Description

Technical Field

[0001] This invention relates to the field of power conversion technology, and in particular to a temperature monitoring and alarm device for bidirectional converters used in lithium iron phosphate battery equipment. Background Technology

[0002] A bidirectional converter is a DC / DC converter that can adjust the bidirectional energy transmission as needed. It is mainly used in the field of electric vehicles. In order to monitor the real-time status of the bidirectional converter and prevent its temperature from getting too high, a temperature monitoring and alarm device is needed.

[0003] Currently, traditional temperature monitoring and alarm devices are usually directly fixed to the housing of the converter and monitor the temperature through temperature sensors. However, since bidirectional converters used in electric vehicles are usually installed on the vehicle body, they are susceptible to vibrations that could cause the internal monitoring device to fall off, making it difficult to monitor the internal components. Furthermore, because the monitoring device is fixed inside the converter, the converter needs to be disassembled for maintenance, making the replacement and maintenance process complicated and inconvenient for use.

[0045] The specific usage and function of this embodiment: In this invention, during assembly, the exchanger housing 201 is fixed inside the base frame 101. Then, the mounting plate 301 is clipped in front of the two sets of positioning vertical rods 204, so that the torsion block 306 and the clamping plate 307 are inserted into the docking slot 203 during installation. Then, the telescopic locking block 102 is pulled outward, thereby increasing the distance between the telescopic locking block 102 and the base frame 101. Then, the interlocking vertical frame 104 is placed between the telescopic locking block 102 and the base frame 101. Then, the telescopic locking block 102 is released to reset it. Then, the support rod 302 is rotated. The screws cause the mounting plate 301 to move upward under the action of the threads, thereby achieving a tight state. The mounting plate 301 and the telescopic locking block 102 are interlocked under the action of the interlocking vertical frame 104 to maintain stability between them and the exchanger housing 201. Then, the docking side plate 401 is pushed inward, so that it is connected to the mounting plate 301 with screws while being inserted into the docking side hole 202. Then, the plug-in monitoring block 304 is locked inside the docking locking block 303 by the locking block 305, so that the temperature sensor at the bottom extends into the interior of the exchanger housing 201. Finally, the entire device is fixed to the external vehicle body.

[0046] During use, two sets of temperature sensors monitor the temperature at different locations inside the heat exchanger housing 201. When the temperature is too high, an alarm is triggered by an alarm component. At the same time, the temperature sensors send a trigger signal to the control center, which controls the motor to rotate the block 403. During the rotation, the alignment baffle 404 is adjusted within the docking groove 402 by the locking teeth, so that the alignment baffle 404 aligns with the rectangular opening on the docking side plate 401, connecting the inside and outside of the heat exchanger housing 201, thereby assisting the heat exchanger housing 201 in heat dissipation.

[0047] When replacing the temperature sensor, the plug-in monitoring block 304 is twisted, which causes the locking block 305 to adjust the docking lock block 303. During the twisting process, the inclined L-shaped bracket on the locking block 305 is forced to retract through the internal arc groove, thereby releasing the constraint between the docking lock block 303 and the plug-in monitoring block 304. This allows the temperature sensor to be pulled out directly by pulling it out, making it convenient for replacement.
