[0019] Please see Figures 1 to 7 The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0020] like Figure 1 and Figure 3 As shown, this utility model provides a cold chain unit for an unmanned transport vehicle, which includes a condenser assembly 100 and an evaporator assembly 200. The condenser assembly 100 is installed on the top of the vehicle compartment, and the evaporator assembly 200 is installed inside the vehicle compartment.

[0021] like Figure 2 and Figure 3As shown, the condensation assembly 100 includes a first housing 101, with through holes 102 on the top wall and side walls of the first housing 101. The first housing 101 has a first receiving cavity, which can be divided into a first chamber 103 and a second chamber 104.

[0022] like Figure 1 and Figure 2 As shown, the condensing assembly 100 further includes a gas-liquid separator 109, a compressor 105, an oil separator 106, a dryer filter 108, a first fan 110, and a condenser 107. The gas-liquid separator 109, compressor 105, oil separator 106, and dryer filter 108 are located in the first chamber 103, while the first fan 110 and condenser 107 are located in the second chamber 104. Specifically, the condenser 107 is located at the bottom of the first fan 110 and is a coil structure. Multiple side walls of the first housing 101 where the first fan 110 is located are provided with through holes 102, allowing the first fan 110 to be inclined within the second chamber 104.

[0023] The dryer filter 108 is used to absorb moisture in the refrigeration system and block impurities in the system from passing through, preventing ice blockage and dirt blockage in the refrigeration system pipelines. The oil separator 106 is usually installed on the discharge pipeline of the compressor 105 to separate the lubricating oil carried in the discharge of the compressor 105.

[0024] like Figure 1 As shown, one end of the gas-liquid separator 109 is connected to one end of the compressor 105, the other end of the compressor 105 is connected to one end of the oil separator 106, the other end of the oil separator 106 is connected to one end of the condenser 107, the condenser 107 can be a microchannel condenser 107, and the other end of the condenser 107 is connected to one end of the dryer filter 108.

[0025] like Figure 1 and Figure 7 As shown, the evaporation assembly 200 includes a second housing 201, a solenoid valve 203, an expansion valve 204, an evaporator 205, a second fan 207, and a heat exchanger 206. The second housing 201 has a second receiving cavity. An expansion valve 204 is provided at one end of the second receiving cavity. One end of the expansion valve 204 is connected to the dryer filter 108, and the other end of the expansion valve 204 is connected to one end of the evaporator 205. The evaporator 205 is a serpentine coil, and the other end of the evaporator 205 is connected to the other end of the gas-liquid separator 109.

[0026] In some embodiments, the evaporation assembly 200 further includes a heat exchanger 206, which can be a heat exchange tube. The heat exchanger 206 performs heat exchange, primarily by using the heat from the high-temperature, high-pressure refrigerant gas discharged from the compressor to preheat the low-temperature, low-pressure refrigerant gas drawn into the compressor, thereby reducing compressor power consumption and improving refrigeration efficiency. The heat exchanger 206 can be a heat exchange tube, with the pipeline connecting the expansion valve 204 and the dryer filter 108 exchanging heat with the pipeline connecting the evaporator 205 and the gas-liquid separator 109 in the heat exchanger 206. The two inlet ends of the heat exchanger 206 are respectively connected to the dryer filter 108 and the evaporator 205, and the two outlet ends are respectively connected to the expansion valve 204 and the gas-liquid separator 109.

[0027] The other end of the second receiving cavity is provided with a solenoid valve 203, which may be a defrosting solenoid valve. One end of the solenoid valve 203 is connected to the pipeline between the oil separator 106 and the condenser 107, and the other end of the solenoid valve 203 is connected to the pipeline between the expansion valve 204 and the evaporator 205.

[0028] like Figure 4 As shown, a vent 202 is provided on the second housing 201. The evaporator 205 can be disposed between the vent 202 and the second fan 207. There can be two second fans 207, and each second fan 207 is a brushless fan. The second fans 207 are inclinedly disposed within the second receiving cavity. The second fans 207 are located between the evaporator 205 and the heat exchanger 206. The evaporator 205, the second fans 207, and the heat exchanger 206 can be located between the solenoid valve 203 and the expansion valve 204.

[0029] like Figure 2 As shown, the cold chain unit also includes a high-pressure controller 301, a low-pressure relay 302, and a DC / DC module 303. The high-pressure controller 301, the low-pressure relay 302, and the DC / DC module 303 can be disposed within the first chamber 103. The high-pressure controller 301 can be electrically connected to the DC / DC module 303, and the DC / DC module 303 can be electrically connected to the low-pressure relay 302. The low-pressure relay 302 can be electrically connected to the first fan 110 and the second fan 207. The high-pressure controller 301, the low-pressure relay 302, and the DC / DC module can all include a housing, and the relevant electrical components are disposed within the housing. This facilitates installation and maintenance and achieves a certain level of waterproofing. Specifically, the housing is disposed on the inner wall of the first chamber 103.

[0030] The high-voltage controller 301 is model AOBO-PDU-001, the low-voltage relay 302 is model JZC-32F, the part numbers of the high-voltage controller 301 and the low-voltage relay 302 can be 4.3.6.11.1823, and the DC / DC module 303 is model ZWDC800-96-24-0-1.

[0031] The high-voltage controller 301 is responsible for the distribution and protection of high-voltage electricity, the low-voltage relay 302 is used for signal conversion and control protection circuits, and the DC / DC module 303 is responsible for the conversion of high-voltage to low-voltage electrical energy.

[0032] In operation, this utility model is fixed to the vehicle compartment via mounting holes on the left and right sides of the first housing 101. The condenser assembly adopts a windward design, utilizing the airflow generated by the vehicle's movement for heat dissipation, thus improving the condenser assembly's heat dissipation effect. All electrical components employ a modular design for easy installation. The evaporator assembly is located inside the vehicle compartment, delivering cool air into the compartment to control the interior temperature. The second fan uses two 9-inch fans to ensure sufficient airflow.

[0033] In the refrigeration system, low-pressure refrigerant vapor is drawn into the compressor and converted into high-pressure vapor before entering the condenser assembly. The condenser fan removes heat from the refrigerant within the condenser. The refrigerant, now a high-pressure liquid, flows out of the condenser, passes through a throttling device, and enters the evaporator. After low-pressure evaporation, it absorbs heat from the surrounding environment. The evaporator fan continuously exchanges air with the refrigerant, delivering cool air into the compartment, thus achieving temperature control within the unmanned refrigerated transport vehicle.

[0034] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
