Description

Technical Field

[0001] The utility model belongs to the technical field of distributor covers, and in particular relates to a distributor cover structure for an automobile. Background Art

[0002] The distributor is a component in the ignition system that controls the on and off of the primary circuit in a timely manner and distributes sparks to the spark plugs of each cylinder in sequence. The distributor is mainly used in traditional ignition systems and ordinary electronic ignition systems, and these two ignition systems have basically been eliminated.

[0003] According to the automobile distributor cover structure disclosed in patent No. CN202120038673.1, it includes a shell and a heat dissipation device, the upper surface of the shell is fixedly connected with a plug-in column, the heat dissipation device is arranged on the inner wall of the shell, and the heat dissipation device includes a mounting column, the side of the mounting column close to the plug-in column is fixedly connected to the shell, the inner wall of the mounting column is slidably connected with a dustproof plate, the inner wall of the mounting column is slidably connected with a fixing ring, the side of the fixing ring close to the mounting column is slidably connected with the dustproof plate, and the side of the fixing ring away from the mounting column is fixedly connected with a fixing bracket, and the number of fixing brackets is two.

[0004] The above scheme still has certain technical defects in actual use. Since the heat dissipation device is directly arranged on the cover body, the outside is directly connected to the inside of the cover body through the heat dissipation device. Although a dustproof plate is added, fine dust will still enter, causing accumulation and affecting the service life. Moreover, the heat dissipation method in the above scheme is relatively passive. Although it can play a role in heat dissipation, the heat dissipation efficiency is not high and is affected by the external environment. For this reason, we propose an automobile distributor cover structure. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution for the structure of an automobile distributor cover: it includes a shell 1, a heat-conducting box 2 and a cooling sheet 22. The heat-conducting boxes 2 are fixedly arranged on both sides of the exterior of the shell 1. A heat dissipation groove is arranged inside the heat-conducting box 2. A heat-conducting plate 21 in contact with the inner wall of the shell 1 is fixedly inlaid on the surface of the heat-conducting groove on one side close to the shell 1. A cooling sheet 22 is arranged on the other side of the heat-conducting plate 21. The heat-absorbing end of the cooling sheet 22 is fixedly connected to one side of the heat-conducting plate 21 through heat-conducting silicone grease. The heat-releasing end of the cooling sheet 22 is fixedly connected to a heat-dissipating fin 23 through heat-conducting silicone grease. The heat-dissipating fin 23 and the cooling sheet 22 are both arranged in the heat-dissipating groove. Heat transfer is performed through the heat-conducting plate 21, the cooling sheet 22 and the heat-dissipating fin 23 in the heat-conducting box 2, and the heat inside the shell 1 is transferred to the inside of the heat-conducting box 2, thereby achieving the purpose of cooling and dissipating the inside of the shell 1.

[0023] Specifically, an air inlet 24 and an air outlet 25 connected to the inside of the heat dissipation groove are respectively provided on both sides of the outside of the heat conduction box 2. A heat dissipation fan 27 is fixedly installed inside the air inlet 24 and the air outlet 25. A dustproof net 26 is fixedly installed outside the air inlet 24 and the air outlet 25. The heat dissipation fan 27 provided in the air inlet 24 and the air outlet 25 is used to ventilate and dissipate heat in the heat conduction box 2, and the heat dissipated by the heat dissipation fins 23 is discharged from the heat conduction box 2, thereby ensuring the stability of the internal temperature of the heat conduction box 2 so as to facilitate continuous heat transfer of the refrigeration plate.

[0024] Specifically, a heat conducting rod 221 is provided on the outside of the cooling fin 22. The heat conducting rod 221 is arranged around the outside of the cooling fin 22. Both sides of the heat conducting rod 221 are in close contact with the heat conducting plate 21 and the heat dissipating fins 23 respectively. The heat conducting rod 221 increases the contact area on both sides of the cooling fin 22, thereby achieving the purpose of improving the heat dissipation efficiency.

[0025] Specifically, a heat insulating layer 222 is fixedly provided between the heat conducting plate 21 and the heat dissipating fins 23. The refrigeration sheet 22 and the heat conducting rod 221 are both embedded in the heat insulating layer 222 and both sides extend to the outside of the heat insulating layer 222. The heat insulating layer 222 is provided to prevent the heat absorbing end of the refrigeration sheet 22 from being affected by the temperature environment in the heat conducting box 2, which would cause a decrease in the operating efficiency of the refrigeration sheet 22.

[0026] Specifically, a heat-conducting ring 14 is provided inside the shell 1, and the heat-conducting ring 14 is fixedly embedded in the inner wall surface of the shell 1. The heat-conducting plate 21 extends to one side of the inside of the shell 1 and is in close contact with the heat-conducting ring 14. The heat-conducting ring 14 replaces the heat-conducting plate 21 to contact the inside of the shell 1, thereby improving the efficiency of heat transfer.

[0027] Specifically, a plug post 13 is provided on the top of the shell 1 , and the plug post 13 is fixedly installed on the top of the shell 1 , and electrical connection with external components is achieved through the provided plug post 13 .

[0028] Specifically, mounting portions 12 are provided around the outer bottom of the shell 1 . The mounting portions 12 and the shell 1 are an integral structure. The mounting portions 12 are provided to achieve the installation of the shell 1 so that it can remain stable.

[0029] In the present embodiment, during use, the heat generated by the operation of the components inside the shell 1 is first absorbed by the heat conductive ring 14, and then transferred to the heat conductive plate 21, and the heat absorbing end of the refrigeration plate 22 is used to absorb the heat of the heat conductive plate 21, and then the heat releasing end of the refrigeration plate 22 is transferred to the heat dissipation fins 23. In this process, since the two sides of the heat conductive rod 221 are in close contact with the heat conductive plate 21 and the heat dissipation fins 23 respectively, the heat transfer effect is also played, thereby improving the efficiency of heat transfer. Finally, the heat dissipation fins 23 are used to quickly diffuse the heat into the heat dissipation groove in the heat conductive box 2, and then the heat dissipation fan 27 in the air inlet 24 draws outside air from the outside and injects it into the heat dissipation groove in the heat conductive box 2. At the same time, the heat dissipation fan 27 in the air outlet 25 draws high-calorie air from the heat dissipation groove and discharges it, so that a stable airflow is formed in the heat dissipation groove in the heat conductive box 2, thereby achieving the purpose of heat dissipation. Such a design can effectively avoid the entry of external dust while ensuring the heat dissipation efficiency, thereby ensuring the service life of the components inside the shell 1.
