Description

Technical Field

[0001] The utility model relates to the technical field of household air conditioners, in particular to a mobile air conditioner based on TEC. Background Art

[0002] At present, household air conditioning refrigeration is mainly through compressor refrigeration, which changes the state of refrigerant through mechanical energy to transfer heat from low-temperature objects to high-temperature environments. Compressors are mainly divided into semi-closed piston compressors, rotor refrigeration compressors, scroll refrigeration compressors, screw refrigeration compressors and centrifugal refrigeration compressors. Most mobile air conditioners use rotor refrigeration compressors, which have the advantages of simple structure, small size and light weight, compact size, small vibration during operation, and stable operation. The disadvantages are that the refrigeration capacity is not high compared with other types of compressors, the system cleanliness requirements are high, the processing accuracy requirements are high, the wear between the vane and the cylinder is large, and the performance is significantly reduced. Therefore, without changing the advantages of compressor refrigeration, designing a mobile air conditioner with higher refrigeration capacity and more stable performance than compressor refrigeration is a problem that technicians need to solve.

[0023] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example 1

[0025] The present embodiment provides a mobile air conditioner based on TEC, comprising a radiator assembly 1 and an air purification device 2, characterized in that: the radiator assembly 1 comprises an aluminum heat exchanger 13 and a diamond aluminum heat exchanger 15 arranged at an air outlet inside the air conditioner, a TEC cooling sheet 14 arranged between the aluminum heat exchanger 13 and the diamond aluminum heat exchanger 15, a diamond aluminum heat sink for the hot end of the TEC cooling sheet 14, a fan 12 arranged at the rear side of the aluminum heat exchanger 13, a water tank 3 and a water pump 8 located outside the water tank 3;

[0026] A proper amount of water is added to the water tank 3, and the temperature of the water storing 4000J of heat does not rise by more than 3°C. A water channel baffle 9 is provided in the water tank 3, and the water channel baffle 9 contacts the fins of the diamond aluminum heat sink to form a water channel. The water tank is provided with a water channel inlet 10 and a water tank outlet 11. The fins of the diamond aluminum heat sink keep water flowing through during operation, and the other side contacts the TEC refrigeration plate 14. Cold water / hot water are respectively injected into the water tank 3 in the cooling / heating mode of the air conditioner. Taking the cooling mode of the air conditioner as an example, the hot surface of the TEC refrigeration plate exchanges heat with the diamond aluminum heat sink, and the heat is transferred to the fins. The fins exchange heat with the water to maintain the temperature within the range of high cooling efficiency of the TEC refrigeration plate. After running for a long time, the water in the water tank 3 should be replaced, otherwise the efficiency of heat exchange will be affected.

[0027] The passing water is used to exchange heat with the fins of the diamond aluminum heat exchanger 15. The smooth side of the aluminum heat exchanger 13 contacts the cold end of the TEC refrigeration plate 14 for heat exchange. The fin temperature is reduced, and the fin exchanges heat with the air in the air conditioner to form the cold air to be blown out by the air conditioner.

[0028] The TEC cooling sheet 14 is used to adjust the heat distribution. The current direction in the TEC cooling sheet 14 is changed to adjust the cooling and heating state of the TEC cooling sheet 14. Insulating materials are added around the TEC cooling sheet 14 to prevent heat transfer between the cold and hot ends, which affects the cooling efficiency.

[0029] When the air conditioner is in cooling mode, the hot end of the TEC refrigeration plate 14 contacts the diamond aluminum heat exchanger 15, the cold end of the TEC refrigeration plate 14 contacts the aluminum heat exchanger 13, and the cold end contacts the aluminum radiator. At this time, the air conditioner blows out cold air, and the room temperature thermal conductivity of the diamond aluminum heat exchanger is greater than 500W / mK.

[0030] When the air conditioner is in heating mode, the cold end of the TEC refrigeration plate 14 contacts the diamond aluminum heat sink, the hot end of the TEC refrigeration plate 14 contacts the aluminum heat exchanger 13, and the hot end contacts the aluminum heat exchanger. At this time, the air conditioner blows out hot air.

[0031] When the diamond aluminum heat sink fins exchange heat with the water in the water tank, the water temperature near the fins changes quickly, while the water temperature in other parts changes slowly, resulting in uneven water temperature. The water is made to flow through the water pump 8, and the water in the lower part of the water tank 3 is pumped to the upper part through the water pump inlet pipe 4 and the water pump outlet pipe 6 to exchange heat with the fins of the diamond aluminum heat exchanger 15. The water that has undergone heat exchange flows out through the water channel, achieving uniform water temperature, extending the effective operation time of the air conditioner, and is used for hot and cold circulation of the water in the water tank 3.

[0032] The fan 12 is used to blow the air in the aluminum heat exchanger to the outside of the air conditioner. The fins form an air duct. The air exchanges heat with the fins when passing through the air duct and is then blown out of the air conditioner. The air volume of the fan can be changed by adjusting the voltage applied to the fan.

[0033] The air conditioning system also includes an outer frame 5, which is used to accommodate various components in the air conditioner. Wheels are installed on the outer frame 5. The outer frame 5 should be made of a light, easy-to-clean, and high-strength material to reduce the weight of the mobile air conditioner and make it more labor-saving when moving.

[0034] The air conditioning system also includes an air purification device 2, which includes a U-shaped transition piece, an anode copper needle 17, a shell 18 and a drive circuit. The U-shaped transition piece, the drive circuit and the anode copper needle 17 are all arranged in the shell 18. When the device is running, condensed water is generated on the U-shaped transition piece. The condensed water is ionized to produce charged water ions, and the charged water ions are used to adsorb harmful components in the air.

[0035] The U-shaped transition piece is composed of a first copper tube 19, a second copper tube 21, PN type particles 20, a first transition piece 16 and a second transition piece 22. When the device is running, the PN type particles 20 increase the temperature of the first copper tube 19 and the second copper tube 21 at both ends due to the Seebeck effect, and reduce the temperature of the first transition piece 16 and the second transition piece 22 in the middle. When the temperature of the first transition piece 16 and the second transition piece 22 is reduced to a certain extent, condensed water is generated on the sphere in the middle of the first transition piece 16 and the second transition piece 22. The anode copper needle 17 has a high voltage, and the condensed water will be ionized into OH negative ions for air purification.

[0036] Among them, the diamond aluminum material has a higher heat exchange coefficient than ordinary aluminum or copper materials. The diamond aluminum heat exchanger 15 can exchange heat with water faster and maintain high performance operation of the air conditioner.

[0037] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
