Wherein, each group of temperature probes 100 in the at least one group of temperature probes 100 comprises a plurality of closely arranged temperature probes (as shown in temperature probe 1, temperature probe 2, …, and temperature probe N), and the at least one group of temperature probes 100 is used for detecting the temperature of at least one temperature detection point in the carrier fluid. The fixing assembly 200 is used for correspondingly fixing at least one group of temperature probes 100 on at least one temperature detection point of the carrier fluid. The device 10 of the embodiment of the invention can realize the purpose of parallel arrangement, can offset temperature fluctuation, improves the stability of acquired data, improves the accuracy of detection, ensures the reliability of detection, and is simple and easy to realize.
Further, in an embodiment of the present invention, the apparatus 10 of the embodiment of the present invention further includes: and (6) a protective sleeve. Wherein the leads of a plurality of temperature probes in each group of temperature probes are formed in a protective sleeve.

Optionally, in an embodiment of the present invention, the fixing assembly includes a binding wire, so that the temperature probe is sufficiently contacted with the current carrier by the binding wire without being loosened, accuracy and reliability of detection are improved, and the method is simple and easy to implement.
It can be understood that, through merging the temperature probe, not only can help the arrangement of temperature production line, can reduce test operation's meticulous degree, reduce test pressure, moreover in the temperature probe processing procedure, can effectively reduce the use amount of high temperature sticky tape and tie up the silk to save experimentation cost and test time greatly, the energy saving, reduce cost.
Further, in one embodiment of the present invention, as shown in fig. 3, the end portions of the plurality of temperature probes are respectively formed in a columnar shape, the plurality of temperature probes are sequentially arranged in parallel with each other, and the outer peripheral surfaces of two adjacent temperature probes are in contact with each other.
For example, as shown in fig. 3 and fig. 4, a plurality of temperature probes can be attached by binding a high-temperature adhesive tape, so that a plurality of rows of parallel arrangement can be realized, and the arrangement modes can be various, such as parallel arrangement or overlapped parallel arrangement, so as to be suitable for different detection modes.
Further, in an embodiment of the present invention, at least one set of temperature probes 100 is a plurality of sets, and the plurality of sets of temperature probes are correspondingly fixed on the plurality of temperature detection points.
That is, in the embodiment of the present invention, as shown in fig. 5, 6 and 7, each group of temperature probes includes a plurality of closely arranged temperature probes, such as two temperature probes, three temperature probes, etc., and the temperature probes may be arranged in parallel not only in a single row, but also in multiple rows, and the multi-probe multi-point measurement after arrangement, which is not particularly limited herein.
Further, in an embodiment of the present invention, the plurality of temperature detection points are distributed at intervals on the carrier fluid, for example, the plurality of temperature detection points may be distributed at equal intervals.
It can be understood that accurate temperature rise data collection is achieved through simple hardware operation, a temperature rise curve relation meeting theoretical requirements is obtained through the obtained data, a temperature collection device with high cost is not needed, temperature rise changes can be measured flexibly and in real time, measured point data can be used, data failure and data waste are avoided, and test precision can be further improved through multi-point measurement of a combined temperature probe.
Further, in one embodiment of the invention, the current carrier comprises a lithium ion battery, a lead-acid storage battery, a nickel strip and a steel strip.
That is, the apparatus 10 of the embodiment of the present invention is suitable for a carrier fluid such as a lithium ion battery, a lead acid battery, a nickel strip, a steel strip, or the like. Compared with the detection device in the related art, the embodiment of the invention can achieve the effects of reducing the test pressure, improving the test precision, reducing the test cost and improving the safety factor through simple hardware design change. Especially, compared with the traditional single-probe multi-point temperature rise acquisition method, the method can not meet the requirements of large test quantity and high data processing speed, can provide effective technical support for a large number of electric core tests in the later period, and better meets the use requirements of users. That is to say, the temperature rise of the carrier fluid is measured after the temperature acquisition probes of a plurality of temperature lines are combined in parallel, the temperature probes are in contact with each other in the measurement process by using a parallel combination method, the working strength of binding is reduced, the usage amount of a high-temperature adhesive tape is reduced, and meanwhile, the test precision is improved, and the data selecting and processing speed is increased.
The operation of the apparatus 10 according to an embodiment of the present invention will now be described in detail.
For example, the circuit is connected according to a single-probe multi-collection-point test method, a 0.3 x 8mm nickel tape current-carrying capacity temperature rise test is carried out, the temperature change is recorded within 10min through the current 15A/20A/24A/30A/36A/48A in the test process, the room temperature is set to be 25 ℃ in the test process, and the maximum collection temperature is limited to be 100 ℃. For the high current test, when the temperature reaches the expected requirement, the next process step is skipped, and the test steps are set aside (10s) -constant current charging (× A) -set aside (10min) -finished.
Taking the example of measuring 3 temperature points by the temperature probe, table 1 is a data collection table, and the test results are shown in table 1:
TABLE 1
Thus, when the temperature rise curve is 10min at 15A/20A/24A, the test of 30A/36A/48A reaches the upper temperature limit, and a complete curve graph is not obtained at the time, and the temperature change curves are shown in FIG. 8, FIG. 9 and FIG. 10.
Further, the probes are adjusted to be arranged in parallel and temperature is measured, the above test operation is also performed, table 2 collects data tables, and the test results are shown in table 2:
TABLE 2
Therefore, the three combined probe measurement data are stable, the influence of environmental influence on data accuracy is weakened to a certain extent, a phenomenon of sudden temperature rise and drop is proposed, test data are collected and then processed, and a temperature change curve is obtained as shown in fig. 8, 9 and 10.
In the embodiment of the invention, the existing test operation can be maintained, only the design combination of the temperature acquisition probe is added, and the normal control is carried out, the combined test data is stable according to the test result, and the data of the three measuring points are fully utilized, so that the waste of test preparation time and the data of the measuring points is not caused. That is to say, only simple hardware equipment operation is carried out, the purposes of simplifying test preparation difficulty and lightening test pressure can be achieved, the influence of the environment on temperature data is reduced through parallel arrangement of the temperature sensors, the temperature data of each detection point is fully utilized, and energy and resource waste is avoided.
In brief, in the related art, an unbounded multi-point current-carrying capacity temperature rise curve is obtained in a laboratory, and the test method is as follows: (1) firstly, carrying out high-temperature protection of thermal recovery, preparing a plurality of binding wires, and attaching the thermal recovery on a current carrier; (2) according to the test method, standing for 10 seconds, carrying out constant current charging of 15A/20A/24A/30A/36A/48A, standing for 10 minutes again, waiting for the temperature to be reduced, ending the test and carrying out temperature rise tests of other currents; (3) and (4) sorting and collecting test data, making a temperature rise curve according to the collected test data, and observing temperature change according to the temperature rise curve.
However, in the embodiment of the present invention, the temperature rise curve of the current-carrying capacity after temperature recovery is measured by the following method: (1) parallel combination of the temperature probes is carried out, and the combined temperature probes can be attached and installed on the current carrier by binding wires; (2) according to the test method, standing for 10 seconds, carrying out constant current charging of 15A/20A/24A/30A/36A/48A, standing for 10 minutes again, waiting for the temperature to be reduced, ending the test and carrying out temperature rise tests of other currents; (3) and (4) sorting and collecting test data, making a temperature rise curve according to the collected test data, and observing temperature change according to the temperature rise curve.
As shown in fig. 8, 9 and 10, since the test can be a constant current charging process for the carrier fluid, the theoretical curve should be changed to a temperature gradually rising process and then reach a stable state, it can be known from the temperature rise curve obtained under the condition of 15A/20A/24A, when the temperature probes are not combined, obvious temperature rise fluctuation is generated in each temperature rise process of the test, the fluctuation range is large, the whole evaluation process will be greatly influenced, and the data of the measuring point with the largest temperature rise is adopted in the data processing, so that the data of the two measuring points are invalid, and waste in the test process is caused. However, after the temperature probes are combined, the observed test curve conforms to the theoretical temperature rise curve, when the power is switched on for 15A/20A/24A, the temperature curve meets the condition that the temperature gradually rises and then reaches a stable state, and it can be seen that the fluctuation of the temperature rise curve is far smaller than the curve effect of the temperature probes which are not combined, and the test data collected by each measuring point in the whole test process are effective data which are effectively utilized, so that the pressure for processing the test results is reduced.
According to the temperature detection device of the carrier fluid, the temperature probes are closely arranged, so that the temperature probes are combined to achieve the purpose of parallel arrangement, temperature fluctuation can be counteracted, the temperature detection device is beneficial to arrangement of temperature detection lines, the fineness of test operation can be reduced, the test pressure is reduced, the use amount of high-temperature adhesive tapes and binding wires is reduced, the test cost and the test time are greatly saved, the environmental influence is reduced, the precision of test data is improved, the test data of each detection point is utilized, the data processing data is accelerated, the occurrence of measuring point waste is avoided, the stability of collected data is improved, the accuracy of detection is improved, the reliability of detection is guaranteed, and the temperature detection device is simple and easy to implement.
Further, an embodiment of the present invention discloses a temperature detection device for a carrier fluid, which is provided with the temperature detection device for a carrier fluid described in the above embodiment. The device is provided with the device, a plurality of temperature probes are closely arranged, so that the temperature probes are merged, the parallel arrangement purpose is realized, the temperature fluctuation can be counteracted, the device not only is beneficial to the arrangement of a temperature sampling line, the fine degree of test operation can be reduced, the test pressure is reduced, the use amount of high-temperature adhesive tapes and binding wires is reduced, the test cost and the test time are greatly saved, the environmental influence is reduced, the precision of test data is improved, the test data of each test point is utilized, the data processing data is accelerated, the occurrence of test point waste is avoided, the stability of the collected data is improved, the detection accuracy is improved, the detection reliability is ensured, and the device is simple and easy to realize.
