Description

Technical Field

[0001] This utility model belongs to the field of thermal management system testing devices, and specifically relates to a comprehensive performance testing device for the thermal management system of new energy vehicles. Background Technology

[0002] The automotive thermal management system is a core device used to regulate the temperature of various vehicle components. It consists of components such as an electric compressor, condenser, PTC heater, plate heat exchanger, water pump, pressure and temperature sensors, expansion tank, expansion valve, water valve, water temperature sensor, and controller. Its applications cover the management of power batteries, engine cooling, and air conditioning systems in new energy vehicles. To ensure the safe use of new energy vehicles, it is necessary to conduct temperature tests on their thermal management systems. However, in the current technology, the testing equipment simply simulates the ambient temperature and humidity control of the vehicle parked in the test chamber, and then tests the operating status of the thermal management system under various temperature and humidity environments. The testing is simple, but the comprehensive testing performance is insufficient. It cannot effectively guarantee that the operating status of the thermal management system under driving conditions and sunlight can be effectively tested, which can easily lead to oversights in the testing.

This addresses the problem that existing technologies simply simulate the environmental temperature and humidity control of vehicles parked in a test chamber, and then test the operating status of the vehicle's thermal management system under various temperature and humidity conditions. While the testing is simple, the comprehensive testing performance is insufficient, and it cannot effectively guarantee that the operating status of the thermal management system of the vehicle under conditions such as driving and lighting can be effectively tested, which can easily lead to oversights in the testing.

[0005] (II) Technical Solution

[0006] This utility model is achieved through the following technical solution: This utility model proposes a comprehensive performance test device for the thermal management system of new energy vehicles, the structure of which includes a test chamber;

[0007] It also includes temperature and humidity regulating pipes, track beams, exhaust vents, a gantry crane, a solar simulator, an electrical control cover, a lifting platform, and rollers. A track beam is fixed to the upper side of the internal side wall of the test chamber, and a gantry crane is mounted on the track beam. The solar simulator is suspended from the bottom of the gantry crane. Temperature and humidity regulating pipes are also installed on the internal side wall of the test chamber, with the top of the pipes lower than the solar simulator. These pipes are used for temperature and humidity regulation within the test chamber. An exhaust vent is located on the top of the test chamber. The lifting platform is embedded in the center of the test chamber's base plate and is in a retracted state. The top of the rollers is flush with the top of the test chamber floor. The rollers are arranged in two rows, with each roller's surface parallel to the others. There is a gap between each roller in the row, which is smaller than the wheel diameter. The two rows of rollers are arranged parallel to each other on both sides of the lifting platform. The top of the two rows of rollers penetrates the top of the test chamber floor. The lifting platform is used to lift the vehicle, and the rollers are used to support the wheels. The top of the rollers is lower than the top of the test chamber floor. The electrically controlled cover is located on the test chamber floor and is used to cover the top of the rollers.

[0008] Furthermore, the rolling direction of both rows of rollers is consistent with the direction in which the vehicle enters and exits the test chamber.

[0009] Furthermore, the temperature and humidity regulating tube includes a temperature control tube and a humidity control tube, which are evenly and alternately arranged on the inner side wall of the test chamber.

[0013] Furthermore, the heat exchange hole is a triangular cross-section groove, and the heat exchange hole is connected to the heat exchange pipe.

[0014] Furthermore, it also includes a power source, which is used for the electronically controlled opening and closing of the cover plate.

[0015] Furthermore, the top of the electrically controlled cover plate is flush with or lower than the top of the bottom plate of the test chamber, and the bottom of the electrically controlled cover plate is connected to the roller.

[0016] Furthermore, the solar simulator is a metal halide lamp, a xenon lamp, an LED lamp, or any other solar simulator in the prior art.

[0017] (III) Beneficial Effects

[0018] One of the above technical solutions has the following advantages or beneficial effects:

[0019] Temperature and humidity regulating pipes are installed on the side walls of the test chamber to regulate the temperature and humidity of the test. Combined with a solar simulator mounted on the ceiling of the test chamber via a gantry crane, the device can simulate sunlight from different directions by moving the gantry crane, ensuring that the vehicle's thermal management system operates as required under real-world lighting conditions. Simultaneously, the test chamber's lifting platform can lift the vehicle after it reaches a fixed area, then open the electrically controlled cover and lower the vehicle, placing it in a roller-supported state. At this point, the rotation of the vehicle's wheels, along with the airflow from the temperature and humidity regulating pipes, simulates the vehicle's thermal management system operating in a moving environment. This achieves a more comprehensive testing function, making the testing of the vehicle's thermal management system more thorough and increasing safety for subsequent use. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0027] Example 1:

[0028] This utility model provides a comprehensive performance testing device for the thermal management system of a new energy vehicle: its structure includes a test chamber 1;

[0029] It also includes a temperature and humidity regulating pipe 2, a track beam 3, an exhaust port 4, a gantry 5, a solar simulator 6, an electrical control cover plate 7, a lifting platform 8, and a roller 11. The track beam 3 is fixed to the upper side of the internal side wall of the test chamber 1. The gantry 5 is mounted on the track beam 3, and the solar simulator 6 is suspended from the bottom of the gantry 5. The temperature and humidity regulating pipe 2 is also mounted on the internal side wall of the test chamber 1. The top of the temperature and humidity regulating pipe 2 is lower than the solar simulator 6. The temperature and humidity regulating pipe 2 is used for temperature and humidity regulation within the test chamber 1. The exhaust port 4 is located at the top of the test chamber 1. The lifting platform 8 is embedded in the center of the base plate of the test chamber 1 and is retracted. The top of the rollers 11 is flush with the top of the bottom plate of the test chamber 1. The rollers 11 are arranged in two rows, and the surfaces of the rollers 11 in the rows are parallel to each other. There is a gap between the rollers 11 in the rows, and the gap is smaller than the diameter of the wheel. The two rows of rollers 11 are arranged parallel to each other on both sides of the lifting platform 8. The top of the two rows of rollers 11 penetrates the top of the bottom plate of the test chamber 1. The lifting platform 8 is used to lift the vehicle, and the rollers 11 are used to support the wheels. The top of the rollers 11 is lower than the top of the bottom plate of the test chamber 1. The electrically controlled cover 7 is provided on the bottom plate of the test chamber 1 and is used to cover the top of the rollers 11.

[0030] Among them, lifting platform 8 is an electrically controlled lifting platform.

[0031] In one embodiment, the rolling direction of both rows of rollers 11 is consistent with the direction in which the vehicle enters and exits the test chamber 1, so that the vehicle can directly walk to the location of the rollers 11.

[0032] In one embodiment, a power source 10 is also included, which is used for the opening and closing of the electronically controlled cover 7.

[0033] In one embodiment, the top of the electrically controlled cover 7 is flush with or lower than the top of the bottom plate of the test chamber 1, and the bottom of the electrically controlled cover 7 is connected to the roller 11.

[0034] In one embodiment, the solar simulator 6 is a metal halide lamp.

[0035] In use, sensors are installed at the vehicle detection location for monitoring. The vehicle can then be driven into test chamber 1 through its door. To facilitate vehicle entry, a pit is pre-set in the test chamber 1 area, with the height of the test chamber 1's base plate, allowing the bottom of test chamber 1 to be embedded within the pit. After the vehicle enters test chamber 1, the door is closed. The temperature and humidity inside test chamber 1 are adjusted and controlled using temperature and humidity control pipe 2 to meet the test conditions for testing the vehicle's thermal management system operation. This allows for testing the vehicle's thermal management system status under different temperature and humidity conditions. During the test, as needed, the solar simulator 6 can be moved to a suitable position using a gantry crane 5 to simulate sunlight, testing the vehicle's thermal management system status under different sunlight conditions. Simultaneously, the vehicle is driven into the designated location within test chamber 1. Then, the lifting platform 8 can be controlled to lift the vehicle off the floor of the test chamber 1. Then, the electrically controlled cover 7 can be opened and the lifting platform 8 can be lowered. As the electrically controlled cover 7 is open, the lowered vehicle tires will contact and support the rollers 11 and fall between two adjacent rollers 11. Since the wheels are supported by the rollers 11 at both ends, when the vehicle starts to move, the wheels will only rotate between the rollers, that is, the vehicle is in a stationary state. With the air blowing from the temperature and humidity regulating pipe 2, the operating state of the vehicle's thermal management system in the driving environment can be simulated, realizing a more comprehensive test function, making the test of the vehicle's thermal management system operating state more comprehensive, increasing the safety of subsequent use, avoiding the situation of incomplete single and static simulation tests, and the structure is simple and clear, easy to operate and use.

[0036] Example 2:

[0037] Compared to Embodiment 1, the temperature and humidity regulating tube 2 in this embodiment includes a temperature control tube and a humidity control tube. The temperature control tube and the humidity control tube are evenly and alternately arranged on the inner side wall of the test chamber 1. The independently arranged temperature control tube and humidity control tube make it easier for the device to control the temperature and humidity separately. The rest of the structure and effect remain unchanged.

[0038] Example 3:

[0039] Compared to the previous embodiments, this embodiment also includes a heat exchange pipe 9, which is used for heat exchange and temperature control of the bottom plate and roller 11 of the test chamber 1.

[0040] The roller 11 includes an outer protective layer 1101, heat exchange holes 1102, a heat exchange layer 1103, a bearing 1104, and a shaft 1105. The shaft 1105 is assembled inside the bottom plate of the test chamber 1. The heat exchange layer 1103 is sleeved on the shaft 1105 through the bearing 1104. The heat exchange layer 1103 has through heat exchange holes 1102. The outer protective layer 1101 is fixedly covered on the outside of the heat exchange layer 1103. The heat exchange layer 1103 is used to exchange heat with the medium flowing in the heat exchange holes 1102 and then conduct it to the outer protective layer 1101.

[0041] The heat exchange layer 1103 is made of aluminum alloy, and the outer protective layer 1101 is made of stainless steel.

[0042] In use, the roller 11 features an outer protective layer 1101 and a heat exchange layer 1103 made of different materials, as well as a triangular cross-section heat exchange hole 1102 penetrating the heat exchange layer 1103. Combined with the ventilation or liquid heat exchange through the heat exchange pipe 9, the roller 11 can better perform heat exchange and temperature regulation while ensuring structural stability. Combined with the heat exchange pipe 9 for heat exchange of the bottom plate of the test chamber 1, the device can simulate the operation of the thermal management system of a vehicle under different ground temperatures, further increasing the comprehensiveness of the test. The rest of the structure and effects remain unchanged.
