[0002] The proportion of electronic components used in automotive parts is increasing. Among these electronic components, some automotive parts use high-current components. These high-current automotive parts undergo EMC testing (electromagnetic compatibility testing) before leaving the factory to ensure product quality. However, EMC testing equipment accumulates heat during long-term operation and needs to be equipped with corresponding heat dissipation devices to ensure stable operation.

[0003] In the invention patent application CN202221537233.1, published on January 3, 2023, entitled "A Heat Dissipation Device for EMC Testing of High-Current Automotive Components", a heat dissipation fan is included. The heat dissipation fan has an external frame. A slot is provided inside one side of the frame. A slot is provided at one end of the slot. A movable groove is provided above the slot. A connecting rod passing through the frame is provided inside the movable groove. A spring A is sleeved on the outside of the connecting rod. A locking block is provided on the other side of the frame. The locking block is locked into the slot. A spring groove is provided inside one end of the locking block. A spring B is provided inside the spring groove. A plug is provided at one end of the spring B. The plug is inserted into the slot. When installing multiple heat dissipation devices, the multiple individual units are first connected to each other in the above manner. Then, the connected heat dissipation devices are fixed with bolts between adjacent individual units.

[0004] In actual use, the installation of multiple heat dissipation devices requires the use of bolts for fixing, which makes the installation of multiple heat dissipation devices time-consuming and labor-intensive. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] This utility model provides a heat dissipation device for EMC testing of high-current automotive parts, which solves the problem that bolts are needed to fix multiple heat dissipation devices when installing them, which leads to time and labor costs.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows: a heat dissipation device for EMC testing of high-current automotive components, comprising a mounting box, a heat dissipation groove provided on the upper surface of the mounting box, limit grooves provided on both sides of the heat dissipation groove, a cooling fan body provided on the surface of the heat dissipation groove, a power connector provided on one side of the cooling fan body, a top rod retaining plate slidably connected to one side surface of the mounting box, a plug slot provided on the outer surface of the limit groove, and fixing holes provided on the four sides of the cooling fan body.

[0009] The mounting box includes a skateboard base plate, the surface of which is provided with a pop-out perforation, a linkage pull plate is provided below the skateboard base plate, an insert top rod is fixedly connected to the upper surface of the linkage pull plate, a tension spring is sleeved on the surface of the insert top rod, and a ventilation window is provided on one side of the pop-out perforation on the surface of the skateboard base plate.

[0010] Furthermore, a limiting slider is provided on the other side of the cooling fan body, and the cooling fan body forms a sliding structure on the surface of the limiting groove through the power connector and the limiting slider. The top rod plate forms a sliding structure on the surface of the heat dissipation groove and the slide plate base, and the top rod plate forms a pull-out structure on one side of the mounting box.

[0011] Furthermore, the number and vertical position of the pop-out perforations and the insertion top rods are the same, the upper surface of the tension spring is fixedly connected to the lower opening of the pop-out perforation, and the insertion top rods and the linkage pull plate form an elastic structure on the surface of the pop-out perforation through the tension spring.

[0012] Furthermore, the insertion rod is fixed in position by a rod retainer plate, so that the insertion rod is fixed inside the pop-out hole. One end of the rod retainer plate extends out from one side of the mounting box and has a groove on its surface.

[0013] Furthermore, the cooling fan body is connected to the insert top rod through a fixing hole on its surface.

[0014] 3. Beneficial effects:

[0015] This utility model has a reasonable design. When installing one or more cooling fan bodies, the cooling fan body is inserted from both sides of the heat dissipation groove. When the heat dissipation device enters the bottom of the heat dissipation groove, the fixing holes around it align with the pop-out holes. At the same time, another cooling fan body is inserted into the heat dissipation groove. The limiting groove prevents the cooling fan body from falling off the surface of the heat dissipation groove. By pulling out the groove on the surface of the top rod clamping plate on one side of the mounting box, the top rod clamping plate is pulled out from the upper surface of the slide plate bottom plate. The inserting top rod and the linkage pull plate pop out from the pop-out holes under the action of the tension spring, and at the same time enter the fixing holes around the surface of the cooling fan body for fixation. This also prevents the cooling fan body from sliding out of the opening end of the heat dissipation groove, realizing the quick installation of the cooling fan body. When it is necessary to reduce the number of cooling fan bodies, the fixing of the cooling fan body is released by pulling the linkage pull plate, realizing the purpose of quick disassembly.

[0026] See attached document Figure 1-4 The device includes a mounting box 1, with a heat dissipation groove 2 on the upper surface of the mounting box 1, and limiting grooves 3 on both sides of the heat dissipation groove 2. A cooling fan body 4 is mounted on the surface of the heat dissipation groove 2, and a power connector 5 is mounted on one side of the cooling fan body 4. A top rod plate 6 is slidably connected to one side of the mounting box 1. A plug slot 7 is mounted on the outer surface of the limiting groove 3. Fixing holes 8 are mounted on all four sides of the cooling fan body 4. A limiting slider is mounted on the other side of the cooling fan body 4. The cooling fan body 4 forms a sliding structure on the surface of the limiting groove 3 through the power connector 5 and the limiting slider. The top rod plate 6 forms a sliding structure on the surface of the heat dissipation groove 2 and the sliding plate base 101, and the top rod plate 6 forms a pull-out structure on one side of the mounting box 1. This device achieves the purpose of quickly disassembling multiple or a single cooling fan body 4 by freely extending and retracting the inserting top rod 104 in the mounting box.

[0027] The mounting box 1 includes a skateboard base plate 101. The surface of the skateboard base plate 101 is provided with pop-out perforations 102. A linkage pull plate 103 is provided below the skateboard base plate 101. A through-rod 104 is fixedly connected to the upper surface of the linkage pull plate 103. A tension spring 105 is sleeved on the surface of the through-rod 104. A ventilation window 106 is provided on one side of the pop-out perforation 102 on the surface of the skateboard base plate 101. The number and vertical position of the pop-out perforations 102 and the through-rod 104 are the same. The upper surface of the spring 105 is fixedly connected to the lower opening of the pop-out through hole 102. The through rod 104 and the linkage pull plate 103 form an elastic structure on the surface of the pop-out through hole 102 through the tension spring 105. The through rod 104 is fixed in position by the rod retaining plate 6, so that the through rod 104 is fixed inside the pop-out through hole 102. One end of the rod retaining plate 6 extends out from one side of the mounting box 1 and has a groove on its surface. The cooling fan body 4 is fitted and connected to the through rod 104 through the fixing hole 8 on its surface.

[0028] When installing one or more cooling fan bodies 4, the cooling fan body 4 is inserted from both sides of the heat dissipation slot 2. When the heat dissipation device enters the bottom of the heat dissipation slot 2, the fixing holes 8 around it are aligned with the pop-out holes 102. At the same time, another cooling fan body 4 is inserted into the heat dissipation slot 2. The limiting groove 3 prevents the cooling fan body 4 from falling off the surface of the heat dissipation slot 2. By pulling out the groove on the surface of the top rod plate 6 on one side of the mounting box 1, the top rod plate 6 is pulled out from the upper surface of the slide plate bottom plate 101. The inserting top rod 104 and the linkage pull plate 103 pop out from the pop-out hole 102 under the action of the tension spring 105, and at the same time enter the fixing holes 8 around the surface of the cooling fan body 4 for fixation. This also prevents the cooling fan body 4 from sliding out of the opening end of the heat dissipation slot 2, thus realizing the quick installation of the cooling fan body 4. When it is necessary to reduce the number of cooling fan bodies 4, the fixing of the cooling fan body 4 is released by pulling the linkage pull plate 103, thus realizing the purpose of quick disassembly.

[0029] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
