Description

TECHNICAL FIELD

[0001] The utility model relates to power battery temperature acquisition technical field, specifically a temperature sensor mounting structure. BACKGROUND

[0002] The battery management system (BMS) of electric automobile needs to monitor the temperature of power battery in real time, when the temperature of power battery exceeds the best working temperature interval of battery, the battery management system (BMS) will send instructions to thermal management system (TMS) to cool or heat power battery. And the battery management system (BMS) is according to the battery coolant temperature collected by thermal management system (TMS) to make judgment, therefore needs to install temperature sensor in thermal management system (TMS) to carry out real-time monitoring to coolant temperature.

[0003] Now the temperature acquisition mode of thermal management system (TMS) is mostly to screw temperature sensor on coolant pipe by thread fixing mode, because there is 4-5 kg pressure in coolant system, to guarantee that the connecting place does not leak, needs to smear sealant or wind raw material belt or increase rubber sealing ring on thread. These modes increase assembly workload, and there is the leakage of sealing not strictly caused by human factors;And when temperature sensor needs to be replaced in later period, must first discharge coolant, after temperature sensor is replaced, adds coolant again, finally still needs to carry out system air exhausting work, and the air mixed in cooling system is discharged, adds a lot of work to after-sales service personnel.

Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model.

[0021] Please refer to Figures 1-4 In the embodiments of the utility model, a temperature sensor mounting structure comprises a cooling liquid pipe 1, the cooling liquid pipe 1 is provided with a blind pipe 2, one end of the blind pipe 2 extends into the cooling liquid pipe 1, a spring sheet 3 is mounted in the blind pipe 2, and a temperature sensor 4 is mounted on the spring sheet 3 of the blind pipe 2. The cooling liquid pipe 1 is provided with a round hole, the blind pipe 2 is inserted into the cooling liquid pipe 1 through the round hole, and is fixed by welding after insertion. The spring sheet 3 is made of stainless steel, and the blind pipe 2 is made of stainless steel or red copper. A round hole is first opened on the cooling liquid pipe, a stainless steel blind pipe with an inner diameter of 7*30*0.5T mm is inserted into the cooling liquid pipe, the insertion depth is the radius size of the cooling liquid pipe, the blind pipe is welded on the cooling liquid pipe by welding, a stainless steel spring sheet is mounted in the blind pipe, and a temperature sensor with a diameter of 5*25 is inserted in the red copper pipe. Since the stainless steel blind pipe is pre-welded on the cooling liquid pipe where the temperature needs to be collected, the subsequent production process will not have a complicated threaded installation process and a work of processing a sealed water leakage prevention; moreover, the stainless steel blind pipe adopts a stainless steel welding process, has high pressure resistance, and has no risk of water leakage; in addition, the temperature sensor is mounted in the blind pipe by the stainless steel spring sheet, when the temperature sensor needs to be replaced due to failure in the later period, the temperature sensor can be directly taken out and replaced, without the need to discharge the cooling liquid, so that the maintenance time and cost are greatly reduced. Meanwhile, the stainless steel blind pipe is inserted into the inside of the cooling liquid pipe, and the collected temperature is more accurate.
