[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Reference Figures 1 to 2 A centralized cold storage vehicle-mounted refrigerator system includes: a vehicle-mounted thermal management system 1 and a cold storage unit 2. The cold storage unit 2 is connected to the vehicle-mounted thermal management system 1. The cold storage unit 2 includes an evaporator 21 and a second condenser 22. The evaporator 21 is connected to a first condenser 13 and a thermal management system outlet pipe 15. The system also includes a refrigerator 4, which is connected to the second condenser 22 to form a closed loop. During the downtime of the vehicle-mounted thermal management system 1, the second condenser 22 retains a portion of the cold energy absorbed from the evaporator 21. Therefore, the cold storage unit 2 can continue to provide cooling energy to the refrigerator 4, enabling the refrigerator 4 to continue cooling. Thus, the refrigerator 4 can continue to cool even after the vehicle has stopped and started.

[0022] In a preferred embodiment, the vehicle-mounted thermal management system 1 includes a liquid receiver 11 for storing refrigerant, a compressor 12 connected to the liquid receiver 11, a first condenser 13 connected to the compressor 12, a cold storage unit 2 connected to the first condenser 13, and a thermal management system inlet pipe 14 and a thermal management system outlet pipe 15. The thermal management system inlet pipe 14 is connected to the first condenser 13, and the thermal management system outlet pipe 15 is connected to the liquid receiver 11.

[0023] In a preferred embodiment, the cold storage unit 2 absorbs and stores heat through an evaporator.

[0024] In a preferred embodiment, the cold accumulator 2 contains a cold storage liquid, which is a solid-liquid mixture. Through the phase change process of the solid-liquid mixture, the effect of absorbing heat at low temperatures and releasing heat at high temperatures can be achieved.

[0025] In a preferred embodiment, an electronic expansion valve 3 is also included. The electronic expansion valve 3 is disposed between the first condenser 13 and the cold storage 2. The electronic expansion valve 3 is used to regulate the refrigerant flow pressure, so that the refrigerant is throttled and depressurized to reach the pressure required by the evaporator in the cold storage 2.

[0026] In a preferred embodiment, the refrigerator 4 includes a first refrigerator 411 and a second refrigerator 412 connected in parallel. There are multiple refrigerators 4, which can be installed in the front row, rear row, trunk, or other locations of a car.

[0027] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
