, a linkage module, inlet and outlet water pipes, and various functional devices. The water tank is connected to the heat source device via the inlet and outlet water pipes. The water tank is connected to the valves via the circulating pump, and then to the microchannel surface cooler. The bottom of the insulation shell is connected to the condensate drain pipe, which is connected to the lift pump. The lift pump is connected to the distribution box via the transformer. The control panel is connected to the linkage module, which is connected to the circulating pump, valves, fan, and various functional devices, or directly supplies refrigerant to the microchannel surface cooler via the heat source device. The condensate from the cross-flow air conditioning convection unit is drained away by the lift pump or by a high-low water level difference.

[0015] The space at both ends of the insulated outer shell allows for the installation of any one or more functional devices as needed. These devices include, but are not limited to: transformers, aromatherapy diffusers, humidifiers, ultraviolet lamps, negative ion generators, heating devices, self-priming chargers, and audio equipment. This enhances the added value of the air conditioner's indoor unit, addressing the shortcomings of traditional single-function air conditioners, facilitating the development trend of smart homes, and meeting the needs of modern life. For ceiling-mounted cross-flow air conditioner convection units, lighting is embedded on both sides; for wall-mounted cross-flow air conditioner convection units, audio equipment is mounted on the side, and a self-priming charger and control panel are mounted on the front; for floor-mounted cross-flow air conditioner convection units, the insulated outer shell connects to the outdoor fresh air duct and fresh air fan, with the fan, air outlet, and return air nozzle transferred to the wall via elbows in the insulated outer shell.

[0016] The control panel and linkage module control the functions of the cross-flow air conditioner convection unit via the 485 communication protocol, including voice control, remote control, and remote control.

[0017] The microchannel surface cooler is a heat exchange component that receives water or other refrigerants as the medium.

[0018] The microchannel surface cooler is provided with an even number of medium flow channels, and the medium in the medium flow channels flows in opposite directions to achieve a balanced heat dissipation effect.

[0019] When the fan at one end of the insulation shell is running and exhausting air, indoor air enters the insulation shell through the return air vent at the other end. Alternatively, a fan can be added at the return air vent to increase the return air volume. The air flows in the air duct formed by multiple fins, and when it reaches the exhaust fan position after passing through the microchannel surface cooler, the air is cooled or heated by the cooling or heating effect of the microchannel surface cooler. The section of the insulation shell where the microchannel surface cooler is installed is called the "cooling" section, and the section of the insulation shell where various functional devices are installed is called the "functional" section.

[0020] A heat source device is a device that provides a hot or cold medium, such as water, refrigerant, or liquid cooling. The heat source device, in conjunction with solar energy and battery storage, forms a multi-energy complementary system. The circulating pump, water tank, inlet and outlet water pipes, and valves are specifically designed to provide the medium for the microchannel surface cooler. The circulating pump is used to circulate the hot or cold medium. The water tank is used to store and retrieve the hot or cold medium. The valves are used to control the medium delivery requirements. The inlet and outlet water pipes are used to transport the medium. The heat source device is connected to the water tank via the inlet and outlet water pipes. The water tank is connected to the valves via the circulating pump, and then to the microchannel surface cooler. A condensate drain pipe is connected to the bottom of the insulation shell, and the condensate drain pipe is connected to a booster pump. The booster pump is connected to the distribution box via a transformer.

[0021] The cross-flow air conditioner convection unit is thin and long, and there are several installation methods: one is to install it directly underground; the other is to transfer the fan, air outlet and return air outlet to the side wall through the elbow of the insulated shell, and install the microchannel surface cooler underground; the third is to install it in the wall through wall grooves, soft partitions or wall panels, or to hang it on the wall surface.

[0022] The fan is used to circulate and exchange heat between indoor air and the microchannel surface cooler. Each cross-flow air conditioner convection unit is equipped with at least one fan. The fan is part of the exhaust or supply air unit and is installed in the housing space of the insulation shell or partially protrudes from the surface of the insulation shell. The number of fans is determined according to the cooling capacity of the cross-flow air conditioner convection unit.

[0023] The microchannel surface cooler is used to generate cold or heat.

[0024] The insulation shell is used to install the microchannel surface cooler and other auxiliary functional devices. The insulation shell connects to the fresh air duct and fresh air fan leading to the outside. The insulation shell is connected in sections or with upper and lower snap-fit ​​connections.

[0025] The humidifier is used to humidify the air.

[0026] The ultraviolet light is used to sterilize the air.

[0027] The negative ion generator is used to increase the oxygen content of indoor air.

[0028] The aroma diffuser is used to add a touch of style to a living space.

[0029] The sound system is for leisure and entertainment.

[0030] The surface decorative material is used to enhance the decorative effect, achieve an electrical soft furnishing effect, and is removable and replaceable.

[0031] The air outlet is used to protect personal safety and the safety of the fan.

[0032] The return air nozzle is used to prevent dust or objects from entering the insulation shell.

[0033] The condensate drain pipe is used to drain the condensate produced by the microchannel surface cooler.

[0034] The booster pump is used to drain condensate from indoors to outdoors.

[0035] The control panel sends control commands to the linkage module via 485 communication.

[0036] The linkage module receives instructions from the control panel and precisely controls all functional devices, including heat source equipment and circulation pumps, and features remote control and voice control.

[0037] The heating device is used to heat the air.

[0038] The fresh air fan is used to introduce outdoor air.

[0039] The self-priming charger is used to charge mobile phones.

[0040] The one or more technical solutions proposed in this invention have at least the following beneficial effects: 1) Due to its ultra-thin body, the cross-flow air conditioner convection unit can be installed in a variety of space-saving ways, such as being hidden underground, hidden in the wall, or openly mounted on the wall or suspended from the ceiling. 2) The surface of the cross-flow air conditioner convection unit is designed with a variety of decorative surfaces, which effectively solves the problem that the appearance cannot meet the combination of architecture and aesthetics and is difficult to integrate into the decoration style of modern families. 3) The surface of the cross-flow air conditioner convection unit is decorated with wood, metal, leather, luminous glass, mirror, fiber, colored coating and other finishes, effectively meeting the needs of different consumer groups and different decoration styles; 4) The cross-flow air conditioner comes with various functional devices, including a negative ion generator, automatic humidification, fresh air, air purification, self-priming charger, audio, ultraviolet air sterilization, aromatherapy, heater, automatic noise adjustment, dynamic control of airflow organization, etc., which solves the problem of the single function of traditional air conditioners and provides consumers with a better living space. 5) The microchannel surface coolers designed for cross-flow air conditioners are thin and elongated, which increases the time that air stays inside, resulting in better outlet air temperature and dehumidification, effectively increasing the energy efficiency ratio and achieving significant energy saving, thus meeting the goals of energy conservation and emission reduction. 6) Cross-flow air conditioning convection units are used in spacious living spaces. Cross-flow air conditioning convection units installed underground or in the ceiling require multiple cross-flow air conditioning convection units to extend their length. Each cross-flow air conditioning convection unit is equipped with a fan to ensure cooling capacity and airflow. The length of each cross-flow air conditioning convection unit is fixed. The fan, air outlet, return air outlet, functional devices, and fresh air are already installed inside the cross-flow air conditioning convection unit. On-site installation only requires end-to-end snap-fit ​​connection, including wiring plug terminal connection. It has strong standardization, quality assurance, and effectively reduces installation costs. Attached Figure Description

Detailed Implementation

[0042] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] like Figure 1As shown, the present invention provides a cross-flow air conditioner convection unit, including an insulated outer shell 7 of the air conditioner convection unit body and a microchannel surface cooler 6 installed in the middle of the insulated outer shell 7, a heat source device 1, a circulation pump 2, a water tank 3, a valve 4, a condensate drain pipe 15, a booster pump 16, a transformer 20, a control panel 17, a linkage module 18, inlet and outlet water pipes 19, a lighting lamp 21, an aromatherapy diffuser 22, a humidifying spray device 8, an ultraviolet lamp 9, a self-priming charger 23, a negative ion generator 10, a sound system 24, a fresh air fan 13, and a heating device 14. When the fan 5 at one end of the insulation shell 7 is running and exhausting air, indoor air enters the insulation shell 7 through the return air nozzle 12 at the other end of the insulation shell 7, or a fan 5 is added at the return air nozzle 12 to increase the return air volume. Decorative material 25 is detachably installed on the surface of the insulation shell 7. Air flows in the air duct formed by multiple fins 602, and when it reaches the exhaust fan position after passing through the microchannel surface cooler unit 6, the air is cooled or heated by the cooling or heating effect of the microchannel surface cooler 6. Figure 13 As shown, the insulation shell 7 at the location where the microchannel surface cooler is installed is called the "cooling" section, and the insulation shell for installing various functional devices is called the "functional" section.

[0044] like Figure 4 As shown, the microchannel surface cooler 6 is formed in one piece using a high thermal conductivity aluminum alloy through an extrusion process, making the dual-medium flow channel 601 and fins 602 an integral structure. The length of the fins 602 is equal to the length of the microchannel surface cooler 6. Multiple parallel fins 602 are arranged on both sides of the dual-medium flow channel 601, forming air ducts between pairs of fins 602, replacing the traditional process of copper tubes threaded through fins and reducing the amount of copper used. The surface of the fins 602 is wavy, reducing the resistance to medium transport and improving the heat conduction effect. The dual-medium flow channel 601 is provided with an interface for connecting to the inlet and return water pipes 19.

[0045] The microchannel surface cooler 6 is ultra-thin and elongated, and the microchannel surface cooler 6 adopts an elongated heat dissipation area. The elongated shape is used as the basis for calculating the heat dissipation area. In this embodiment, the cooling capacity of the microchannel surface cooler 6 is set to 2500W / 1.5m. The ultra-thin microchannel surface cooler 6 reduces the space occupied inside the machine body.

[0046] like Figure 3 As shown, the microchannel surface cooler 6 has a receiving space between its two ends and the insulation shell 7. One end of the receiving space is equipped with a return air nozzle 12, and the other end of the receiving space is equipped with an air outlet nozzle 11 and a fan 5. The exhaust principle of the fan 5 creates a negative pressure state inside the unit, allowing indoor air to enter the microchannel surface cooler 6 inside the unit through the return air nozzle 12 for heat exchange. This avoids the need for traditional air conditioner indoor units to consider the installation position of the fan and air inlet / outlet nozzles in the heat dissipation section of the surface cooler.

[0047] like Figure 3 As shown, the accommodating space can be equipped with one or more of the following functional devices according to functional needs: lighting 21, aromatherapy diffuser 22, humidifying spray device 8, ultraviolet lamp 9, self-priming charger 23, negative ion generator 10, audio equipment 24, and heating device 14. This expands the additional value-added functions of the cross-flow air conditioner convection unit, solves the shortcomings of the single function of traditional air conditioner indoor units, is conducive to the development trend of smart housing, and meets the needs of modern life.

[0048] The water tank 3 is connected to the inlet and outlet water pipes 19 of the heat source device 1. The water tank 3 is connected to the valve 4 via the circulation pump 2, and then to the microchannel surface cooler 6. The bottom of the insulation shell 7 is connected to the condensate drain pipe 15, which is connected to the lift pump 16. The lift pump 16 is connected to the distribution box via the transformer 20. The control panel 17 is connected to the linkage module 18, which is connected to the circulation pump 2, valve 4, fan 5, lighting 21, aromatherapy diffuser 22, humidifying spray device 8, ultraviolet lamp 9, self-priming charger 23, negative ion generator 10, audio system 24, fresh air fan 13, and heating device 14. Figure 14 As shown, when using any functional device of the cross-flow air conditioner convection unit, first locate the corresponding display confirmation button on the function page of the control panel 17. For example, if humidification is required, find the word "humidify" on the function page and press the confirmation button. The humidity detector of the control panel 17 will determine the humidity of the indoor air. When the control panel 17 detects that the indoor air moisture content is lower than the set value, the control panel 17 will turn on the power to the miniature relay in the linkage module 18 via the 485 communication protocol. The humidifying spray device 8 will then spray water mist to humidify the air. The humidifying spray device 8 will stop working when the control panel 17 detects that the indoor air moisture content has reached the set value.

[0049] The working principle of this invention is as follows: The hot or cold medium generated by the outdoor heat source device 1 is transported through the inlet and outlet water pipes 19, water tank 3, and circulating pump 2 to the medium flow channel 601 of the microchannel surface cooler 6 inside the insulation shell 7. This allows the microchannel surface cooler 6 to generate cooling or heating. When indoor air enters the insulation shell 7 through the return air vent 12, the air temperature changes as it flows through the elongated microchannel surface cooler 6. When the fan 5 at the other end runs, the air inside the entire microchannel surface cooler 6 is sent into the room by the fan 5. Figure 2 As shown, outdoor air is introduced into the insulation shell 7 of the cross-flow air conditioner convection unit through the fresh air duct and fresh air fan 13, and the fresh air achieves good dehumidification and heat exchange effects.

[0050] Various decorative materials 25 can be detachably installed on the surface of the insulation shell 7 of the cross-flow air conditioner convection unit. These materials include wood veneer, metal veneer, glass veneer, plastic veneer, leather veneer, fiber veneer, or colored coatings to match various decorating styles. Adhesive tape is pasted onto the base plate of the decorative material 25 to fix it to the surface of the insulation shell 7, and screws are used to secure it to the sides for easy replacement.

[0051] The thickness of the cross-flow air conditioner convection unit is within 7-15cm, with an optimal thickness of 8cm, and the width is within 20-80cm. The total length, including the accommodating space at both ends, is no more than 240cm, and the length of the microchannel surface cooler 6 is at least 150cm.

[0052] The cross-flow air conditioner convection unit uses multiple microchannel surface coolers 6 connected in series by length, such as... Figure 5a and Figure 5b As shown, two microchannel surface coolers 6 are connected via connector 603 to achieve the required length. In this embodiment, the microchannel surface cooler 6 is provided with dual-medium flow channels 601, and the interface 603 connects the dual-medium channels 601 of the microchannel surface cooler 6, as shown. Figure 5a As indicated by the arrow, the dual-medium channel 601 of the microchannel surface cooler unit 6 contains inlet and outlet water, and the water medium flows in opposite directions in their respective medium channels to achieve a balanced heat dissipation effect.

[0053] like Figure 5c As shown, two microchannel surface cooler units 6 are connected in the width direction. The dual medium channels 601 of the microchannel surface cooler 6 are connected through interface 603. The inlet medium channel and the outlet medium channel are connected respectively. The same end of the microchannel surface cooler 6 contains an inlet and an outlet. The water medium flows in opposite directions in their respective medium channels to achieve a balanced heat dissipation effect.

[0054] The condensate from the cross-flow air conditioner convection unit is discharged by a booster pump 16, or by a high-low drop method.

[0055] The cross-flow air conditioner convection unit has a thin and long body and is installed underground. The fan 5, air outlet 11 and return air outlet 12 are transferred to the wall through the bend of the insulation shell 7, or the cross-flow air conditioner convection unit is installed inside the wall through a groove, soft partition or wall panel.

[0056] The cross-flow air conditioner convection unit is a slim, elongated design, and can be installed in various ways to suit different decorating styles. 1) such as Figure 11 As shown, it is installed directly underground, with only the air outlet 11 and return air outlet 12 remaining on the ground. 2) such as Figure 12As shown, the fan 5, air outlet 11 and return air outlet 12 are transferred and installed inside the side wall or openly mounted on the wall through the elbow of the insulation shell 7, and the cross-flow air conditioner convection unit is installed underground. 3) such as Figure 6 The installation shown is hidden inside the side wall, with only the air outlet 11 and return air outlet 12 visible on the wall surface; 4) such as Figures 7-9 The exposed wall-mounted type shown has the return air nozzle 12 at the bottom, the air outlet nozzle 11 and the fan 5 at the top, and a condensate drain pipe 15 and an inlet and return water pipe 19 at the bottom. The inlet and return water pipe 19 is equipped with a valve 4. Various surface decorative materials 25 can be detachably installed on the heat insulation shell 7 of the cross-flow air conditioner convection unit as needed. The surface decorative materials are glass backlight panels, wood veneer, leather veneer, metal veneer, plastic veneer, fiber veneer, or colored coating. In addition, according to the needs of the product itself, patterns, or lights 21, or speakers 24, or function control panels, or self-priming chargers 23 can be set on the body. 5) such as Figure 12 As shown, the cross-flow air conditioner is suspended at both ends by hangers. In addition to the fan 5, air outlet 11 and return air outlet 12, the insulation shell 7 is embedded with lighting 21. It is suspended in large office spaces, supermarkets or restaurants, with rows of lighting 21 carrying cool air, which is both beautiful and practical.

The cross-flow air conditioning convection unit installed underground or in the ceiling extends its length by connecting multiple cross-flow air conditioning convection units. Each cross-flow air conditioning convection unit is equipped with a fan to ensure cooling capacity and airflow.

[0058] The cross-flow air conditioning convection units installed underground or in the ceiling have a fixed length. Each cross-flow air conditioning convection unit is equipped with a fan, air outlet, return air outlet, one or more functional devices, and fresh air in the space at both ends. On-site, only end-to-end snap-fit ​​connection of the unit body is required, including wiring plug terminal connection. It is highly standardized, quality is guaranteed, and installation costs are effectively reduced.
