[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] Please see Figure 1-2 This utility model provides a technical solution: a cooling unit for an automatic protection system of a train, including a tank 1 and a top cover 2. The top cover 2 is connected to the tank 1 by screws. After the top cover 2 is installed, the tank 1 can match the top of the automatic protection system cabinet. An air outlet 3 is opened at the bottom of the tank 1. An axial flow fan 5 is fixedly installed in the tank 1. An air inlet 4 is opened in the top cover 2. An installation plate 6 is fixedly connected to the lower surface of the top cover 2. A filter screen 7 is placed in the installation plate 6. A vent hole 8 is opened at the bottom of the installation plate 6. The air outlet 3, the axial flow fan 5, the vent hole 8, and the air inlet 4 are vertically aligned to facilitate the flow of gas. A power module 9 and a display control board 11 are also fixedly installed in the tank 1. A light-transmitting hole 12 corresponding to the indicator light on the display control board 11 is opened on the front wall of the tank 1.

[0016] Furthermore, the top cover 2 has an opening 14, and the filter screen 7 is made of flexible material. When the filter screen 7 is deformed, it can be inserted into the mounting slot 6 through the opening 14 or pulled out from the mounting slot 6, making it easy to replace the filter screen 7.

[0017] Furthermore, an electrical connector 10 is installed on the front wall of the tank 1, and the power module 9 is electrically connected to the electrical connector 10. The voltage is converted through the power module 9. The display control board 11 is electrically connected to the power module 9, and the axial flow fan 5 is electrically connected to the display control board 11.

[0018] Furthermore, a handle 13 is installed on the front wall of the tank 1 to facilitate the removal of the cooling unit from the automatic protection system cabinet.
