Description

Technical Field

[0001] The utility model relates to the technical field of ignition coils, and more specifically, to an ignition coil with a heat dissipation bracket. Background Art

[0002] In the existing technology, in the existing ignition coil design, there is often no effective heat dissipation mechanism. Since the ignition coil generates a lot of heat during operation, if there is no appropriate heat dissipation measure, it will cause its temperature to rise, which may affect its performance and life. Therefore, the lack of a heat dissipation mechanism has become a problem that needs to be solved in the existing ignition coil design.

[0003] In some existing ignition coil designs, although the importance of the heat dissipation mechanism has been recognized, the structural limitations of the ignition coil make it inconvenient to install the heat dissipation mechanism. This is usually because the ignition coil has a compact structure and limited internal space, making it difficult to integrate sufficient heat dissipation area in it, which also brings difficulties to the installation of the heat dissipation mechanism.

[0004] In some existing ignition coil designs, although heat dissipation mechanisms are provided, the installation methods of these heat dissipation mechanisms are often complicated and require multiple steps of assembly and adjustment, which is not only time-consuming but also increases the possibility of failure. In addition, these heat dissipation mechanisms are usually not able to be disassembled quickly, which will cause great inconvenience once maintenance or replacement is required.

The top end of the cross 10 is slidably installed in the slide groove 14 and the outer end is fixedly connected to the control sleeve 11.

[0035] A gasket 16 is provided between the plug pin 3 and the ignition coil body 1 , and the gasket 16 prevents the bottom end of the plug pin 3 from directly contacting the ignition coil body 1 , thereby preventing damage to the ignition coil body 1 .

[0036] A heat dissipation mechanism is arranged on the heat dissipation bracket 2, and the heat dissipation mechanism includes a heat sink 17, a thermal pad 18, a back cover 19 and a heat dissipation fan 20. The heat sink 17 is arranged on the heat dissipation bracket 2, the thermal pad 18 is arranged on the ignition coil body 1, and the back cover 19 is arranged on the heat dissipation bracket 2.

The two groups of heat dissipation fans 20 are started, and the two groups of heat dissipation fans 20 blow and inhale the back cover 19 respectively, so that continuous air circulation is carried out in the back cover 19, and the temperature adsorbed by the thermal pad 18 can be blown away, thereby improving the heat dissipation efficiency and helping to maintain the normal working temperature of the ignition coil.

[0037] There are multiple groups of heat sinks 17, and the multiple groups of heat sinks 17 are arranged in sequence and installed on the heat sink bracket 2. The multiple groups of heat sinks 17 are arranged in sequence and installed, which increases the heat dissipation area and improves the heat dissipation efficiency.

[0038] In this embodiment, when installing the heat dissipation bracket 2, the plug 3 is inserted into the ignition coil body 1 and the heat dissipation bracket 2, and then the fixing cover 6 is buckled on the plug 4 set at the top of the plug 3, and the fixing cover 6 is rotated so that the bottom end of the cross 10 moves to match the cross groove 9 set at the top of the plug 4, and the plug 4 can be inserted into the fixing cover 6. By setting the top sheet 7 as an elastic sheet, the top sheet 7 is lifted up by the plug 4, and when the top sheet 7 moves to the top groove 5 position, it is reset, so that the top sheet 7 is stuck in the top groove 5, and then the bottom end of the fixing cover 6 can be fixed on the heat dissipation bracket 2. The end faces are aligned for quick installation. When the heat dissipation bracket 2 needs to be disassembled, the control sleeve 11 is pulled upward to drive the top end of the cross 10 to slide along the slide groove 14, so that the bottom end of the cross 10 drives the top sleeve 8 to slide upward. When the top end of the top sleeve 8 hits the top sheet 7, the top sheet 7 is pushed out of the slot, thereby releasing the card connection of the slot, and the fixed cover 6 can be removed from the plug 4. When the top sleeve 8 slides upward, the bottom end slides along the limit rod 12, and the spring 13 is squeezed by the bottom end of the top sleeve 8. When the control sleeve 11 is released, the elastic recovery of the spring 13 pushes the top sleeve 8 to reset.

[0039] See also Figure 1 As an implementation method of an ignition coil with a heat dissipation bracket for the heat dissipation mechanism: a heat dissipation mechanism is arranged on the heat dissipation bracket 2, and the heat dissipation mechanism includes a heat sink 17, a thermal pad 18, a rear cover 19 and a heat dissipation fan 20. The heat sink 17 is arranged on the heat dissipation bracket 2, the thermal pad 18 is arranged on the ignition coil body 1, the rear cover 19 is arranged on the heat dissipation bracket 2, and two groups of heat dissipation fans 20 are respectively installed on both sides of the rear cover 19.

[0040] There are multiple groups of heat sinks 17 , and the multiple groups of heat sinks 17 are arranged in sequence and mounted on the heat sink bracket 2 .

[0041] More specifically, the heat of the ignition coil is absorbed by the thermal pad 18, and two groups of cooling fans 20 are started. The two groups of cooling fans 20 blow and suck air into the rear cover 19 respectively, so that continuous air circulation is achieved in the rear cover 19, which can dissipate the temperature absorbed by the thermal pad 18 and further dissipate the heat through multiple groups of heat sinks 17.

[0042] In summary, when the overall device is in use or running: when installing the heat dissipation bracket 2, the pin 3 is fully inserted into the ignition coil body 1 and the heat dissipation bracket 2, and then the fixing cover 6 is buckled on the plug 4 set at the top of the pin 3, and the fixing cover 6 is rotated so that the bottom end of the cross 10 moves to match the cross groove 9 set at the top of the plug 4, and the plug 4 can be inserted into the fixing cover 6, and the top sheet 7 is set as an elastic sheet, and the top sheet 7 is lifted up by the plug 4, and when the top sheet 7 moves to the top groove 5 position, it is reset, so that the top sheet 7 is stuck in the top groove 5, and then the bottom end of the fixing cover 6 can be fixed on the heat dissipation bracket 2. The end faces of the heat bracket 2 are aligned for quick installation. When the heat dissipation bracket 2 needs to be disassembled, the control sleeve 11 is pulled upward to drive the top end of the cross 10 to slide along the slide groove 14, so that the bottom end of the cross 10 drives the top sleeve 8 to slide upward. When the top end of the top sleeve 8 hits the top sheet 7, the top sheet 7 is pushed out of the slot, thereby releasing the card connection of the slot, and the fixed cover 6 can be removed from the plug 4. When the top sleeve 8 slides upward, the bottom end slides along the limit rod 12, and the spring 13 is squeezed by the bottom end of the top sleeve 8. When the control sleeve 11 is released, the elastic recovery of the spring 13 pushes the top sleeve 8 to reset.

[0043] The heat of the ignition coil is absorbed by the thermal pad 18, and two sets of cooling fans are started. The two sets of cooling fans 20 blow and suck air into the rear cover 19 respectively, so that continuous air circulation is achieved in the rear cover 19, which can dissipate the temperature absorbed by the thermal pad 18 and further dissipate the heat through multiple sets of heat sinks 17.

[0044] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
