[0028] [First Embodiment]

[0029] Refer to Figures 1-4 As shown, a combined heat dissipation plate provided by the first embodiment of the present utility model is as Figure 1As shown in the figure, it includes a first bottom plate 1 and a second bottom plate 5. A number of first heat dissipation fins 4 are provided on the top of the first bottom plate 1, and a number of second heat dissipation fins 6 are provided on the top of the second bottom plate 5. The first bottom plate 1 and the second bottom plate 5 are fixedly connected through a combination device 2. By setting the combination device, the first bottom plate and the second bottom plate are fixedly connected through the combination device, so that the first bottom plate and the second bottom plate can be quickly combined and fixed together, thereby changing the overall size of the heat dissipation plate. Through the modular combination method, the combined heat dissipation plate can meet the heat dissipation installation requirements at different positions in the vehicle, thereby further expanding the applicable range of the heat dissipation plate.

[0030] As Figures 2-3 shown, the combination device 2 in this embodiment includes a fixed block 21 fixedly connected to the first bottom plate 1 and a combination plate 24 fixedly connected to the second bottom plate 5. A through hole 22 is formed inside the fixed block 21, and the combination plate 24 is inserted into the inside of the through hole 22 and is in corresponding plug-in fit with it. A bolt 23 is also inserted inside the fixed block 21 and the combination plate 24, and the fixed block 21 is fixed inside the combination plate 24 through the bolt 23.

[0031] Preferably, as Figure 3 shown, a groove 28 is formed on the outer side of the end of the bolt 23 in this embodiment, and the groove 28 is a cross groove. By selecting the cross groove for the groove 28, the operator can more easily rotate the bolt with the help of tools such as a cross wrench; a number of anti-slip blocks 26 are fixed on the outer edge of the end of the bolt 23, and the anti-slip blocks 26 are arranged at equal intervals on the outer edge of the end of the bolt 23. By using the anti-slip blocks, the friction between the bolt and the operator is increased, making it easier for the operator to rotate the bolt; a trapezoidal block 27 is fixed on the side of the combination plate 24 away from the second bottom plate 5, and the size of the side of the trapezoidal block 27 away from the combination plate 24 is smaller than the side close to the combination plate 24. By using the trapezoidal block, the size of the side of the combination plate entering the fixed block 21 is reduced, making it easier for the combination plate to be inserted into the through hole inside the fixed block; a gasket 25 is arranged between the inner side of the end of the bolt 23 and the outer side of the fixed block 21. By using the gasket, the contact area between the bolt and the fixed block is increased, making the bolt fix the combination plate more firmly. An installation groove 29 is formed on the outer side of the end of the fixed block 21, and the protection component 3 is fixedly connected to it through the installation groove 29.

[0032] As Figure 4 shown, protection components 3 are provided at both ends of the fixed block 21 in this embodiment. By setting the protection components, the internal combination device is shielded and protected, thereby reducing the possibility of damage to the combination device and further extending the service life of the combination device.

[0033] As Figure 4As shown in the figure, the protection component 3 in this embodiment includes a protection plate 32 and mounting parts 31 fixed on both sides of the protection plate 32. The mounting parts 31 are located inside the mounting groove 29 and are in plug-in fit with it. The bolt 23 is located inside the space formed by the protection plate 32 and the mounting parts 31. Preferably, the cross-sections of the mounting groove 29 and the mounting parts 31 are arranged in a T-shape that matches each other, so as to ensure the positioning stability of the mounting parts 31 inside the mounting groove 29. Rubber pads 33 are fixed at positions corresponding to the mounting groove 29 on both sides of the mounting parts 31. The size of the rubber pads 33 is adapted to the size of the mounting parts 31. By using the rubber pads, the friction between the protection plate and the fixing block is increased, so that the protection plate is not easily moved in the placement groove. A reinforcing plate 34 is fixed at the bent connection position between the protection plate 32 and the mounting parts 31. By using the reinforcing plate, the strength of the protection plate is increased to avoid the situation of the protection plate deforming under force.

[0034] The specific working process of this embodiment is as follows:

[0035] When using the heat dissipation plate, the first bottom plate 1 with the first heat dissipation fins 4 and the second bottom plate 5 with the second heat dissipation fins 6 are brought closer to each other. Then, the combined plate 24 on the second bottom plate 5 passes through the through hole 22 of the fixing block 21 fixed to the first bottom plate 1. Then, the bolt 23 is rotated so that the bolt 23 passes through the fixing block 21 and is fixed to the combined plate 24, and then the positions of the first bottom plate 1 and the second bottom plate 5 are quickly fixed. By setting the combined device, the first bottom plate and the second bottom plate are fixedly connected through the combined device, so that the first bottom plate and the second bottom plate can be quickly combined and fixed together, and then the overall size of the heat dissipation plate is changed. Through the modular combination method, the combined heat dissipation plate can meet the heat dissipation installation requirements at different positions in the vehicle, thus further expanding the application range of the heat dissipation plate.

[0036] When using the protection component 3, the side of the protection plate 32 with the rubber pads 33 is inserted into the mounting groove 29 on one side of the fixing block 21. Then, the position of the protection plate 32 is fixed by the friction between the mounting parts 31 and the mounting groove 29, and then the bolt 23 is shielded and protected by the protection plate 32. By using the protection component 3, the bolt 23 can be prevented from being damaged by external forces, thus extending the service life of the bolt 23.

[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
