Chassis with radiation structure for protecting measurement and control device on electric railway

The invention provides a chassis with a radiation structure for protecting a measurement and control device on electric railway. The chassis comprises a front panel, a chassis body, a power supply module and a function module, wherein the front panel is connected to the front side of the chassis body, and the power supply module and the function module are inserted in the back side of the chassisbody. The chassis is characterized in that the power supply module contains a switch power supply, and holes are formed on the switch power supply; heat pipes are fixed on the chassis body, and are inserted into the holes of the switch power supply, so that the inner wall of the switch power supply hole can be contacted with the outer wall of the heat pipe. The chassis has the advantages that: compared with the traditional fan cooling mode, the radiating scheme has no noise and reliable performance, and the chassis is completely closed thereby avoiding invasion of dust.
