The waste heat utilization branch can facilitate the transfer of the waste heat generated by the vehicle to other components, thereby realizing the recovery and utilization of the waste heat generated by the vehicle. The first heat exchange pipe 211 can facilitate the heat exchange of the heat transfer medium, and the first water pump 11 can drive the heat transfer medium to circulate in the flow path to facilitate the heat transfer medium to complete the heat exchange process in the flow path.

[0034] The energy storage branch and the waste heat utilization branch are connected in parallel. The energy storage branch is connected in series with the total heat exchange path and the waste heat utilization branch is connected in series with the total heat exchange path. The energy storage branch includes an energy storage device 12, and the waste heat utilization branch includes an engine waste heat utilization device 13. The waste heat utilization branch includes an engine waste heat utilization device 13, which can collect the waste heat generated during the operation of the engine. And the waste heat utilization branch is connected in series with the total heat exchange path, so that the waste heat generated during the operation of the engine collected by the engine waste heat utilization device 13 can be transmitted to the total heat exchange path, which can improve the recovery rate of the heat generated by the vehicle; moreover, the energy storage branch includes an energy storage device 12, and the energy storage device 12 can store heat.

[0035] The energy storage branch is connected in parallel with the waste heat utilization branch, and the energy storage branch is connected in series with the total heat exchange path, and the waste heat utilization branch is connected in series with the total heat exchange path, which is convenient for distributing and managing the waste heat generated by the vehicle according to actual needs, can improve the recovery rate of the total vehicle heat, reduce energy waste, and is also beneficial to improving the stability and reliability of vehicle operation.

[0036] For example, when the waste heat generated by the vehicle is relatively sufficient, the heat collected by the engine waste heat utilization device 13 in the waste heat utilization branch can be transmitted to the total heat exchange path, and at least a part of the waste heat in the total heat exchange path can be transmitted into the energy storage device 12 of the energy storage branch to realize the storage of heat, which is beneficial to improving the recovery rate of the vehicle waste heat.

[0037] For another example, when the waste heat generated by the vehicle is relatively less, the waste heat generated by the engine collected in the waste heat utilization branch can be transmitted into the total heat exchange path, and the total heat exchange path directly transmits the heat in the waste heat utilization branch into the first heat exchange pipe 211 to meet the heat demand of the absorption refrigeration system, improving the recovery rate of the vehicle waste heat. It can also transmit the heat stored in the energy storage device 12 of the energy storage branch to the total heat exchange path, and the total heat exchange path transmits the heat into the first heat exchange pipe 211 to meet the heat demand of the vehicle, improving the reliability and stability of vehicle operation.

The waste heat in the waste heat utilization energy storage system can be transferred into the first heat exchange tube 211, and the heat exchange process is completed in the first heat exchange tube 211. The waste heat in the first heat exchange tube 211 can heat the absorption refrigeration working medium in the generator unit 2 to separate the absorption refrigeration working medium, facilitating the absorption refrigeration working medium to complete the subsequent heat exchange process. By supplying the waste heat in the waste heat utilization energy storage system to the generator unit 2 through the first heat exchange tube 211, the waste heat generated by the engine can be fully utilized, providing the required heat for the absorption refrigeration system, improving the recovery rate of vehicle waste heat, and reducing energy waste.

[0039] By adopting the absorption refrigeration system to cool or heat the interior of the vehicle, it is beneficial to reduce energy consumption and can also reduce noise.

[0040] The condenser unit 3 is connected between the generator unit 2 and the throttling unit 18, and the throttling unit 18 is connected between the condenser unit 3 and the evaporator unit 4. The condenser unit 3 can facilitate heat exchange with the absorption refrigeration working medium in the generator unit 2 to absorb the heat in the absorption refrigeration working medium, thereby achieving rapid cooling of the absorption refrigeration working medium. The throttling unit 18 can throttle and depressurize the absorption refrigeration working medium flowing out of the condenser unit 3, and the evaporator unit 4 can facilitate heat exchange with the absorption refrigeration working medium flowing out of the throttling unit 18 to provide heat to the absorption refrigeration working medium, thereby achieving rapid heating of the absorption refrigeration working medium.

[0041] The absorber unit 17 has a first absorber inlet 171, a second absorber inlet 172, and an absorber outlet 173. The evaporator unit 4 is connected to the first absorber inlet 171, the second absorber inlet 172 is connected to the generator unit 2, and the solution pump 14 is connected between the absorber outlet 173 and the generator unit 2. The absorber unit 17 can recover the absorption refrigeration working medium that has completed heat exchange in the evaporator unit 4 and can also collect the remaining absorption refrigeration working medium in the generator unit 2. The first absorber inlet 171 can facilitate the absorption refrigeration working medium in the evaporator unit 4 to flow into the absorber unit 17, and the second absorber inlet 172 can facilitate the remaining absorption refrigeration working medium in the generator unit 2 to flow into the absorber unit 17. The solution pump 14 is connected between the absorber outlet 173 and the generator unit 2 to drive the collected absorption refrigeration working medium in the absorber unit 17 to flow back into the generator unit 2, completing the recycling of the absorption refrigeration working medium.

[0042] For example, the circulation process of the absorption refrigeration working fluid in the flow path can be as follows: The absorption refrigeration working fluid exchanges heat with the heat exchange working fluid in the first heat exchange tube 211 in the generator unit 2. The absorption refrigeration working fluid can absorb the heat in the first heat exchange tube 211. At least a part of the absorption refrigeration working fluid flows to the condenser unit 3 after absorbing heat for subsequent heat exchange. The remaining absorption refrigeration working fluid in the generator unit 2 flows into the absorber unit 17 through the second absorber inlet 172. The absorption refrigeration working fluid flows into the condenser unit 3 and exchanges heat with the heat exchange working fluid in the condenser unit 3. The absorption refrigeration working fluid after heat exchange in the condenser unit 3 flows to the throttling unit 18. The throttling unit 18 can throttle and depressurize the absorption refrigeration working fluid after heat exchange in the condenser unit 3, and then flows into the evaporator unit 4. The absorption refrigeration working fluid exchanges heat in the evaporator unit 4 and then flows into the absorber unit 17 through the first absorber inlet 171. The solution pump 14 can drive the absorption refrigeration working fluid in the absorber unit 17 to flow into the generator unit 2 to complete the recycling process of the absorption refrigeration working fluid in the absorber unit 17.

[0043] The condensation circulation system includes a condensation heat exchanger 31, a heat dissipation component, and a second water pump 32. The condensation heat exchanger 31, the heat dissipation component, and the second water pump 32 are connected in series to form a condensation circulation flow path. The condensation heat exchanger 31 is located in the condenser unit 3 to absorb the heat generated by the condenser unit 3. The condensation heat exchanger 31 can absorb the heat generated by the condenser unit 3. The absorption refrigeration working fluid flows into the condenser unit 3 and exchanges heat with the condensation heat exchanger 31. The condensation heat exchanger 31 can absorb the heat of the absorption refrigeration working fluid in the condenser unit 3 to quickly cool the absorption refrigeration working fluid. The heat dissipation component can quickly dissipate the heat absorbed in the condensation heat exchanger 31 to prevent the temperature of the condenser unit 3 from being too high and affecting the reliability and stability of the condenser unit 3.

[0044] For example, the condensation heat exchanger 31 is provided with a heat exchange working fluid. The heat exchange working fluid exchanges heat with the absorption refrigeration working fluid in the condenser unit 3 to cool the absorption refrigeration working fluid. The heat exchange working fluid in the condensation heat exchanger 31 can absorb the heat in the absorption refrigeration working fluid to quickly cool the absorption refrigeration working fluid. The second water pump 32 can drive the heat exchange working fluid to circulate in the condensation circulation flow path so that the heat exchange working fluid completes the heat exchange process in the condensation circulation system.

[0045] The evaporation cycle system includes an evaporation heat exchanger 41, an air-conditioning refrigeration heat exchange core 42, and a third water pump 43. The evaporation heat exchanger 41, the air-conditioning box heat exchange core, and the third water pump 43 are connected in series to form an evaporation cycle flow path. The evaporation heat exchanger 41 is located in the evaporator unit 4 and is used to provide heat to the evaporator unit 4. The evaporation heat exchanger 41 can provide heat to the evaporator unit 4, absorb the refrigerant flowing into the evaporator unit 4, and exchange heat with the evaporation heat exchanger 41. The evaporation heat exchanger 41 can provide heat to the refrigerant absorbed in the evaporator unit 4 to rapidly increase the temperature of the absorbed refrigerant.

[0046] For example, a heat exchange refrigerant is provided in the evaporation heat exchanger 41. The heat exchange refrigerant exchanges heat with the absorbed refrigerant in the evaporator unit 4. The absorbed refrigerant can absorb the heat of the heat exchange refrigerant in the evaporation heat exchanger 41 to rapidly increase the temperature of the absorbed refrigerant. The third water pump 43 can drive the heat exchange refrigerant to circulate in the evaporation cycle flow path so that the heat exchange refrigerant completes the heat exchange process in the evaporation condensation cycle system.

[0047] For example, the absorbed refrigerant used in the absorption refrigeration system is an aqueous solution of lithium bromide.

[0048] For example, the heat exchange refrigerant used in at least one of the waste heat utilization energy storage system, the condensation cycle system, and the evaporation cycle system is an aqueous solution of ethylene glycol.

[0049] Among them, the thermal management system has a waste heat energy storage mode and a waste heat utilization mode. In the waste heat energy storage mode, the solution pump 14 is closed. In the waste heat utilization mode, the solution pump 14 is turned on. In the waste heat energy storage mode, the closing of the solution pump 14 enables the heat in the heat exchange main path to directly flow into the energy storage device 12 in the energy storage branch, so as to realize the storage function of the waste heat collected by the waste heat utilization branch of the vehicle, facilitate the subsequent ready use of the heat, and improve the recovery and utilization rate of the vehicle waste heat. In the waste heat utilization mode, the opening of the solution pump 14 can make the heat in the waste heat utilization branch flow into the first heat exchange tube 211 in the heat exchange main path, so that the first heat exchange tube 211 provides heat for the absorbed refrigerant in the generator unit 2, so as to make full use of the waste heat generated by the engine collected in the engine waste heat utilization device 13, realize the process of providing heat for the absorption refrigeration system, and facilitate the subsequent heat exchange of the absorption refrigeration system.

[0050] The thermal management system has a waste heat energy storage mode and a waste heat utilization mode, and the on / off control of the solution pump 14 switches between the waste heat energy storage mode and the waste heat utilization mode. By using the waste heat generated by the engine collected in the waste heat utilization branch to provide heat for the absorption refrigeration system, the waste heat recovery and utilization rate of the vehicle can be improved. Moreover, through the waste heat energy storage mode, the storage function of the vehicle's waste heat can be realized, facilitating the subsequent ready access to the heat. For example, when the waste heat of the vehicle is relatively small, the waste heat energy storage mode in series with the total heat exchange circuit can transfer the heat stored in the waste heat energy storage mode to the first heat exchange tube 211 in the total heat exchange circuit to meet the heat required by the absorption refrigeration system, which can further improve the waste heat recovery and utilization rate of the vehicle and reduce energy waste.

The waste heat utilization mode can use the collected waste heat of the vehicle to provide heat for the absorption refrigeration system, improving the waste heat recovery and utilization rate of the vehicle. Moreover, the waste heat energy storage mode can store the waste heat of the vehicle for subsequent ready access, which can further improve the waste heat recovery and utilization rate of the vehicle. For example, when the waste heat of the vehicle is relatively small, the waste heat energy storage mode in series with the total heat exchange circuit can transfer the heat stored in the energy storage device 12 to the first heat exchange tube 211 in the total heat exchange circuit to meet the heat required by the absorption refrigeration system.

The cooling flow path can facilitate the cooling of the radiator 33 to quickly reduce the temperature of the radiator 33 and prevent the radiator 33 from being affected by too high a temperature and affecting its reliability.

[0057] One end of the cooling flow path is connected between one end of the evaporator unit 4 and one end of the air-conditioning refrigeration heat exchange core 42, and the other end of the cooling flow path is connected between the other end of the evaporator unit 4 and the other end of the air-conditioning refrigeration heat exchange core 42, which can transfer the heat in the radiator 33 into the evaporator unit 4. While cooling the radiator 33, it can provide heat for the evaporation heat exchanger 41 in the evaporator unit 4. When the refrigerant flows into the evaporator unit 4, it can absorb the heat in the evaporator unit 4, thereby realizing the rapid cooling of the heat exchange working medium in the evaporation heat exchange tube. The heat exchange working medium after heat exchange in the evaporator unit 4 can flow to the air-conditioning refrigeration heat exchange core 42 and perform heat exchange with the air-conditioning refrigeration heat exchange core 42 to realize the cooling of the vehicle interior.

[0058] For example, when the vehicle air conditioner is cooling, the absorption refrigeration working fluid in the generator unit 2 flows to the condenser unit 3. After heat exchange with the heat exchange working fluid in the condensation heat exchanger 31, the absorption refrigeration working fluid flows into the evaporator unit 4. The heat exchange working fluid in the condensation heat exchanger 31 flows to the radiator 33. The heat in the radiator 33 can be transferred to the evaporator unit 4 through the cooling flow path. The absorption refrigeration working fluid flowing into the evaporator unit 4 can absorb the heat in the evaporator unit 4, so that the heat exchange working fluid in the evaporation heat exchange tube can be quickly cooled. The heat exchange working fluid after heat exchange in the evaporator unit 4 can flow to the air-conditioning cooling heat exchange core 42 and exchange heat with the air-conditioning cooling heat exchange core 42 to achieve the cooling of the vehicle interior. The heat exchange working fluid that exchanges heat with the evaporation heat exchange tube can flow into the absorber unit 17, and the heat exchange working fluid that exchanges heat with the air-conditioning cooling heat exchange core 42 flows back into the evaporation heat exchange tube and continues to circulate to reach the required cooling capacity inside the vehicle.

[0059] A second control valve 35 is connected to the cooling flow path, and the second control valve 35 is used to control the on-off of the cooling flow path. Controlling the on-off of the cooling flow path by the second control valve 35 can facilitate the heat management system to control whether the heat in the radiator 33 flows to the evaporator unit 4 to provide heat to the evaporator unit 4 under different conditions.

[0060] Among them, at least part of the cooling flow path being thermally connected or in thermal contact with the radiator 33 may include the following situations: For example, a part of the cooling flow path may be thermally connected or in thermal contact with the radiator 33; for another example, the entire cooling flow path may be thermally connected or in thermal contact with the radiator 33.

[0061] Refer to Figure 1 and Figure 2 , according to some embodiments of the present invention, the heat dissipation assembly includes an air-conditioning heating heat exchange core 34. The condensation heat exchanger 31, the air-conditioning heating heat exchange core 34 and the second water pump 32 are connected in series to form a second condensation circulation flow path. The condensation circulation system further includes a third control valve 44. The third control valve 44 is used to control the on-off of the second condensation circulation flow path, and can transfer the heat in the condensation heat exchanger 31 to the air-conditioning heating heat exchange core 34 to exchange heat with the air-conditioning heating heat exchange core 34 to achieve the heating of the vehicle interior. Controlling the on-off of the second condensation circulation flow path by the third control valve 44 can facilitate the heat management system to control whether the heat in the heat exchange working fluid flowing out of the condensation heat exchanger 31 flows to the air-conditioning heating heat exchange core 34 for heat dissipation under different conditions.

[0062] For example, when the vehicle air conditioner is heating, the absorption refrigeration working fluid in the generator unit 2 flows to the condenser unit 3, exchanges heat with the heat exchange working fluid in the condensation heat exchanger 31, then the absorption refrigeration working fluid flows into the evaporator unit 4, and the heat exchange working fluid in the condensation heat exchanger 31 flows to the vehicle heating heat exchange core 34, exchanges heat with the vehicle heating heat exchange core 34 to raise the temperature inside the vehicle. The heat exchange working fluid flows back into the condensation heat exchanger 31 and continues to circulate to achieve the required heating capacity inside the vehicle. The absorption refrigeration working fluid after exchanging heat with the condensation heat exchanger 31 can flow into the evaporator unit 4, and the absorption refrigeration working fluid flowing into the evaporator unit 4 can flow into the absorber unit 17.

[0063] Referring to Figures 3-5 , according to some embodiments of the present invention, a fourth control valve 16 for controlling the on / off of the waste heat utilization branch is provided on the waste heat utilization branch, and the thermal management system has an energy storage and reuse mode. The fourth control valve 16 controls the on / off of the waste heat utilization branch, which can facilitate the thermal management system to control whether the heat in the heat exchange working fluid flowing out of the waste heat utilization branch flows to the energy storage branch for storage under different conditions.

[0064] Among them, in the waste heat energy storage mode and the waste heat utilization mode, the fourth control valve 16 is opened, which can transfer at least a part of the waste heat in the vehicle preheating collected by the waste heat utilization branch to the absorption refrigeration system, provide the required heat for the absorption refrigeration system, enable the absorption refrigeration system to quickly reach the required refrigeration / heating effect, and improve the recovery and utilization rate of the vehicle waste heat; it can also transfer at least a part of the vehicle waste heat collected by the waste heat utilization branch to the energy storage branch to realize the function of storing the vehicle waste heat, facilitating the subsequent ready use of heat, and further improving the recovery and utilization rate of the vehicle waste heat.

[0065] For example, when the heat demand of the absorption refrigeration system is relatively small or the waste heat generated by the vehicle is relatively sufficient, the fourth control valve 16 can be controlled to open, so that a part of the waste heat in the waste heat utilization branch is transferred to the absorption refrigeration system, enabling the absorption refrigeration system to reach the required refrigeration / heating effect, and at the same time, a part of the waste heat in the waste heat utilization branch can be transferred to the energy storage device 12 in the energy storage branch to realize the function of storing the vehicle waste heat.

[0066] In the energy storage and reuse mode, the fourth control valve 16 is closed and the solution pump 14 is opened, which can transfer the waste heat stored in the energy storage branch to the absorption refrigeration system to provide heat for the absorption refrigeration system and improve the utilization rate of the vehicle waste heat.

[0067] For example, when the waste heat generated by the vehicle is relatively small or the heat demand of the absorption refrigeration system is relatively large, the fourth control valve 16 can be controlled to close, so that the heat stored in the energy storage branch provides heat for the absorption refrigeration system at the same time.

[0079] For example, the recycling process of the absorption refrigeration working fluid in the absorption refrigeration system can be as follows: After the absorption refrigeration working fluid exchanges heat with the first heat exchange tube 211 in the high-pressure generator 21, the absorption refrigeration working fluid is separated into a gaseous absorption refrigeration working fluid and a liquid absorption refrigeration working fluid under certain conditions. The gaseous absorption refrigeration working fluid flows into the second heat exchange tube 221 of the first-stage medium-pressure generator 22 through the first steam outlet 212 and the inlet of the second heat exchange tube 221, and then the gaseous absorption refrigeration working fluid flows into the condenser unit 3 through the outlet of the second heat exchange tube 221 and the condenser inlet 36. After heat exchange in the condenser unit 3, the absorption refrigeration working fluid flows towards the throttling unit 18 through the condenser outlet 37, and then the absorption refrigeration working fluid flows into the evaporator unit 4 through the evaporator inlet 45.

The gaseous absorption refrigeration working fluid separated in the first-stage medium-pressure generator 22 can flow into the second-stage medium-pressure generator 23 through the second steam outlet 222 and the inlet of the third heat exchange tube 231. After heat exchange in the second-stage medium-pressure generator 23, it flows into the condenser unit 3 through the outlet of the third heat exchange tube 231 and the condenser inlet 36. The liquid absorption refrigeration working fluid in the first-stage medium-pressure heat exchanger can flow into the second-stage medium-pressure generator 23 through the second concentrated solution outlet 223 for further separation. The gaseous absorption refrigeration working fluid separated in the second-stage medium-pressure generator 23 can flow into the condenser unit 3 through the third steam outlet 232 and the condenser inlet 36.

[0082] Refer to Figure 1 and Figure 2, according to some embodiments of the present utility model, a fifth control valve 174 is connected between the third concentrated solution outlet 233 and the second absorber inlet 172. The fifth control valve 174 is used to control the on-off between the third concentrated solution outlet 233 and the second absorber inlet 172.

The fifth control valve 174 controls the on-off between the third concentrated solution outlet 233 and the second absorber inlet 172, which can facilitate the heat management system to control whether the heat in the heat exchange working medium flowing out of the secondary medium-pressure generator 23 flows into the absorber unit 17 for recovery under different conditions.

The fourth heat exchange flow path is connected between the solution pump 14 and the second heat exchange flow path. The second heat exchange flow path is connected between the fourth heat exchange flow path and the solution recovery port 214.

[0084] When the liquid absorption refrigeration working medium flowing out of the first concentrated solution outlet 213 of the high-pressure generator 21 flows through the first solution heat exchanger 19 to the first intermediate solution inlet 224 of the primary medium-pressure generator 22, heat exchange can be carried out in the first heat exchange flow path so that the first solution heat exchanger 19 absorbs the heat in the liquid absorption refrigeration working medium and stores it, which can improve the utilization rate of the waste heat in the absorption refrigeration working medium and thus is beneficial to the efficient operation of the vehicle.

[0085] When the absorption refrigeration working medium flows through the second heat exchange flow path to the solution recovery port 214, since the first heat exchange flow path and the second heat exchange flow path can exchange heat with each other, the heat absorbed and stored by the first heat exchange flow path can be transferred into the second heat exchange flow path to preheat the absorption refrigeration working medium in the second heat exchange flow path, which is beneficial to improving the reaction efficiency of the absorption refrigeration working medium in the high-pressure generator 21 subsequently.

[0086] When the liquid absorption refrigeration working medium flowing out of the third concentrated solution outlet 233 of the secondary medium-pressure generator 23 flows through the second solution heat exchanger 20 towards the second absorber inlet 172 of the absorber unit 17, heat exchange can be carried out in the third heat exchange flow path so that the second solution heat exchanger 20 absorbs the heat in the liquid absorption refrigeration working medium and stores it, which can improve the utilization rate of the waste heat in the absorption refrigeration working medium, thus being beneficial to the efficient operation of the vehicle.

[0087] When the absorption refrigeration working medium flows from the absorber outlet 173 to the second heat exchange flow path through the fourth heat exchange flow path, since the third heat exchange flow path and the fourth heat exchange flow path can exchange heat with each other, the heat absorbed and stored in the third heat exchange flow path can be transferred to the fourth heat exchange flow path to preheat the absorption refrigeration working medium in the fourth heat exchange flow path, which is beneficial to improving the reaction efficiency of the absorption refrigeration working medium in the high-pressure generator 21 subsequently.

[0088] By providing the absorption refrigeration system with the first solution heat exchanger 19 and the second solution heat exchanger 20, the absorption refrigeration working medium can carry out heat exchange in the first solution heat exchanger 19 and the second solution heat exchanger 20 during the circulation process, which can improve the utilization rate of the waste heat in the absorption refrigeration working medium and can also improve the reaction efficiency of the absorption refrigeration working medium in the high-pressure generator 21, being beneficial to the efficient operation of the vehicle.

For example, when the waste heat of the vehicle is relatively small, the waste heat energy storage mode and the heat exchange main path are connected in series, and the heat stored in the energy storage device 12 can be transferred into the first heat exchange tube 211 in the heat exchange main path to meet the heat required by the absorption refrigeration system.
