Description

Technical Field

[0001] The present invention belongs to the field of cold chain transportation, and specifically relates to a thermal energy supply and management system for logistics transportation vehicles. Background Art

[0002] The electrification of transportation is one of the main measures to address the huge challenges of environmental pollution and climate change. In recent years, the electric vehicle market has developed rapidly. At present, the thermal energy (heat and cold) inside electric vehicles is mostly provided through on-board air conditioning and electric heating elements, which consume a lot of power batteries. When heating in winter in cold areas, some models need to occupy more than 50% of the battery power, which greatly affects the mileage of electric vehicles. At present, the solution to this problem is to use a more efficient heat pump system for heating. However, the heat pump system still consumes more than 20% of the electricity of the electric vehicle, and the heat pump system has the problem of a sharp drop in working efficiency in extremely cold environments (below -10°C).

[0003] Refrigeration electrification is one of the solutions to reduce carbon dioxide emissions, but electric cold chain transport vehicles also have the problem of battery power usage due to the need to continuously provide cooling for transported goods, which affects the driving range. In addition, in cold regions, logistics transportation, especially fresh fruits, vegetables and flowers, requires heating rather than refrigeration to ensure that the products are not frozen. Therefore, electric vehicles and logistics transport vehicles need a new energy supply system to provide heat and cold energy. Summary of the invention

Example 1

[0043] like Figure 2As shown, it is a schematic diagram of a heat supply and management system for logistics transportation vehicles with heating and primary cooling functions based on thermochemical energy storage. The system generally includes a thermochemical reactor 101, and the filling material is a mixture of silica gel and graphite with a mass ratio of 9:1. When the thermochemical reactor 101 needs to be charged, the blower 2 starts to work, and the air enters from the air inlet 1 and reaches the inlet of the four-way valve 3 through the conduit. The four-way valve 3 has three outlets, which are respectively connected to the humidifier 100, the first heat exchanger 4 and the eighth three-way valve 116 through the conduit. At this time, the outlet to the first heat exchanger 4 is opened, and the air in state ① reaches the first heat exchanger 4 through the conduit. At this time, the air in state ④ flowing out of the thermochemical reactor 101 passes through the first heat exchanger 4, and the air in state ① is heated to reach state ②. The electric heating unit 5 is connected to the first heat exchanger 4 through a conduit, and its built-in temperature sensor reads the temperature of the passing air in real time. If the air in state ② does not reach the required temperature, the electric heating unit 5 starts to work and further heats the air in state ② to state ③. If the air in state ② reaches the required temperature, the electric heating unit 5 does not work and the air passes directly. The inlet of the first three-way valve 6 is connected to the electric heating unit 5 through a conduit, and the outlet is connected to the thermochemical reactor 101 and the third three-way valve 103 through a conduit. At this time, the outlet to the thermochemical reactor 101 is opened, and the hot air in state ③ is heated by the thermochemical reactor 101, and the liquid components contained in the thermochemical energy storage material are removed, and the temperature is cooled and humidified to state ④. The air in state ④ is cooled to state ⑤ after passing through the first heat exchanger 4, and then enters the humidifier 100.

[0044] After the thermochemical reactor 101 is fully charged, it can provide heating or cooling for the carriage 115 and the battery pack 118 of the logistics transport vehicle, and can provide cooling for the motor 120 and the voltage conversion system 122.

The inlet of the second three-way valve 102 is connected to the thermochemical reactor 101 through a conduit, and the outlet is connected to the inlet of the third three-way valve 103 and the fifth three-way valve 105 through a conduit. If there is a demand for heating in the carriage 115 and / or the battery pack 118 of the logistics transport vehicle, the outlet of the second three-way valve 102 leading to the third three-way valve 103 is opened, and the outlet of the third three-way valve 103 is opened. In order to heat the carriage 115 of the logistics transport vehicle, the outlet of the fourth three-way valve 104 to the seventh three-way valve 112 is opened, the outlet of the seventh three-way valve 112 to the carriage cooling / heating device 113 is opened, and the fan 114 starts to work, and the air in state ⑦ heats the carriage 115 of the logistics transport vehicle through the carriage cooling / heating device 113.

After the dry air in state ⑧ passes through the first-stage spray device 109, it is sprayed and cooled to state ⑨. In order to provide cooling for the battery pack 118, the outlet of the five-way valve 110 leading to the sixth three-way valve 111 is opened. At this time, the outlet of the sixth three-way valve 111 leading to the heating plate 117 is opened, and the air in state ⑨ passes through the heating plate 117 to provide cooling for the battery pack 118.

If the carriage 115 and / or the battery pack 118 of the logistics transport vehicle have a heating demand, when the air in state ③ reaches the first three-way valve 6, the outlet of the first three-way valve 6 leading to the third three-way valve 103 is opened, and then the heating steps are the same as after the charging is completed. If the carriage 115 and / or the battery pack 118 and / or the motor 120 and / or the voltage conversion system 122 of the logistics transport vehicle have a cooling demand, when the air in state ① reaches the four-way valve 3, the outlet of the four-way valve 3 leading to the eighth three-way valve 116 is opened, and the outlet of the eighth three-way valve 116 leading to the fifth three-way valve 105 is opened, and then the cooling steps are the same as after the charging is completed.
