The present embodiment provides a waste heat utilization device that can heat a cab 101 of a locomotive using waste heat of a hydrogen fuel cell 100.
As shown in fig. 1, the waste heat utilization apparatus may include a cooling pipe 1, a power pump 2, a first distribution valve 3, a first radiator 4, a second radiator 5, a first temperature sensor 6, and a controller 7, wherein:
the cooling pipe 1 may be disposed through the hydrogen fuel cell 100; the inlet end of the cooling pipeline 1 can be communicated with a power pump 2, the power pump 2 is used for driving the cooling liquid in the cooling pipeline 1 to flow, and the outlet end of the cooling pipeline 1 can be communicated with the inlet end of a first distribution valve 3; the first outlet end of the first distribution valve 3 may communicate with the inlet end of the first radiator 4, and the outlet end of the first radiator 4 may communicate with the inlet end of the second radiator 5; the second outlet end of the first distribution valve 3 may communicate with the inlet end of the second radiator 5, and the outlet end of the second radiator 5 may communicate with the power pump 2, thereby forming a complete circulation loop.
Therefore, the temperature of the cooling liquid in the cooling pipeline 1 rises after absorbing the heat generated by the hydrogen fuel cell 100 during the reaction, and the cooling liquid flows into the first radiator 4 through the first distribution valve 3, and the first radiator 4 can release the heat carried by the cooling liquid to the cab 101, so that the heating problem of the cab 101 in winter is solved, and the waste heat of the hydrogen fuel cell 100 is recycled.
Meanwhile, the first radiator 4 may be disposed inside the cab 101; the second radiator 5 can be arranged outside the cab 101; the first temperature sensor 6 can be arranged in the cab 101 and used for measuring a first temperature value in the cab 101; the controller 7 may be connected to the first distribution valve 3 and the first temperature sensor 6 for adjusting the coolant flow distributed by the first distribution valve 3 to the first radiator 4 and the second radiator 5 in dependence on the measured first temperature value.
Therefore, the exhaust heat utilization device according to the embodiment of the present disclosure can perform closed-loop control of the flow rate of the cooling liquid in the first radiator 4, thereby achieving automatic adjustment of the temperature in the cab 101 and optimal operation of the hydrogen fuel cell 100.
In summary, the waste heat utilization device according to the embodiment of the present disclosure not only reduces the waste of heat of the hydrogen fuel cell 100, but also reduces the hydrogen fuel consumption of the locomotive, thereby realizing green, energy-saving and intelligent operation of the locomotive.
The components of the test apparatus provided in the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings:
as shown in fig. 1, a cooling fluid may flow through the cooling pipe 1, for example, the cooling fluid may be deionized water, so as to prevent scale from appearing on the inner wall of the cooling pipe 1.
The cooling pipe 1 may be disposed through the hydrogen fuel cell 100, so that the coolant with a relatively low temperature can absorb heat generated during the reaction of the hydrogen fuel cell 100, thereby reducing the temperature of the hydrogen fuel cell 100.
The inlet end of the cooling pipeline 1 can be communicated with a power pump 2, the power pump 2 is used for driving the cooling liquid in the cooling pipeline 1 to flow, the actual specification of the power pump 2 is subject to the requirement of meeting the use requirement, and no special limitation is made here; the outlet end of the cooling duct 1 can communicate with the inlet end of a first distribution valve 3, which first distribution valve 3 is used to distribute the flow of cooling liquid, as shown in fig. 1, the first distribution valve 3 having two outlet ends, wherein:
the first outlet end of the first distribution valve 3 may communicate with the inlet end of the first radiator 4, and the outlet end of the first radiator 4 may communicate with the inlet end of the second radiator 5; the second outlet end of the first distribution valve 3 may communicate with the inlet end of the second radiator 5, while the outlet end of the second radiator 5 communicates with the power pump 2.
Therefore, the cooling pipeline 1, the power pump 2, the first distribution valve 3, the first radiator 4 and the second radiator 5 form a complete circulation loop, so that the cooling liquid which absorbs heat and is heated in the cooling pipeline 1 can release the heat through the first radiator 4 and the second radiator 5 and return to the cooling pipeline 1 through the power pump 2, and the waste heat utilization device of the embodiment of the disclosure can work in a circulating and reciprocating mode.
The first radiator 4 may be disposed in the cab 101 to provide heating for the cab 101. For example, the first heat sink 4 may be a heat sink or a ground heating pipe, and accordingly, when the first heat sink 4 is a heat sink, the first heat sink 4 needs to be installed on a wall inside the cab 101; when the first radiator 4 is a ground heating pipe, the first radiator 4 needs to be installed under the floor in the cab 101, and at this time, not only the heat dissipation effect is better, but also the space in the cab 101 is saved.
The second radiator 5 may be disposed outside the cab 101 to adjust the temperature inside the cab 101. For example, the second heat sink 5 may include heat dissipation fins, and of course, in order to better dissipate heat outdoors, the second heat sink 5 may further include a fan, and the rotation speed of the fan may be adjusted, so as to adjust the heat dissipation efficiency of the second heat sink 5.
In summary, if the temperature in the cab 101 is high, the flow rate of the coolant flowing into the first radiator 4 can be reduced by the first distribution valve 3, so that more heat is released to the outside of the cab 101; if the temperature in the cab 101 is low, the flow rate of the coolant flowing into the first radiator 4 can be increased by the first distribution valve 3, so that more heat is released into the cab 101.
Of course, in summer when the temperature is high, all the coolant can be returned to the power pump 2 via the second radiator 5, which will not be described in detail here.
In order to achieve precise control of the coolant flow rate, as shown in fig. 1, the waste heat utilization apparatus of the embodiment of the present disclosure may further include a first temperature sensor 6 and a controller 7, wherein:
the first temperature sensor 6 can be arranged in the cab 101 and used for measuring a first temperature value in the cab 101; the controller 7 may be connected to the first distribution valve 3 and the first temperature sensor 6 for adjusting the coolant flow distributed by the first distribution valve 3 to the first radiator 4 in dependence on the measured first temperature value.
At the same time, the controller 7 may have a temperature setting module, by means of which an operator can set a first predetermined value of the first temperature value. For example, the first predetermined value may be 26 ℃, but may be higher than 26 ℃ or lower than 26 ℃, and is not particularly limited herein.
Thus, when the measured first temperature value is lower than the first predetermined value, the controller 7 controls the first distribution valve 3 to increase the flow rate of the coolant flowing into the first radiator 4; when the measured first temperature value is higher than a first predetermined value, the controller 7 controls the first distribution valve 3 to turn down the flow rate of the coolant flowing into the first radiator 4.
As shown in fig. 2, the waste heat utilization apparatus of the embodiment of the present disclosure may further include a second temperature sensor 8 and a third temperature sensor 9, wherein:
the second temperature sensor 8 can be arranged at the inlet end of the cooling pipeline 1 and is used for measuring a second temperature value of the cooling liquid at the inlet end of the cooling pipeline 1; the third temperature sensor 9 can be arranged at the outlet end of the cooling pipeline 1 and is used for measuring a third temperature value of the cooling liquid at the outlet end of the cooling pipeline 1;
of course, the second temperature sensor 8 and the third temperature sensor 9 are both connected to the controller 7, and the controller 7 can adjust the flow rate of the coolant distributed to the first radiator 4 by the first distribution valve 3 according to the measured first temperature value, the measured second temperature value, and the measured third temperature value, and the specific adjustment process will not be described in detail here.
As previously mentioned, the controller 7 may have a temperature setting module which is also capable of setting a second predetermined value of the second temperature value and a third predetermined value of the third temperature value. For example, the second predetermined value may be set to about 70 ℃ and the third predetermined value may be set to about 80 ℃, so that the controller 7 can control and adjust the entire circulation circuit based on the first predetermined value, the second predetermined value, and the third predetermined value.
In addition, the second heat sink 5 may include a heat sink and a fan with adjustable rotation speed, and therefore, the fan may be further connected to the controller 7, so that the controller 7 can adjust the rotation speed of the fan according to the measured first, second and third temperature values, and a specific adjustment process will not be described in detail herein.
As shown in fig. 2, the waste heat utilization apparatus of the embodiment of the present disclosure may further include a second distribution valve 10, an inlet end of the second distribution valve 10 may be communicated with a second outlet end of the first distribution valve 3, a first outlet end of the second distribution valve 10 may be communicated with an inlet end of the second radiator 5, and a second outlet end of the second distribution valve 10 may be communicated with the power pump 2.
Of course, the second distribution valve 10 is also connected to the controller 7, and the controller 7 is capable of adjusting the coolant flow distributed by the second distribution valve 10 to the second radiator 5 according to the measured first, second and third temperature values, and the specific adjustment process will not be described in detail here.
This corresponds to the addition of parallel branches to the flow circuit, which further increases the stability and reliability of the overall waste heat utilization device.
As shown in fig. 2, the waste heat utilization apparatus of the embodiment of the present disclosure may further include an accumulator 11, where one end of the accumulator 11 may be communicated with the inlet end of the second radiator 5, and the other end may be communicated with the power pump 2, so as to adjust the volume of the cooling liquid in the cooling pipe 1.
The liquid storage 11 may be a common container, and the pressure inside the liquid storage may be a standard atmospheric pressure value, and when the pressure inside the cooling pipe 1 is greater than the standard atmospheric pressure value, the cooling liquid inside the cooling pipe 1 can automatically flow into the liquid storage 11 under the action of the pressure difference, so as to reduce the cooling liquid in the whole circulation loop.
Of course, the waste heat utilization apparatus according to the embodiment of the present disclosure may further include a pressure sensor 12, and the pressure sensor 12 may be disposed between the liquid reservoir 11 and the power pump 2 for measuring the pressure in the cooling pipe 1, and at the same time, both the pressure sensor 12 and the power pump 2 may be connected to the controller 7.
Thus, when the pressure in the cooling pipe 1 is lower than the standard atmospheric pressure, the controller 7 can control the power pump 2 to pump the cooling fluid in the reservoir 11 to the whole circulation circuit, thereby increasing the cooling fluid in the cooling pipe 1.
It is to be understood that the disclosure is not limited in its application to the details of construction and the arrangements of the components set forth in the specification. The present disclosure is capable of other embodiments and of being practiced and carried out in various ways.
