Disclosure of Invention
The utility model aims to provide a: the fixing structure of the water cooling plate with the good heat dissipation effect is provided, and the problem that in the prior art, the water cooling plate cannot be in direct contact with a circuit board, and then the heat dissipation effect of the circuit board is poor is solved.
In order to realize the purpose of the utility model, the utility model provides a following technical scheme:
a fixing structure of a water cooling plate comprises the water cooling plate and a first circuit board, wherein a stud is fixed on the water cooling plate through press riveting, a mounting hole is formed in the first circuit board and penetrates through the stud, and the first circuit board is pressed on the water cooling plate through a nut.
According to the technical scheme, the stud is directly fixed on the water cooling plate in a press riveting mode, the first circuit board is pressed on the water cooling plate by forming the mounting hole on the first circuit board and penetrating the mounting hole through the stud, and then screwing the stud into the first circuit board by using the nut matched with the stud; when first circuit board is fixed to this kind of mode for first circuit board and water cooling plate direct contact, so that the heat of first circuit board is easily taken away by the water cooling board, and then has improved the radiating effect of new energy automobile spare part.
Furthermore, the single side of the first circuit board is fixed through four stud and nut structures. The number of the studs is reasonably selected so as to better fix the first circuit board.
Furthermore, a liquid cooling runner is arranged in the water cooling plate, and the fixing position of the stud on the water cooling plate avoids the liquid cooling runner. The stud avoids the liquid cooling runner, the sealing performance of the liquid cooling runner is enhanced, the reliability of the liquid cooling runner is improved, and the durability of the water cooling plate is further improved.
Furthermore, still be fixed with the erection column through the pressure riveting mode on the water-cooling board, the tip of erection column is equipped with the internal thread, has the second circuit board through the bolt fastening on the erection column. The second circuit board is suspended above the water cooling plate through the mounting columns, so that the space above the water cooling plate is reasonably utilized, and the arrangement of electrical components is facilitated.
Furthermore, the second circuit board is square and four corners of the second circuit board are respectively connected with a mounting column. The second circuit board is fixed to four erection columns, and stability is high.
To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that: the method comprises the following steps that a stud is directly fixed on a water cooling plate in a press riveting mode, a mounting hole is formed in a first circuit board and penetrates through the stud, a nut matched with the stud is screwed in, and the first circuit board is pressed on the water cooling plate; when first circuit board is fixed to this kind of mode for first circuit board and water cooling plate direct contact, so that the heat of first circuit board is easily taken away by the water cooling board, and then has improved the radiating effect of new energy automobile spare part.
