Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a cooling device for an automotive thermal management system. Background Technology

[0002] With the development of automotive technology, the design of cooling systems has become increasingly complex, such as electronically controlled cooling systems and integrated thermal management designs, enabling vehicles to maintain efficient operation under different conditions. Preventing overheating is not only related to engine performance but also to driving safety. Overheating may lead to engine failure or even accidents, so the reliability of the cooling device is crucial. By using a cooling device, the engine can be kept within its optimal operating temperature range to prevent overheating, thereby improving combustion efficiency and power output. It not only affects engine temperature but is also closely related to the vehicle's air conditioning and internal temperature control system, ensuring passenger comfort during the journey.

[0003] The automotive thermal management system includes a cooling system and an air conditioning system, which are interconnected. When setting up a test bench to test the cooling system, since the air conditioning system has two schemes, heat pump and non-heat pump, it is usually necessary to set up two test benches to meet the needs of different schemes, which is time and money costly. Furthermore, the fan blades in the air-cooled condenser of the existing automotive thermal management system are fixed. The fixed angle of the fan blades may cause uneven airflow distribution inside the condenser, affecting the heat exchange effect of the refrigerant and thus reducing the condensing efficiency. It is impossible to optimize the airflow according to different operating conditions (such as changes in ambient temperature), resulting in a decrease in heat exchange efficiency and affecting system performance.

[0004] Therefore, there is an urgent need to provide a cooling device for automotive thermal management systems to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cooling device for an automotive thermal management system.

[0006] To solve the above-mentioned technical problems, the present invention provides a cooling device for an automotive thermal management system, comprising a cooling system electrically connected to a water-cooled condenser and a plate heat exchanger, the plate heat exchanger electrically connected to a compressor and an expansion valve, the compressor electrically connected to a first shut-off valve and a second shut-off valve, the second shut-off valve electrically connected to the water-cooled condenser, the first shut-off valve electrically connected to an air-cooled condenser, and the air-cooled condenser electrically connected to a one-way valve, the one-way valve being electrically connected to the water-cooled condenser and the expansion valve.

[0007] The above technical solutions can reduce development cycles and experimental costs, avoid building different test platforms multiple times, and save resources.

[0008] The present invention is further configured such that: the air-cooled condenser includes a condenser body, the condenser body has a hollow structure inside, a grid is installed on one side of the condenser body, a fixing frame is fixedly connected to one side of the condenser body, a plurality of heat sinks are installed in the fixing frame, and a cross fixing plate is fixedly connected to the inner wall of the condenser body.

[0009] The present invention is further configured such that: a first bevel gear is rotatably connected to one side of the cross-shaped fixing plate; a second bevel gear is driven by the first bevel gear; a fixing rod is fixedly connected to the second bevel gear; the fixing rod is rotatably connected to the inner wall of the condenser body; a motor is installed on the top surface of the condenser body; the output end of the motor is rotatably connected through the condenser body; and the through end of the motor is fixedly connected to the fixing rod.

[0010] The above technical solutions can flexibly respond to changes in ambient temperature and load fluctuations, improve the system's adaptability, and ensure good cooling performance under various working conditions.

[0011] The present invention is further configured such that: a drive rod is rotatably connected through the side of the cross fixing plate away from the first bevel gear; the through end of the drive rod is fixedly connected to the first bevel gear; the other end of the drive rod is rotatably connected to the fence; limit strips are welded to the outer wall of the drive rod near both sides of the cross fixing plate; and a rectangular plate is slidably connected through the drive rod and the limit strips.

[0012] The present invention is further configured such that: a plurality of hydraulic rods are provided on one side of the rectangular plate, the plurality of hydraulic rods are arranged symmetrically in a circle, one end of the hydraulic rod is fixedly connected to the drive rod, and the telescopic end of the hydraulic rod is fixedly connected to the rectangular plate.

[0013] By using the above technical solutions, optimizing airflow and reducing energy consumption can reduce system pressure and burden, extend the service life of air-cooled condensers and their components, and reduce maintenance costs.

[0014] The present invention is further configured such that: a plurality of first connecting rods are fixedly connected to one corner of the rectangular plate; a connecting plate is rotatably connected to the other end of the first connecting rod; a second connecting rod is rotatably connected to the other end of the connecting plate; a fan blade is rotatably connected to the other end of the second connecting rod; and the fan blade is rotatably connected to the drive rod.

[0015] The above technical solutions enable the required airflow to be achieved at lower speeds, reducing energy consumption, thereby improving overall energy efficiency and reducing energy waste.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a motor to drive a fixed rod to rotate, and a second bevel gear to rotate synchronously, causing the first bevel gear to rotate. This, in turn, drives the components inside the drive rod and hydraulic rod to rotate synchronously, causing the fan blades to rotate, disturbing the airflow, and generating airflow to achieve heat dissipation. When the heat exchange efficiency is improved, the hydraulic rod drives the rectangular plate to move in the linear direction of the drive rod and the limit bar, causing the connecting plate to rotate relative to the first connecting rod. At the same time, the second connecting rod rotates relative to the connecting plate, which in turn pulls the fan blades to rotate, creating an angle difference. This achieves the best heat exchange effect under different load and temperature conditions, enhances condensation capacity, and improves system performance.

[0018] 2. This utility model, by setting up a cooling system test bench scheme that can directly switch between heat pump and non-heat pump schemes, can effectively save time and money. Furthermore, it can easily compare the performance of heat pump and non-heat pump schemes under the same conditions, helping the R&D team to evaluate their respective advantages and disadvantages, thereby making more scientific design decisions.

[0027] Please see Figures 1-6 A cooling device for an automotive thermal management system includes a cooling system 1. The cooling system 1 is electrically connected to a water-cooled condenser 6 and a plate heat exchanger 2. The plate heat exchanger 2 is electrically connected to a compressor 5 and an expansion valve 7. The compressor 5 is electrically connected to a first shut-off valve 3 and a second shut-off valve 4. The second shut-off valve 4 is electrically connected to the water-cooled condenser 6. The first shut-off valve 3 is electrically connected to an air-cooled condenser 8. The air-cooled condenser 8 includes a condenser body 81. The condenser body 81 has a hollow internal structure, and a grille 82 is installed on one side of the condenser body 81. 1. A fixed bracket 83 is fixedly connected to one side. Several heat sinks 85 are installed inside the fixed bracket 83. A cross-shaped fixing plate 86 is fixedly connected to the inner wall of the condenser body 81. A drive rod 810 is rotatably connected through the cross-shaped fixing plate 86 on the side away from the first bevel gear 87. The through end of the drive rod 810 is fixedly connected to the first bevel gear 87, and the other end of the drive rod 810 is rotatably connected to the fence 82. Limiting strips 816 are welded to both sides of the outer wall of the drive rod 810 near the cross-shaped fixing plate 86. A rectangular plate 811 is slidably connected through the drive rod 810 and the limiting strips 816. Several first connecting rods 812 are fixedly connected to one corner of the rectangular plate 811. A connecting plate 813 is rotatably connected to the other end of each first connecting rod 812. A second connecting rod 814 is rotatably connected to the other end of the connecting plate 813. A fan blade 815 is rotatably connected to the other end of the second connecting rod 814. The fan blade 815 is rotatably connected to the drive rod 810. Several hydraulic rods 89 are arranged symmetrically in a circle on one side of the rectangular plate 811. One end of each hydraulic rod 89 is fixedly connected to the drive rod 810, and the telescopic end of the hydraulic rod 89 is fixed to the rectangular plate 811. The connection includes a first bevel gear 87 rotatably connected to one side of the cross-shaped fixing plate 86, a second bevel gear 88 being driven by the first bevel gear 87, a fixing rod 817 being fixedly connected to the second bevel gear 88, and the fixing rod 817 being rotatably connected to the inner wall of the condenser body 81. A motor 84 is mounted on the top surface of the condenser body 81, and the output end of the motor 84 is rotatably connected to the condenser body 81 through it. The through end of the motor 84 is fixedly connected to the fixing rod 817. The air-cooled condenser 8 is electrically connected to a one-way valve 9, and the one-way valve 9 is electrically connected to the water-cooled condenser 6 and the expansion valve 7.

[0028] When this utility model is in use, if the cooling system 1 needs to be matched with a non-heat pump system for testing and verification, the second shut-off valve 4 is closed, the first shut-off valve 3 is opened, and the compressor 5 is turned on. The refrigerant of the air conditioning system circulates along the circuit of compressor 5, first shut-off valve 3, air-cooled condenser 8, one-way valve 9, expansion valve 7, plate heat exchanger 2, and compressor 5. At this time, the air-cooled condenser 8 releases the heat of the high-temperature refrigerant flowing out of the compressor 5 into the air for heat dissipation, while the plate heat exchanger 2 uses the low-temperature refrigerant flowing out of the expansion valve 7 to absorb the heat of the water in the cooling system 1 for cooling.

[0029] When the cooling system 1 needs to be matched with the heat pump system for testing and verification, the second shut-off valve 4 opens and the first shut-off valve 3 closes. After the compressor 5 is turned on, the refrigerant of the air conditioning system circulates along the circuit of compressor 5, second shut-off valve 4, water-cooled condenser 6, expansion valve 7, plate heat exchanger 2, and compressor 5. The one-way valve 9 can prevent the refrigerant from the water-cooled condenser 6 from flowing into the air-cooled condenser 8. At this time, the water-cooled condenser 6 releases the heat of the high-temperature refrigerant flowing out of the compressor 5 into the water of the cooling system 1 for heating the passenger compartment or battery, while the plate heat exchanger 2 uses the low-temperature refrigerant flowing out of the expansion valve 7 to absorb the heat of the water in the cooling system 1.

[0030] Furthermore, when the air-cooled condenser 8 is running, the motor 84 drives the fixed rod 817 to rotate, and the second bevel gear 88 rotates synchronously, causing the first bevel gear 87 to rotate, which in turn drives the components in the drive rod 810 and hydraulic rod 89 to rotate synchronously, thereby causing the fan blades 815 to rotate, disturbing the airflow and generating air flow, thereby achieving heat dissipation. When the heat exchange efficiency is improved, the hydraulic rod 89 drives the rectangular plate 811 to move in the linear direction of the drive rod 810 and the limiting strip 816, thereby causing the connecting plate 813 to rotate relative to the first connecting rod 812, and at the same time the second connecting rod 814 to rotate relative to the connecting plate 813, thereby pulling the fan blades 815 to rotate, creating an angle difference, optimizing the airflow distribution, improving heat exchange efficiency, and ensuring sufficient condensation of the refrigerant.
