[0068] It should be noted that the terms "first", "second", etc. in the specification of the present invention and the above-mentioned drawings are used to distinguish similar users, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0069] The following is a detailed description of an embodiment of the heat exchanger fin structure analysis method according to the present invention. Figure 1 As shown, it is a flow chart of the analysis and processing method of the heat exchanger fin structure provided by the present invention, and the specific implementation process includes the following steps:

[0070] Step 101: Obtain sample size parameters of the fin structure.

[0071] The sample size parameters of the fin structure are a large number of size parameters that are analyzed and processed as large data samples, including the sample tube spacing parameters of the fin structure and the sample sheet width parameters of the fin structure. The fin structure is a fin structure of a corrugated louver fin with a tube diameter of 7 mm. For example, Figure 2 As shown, the sample size parameters can be 3304 combinations of sample tube spacing parameters and sample sheet width parameters. Under each cost data, the point with the maximum heat transfer can be found. Similarly, under each heat transfer, the point with the lowest cost can also be found. Under the same cost, the heat transfer can differ by up to 56%. It can be seen that the combination of tube spacing parameters and sheet width parameters has a great influence on the fin performance. Among them, each point can represent a solution, that is, including a set of sample tube spacing parameters and sample sheet width parameters.

[0072] Step 102: Analyze the relationship between cost and heat exchange capacity of the sample tube spacing parameters of the fin structure and the sample sheet width parameters of the fin structure to determine the recommended size parameters of the fin structure.

[0073] Specifically, a preset multi-objective optimization model can be used to perform a multi-objective analysis on the cost and heat exchange relationship between the sample tube spacing parameter of the fin structure and the sample sheet width parameter of the fin structure to obtain a plurality of initial recommended size parameters corresponding to the fin structure. According to a preset screening threshold, a recommended size parameter that meets the screening threshold is obtained from the plurality of initial recommended size parameters. The multi-objective optimization model can be a pre-constructed corresponding Pareto optimal model for multi-objective optimization.

[0074] like Figure 2 As shown in FIG. 1 , the output result obtained after analyzing the relationship between cost and heat exchange capacity of the sample tube spacing parameter of the fin structure and the sample sheet width parameter of the fin structure. In actual implementation, if certain heat exchange requirements are to be met and the cost is controlled within a reasonable range, the above Figure 2 A set of sample tube spacing parameters and sample sheet width parameters corresponding to the optimal point within the dotted line range are defined as recommended values, i.e., recommended size parameters, and then the corresponding target tube spacing parameters and target sheet width parameters can be found through cost data or heat exchange in subsequent steps.

[0075] Step 103: Determine a first correspondence between the recommended size parameters and the cost data, and determine a second correspondence between the recommended size parameters and the heat exchange capacity; based on the first correspondence or the second correspondence, find out the corresponding target size parameters of the fin structure that meet the preset target conditions from the recommended size parameters.

[0076] Specifically, the recommended size parameters include recommended tube spacing parameters and recommended sheet width parameters. The recommended tube spacing parameters and recommended sheet width parameters are respectively determined after cost and heat exchange relationship analysis is performed on the sample tube spacing parameters of the fin structure and the sample sheet width parameters of the fin structure, and the tube spacing and sheet width dimensions that meet the preset cost and heat exchange relationship conditions are determined, and the tube spacing and sheet width dimensions that meet the preset cost and heat exchange relationship conditions are used as recommended values, i.e., the recommended tube spacing parameters and the recommended sheet width parameters.

[0077] In the process of determining the first corresponding relationship between the recommended size parameters and the cost data, the cost data corresponding to the heat exchanger under the recommended size parameters are obtained, and a third corresponding relationship between the recommended tube spacing parameters in the recommended size parameters and the cost data is constructed, that is, Figure 3and constructing a fourth corresponding relationship between the recommended sheet width parameter in the recommended size parameter and the cost data to obtain the corresponding first corresponding relationship, that is, Figure 4 The first corresponding relationship includes the third corresponding relationship and the fourth corresponding relationship.

[0078] In the process of determining the second corresponding relationship between the recommended size parameters and the heat exchange, the heat exchange corresponding to each heat exchanger under the recommended size parameters is obtained, and a fifth corresponding relationship between the recommended tube spacing parameter in the recommended size parameters and the heat exchange is constructed, that is, Figure 5 The corresponding relationship shown in FIG. 1 is constructed, and the sixth corresponding relationship between the sheet width parameter in the recommended size parameter and the heat exchange amount is constructed, that is, Figure 6 The corresponding relationship shown in the figure is used to obtain the corresponding second corresponding relationship. The second corresponding relationship includes the fifth corresponding relationship and the sixth corresponding relationship.

[0079] Specifically, the preset target condition includes the highest heat exchange under the same cost or the lowest cost under the same heat exchange. Accordingly, based on the first corresponding relationship or the second corresponding relationship, the target size parameter of the fin structure that meets the preset target condition is found from the recommended size parameter, and the corresponding implementation process includes: based on the first corresponding relationship, finding the size parameter corresponding to the highest heat exchange under the same cost from the recommended size parameter as the target size parameter of the fin structure; or, based on the second corresponding relationship, finding the size parameter corresponding to the lowest cost under the same heat exchange as the target size parameter of the fin structure from the recommended size parameter; wherein the target size parameter includes a target tube spacing parameter and a target sheet width parameter.

[0080] When analyzing the heat exchange of different recommended size parameters under the same cost condition, the recommended tube spacing parameter and the recommended sheet width parameter included in the recommended size parameter can be divided into several interval groups, wherein each interval group includes a mapping relationship between a pair of tube spacing intervals and sheet width intervals; when the cost data are the same, the corresponding first tube spacing parameter and first sheet width parameter are obtained based on the first corresponding relationship; when the first tube spacing parameter and the first sheet width parameter are respectively located in a pair of tube spacing intervals and sheet width intervals with a mapping relationship, the first tube spacing parameter and the first sheet width parameter are respectively determined as the target tube spacing parameter and the target sheet width parameter.

[0081] When analyzing the costs of different recommended dimension parameters under the same heat exchange capacity, the recommended tube pitch parameter and the recommended fin width parameter included in the recommended dimension parameters can be divided into several interval groups, where each interval group includes a mapping relationship between a pair of tube pitch intervals and fin width intervals; under the condition of the same heat exchange capacity, the corresponding second tube pitch parameter and the second fin width parameter are obtained based on the second corresponding relationship; when the second tube pitch parameter and the second fin width parameter are respectively located within a pair of tube pitch intervals and fin width intervals with a mapping relationship, the second tube pitch parameter and the second fin width parameter are respectively determined as the target tube pitch parameter and the target fin width parameter. For example, according to Figures 3 to 6 , the recommended dimension parameters can be obtained from the perspective of cost data or heat exchange capacity, and they are divided into 6 interval groups: Pt>22, Pl<17.5; 21<Pt≤22, 17.5≤Pl<18.2; 20<Pt≤21, 18.2≤Pl<18.7; 19<Pt≤20, 18.7≤Pl<19.3; 18<Pt≤19, 19.3≤Pl<20; Pt≤18, Pl≥20; where Pt is the recommended tube pitch parameter and Pl is the recommended fin width parameter. The first tube pitch parameter in the corresponding recommended dimension parameters obtained by comparison based on the first corresponding relationship is 21, and the first fin width parameter is 18.2. The tube pitch parameter with the same cost can also be 20, and the fin width parameter can also be 16.5. Under the same working conditions, after CFD calculation, it can be known that the heat exchange capacity with the first tube pitch parameter of 21 and the first fin width parameter of 18.2 is 2.35% higher than that with the tube pitch parameter of 20 and the fin width parameter of 16.5 at the same cost. Through multiple comparisons, the first tube pitch parameter of 21 and the first fin width parameter of 18.2 can be obtained as the target tube pitch parameter and the target fin width parameter. In addition, the first tube pitch parameter in the corresponding recommended dimension parameters obtained by comparison based on the first corresponding relationship is 18.375, and the first fin width parameter is 19.5. The tube pitch parameter with the same cost can also be 19, and the fin width parameter can also be 21. Under the same working conditions, after CFD calculation, it can be known that the heat exchange capacity with the first tube pitch parameter of 18.375 and the first fin width parameter of 19.5 is 1.68% higher than that with the tube pitch parameter of 19 and the fin width parameter of 21. Through multiple comparisons, the first tube pitch parameter of 18.375 and the first fin width parameter of 19.5 can be obtained as the target tube pitch parameter and the target fin width parameter. By dividing the tube pitch parameter and the fin width parameter into 6 interval groups, each interval group includes a tube pitch interval and a fin width interval. When the designed finned tube pitch parameter and fin width parameter fall within these two intervals at the same time, the heat exchanger has the best heat exchange performance. In this example, the grouping interval is controlled within 1mm, which can ensure that the performance of each group of fins reaches or approaches the highest level.

[0082] The present invention calculates the fins with different tube spacing parameters and sheet width parameters, and can obtain the optimal fin size and its optimal combination of the 7mm corrugated louver fins, that is, the target tube spacing parameter and the target sheet width parameter corresponding to the target size parameter, from Figure 2 It can be clearly seen that the selected optimal size can achieve the highest heat transfer at the same cost, or the lowest cost at the same heat transfer. By accurately dividing the interval groups, it is ensured that the values ​​in the above interval groups reach or approach the target size parameters. Each target interval group includes a tube spacing interval and a sheet width interval. These two intervals constitute a set of optimal intervals (i.e., target interval groups). When the tube spacing parameters and sheet width parameters of the designed fins fall within these two intervals at the same time, the heat exchanger has the best heat transfer performance.

[0083] The analysis and processing method of the heat exchanger fin structure provided by the present invention performs a cost-heat exchange relationship analysis on the sample tube spacing parameters and the sample sheet width parameters of the fin structure to determine the recommended size parameters of the fin structure, determine the first corresponding relationship between the recommended size parameters and the cost data, and determine the second corresponding relationship between the recommended size parameters and the heat exchange, and further find the corresponding target size parameters of the fin structure that meet the preset target conditions from the recommended size parameters based on the first corresponding relationship or the second corresponding relationship. The method can quickly determine the optimal size parameters of the fin structure, improve the rationality of the size parameter setting, and thus improve the performance of the heat exchanger.
