[0020] The following further describes the utility model with reference to the drawings and embodiments.
[0021] See Figures 1-3A side exhaust structure of a condenser heat dissipation system of a new energy vehicle refrigerator comprises a fan 2, a refrigeration device and an exhaust duct 3 arranged on a refrigerator body 1. The refrigerator body 1 is provided with a receiving cavity 4 for installing and accommodating the refrigeration device. The exhaust duct 3 is connected with an air suction port of the fan 2. The exhaust duct 3 is provided with an air inlet end 5 and an air outlet end 6. The air inlet end 5 of the exhaust duct 3 is connected with the receiving cavity 4, and the air outlet end 6 of the exhaust duct 3 is connected with the outside air. The heat generated by the refrigeration device in the receiving cavity 4 enters the exhaust duct 3 along the air inlet end 5 under the action of the air flow drawn by the fan 2 and is discharged out of the exhaust duct 3 through the air outlet end 6.
[0022] At least part of the fan 2 is built into the exhaust duct 3, and the exhaust duct 3 covers the part of the fan 2 to form a wind noise shielding part, which prevents the working noise of the fan 2 from being transmitted outward, and can prevent the vehicle refrigerator from generating a large noise when the vehicle is running.
[0023] The exhaust duct 3 includes a first duct 7 connected to the air intake port of the fan 2. The refrigeration device includes a condenser 8 installed in the first duct 7. The fan 2 draws heat generated by the condenser 8 through the first duct 7 to dissipate heat from the condenser 8.
[0024] The first air duct 7 covers the rotating part of the fan blade of the fan 2, and can effectively shield the noise generated by the fan blade driving the air flow movement when the fan 2 is running.
[0025] The exhaust duct 3 includes a first duct 7 and a second duct 9. The first duct 7 is horizontally arranged in the accommodating chamber 4, and the second duct 9 is arranged on the outside of the accommodating chamber 4. The suction port of the fan 2 is connected to the first duct 7, and the blowing port of the fan 2 is connected to the second duct 9. When the fan 2 is started, the airflow of the accommodating chamber 4 enters the first duct 7 and the second duct 9 in sequence.
[0026] The first air duct 7 is horizontally arranged in the accommodating chamber 4, the second air duct 9 is vertically arranged on the outside of the accommodating chamber 4, and the first air duct 7 is arranged close to the top wall of the accommodating chamber 4. The airflow in the accommodating chamber 4 enters the first air duct 7 from bottom to top under the suction action of the fan 2.
[0027] The refrigeration device includes a condenser 8, which includes a condenser tube spirally wound in a first air duct 7. An inclined guide wall 10 is provided in the first air duct 7 for guiding the air flow toward the air suction port of the fan 2. The heat generated by the condenser 8 flows through the fan 2 along the first air duct 7 to the second air duct 9.
[0028] In this embodiment, the condenser tube is spirally coiled in the first air duct 7 to increase the flow length of the heat exchange fluid and achieve the purpose of heat dissipation.
[0029] The distance between the two inner sides of the second air duct 9 gradually increases toward the air outlet end 6 of the exhaust duct 3 , thereby increasing the exhaust air volume of the second air duct 9 .
[0030] An inclined wall 11 and / or an arc wall 12 for guiding the air flow towards the air outlet end 6 of the exhaust air duct 3 are provided in the second air duct 9.
[0031] The refrigeration device includes a compressor 13 disposed in the accommodation cavity 4. The heat generated by the operation of the compressor 13 is discharged out of the accommodation cavity 4 along the exhaust air duct 3 by the fan 2. The exhaust air duct 3 includes a first air duct 7 located above the compressor 13 and a second air duct 9 on an outer side away from the compressor 13.
[0032] The refrigerator main body 1 is provided with an air inlet for connecting the outside air with the accommodation cavity 4, and the outside air enters the accommodation cavity 4 through the air inlet.
[0033] The position height of the air inlet on the refrigerator main body 1 is less than, greater than or equal to the position height of the air inlet end 5 on the refrigerator main body 1.
[0034] In this embodiment, if the position height of the air inlet on the refrigerator main body 1 is equal to the position height of the air inlet end 5 on the refrigerator main body 1, and the air inlet end 5 is provided on the first air duct 7, that is, the outside cold air preferentially enters the first air duct 7 and exchanges heat with the condenser 8 in the first air duct 7.
[0035] In this embodiment, a protective shell is provided in the accommodation cavity 4. The condensation pipe of the condenser 8 is coiled inside the protective shell. The protective shell has a hollow structure. One end of the protective shell communicates with the accommodation cavity 4, and the other end of the protective shell communicates with the suction port of the fan 2. The condensation pipe is coiled inside the protective shell, and the structure of providing heat dissipation fins on the condenser 8 is cancelled, effectively simplifying the structure of the condenser 8 and thus reducing the production cost.
[0036] In this embodiment, the refrigerator main body 1 may not need to be provided with an air inlet. The heat generated by the operation of the condenser 8 and the compressor 13 is continuously discharged out of the accommodation cavity 4 under the action of the fan 2, preventing excessive heat from accumulating in the accommodation cavity 4.
[0037] In this embodiment, if the position height of the air inlet on the refrigerator main body 1 is less than the position height of the air inlet end 5 on the refrigerator main body 1, since the first air duct 7 is provided above the compressor 13, after the cold air exchanges heat with the compressor 13, it enters the first air duct 7 from bottom to top, and can absorb the heat generated by the operation of the compressor 13 and the condenser 8.
[0038] In this embodiment, the refrigerator main body 1 includes a housing, the fan 2 includes a volute fixed on the outer side of the housing, and a recess for forming the second air duct 9 is provided on the outer side of the housing of the refrigerator main body 1.
[0039] In this embodiment, a sealing plate is provided on the housing of the refrigerator main body 1 corresponding to the recess. The sealing plate covers the recess, and the opening at the bottom of the recess forms the air outlet end 6 of the exhaust air duct 3.
[0040] In this embodiment, the second air duct 9 is arranged outside the accommodation cavity, so as to prevent the gas with the heat of the refrigeration device from returning to the accommodation cavity. The gas entering the first air duct 7 and the gas discharged outside the exhaust air duct 3 along the second air duct 9 do not interfere with each other, effectively dissipating the heat of the refrigeration device in the accommodation cavity 4.
