Description

Technical Field

[0001] The utility model relates to the technical field of three-phase diodes, and more specifically, to a three-phase diode rectifier bridge module. Background Art

[0002] The three-phase diode rectifier bridge switch module is a device made of six ultra-fast recovery diode chips and a high-power high-voltage thyristor chip connected according to a certain circuit and then encapsulated in a PP housing. Achieving efficient heat dissipation of the rectifier bridge module is the key to ensuring its stable operation and extending its service life.

[0003] The insulating thermal conductive material of the existing mechanism conducts the heat inside the shell to dissipate heat, which is natural heat dissipation. This heat dissipation method will cause slow heat dissipation of the thermal conductive sheet and difficulty in heat dissipation inside the three-phase diode rectifier bridge module in places with high outdoor temperatures.

[0004] After searching, the Chinese patent with authorization announcement number CN218039176U discloses a three-phase diode rectifier bridge module. This structure is fixedly connected to the inside of the three-phase rectifier module through a thermally conductive ceramic plate, thereby conducting heat from the inside of the three-phase rectifier module, and conducting heat from the bottom of the thermally conductive ceramic plate through the heat sink. Since there is a gap between the mounting base and the bottom of the protective shell, air can easily enter and take away the heat from the surface of the heat sink for natural heat dissipation and cooling. The semiconductor radiator is opened to cool the outer end of the thermally conductive ceramic plate. The semiconductor radiator is small in size and cools quickly. The low temperature is introduced into the interior of the three-phase rectifier module through the thermally conductive ceramic plate to reduce the internal heat of the three-phase rectifier module. The entire device is installed and fixed through the mounting base. The connecting line is connected to the three-phase rectifier module through a sealing ring, so that the upper end of the protective shell is sealed, and the three-phase rectifier module is waterproof, dustproof and circuit protected by the protective shell.

[0005] However, in actual use, this structure uses a thermally conductive ceramic plate to conduct heat from the bottom of the three-phase rectifier module, and uses a semiconductor radiator to cool and cool the outer end of the thermally conductive ceramic plate to perform heat dissipation. As a result, only local heat dissipation can be performed, making it difficult to dissipate heat around the three-phase rectifier module, thereby affecting the overall heat dissipation effect.
