Detailed Description

Specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.

In this disclosure, unless otherwise indicated, terms of orientation such as "inner and outer" are used herein to define the outline of the corresponding component. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated.

According to a first aspect of the disclosed embodiments, a thermal management system is provided, referring to fig. 1, comprising a heat exchange module 10 for exchanging heat, such as may be used for exchanging heat with a passenger compartment, the thermal management system further comprising an engine module 20 flowing through the engine and a tail module 30 flowing through a tail unit of the vehicle, wherein the engine module 20 is selectively in communication with the heat exchange module 10 to form a first circuit, and the tail module 30 is selectively in communication with the heat exchange module 10 to form a second circuit. The heat exchange module 10 may be a heat exchanger, the engine module 20 may be a water jacket circulating inside the engine, the liquid in the water jacket may absorb heat generated by the engine during operation, the tail exhaust module 30 may be a pipeline formed on the tail exhaust device, and the liquid in the pipeline may absorb heat of gas exhausted by the engine. In addition, the first circuit communicating with the engine module 20 and the second circuit communicating with the tail module 30 are independent and do not affect each other, so that they can heat the passenger compartment separately or simultaneously.

Through the above technical scheme, the heat exchange module 10 can be communicated with the engine module 20 and the tail exhaust module 30, when the vehicle is cold started in winter and the temperature of cooling liquid in the engine cannot be raised for a long time so as to quickly raise the temperature in the passenger cabin, the tail exhaust module 30 can be communicated with the heat exchange module 10 to heat the passenger cabin, and the exhaust temperature of the engine can be very high when the engine is started, so that the heating requirement of the passenger cabin can be quickly raised through the tail exhaust module 30, and particularly, the comfort level of passengers in the vehicle can be quickly improved in winter. And, the passenger compartment is heated by the tail exhaust module 30 without using the engine coolant, so that the normal warm-up of the engine is not affected, and the engine can be warmed up quickly. In addition, the exhaust gas exhausted by the engine heats the passenger cabin, so that the heat of the exhaust gas can be effectively recovered, the waste of the heat is avoided, and the heat damage of the exhaust gas to the vehicle is also avoided.

The tail assembly may include various components ranging from an exhaust port of the engine to an exhaust pipe end of the vehicle, and the tail module 30 may be disposed on any of the components. For example, the tail block 30 may be configured to flow through the interior of a muffler having a catalyst integrated therein. The tail exhaust module 30 is arranged in the muffler integrated with the catalyst, can be close to the exhaust distance of the engine, has small exhaust temperature loss, and can heat the cooling liquid by utilizing the exhaust temperature to the maximum extent so as to quickly raise the temperature in the vehicle. And the catalyst in the catalyst also generates heat after reaction, so that a certain amount of heat can be provided for the coolant in the tail block 30. This location of the tail boom module 30 in the disclosed embodiments may rapidly raise the temperature within the passenger compartment and pertains to exhaust gas recovery, saving energy consumption for heating.

Referring to fig. 1, in an embodiment of the present disclosure, the thermal management system may include a PTC module 40, the PTC module 40 being selectively in communication with the heat exchange module 10 to form a third circuit. When the engine module 20 or the tail row module 30 or both are used for heating the passenger cabin, but the passenger cabin temperature requirement cannot be met quickly, or when the engine module 20 or the tail row module 30 cannot be used for heating the passenger cabin, the PTC module 40 can be used for heating the passenger cabin, so that the passenger cabin heating requirement can be met quickly.

Referring to fig. 1, in an embodiment of the present disclosure, the thermal management system may include a valve assembly 50 disposed upstream of the heat exchange module 10, the valve assembly 50 being configured to enable selective communication of the PTC module 40, the tail row module 30, and the engine module 20, respectively, with the heat exchange module 10. By providing the valve assembly 50, the modules can be used independently or partially simultaneously or all at the same time, so that the heating requirement of the passenger cabin can be met rapidly under various conditions, and the comfort of passengers is ensured.

The valve assembly 50 may include a plurality of valves or may be an integrated valve. For example, in one embodiment, the valve assembly 50 may include a six-way valve, a first inlet of which may be connected to an outlet of the engine module 20, a first outlet of which is in communication with the first inlet, and connected to an inlet of the heat exchange module 10, such that the engine module 20 may be in communication with the heat exchange module 10; a second inlet of the six-way valve may be connected to an outlet of the tail block module 30, and a third inlet may be connected to an outlet of the PTC module 40, and a second outlet of the six-way valve may be in communication with the second inlet and the third inlet and connected to an inlet of the heat exchange module 10, so that the PTC module 40 and the tail block module 30 may be in communication with the heat exchange module 10. Wherein the third outlet of the six-way valve may be in communication with the first inlet and connected to the inlet of the engine module 20, and when the temperature of the coolant in the engine is low and the passenger compartment cannot be heated, the engine module may be caused to self-circulate the engine coolant through the first inlet and the third outlet of the six-way valve without being introduced into the heat exchange module 10 to participate in the heating of the passenger compartment. The six-way valve is adapted to shorten the path of each flow path to rapidly raise the temperature in the vehicle in a minimum time. In other embodiments, the valve assembly 50 may be a five-way valve with an on-off flow passage disposed therein, and the internal flow passage of the five-way valve may allow the outlet of the engine module 20 to communicate with the heat exchange module 10 or with the inlet of the engine module 20 to perform self-circulation warming.

In the presently disclosed embodiment, referring to fig. 1, the thermal management system may include a first three-way valve 60, with an inlet of the first three-way valve 60 in communication with an outlet of the heat exchange module 10, one outlet of the first three-way valve 60 for an inlet to the engine module 20 and another outlet for an inlet to the PTC module 40. The inlet of the first three-way valve 60 and the outlet communicated with the engine module 20 are normally open, and whether the PTC module is connected into the loop to participate in heating the passenger cabin can be controlled by opening and closing the outlet of the first three-way valve 60 communicated with the PTC module 40.

According to one embodiment of the present disclosure, referring to fig. 1, the thermal management system may include a shut-off valve 70, the shut-off valve 70 being releasably connected between an outlet of the heat exchange module 10 and an inlet of the heel row module 30. The shut-off valve 70 may control, on the one hand, whether the tail block 30 is connected to the circuit to participate in the heating of the passenger compartment, and, on the other hand, when the tail block 30 is not used for heating, the shut-off valve 70 may be closed first so that the coolant no longer enters the tail block 30, and when the coolant completely flows out of the tail block, the valve downstream of the tail block 30 may be closed again. The stop valve 70 can enable the cooling liquid to completely flow out of the tail-row module 30, so that repeated dry burning of the cooling liquid in the tail-row module 30 is avoided.

The thermal management system may include an engine cooling system, referring to fig. 1, including a radiator 80, with an outlet of the engine module 20 selectively coupled to an inlet of the radiator 80, and an outlet of the radiator 80 coupled to an inlet of the engine module 20. In the engine warm-up phase, the coolant flowing out of the engine module 20 may be directly returned to the engine module 20 without passing through the radiator 80, and when the engine needs to be cooled, the coolant flowing out of the engine module 20 is cooled by the radiator 80 and then returned to the engine module 20.

In an embodiment of the disclosure, to facilitate selective connection of the flow paths according to different operating conditions, the thermal management system may further include a second three-way valve 90, an inlet of the second three-way valve 90 is connected to an outlet of the engine module 20, one outlet of the second three-way valve 90 is connected to an inlet of the engine module 20, and another outlet is connected to an inlet of the radiator 80. At the time of warm-up, the outlet of the second three-way valve 90 connected to the radiator 80 is closed; when the engine needs to be cooled, the outlet of the second three-way valve 90, which is connected to the engine module 20, is closed.

In the embodiment of the disclosure, the air conditioner control unit may be configured to control each valve, so as to control on-off conditions of the valves according to different working conditions, so that the thermal management system has multiple working states, where the air conditioner control unit 100 may be connected with an electronic control unit of a vehicle. Shown in phantom in fig. 1 is an electronically controlled connection diagram of the various components of the air conditioning control unit 100.

Flow path conditions under various conditions in the embodiments of the present disclosure are described below in connection with the flow path diagrams shown in fig. 2 to 6.

Referring to FIG. 2, an engine warm-up, tail row module 30 is shown heating the passenger compartment. When the engine is cold started or the temperature of cooling liquid in the engine is lower than a preset temperature value (such as 70 ℃), the battery is fed (namely, the battery power is insufficient), and the air conditioner is started for heating, the flow path of the cooling liquid is two paths, and one path is an engine warming loop: the coolant flows out of the water pump assembly and sequentially into the engine module 20, the valve assembly 50, the first three-way valve 60, the second three-way valve 90, and finally back into the engine module; the other path is a heating loop of the tail row module 30 for the passenger cabin: after flowing out of the heat exchange module 10, the cooling liquid sequentially passes through the first three-way valve 60, the stop valve 70, the tail row module 30 and the valve assembly 50, and finally returns to the heat exchange module 10.

Referring to fig. 3, an engine warm-up, PTC module 40 is shown heating the passenger compartment. When the engine is cold started or the temperature of cooling liquid in the engine is lower than a preset temperature value (such as 70 ℃), the battery is not fed (namely the battery electric quantity is sufficient), and the air conditioner is started for heating, the flow path of the cooling liquid is two paths, and one path is an engine warming loop: the coolant flows out of the water pump assembly and sequentially into the engine module 20, the valve assembly 50, the first three-way valve 60, the second three-way valve 90, and finally back into the engine module; the other way is for the PTC module 40 to heat the passenger compartment: after flowing out of the heat exchange module 10, the cooling liquid passes through the first three-way valve 60, the PTC module 40, the valve assembly 50 in order, and finally returns to the heat exchange module 10. Under such a working condition, the tail row module 30 can be started to heat the passenger cabin at the same time, but when the engine of the hybrid vehicle is not started, the battery is not fed, and the air conditioner is started to heat, only the PTC module 40 can be controlled to heat the passenger cabin.

Referring to fig. 4, an engine warm-up, tail row module 30 and PTC module 40 are shown heating the passenger compartment. When the engine is cold started or the temperature of cooling liquid in the engine is lower than a preset temperature value (such as 70 ℃), the battery is not fed (namely the battery is sufficient in electric quantity), and the air conditioner is started for heating, the flow path of the cooling liquid is three paths, and one path is an engine warming loop: the coolant flows out of the water pump assembly and sequentially into the engine module 20, the valve assembly 50, the first three-way valve 60, the second three-way valve 90, and finally back into the engine module; the other way is for the PTC module 40 to heat the passenger compartment: after flowing out of the heat exchange module 10, the cooling liquid sequentially passes through the first three-way valve 60, the PTC module 40 and the valve assembly 50, and finally returns to the heat exchange module 10; also, the tail row module 30 heats the loop for the passenger cabin: after flowing out of the heat exchange module 10, the cooling liquid sequentially passes through the first three-way valve 60, the stop valve 70, the tail row module 30 and the valve assembly 50, and finally returns to the heat exchange module 10. When the temperature of the cooling fluid in the engine is higher than the preset temperature (e.g. 85 ℃), the second three-way valve 90 is connected to the radiator 80, and the outlet of the second three-way valve 90 connected to the inlet of the engine module 20 is disconnected, so that the cooling fluid flowing out of the engine is cooled by heat dissipation through the radiator 80.

Referring to fig. 5, the engine module 20 heats the passenger compartment, and when the coolant in the engine is higher than a preset temperature (e.g., 90 ℃) and the air conditioner is turned on for heating, the coolant flow path is the engine module 20 heats the passenger compartment: the coolant flows out of the water pump assembly and into the engine module 20, the valve assembly 50, the heat exchange module 10, the first three-way valve 60, the second three-way valve 90, the radiator 80 in that order, and finally back to the engine module 20.

Referring to fig. 6, the engine module 20, the tail row module 30, and the PTC module 40 are shown together heating the passenger compartment. When the temperature of cooling liquid in the engine is lower than a preset temperature (such as 70 ℃), the air conditioner is started to heat and the heating demand temperature is above 32 ℃, the cooling liquid flows through three paths because of the large heating demand, and the cooling liquid heats the passenger cabin in one path: the engine module 20 heats the passenger compartment: the coolant flows out of the water pump assembly and flows into the engine module 20, the valve assembly 50, the heat exchange module 10, the first three-way valve 60, the second three-way valve 90, the radiator 80 in sequence, and finally returns to the engine module 20; the other way is for the PTC module 40 to heat the passenger compartment: after flowing out of the heat exchange module 10, the cooling liquid sequentially passes through the first three-way valve 60, the PTC module 40 and the valve assembly 50, and finally returns to the heat exchange module 10; also, the tail row module 30 heats the loop for the passenger cabin: after flowing out of the heat exchange module 10, the cooling liquid sequentially passes through the first three-way valve 60, the stop valve 70, the tail row module 30 and the valve assembly 50, and finally returns to the heat exchange module 10. Wherein the passenger compartment may be heated by one or more of the engine module 20, the tail row module 30, and the PTC module 40 when the passenger compartment heating demand is below 32 ℃.
