Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a cooling fan. Background Art

[0002] At present, there is a mobile air conditioner, comprising an air conditioner housing, rollers are installed on the four corners of the bottom of the air conditioner housing, a display screen and a control panel are installed outside the air conditioner housing, the air conditioner housing is divided into an upper layer, a middle layer and a bottom layer, a motor is installed in the upper layer, the motor is connected with a swing leaf and an evaporator, an air outlet is opened on the front of the upper layer, a condenser is installed in the middle layer, an exhaust port and an air inlet are opened on the back of the middle layer, a combined air duct is arranged between the evaporator and the condenser, and a compressor and a water tank are installed in the bottom layer. When working, cold air is generated in the upper layer, warm air is generated in the middle layer, water generated by the evaporator flows into the water tank, and water can be sprayed on the top of the condenser by a water pump in the water tank to absorb the heat generated by the condenser, and then flows into the water tank, a part of the water will evaporate into the air, which can increase the humidity of the air and improve the working effect of the condenser, so that the refrigerant in the evaporator is more fully vaporized and absorbs more heat in the upper layer. The above structure has the following shortcomings: 1. The water pump in the water tank sprays water on the condenser. The water is sprayed directly on the condenser to absorb the heat generated by the condenser. This cooling effect is poor, and the water will flow out of the mobile air conditioner when spraying, affecting normal use. 2. The refrigeration of the mobile air conditioner only relies on the refrigeration of the evaporator itself, and the refrigeration efficiency is low.

[0003] A mobile air conditioner with a water circulation system is also disclosed, comprising a compressor, a condenser, a heat exhaust fan wheel and a water collecting pan located in an air conditioner casing; the water collecting pan is arranged below the condenser; and also comprises a water circulation system located in the air conditioner casing; the water circulation system comprises a water pump, a drain pipe, a water cooling sleeve and a cooling pipe; the water pump is installed in the water collecting pan; the water inlet end of the drain pipe is connected to the water pump, and the water outlet end is connected to the water cooling sleeve; the compressor exhaust pipe of the compressor extends into the water cooling sleeve; one end of the cooling pipe is connected to the water cooling sleeve, and a plurality of water sprinkling holes are arranged on its surface. The water circulation mechanism inserts the compressor exhaust pipe into the water cooling sleeve, and at the same time introduces the cold water in the water collecting pan into the water cooling sleeve, the cold water performs heat exchange with the high-temperature refrigerant in the compressor exhaust pipe, the hot water after the heat exchange enters the cooling pipe, the water flows down through the plurality of water sprinkling holes on the cooling pipe, and the hot water itself is rapidly cooled by utilizing the heat absorption principle of water evaporation, and the cooled water enters the water collecting pan again, thereby forming a recycling of water. In this way, the high-pressure and high-temperature steam compressed by the compressor will not be discharged directly into the condenser, but will undergo heat exchange with cold water. The high-temperature steam formed by the compressor has been cooled, and the temperature of the condenser itself will not be too high even when it is working for a long time. It needs to be sprayed with cold water to cool down, and its heat dissipation and condensation effect can be maintained in a good state. The water circulation mechanism inserts the compressor exhaust pipe into the water-cooling sleeve, and at the same time introduces the cold water in the water collection tray into the water-cooling sleeve. The cold water exchanges heat with the high-temperature refrigerant in the compressor exhaust pipe, and the hot water after the heat exchange enters the cooling pipe. The cold water in the water collection tray is not additionally cooled in the process of being sent to the cooling pipe, so that the water temperature of the water coming out of the cooling pipe is not low enough, and the water coming out of the water collection tray does not cool the blown wind, so that the cooling effect of the air outlet of the air conditioner is low.
