Description

Technical Field

[0001] The utility model relates to the technical field of air coolers, in particular to a carbon dioxide energy-saving and environment-friendly air cooler. Background Art

[0002] The refrigeration components of an air cooler generally include a compressor, a condenser, an expansion valve and an evaporator. The compressor compresses the gas refrigerant into a high-temperature and high-pressure gas, and then dissipates the heat of the gas through the condenser, causing its temperature to drop and convert into liquid. Then, the high-pressure liquid refrigerant enters the evaporator through the expansion valve. At this time, the pressure of the liquid refrigerant drops suddenly, and its temperature drops sharply. The heat is exchanged through the contact between the external air and the fins of the evaporator to blow out cooled air to the outside, thereby realizing the cooling operation of the air cooler.

[0003] During the cooling process of the air cooler, the outside air needs to be in contact with the fins at all times for heat exchange. The water vapor in the air tends to condense on the fins when it contacts the fins, causing frost to form on the fins more easily, thereby affecting the cooling efficiency of the air conditioner. Summary of the Invention

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and provide a carbon dioxide energy-saving and environment-friendly air cooler.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A carbon dioxide energy-saving and environmentally friendly air cooler includes a shell, in which a refrigeration component and a cold air box are installed, the fins of the refrigeration component are arranged in the cold air box, and a fan is installed on the air outlet of the cold air box. A filter plate and an air inlet component are arranged inside the cold air box, and the air inlet component, filter plate, fins and fan are distributed in sequence from the inside to the outside. The air inlet component includes an air inlet pipe and a heating pipe arranged on the periphery of the air inlet pipe.

[0007] Preferably, the air inlet assembly further includes a coil connected to the air inlet pipe, the coil is spirally extended outward, and a plurality of air outlets 2 are provided on the coil.

[0008] Preferably, the heating pipes are distributed along the extension path of the coil.

[0009] Preferably, the opening of the second air outlet is arranged toward the filter plate.

[0010] Preferably, the fins and the heating tubes are distributed on both sides of the filter plate, and the filter plate seals the air inlet assembly in the cold air box.

[0011] Preferably, the cold air box is provided with a back plate, the air inlet pipe passes through the back plate and extends inwardly, and the heating pipe is installed on the back plate.

[0012] Preferably, a fan cover for housing a blower is installed on the cold air box.

[0013] Preferably, heat dissipation holes are provided on the side of the shell.

[0014] Preferably, the refrigerant in the refrigeration assembly is carbon dioxide.

[0015] The beneficial effects of the utility model are:

[0016] 1. By arranging a heating tube on the periphery of the air inlet pipe, when the air inlet pipe conveys air into the cold air box, the air in the air inlet pipe is heated by the heating tube, which effectively reduces the water vapor content in the air, making the air blowing to the fins drier, thereby reducing problems such as fin frosting, greatly improving the cooling performance of the air cooler, saving the electricity required for cooling, and making the use of the air cooler more energy-saving and environmentally friendly;

[0017] 2. By setting a filter plate between the fins and the air inlet pipe, the heated air is filtered through the filter plate, further reducing the water vapor content in the air. The transition of air transportation is carried out through the filter plate to avoid direct contact of hot air with the fins, resulting in waste of fin cooling temperature, thereby improving energy utilization;

[0018] 3. Carbon dioxide is used as a refrigerant. Compared with other refrigeration media, carbon dioxide refrigeration is more hygienic and safer for frozen food, and in the event of an accidental leak, it will not pollute the environment and is more environmentally friendly.

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0027] like Figures 1 to 5 As shown, the carbon dioxide energy-saving and environmentally friendly air cooler includes a shell 1, in which a refrigeration component 11 and a cold air box 13 are installed. The refrigeration component 11 includes a compressor, a condenser, an expansion valve and an evaporator. The refrigeration operation of the refrigeration component 11 is a prior art and will not be described in detail here. A heat dissipation hole 15 is provided on the side of the shell 1, and the heat dissipation hole 15 is convenient for dissipating the heat of the refrigeration component 11 when it is working.

[0028] The refrigerant in the refrigeration assembly 11 is carbon dioxide. Compared with other refrigeration media, carbon dioxide refrigeration is more hygienic and safer for frozen food, and will not pollute the environment in the event of an accidental leak, which is more environmentally friendly.

[0029] The fins 12 of the refrigeration component 11 are arranged in a cold air box 13, and a fan 2 is installed on the air outlet 131 of the cold air box 13. A fan cover 21 for covering the fan 2 is installed on the cold air box 13. The fan 2 and the fins 12 are arranged relative to each other inside and outside through the air outlet 131. Through the operation of the fan 2, the air flows and contacts the fins 12 for heat exchange, and then the cold air is blown out.

[0030] The cold air box 13 is provided with a filter plate 3 and an air inlet assembly 4. The air inlet assembly 4, the filter plate 3, the fins 12 and the fan 2 are distributed in sequence from the inside to the outside. The filter plate 3 is fitted in the cold air box 13 so that the air inlet assembly 4 is sealed in the cold air box 13 through the filter plate 3.

[0031] The air inlet assembly 4 includes an air inlet pipe 41 and a heating pipe 44 arranged on the periphery of the air inlet pipe 41. The air inlet pipe 41 is used to transport air into the cold air box 13. By arranging the heating pipe 44 on the periphery of the air inlet pipe 41, when the air inlet pipe 41 transports air into the cold air box 13, the air in the air inlet pipe 41 is heated by powering through the heating pipe 44, which effectively reduces the water vapor content in the air, making the air blown to the fins 12 drier, thereby reducing problems such as frosting of the fins 12, greatly improving the refrigeration performance of this embodiment, saving the electricity required for refrigeration, and making this embodiment more energy-efficient when refrigerating the same cooling capacity, reducing energy loss and being more environmentally friendly.

[0032] The air inlet assembly 4 also includes a coil 42 connected to the air inlet pipe 41. The coil 42 extends outward in a spiral shape. A plurality of second air outlets 43 are opened on the coil 42. The second air outlets 43 are arranged on the outermost coil 42. The heating tube 44 is distributed along the extension path of the coil 42. The arrangement of the coil 42 increases the time for the air to be heated and dried by the heating tube 44, thereby reducing the water vapor content in the transported air.

[0033] The opening of the second air outlet 43 is arranged toward the filter plate 3, and the fins 12 and the heating tubes 44 are distributed on both sides of the filter plate 3. The heated air is filtered by the filter plate 3, further reducing the water vapor content in the air, and the transition of air transportation is performed through the filter plate 3 to avoid direct contact of the hot air with the fins 12, resulting in waste of the cooling temperature of the fins 12, thereby improving energy utilization.

[0034] Since the fins 12 are provided on one side of the filter plate 3, that is, the side of the filter plate 3 close to the fins 12 and having a lower temperature, as the air passes through the filter plate 3 and is transported to the side of the fins 12, the temperature of the air which was originally at a higher temperature will gradually decrease, thereby pre-cooling the air, improving the efficiency of subsequent air contact refrigeration, and saving the energy required for refrigeration.

[0035] A door panel 14 is installed on the front side of the housing 1 , and the door panel 14 can be rotated to open the housing 1 to facilitate regular replacement of the filter plate 3 .

[0036] The cold air box 13 is provided with a back plate 132, and the back plate 132 is used to close one side of the cold air box 13. The air inlet pipe 41 passes through the back plate 132 and extends inward. The heating pipe 44 is installed on the back plate 132, and the air inlet pipe 41 and the heating pipe 44 are installed and fixed through the back plate 132.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
