Description

Technical Field

[0001] This utility model relates to the field of hydrogen fuel cell technology, specifically a heat dissipation module for hydrogen energy vehicle batteries. Background Technology

[0002] A hydrogen fuel cell is a device that generates electricity through a chemical reaction between hydrogen and oxygen. Also known as a proton exchange membrane fuel cell, it is widely used in electric vehicle charging stations, automobiles, and other power generation facilities due to its high efficiency, zero emissions, and zero pollution. During operation, hydrogen fuel cells release a large amount of heat, of which electrochemical reaction heat accounts for about 55%, irreversible electrochemical reaction heat accounts for 35%, Joule heat accounts for about 10%, and condensation heat and various heat losses account for about 5%. If this heat is not dissipated in time, it will not only affect the reaction process but also the lifespan of the fuel cell. Therefore, a heat dissipation module needs to be installed to dissipate the heat.

[0003] The patent document with patent number CN202321239091.5, entitled "A Heat Dissipation Structure for a Hydrogen Fuel Cell", describes a method of placing a hydrogen fuel cell inside a groove for fixation and then using circulating coolant to dissipate heat from the casing. The heat is then carried away from the hydrogen fuel cell inside the groove through heat transfer. However, due to the irregular shape of the hydrogen fuel cell casing, the inner wall of the groove cannot fully contact the casing, resulting in poor heat dissipation through heat transfer. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a heat dissipation module for hydrogen fuel cell vehicles, which solves the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a heat dissipation module for hydrogen energy vehicle batteries, including a fixing slot and a fan, wherein the inner wall of the fixing slot is provided with a fixing block for mounting a hydrogen fuel cell, and the bottom of the fixing slot is provided with a support foot; The mounting slot is provided with a mounting component for mounting a fan, and the fan is located below the mounting block; An air inlet slot is provided on one side of the bottom of the fixed slot. Two heat conduction plates are installed alternately below the fan in the fixed slot. Horizontal S-shaped flow channels are also provided inside the heat conduction plates. A transmission pipe is connected between the two S-shaped flow channels. Both S-shaped flow channels are connected to the coolant delivery assembly.

[0006] Preferably, vertical plates are evenly arranged on the bottom heat-conducting plate, and inclined plates are evenly arranged on the opposite sides of the top heat-conducting plate and the bottom heat-conducting plate, with the inclined plates facing the direction of airflow.

[0007] Preferably, the coolant delivery assembly includes a delivery pipe connected to the bottom heat-conducting plate and a discharge pipe connected to the top heat-conducting plate. A coolant box is provided on one side support leg, and a delivery pump is connected to the coolant box. The delivery pump is connected to the delivery pipe.

[0008] Preferably, the coolant box is further provided with a liquid cooling radiator, which is connected to the drain pipe and has a recovery pipe connected to the coolant box.

[0009] Preferably, a filter screen is provided on the air inlet slot, and a blocking screen is provided on the inner wall of the fixing slot, with the blocking screen positioned between the fixing block and the fan.

[0010] Preferably, the mounting assembly includes a support rod disposed on the inner wall of the fixing groove, a support column disposed on the top of the support rod, the fan being sleeved on the support column, and the fan also having screws for connecting to the support column.

[0011] This invention provides a heat dissipation module for hydrogen fuel cell vehicles. Compared with existing technologies, it has the following advantages: 1. This heat dissipation module for hydrogen fuel cell vehicles delivers coolant to the S-shaped flow channels within two heat-conducting plates via a coolant delivery assembly, which cools the heat-conducting plates. Then, after the external airflow passes through the air inlet slot, it can pass along the S-shaped direction through the upper and lower heat-conducting plates, thus achieving sufficient heat exchange with the heat-conducting plates and cooling the external airflow. The cooled airflow is then blown upwards onto the hydrogen fuel cell by a fan. Compared with existing technologies, this module has a better heat dissipation effect and can improve the heat dissipation efficiency of the hydrogen fuel cell.

[0012] 2. In this heat dissipation module for hydrogen fuel cell vehicles, when the airflow passes between two heat-conducting plates, the vertical and inclined plates allow the airflow to flow further along an S-shaped path, resulting in better cooling by the two heat-conducting plates. The inclined plates also allow the airflow to have a longer contact time with the heat-conducting plate above it, and can also direct the airflow to the leeward side of the vertical plate, thus enabling better heat exchange with the inclined plates, vertical plates, and the heat-conducting plate above, resulting in a better cooling effect on the airflow.

[0015] 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.

[0016] See Figures 1-4 This utility model provides the following two technical solutions: First embodiment: A heat dissipation module for hydrogen fuel cell vehicle battery, including a fixing slot 1 and a fan 3 powered and controlled by existing technology. The inner wall of the fixing slot 1 is provided with a fixing block 2 for mounting a hydrogen fuel cell, so that the hydrogen fuel cell can be located in the fixing slot 1. The bottom of the fixing slot 1 is provided with a support leg 12 for fixing the fixing slot 1 and also for suspending the bottom of the fixing slot 1 to allow air intake 4 to enter. The mounting slot 1 is provided with a mounting component for mounting the fan 3, and the fan 3 is located below the mounting block 2; An air inlet slot 4 is provided on one side of the bottom of the fixed slot 1. Two heat conduction plates 5 are installed alternately below the fan 3 in the fixed slot 1, and horizontal S-shaped flow channels 6 are provided in the heat conduction plates 5. A transmission pipe 7 connects the two S-shaped flow channels 6. Both S-shaped flow channels 6 are connected to the coolant delivery assembly. With the help of the coolant delivery assembly and the transmission pipe 7, coolant can enter the S-shaped flow channels 6 in both heat conduction plates 5 to complete the cooling of the heat conduction plates 5. After the outside airflow passes through the air inlet slot 4, it can pass through the upper and lower heat conduction plates 5 along the S-shaped direction, and can fully exchange heat with the heat conduction plates 5 to achieve the purpose of cooling the outside airflow. The cooled airflow is blown towards the hydrogen fuel cell, and the heat dissipation effect is better.

[0017] Vertical plates 10 are evenly arranged on the bottom heat-conducting plate 5, and inclined plates 11 are evenly arranged on the opposite sides of the top heat-conducting plate 5 and the bottom heat-conducting plate 5. The inclined plates 11 are opposite to the airflow direction. When the airflow passes between the two heat-conducting plates 5, it can flow further along the S-shaped path through the vertical plates 10 and the inclined plates 11, and be cooled better by the two heat-conducting plates 5. Furthermore, the obstruction of the inclined plates 11 makes the contact time between the airflow and the inclined plates 11 and the upper heat-conducting plate 5 longer, and also allows the airflow to blow to the leeward side of the vertical plates 10, thereby better exchanging heat with the inclined plates 11, the vertical plates 10 and the upper heat-conducting plate 5.

[0018] The coolant delivery assembly includes a delivery pipe 8 connected to the bottom heat-conducting plate 5 and a discharge pipe 9 connected to the top heat-conducting plate 5. A coolant box 13 is provided on one side support 12, and a delivery pump 14 is connected to the coolant box 13. The delivery pump 14 is connected to the delivery pipe 8. In order to cool the recovered coolant, a liquid cooler 15 is also provided on the coolant box 13. The liquid cooler 15 is connected to the discharge pipe 9, and a recovery pipe 16 connected to the coolant box 13 is provided on the liquid cooler 15.

[0019] The air inlet slot 4 is equipped with a filter screen 17 for filtering dust, and the inner wall of the fixed slot 1 is equipped with a blocking screen 18 for blocking impurities above. The blocking screen 18 is located between the fixed block 2 and the fan 3.

[0020] The second embodiment differs from the first embodiment in that the mounting assembly includes a support rod 19 disposed on the inner wall of the fixing groove 1, a support column 20 disposed on the top of the support rod 19, the fan 3 is sleeved on the support column 20, and the fan 3 is also provided with a screw 21 connected to the support column 20. The support column 20 guides the fan 3 to facilitate the installation of the screw 21.

[0021] 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.

[0022] In use, the coolant flows through the S-shaped flow channel 6 within the heat-conducting plate 5, carrying away the heat from the heat-conducting plate 5. When the fan 3 is working, the outside airflow is drawn in by the air inlet slot 4 and passes through the upper and lower heat-conducting plates 5 along the S-shaped direction, thus achieving sufficient heat exchange with the heat-conducting plates 5 to cool the outside airflow. When the airflow passes between the two heat-conducting plates 5, it passes through the vertical plate 10 and the inclined plate 11, allowing the airflow to flow further along the S-shaped path and be cooled better by the two heat-conducting plates 5. Furthermore, the obstruction of the inclined plate 11 allows the airflow to have a longer contact time with the inclined plate 11 and the upper heat-conducting plate 5, and also allows the airflow to be blown to the leeward side of the vertical plate 10, thus achieving better heat exchange with the inclined plate 11, the vertical plate 10, and the upper heat-conducting plate 5, resulting in a better cooling effect on the airflow. After being fully cooled, the outside airflow is guided along the inner wall of the fixed slot 1 by the fan 3 and blown towards the hydrogen fuel cell above to dissipate heat.
