The handle is equipped with 2 and installs in the heat dissipation cold drawing front portion of module, and the handle passes through the screw to be fixed with heat dissipation cold drawing, realizes the quick plug of module.

The surface design of module apron has subtracts heavy decoration groove and data plate mounting groove, through the shielding rubber ring cooperation with heat dissipation cold drawing and connector, makes whole module form inclosed whole.

The module mainboard adopts a domestic processor and a display chip, the maximum power consumption of the whole board is about 70W, the heat of the chip is conducted to the sunflower type fins through the heat conducting pad, the heat radiating boss and the cold plate substrate, and the heat of the fins is taken away in a forced convection heat exchange mode through an external fan, so that the normal work of the module at high temperature is realized.

The utility model has the advantages that

The block adopts LRM framework design, is convenient for quick assembly disassembly and maintenance, and is small in size, light in weight, excellent in vibration impact resistance, high and low temperature resistance and mould salt spray performance, and suitable for various severe working environments. Through the heat dissipation design, the heat of the main heating device on the whole mainboard can be intensively conducted to the fin area, and the heat is taken away through the external fan, so that the reliability of the equipment is ensured.
