Abstract

An external cooling device with a back clip for automatic monitoring of a DTU includes a flexible back clip assembly, a cooling plate, and a cooling fan assembly. The flexible back clip assembly includes a flexible clamping plate and a heat dissipation mounting plate. Two flexible clamping plates are respectively set on both sides of the heat dissipation mounting plate by springs. The flexible back clip assembly is connected and fixed to the DTU device through the flexible clamping plates. The cooling plate is installed on a heat transfer window on the heat dissipation mounting plate, with the cooling surface of the cooling plate in close contact with the outer surface of the DTU device. The cooling fan assembly includes a heat dissipation plate, a cooling fan, and a heat dissipation shroud. The bottom surface of the heat dissipation plate is in contact with the heating surface of the cooling plate, the heat dissipation shroud is placed over the heat dissipation plate, and the cooling fan is installed inside the heat dissipation shroud. A backup battery is also included. The heat dissipation plate is also provided with several heat-conducting pillars and heat dissipation pins. This invention has good heat dissipation effect, stronger adaptability to high temperature and high heat environments, adaptive clamping force to adapt to different specifications of DTUs, and convenient and quick installation, clamping, and disassembly without affecting the normal operation of the DTU.
