Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The thermal management system 100 of the vehicle of the present invention, which includes a heat pump cycle system, is described below in conjunction with fig. 1-5. The vehicle may be a construction machine powered by a battery, that is, the vehicle has a power battery 119, and the power battery 119 is a power source of the vehicle, and drives the vehicle to travel or perform an action. Here, the vehicle may be an electric heavy truck, an electric excavator, or an electric mixer.
Specifically, referring to fig. 1, the heat pump cycle system includes a compressor 110, a valve switching group 111, a first heat exchanger 112, a second heat exchanger 113, and a third heat exchanger 114, and the second heat exchanger 113 and the third heat exchanger 114 are used for exchanging heat with the cab. For example, as shown in fig. 1, a fan 118 may be disposed at the second heat exchanger 113 and the third heat exchanger 114, the second heat exchanger 113 and the third heat exchanger 114 exchange heat with the ambient environment, the fan 118 drives the air around the second heat exchanger 113 and the third heat exchanger 114 to move, and the air after heat exchange may flow to the cab, so as to achieve the purpose of heating or cooling the cab. The direction change valve group 111 is used for changing the flow direction of the refrigerant. It should be noted that the reversing valve group 111 may include a plurality of electromagnetic valves, each electromagnetic valve is correspondingly disposed at a pipeline, and the on/off of the electromagnetic valve may control the on/off of the corresponding pipeline, so as to enable the refrigerant to flow along a predetermined pipeline.
In addition, it should be noted that the heat pump cycle system further includes a valve 151, a reservoir 116, and other components, and the valve 151 and the reservoir 116 are connected in series on the refrigerant cycle loop. In addition, the valve body 151 at different positions may be different types of control valves, for example, the valve body 151 may be a solenoid valve, an electronic expansion valve, an electromagnetic expansion valve, a thermostatic expansion valve with a shut-off function, or the like. The selection of the type of the valve 151 and the connection manner of the liquid storage tank 116 are not particularly limited as long as the requirements of the heat pump cycle for refrigerant circulation and cooling and heating can be satisfied.
The vehicle has a cab heating mode and a cab cooling mode. For example, in summer, when the temperature of the cab is too high and refrigeration is needed, the cab refrigeration mode can be started; in winter, when the temperature of the cab is too low and heating is needed, the cab heating mode can be started.
Referring to fig. 2, in the cab heating mode, the refrigerant in the compressor 110 passes through the reversing valve group 111, then flows to the second heat exchanger 113 and the first heat exchanger 112 in sequence, and then returns to the compressor 110, and the second heat exchanger 113 is used for heating the cab. After the refrigerant in the compressor 110 is compressed, the refrigerant flows to the second heat exchanger 113 first and then flows to the first heat exchanger 112 under the control of the reversing valve set 111, the refrigerant condenses at the second heat exchanger 113 to release heat, evaporates and absorbs heat at the first heat exchanger 112, the ambient temperature around the first heat exchanger 112 decreases, and the ambient temperature around the second heat exchanger 113 increases. Under the action of the blower 118, air having a lower temperature is blown toward the outside of the vehicle and diffused into the external environment; the air with higher temperature is blown into the cab, thereby achieving the effect of heating the cab.
Referring to fig. 3, in the cab refrigeration mode, the refrigerant in the compressor 110 flows through the reversing valve group 111, then flows to the first heat exchanger 112 and the third heat exchanger 114 in sequence, and then returns to the compressor 110, and the third heat exchanger 114 is used for refrigerating the cab. It should be noted that after the refrigerant in the compressor 110 is compressed, the refrigerant flows to the first heat exchanger 112 first and then flows to the third heat exchanger 114 under the control of the reversing valve set 111, and the refrigerant is condensed at the first heat exchanger 112 to release heat and is evaporated at the third heat exchanger 114 to absorb heat; the ambient temperature around the first heat exchanger 112 increases and the ambient temperature around the third heat exchanger 114 decreases. Under the action of the blower 118, air having a relatively high temperature is blown to the outside of the vehicle and diffused into the external environment; air with a lower temperature is blown into the cab, thereby achieving the effect of cooling the cab.
In vehicles using a power battery as a power source, it is most common and simple to provide a cooling or heating function for a cab using electric energy. However, the cooling or heating process of the cab needs to consume a large amount of power, so that the dependence degree of the vehicle on the electric power is improved, and the mileage of the vehicle is shortened.
According to the thermal management system 100 of the vehicle, the heat pump circulating system is arranged, and the heat pump circulating system is used for heating and cooling the cab, so that the dependence on the power battery 119 can be reduced, and the mileage of the whole vehicle can be increased.
In addition, in the cab heating mode, the refrigerant is condensed and absorbs heat at the second heat exchanger 113, and the pressure of the refrigerant condensation is borne by the second heat exchanger 113; in the cab cooling mode, the refrigerant evaporates and absorbs heat at the third heat exchanger 114, and the refrigerant evaporation pressure is applied to the third heat exchanger 114. Because the refrigerant generates different degrees of pressure to the heat exchanger in the condensation or evaporation process, the corresponding heat exchanger only bears one pressure in the heating or refrigeration mode by arranging the second heat exchanger 113 and the third heat exchanger 114, so that the requirement of the heat exchanger on the bearing pressure can be reduced, and the stability and the reliability of the heat exchanger can be improved.
It is considered that the power battery 119 continues to operate while the vehicle is running, resulting in an increase in the temperature of the power battery 119. And the vehicle is provided with a battery cooling mode, so that the power battery 119 can be cooled and radiated.
According to some embodiments of the present invention, in conjunction with fig. 1 and 4, thermal management system 100 further includes a first cyclical heat exchange system 120 and a battery cooler 150. The first circulation heat exchange system 120 exchanges heat with the power battery 119 and the battery cooler 150. Here, the battery cooler 150 may be a plate heat exchanger.
Referring to fig. 4, in the battery cooling mode, the refrigerant in the compressor 110 flows through the reversing valve set 111, then flows to the first heat exchanger 112 and the battery cooler 150 in sequence, and then returns to the compressor 110, and the battery cooler 150 cools the power battery 119 through the first circulating heat exchange system 120. It should be noted that after the refrigerant in the compressor 110 is compressed, the refrigerant flows to the first heat exchanger 112 first and then flows to the battery cooler 150 under the control of the reversing valve set 111, and the refrigerant condenses at the first heat exchanger 112 to release heat and evaporates at the battery cooler 150 to absorb heat; the ambient temperature around the first heat exchanger 112 rises, the ambient temperature at the battery cooler 150 falls, the first circulating heat exchange system 120 exchanges heat with the ambient environment around the battery cooler 150, that is, the air at a lower temperature around the battery cooler 150 can transmit the cold energy to the first circulating heat exchange system 120, the first circulating heat exchange system 120 can transmit the cold energy to the power battery 119, and then the power battery 119 can be cooled and radiated.
In some embodiments, referring to fig. 4, the first circulation heat exchange system 120 includes a first water pump 121 and a first pipeline 122, a heat exchange medium is filled in the first pipeline 122, the first water pump 121 is configured to drive the heat exchange medium to circulate in the first pipeline 122, and when the heat exchange medium flows through the battery cooler 150 and the power battery 119, the battery cooler 150 and the power battery 119 exchange heat with the heat exchange medium. Specifically, the heat exchange medium exchanges heat at the battery cooler 150, and the heat exchanged heat medium flows to the power battery 119 and exchanges heat again at the power battery 119. The heat exchange medium may be water.
For example, as shown in fig. 4, in the battery cooling mode, the refrigerant evaporates and absorbs heat at the battery cooler 150, and the ambient temperature at the battery cooler 150 decreases; the heat exchange medium exchanges heat with the surrounding environment of the battery cooler 150, and the temperature of the heat exchange medium is reduced; the heat exchange medium with a lower temperature flows to the power battery 119 and exchanges heat with the power battery 119, so that the temperature of the power battery 119 is reduced, and the purposes of cooling and radiating the power battery 119 are achieved.
Referring to fig. 1 and 5, according to some embodiments of the present invention, thermal management system 100 may further include a control module 140 and a second cyclic heat exchange system 130, wherein second cyclic heat exchange system 130 is configured to exchange heat with control module 140. Further, taking a vehicle as an example of a blender, referring to fig. 1 and 5, the control module 140 includes an all-in-one module 141, a main drive module 142 and an upper-mounted module 143. The main driving module 142 includes a main driving electric control unit 1421 and a main driving motor 1422; the loading module 143 includes a loading electronic control unit 1431 and a loading motor 1432. Here, the main drive electronic control unit 1421 may control forward, reverse, and the like of the vehicle; the upper electric control unit 1431 can control the stirrer to perform stirring action; the all-in-one module 141 may be a four-in-one controller.
For example, when the mixer is in a running state, the main drive module 142 and the all-in-one module 141 are in a working state, the main drive module 142 and the all-in-one module 141 release heat, and in order to ensure that the main drive module 142 and the all-in-one module 141 work normally, the main drive module 142 and the all-in-one module 141 need to be cooled; when the churn of mixer is in the rotating condition, facial make-up module 143 and all-in-one module 141 are in operating condition, and facial make-up module 143 and all-in-one module 141 will release the heat, in order to guarantee facial make-up module 143 and all-in-one module 141 normal work, need dispel the heat to facial make-up module 143 and all-in-one module 141. Of course, when the mixer is moving and the mixing drum is rotating at the same time, the main driving module 142, the upper mounting module 143 and the all-in-one module 141 are all heat source components, which has a heat dissipation requirement.
To meet the heat dissipation requirements of the vehicle control module 140, in some embodiments, referring to fig. 1 and 5, a second cyclical heat exchange system 130 may be provided. The second circulating heat exchange system 130 comprises a second water pump 131 and a second pipeline 132, a heat exchange medium is filled in the second pipeline 132, the second water pump 131 is used for driving the heat exchange medium to circulate in the second pipeline 132, and when the heat exchange medium flows through the control module 140, the heat exchange medium exchanges heat with the control module 140.
According to some embodiments of the present invention, as illustrated in connection with FIG. 5, the vehicle has an integrated cooling mode. In the integrated refrigeration mode, the battery cooler 150 is connected in parallel with the third heat exchanger 114, and the refrigerant in the compressor 110 flows to the first heat exchanger 112 after passing through the reversing valve group 111, so that a part of the refrigerant flowing out of the first heat exchanger 112 flows to the third heat exchanger 114 and returns to the compressor 110 through the third heat exchanger 114, and the other part of the refrigerant flows to the battery cooler 150 and returns to the compressor 110 through the battery cooler 150. The first circulating heat exchange system 120 exchanges heat with the power battery 119 and the battery cooler 150; the second circulating heat exchange system 130 exchanges heat with the first heat exchanger 112 and the control module 140.
That is, in the integrated cooling mode, the thermal management system 100 may cool the cab, the power battery 119, and the control module 140 at the same time.
According to some embodiments of the present invention, referring to fig. 1 and 2, the thermal management system 100 further comprises an electrical auxiliary thermal assembly 117, the electrical auxiliary thermal assembly 117 being provided at the second heat exchanger 113. In the cab heating mode, when the temperature in the cab cannot satisfy the set temperature, the electric auxiliary heating unit 117 may be used for heat compensation. For example, in winter, the vehicle is just started, the thermal management system 100 switches to the cab heating mode, because the cab temperature is low, the heat released by the second heat exchanger 113 is limited, at this time, the electric auxiliary heating assembly 117 may be started for heat compensation, the heat released by the electric auxiliary heating assembly 117 heats the surrounding environment, so that the surrounding environment of the second heat exchanger 113 is rapidly heated, and under the driving action of the fan 118, air with higher temperature may flow to the cab, so as to increase the speed of the temperature rise of the cab. Further, the electrical auxiliary heating element 117 is an air heater, which may also be referred to as APTC. The air heater not only has simple structure and low price, but also has the advantage of high heating speed.

It should be noted that the heat sink 115 may be a metal heat sink, for example, an aluminum heat sink, and the metal heat sink has the advantages of fast heat conduction and good heat dissipation effect. In some examples, when the vehicle is in the cab cooling mode, the first heat exchanger 112 dissipates heat, the ambient temperature is high, and the heat is not easily diffused by the first heat exchanger 112 itself, and by providing the radiator 115, the heat in the first heat exchanger 112 can be rapidly transferred to the radiator 115, so as to increase the heat dissipation speed, and thus the condensing efficiency of the refrigerant in the first heat exchanger 112 can be improved.
In addition, a partial flow section of the second pipe 132 of the second circulating heat exchange system 130 may be provided at the radiator 115, so that the heat exchange medium in the second pipe 132 may be radiated by the radiator 115. For example, when the vehicle is in the integrated cooling mode, the temperature of the heat exchange medium rises after flowing through the control module 140, and when the heat exchange medium with a higher temperature flows to the radiator 115, the heat of the heat exchange medium can transfer the temperature to the radiator 115, that is, the heat exchange medium can radiate the heat through the radiator 115, so that the temperature of the heat exchange medium can be reduced. Further, in order to improve the heat dissipation effect of the heat sink 115, the fan 118 may be disposed at the heat sink 115, so that the fan 118 may be used to drive the airflow around the heat sink 115 to flow, thereby achieving the purpose of high efficiency of heat dissipation.

In addition, the valve body 151 at different positions may be different types of control valves, for example, the valve body 151 may be a solenoid valve, an electronic expansion valve, an electromagnetic expansion valve, a thermostatic expansion valve with a shut-off function, or the like. The selection of the type of the valve 151 and the connection manner of the liquid storage tank 116 are not particularly limited as long as the requirements of the heat pump cycle for refrigerant circulation and cooling and heating can be satisfied.
