Problems solved by technology
With the advancement of technology, the integration of products is getting higher and higher. In order to ensure the long-term stable operation of the system, this poses a challenge to the cooling solution of the power supply. The usual method is to add a fan near the power supply, and then open the ventilation on the chassis hole, the disadvantage of this approach is that the inside of the device is prone to dust

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.
Description
(1) Technical field: [0001] The invention belongs to the technical field of automation control, and in particular relates to a case of an electrified railway protection measurement and control device with a heat dissipation structure. (two) background technology: [0002] The electrified railway protection measurement and control device (hereinafter referred to as the protection measurement and control device) is an important product widely used in the field of automation control. With the advancement of technology, the integration of products is getting higher and higher. In order to ensure the long-term stable operation of the system, this poses a challenge to the cooling solution of the power supply. The usual method is to add a fan near the power supply, and then open the ventilation on the chassis The disadvantage of this approach is that dust is easy to enter inside the device. (3) Contents of the invention: [0003] The object of the present invention is to design ...
