Description

Technical Field

[0002] As a convenient refrigeration device, mobile air conditioners are widely used in homes, offices and other places. Compared with traditional fixed air conditioners, mobile air conditioners have the advantages of not being restricted by installation location and being easy to move.

[0003] The heat generated by the mobile air conditioner during operation needs to be effectively dissipated to ensure the efficient operation and long life of the equipment. The heat dissipation structure design of the mobile air conditioner on the market is relatively simple, and there are problems such as low heat dissipation efficiency and imperfect condensate treatment, which affect the overall performance of the mobile air conditioner. Existing mobile air conditioners usually dissipate heat through a single heat sink group. This design has certain limitations in heat dissipation efficiency, especially when the ambient temperature is high, the heat dissipation effect is not good. In addition, the treatment method of condensate is also relatively simple. Most of them rely on the chassis to collect directly, which is easy to cause condensate overflow or accumulation, resulting in excessive humidity inside the equipment, thus affecting the normal operation of the air conditioner; therefore, some mobile air conditioners on the market use a water tray to catch the condensate, and pump up the condensate so that the water adheres to the condenser to improve the heat dissipation efficiency, but this type of heat dissipation mechanism is prone to water splashing onto the outer shell when pumping water, and then leaking out of the outer shell, polluting the external environment.

[0025] A heat dissipation structure of a mobile air conditioner, see Figure 1-4, including a shell 100 and a heat exchange component including a condenser 200. Generally, the heat exchange component also includes an evaporator, a compressor, etc., which is a prior art and will not be described in detail. A chassis 120 is provided in the shell 100, and the chassis 100 is connected to the bottom of the shell 100. A water receiving tank 121 for loading condensed water is formed on the chassis 120. A water pumping device 130 is provided on the chassis 120. The water pumping device 130 includes a motor 131 and a rotating wheel 122 located in the water receiving tank 121. The motor 131 can drive the rotating wheel 122 to rotate to pump the water receiving tank 1 The water in 21 is attached to the condenser 200. Since the temperature of the condenser 200 is high, the water is heated to form water vapor. The condenser 200 is provided with a first heat sink group 210 and a second heat sink group 220. The runner 122 is located between the first heat sink group 210 and the second heat sink group 220. Therefore, after the runner 122 beats up the water, it will be attached to the first heat sink group 210 and the second heat sink group 220 at the same time. The two heat sink groups act at the same time to accelerate the heat dissipation efficiency. The two sides of the condenser 200 are respectively provided with a first heat sink group 210 and a second heat sink group 220. The water baffle 230 is disposed on the same side of the first heat sink group 210 and the second heat sink group 220, and the water baffle 230 prevents the water splashed by the rotating wheel 122 from splashing out from the position between the first heat sink group 210 and the second heat sink group 220; the water baffle 230 is provided with an extension portion 231 extending outward and beyond the first heat sink group 210 on the side close to the first heat sink group 210, and the extension portion 231 is a part of the water baffle 230. Since the water pumping device 130 is disposed on the side of the first heat sink group 210 away from the second heat sink group 220, it is possible that the rotating shaft of the motor 131 rotates Water will be splashed on the front side of the first heat sink group 210. In addition, due to the small width of the first heat sink group 210, the wheel 122 may also pump water and pass through the front side of the first heat sink group 210 when pumping water. When water splashes to both sides of the front end of the first heat sink group 210, the extension part 231 can block the water, and the blocked water directly drips into the water receiving groove 121, thereby preventing the water from splashing onto the inner wall of the outer shell 100 and then flowing downward and out of the outer shell 100. The extension part 231 effectively prevents the mobile air conditioner from leaking and polluting the external environment.

[0026] Furthermore, the water receiving grooves 121 are distributed on three adjacent sides of the chassis 120. Compared with the prior art, the water receiving grooves 121 are distributed on multiple sides, with a larger water capacity, which can store more condensed water, and can avoid the water shortage in the water receiving groove 121 and the decrease in heat dissipation effect; the first heat sink group 210 and the second heat sink group 220 are respectively composed of multiple heat sinks, and the heat sink density on the first heat sink group 210 is greater than that on the second heat sink group 220. The larger density can further prevent water from splashing out of the first heat sink group 210 away from the side of the second heat sink group 220 when water is poured. The heat sink width on the second heat sink group 220 is greater than that of the first heat sink group 210. Heat sinks with larger widths have higher heat dissipation efficiency. The first heat sink group 210 and the second heat sink group 220 have different structures to play a certain role in splashing water and ensure heat dissipation efficiency.

[0027] Furthermore, the motor 131 is fixed on the chassis 120 and is located outside the water receiving groove 121. The rotating shaft on the motor 131 extends in the direction of the water receiving groove 121 and is connected to the rotating wheel 122. The fixed position of the motor 131 can prevent contact with the water in the water receiving groove 121, thereby preventing the motor 131 from being damaged by water. The housing 100 is provided with an exhaust hood 300 that connects the inside and outside of the housing 100. The exhaust hood 300 is provided with a wind wheel 310 that can extract the air in the housing 100 to the outside. The exhaust hood 300 extracts the hot air evaporated by the condenser 200 out of the housing 100 to improve the heat dissipation efficiency. The outside of the chassis 120 is provided with a water outlet 123 that protrudes from the outside of the housing 100. The water outlet 12 The water receiving tank 121 is connected to the outside of the chassis 120, and the water outlet 123 is used to discharge the excessive condensed water in the water receiving tank 121 to the outside; the water receiving tank 121 is provided with a plurality of partitions 124 connected to the bottom of the condenser 200, and the partitions 123 are provided with a plurality of water holes for connecting therein, and the water holes ensure that the condensed water can flow between the partitions 123, and the partitions 123 can prevent the water in the water receiving tank 121 from overflowing due to excessive fluctuations when pumping water; the housing 100 is provided with a vent hole 140 on the side close to the condenser 200, and the vent hole 140 ensures that the air outside the housing 100 can enter the inside normally, and cooperates with the exhaust of the exhaust hood 300 to make the air circulate.
