[0002] Currently, most hydrogen fuel cell vehicles on the market utilize independent cooling and drainage systems, lacking comprehensive management and efficient utilization of heat and water resources. Cooling systems often dissipate generated heat into the environment through air or liquid cooling, which not only wastes energy but also potentially causes thermal pollution to the surrounding environment. Furthermore, drainage systems often directly discharge generated water to the outside, failing to recycle water resources and increasing dependence on and consumption of external water resources.

[0003] Therefore, developing a hydrogen fuel cell vehicle system that can efficiently utilize the heat and water resources generated by hydrogen generators has become a pressing technical challenge. This utility model, based on this background, proposes an innovative hydrogen fuel cell vehicle design. By introducing components such as heat exchangers and heating jackets, it achieves comprehensive management and efficient utilization of heat and water resources, improving the overall performance and environmental benefits of the hydrogen fuel cell vehicle.

DETAILED DESCRIPTION

[0019] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims. Example

[0020] See also Figures 1 to 4 :

[0021] A water circulation system for a hydrogen fuel cell vehicle includes a heat exchanger 2, a heating jacket 3, a hydrogen energy generator 4, and a water storage tank 1. The heat exchanger 2 has two heat exchange flow channels, one flow channel includes a first water inlet 20 and a first water outlet 21, and the other flow channel includes a second water inlet 22 and a second water outlet 23. The first water inlet 20 of the heat exchanger 2 is connected to the water outlet of the hydrogen energy generator 4, the first water outlet 21 of the heat exchanger 2 is connected to the first interface of the water storage tank 1, the second water inlet 22 of the heat exchanger 2 is connected to the second interface of the water storage tank 1, and a water pump 6 is also provided on the connecting pipe. The second water outlet 23 of the heat exchanger 2 is connected to the heating jacket water inlet 30 of the heating jacket 3, and the heating jacket water outlet 31 of the heating jacket 3 is connected to the third interface of the water storage tank 1.

[0022] The utility model utilizes the heat exchanger 2 to exchange heat generated by the hydrogen energy generator 4 with the water in the water storage tank 1, thereby reducing the heat dissipation pressure of the hydrogen energy fuel cell vehicle, and recycling the water generated by the hydrogen energy generator 4 into the water storage tank 1, realizing the collection and utilization of the water generated by the hydrogen energy generator 4. The water flowing out of the water storage tank 1 is heated by heat exchange in the heat exchanger 2, and then flows into the heating jacket 3, heating the hydrogen tank 7 in the heating jacket 3 to realize the utilization of waste heat, and finally flows back to the water storage tank 1 from the heating jacket 3, realizing a cycle.

[0023] Furthermore, the first interface, the second interface and the third interface of the water storage tank 1 are respectively a collection port 10 for water generated by the hydrogen energy generator 4, a water delivery port 12 for delivering water through the water pump 6 and a recovery port 11 for recovering water flowing out of the water storage tank 1. The water delivery port 12 of the water storage tank 1 is connected to the water suction port of the water pump 6 that provides power, the output port of the water pump 6 is connected to the second water inlet 22 of the heat exchanger 2, and the collection port 10 of the water storage tank 1 is connected to the first water outlet 21 of the heat exchanger 2.

[0024] The collecting port 10 is used to receive water generated by the hydrogen energy generator 4, the water supply port 12 provides water to the heat exchanger 2 through the water pump 6, and the recovery port 11 is used to receive water treated by the heat exchanger 2 and the heating jacket 3, thereby realizing the recycling of water.

[0025] Furthermore, the heating sleeve 3 is divided into an upper sleeve 33 and a lower sleeve 34 , and semicircular grooves 37 are provided on the opposing surfaces of the upper sleeve 33 and the lower sleeve 34 . When the opposing surfaces of the upper sleeve 33 and the lower sleeve 34 contact, the two semicircular grooves 37 form a cylindrical cavity 36 capable of accommodating the hydrogen tank 7 .

[0026] The two semicircular grooves 37 can completely correspond to and form a complete cylindrical cavity 36 to accommodate the hydrogen tank 7, which helps to ensure that the hydrogen tank 7 is evenly heated during the heating process and improve the heating efficiency.

[0027] Furthermore, the heating jacket water inlet 30 and the heating jacket water outlet 31 of the heating jacket 3 are arranged in the upper jacket 33 or the lower jacket 34 , and there is a flow channel between the heating jacket water inlet 30 and the heating jacket water outlet 31 , and the flow channel is isolated from the cylindrical cavity 36 that can accommodate the hydrogen tank 7 .

[0028] The arrangement of the water inlet 30 and the water outlet 31 of the heating jacket ensures the flow and circulation of the liquid, thereby achieving continuous heating of the hydrogen tank 7 .

[0029] Furthermore, the upper sleeve 33 and the lower sleeve 34 are connected by a hinge 32, and a lock 35 for fixing the upper sleeve 33 and the lower sleeve 34 is provided on the opposite surface of the hinge surface.

[0030] The heating jacket 3 is divided into an upper jacket 33 and a lower jacket 34 and connected by a hinge 32 so that the heating jacket 3 can be opened and closed conveniently. The hydrogen tank 7 can be easily placed in the heating jacket 3. At the same time, the lock 35 can ensure that the upper jacket 33 and the lower jacket 34 fit tightly together when closed, preventing the hydrogen tank 7 from sliding off due to vibration or external force during the heating process, thereby improving safety and stability.

[0031] Further,

[0032] Flow limiting valves 5 are provided at the first water outlet 21 of the heat exchanger 2 and the water outlet of the heating jacket 3 .

[0033] Providing a flow limiting valve 5 at the first water outlet 21 of the heat exchanger 2 ensures that the water generated by the hydrogen energy generator 4 has sufficient time to undergo heat exchange in the heat exchanger 2, thereby improving heat exchange efficiency. Providing a flow limiting valve 5 at the water outlet of the heating jacket 3 prolongs the residence time of the water in the heating jacket 3, allowing the hydrogen tank 7 to be more fully heated, thereby improving the efficiency and performance of the entire water circulation system.

[0034] The principle of this utility model is:

[0035] The device uses a water storage tank 1 as the water storage end of the entire water circulation system, including water delivery and water recovery. The water delivery port 12 of the water storage tank 1 is connected to the water pump 6, and the other end of the water pump 6 is connected to the second water inlet 22 of the heat exchanger 2, so that the water in the water storage tank 1 passes through the water pump 6 through the second water inlet 22 into the heat exchanger 2 and flows out from the second water outlet 23 of the heat exchanger 2. The water outlet of the hydrogen energy generator 4 is connected to the first water inlet 20 of the heat exchanger 2, so that the water generated by the hydrogen energy generator 4 during operation enters the heat exchanger 2 from the first water inlet 20 and flows out from the heat exchanger 2 from the first water outlet 21. In this way, the water in the water storage tank 1 and the water generated by the hydrogen energy generator 4 continuously exchange heat in the heat exchanger 2, reducing the heat dissipation pressure of the hydrogen energy fuel cell vehicle;

[0036] The water generated by the hydrogen energy generator 4 during operation flows out from the first water outlet 21 of the heat exchanger 2 and then enters the water storage tank 1 along the pipeline from the collecting port 10 of the water storage tank 1. The water generated by the hydrogen energy generator 4 is collected and reused.

[0037] The water in the water storage tank 1 flows out of the heat exchanger 2 from the first water outlet 21 and enters the heating jacket 3 through the pipeline from the heating jacket water inlet 30 of the lower jacket 34 of the heating jacket 3. The heat obtained from the heat exchanger 2 is used to heat the hydrogen tank 7 in the heating jacket 3. Because the hydrogen tank 7 has the maximum hydrogen output efficiency at around 50 degrees Celsius, the waste heat is utilized. The water then flows out from the heating jacket water outlet 31 on the lower jacket 34 through the pipeline and enters the water storage tank 1 from the recovery port 11 of the water storage tank 1, completing the entire water circulation.

[0038] Since the circulating water will evaporate due to heat during the circulation process, collecting the water generated in the hydrogen energy generator 4 reduces the frequency of replenishing the water storage tank 1 to a certain extent.
