Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, and in particular to a low-energy vehicle refrigerator. Background Technology

[0002] Car refrigerators are portable refrigerators that can be carried in cars. They are a new generation of refrigeration and cold storage appliances that have become popular in the international market in recent years. There are two main types of car refrigerators on the market: one is a semiconductor car refrigerator, which relies on electronic chips for cooling. It has a poor cooling effect but low energy consumption. The other is a compressor car refrigerator, which uses traditional refrigerator technology. It has a low cooling temperature of -18 degrees Celsius to 10 degrees Celsius, high cooling efficiency but high energy consumption.

[0003] For example, patent CN214215562U discloses an ultralight vehicle refrigerator, including a cabinet and a door rotatably mounted on the cabinet. A compressor compartment is provided at the bottom of the cabinet. The ultralight vehicle refrigerator has a compressor assembly installed in the compressor compartment. A blown evaporator is provided inside the cabinet. The compressor assembly is connected to the blown evaporator. The blown evaporator can be made by a blown process, which has high manufacturing flexibility and is suitable for refrigerators of different shapes and sizes. It has a compact structure, occupies less space, and is suitable for installation in limited refrigerator space.

[0004] The problem with the above technology is that cars usually generate electricity through the engine or battery to power the car refrigerator. However, the energy consumption of the compressor car refrigerator is relatively high, which requires a lot of energy from the car. Especially for electric vehicles, range is a key issue that car companies need to solve nowadays, and the energy consumption of the car refrigerator affects the range of electric vehicles.

[0005] Therefore, a low-energy vehicle refrigerator is proposed to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a low-energy-consumption vehicle refrigerator. By increasing the air flow rate on the surface of the evaporator through a fan, the evaporation efficiency can be significantly improved, the evaporation time can be shortened, and the energy consumption can be reduced, while improving the overall performance and efficiency of the vehicle refrigerator.

[0007] The technical solution adopted by this utility model to solve the problem is: a low-energy vehicle refrigerator, including a shell with a front opening, an inner liner with a front opening fixedly disposed inside the shell, a storage box with an upper opening movably disposed inside the inner liner, a compressor assembly fixedly disposed at the rear end of the shell, a suction-expansion evaporator connected to the compressor assembly disposed on the outer side wall of the inner liner, and a fan disposed on the inner side wall of the rear end of the inner liner.

[0008] As a further improvement to the above technical solution, an inwardly recessed mounting groove is provided on the inner wall of the rear end of the inner liner, the fan is installed in the mounting groove, and a panel is detachably connected to the opening of the mounting groove. The panel is provided with an air inlet and an air outlet, the air inlet is connected to the air inlet end of the fan, and the air outlet is connected to the air outlet end of the fan.

[0009] As a further improvement to the above technical solution, the air outlet is located above the air inlet, and the air outlet faces the top of the inner liner.

[0010] As a further improvement to the above technical solution, the height of the storage box is lower than the height of the panel.

[0011] As a further improvement to the above technical solution, a bracket is fixedly provided at the rear end of the housing, and the compressor assembly is fixedly mounted on the bracket.

[0012] The beneficial effects of this invention are as follows: After the low-temperature, low-pressure liquid refrigerant enters the blown evaporator, it evaporates inside the blown evaporator, absorbs heat from the inner liner, and becomes gaseous, thus lowering the temperature inside the inner liner. Subsequently, the refrigerant is drawn into the compressor assembly and circulates. In the operation of the vehicle refrigerator, the airflow velocity on the surface of the blown evaporator can be increased by a fan, which can significantly improve evaporation efficiency, shorten evaporation time, and reduce energy consumption. At the same time, it improves the overall performance and efficiency of the vehicle refrigerator, reduces the energy consumption of the car, and thus improves the car's range.

Subsequently, the refrigerant is drawn into the compressor assembly 4 and circulates. During the operation of the vehicle refrigerator, the airflow velocity on the surface of the blown evaporator 5 can be increased by the fan 6, which can significantly improve the evaporation efficiency, shorten the evaporation time, and reduce energy consumption.
