Description

Technical Field

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

[0002] The heat exchange structure is the core system for portable air conditioners to achieve their cooling function. Its design rationality directly determines the cooling efficiency, energy consumption level and user experience. Traditional portable air conditioners are limited by the design concept of "single heat exchange and passive drainage". The heat exchange mechanism has obvious shortcomings, resulting in insufficient cooling efficiency and prominent potential safety hazards. Traditional portable air conditioners rely solely on basic heat exchange between the condenser and evaporator for cooling, lacking auxiliary cooling methods: they absorb heat only through refrigerant phase change, resulting in a single heat exchange path and limited area, leading to a slow cooling rate that cannot meet the demand for rapid cooling; in high-temperature environments, the condenser's heat dissipation is limited and there are no active cooling measures, resulting in a significant decrease in cooling efficiency, and after long-term use, the heat exchange components are prone to further efficiency decline due to aging; at the same time, the refrigerant diversion design is imperfect, which can easily lead to local "dry burning" or liquid residue, affecting the stability of the refrigeration cycle. Therefore, these problems need to be solved. Utility Model Content

Example

[0016] refer to Figures 5 to 7A heat exchange structure includes a support plate fixed to the inner wall of one side of an air conditioner housing 1 and a heat exchanger installed at the bottom of the air conditioner housing 1. A condenser 6 is installed on the top of the support plate to facilitate rapid reduction of air temperature. A water storage box 9 is fixed to one side of the bottom inner wall of the air conditioner housing 1 to collect condensate guided by an inclined ceramic plate 8, providing a water source for a suction pump 10 and enabling the recycling of condensate. A suction pump 10 is installed at the bottom of the water storage box 9 to provide power for the heat exchanger's spray cooling, improving heat exchange efficiency. A spray rack 11 is provided on one side of the heat exchanger, with multiple nozzles evenly installed on the spray rack 11. An inclined ceramic plate 8 is fixed to the bottom of the support plate to guide condensed water droplets into the water storage box 9. A connecting pipe is provided between the bottom of the spray rack 11 and the suction pump 10. The spray rack 11 facilitates the atomization of condensate water and sprays it onto the surface of the heat exchanger, thereby reducing the temperature of the heat exchanger and improving the heat exchange efficiency. A water storage tank 7 is fixed to the other side of the inner wall of the air conditioner casing 1. The two ends of the water storage tank 7 are provided with connecting pipes for connecting the condenser 6 and the heat exchanger. The water storage tank 7 facilitates the storage of refrigerant required for the refrigeration cycle, provides a medium transmission guarantee for the condenser 6 and the heat exchanger, and also plays a role in buffering and stabilizing pressure. Air outlets 2 and air inlets 3 are respectively opened on the top two sides of the air conditioner casing 1. A fan 5 is installed on one side of the air outlet 2. The fan 5 facilitates the exchange of hot and cold air inside the air conditioner and pushes the cooled air out of the air outlet 2, thereby improving the cooling efficiency.

[0017] Working Principle: When using this utility model, the air conditioner casing 1 is first placed stably in the target area by the rollers 4 at the four corners of the bottom. The telescopic rod sleeve 12 and the inner rod 13 are at the user-suitable length for subsequent movement and adjustment. Then, each electrical component in this application is connected to the power supply. After starting the device, the fan 5 on the side of the air outlet 2 starts to operate. Under the negative pressure of the fan 5, external hot air enters the device through the air inlet 3 at the top of the air conditioner casing 1. At the same time, the refrigerant in the water tank 7 flows through the connecting pipes at both ends to the condenser 6 at the top of the support plate and the heat exchanger at the bottom, forming a closed loop. In the circulation process, after the condenser 6 is powered on, the cooling mode is activated. The refrigerant undergoes a phase change within the condenser 6, absorbing heat from the surrounding air during this process, rapidly reducing the temperature of the hot air entering the equipment. The suction pump 10 at the bottom of the water storage box 9 starts, and the suction pump 10 delivers the condensate to the spray rack 11 on one side of the heat exchanger through a connecting pipe. Multiple nozzles on the spray rack 11 atomize the condensate and spray it evenly onto the surface of the heat exchanger, lowering the heat exchanger temperature. The refrigerant flowing through the condenser 6 enters the heat exchanger and is further cooled by the low-temperature heat exchanger, ensuring that the refrigerant maintains its high-efficiency heat absorption capacity throughout its circulation to the condenser 6. After being cooled by the condenser 6, the air flows directionally towards the air outlet 2 at the top of the air conditioner casing 1 under the continuous power of the fan 5. The opening size of the air outlet 2 is adapted to the fan 5, with no obvious wind resistance, and the cold air is quickly discharged into the usage space to achieve regional cooling. Users can adjust the airflow direction of the air outlet 2 according to their needs to expand the coverage of the cold air and make the space temperature drop more evenly. At the same time, during the phase change heat absorption process of the condenser 6, the water vapor in the air condenses into water droplets, which drip onto the inclined ceramic plate 8 at the bottom of the support plate. The surface of the ceramic plate is smooth and it is designed to be inclined. Under the action of gravity, the water droplets... The water flows rapidly along the slope and eventually into the water storage box 9 on the inner wall of the bottom of the air conditioner casing 1, preventing water droplets from dripping and polluting the ground or damaging furniture. As the cooling process continues, the condensate in the water storage box 9 gradually increases. The suction pump 10 continuously delivers the condensate to the spray rack 11 to spray and cool the heat exchanger, forming a recycling process. Finally, after the equipment is turned off, the fan 5, condenser 6, and suction pump 10 stop operating simultaneously, the refrigerant stops circulating, and the air circulation ends. The spray rack 11 stops spraying, and the remaining condensate in the water storage box 9 can be stored for the next use. This concludes the use of a heat exchange structure and a portable air conditioner.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
