Description

Technical Field

[0001] This invention relates to the field of battery cooling technology, specifically to a battery cooler with a high-strength support structure. Background Technology

[0002] A battery cooler is a device used in electric vehicles to cool the battery. It uses coolant as a medium; the coolant flows through flat tubes between the battery cells, carrying away heat from the cells. The hot coolant then enters the battery cooler for further cooling before returning to the battery to achieve cooling. Current battery coolers are typically plate-type structures composed of multiple layers of thin metal plates. They contain refrigerant and coolant channels and rely on the vehicle's air conditioning system to cool the coolant with a low-temperature refrigerant. Since cooling is solely dependent on the low-temperature refrigerant generated by the air conditioning system, heat dissipation depends entirely on the operation of the air conditioning system's compressor and condenser. However, the compressor consumes electricity, and there are no other auxiliary cooling methods to reduce power consumption. Furthermore, the outer casing of current battery coolers lacks strong support protection, making them susceptible to coolant leakage from impacts with gravel. Summary of the Invention

[0003] The purpose of this invention is to provide a battery cooler with a high-strength support structure to solve the problem of insufficient energy efficiency of battery coolers mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a battery cooler with a high-strength support structure, comprising a coolant shell and a refrigerant bend passing through the interior of the coolant shell, wherein the battery coolant flows inside the coolant shell, and when the refrigerant flows through the refrigerant bend, the battery temperature decreases by cooling the battery coolant. The upper and lower surfaces of the coolant housing are symmetrically equipped with heat-conducting fins. Dynamic air shrouds are respectively installed above and below the coolant housing. The surface of the dynamic air shroud has through-scraper grooves, through which the heat-conducting fins pass and extend into the interior of the dynamic air shroud. During vehicle operation, the airflow is directed by the vehicle's airflow design to pass through the interior of the dynamic air shroud, and the heat-conducting fins cool the coolant inside the coolant housing. When the air temperature inside the dynamic air shroud is higher than the coolant temperature, the dynamic air shroud moves away from the coolant housing, causing the heat-conducting fins to move out of the dynamic air shroud.

[0005] The surface of the dynamic shroud is fixedly provided with side wing plates, and a separation push cylinder is fixedly installed on the side wing plates. The side wing plates on the same side are connected to each other by a closing tension spring. The separation push cylinder drives the dynamic shroud to move away from the coolant shell, and the closing tension spring drives the dynamic shroud to move towards the coolant shell.

[0006] The coolant housing is provided with connecting air plates at both ends. An end-side support plate is provided between the connecting air plate and the coolant housing. The end-side support plate fixes the coolant housing and the connecting air plate relatively. A path-adapting hose is connected to the connecting air plate. The other end of the path-adapting hose is connected to the dynamic shroud. The path-adapting hose can be bent and moved to adapt to the movement and adjustment of the dynamic shroud.

[0007] The separation push cylinder has a piston part inside, which is in sealed contact with the inner wall surface of the separation push cylinder. A bidirectional tube shaft is fixedly installed on the piston part, and a connecting shaft seat is fixedly installed between the bidirectional tube shaft and the coolant shell.

[0008] A gas compression chamber is provided at one end of the bidirectional tube shaft near the piston. A pneumatic control pipe is connected to the outside of the bidirectional tube shaft. The pneumatic control pipe is connected to the inner cavity of the separation push cylinder through the inner cavity of the bidirectional tube shaft. When positive pressure gas is input through the pneumatic control pipe, the dynamic fan shroud can move away from the coolant shell.

[0009] The side wing plate is provided with a collision lock groove and a pressure storage resistance groove, and the coolant shell is provided with a status back plate.

[0010] A locking groove connecting rod is fixedly installed on the status back plate. The locking groove connecting rod corresponds to the position of the collision locking groove, and a collision end is fixedly installed at the end of the locking groove connecting rod.

[0011] A resistance rod is fixedly installed on the state back plate. A triangular protrusion is fixedly installed on the surface of the resistance rod. An avoidance groove is opened in the resistance rod. The resistance rod corresponds to the position of the pressure storage resistance groove.

[0012] A positioning vertical shaft is fixedly installed on the surface of the coolant housing. The positioning vertical shaft passes through the state back plate. A limiting end plate is fixedly installed at the end of the positioning vertical shaft. The state back plate is limited by the limiting end plate. A vertical shaft spring is installed between the state back plate and the coolant housing. The supporting elastic force of the vertical shaft spring makes the state back plate make limiting contact with the limiting end plate. At this time, the locking groove connecting rod is outside the collision locking groove, and the resistance rod is outside the pressure accumulating resistance groove.

[0013] An electromagnet module is fixedly installed on the surface of the coolant shell. When the electromagnet module is energized and generates magnetic force, it can attract the state back plate to move against the supporting elastic force of the vertical axis spring, so that the locking groove connecting rod moves into the collision locking groove and the resistance rod moves into the pressure storage resistance groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention's battery cooler guides airflow during vehicle operation into a dynamic shroud to cool the battery coolant. When the battery generates low heat, cooling is achieved without needing to activate the air conditioning system's refrigerant cooling, thus reducing power consumption. When the battery generates high heat, the coolant flowing through a refrigerant bend in the refrigerant pipe enables simultaneous cooling of both the airflow and the refrigerant, improving cooling efficiency. Furthermore, when the ambient airflow temperature is detected to be higher than the coolant temperature, the dynamic shroud can be adjusted to reposition the heat-conducting fins, preventing reverse heat conduction and reducing airflow resistance within the shroud, thereby reducing wind resistance during driving.

[0015] Furthermore, through the combination of the heat-conducting plates and the scraper grooves, the movement of the dynamic fan shroud can clean the heat-conducting plates, ensuring stable heat dissipation efficiency and reducing maintenance. Simultaneously, in conjunction with the locking rod, resistance rod, and status backplate, it can accelerate and impact-spray dust adhering to the inner surface of the dynamic fan shroud at the scraper grooves, causing it to be blown away with the airflow, thus improving the cleaning effect.

[0016] This invention combines heat-conducting plates and dynamic fan shrouds distributed on the upper and lower sides of the coolant housing to form a high-strength support and protection structure, thereby better protecting the coolant housing and reducing the probability of coolant leakage in the event of impact from gravel or other objects.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 8 This invention provides a battery cooler with a high-strength support structure, including a coolant housing 1 and a refrigerant bend 2. Connecting air plates 9 are respectively provided at both ends of the coolant housing 1. An end-side support plate 901 is provided between the connecting air plate 9 and the coolant housing 1. The surface of the end-side support plate 901 is provided with reinforcing ribs to improve the support strength of the end-side support plate 901. The end-side support plate 901 fixes the coolant housing 1 and the connecting air plate 9 relatively. This invention's battery cooler achieves high-strength support and fixed installation through the end-side support plate 901, keeping the coolant housing 1 fixed to the vehicle body.

[0028] The battery cooler of this invention is used in conjunction with a circulating water pump, an automotive air conditioning system, an expansion tank, etc., to form a complete battery cooling system. The battery coolant flows inside the coolant tank 1, and the circulating water pump drives the coolant flow. The expansion tank is used to replenish the coolant. The automotive air conditioning system includes a compressor and a condenser, etc., and low-temperature refrigerant is circulated into the refrigerant bend 2 through the automotive air conditioning system.

[0029] like Figure 5 As shown, spiral fins 201 are welded to the surface of the refrigerant bend 2. The spiral fins 201 increase the contact area between the refrigerant bend 2 and the coolant, thereby improving the cooling efficiency of the refrigerant bend 2 for the coolant.

[0030] When the refrigerant flows through the refrigerant bend 2, it cools the battery's coolant, causing the battery temperature to drop; for example... Figure 5 As shown, the refrigerant bend 2 has an S-shaped bend, and a flow guide baffle 101 is welded inside the coolant housing 1. The flow guide baffle 101 creates a directional flow channel for the coolant inside the coolant housing 1. The technical effect of the flow guide baffle 101 is to obstruct and limit the flow of coolant inside the coolant housing 1, making the coolant flow more orderly and exhibiting an S-shaped bend corresponding to the refrigerant bend 2. At this time, the coolant can flow along the bending path of the refrigerant bend 2 through the flow channel, increasing the contact time between the coolant and the outer surface of the refrigerant bend 2. Figure 5 As shown, coolant connection pipes 102 are welded and connected at both ends of the coolant housing 1. There are two coolant connection pipes 102 in total. The coolant of the battery flows in through one coolant connection pipe 102 and flows out through the other coolant connection pipe 102.

[0031] Heat-conducting fins 3 are symmetrically arranged on the upper and lower surfaces of the coolant housing 1. Dynamic air shrouds 4 are respectively arranged above and below the coolant housing 1. Temperature sensors are installed in the dynamic air shrouds 4 to detect the temperature of the airflow passing through them. A through-scraper groove 5 is opened through the surface of the dynamic air shroud 4, and the heat-conducting fins 3 are inserted through the through-scraper groove 5 into the interior of the dynamic air shroud 4. During vehicle operation, the airflow is directed through the interior of the dynamic air shroud 4 by the vehicle's airflow design, and the heat-conducting fins 3 cool the coolant inside the coolant housing 1. When the air temperature inside the dynamic air shroud 4 is higher than the coolant temperature, the dynamic air shroud 4 moves away from the coolant housing 1, causing the heat-conducting fins 3 to move out of the dynamic air shroud 4.

[0032] The surface of the dynamic fan cover 4 is fixedly provided with side wing plates 6, and a separation push cylinder 7 is fixedly installed on the side wing plates 6. The side wing plates 6 on the same side are connected to each other by a closing tension spring 8. The dynamic fan cover 4 is driven to move away from the coolant housing 1 by the separation push cylinder 7, and the dynamic fan cover 4 is driven to move towards the coolant housing 1 by the closing tension spring 8.

[0033] A path-adapting hose 902 is connected to the connecting air panel 9. The other end of the path-adapting hose 902 is connected to the dynamic shroud 4. An air-gathering duct is opened at the front of the vehicle and is connected to the connecting air panel 9 via an air duct. The other end of the connecting air panel 9 is connected to the exhaust duct. This allows airflow to enter the path-adapting hose 902 through the air-gathering duct during vehicle operation, pass through the dynamic shroud 4, and then exit through the path-adapting hose 902 on the other side. The path-adapting hose 902 can bend and move to adapt to the movement and adjustment of the dynamic shroud 4.

[0034] The separator cylinder 7 has a piston section 701 inside, which is in sealed contact with the inner wall surface of the separator cylinder 7. A bidirectional tube shaft 702 is fixedly mounted on the piston section 701, and a connecting shaft seat 704 is fixedly mounted between the bidirectional tube shaft 702 and the coolant housing 1. A gas compression chamber 703 is opened at one end of the bidirectional tube shaft 702 near the piston section 701. An air control pipe 705 is connected to the outside of the bidirectional tube shaft 702. In use, the air control pipe 705 is connected to a small air pump in the vehicle through a solenoid valve.

[0035] The pneumatic control pipe 705 is connected to the inner cavity of the separation push cylinder 7 through the inner cavity of the bidirectional tube shaft 702. When positive pressure gas is input through the pneumatic control pipe 705, the dynamic fan cover 4 can move away from the coolant housing 1.

[0036] When the vehicle battery is in a low-heat state, the airflow passes through the dynamic shroud 4 and exchanges heat with the heat-conducting fins 3 inside the dynamic shroud 4, thereby cooling the coolant housing 1 and carrying away the heat of the coolant inside the coolant housing 1 to cool the battery. At this time, there is no need for the refrigerant bend 2 to cool down, so as to achieve energy saving.

[0037] When the vehicle is traveling at high speed and the battery generates a lot of heat, the refrigerant bend 2 and the heat conduction plate 3 simultaneously cool the coolant to ensure efficient cooling.

[0038] The circulating temperature of the coolant after cooling is typically between 20 and 30 degrees Celsius. In hot environments such as summer, the airflow temperature passing through the dynamic fan shroud 4 may be higher than the coolant temperature, easily causing heat transfer in the opposite direction. This invention addresses this issue... Figure 8 As shown, positive pressure gas is input into the gas control pipe 705. The positive pressure gas enters the interior of the separation push cylinder 7 through the bidirectional pipe shaft 702 and the gas compression chamber 703, driving the separation push cylinder 7 to move axially relative to the bidirectional pipe shaft 702. At this time, the upper and lower sets of dynamic air shrouds 4 will separate and move. The dynamic air shrouds 4 will move away from the coolant shell 1, so that the heat conduction plate 3 will gradually move out of the dynamic air shroud 4 by passing through the scraper groove 5 until the end face of the heat conduction plate 3 is flush with the inner wall surface of the dynamic air shroud 4 and then stops. At this time, when the airflow passes through the dynamic air shroud 4, it will no longer exchange heat with the heat conduction plate 3. The cooling is enhanced by the refrigerant bend pipe 2 in conjunction with the car air conditioning system to achieve the cooling of the coolant.

[0039] The side wing plate 6 has a collision lock groove 601 and a pressure accumulating resistance groove 602. A status back plate 603 is provided on the outside of the coolant shell 1. A lock groove connecting rod 604 is fixedly provided on the status back plate 603. The lock groove connecting rod 604 corresponds to the collision lock groove 601 in position. A collision end 605 is fixedly provided at the end of the lock groove connecting rod 604. A resistance rod 606 is fixedly provided on the status back plate 603. A triangular protrusion 607 is fixedly provided on the surface of the resistance rod 606. An avoidance groove 608 is provided in the resistance rod 606. The resistance rod 606 corresponds to the pressure accumulating resistance groove 602 in position.

[0040] A positioning vertical shaft 609 is fixedly installed on the surface of the coolant housing 1. The positioning vertical shaft 609 passes through the state back plate 603. A limiting end plate 610 is fixedly installed at the end of the positioning vertical shaft 609. The state back plate 603 is limited by the limiting end plate 610. A vertical shaft spring 611 is installed between the state back plate 603 and the coolant housing 1. The supporting elastic force of the vertical shaft spring 611 makes the state back plate 603 contact the limiting end plate 610 in a limited position. At this time, the locking groove connecting rod 604 is outside the collision locking groove 601, and the resistance rod 606 is outside the pressure accumulating resistance groove 602.

[0041] An electromagnet module 612 is fixedly installed on the surface of the coolant housing 1. When the electromagnet module 612 is energized and generates magnetic force, it can attract the state back plate 603 to move against the supporting elastic force of the vertical axis spring 611, so that the locking groove connecting rod 604 moves into the collision locking groove 601 and the resistance rod 606 moves into the pressure accumulating resistance groove 602.

[0042] When the dynamic shroud 4 separates and moves, the path adaptation hose 902 deforms and bends to adapt to the small displacement of the dynamic shroud 4, maintaining airflow. Although the small bending of the path adaptation hose 902 will slightly increase the resistance to airflow, the dense array of heat-conducting plates 3 moving out of the dynamic shroud 4 will further reduce the resistance to airflow through the dynamic shroud 4. Overall, the resistance to airflow through the cooler is still reduced, thereby reducing the wind resistance of the car at this time.

[0043] When it is necessary to control the dynamic fan cover 4 to close and reset towards the coolant housing 1, it is only necessary to control the air control pipe 705 to connect with the atmosphere through the air valve. Under the elastic tension of the closing tension spring 8, the gas in the separation push cylinder 7 is discharged, and the dynamic fan cover 4 automatically closes and resets.

[0044] like Figure 8 As shown, when the dynamic fan shroud 4 moves by separating or closing, it scrapes the surface of the heat-conducting plate 3 by passing through the scraper groove 5 to clean the heat-conducting plate 3. Since the heat-conducting plate 3 is in direct contact with the external airflow passing through the dynamic fan shroud 4 for heat exchange, it is easy for dust to accumulate after long-term use. When the dynamic fan shroud 4 moves, the scraping through the scraper groove 5 can keep the surface of the heat-conducting plate 3 clean and reduce maintenance.

[0045] Regarding the contact between the scraper groove 5 and the heat-conducting plate 3, in the first embodiment, an asbestos strip is embedded on the inner side of the scraper groove 5, and the elastic contact of the asbestos strip automatically adapts to the wear of the heat-conducting plate 3.

[0046] In the second embodiment, an elastic metal sheet is provided on the inner side of the groove 5. The metal sheet is in elastic contact with the heat-conducting sheet 3 and can be automatically replenished when the heat-conducting sheet 3 is worn.

[0047] This invention omits the description of this, ensuring that the scraper 5 and the heat-conducting plate 3 are in close contact and that the heat-conducting plate 3 can work normally when a certain amount of wear occurs.

[0048] With attachment Figure 8 Taking the dynamic hood 4 at the top as an example: when the dynamic hood 4 moves upward, it moves upward relative to the heat-conducting plate 3 through the scraper groove 5. The dust on the surface of the heat-conducting plate 3 accumulates on the lower inner surface of the dynamic hood 4, near the scraper groove 5. The loosely adhered dust is directly discharged with the airflow in the dynamic hood 4.

[0049] Some dust adheres to the inner lower surface of the dynamic wind shroud 4. This invention accelerates the impact and spraying by energizing the electromagnet module 612. When the electromagnet module 612 is energized, the back plate 603 moves towards the electromagnet module 612 through magnetic attraction. At this time, the locking groove connecting rod 604 and the resistance rod 606 move into the collision locking groove 601 and the pressure accumulating resistance groove 602, respectively. Then, positive pressure gas is input into the pneumatic control pipe 705. Initially, the dynamic wind shield 4 moves slightly, causing the triangular protrusion 607 to interfere with the pressure accumulating resistance groove 602. The dynamic wind shield 4 is then restricted and cannot continue to separate and move. As the positive pressure gas continues to be supplied, the gas pressure is compressed and stored inside the gas compression chamber 703 and the separation push cylinder 7. At the same time, the tendency force of the dynamic wind shield 4 to separate and move also increases until the resistance rod 606 deforms and folds inward through the avoidance groove 608, causing the triangular protrusion 607 to disengage from the pressure accumulating resistance groove 602. At this time, the dynamic wind shield 4 is suddenly released. Driven by the accumulated pressure, the dynamic wind shield 4 will accelerate and move.

[0050] In the next stage, the side wing plate 6 and the collision end 605 collide and interfere again. During the acceleration and upward movement of the dynamic wind hood 4, the side wing plate 6 and the collision end 605 collide and interfere, and the dynamic wind hood 4 will suddenly stop moving. The dust adhering to the lower inner surface of the dynamic wind hood 4 continues to move upward under the inertial force, thereby breaking free from adhesion and completing the scattering. It is discharged with the airflow in the dynamic wind hood 4, achieving further efficient cleaning.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
