Description

Technical Field

[0001] The present invention relates to the field of heat transfer performance of vehicle battery coolers, and particularly to an evaluation method, system and device based on the placement mode of battery coolers. Background Art

[0002] The placement modes (vertical placement, horizontal placement, inverted placement, etc.) of the battery coolers of new energy passenger vehicles directly affect their heat transfer power and pressure drop performance by changing the relative relationship between the refrigerant flow direction and the gravity direction. When the refrigerant flow direction is opposite to the gravity direction, the evaporated liquid refrigerant is more easily carried by the air flow to form an annular flow or a mist flow, reducing the gas-liquid stratification phenomenon and enhancing the gas-liquid mixing effect, thereby improving the heat transfer power. However, at the same time, gravity will hinder the refrigerant flow, resulting in an increase in pressure drop. When the flow direction is the same as the gravity direction, the gravity makes the liquid-phase refrigerant flow downward faster, resulting in a thinner or even broken liquid film and a decrease in heat transfer power, but the gravity-assisted flow reduces the pressure drop. In the case where the flow direction is perpendicular to the gravity direction, the gravity makes the liquid-phase refrigerant deposit at the bottom of the plate while the gas phase accumulates at the upper part, forming an obvious stratified flow, which will significantly reduce the heat transfer power. At this time, the system pressure drop is jointly determined by the gravity pressure drop and the frictional pressure drop. These correlation laws between the flow characteristics and the heat transfer performance provide an important basis for the optimal design of battery coolers.

[0003] Currently, the performance evaluation of battery coolers mainly relies on experimental testing methods, that is, directly analyzing the heat transfer power and pressure drop data obtained through actual measurement. However, this method has the following obvious limitations: First, experimental testing requires setting up a special test bench and consuming a large amount of energy, resulting in high evaluation costs; Second, this method can only obtain the performance data under specific placement modes and cannot establish a universal correlation model between the placement mode and the heat transfer performance, so it is difficult to predict the performance of other untested placement modes. These limitations seriously restrict the optimal design and performance improvement of battery coolers.

[0004] Therefore, it is necessary to propose an evaluation scheme for the heat transfer performance of battery coolers for new energy vehicles to solve the above technical problems. Summary of the Invention

Detailed implementation manners

[0019] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. It should be noted, however, that these embodiments do not limit the present invention, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art according to these embodiments shall fall within the protection scope of the present invention.

[0020] The technical solutions provided by each embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0021] Embodiment 1: As Figure 1 shown, Embodiment 1 provides an evaluation method based on the placement method of a battery cooler (hereinafter referred to as the "evaluation method" or "method") to solve the problems that the performance detection method of the battery cooler in the prior art has high test costs and cannot predict the heat transfer performance under different placement methods. In this embodiment, the battery cooler has a length of 185 mm, a width of 78 mm, and a height of 65 mm. The method of this embodiment includes:

[0022] Step 101. Obtain the heat transfer effect values of the battery cooler under different placement methods, and obtain the corresponding direction influence factors and refrigerant flow dimensions for different direction relationships.

[0023] As Figure 2 shown, the operation of "obtaining the heat transfer effect values of the battery cooler under different placement methods" in Step 101 specifically includes: Step 201. Measure the heat transfer power and pressure drop corresponding to different placement methods.

[0024] Conduct tests on the heat transfer effects of the battery cooler under different placement methods to obtain the heat transfer power and pressure drop under different placement methods as the heat transfer performance data of the battery cooler.

[0025] Specifically, in this embodiment, the battery cooler of a certain new energy passenger vehicle is placed vertically, horizontally, and upside down, and the heat transfer power and pressure drop are measured. The measurement results are shown in Table 1.

[0026] Table 1 Heat transfer performance data of the battery cooler under different placement methods: Placement method Heat transfer power (kW) Pressure drop (kPa) Heat transfer performance data Vertically placed 3.521 4.8 4.1605 Horizontally placed 2.434 4.0 3.217 Inverted placement 3.025 4.9 3.9625 Step 202. Take the average value between the corresponding heat transfer power and pressure drop as the corresponding heat transfer performance data, and process the heat transfer performance data to form the corresponding heat transfer effect value.

[0027] The heat transfer performance data measured according to Table 1, with the final result of a certain placement method as the benchmark, solve the change ratio of the heat transfer effect under other different placement methods, and the obtained ratio can characterize the heat transfer effect value. For example, taking the heat transfer effect value corresponding to the heat transfer performance data when placed horizontally as 1 as the benchmark, it can be obtained that the heat transfer effect value when placed vertically is 1.293, and the heat transfer effect value when placed upside down is 1.232.

[0028] By comparing and analyzing the test data of different placement methods to reveal the influence law of the installation orientation of the battery cooler on its comprehensive performance, and provide an optimization basis for the design of the battery thermal management system. In this embodiment, boundary conditions such as flow rate and temperature are strictly controlled to ensure data comparability.

[0029] In step 101, the specific operation of "obtaining the direction influence factor corresponding to different direction relationships" includes: setting the influence factor value corresponding to the case where the refrigerant flow direction is opposite to the gravity direction to 3 points; setting the influence factor value corresponding to the case where the refrigerant flow direction is the same as the gravity direction to 2 points; setting the influence factor value corresponding to the case where the refrigerant flow direction is perpendicular to the gravity direction to 1 point.

[0030] For the refrigerant flow size, the flow length under different placement methods can be directly measured. In this embodiment, when the battery cooler is placed vertically, the refrigerant flow size L1 in the direction where the refrigerant flow direction is opposite to the gravity direction is 0.185 m, and the refrigerant flow sizes in the perpendicular direction are two components of 0.078 m and 0.065 m (L3 1 and L3 2 ), and the refrigerant flow size L2 in the same direction is 0; when the battery cooler is placed upside down, the refrigerant flow size L1 in the direction where the refrigerant flow direction is opposite to the gravity direction is 0.065 m, and the refrigerant flow sizes in the perpendicular direction are two components of 0.185 m and 0.078 m (L3 1 and L3 2 ), and the refrigerant flow size L2 in the same direction is 0; when the battery cooler is placed horizontally, the refrigerant flow size L1 in the direction where the refrigerant flow direction is opposite to the gravity direction is 0, and the refrigerant flow sizes in the perpendicular direction are two components of 0.065 m and 0.078 m (L3 1 and L3 2 ), and the refrigerant flow size L2 in the same direction is 0.078 m.

[0031] Step 102. Determine the corresponding size influence factor based on the heat transfer effect value, refrigerant flow size, and direction influence factor.

[0032] As Figure 3 shown, step 102 specifically includes: Step 301. Establish a relationship model between the heat transfer effect values corresponding to different placement methods and different directional relationships, the direction influence factor, the refrigerant flow size, and the influence factor of the dimension to be calibrated. The establishment process of this relationship model is as follows: The sum of the products of the direction influence factors X i corresponding to different placement methods and different directional relationships, L i the refrigerant flow size, Y i and the influence factor of the dimension to be measured S j is used as the corresponding heat transfer effect value S j . That is, , (Equation 1), where, i represents different mutual relationships between the refrigerant flow direction and the gravity direction, j represents different placement methods of the battery cooler. In this embodiment, X 1 represents the direction influence factor when the refrigerant flow direction is opposite to the gravity direction, X 2 is the direction influence factor when the refrigerant flow direction is the same as the gravity direction, X 3 is the direction influence factor when the refrigerant flow direction is perpendicular to the gravity direction. Y 1 is the dimension influence factor when the refrigerant flow direction is opposite to the gravity direction, Y 2 is the dimension influence factor when the refrigerant flow direction is the same as the gravity direction, Y 3 is the dimension influence factor when the refrigerant flow direction is perpendicular to the gravity direction. L 1 is the refrigerant flow size when the refrigerant flow direction is opposite to the gravity direction, L 2 is the refrigerant flow size when the refrigerant flow direction is the same as the gravity direction, L 3 is the refrigerant flow size when the refrigerant flow direction is perpendicular to the gravity direction. S 1 is the heat transfer effect value when the battery cooler is placed vertically, S 2 is the heat transfer effect value when the battery cooler is placed upside down, S 3 is the heat transfer effect value when the battery cooler is placed horizontally.

[0033] Step 302. Based on the known heat transfer effect value S j , the refrigerant flow size L i and the direction influence factor X i solve the corresponding influence factor of the dimension to be calibratedY i .

[0034] Substitute the heat transfer effect value obtained in step 101 S j , the direction influence factor X i , and the refrigerant flow size L i into Equation 1 respectively to form a system of equations for the heat transfer effect values under different placement methods, as shown in Equation 2: , (Equation 2), Solve the system of equations, that is, Equation 2, to obtain the size influence factor Y 1 = 1.388, Y 2 = 0.553, Y 3 = 3.655.

[0035] Step 103. Predict the heat transfer effect of the battery cooler in different placement methods according to the direction influence factor, the refrigerant flow size, and the size influence factor.

[0036] Among them, if the sum of the products of the direction influence factor X i , the refrigerant flow size Y i and the size influence factor to be measured L i in different direction relationships under different placement methods (that is S j ) is larger, the heat transfer effect of the battery cooler at the corresponding placement position is better; conversely, if the sum of the products of the direction influence factor X i , the refrigerant flow size Y i and the size influence factor to be measured L i in different direction relationships under different placement methods (that is S j ) is smaller, the heat transfer effect of the battery cooler at the corresponding placement position is worse.

[0037] It can be understood that substituting the size influence factor Y i obtained according to Equation 2, the direction influence factor obtained above X i 、 and the refrigerant flow size L i into Equation 1 can obtain the heat transfer effect values under different placement methods, that is, the heat transfer effect value when placed vertically S1 = 1.293, heat transfer effect value when placed upside down S 2 = 1.232, heat transfer effect value when placed horizontally S 3 = 1. Thus, the heat transfer effect of the battery cooler in this embodiment is the best when placed vertically.

[0038] Of course, since all parameter values remain unchanged when calculating the heat transfer effect value, the obtained heat transfer effect value is consistent with the heat transfer effect value measured in step 201. Therefore, to detect the heat transfer effect of other placement methods, the heat transfer effect of the battery cooler placed in an inverted manner (flipping the placement method when placed upside down by 180 degrees so that the coolant inlet and outlet change from the upper side to the lower side, and the refrigerant inlet and outlet change from the lower side to the upper side) is predicted below. Of course, the heat transfer effect of other placement methods of the battery cooler can also be predicted, which will not be specifically described one by one here.

[0039] When the battery cooler is inverted, the refrigerant flow dimension L1 is 0 when the refrigerant flow direction is opposite to the gravity direction, and the refrigerant flow dimension L2 is 0.065 m when they are the same. The vertical refrigerant flow dimension L3 has two components of 0.185 m and 0.078 m (L3 1 and L3 2 ), and according to Equation 1, the heat transfer effect of the inverted placement method is calculated as follows: S 4 = 2×0.065×0.553 + 1×0.185×3.655 + 1×0.078×3.655 = 1.033, Through comparative analysis, it can be seen that S 3 < S 4 < S 2 < S 1 , that is, in this embodiment, the heat transfer effect of the battery cooler is the best when placed vertically, followed by when placed upside down, and the worst when placed horizontally. That is, the evaluation method of this embodiment can conveniently, quickly, and simply evaluate the heat transfer performance of any battery cooler, solving the defects such as high cost of the existing evaluation methods.

[0040] It should be noted that the prediction results of this embodiment 1 show that among the battery coolers with the current limited size, the heat transfer effect of the vertical placement method is the best. This conclusion only applies to the coolers with specific specifications in this embodiment. For battery coolers of other sizes, the heat transfer performance can be predicted by referring to the evaluation method of this embodiment in combination with specific specification parameters and installation methods. Of course, the method of this embodiment can also be used for the remaining placement methods of the battery cooler (such as at 30 ° , 60 °Predict the heat transfer effect (such as equal-angle oblique placement, etc.). The specific prediction principle is the same as above and will not be elaborated here.

[0041] In addition, the method of Embodiment 1 constructs a system of equations for solving the size influence factor through three placement methods: horizontal placement, vertical placement, and upside-down placement. It is also possible to construct a system of equations through any three of the horizontal placement, vertical placement, upside-down placement, and inverted buckling methods to solve the size influence factor and improve the accuracy of predicting the heat transfer performance of the battery cooler.

[0042] In summary, the evaluation method based on the placement method of the battery cooler in Embodiment 1 determines the corresponding size influence factor value according to the heat transfer effect value, refrigerant flow size, and direction influence factor of the battery cooler corresponding to different direction relationships under different placement methods. Thus, the heat transfer effect of the battery cooler is predicted by combining the heat transfer effect value, refrigerant flow size, direction influence factor, and size influence factor value of the battery cooler in each direction under different placement methods. In this way, not only can the heat transfer performance of the battery cooler under different placement methods be predicted by establishing the relationship between the placement method and the heat transfer performance, but also the experimental cost can be greatly reduced, and the optimal design and performance of the battery cooler are greatly improved, thus solving the problem that the performance detection method of the battery cooler in the prior art has a high experimental cost and cannot predict the heat transfer performance under different placement methods.

[0043] Embodiment 2: As Figure 4 shown, Embodiment 2 also provides an evaluation system 400 based on the placement method of the battery cooler, which includes: a heat transfer data acquisition unit 401 for acquiring the heat transfer effect value of the battery cooler under different placement methods; a direction influence factor acquisition unit 402 for acquiring the corresponding direction influence factor under different direction relationships; a flow size acquisition unit 403 for acquiring the corresponding refrigerant flow size under different direction relationships; a size influence factor determination unit 404 for determining the corresponding size influence factor based on the heat transfer effect value, refrigerant flow size, and direction influence factor; and a prediction unit 405 for predicting the heat transfer effect of the battery cooler in different placement methods according to the direction influence factor, refrigerant flow size, and size influence factor. Among them, the size influence factor determination unit 404 includes a model establishment unit 4041 for establishing a relationship model between the heat transfer effect value corresponding to different placement methods and different direction relationships and the direction influence factor, refrigerant flow size, and to-be-calibrated size influence factor; and a calculation unit 4042 for solving the corresponding to-be-calibrated size influence factor according to the known heat transfer effect value, refrigerant flow size, and direction influence factor.

[0044] It should be understood that the evaluation system 400 based on the placement method of the battery cooler in this Embodiment 2 determines the size influence factor value corresponding to the refrigerant flow size obtained by the flow size acquisition unit 403, the direction influence factor corresponding to different direction relationships obtained by the direction influence factor acquisition unit 402, and the heat transfer effect value of the battery cooler under different placement methods obtained by the heat transfer data acquisition unit 401 through the size influence factor determination unit 404. Thus, the prediction unit 405 combines the heat transfer effect value, refrigerant flow size, direction influence factor, and size influence factor value of the battery cooler in each direction under different placement methods to predict the heat transfer effect of the battery cooler. In this way, the evaluation system 400 of this Embodiment 2 can not only predict the heat transfer performance of the battery cooler under different placement methods through the relationship between the placement method and the heat transfer performance, but also greatly reduce the experimental cost, greatly improve the optimal design and performance of the battery cooler, thereby solving the problem that the performance detection method of the battery cooler in the prior art has a high experimental cost and cannot predict the heat transfer performance under different placement methods.

[0045] It should be noted that for the technical solutions of the same parts of the evaluation system 400 based on the placement method of the battery cooler in this Embodiment 2 as those in Embodiment 1, please refer to Embodiment 1 and will not be elaborated here.

At the same time, this Embodiment 3 uses the relationship between the placement method and the heat transfer performance to predict the heat transfer effect of the battery cooler under different placement methods, so as to improve the optimal design and performance of the battery cooler, solve the problems of the reliability, energy efficiency, and space adaptability of the battery thermal management system, and can also greatly reduce the experimental cost.

[0048] With such a setting, the device 500 for evaluating the heat exchange performance of the battery cooler achieves heat transfer through the refrigerant circulation system, combines with the controller 502 to precisely control the battery temperature, and while improving the energy efficiency and reliability of the system, innovatively establishes a prediction model for the placement method and heat exchange performance. In this Embodiment 3, not only the heat exchange effects in different orientations such as vertical placement, horizontal placement, upside-down placement, and inverted buckling are predicted to guide the optimization of the cooler flow channel and structure, but also it can directly address the key challenges of the battery thermal management system in terms of reliability (such as avoiding local overheating), energy efficiency (reducing pump power loss), and space adaptability (compact layout). At the same time, by replacing physical experiments with simulation experiments, the R & D cost and cycle are significantly reduced.
