Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a portable air conditioner. Background Technology

[0002] Current air conditioning products generally use compressors to drive refrigerant circulation, achieving heat exchange between indoors and outdoors by changing the physical state of the refrigerant (liquid to gas). While this compressor-based technology is mature and widely used, the high manufacturing cost of its core component, the compressor, directly leads to a high price for the entire unit, increasing the burden on consumers. Therefore, seeking a technological path to reduce the manufacturing cost of air conditioners is of practical significance.

[0003] In contrast, some portable air conditioning solutions attempt to bypass the compressor, using water flow directly or indirectly for heat exchange, thus avoiding the high costs associated with compressors. However, these water-cooling solutions often suffer from low efficiency during heat exchange, and their heat exchange rate and final cooling effect usually fail to meet user needs, limiting their application potential in high-efficiency cooling scenarios. Utility Model Content

[0004] In view of this, the present invention provides a portable air conditioner to solve the problems of low heat exchange efficiency, heat exchange rate and final cooling effect of the existing portable air conditioners that are difficult to meet user needs.

[0005] To achieve one or more of the above objectives or other objectives, this utility model proposes a portable air conditioner, including an indoor unit, an outdoor unit, and a water pump. The indoor unit includes a liquid-cooled heat exchanger, a compressor, an evaporator, and a first fan. The liquid-cooled heat exchanger includes a refrigerant channel and a heat exchange channel that are isolated from each other. The outlet of the refrigerant channel is connected to the evaporator inlet via an expansion valve. The evaporator outlet is connected to the compressor inlet, and the compressor outlet is connected to the refrigerant channel inlet. The first fan drives indoor air to flow through the evaporator for heat exchange. The outdoor unit includes a water tank, a water curtain, and a second fan. The outlet of the heat exchange channel is connected to the top of the water tank, and the bottom of the water tank is connected to the heat exchange channel inlet via a water pump. An air inlet and an air outlet are provided on the side wall of the water tank. The water curtain covers the inner wall of the air inlet. The second fan is located at the air outlet and can drive external air to pass through the water curtain. The heat exchange medium flowing into the water tank flows downward through the water curtain and is cooled by ventilation by the second fan.

[0006] Preferably, the indoor unit further includes a housing, in which the compressor, liquid-cooled heat exchanger, evaporator and first fan are all installed. The outdoor unit further includes a water box, which is located at the top of the water tank. A water outlet is provided on the bottom wall of the water box, which is opposite to the upper end of the water curtain. The heat exchange channel outlet is connected to the top of the water box.

[0007] Preferably, the water pump is installed in the casing or water tank.

[0008] Preferably, there are multiple water outlet holes, and the multiple water outlet holes are distributed in a matrix.

[0009] Preferably, the air inlet is a slotted air inlet.

[0010] Preferably, the water tank has multiple air inlets, and the water curtain has multiple inlets, each corresponding to one of the air inlets.

[0011] Preferably, an atomizer is provided at the top of the inner cavity of the water box, and the outlet of the heat exchange channel is connected to the atomizer.

[0012] Preferably, the water pump is arranged adjacent to the outdoor unit, the outlet of the heat exchange channel is connected to the top of the water tank through a hose, and the water pump is connected to the inlet of the heat exchange channel through a hose.

[0013] Preferably, the heat exchange channel inlet, heat exchange channel outlet, top of the water tank, and water pump are all connected to corresponding hoses via quick connectors.

[0014] Preferably, the heat exchange medium is water.

[0015] Implementing the embodiments of this utility model will have the following beneficial effects: After adopting the aforementioned portable air conditioner, during operation, the refrigerant is compressed by the compressor and flows to the evaporator through the refrigerant channel. During this process, the heat of the refrigerant is transferred to the heat exchange medium within the heat exchange channel via a liquid-cooled heat exchanger. Then, the liquid refrigerant vaporizes through an expansion valve (not shown in the attached diagram) and enters the evaporator. The continuously vaporizing refrigerant absorbs heat from the evaporator, causing its temperature to drop. Finally, under the blowing of the first fan, the evaporator absorbs heat from the indoor air, thus achieving indoor cooling. Simultaneously, driven by the water pump, the heat exchange medium carries away the heat of the refrigerant through the heat exchange channel and flows in from the top of the water tank, passing through the water curtain. The water flows downwards and is cooled by ventilation from the second fan. The cooled heat exchange medium accumulates at the bottom of the tank and is then pumped back into the heat exchange channel. This cycle repeats continuously, achieving heat exchange between the indoor and outdoor units. This prevents the heat generated by cooling from affecting the room temperature. The water curtain and the second fan dissipate heat from the heat exchange medium, further improving the cooling efficiency of the heat exchange medium while avoiding the use of the compressor in the outdoor unit. This effectively improves the heat exchange efficiency between the heat exchange medium and the refrigerant, thereby enhancing the cooling effect of the indoor unit. This ensures that the heat exchange rate and the final cooling effect of the portable air conditioner meet user needs and unleash its application potential in high-efficiency cooling scenarios.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, a portable air conditioner includes an indoor unit, an outdoor unit, and a water pump 3. The indoor unit includes a liquid-cooled heat exchanger 11, a compressor 12, an evaporator 13, and a first fan 14. The liquid-cooled heat exchanger 11 includes a refrigerant passage and a heat exchange passage that are isolated from each other. The outlet of the refrigerant passage is connected to the inlet of the evaporator 13 via an expansion valve. The outlet of the evaporator 13 is connected to the inlet of the compressor 12. The outlet of the compressor 12 is connected to the inlet of the refrigerant passage. The first fan 14 drives indoor air to flow through the evaporator 13 for heat exchange. The outdoor unit includes a water tank 2, a water curtain 24, and a second fan 25. The heat exchange passage outlet... The top of the water tank 2 is connected to the water tank 2, and the bottom of the water tank 2 is connected to the heat exchange channel inlet via the water pump 3. An air inlet 21 and an air outlet 22 are opened on the side wall of the water tank 2. A water curtain 24 covers the inner wall of the air inlet 21. A second fan 25 is located at the air outlet 22 and can drive external air through the water curtain 24. The heat exchange medium flowing into the water tank 2 flows downwards through the water curtain 24 and is cooled by the second fan 25. During operation, the refrigerant is compressed by the compressor 12 and flows through the refrigerant channel to the evaporator 13. In this process, the heat of the refrigerant is transferred to the heat exchange channel through the liquid-cooled heat exchanger 11. The heat exchange medium inside the tank 2 is then vaporized through an expansion valve (not shown in the attached diagram) and enters the evaporator 13. The continuously vaporizing refrigerant absorbs heat from the evaporator 13, causing its temperature to drop. Finally, under the blowing of the first fan 14, the evaporator 13 absorbs heat from the indoor air, thus achieving indoor cooling. At the same time, driven by the water pump 3, the heat exchange medium carries away the heat of the refrigerant through the heat exchange channel and flows in from the top of the water tank 2, flows downward through the water curtain 24, and is cooled by ventilation from the second fan 25. The cooled heat exchange medium is then accumulated. At the bottom of the water tank 2, the water flows back into the heat exchange channel via the water pump 3, and this cycle repeats to achieve heat exchange between the indoor and outdoor units. This avoids the heat generated by the cooling system affecting the room temperature. The water curtain 24 and the second fan 25 dissipate heat for the heat exchange medium. This not only avoids the use of the compressor 12 in the outdoor unit, but also further improves the cooling efficiency of the heat exchange medium. This effectively improves the heat exchange efficiency between the heat exchange medium and the refrigerant, thereby improving the cooling effect of the indoor unit. This ensures that the heat exchange rate and the final cooling effect of the portable air conditioner meet user needs and unleash its application potential in high-efficiency cooling scenarios.

[0023] Specifically, the water curtain 24 has a hollow structure. Both the liquid-cooled heat exchanger 11 and the water curtain 24 can be purchased through market channels, which will not be described in this embodiment.

[0024] Furthermore, the indoor unit also includes a housing 1, in which the compressor 12, liquid-cooled heat exchanger 11, evaporator 13 and first fan 14 are all installed. The outdoor unit also includes a water box 23, which is located on top of the water tank 2. A water outlet 231 is provided on the bottom wall of the water box 23, which is opposite to the upper end of the water curtain 24. The heat exchange channel outlet is connected to the top of the water box 23. After the heat exchange medium flows into the water box 23 from the liquid-cooled heat exchanger 11, it will drip onto the top of the water curtain 24 through the water outlet 231 and slowly flow down the water curtain 24 to the bottom of the water tank 2. At the same time, the second fan 25 will drive the outside air into the water tank 2 through the air inlet 21 and exhaust it through the air outlet 22, thereby using the outside air to cross the water curtain 24 to help the heat exchange medium dissipate heat.

[0025] In one embodiment, the bottom of the housing 1 is provided with casters 15 and the top of the housing 1 is provided with a handle 16 so that the user can move the indoor unit and adjust the direction of the cold air according to the indoor layout.

[0026] Furthermore, the water pump 3 is disposed in the housing 1 or the water tank 2. In this embodiment, the water pump 3 is preferably disposed in the water tank 2. The water pump 3 can be a submersible pump disposed at the bottom of the inner cavity of the water tank 2 or disposed below the water tank 2.

[0027] Furthermore, multiple water outlets 231 are provided, and the multiple water outlets 231 are distributed in a matrix so that the heat exchange medium drips evenly onto the top of the water curtain 24, ensuring that the heat exchange medium flows evenly on the water curtain 24 and increasing the heat dissipation area of ​​the heat exchange medium.

[0028] Furthermore, the air inlet 21 is a slotted air inlet to isolate external debris and prevent debris from entering the water tank 2 through the air inlet 21.

[0029] Furthermore, the water tank 2 is provided with multiple air inlets 21, and multiple water curtains 24 are provided, which are arranged one-to-one with the air inlets 21, so as to increase the heat dissipation area of ​​the heat exchange medium in the water tank 2 and improve the heat dissipation efficiency by increasing the number of water curtains 24.

[0030] Furthermore, an atomizer 26 is provided at the top of the inner cavity of the water box 23, and the heat exchange channel outlet is connected to the atomizer 26. The heat exchange medium is atomized by the atomizer 26 and falls to the bottom of the water box 23, which can further increase the contact area between the heat exchange medium and the air and improve the heat dissipation effect.

[0031] Furthermore, the water pump 3 is installed adjacent to the outdoor unit, and the outlet of the heat exchange channel is connected to the top of the water tank 2 via a hose. The water pump 3 is connected to the inlet of the heat exchange channel via a hose, so that the indoor unit and the outdoor unit are flexibly connected via a hose (not shown in the attached figure), which facilitates the movement of the indoor unit.

[0032] Furthermore, the heat exchange channel inlet, heat exchange channel outlet, top of water tank 2, and water pump 3 are all connected to corresponding hoses via quick connectors (not shown in the attached diagram). This reduces the difficulty of disassembling and connecting the outdoor and indoor parts of the portable air conditioner, simplifies the installation and disassembly of the portable air conditioner, lowers the technical requirements for its assembly and disassembly, and effectively reduces the assembly costs for ordinary consumers when transferring the portable air conditioner. The quick connectors can be purchased through market channels and are not described in this embodiment. Furthermore, the heat exchange medium is water.

[0033] Furthermore, the heat exchange medium can be any fluid with heat adsorption capacity. In this embodiment, water is preferred. Using water as a heat exchange medium is not only economical and environmentally friendly, but also easy for users to replenish themselves, reducing the threshold for later maintenance.

[0034] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
