Embodiment 1
[0039] see figure 1 , 2 , 4. The present invention provides a technical solution: a DC / DC power module overheating protection device, which specifically includes:
[0040] Power embedded mechanism 1, the power embedded mechanism 1 has a square body, and a protection mechanism 2 installed on the outer surface of the square body, and a cross bracket 3 installed on the top of the protection mechanism 2, through the design of the protection mechanism 2 to provide initial It is inevitable that the power module will be in direct contact with the air, reducing the rate of self-oxidation caused by the heat generated by the power module during use, and prolonging the service life of the power module. And installation, while carrying out initial dust blocking, reducing the contact rate of dust and equipment, the power embedded mechanism 1 includes:
[0041] Embedding block 11, the embedding block 11 has a square cylinder, and an embedding groove 12 provided on the top of the square cy...
Embodiment 2
[0050] see Figure 1-4 , on the basis of Embodiment 1, the present invention provides a technical solution: the fixing mechanism 13 includes a threaded spherical plate 131, and a heat dissipation through hole 132 opened on the top of the threaded spherical plate 131, and a poly The flow ball panel 133, and the ventilation hole 134 opened on the inner surface of the flow ball panel 133. The power module is installed and fixed through the design of the threaded spherical plate 131. At the same time, its own spherical structure evenly disperses the external pressure to avoid damage to the power module caused by stress concentration. The power module is continuously protected, and the fixed position makes the power module It fits more closely with the equipment and integrates the structure to avoid misalignment and wear.
[0051] The outer surface of the threaded ball plate 131 is installed on the inner surface of the embedded block 11, and the threaded ball plate 131 and the con...
Embodiment 3
[0054] see Figure 1-5 , on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the position adjustment mechanism 23 includes:
[0055] The heat conduction plate 231, the heat conduction plate 231 has a spherical disc body, and a thermal expansion column 232 installed in the middle of the spherical disc body, and a limit strut 233 installed at the bottom of the spherical disc body and outside the thermal expansion column 232, and installed in the limit The correction rod 234 at the other end of the support rod 233, and the frustum block 235 installed at the bottom of the correction rod 234. Driven by the self-heating of the power module, changing the airflow path, distributing the airflow through the bottom of the protective case 21, increasing the flow rate of the airflow, increasing the rate of cooling and heat dissipation, and assisting the airflow to clean the surface of the installation mechanism of the power module. Avoid cir...
