Railway equipment inspecting and measuring apparatus, and railway equipment inspecting and measuring method
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.
1. A railway equipment inspecting and measuring apparatus, wherein said apparatus comprising:
a heat insulating case that forms a first space between itself and a control unit of said apparatus inspecting and measuring an inspection object, and seals the periphery of said control unit with heat insulating materials,
a cover that forms a second space between itself and said heat insulating case by covering said heat insulating case with itself, and
a temperature adjustment unit provided in the area across said first and second spaces, which has a heat exchange element, wherein:
the surface of said cover is coated with a heat-resistant coating, and said cover has a suction port that sucks the air from outside into said second space and an exhaust port that discharges the air from inside of said second space to the outside, and
said temperature adjustment unit has heat conduction members that conduct heat between the air in said first and second spaces and said heat exchange element, and a first fan transfers the air in the first space and a second fan transfers air in the second space, and
said control unit is installed on a rooftop of a passenger car.
2. The railway equipment inspecting and measuring apparatus as claimed in claim 1 , wherein:
said cover has ventilation holes on the front surface and rear surface in the running direction of said passenger car, and
said ventilation holes on the front surface of said cover in the running direction suck the air from outside of said cover into said second space when said passenger car is running.
3. The railway equipment inspecting and measuring apparatus as claimed in claim 1 , wherein:
said heat insulating case has a rack, which is based for mounting said control unit, and has an opening in its mounting surface,
said temperature adjustment unit has a first heat conduction member provided inside said first space, a first fan provided inside said first space, a second heat conduction member provided inside said second space, and a second fan provided inside said second space, and
said first fan is provided below said rack, and circulates the air inside said first space from below said control unit through said opening to above said control unit.
4. The railway equipment inspecting and measuring apparatus as claimed in claim 3 , wherein:
said cover has ventilation holes on the front surface and rear surface in the running direction of said passenger car, and
said ventilation holes on the front surface of said cover in the running direction suck the air from outside of said cover into said second space when said passenger car is running.
5. The railway equipment inspecting and measuring apparatus as claimed in claim 1 , wherein:
said heat exchange element is made of a Peltier device.
6. The railway equipment inspecting and measuring apparatus as claimed in claim 3 , wherein:
said heat exchange element is made of a Peltier device.
7. The railway equipment inspecting and measuring apparatus as claimed in claim 4 , wherein:
said heat exchange element is made of a Peltier device.
