Description

Technical Field

[0001] The invention belongs to the field of oil-to-electric refrigeration systems for medium and heavy fuel truck refrigerated trucks, and specifically relates to a structure and a manufacturing process of a fully electric integrated refrigeration system suitable for medium and heavy fuel truck refrigerated trucks. Background Art

[0002] Traditional refrigerated trucks are generally equipped with independent refrigeration units. Their condensers integrate many large components such as small diesel engines, compressors, and heat exchangers, so they are quite large. During the assembly process, they often conflict with the high-top cab, and the top of the cab has to be cut and patched, which undoubtedly destroys the original structure of the roof. In this way, the driver's driving space is greatly reduced, and in subsequent use, it may also cause a series of difficult problems such as water leakage in the cab.

[0003] In addition, traditional refrigeration units rely on small diesel engines to power the compressor, or install a compressor in the original vehicle engine position. During normal operation, the fuel consumption is high, which significantly increases the operating cost of the refrigerated truck.

[0004] Furthermore, when using a combination of a refrigeration machine and a diesel engine or installing a compressor in the original vehicle engine position, the diesel engine or the original vehicle engine must remain started when the vehicle is parked. The strong noise generated during operation will not only interfere with the driver's normal rest and work, but also cause adverse noise pollution to the surrounding environment.

[0005] To this end, the present invention provides a structure and a manufacturing process for a fully electric integrated refrigeration system suitable for medium and heavy fuel truck refrigerated trucks. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: the structure and manufacturing process of a fully electric integrated refrigeration system suitable for medium and heavy-duty fuel refrigerated trucks described in the present invention include a fully electric integrated refrigeration system main body and a refrigerated vehicle body arranged at the rear end of the fully electric integrated refrigeration system main body. The fully electric integrated refrigeration system structure is composed of an on-board excitation generator, an integrated power supply system, a fully variable frequency electric refrigeration system, an electric parking air conditioner and a central control screen control system. The electric parking air conditioner is arranged on the top of the front of the fully electric integrated refrigeration system main body, the on-board excitation generator is arranged at the bottom of the front of the fully electric integrated refrigeration system main body, the central control screen control system is arranged in the front of the fully electric integrated refrigeration system main body, the bottom of the refrigerated vehicle body is arranged with an integrated power supply system, and the front end of the top of the fully electric integrated refrigeration system main body is arranged with a fully variable frequency electric refrigeration system.

[0008] Preferably, the integrated power supply system includes a battery module and a battery management system, a battery charging management module, and a battery high and low voltage discharge module and a distribution management system.

[0009] A manufacturing process of a fully electric integrated refrigeration system structure suitable for medium and heavy fuel refrigerated trucks includes the following steps: S1. Modify the on-board excitation generator to increase its power generation capacity, thereby providing sufficient power for the integrated power supply system, complete the installation of the integrated power supply system, and use professional testing equipment and debugging methods to conduct comprehensive and detailed debugging and precise calibration to ensure that all its electrical performance indicators meet the preset standards and achieve stable and reliable operation; S2. Install the full-frequency electric refrigeration system and electric parking air conditioner to the corresponding positions, and connect them to the integrated power supply system through the adapted lines, and conduct communication connection tests between the components. Use professional communication detection tools and software to strictly test the accuracy, completeness and timeliness of data transmission until the test results show that the communication connection between the components is completely normal and the data interaction is smooth and unimpeded; S3. Install the central control screen control system, use network communication technology and data acquisition modules to build a remote monitoring platform, through which various parameters of the entire refrigeration system operation process, such as temperature, humidity, power, equipment operating status, etc., can be remotely monitored in real time, and the collected data can be classified, stored, analyzed and processed to timely detect potential system failures or performance fluctuations, and then quickly make targeted responses and precise control measures to ensure that the refrigerated truck's fully electric integrated refrigeration system is always in an efficient and stable operating condition.

[0010] The beneficial effects of the present invention are as follows: 1. The structure and manufacturing process of the fully electric integrated refrigeration system suitable for medium and heavy fuel refrigerated trucks described in the present invention avoids the need to cut and damage the cab of traditional refrigerated trucks due to the installation of independent refrigeration units, thereby ensuring the integrity of the use space of high-top double-bed models. By adopting an on-board excitation generator, energy storage lithium battery pack and pure electric variable frequency refrigeration technology, the working mode mainly uses the energy storage lithium battery pack for charging and uses the on-board excitation generator for power generation and energy supplement as a supplement, so that there is no need for the original vehicle diesel engine to provide power, no direct fuel consumption cost, no long-term consumable operating cost, and reduces the direct operating cost of the refrigerated truck, while also improving the comfort and quietness of the use process.

[0011] 2. The structure and manufacturing process of the fully electric integrated refrigeration system suitable for medium and heavy fuel refrigerated trucks described in the present invention improves the power generation capacity by modifying the original vehicle's onboard excitation generator to increase the power generation capacity, and meets the power requirements of the fully electric integrated refrigeration system and electric parking air conditioner for a long time when the vehicle is parked and the engine is turned off. Through the central control screen control system, the present invention realizes remote monitoring and parameter setting of the refrigeration system, parking air conditioner and integrated power supply system, which is convenient for users to manage equipment and troubleshoot, collect data and provide a basis for subsequent optimization. Provide a use plan for the fully electric integrated refrigeration system, provide users with better refrigeration equipment supporting facilities, provide a better user experience, and reduce costs and increase efficiency in the entire logistics process.

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0015] like Figure 1 and Figure 2 As shown, a structure and manufacturing process of a fully electric integrated refrigeration system suitable for medium and heavy fuel refrigerated trucks of an embodiment of the present invention include a fully electric integrated refrigeration system main body 1 and a refrigerated vehicle body 2 arranged at the rear end of the fully electric integrated refrigeration system main body 1. The fully electric integrated refrigeration system structure is composed of a vehicle-mounted excitation generator 3, an integrated power supply system 4, a fully variable frequency electric refrigeration system 5, an electric parking air conditioner 6 and a central control screen control system. The electric parking air conditioner 6 is arranged on the top of the front of the fully electric integrated refrigeration system main body 1, the vehicle-mounted excitation generator 3 is arranged at the bottom of the front of the fully electric integrated refrigeration system main body 1, the central control screen control system is arranged in the front of the fully electric integrated refrigeration system main body 1, the bottom of the refrigerated vehicle body 2 is arranged with an integrated power supply system 4, and the front end of the top of the fully electric integrated refrigeration system main body 1 is arranged with a fully variable frequency electric refrigeration system 5.

[0016] The integrated power supply system 4 includes a battery module and a battery management system, a battery charging management module, and a battery high and low voltage discharge module and a distribution management system.

[0017] A manufacturing process of a fully electric integrated refrigeration system structure suitable for medium and heavy fuel refrigerated trucks includes the following steps: S1. Modify the on-board excitation generator 3 to increase its power generation capacity, thereby providing sufficient power for the integrated power supply system 4, complete the installation of the integrated power supply system 4, and use professional testing equipment and debugging methods to perform comprehensive and detailed debugging and precise calibration on it to ensure that its various electrical performance indicators meet the preset standards and achieve stable and reliable operation; S2. Install the full-frequency electric refrigeration system 5 and the electric parking air conditioner 6 to the corresponding positions, and connect them to the integrated power supply system 4 through the adapted lines, and conduct the communication connection test between the components. Use professional communication detection tools and software to strictly test the accuracy, completeness and timeliness of data transmission until the test results show that the communication connection between the components is completely normal and the data interaction is smooth and unimpeded; S3. Install the central control screen control system, use network communication technology and data acquisition modules to build a remote monitoring platform, through which various parameters of the entire refrigeration system operation process, such as temperature, humidity, power, equipment operating status, etc., can be remotely monitored in real time, and the collected data can be classified, stored, analyzed and processed to timely detect potential system failures or performance fluctuations, and then quickly make targeted responses and precise control measures to ensure that the refrigerated truck's fully electric integrated refrigeration system is always in an efficient and stable operating condition.

[0018] It should be noted here that By replacing the original vehicle-mounted excitation generator 3 and increasing its power generation capacity, this is used as one of the core energy input methods. At the same time, the roof is selected as the preferred solar installation location, and solar devices are also installed on the two side panels of the refrigerated truck. The two together serve as additional energy supplementary input sources. In addition, the mains 380VAC is introduced as another energy input method to provide sufficient power for the integrated power supply system 4 in all directions; The integrated power supply system 4 is responsible for managing and reasonably distributing the acquired electric energy. On the one hand, it outputs stable power to the full-frequency electric refrigeration system 5, and on the other hand, it provides power output to the electric parking air conditioner 6, and can provide DC-AC220V as output to meet other related power needs; An electric parking air conditioner 6 is installed on the top of the refrigerated truck, and the electric energy of the integrated power supply system 4 is used to realize direct drive operation, thus getting rid of many limitations of traditional drive methods. The central control screen control system plays an important role. It can be used to accurately set various parameters of the refrigeration system, parking air conditioner and integrated power supply system 4, and realize real-time monitoring of the remote operation status of these systems and comprehensive collection of relevant data, laying a solid foundation for the efficient operation, maintenance management and subsequent optimization and upgrading of the entire refrigerated truck.

[0019] The present invention effectively avoids the disadvantage that the independent refrigeration unit of a traditional refrigerated truck cuts and damages the cab due to its large size, effectively ensures the integrity of the original vehicle style of the high-top vehicle, and preserves the original vehicle design functionality intact.

[0020] With the application of pure electric variable frequency refrigeration technology and lithium battery energy storage, the present invention completely abandons the mode of separate diesel vehicle excitation generator 3 participating in the work, and there is no need to install a compressor at the original vehicle engine position, thereby greatly reducing the extent of modification of the original vehicle layout and system, and significantly reducing the direct operating cost of the refrigerated truck. At the same time, it effectively reduces the noise pollution generated by equipment and facilities, greatly improves the comfort during use, and achieves excellent quiet effect.

[0021] The present invention modifies the original vehicle-mounted excitation generator 3 and successfully increases its power generation capacity, fully meeting the power requirements of the fully electric integrated refrigeration system and the electric parking air conditioner 6 when the vehicle is in a parked and ignited state for a long time, thereby ensuring the stable operation of the system.

[0022] Through the use of the central control screen control system, the present invention achieves the remote monitoring and parameter setting functions of the refrigeration system, parking air conditioner and integrated power supply system 4, which provides great convenience for users in equipment management and troubleshooting. The collected data also provides a solid basis for subsequent system optimization.

[0023] The all-electric integrated refrigeration system usage solution provided by the present invention is intended to equip users with more excellent refrigeration equipment supporting facilities, create a better user experience, and thereby effectively achieve the goal of reducing costs and increasing efficiency in the entire logistics process, and effectively promote the technological progress and development of the refrigerated transportation industry.

[0024] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
