[0002] The automobile air conditioner evaporator is a key component in the refrigeration system, and its function is to realize refrigeration through heat exchange with air. The uniformity of the evaporator surface temperature directly affects the refrigeration effect and passenger comfort. If the evaporator surface temperature is unevenly distributed, it may cause local overcooling or overheating, thereby affecting the performance and energy efficiency of the air conditioning system.

[0003] The biggest highlight of detecting the evaporator temperature uniformity in the automobile air conditioning system is that it can provide accurate and reliable support for system engineers during system integration, thereby optimizing system design, improving overall performance and ensuring product quality. System engineers select sensor positions on the evaporator surface based on the data detected by the evaporator temperature uniformity. The function of the sensor is to prevent the evaporator from frosting or icing and to protect the compressor.

[0004] The traditional temperature uniformity detection tool is to install a grid in the wind tunnel, and arrange temperature sensors at the intersection to monitor the temperature distribution of the evaporator surface in real time. Another method is to evenly divide the evaporator into several equal parts and then use fine iron wire to make a grid on the evaporator. Then arrange temperature sensors at the intersection of the grid lines.

[0005] When arranging temperature sensors, the grid installed in the wind tunnel needs to be operated accurately, which takes a long time. Because the grid in the wind tunnel is limited to some extent, it is not easy to adjust the position of different products, and the distance between each sensor probe and the product surface is difficult to control, so it needs to be adjusted accordingly.

[0049] Embodiment 1:

[0050] As shown in the figure, an automobile air conditioner evaporator temperature uniformity detection tool comprises: Figures 1-14 The fixed frame 1, the X axial line 2 and the Y axial line 3;

[0051] The fixed frame 1 is arranged in a square box type, and the middle part of the fixed frame 1 is hollow, and the hollow part in the middle is used for installing an automobile air conditioner evaporator;

[0052] The fixed frame 1 is arranged in a square box type, and the middle part of the fixed frame 1 is hollow, and the hollow part in the middle is used for installing an automobile air conditioner evaporator;

[0053] The X-axis lines 2 are arranged in the hollow part of the middle of the fixed frame 1 in parallel to the transverse direction of the fixed frame 1, and a plurality of groups are arranged equidistantly along the longitudinal direction of the fixed frame 1;

[0054] The Y-axis lines 3 are arranged in the hollow part of the middle of the fixed frame 1 in parallel to the longitudinal direction of the fixed frame 1, and a plurality of groups are arranged equidistantly along the transverse direction of the fixed frame 1, and the Y-axis lines 3 and the X-axis lines 2 intersect with each other to form a plurality of temperature steps 4 for mounting sensors, and the sensors can be directly hung at the temperature steps 4 by hooks or fixed at the temperature steps 4 by binding and bundling. Since the X-axis lines 2 and the Y-axis lines 3 intersect with each other to form a grid, the installation position of the sensors can be accurately determined through the grid, and the distribution points where the sensors need to be installed can be clearly determined, and the distribution of the sensors can be directly determined.

[0055] The middle part of the fixed frame 1 is provided with a limiting plate 11 for limiting the automobile air conditioner evaporator, and the limiting plate 11 includes corner limiting plates 111 located at the four corners of the inner side of the fixed frame 1 and middle limiting plates 112 located at the side middle plates.

[0056] Specifically, the middle part of the fixed frame 1 is a square opening, the X-axis lines 2 and the Y-axis lines 3 are distributed perpendicularly and intersectingly at the opening, the two ends of the X-axis lines 2 and the Y-axis lines 3 are fixed on the fixed frame 1, and the straightness of the X-axis lines 2 and the Y-axis lines 3 is ensured.

[0057] The automobile air conditioner evaporator is installed below the grid formed by the combination of the X-axis lines 2 and the Y-axis lines 3 through the limiting plate 11, and then the sensors are hung at the temperature steps 4 according to the requirements, and the automobile air conditioner evaporator is detected through the sensors.

[0058] In addition, in order to adapt to the detection of automobile air conditioner evaporators of different specifications and models, and to form detection of different levels and detection accuracy, the density of the grid formed by the combination of the X-axis lines 2 and the Y-axis lines 3 can be adjusted.

[0059] Specifically, along the middle line of the longitudinal side of the fixed frame 1, the X-axis lines 2 on both sides adjust the spacing of adjacent X-axis lines 2 through X-axis adjusting assemblies, and along the middle line of the transverse side of the fixed frame 1, the Y-axis lines 3 on both sides adjust the spacing of adjacent Y-axis lines 3 through Y-axis adjusting assemblies.

[0060] The adjusting structure of the X-axis adjusting assembly and the Y-axis adjusting assembly is the same, and both include a moving block 51, a lead screw unit 52, a guide rod 53, and a multi-link unit 54.

[0061] The moving block 51 is symmetrically arranged at both ends of the X-axis line 2 or the Y-axis line 3, and is movably arranged on the side wall of the fixed frame 1. Both ends of the X-axis line 2 or the Y-axis line 3 are fixed on the fixed frame 1 through the moving block 51. The fixed frame 1 is provided with a notch 101 corresponding to the position of both ends of the X-axis line 2 or the Y-axis line 3, through which the X-axis line 2 or the Y-axis line 3 passes.

[0062] The lead screw unit 52 is arranged along the transverse direction and / or the longitudinal direction of the fixed frame 1. The lead screw nut 521 on the lead screw unit 52 is installed on the moving block 51 at the same side of both ends of the fixed frame 1. The lead screw 522 on the lead screw unit 52 is provided with symmetrically arranged right and left threads. Specifically, the lead screw unit 52 is composed of a group of lead screws 522 and two groups of lead screw nuts 521. The two groups of lead screw nuts 521 are respectively located at the right and left threads of the lead screw 522. The lead screw nut 521 is installed on the moving block 51 at both ends. Through the rotation of the lead screw 522, the lead screw nuts 521 at both ends can move towards or away from each other, thereby driving the moving blocks 51 at both ends to move. The moving blocks 51 located between the two ends are sleeved on the lead screw 522 through the large through hole.

[0063] The guide rod 53 is arranged through the moving block 51 at the same side of the fixed frame 1. The guide rod 53 guides the movement of the moving block 51, so that the moving block 51 slides on the guide rod 53.

The midpoint of the connecting rod 541 of the multi-link unit 54 is fixedly arranged with the corresponding moving block 51. The multi-link unit 54 drives the moving block 51 at the same side of the fixed frame 1 to move synchronously. Due to the arrangement of the multi-link unit 54, when the moving blocks 51 at both ends move, the remaining moving blocks 51 also move through the linkage of the multi-link unit 54, thereby adjusting the distance between the X-axis line 2 and the Y-axis line 3. It should be noted that the two ends of the multi-link unit 54 are hingedly connected with the fixed frame 1 to ensure stable operation of the multi-link unit 54.

[0065] Specifically, during the operation of the multi-link unit 54, with the movement of the moving blocks 51 at both sides, the included angle between the adjacent hingedly connected connecting rods 541 increases or decreases. When the included angle between the connecting rods 541 increases, the distance between the moving blocks 51 increases, and correspondingly the distance between the X-axis line 2 or the Y-axis line 3 increases. Conversely, when the included angle between the connecting rods 541 decreases, the distance between the moving blocks 51 decreases, and correspondingly the distance between the X-axis line 2 or the Y-axis line 3 decreases.

[0066] In addition, in order to ensure that the moving blocks 51 at both ends of the X-axis line 2 or the Y-axis line 3 can be adjusted synchronously, parallel to the wire rod 522, the wire rod 522 is connected to the chain wheel transmission unit 55, and the hand-operated wheel 56 is arranged on the wire rod 522, and the wire rod 522 on the corresponding side is rotated by rotating the hand-operated wheel 56, so that the wire rod 522 on the opposite side is rotated synchronously by the chain wheel transmission unit 55, thereby realizing synchronous adjustment of the moving blocks 51 on both sides and realizing adjustment of the distance between the X-axis line 2 or the Y-axis line 3.

[0067] Furthermore, the top of each group of the moving blocks 51 is threadedly connected to a group of adjusting screws 511, and the ends of the X-axis line 2 or the Y-axis line 3 are wound on the adjusting screws 511, so that the corresponding X-axis line 2 or Y-axis line 3 is tightened by rotating the adjusting screw 511 when the X-axis line 2 or the Y-axis line 3 is loose, thereby avoiding height difference of the inductor hung on the temperature step 4, ensuring detection accuracy, and the moving block 51 is provided with a threaded hole 512 for the adjusting screw 511, the upper part of the threaded hole 512 is provided with a take-up groove 513, the side wall of the take-up groove 513 is provided with a threading hole 514, and the cylindrical body of the adjusting screw 511 is provided with a wire clamping groove 515 for winding the X-axis line 2 or the Y-axis line 3.

[0068] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
