Abstract
Effectively control the temperature of a control unit of a railway equipment inspecting and measuring apparatus, and install the control unit of the railway equipment inspecting and measuring on the roof of the passenger car. The first space is formed between the control unit and the heat insulating case. The second space is formed between the heat insulating case and the cover. In the first space, heat is conducted between the air in the first space and the heat exchange element by the first heat conducting member, and the first fan causes circulation of the air in the first space. In the second space, heat is conducted between the air in the second space and the heat exchange element by the second heat conducting member, and the air inside the second space is diffused by blowing the air from a suction port into the second space with the second fan.
