Description

Technical Field

[0001] This utility model relates to the field of hydrogen energy battery heat dissipation technology, specifically a hydrogen energy-powered battery heat dissipation system. Background Technology

[0002] Hydrogen fuel cells generate heat during operation. Specifically, the main reasons for this heat generation include: In the process of converting chemical energy into electrical energy, the reaction is not entirely efficient; some energy is lost as heat, causing the cell to heat up. Additionally, the electrodes and electrolytes inside the cell have resistance, and when current flows through them, heat is generated according to Joule's law. While this heat generation is a normal characteristic of hydrogen fuel cells, excessively high temperatures can cause a series of problems, such as reduced battery performance, accelerated aging, and safety hazards. To maintain the normal operation of hydrogen fuel cells and extend their lifespan, effective measures must be taken to control the cell temperature.

[0003] The patent document, published under CN216793741U, entitled "A Fuel Cell for a Hydrogen Energy Vehicle with Temperature Control Function," describes a method where the internal heat is transferred downwards through an external battery block frame and a heat-conducting base plate, concentrating the heat onto a heat-conducting copper busbar. Water cooling is achieved through water-cooled recesses and heat dissipation pipes on both sides of the copper busbar, and a water pump facilitates internal coolant recirculation. However, after prolonged use, the coolant temperature rises, and this existing technology cannot effectively cool the coolant, resulting in a decrease in subsequent battery cooling efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a hydrogen-powered battery heat dissipation system, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrogen energy-powered battery heat dissipation system, comprising a battery, wherein a heat-conducting frame is provided on the outside of the battery, and the bottom of the heat-conducting frame is connected to a heat dissipation copper busbar provided on the bottom of the battery; the heat-conducting frame is detachably connected to a fixed cover, the bottom of the fixed cover is detachably connected to a base, both ends of the base are detachably connected to filter covers, and a cooling fan is provided inside one of the filter covers;

[0006] The base has a support rod at its top, and a liquid storage tank and a pump are located at the top of the support rod. The pump is connected to the bottom of the liquid storage tank and has a liquid delivery pipe connected to it. The liquid delivery pipe is connected to the inlet of the first heat dissipation copper busbar, the outlet of the first heat dissipation copper busbar is connected to a transmission pipe, the transmission pipe is connected to the inlet of the second heat dissipation copper busbar, the outlet of the second heat dissipation copper busbar is connected to a return pipe, and the return pipe is connected to a cover detachably connected to the top of the liquid storage tank. The top of the cover has a fixing rod connected to the second heat dissipation copper busbar.

[0007] Preferably, the first heat dissipation copper busbar is located above the second heat dissipation copper busbar, and the first heat dissipation copper busbar, the second heat dissipation copper busbar, the liquid storage tank and the tank cover are all located inside the fixed cover.

[0008] Preferably, a baffle is detachably connected to the top inner wall of the liquid storage tank, and drainage holes are provided around the baffle.

[0009] Preferably, ventilation holes are evenly provided on both sides of the liquid storage tank, and the ventilation holes are located below the baffle.

[0010] Preferably, the inner wall of the liquid storage tank is horizontally welded with a ventilation pipe, and the axis of the ventilation pipe coincides with the axis of the ventilation hole, and the diameter of the ventilation pipe is larger than the diameter of the ventilation hole.

[0011] Preferably, the fixed cover is provided with a liquid filling pipe and a pipe cap, and the liquid filling pipe is connected to the liquid storage tank.

[0012] This invention provides a heat dissipation system for a hydrogen-powered battery. Compared with the prior art, it has the following advantages:

[0013] 1. In this hydrogen-powered battery cooling system, coolant is drawn from the storage tank and enters the first heat dissipation copper busbar through the delivery pipe, which cools the first heat dissipation copper busbar. The heated coolant is then transferred to the second heat dissipation copper busbar through the transmission pipe for further cooling. After cooling is complete, the coolant falls through the return pipe between the tank cover and the baffle, where it can be cooled through the tank cover. Finally, it falls back into the storage tank through the drainage holes around the tank. The cooling fan accelerates the airflow from one side of the fixed cover to the other, which can speed up the airflow around the first and second heat dissipation copper busbars, the tank cover, and the storage tank. This helps to cool the battery and coolant, so that the battery can still maintain a cooling effect after long-term use.

[0014] 2. In this hydrogen-powered battery cooling system, when the airflow inside the fixed cover flows rapidly, it can pass through the ventilation holes and enter the ventilation pipe, thereby cooling the coolant in the storage tank more closely through the ventilation pipe, further improving the cooling efficiency of the coolant.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figures 1-4 This utility model provides the following two technical solutions:

[0022] First embodiment: A hydrogen energy-powered battery heat dissipation system includes a battery 1, a heat-conducting frame 2 is provided on the outside of the battery 1, and the bottom of the heat-conducting frame 2 is connected to a heat dissipation copper busbar 3 provided on the bottom of the battery 1, which can dissipate the heat on the battery 1; the heat-conducting frame 2 is detachably connected to a fixed cover 4, the bottom of the fixed cover 4 is detachably connected to a base 5, both ends of the base 5 are detachably connected to a filter cover 6, and a cooling fan is provided in one side of the filter cover 6, which is powered and controlled by existing technology, and the filter cover 6 is used to prevent dust from entering during ventilation;

[0023] The base 5 has a support rod 7 on top, and a liquid storage tank 9 and a pump 8 are located on top of the support rod 7. The support rod 7 makes the bottom of the liquid storage tank 9 suspended for heat dissipation. The pump 8 is connected to the bottom of the liquid storage tank 9 and has a liquid delivery pipe 10 connected to it. The liquid delivery pipe 10 is connected to the inlet of the first heat dissipation copper busbar 3. The outlet of the first heat dissipation copper busbar 3 is connected to the transmission pipe 11. The transmission pipe 11 is connected to the inlet of the second heat dissipation copper busbar 12. The outlet of the second heat dissipation copper busbar 12 is connected to the return pipe 13. The return pipe 13 is connected to the cover 14 detachably connected to the top of the liquid storage tank 9. The top of the cover 14 has a fixing rod 15 connected to the second heat dissipation copper busbar 12. The fixing rod 15 makes the bottom of the second heat dissipation copper busbar 12 suspended, which facilitates heat dissipation of the second heat dissipation copper busbar 12 and the cover 14. The cover 14 and the liquid storage tank 9 are both made of copper-aluminum alloy, which has good heat dissipation effect.

[0024] The first heat dissipation copper busbar 3 is located above the second heat dissipation copper busbar 12, so that the two are suspended in the air, which facilitates the passage of airflow. The first heat dissipation copper busbar 3, the second heat dissipation copper busbar 12, the liquid storage tank 9 and the tank cover 14 are all located inside the fixed cover 4, which facilitates the subsequent airflow to dissipate heat from the first heat dissipation copper busbar 3, the second heat dissipation copper busbar 12, the liquid storage tank 9 and the tank cover 14.

[0025] A baffle 16 is detachably connected to the top inner wall of the liquid storage tank 9. Drain holes 17 are provided around the baffle 16, which can allow the coolant returning to the liquid storage tank 9 to be discharged through the drain holes 17. When flowing through the baffle 16, the coolant will come into contact with the tank cover 14 because the baffle 16 is close to the tank cover 14, and thus can dissipate heat with the help of the tank cover 14.

[0026] Ventilation holes 18 are evenly provided on both sides of the liquid storage tank 9, and the ventilation holes 18 are located below the baffle 16. A ventilation pipe 19 made of copper-aluminum alloy is horizontally welded to the inner wall of the liquid storage tank 9, so that the ventilation pipe 19 can be in closer contact with the coolant in the liquid storage tank 9, which is convenient for dissipating more heat from the coolant in the liquid storage tank 9. The axis of the ventilation pipe 19 coincides with the axis of the ventilation hole 18. The diameter of the ventilation pipe 19 is larger than the diameter of the ventilation hole 18, which is convenient for welding the ventilation pipe 19, so that the coolant will not enter the ventilation hole 18. When the airflow passes through the ventilation hole 18 and the ventilation pipe 19, it can cool the ventilation pipe 19, thereby increasing the heat dissipation area of ​​the coolant.

[0027] The second embodiment differs from the first embodiment in that: a liquid filling pipe 20 is provided on the fixed cover 4, and a pipe cap is provided on the liquid filling pipe 20, and the liquid filling pipe 20 is connected to the liquid storage tank 9.

[0028] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0029] According to existing technology, the cooling fan and pump 8 are activated in a timely manner. For example, the temperature of battery 1 is detected by existing temperature detection technology. The heat emitted from the periphery of battery 1 can be transferred to the heat dissipation copper busbar 3 through the heat conduction frame 2. The heat at its bottom can be directly transferred to the heat dissipation copper busbar 3, which is the same as existing technology. Then, under the action of pump 8, the coolant is drawn out through the reservoir 9 and enters the heat dissipation copper busbar 3 through the delivery pipe 10, which can cool the heat dissipation copper busbar 3. The heated coolant is then transferred to the heat dissipation copper busbar 12 through the transmission pipe 11 for heat dissipation. After heat dissipation, it falls through the return pipe 13 to the tank cover 14 and the baffle 16. The airflow can then be dissipated through the contact cover 14, and then fall back into the storage tank 9 through the drain holes 17 around the perimeter. The cooling fan accelerates the airflow from one side of the fixed cover 4 to the other side, which can speed up the airflow around the cooling copper busbar 1 3, cooling copper busbar 2 12, cover 14 and storage tank 9, thereby assisting the battery 1 and coolant in cooling down. When the airflow in the fixed cover 4 flows rapidly, it can pass through the ventilation hole 18 and enter the ventilation pipe 19, so that the coolant in the storage tank 9 can be cooled down more closely. Therefore, even after the battery 1 has been used for a long time, the coolant can still ensure the cooling effect on the battery 1.
