Description

Technical Field

[0001] The present invention relates to the technical field of fuel cell heat dissipation housings, and in particular to a heat dissipation housing for a fuel cell of a new energy vehicle. Background Art

[0002] A fuel cell is a device that directly converts the chemical energy of a fuel (such as hydrogen, methanol, or natural gas) and an oxidant (usually oxygen) into electricity. Its operating principle is based on an electrochemical reaction, which is accelerated by a catalyst, efficiently converting the fuel's chemical energy into electricity without the need for combustion. This characteristic distinguishes it from traditional heat engines, avoiding the limitations of the Carnot cycle. Its theoretical efficiency can reach 60%-80%, far exceeding the 30%-40% of an internal combustion engine. It is commonly used as a power battery in new energy vehicles, and can be fully charged in just 3-5 minutes when hydrogen is added. The fuel cell's heat sink housing is the shell that houses and dissipates heat from the battery.

[0003] However, conventional fuel cells for new energy vehicles are installed and dissipated through a heat dissipation housing (the battery heat dissipation housing reference is the battery heat dissipation housing disclosed in patent publication number CN222654065U). The battery is placed between two sets of heat dissipation pipes, and a fan blows air away the heat from the heat dissipation pipes to dissipate the heat from the battery. The battery is secured on both sides by only two clamps installed on the top plate. No fixing mechanism is provided between the ends of the two sets of heat dissipation pipes and the battery, thereby only dissipating heat. However, the vehicle vibrates significantly during driving, and the other two sides of the battery are not secured, which can easily cause the battery to shake, resulting in poor contact and affecting normal power supply. Two sets of clamps are then slid onto the top plate and fixed with screws. The waist-shaped grooves on the top plate for sliding the clamps can only clamp batteries of different sizes. No support assembly is provided at the bottom of the clamps, resulting in poor clamping effect for the clamps and the clamps easily sliding on the top plate, which also affects the stability of the battery. When cooling the battery through the vehicle's air conditioning, no detection equipment is provided on the battery, making it difficult to connect the air conditioning at the correct time. This not only affects the battery's heat dissipation effect but also easily results in waste of cold air. Summary of the Invention

[0004] In response to the problems in the prior art, the present invention provides a heat dissipation housing for a fuel cell of a new energy vehicle.

Two mounting frames are installed inside the shell, and multiple fans are installed at equal distances on the two mounting frames. The shell is provided with two groups of air inlets connected to the air outlet 2 inside the heat dissipation pipe, and the opposite surfaces of the two groups of heat dissipation pipes are provided with a waist-shaped air outlet.

[0008] Specifically, the air cooling mechanism 1 further includes an air guide plate, and the side wall of the shell is welded with an air guide plate with an isosceles trapezoidal structure, and the air guide plate is located between the two mounting frames.

[0009] Specifically, the air cooling mechanism 1 further includes a filter and a pressure plate. The filter is plugged into the shell with the side wall opening. The pressure plate is fixedly connected to the top center of the filter, and the top of the pressure plate is an arc-shaped structure.

[0010] Specifically, the second air cooling mechanism also includes a hydraulic rod, which is installed at the top center of the shell, and the telescopic end of the hydraulic rod is fixedly connected to a sealing plate by screws, and sliding columns are welded at the four corners of the side of the sealing plate. The sliding columns are slidingly connected to the shell, and a controller is installed on the shell. A temperature sensor is installed on the side wall of the battery, and the controller is electrically connected to the temperature sensor, and the controller is connected to the hydraulic rod. Two air inlet pipes are installed on the top of the shell, and the top of the pressure plate is slidingly connected to the telescopic part of the hydraulic rod.

[0011] Specifically, two water-cooling mechanisms are relatively installed on the shell, and the water-cooling mechanisms include liquid cooling plates. Two liquid cooling plates are relatively welded on the shell, and the opposite surfaces of the two liquid cooling plates are bonded with thermal conductive silicone, and the thermal conductive silicone contacts the battery. The interiors of the two liquid cooling plates are both S-shaped and provided with liquid cooling cavities, and the two liquid cooling plates are both threadedly connected with connecting pipes that are connected to the two ends of the liquid cooling cavity.

[0012] Specifically, the clamping mechanism includes a slide groove, and two slide grooves with convex cross-sections are opened on the sides of the shell relative to each other. The interiors of the two slide grooves are slidably connected to two slide bars with T-shaped structures, and the ends of the two slide bars are rotatably connected to a clamping plate with an L-shaped structure.

[0015] The beneficial effects of the present invention are:

[0016] (1) The present invention relates to a fuel cell heat dissipation housing for a new energy vehicle. A fixing mechanism is installed on the air cooling mechanism. When installing the battery, the battery is placed between the two groups of heat dissipation pipes, and the side of the battery is in contact with the housing. When dissipating heat from the battery, the fan is started, the sealing plate is in an open state, the heat dissipation pipe absorbs the heat of the battery, and the fan blows away the heat on the heat dissipation pipe to complete the heat dissipation. Further, the two groups of clamping columns on the fixing plate are inserted into the interior of the two groups of heat dissipation pipes. The clamping columns and the heat dissipation pipes are fixed by the four outermost limiting columns in conjunction with the limiting holes on the clamping columns and the heat dissipation pipes, thereby achieving heat dissipation while clamping and fixing both sides of the battery, thereby increasing the stability of the battery.

[0017] (2) The present invention relates to a fuel cell heat dissipation housing for a new energy vehicle. The air cooling mechanism 1 is relatively installed with two clamping mechanisms. After the battery is fixed by the clamping column on the upper end of the fixed plate, four mounting blocks are installed on both sides of the battery, and spring 2 is clamped between the four mounting blocks and the corresponding slide bars. At this time, spring 2 is in a contracted state. The clamping plate at the end of the slide bar is rotated to achieve the correspondence between the clamping plate and the limit plate on the side wall of the fixed plate, and the two slide bars on the same side are relatively squeezed. At this time, the slide bar drives the two clamping plates to contact the limit plate, and the two slide bars are squeezed and limited by the buckle plate and the card slot. The spring 2 cannot be reset, so the two sets of slide bars can achieve the clamping and fixing of the other two sides of the battery, thereby increasing the stability of the battery and preventing the battery from shaking when the vehicle is driving, causing poor contact and affecting normal power supply.

[0018] (3) The present invention relates to a heat dissipation housing for a fuel cell of a new energy vehicle. An air cooling mechanism 2 is installed on the housing. When the temperature of the battery is too high and the air cooling mechanism 1 cannot quickly cool the battery, the temperature sensor located on the side of the battery can transmit the temperature signal to the controller on the housing. The controller can control the hydraulic rod to contract. When the hydraulic rod contracts, the sealing plate contacts the housing, thereby sealing the side opening of the housing. The air inlet pipe located on the housing is connected to the air conditioning duct of the vehicle. After the air conditioning is refrigerated, the cold air is discharged to the interior of multiple heat dissipation pipes through the air inlet. Further cold air is discharged from the air outlet 1 on the two groups of heat dissipation pipes to contact the top and bottom of the battery, thereby quickly cooling the battery and facilitating the normal use of the battery. The telescopic part of the hydraulic rod can press the pressure plate, thereby facilitating the fixing of the filter. When removing the filter, it is only necessary to remove the screws of the sealing plate and the telescopic part of the hydraulic rod, and then the filter can be pulled out for cleaning.

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] like Figures 1-10As shown, the heat dissipation housing of a new energy vehicle fuel cell according to the present invention comprises a battery 1, an air cooling mechanism 2 arranged on the outside of the battery 1, an air cooling mechanism 2 5, a fixing mechanism 3 and a clamping mechanism 6 are installed on the air cooling mechanism 2; the air cooling mechanism 2 comprises a shell 201, one side of the battery 1 is in contact with the shell 201, two groups of heat dissipation pipes 202 are welded on the shell 201 at equal distances, and the two groups of heat dissipation pipes 202 are respectively in contact with the top and bottom of the battery 1; the fixing mechanism 3 comprises two groups of clamping columns 303 and an air outlet 304, and both groups of heat dissipation pipes 202 are provided with an air outlet. The second outlet 304 of the two groups of heat pipes 202 is plugged with a card column 303 inside. A fixing plate 301 is welded between the two upper and lower opposite card columns 303. The two adjacent fixing plates 301 are welded by a connecting plate 302. The four outermost heat pipes 202 and the card columns 303 are all provided with limiting holes 309. The insides of the four card columns 303 are all fixedly connected to the inner plate 305. The four inner plates 305 are all fixedly connected to the fixing columns 306. The insides of the four fixing columns 306 are all slidably connected to the limiting columns 308. The limiting columns 308 and The clamping column 303 and the limiting hole 309 on the heat pipe 202 are buckled, and a spring 307 is clamped between the fixing column 306 and the limiting column 308; the clamping column 303 and the heat pipe 202 are both hollow hexagonal prism structures, and the length of the clamping column 303 is less than the length of the heat pipe 202; the air cooling mechanism 2 also includes a mounting frame 204, a fan 205, an air inlet 208 and an air outlet 207. Two mounting frames 204 are installed inside the housing 201, and multiple fans 205 are installed on the two mounting frames 204 at equal distances. Two groups of fans 205 are opened on the housing 201 to meet the heat pipe 202. The internal air outlet 204 is connected to the air inlet 208, and the opposite surfaces of the two groups of heat pipes 202 are each provided with a waist-shaped air outlet 207; the air cooling mechanism 1 2 also includes an air guide plate 206, which is welded to the side wall of the housing 201 and has an isosceles trapezoidal structure. The air guide plate 206 is located between the two mounting brackets 204; the air cooling mechanism 1 2 also includes a filter 203 and a pressure plate 209. The filter 203 is plugged into the housing 201 with an opening on the side wall. The pressure plate 209 is fixedly connected to the center of the top of the filter 203, and the top of the pressure plate 209 has an arc-shaped structure.When installing the battery 1, first fix the bottom liquid cooling plate 401 and the shell 201 to the vehicle body to complete the connection between the overall structure and the vehicle body to prevent the overall structure from shaking when the vehicle is driving. Place the battery 1 between the two sets of heat pipes 202, so that the side of the battery 1 contacts the side of the shell 201, and the thickness of the battery 1 is less than the distance between the two sets of air inlets 208, so as to prevent the battery 1 from blocking the air inlet 208. When cooling the battery 1, ensure that the hydraulic rod 503 is in the extended state, and the sealing plate 50 2 The housing 201 is not sealed, and multiple fans 205 on the two mounting brackets 204 are started. After the fans 205 are started, they draw air in, and the air is blown into the interior of the heat pipe 202 from the air inlet 208. Since the top and bottom of the two groups of heat pipes 202 are oppositely provided with air outlets 207, the air blown by the fans 205 will blow the top and bottom of the battery 1 from the air outlet 207 to achieve heat dissipation on the top and bottom of the battery 1. The air outlet 2 304 inside the heat pipe 202 is responsible for exhausting the hot air, completing the air cooling and heat dissipation of the battery 1. Hold the two limiting plates 607 in one step, and insert the clamping posts 303 at both ends of the multiple fixing plates 301 into the interior of the air outlet 2 304 on the multiple heat pipes 202, and the fixing plates 301 and the connecting plates 302 are in contact with the side of the battery 1. When the clamping posts 303 are inserted into the interior of the heat pipe 202, the limiting posts 308 will be squeezed due to the spring 1 307 provided inside the fixing posts 306. When the heat pipe 202 corresponds to the limiting hole 309 on the clamping posts 303, the fixing posts 306 are not squeezed, and the spring 1 307 is provided inside the fixing posts 306. 7 is opened, and the fixing column 306 is now inserted into the limiting hole 309 on the heat pipe 202 and the clamping column 303, completing the position of the clamping column 303. The clamping column 303 also has a second air outlet 304, which ensures the exhaust of hot air while installing the fixing plate 301, and increases the stability of the installation on both sides of the battery 1. During air cooling, the air generated by the two sets of fans 205 can be guided by the air guide plate 206, which helps the air blow into the air inlet 208 and ultimately flows into the heat pipe 202 for heat dissipation.

[0033] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8As shown, the air cooling mechanism 2 5 also includes a hydraulic rod 503, which is installed at the top center of the shell 201. The telescopic end of the hydraulic rod 503 is fixedly connected to the sealing plate 502 by screws. Slide columns 501 are welded at the four corners of the side of the sealing plate 502. The slide columns 501 are slidably connected to the shell 201. A controller 504 is installed on the shell 201. A temperature sensor 505 is installed on the side wall of the battery 1. The controller 504 is electrically connected to the temperature sensor 505, and the controller 504 is connected to the hydraulic rod 503. The shell 201 is Two air inlet pipes 506 are installed on the top, and the top of the pressure plate 209 is slidably connected to the telescopic part of the hydraulic rod 503; when the natural wind and water cooling have a slow heat dissipation effect on the battery 1, as the temperature of the battery 1 increases, the temperature sensor 505 located on its side can detect the temperature of the battery 1. When the temperature is high, the temperature sensor 505 transmits the received signal to the controller 504, and the controller 504 controls the hydraulic rod 503 to contract, and the sealing plate 502 contacts the shell 201 to seal the opening on the side of the shell 201. The two air inlet pipes 506 are connected to the air conditioning pipes on the car, which can cool the air conditioner and realize that the cold air enters the interior of the shell 201 from the air inlet pipe 506. The cold air further enters the interior of the two sets of heat pipes 202 from the air inlet 208. Since the battery 1 is connected to the air outlet 207 on the two sets of heat pipes 202, the cold air can be discharged from the air outlet 207 on the heat pipe 202 and contact the top and bottom of the battery 1, completing the heat dissipation of the battery 1. Whether it is natural air cooling or the heat dissipation of the car air conditioner, the air after inhalation is discharged from the air outlet 207. 4 is discharged. After the temperature sensor 505 detects that the temperature of the battery 1 drops to a certain temperature, the controller 504 can control the sealing plate 502 to open, and the fan 205 blows air to dissipate heat naturally, which can save energy consumption. When the filter 203 plugged into the housing 201 needs to be disassembled and cleaned, the screws on the sealing plate 502 can be removed. At this time, the sealing plate 502 will not prevent the hydraulic rod 503 from retracting into place. When the telescopic end of the hydraulic rod 503 passes over the pressure plate 209 on the filter 203, the filter 203 can be pulled out for cleaning.

[0034] Specifically, such as Figure 1 、 Figure 2 and Figure 3As shown, two water cooling mechanisms 4 are relatively installed on the shell 201. The water cooling mechanism 4 includes a liquid cooling plate 401. Two liquid cooling plates 401 are relatively welded on the shell 201. The opposite surfaces of the two liquid cooling plates 401 are bonded with thermal conductive silicone 402. The thermal conductive silicone 402 is in contact with the battery 1. The interiors of the two liquid cooling plates 401 are both S-shaped and provided with a liquid cooling cavity 404. The two liquid cooling plates 401 are both threadedly connected with a connecting pipe 403 that is connected to the two ends of the liquid cooling cavity 404. The two liquid cooling plates 401 are relatively installed on the shell 201. The liquid cooling plate 401 on the bottom side can be connected to the The outer shell 201 supports the overall structure, and the opposite surfaces of the two liquid cooling plates 401 are bonded with thermal conductive silicone 402 to absorb the heat from the two groups of heat pipes 202. When the car is working, a water cooling system dissipates heat from the engine. One of the connecting pipes 403 on the two liquid cooling plates 401 is connected to the cold water pipe of the car's water cooling system, and the other connecting pipe 403 on the two liquid cooling plates 401 is connected to the return pipe of the car's water cooling system to realize water circulation, which can take away part of the heat from the heat pipe 202 and improve the heat dissipation effect on the battery 1.

[0035] Specifically, such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 and Figure 10As shown, the clamping mechanism 6 includes a slide groove 601. Two slide grooves 601 with a convex cross-section are provided on the sides of the housing 201. Two slide bars 602 with a T-shaped structure are slidably connected to the inside of the two slide grooves 601. The ends of the two slide bars 602 are rotatably connected to a clamping plate 606 with an L-shaped structure. The side walls of the two outermost fixed plates 301 are welded with a limiting plate 607 with an L-shaped structure. The limiting plate 607 is in conflict with the clamping plate 606. The clamping mechanism 6 also includes a mounting block 608. , both sides of the battery 1 are rectangular and have four mounting blocks 608 fixed by screws, and springs 603 are clamped between the four mounting blocks 608 and the two slides 602 on the same side; the clamping mechanism 6 also includes a slot 604 and a buckle plate 605, and the top and bottom of the two slides 602 on the same side are provided with a slot 604, and the two slots 604 on the same side are buckled and connected with a buckle plate 605; when the two sides of the battery 1 are installed and fixed, the battery 1 is installed, but the other two sides of the battery 1 are not. Align and fix, and when the battery 1 is installed, the clamping plates 606 at the ends of the four slides 602 are rotated to face each other, so that the clamping plates 606 are flush with the side walls of the slide 602 and will not block the installation of the battery 1. The two springs 603 are in a contracted state. After the two sides of the battery 1 are fixed, the four clamping plates 606 are rotated back to their original positions, and four mounting blocks 608 are installed on both sides of the battery 1 by screws to install the springs 603. The two slides 602 on the same side are further squeezed relative to each other. At this time, the same The two clamping plates 606 on the side move relative to each other, and the limiting plate 607 is inserted into the limiting plate 607 on the side wall of the two fixed plates 301, thereby realizing the fixation of the slide 602 to the other two sides of the battery 1. The two buckle plates 605 are respectively placed on the two slides 602 on the same side, and the squeezing of the slide 602 is released. The spring 2 603 is reset, and the buckle plate 605 limits the two slides 602 to prevent the movement of the slide 602 from causing the clamping plate 606 to separate from the limiting plate 607, thereby increasing the stability of the installation of the battery 1.

[0036] When using the present invention, first, when installing the battery 1, the bottom liquid cooling plate 401 and the shell 201 must be fixed to the vehicle body to complete the connection between the overall structure and the vehicle body, so as to prevent the overall structure from shaking when the vehicle is driving. The battery 1 is placed between the two groups of heat pipes 202, and the side of the battery 1 is in conflict with the side of the shell 201. The thickness of the battery 1 is less than the distance between the two groups of air inlets 208, so as to prevent the battery 1 from blocking the air inlet 208. When the battery 1 is cooled by air, the hydraulic rod 503 is ensured to be extended. In the state, the sealing plate 502 does not seal the shell 201, and the multiple fans 205 on the two mounting frames 204 are started. After the fans 205 are started, they suck air, and the air is blown into the interior of the heat pipe 202 from the air inlet 208. Since the top and bottom of the two groups of heat pipes 202 are oppositely provided with air outlets 207, the air blown by the fans 205 will blow the top and bottom of the battery 1 from the air outlet 207 to achieve heat dissipation on the top and bottom of the battery 1. The air outlet 2 304 inside the heat pipe 202 is responsible for exhausting the hot air, completing the air dissipation of the battery 1. To dissipate heat, further hold the two limiting plates 607, and insert the clamping columns 303 at both ends of the multiple fixing plates 301 into the interior of the air outlet 2 304 on the multiple heat pipes 202, and the fixing plates 301 and the connecting plates 302 are in contact with the side of the battery 1. When the clamping column 303 is inserted into the interior of the heat pipe 202, the limiting column 308 will be squeezed due to the spring 1 307 provided inside the fixing column 306. When the heat pipe 202 corresponds to the limiting hole 309 on the clamping column 303, the fixing column 306 is not squeezed, and the spring 1 The first 307 is opened, and the fixing column 306 is inserted into the limiting hole 309 on the heat pipe 202 and the clamping column 303, completing the positioning of the clamping column 303. The clamping column 303 is also penetrated by the second air outlet 304, which ensures the exhaust of hot air while installing the fixing plate 301, and increases the stability of the installation on both sides of the battery 1. When cooling, the wind generated by the two sets of fans 205 can be guided by the wind guide plate 206, which helps the wind blow into the inside of the air inlet 208 and finally flows into the heat pipe 202 for heat dissipation.

[0037] Then, when both natural wind and water cooling have a slow heat dissipation effect on the battery 1, as the temperature of the battery 1 rises, the temperature sensor 505 located on its side can detect the temperature of the battery 1. When the temperature is high, the temperature sensor 505 transmits the received signal to the controller 504. The controller 504 controls the hydraulic rod 503 to contract, and the sealing plate 502 contacts the shell 201 to seal the opening on the side of the shell 201. Since the two air inlet pipes 506 on the shell 201 are connected to the air-conditioning pipes on the car, the air conditioner can be refrigerated, and the cold air can enter the interior of the shell 201 from the air inlet pipe 506, and further the cold air enters the interior of the two groups of heat pipes 202 from the air inlet 208. Since the battery 1 is connected to the air outlet 207 on the two groups of heat pipes 202, the cold air can The air is discharged from the first air outlet 207 on the heat dissipation pipe 202 and contacts the top and bottom of the battery 1 to complete the heat dissipation of the battery 1. Whether it is natural air cooling or the heat dissipation of the car air conditioner, the air after being inhaled is discharged from the second air outlet 304. After the temperature sensor 505 detects that the temperature of the battery 1 drops to a certain temperature, the controller 504 can control the sealing plate 502 to open, and the fan 205 blows air to dissipate the heat by natural wind, which can save energy. When the filter 203 plugged into the housing 201 needs to be removed for cleaning, the screws on the sealing plate 502 can be removed. At this time, the sealing plate 502 will not prevent the hydraulic rod 503 from retracting into place. When the telescopic end of the hydraulic rod 503 passes over the pressure plate 209 on the filter 203, the filter 203 can be pulled out for cleaning.

[0038] Next, two liquid cooling plates 401 are mounted opposite each other on the outer shell 201. The liquid cooling plate 401 on the bottom side can support the entire structure together with the outer shell 201. Thermally conductive silicone rubber 402 is bonded to the opposing surfaces of the two liquid cooling plates 401 to absorb heat from the two sets of heat pipes 202. When the car is working, a water cooling system dissipates heat from the engine. One of the connecting pipes 403 on the two liquid cooling plates 401 is connected to the cold water pipe of the car's water cooling system, and the other connecting pipe 403 on the two liquid cooling plates 401 is connected to the return water pipe of the car's water cooling system to achieve water circulation, which can remove some of the heat from the heat pipes 202 and improve the heat dissipation effect on the battery 1.

[0039] Finally, when two sides of the battery 1 are installed and fixed, the battery 1 is installed. However, the other two sides of the battery 1 are not aligned and fixed. When the battery 1 is installed, the clamping plates 606 at the ends of the four slides 602 are rotated to face each other. Then, the clamping plates 606 are flush with the side walls of the slide 602 and will not block the installation of the battery 1. The two springs 603 are in a contracted state. After the two sides of the battery 1 are fixed, the four clamping plates 606 are rotated and reset. Four mounting blocks 608 are installed on both sides of the battery 1 by screws to install the springs 603. The two slides 602 on the same side are squeezed relative to each other. At this time, the two clamps 606 on the same side move relative to each other, and the limit plate 607 is inserted into the limit plate 607 on the side walls of the two fixed plates 301, thereby achieving the fixation of the slide 602 on the other two sides of the battery 1. The two buckle plates 605 are placed on the two slides 602 on the same side respectively, and the squeezing of the slide 602 is released. The spring 2 603 is reset, and the buckle plate 605 limits the two slides 602 to prevent the slide 602 from moving and causing the clamp 606 to separate from the limit plate 607, thereby increasing the stability of the installation of the battery 1.
