Description

Technical Field

[0001] The present invention relates to the technical field of radiators, and in particular to an aluminum alloy radiator for a power supply component of a new energy vehicle. Background Art

[0002] The power supply components of new energy vehicles are key components that convert new energy into electrical energy and provide power. The power supply components are usually composed of power batteries, chargers, charging interfaces, motors and controllers, electric compressors, power electronics, high-voltage distribution boxes and battery management systems. Among them, for the most common pure electric vehicles, the battery modules, battery management systems, high-voltage distribution boxes and charging interfaces in their power supply components are all installed together to form a battery pack. Due to the large number of battery cells in the battery module, heat is generated when in operation. In order to effectively manage the thermal state of the battery module, a radiator is usually connected to the bottom of the battery mold for heat dissipation.

[0003] The radiators in the battery packs of existing new energy vehicles often use aluminum alloy liquid cooling plates for thermal management. Heat is exchanged between the liquid cooling plate and the battery module, and the coolant in the vehicle's cooling system is circulated through pipes into the liquid cooling plate, so that the coolant removes the heat from the liquid cooling plate, achieving the effect of timely heat dissipation from the battery module. The liquid cooling plate is usually installed at the bottom of the battery module and is shielded and protected by a lower cover. However, when the car is driving on complex roads, the rugged road surface can easily cause a collision with the lower cover, and the impact of the lower cover is directly transferred to the liquid cooling plate. Since the hollow structure of the liquid cooling plate often deforms or even breaks and leaks when it is hit, it is difficult to maintain continuous heat dissipation from the battery module. Summary of the Invention

[0004] The purpose of the present invention is to provide an aluminum alloy radiator for a new energy vehicle power supply component to solve the problems raised in the above background technology.

[0005] The heat dissipation device is connected with the heat dissipation device by the upper end face of the heat dissipation device, and the heat dissipation device is connected with the heat dissipation device by the upper end face of the heat dissipation device.

[0006] Preferably, the mounting frame is in the shape of a rectangular frame, and the mounting frame is located below the radiator body and the connecting edge. There are a plurality of fixing columns, which are arranged at equal intervals on the upper surface of the mounting frame.

[0007] Preferably, a sliding groove is provided on the connecting edge, a first spring is provided on the outside of the fixing column between the connecting edge and the radiator body, the connecting edge is in the shape of a rectangular frame with an L-shaped cross section, the connecting edge is inserted into the interior of the radiator body and forms a sliding connection with the inner wall of the radiator body.

[0008] Preferably, a slot is provided at the bottom of the radiator body above the fixing column, a first through hole is provided inside the radiator body above the slot, and the fixing column passes through the connecting edge and the first spring and is movably connected to the slot.

[0009] Preferably, mounting bolts are provided through the first through hole, the center hole and the second through hole, and the mounting frame, the connecting edge and the radiator body are all mounted on the bottom of the battery pack by the mounting bolts.

[0010] Preferably, one side of the water bag is connected to a first liquid inlet pipe, and the other side of the water bag is connected to a connecting pipe. The interior of the water bag is hollow and filled with coolant. The connecting pipe passes through the lower cover and is connected to the second liquid inlet pipe. The water bag is connected to the coolant circulation groove through the connecting pipe and the second liquid inlet pipe.

[0011] Preferably, the pressure relief assembly includes a pressure relief seat installed on the side wall of the radiator body, a liquid passage is opened inside the pressure relief seat, a piston plate is slidably connected to the inside of the pressure relief seat below the liquid passage, a second spring is connected to the bottom of the piston plate, and an exhaust hole is opened through the side wall of the pressure relief seat below the second spring.

[0012] Preferably, both sides of the liquid passage are communicated with the first liquid outlet pipe and the second liquid outlet pipe respectively, and the middle of the liquid passage is communicated with the inner cavity of the pressure relief seat.

[0013] Preferably, the upper and lower ends of the second spring are respectively connected to the piston plate and the inner wall of the pressure relief seat. When the second spring is in a normal stretched state, the upper surface of the piston plate is flush with the bottom of the liquid channel, and the inner cavity of the pressure relief seat is connected to the external environment through the exhaust hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The aluminum alloy radiator of the power supply component of this new energy vehicle is provided with a connecting edge, a first spring and a water bag. When the road collides with the lower cover during the driving of the new energy vehicle, the lower cover is subjected to an upward thrust, and the lower cover drives the connecting edge to move upward inside the radiator body, so that the connecting edge moves upward relative to the fixed column to squeeze the first spring. The compression of the first spring provides a preliminary buffering of the collision, thereby reducing the impact of the collision of the lower cover on the radiator body. When the lower cover moves upward and drives the water bag to contact the radiator body, the water bag provides a secondary buffering of the collision. The water bag is filled with coolant, which has a good impact resistance effect and can effectively prevent the radiator body from being deformed, broken or even leaking due to collision.

[0015] 2. The aluminum alloy radiator of the power supply component of this new energy vehicle is equipped with a connecting pipe and a first liquid inlet pipe. The coolant in the vehicle cooling system is introduced into the water bag through the first liquid inlet pipe. The coolant flows in the water bag and is introduced into the coolant circulation groove from the second liquid inlet pipe through the connecting pipe. The coolant exchanges heat with the radiator body in the coolant circulation groove. The coolant in the water bag circulates. On the one hand, the circulating coolant is used for heat exchange in the radiator body and for collision buffering in the water bag. On the other hand, the heat transferred to the water bag from the bottom of the radiator body is taken out in time to avoid the high temperature environment affecting the service life of the water bag.

[0016] 3. The aluminum alloy radiator of the power supply component of this new energy vehicle is provided with a pressure relief component. When the water bag contacts the radiator body for buffering, the pressure in the water bag cavity increases sharply, pushing the internal coolant quickly from the connecting pipe into the coolant flow groove, and the coolant then flows into the liquid channel from the first liquid outlet pipe. The pressure of the coolant pushes the piston plate down in the pressure relief seat, and the second spring is compressed to make the coolant flow into the pressure relief seat, reducing the pressure of the coolant. The air in the pressure relief seat is discharged from the exhaust hole. After the collision, the inside of the water bag 5 is in a negative pressure state, and the rebound force of the second spring pushes the piston plate up, and the piston plate pushes the coolant back to achieve the effect of pressure relief during the water bag buffering process.

[0017] 4. The aluminum alloy radiator of the power supply component of this new energy vehicle is equipped with a mounting frame and a fixing column. The mounting frame is used to limit the connecting edge, so that the lower cover can slide up and down in the radiator body through the connecting edge. The mounting frame, the connecting edge and the radiator body are all connected to the battery pack synchronously through the mounting bolts. By removing the mounting bolts, the connecting edge and the lower cover can be quickly removed, which is convenient for maintenance of the water bag and achieves the effect of quick disassembly and assembly of the radiator body.

[0023] like Figures 1 to 6As shown, the aluminum alloy radiator of the new energy vehicle power supply component in this embodiment includes a radiator body 1, a lower cover 2 is provided below the radiator body 1, and the edges of the upper surface of the lower cover 2 are connected with connecting edges 3. After the lower cover 2 is connected to the connecting edge 3, a recessed space is formed on its upper surface, and the water bag 5 is installed in the recessed space. A mounting frame 4 is provided below the connecting edge 3, and the mounting frame 4 is used to limit the bottom of the connecting edge 3 so that the connecting edge 3 can drive the lower cover 2 to rise and fall in the radiator body 1 for buffering. The upper surface of the lower cover 2 is connected with a water bag 5, and the water bag 5 is made of elastic material to ensure its buffering effect. A coolant flow groove 6 arranged in an S-shaped zigzag pattern is provided inside the radiator body 1. The heat on the radiator body 1 is taken out by passing coolant into the coolant flow groove 6. A second liquid inlet pipe 7 is installed inside the radiator body 1 on one side of the coolant flow groove 6. It is used to introduce coolant into the coolant circulation groove 6. A first liquid outlet pipe 8 is installed inside the radiator body 1 on the other side of the coolant circulation groove 6 for discharging the coolant in the coolant circulation groove 6. A pressure relief component 9 is installed on the side of the radiator body 1 close to the first liquid outlet pipe 8 for relieving pressure when the water bag 5 is under pressure. The side wall of the pressure relief component 9 is connected to the second liquid outlet pipe 10. A fixing column 41 is connected to the upper surface of the mounting frame 4. The fixing column 41 passes through the connecting edge 3, which is used for guiding the lifting and lowering of the connecting edge 3 and for increasing the accuracy of the installation of the connecting edge 3 and the radiator body 1. A center hole 42 is opened through the middle of the fixing column 41, and a second through hole 43 is opened through the mounting frame 4 below the fixing column 41. The radiator body 1 is bent downward at right angles on all sides to form a rectangular cover, providing sufficient buffer space for the connecting edge 3 to move upward when colliding with the lower cover 2.

[0024] Specifically, the mounting frame 4 is in the shape of a rectangular frame. The mounting frame 4 is located below the radiator body 1 and the connecting edge 3. The inner wall of the mounting frame 4 is in contact with the connecting edge 3 and the outer wall of the lower cover 2. The outer wall of the mounting frame 4 is flush with the side wall of the radiator body 1. There are several fixing columns 41, which are arranged equidistantly on the upper surface of the mounting frame 4.

[0025] Furthermore, a slide groove 31 is provided on the connecting edge 3, and the outer diameter of the fixing column 41 is matched with the inner diameter of the slide groove 31. The fixing column 41 passes through the connecting edge 3 through the slide groove 31, and the slide groove 31 slides relative to the fixing column 41 during the lifting and lowering process of the connecting edge 3. A first spring 44 is provided on the outer side of the fixing column 41 between the connecting edge 3 and the radiator body 1. When the first spring 44 is in a normal tension state, the bottom of the connecting edge 3 contacts the mounting frame 4. The connecting edge 3 is a rectangular frame with an L-shaped cross section. The connecting edge 3 is inserted into the interior of the radiator body 1 and forms a sliding connection with the inner wall of the radiator body 1. When the road collides with the lower cover 2 during the driving of the new energy vehicle, the lower cover 2 drives the connecting edge 3 to move upward in the radiator body 1, and the compression of the first spring 44 performs preliminary buffering on the collision, thereby reducing the impact of the collision of the lower cover 2 on the radiator body 1.

[0026] Furthermore, a slot 101 is provided at the bottom of the radiator body 1 above the fixing column 41, and the top of the fixing column 41 is inserted into the slot 101 to maintain the accuracy of the combination of the mounting frame 4, the connecting edge 3 and the radiator body 1. A first through hole 102 is provided inside the radiator body 1 above the slot 101, and the fixing column 41 passes through the connecting edge 3 and the first spring 44 and is movably connected to the slot 101, wherein the number of the first through hole 102, the second through hole 43, the slide groove 31 and the first spring 44 are all several, and correspond one-to-one to the position of the fixing column 41.

[0027] Furthermore, mounting bolts 45 are provided through the first through hole 102, the center hole 42 and the second through hole 43. The mounting frame 4, the connecting edge 3 and the radiator body 1 are all mounted on the bottom of the battery pack by the mounting bolts 45. The mounting bolts 45 are used to combine the mounting frame 4, the connecting edge 3 and the radiator body 1, and are also used to simultaneously mount the above three on the bottom of the battery pack. By removing the mounting bolts 45, the connecting edge 3 and the lower cover 2 can be quickly removed, making it convenient to maintain the water bag 5.

[0028] Furthermore, a first liquid inlet pipe 51 is connected to one side of the water bag 5, and the car's cooling system supplies coolant to the first liquid inlet pipe 51, wherein the car's cooling system is usually installed in the front box of the car, and includes a box for storing coolant, a liquid pump and a heat dissipation structure. The structural composition of the cooling system and the method of discharging the coolant into the radiator body 1 are both existing technologies. A connecting pipe 52 is connected to the other side of the water bag 5, which is used to connect the coolant circulation groove 6 and the water bag 5. The interior of the water bag 5 is hollow and filled with coolant. The connecting pipe 52 passes through the lower cover 2 and is connected to the second liquid inlet pipe 7. The water bag 5 is connected to the coolant circulation groove 6 through the connecting pipe 52 and the second liquid inlet pipe 7. Because the water bag 5 is very close to the radiator body 1, it is inevitable that heat will be transferred to the water bag 5. The coolant in the water bag 5 takes out the small amount of heat in the water bag 5, and is passed from the connecting pipe 52 and the second liquid inlet pipe 7 into the coolant circulation groove 6 for heat exchange with the radiator body 1.

[0029] Furthermore, the pressure relief assembly 9 includes a pressure relief seat 91 installed on the side wall of the radiator body 1. The pressure relief seat 91 is in the shape of a rectangular plate with a hollow interior. A liquid passage 92 is provided inside the pressure relief seat 91 to ensure that the coolant in the first liquid outlet pipe 8 is discharged from the second liquid outlet pipe 10 through the liquid passage 92. A piston plate 93 is slidably connected to the inside of the pressure relief seat 91 below the liquid passage 92. The piston plate 93 separates the upper and lower spaces of the inner cavity of the pressure relief seat 91. The piston plate 93 is raised and lowered in the pressure relief seat 91 to adjust the activity space of the coolant in the pipeline, thereby adjusting the pressure of the coolant. A second spring 94 is connected to the bottom of the piston plate 93 to support the piston plate 93 to move up and reset. An exhaust hole 95 is provided through the side wall of the pressure relief seat 91 below the second spring 94. When the piston plate 93 moves downward in the pressure relief seat 91, the air inside the pressure relief seat 91 is squeezed. The exhaust hole 95 is used for gas discharge to avoid air blockage caused by the downward movement of the piston plate 93.

[0030] Furthermore, the two sides of the liquid channel 92 are respectively connected to the first liquid outlet pipe 8 and the second liquid outlet pipe 10, and the middle part of the liquid channel 92 is connected to the inner cavity of the pressure relief seat 91. When the car is driving normally, the coolant circulates from the first liquid outlet pipe 8 through the liquid channel 92 and flows into the second liquid outlet pipe 10, wherein the coolant in the water bag 5 circulates. On the one hand, the circulating coolant is used for heat exchange in the radiator body 1 and for collision buffering in the water bag 5. On the other hand, the heat transferred to the water bag 5 from the bottom of the radiator body 1 is taken out in time to avoid the high temperature environment affecting the service life of the water bag 5.

[0031] Furthermore, the upper and lower ends of the second spring 94 are connected to the piston plate 93 and the inner wall of the pressure relief seat 91 respectively. When the second spring 94 is in a normal stretched state, the upper surface of the piston plate 93 is flush with the bottom of the liquid passage 92. In actual use, the supporting force of the second spring 94 on the piston plate 93 must be balanced with the pressure of the coolant during normal circulation. That is, the piston plate 93 will not fall when the coolant circulates normally. Once the lower cover 2 collides with the water bag 5 and pushes it up, the pressure in the water bag 5 increases sharply, pushing the coolant out of the first outlet pipe 8. The coolant flows into the liquid passage 92, and the pressure of the coolant pushes the piston plate 93 downward in the pressure relief seat 91. The second spring 94 is compressed, causing the coolant to flow into the pressure relief seat 91, reducing the pressure of the coolant. The air in the pressure relief seat 91 is discharged from the exhaust hole 95. After the collision, the inside of the water bag 5 is in a negative pressure state, and the rebound force of the second spring 94 pushes the piston plate 93 upward. The piston plate 93 pushes the coolant back to achieve the effect of relieving pressure on the water bag 5 during the buffering process. The inner cavity of the pressure relief seat 91 is connected to the external environment through the exhaust hole 95.

[0032] The method of using this embodiment is as follows: when the user actually uses the radiator body 1 to dissipate heat for a new energy vehicle, first fix the water bag 5 on the upper surface of the lower cover 2, then insert the lower cover 2 and the connecting edge 3 into the interior of the radiator body 1, then place the mounting frame 4 at the bottom of the connecting edge 3, and make the fixing column 41 pass through the connecting edge 3 through the slide groove 31, and then make the fixing column 41 pass through the connecting edge 3 and then pass through the first spring 44 and insert into the slot 101, then insert the mounting bolt 45 from the bottom of the mounting frame 4, so that the mounting bolt 45 passes through the second through hole 43, the center hole 42 and the first through hole 102 in sequence and extends from the top of the radiator body 1, and fix the radiator body. 1. The lower cover 2 and the mounting frame 4 are combined and connected to the battery pack at the top by the mounting bolts 45 to complete the synchronous installation. When the battery module is in working state, the heat on the battery module is conducted away by the radiator body 1. The cooling system in the car passes the coolant into the first liquid inlet pipe 51 through the liquid pump. The coolant passes into the water bag 5 through the first liquid inlet pipe 51. The coolant flows in the water bag 5 to take out a small amount of heat on the water bag 5. Then the coolant passes into the coolant flow groove 6 of the radiator body 1 from the second liquid inlet pipe 7 through the connecting pipe 52. The coolant circulates in the coolant flow groove 6 to exchange heat with the radiator body 1, and a large amount of heat on the radiator body 1 is removed. The heat is brought out, and the coolant carries the heat into the liquid passage 92 from the first liquid outlet pipe 8, and then flows back to the automobile cooling system from the second liquid outlet pipe 10. When the new energy vehicle collides with the road surface during driving, the lower cover 2 is subjected to an upward thrust, and the lower cover 2 drives the connecting edge 3 to move upward in the radiator body 1, so that the connecting edge 3 moves upward relative to the fixed column 41 to squeeze the first spring 44. The compression of the first spring 44 performs a preliminary buffering of the collision, reducing the impact of the collision of the lower cover 2 on the radiator body 1. When the lower cover 2 moves upward and drives the water bag 5 to contact the radiator body 1, the water bag 5 performs a secondary buffering of the collision to prevent the radiator body 1 from being hit by the collision. The water bag 5 is deformed, broken or even leaks when it contacts the radiator body 1 for buffering. The pressure in the inner cavity of the water bag 5 increases sharply, pushing the internal coolant to quickly enter the coolant circulation groove 6 from the connecting pipe 52. The coolant then flows into the liquid channel 92 from the first liquid outlet pipe 8. The pressure of the coolant pushes the piston plate 93 down in the pressure relief seat 91. The second spring 94 is compressed to make the coolant flow into the pressure relief seat 91, reducing the pressure of the coolant. The air in the pressure relief seat 91 is discharged from the exhaust hole 95. After the collision, the inside of the water bag 5 is in a negative pressure state, and the rebound force of the second spring 94 pushes the piston plate 93 up, and the piston plate 93 pushes the coolant back.

[0033] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalent features for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
