Description
Technical Field
The utility model relates to a traffic field especially relates to an on-vehicle cooling system, supporting cooling system and cooling system.
Background
Hydrogen is used as an energy source material with low energy consumption, low pollution and high energy efficiency, is widely applied to energy source power equipment, and at the present stage, partial automobiles, steamships, airplanes and the like adopt hydrogen as fuel energy. At present, the relatively efficient and safe hydrogen storage technology is alloy hydrogen storage, an alloy hydrogen storage device is a device for storing and releasing hydrogen, and hydrogen storage alloy is arranged in a container inside the device. The hydrogen storage alloy can absorb a large amount of hydrogen at a certain temperature and pressure, and reacts to generate metal hydride, such as TiFe, TiMn, V series metals, lanthanide series metals and the like, and simultaneously releases heat. Thereafter, these metal hydrides are heated, which in turn decompose and release the hydrogen stored therein.
The hydrogen absorption process of the hydrogen storage alloy is mainly divided into three steps: firstly, with the hydrogen continuously filled into the alloy hydrogen storage device, the pressure in the device is increased, the metal absorbs the hydrogen to form a hydrogen-containing solid solution, and the metal phase of the solid solution hydrogen is called as an alpha phase; when the limiting solubility of hydrogen in metals is reached, the alpha phase reacts with hydrogen to form a hydride phase, i.e., the beta phase. In the second step, when the hydrogenation is continued, the pressure of the device is unchanged, and the hydrogen is absorbed by the metal under constant pressure, and the two phases (alpha + beta) are mutually dissolved in the process. Third, when all the alpha phase changes to beta phase, all the metal changes to metal hydride, for example, hydrogen is recharged, the pressure in the device increases significantly, and there is only a small increase in hydrogen in the hydride. The lower the ambient temperature during hydrogen absorption, the lower the pressure of the device when the two phases are mutually dissolved in the second step, and the larger the amount of hydrogen that can be absorbed by the device. Therefore, in order to ensure that the hydrogen storage alloy is continuously and rapidly filled with hydrogen gas when absorbing hydrogen, the device needs to be provided with a cooling system so that the temperature of the device is constantly maintained at a low temperature.
At present, a common cooling system of a vehicle-mounted alloy hydrogen storage device controls a circulating pump to guide cooling water provided by a refrigerating unit into a thermostatic bath according to the temperature monitored by a temperature sensor arranged in the device, and simultaneously discharges redundant heat exchange water until the alloy is saturated by absorbing hydrogen. In this way, on one hand, the system relies on the circulating pump to provide the circulating power of the cooling water, but whether the cooling water in the device flows effectively or not cannot be confirmed; only the temperature sensor is arranged in the device, and the operation of the whole system cannot be accurately monitored and controlled. On the other hand, the refrigerating unit in the method is connected with the heating unit when the alloy hydrogen storage device discharges hydrogen, so that the water temperature change is large in the reaction starting and stopping process of the device, and continuous and rapid hydrogenation of the device cannot be guaranteed; when the alloy hydrogen storage device is installed in equipment together with the alloy hydrogen storage device in use, large space may be occupied, and the space layout of the equipment is limited. The weight of the device is increased, making manufacturing and maintenance costs high.
In summary, there is a need for a cooling system that can improve the hydrogen storage efficiency of an alloy hydrogen storage device and reduce the cost while controlling the temperature accuracy of the cooling liquid.

As shown in fig. 1, the on-board cooling system may include a first connector 210 and a second connector 211, the first connector 210 may be connected to the inlet end of the on-board alloy hydrogen storage device 110 through a first pipe a1, and the second connector 211 may be connected to the outlet end of the alloy hydrogen storage device 110 through a second pipe a 2; the inlet end of the alloy hydrogen storage device 110 can be connected with the outlet end of the alloy hydrogen storage device through a third pipeline (not shown in the figure), and the third pipeline is positioned in the alloy hydrogen storage device 110. The third pipeline may be arranged in different ways according to different types of alloy hydrogen storage devices 110, the third pipeline may be distributed along the inner wall of the alloy hydrogen storage device 110, may be distributed along a container containing hydrogen storage alloy in the alloy hydrogen storage device 110, or may be placed in the third pipeline with the container containing hydrogen storage alloy in the alloy hydrogen storage device 110, and the outer wall of the container directly contacts with the cooling liquid in the third pipeline, which is not limited specifically. Preferably, a container containing hydrogen storage alloy in the alloy hydrogen storage device 110 may be placed in the third conduit. The material, shape and size of the third pipeline can be selected according to actual conditions, and are not particularly limited. Preferably, the liquid inlet end of the alloy hydrogen storage device 110 is positioned at the upper part of the liquid outlet end of the alloy hydrogen storage device 110.

The cooling system may include the on-board cooling system and the complete cooling system, and the cooling liquid provided by the complete cooling system may be used to circulate and cool the on-board cooling system by connecting the first interface 210 and the third interface 310 and connecting the second interface 211 and the fourth interface 311. In practical application, the vehicle-mounted cooling system and the matched cooling system can be arranged in equipment together; the on-board cooling system and the matching cooling system may also be separately disposed, and when the alloy hydrogen storage device 110 needs to store hydrogen, the first interface 210 and the third interface 310, and the second interface 211 and the fourth interface 311 may be used after being connected, and the arrangement of the cooling system in the equipment may be selected according to an actual application scenario, which is not particularly limited.
One application scenario is that the matched cooling system can be arranged on a vehicle together with the vehicle-mounted cooling system, or can be arranged in a hydrogenation station, or can be arranged on a mobile hydrogenation vehicle, or can be independently formed into a device for use, and the like. If the user finds that the hydrogen storage amount of the alloy hydrogen storage device 110 on the vehicle is insufficient, the vehicle can be driven to the hydrogenation station, and the user can also contact with the mobile hydrogenation vehicle or use an independent matched cooling system. Further, the first interface 210 and the third interface 310 are connected, and the second interface 211 and the fourth interface 311 are connected.
In a specific implementation, the circulating liquid pump 312 may sequentially deliver the cooling liquid in the refrigeration device 315 through the sixth pipeline a5, the circulating liquid pump 312, the fourth pipeline a3, the third interface 310, the first interface 210, and the first pipeline a1 to the third pipeline, so as to cool the alloy hydrogen storage device 110 during the hydrogen storage process. The cooling liquid after absorbing heat flows back to the refrigerating device 315 through the second pipeline a2, the second connector 211, the fourth connector 311 and the fifth pipeline a4 in sequence under the power action of the circulating liquid pump 312, so as to form a cooling circulation loop in the hydrogen absorption process of the alloy hydrogen storage device 110. Wherein, the kind of coolant liquid does not do the restriction, can realize heat conduction can, the material of pipeline also has different selections because of coolant liquid and practical application vehicle are different simultaneously, and it is no longer repeated here.
The embodiment of the utility model provides an in, can be provided with first temperature sensor 111 on the third pipeline, can be used to measure the temperature of coolant liquid in the third pipeline. Taking the example that the container containing the hydrogen storage alloy in the alloy hydrogen storage device 110 is placed in the third pipeline, the outer wall of the container is in direct contact with the cooling liquid in the third pipeline, and the temperature of the cooling liquid in the third pipeline can represent the reaction temperature of the alloy hydrogen storage device 110 during hydrogen absorption.
Further, the cooling system may further include a controller (not shown), which may be connected to the first temperature sensor 111. According to different application scenarios of the cooling system, the type, the number and the set position of the controller need to be selected correspondingly and differently, and are not limited specifically.
In a specific implementation, the controller may connect the first interface 210 and the third interface 310, connect the second interface 211 and the fourth interface 311, and start the circulating liquid pump 312 and the refrigeration device 315 after detecting that the temperature of the first temperature sensor 111 is higher than the first threshold. In the second stage of the hydrogen absorption process of the alloy hydrogen storage device 110, i.e. when the hydrogen-containing solid solution formed after the hydrogen absorption of the hydrogen storage alloy further reacts with hydrogen to generate hydride, the lower the temperature in the alloy hydrogen storage device 110, the lower the pressure in the device, and the larger the amount of hydrogen that can be absorbed by the device. The first threshold is the maximum temperature acceptable in the hydrogen absorption reaction process of the alloy hydrogen storage device 110, and when the temperature of the first temperature sensor 111 is higher than the first threshold, the alloy hydrogen storage device 110 cannot stably and rapidly absorb hydrogen. After the hydrogen absorption of the alloy hydrogen storage device 110 is finished, the controller can control the circulating liquid pump 312 and the refrigerating device 315 to stop working. Further, since the recycle pump 312 provides power for the flow of the cooling fluid, the hydraulic pressure of the cooling system exists after the recycle pump 312 and the refrigerating device 315 are stopped, and the system pressure difference can be eliminated by standing.
In the embodiment of the present invention, the first pipeline a1 may be provided with a first flow sensor 213. In one implementation, the first flow sensor 213 can be used to measure the flow rate of the cooling fluid at the inlet end of the alloy hydrogen storage device 110.

The controller may control the circulation fluid pump 312 and the cooling device 315 to stop operating when the flow rate of the cooling fluid measured by the first flow sensor 213 is lower than the second threshold value. In a possible implementation manner, when the first flow sensor 213 detects that the flow rate of the cooling liquid per unit time is higher than the second threshold, it determines that the cooling liquid in the cooling system is flowing effectively, and outputs a cooling liquid effective flowing signal to the controller; if the first flow sensor 213 detects that the flow rate of the cooling liquid in unit time of the cooling liquid is lower than the second threshold, it is determined that the cooling liquid does not flow effectively, and a signal indicating that the cooling liquid does not flow effectively is output to the controller; the controller receives the signal that the cooling liquid does not flow effectively, judges that the cooling system is likely to have a fault, and can stop the operation of the circulating liquid pump 312 and the refrigerating device 315, further stop the operation of the system, and enable a user to carry out maintenance.

The controller can also be connected with the second temperature sensor 214 and the third temperature sensor 212, and adjusts the working speed of the circulating liquid pump 312 and/or the working temperature of the refrigerating device 315 by receiving the temperature in the alloy hydrogen storage device 110 measured by the first temperature sensor 111, the temperature at the liquid outlet end of the alloy hydrogen storage device 110 measured by the second temperature sensor 214 and the temperature at the liquid inlet end of the alloy hydrogen storage device 110 measured by the third temperature sensor 212. Temperature sensors are respectively arranged at the liquid inlet end, the liquid outlet end and the device of the alloy hydrogen storage device 110, compared with the temperature sensor arranged only at the device or at the liquid inlet end or the liquid outlet end, the temperature of the cooling liquid flowing through the alloy hydrogen storage device 110 can be monitored more comprehensively, the temperature of the hydrogen absorption reaction of the alloy hydrogen storage device 110 is further stably maintained, and the rapid and stable hydrogen absorption is realized; meanwhile, potential safety hazards caused by over-high or over-low local temperature in the hydrogen absorption process of the alloy hydrogen storage device 110 can be prevented.

To ensure coolant quality during maintenance or servicing of the system, filter 313 may be removed for cleaning or replacement and re-connected to the water circuit. In order to avoid emptying the cooling liquid in the cooling system during each overhaul or maintenance, the cooling system may further include a second switching device 314, the second switching device 314 may be disposed between the filtering device 313 and the refrigerating device 315, and when the filter element in the filtering device 313 needs to be taken out for cleaning or overhaul, the second switching device 314 may be disconnected without emptying the cooling liquid in the refrigerating device 315, so as to improve the overhaul efficiency and reduce the use cost of the cooling system.
In the embodiment of the present invention, the cooling system is to perform evacuation treatment on the alloy hydrogen storage device 110 for ensuring the sealing performance of the pipeline after the first operation, maintenance or repair.

The sixth port 112 may be provided with a first switching device 113, and the first switching device 113 may be located at a lower portion of the sixth port 112 to block the flow of the cooling fluid through the sixth port 112. According to the practical application scenario, the cooling liquid filling device 410 may be disposed in the hydrogen filling station, or may be disposed in the mobile hydrogen filling station, or may be assembled with a matching cooling system to form a stand-alone device for use, which is not limited specifically.
In a specific implementation, the controller may be further connected to the first switching device 113, and when the fifth interface 411 is connected to the first interface 210, the cooling liquid in the cooling liquid filling device 410 sequentially passes through the seventh pipeline a6, the fifth interface 411, the first interface 210, and the first pipeline a1, and enters the third pipeline. If the sixth port 112 is monitored to have the coolant flowing through, the controller may control the first switching device 113 to turn off, and stop the operation of the coolant filling device 410.
