Embodiment 1

[0040] Such as figure 1 , Figure 5 and Figure 6 As shown, a thermal management system for electric vehicles based on dual heaters, including a plate 1, a fitting frame 2, a water heating heater 3, a water pump 4, and a water temperature output pipeline 5, and four sets of them are installed on the top of the plate 1 in a square arrangement. chimera box 2;

[0041] Specifically, the plate 1 provides sufficient space for the installation of the water heater 3 and the fuel heater 6, and the fitting frame 2 can facilitate the insertion of the fixed plate 12, and then facilitate the heating of the water heater 3 and the fuel oil welded with the fixed plate 12. The heater 6 is placed on the top of the fitting frame 2, and can effectively prevent the two sets of heaters from being out of contact with the fitting frame 2 during the running of the vehicle.

[0042] Among them, the tops of two groups of fitting frames 2 arranged in front and back are installed with plumbing heaters...

Embodiment 2

[0047] Such as figure 2 As shown, the inner wall of the fitting frame 2 is equipped with a rubber cushion frame 10, the outer wall of the rubber cushion frame 10 is provided with a groove 11, and the bottoms of the water heating heater 3 and the fuel heater 6 are equipped with two sets of fixing plates arranged in front and back. 12, and the front wall and rear wall of the fixed plate 12 are all attached to the inner wall of the rubber pad frame 10, the front and back of the fixed plate 12 are equipped with clips 13, and the outer wall of the clip 13 is attached to the inner wall of the groove 11 combine.

[0048] Specifically, the rubber cushion frame 10 has a certain degree of elasticity, and when it is squeezed, it can shrink inward to change its overall thickness. When the fixing plate 12 is inserted into the interior of the fitting frame 2, the rubber cushion frame 10 will be squeezed. Press inwardly to shrink to facilitate the engagement of the fixed plate 12. When the...

Embodiment 3

[0050] Such as figure 1 , image 3 , Figure 7 and Figure 8 As shown, a vent pipe 14 is installed on one side of the tee pipe 9, an electronic valve 15 is installed on the top of the vent pipe 14, and a battery vent return pipe 16 is installed at one end of the vent pipe 14, and the battery vent return pipe A battery box 17 is installed on the inner wall of the road 16, and the battery box 17 is located in front of the water heating heater 3.

[0051] The bottom wall of the battery box 17 is evenly equipped with multiple groups of battery blocks 18, the outer walls of both sides of the battery box 17 are equipped with temperature sensors 19, and the outer surface of the battery box 17 is equipped with a water temperature returning pipeline 20, and the water temperature returning pipeline 20 is located on the top of the battery ventilation return pipeline 16, a water guide pipe is installed on one side of the water temperature return pipeline 20, an electronic valve 2 21 is...

Abstract

The invention discloses an electric vehicle thermal management system based on double heater. The system comprises a flat plate, embedding frames, water heating heaters, water pumps and water temperature output pipelines, wherein the top of the flat plate is provided with the embedding frame which is arranged in a square shape; the water heating heaters are installed at the top of two sets of embedding frames arranged front and back, fuel heaters are installed at the top of the other two sets of embedding frames arranged front and back, the water pumps are installed at the output ends of the water heating heaters, the water temperature output pipelines are installed at the output ends of the water pumps, and a water inlet pipeline is installed at the input end of each water heating heater; and a connecting pipe is installed at the output end of the fuel oil heater, and an air extracting pump is installed on the front surface of the connecting pipe. The two sets of different heaters can optimize the rate, the heaters are installed in an inserted mode in the assembling process and are convenient to disassemble, the battery system has a temperature monitoring function, temperature increasing and decreasing of the battery are more practical, and the device can absorb vibration and reduce impact on the heaters.

Description

technical field [0001] The invention relates to the technical field of thermal management, in particular to a dual-heater-based electric vehicle thermal management system. Background technique [0002] With the advancement of modern technology, electric vehicles are gradually popularized. They have the function of saving energy and reducing exhaust emissions, which can effectively protect the environment. In the promotion process of electric vehicles, the mileage, charging time and safety of use are mainly restricted by the characteristics of power batteries. The characteristics of lithium-ion power batteries are significantly affected by the ambient temperature, especially in low-temperature environments, where the available energy and power are severely attenuated, and long-term use in low-temperature environments will accelerate the aging of power batteries and shorten their service life. The capacity and working voltage of commonly used lithium-ion power batteries for e...
