Patent Document 1: Japanese Patent Application Publication No. 2014-199208

The sensor assembly including the sensor of the detection device of the transportation route equipment is installed on the outer surface of the detection vehicle and moves together with the detection vehicle. For example, a detection device that detects the shape and position of the track, and the sensing component is installed on the bogie of the detection vehicle. Therefore, the sensing component will endure a large amount of vibration when the vehicle is being detected, and it is necessary to mitigate the impact of the vibration when the vehicle is being detected by various means. In addition, although the sensor itself generates heat during operation, it is greatly accelerated by detecting the vibration of the vehicle during driving, and it is impossible to install an air cooling fan. And because the sensing components are installed on the outer surface of the detection vehicle, they will be affected by the surrounding environment where the rails are laid. For example, the sensing components of detection devices used in high-temperature regions such as the Middle East and Southeast Asia are required to be in a high temperature environment above 50°C Under normal operation. However, most sensors are not designed to operate in such a high-temperature environment, and must have a cooling structure that includes the sensing components of the sensor.

The subject of the present invention is to provide a cooling structure for an induction component of a detection device for transportation equipment, which can absorb and detect vibrations when the vehicle is running, and has a cooling mechanism.

In addition, the method for cooling an induction component of a detection device of a transportation equipment of the present invention includes the following steps: storing an induction component including an inductor of a detection device of the transportation equipment in a cooling shell; and using the cooling shell for cooling A cooling element of the induction assembly is connected by a connecting mechanism with an elastic body between the connecting mechanism and the cooling shell; the cooling shell, the cooling element and the connecting mechanism are sealed in a closed container; and The airtight container is arranged on the detection vehicle of the transportation equipment, wherein the elastic body absorbs the vibration of the detection vehicle during driving without transmitting the vibration of the detection vehicle during driving to the cooling shell and the cooling element. The heat of the component is conducted from the cooling shell to the cooling element through the connecting mechanism, and the heat of the cooling element is conducted to the airtight container and discharged from the airtight container to the outside.

Since the cooling shell and the cooling element used to cool the sensing assembly are connected by a connecting mechanism, and an elastic body is provided between the connecting mechanism and the cooling shell, the vibration of the vehicle is detected by the elastic body of the connecting mechanism. absorb. In addition, since the heat of the induction component is transferred from the cooling shell to the cooling element through the connecting mechanism, the heat of the cooling element is transferred to the airtight container and discharged to the outside from the airtight container, so a cooling structure of the induction unit can be provided, which can absorb and detect Vibration when the vehicle is running, and has a cooling mechanism.

Furthermore, in the sensor element cooling device of the detection device of the transportation equipment of the present invention, the cooling element is composed of Peltier elements.

And the transportation device of the present invention The method for cooling the induction component of the prepared detection device further includes a heat insulating material, and the heat insulating material is arranged between the cooling shell and the airtight container. Since the function of the cooling element is to make the heat generated by the induction component move to the airtight container through the cooling shell, the total heat, together with the heat generated by the operation of the cooling element itself, is released from the airtight container to the outside. At this time, the airtight container The temperature is higher than the cooling shell. In this regard, by inserting a heat insulating material between the cooling shell and the airtight container, the heat insulating material can prevent the heat conducted to the airtight container from being transferred back to the cooling shell, and can further exert its effect as a vibration control material and improve the shock resistance. .

Further, in the sensor element cooling device of the detection device of the transportation equipment of the present invention, the cooling shell and the connecting mechanism have a comb-shaped joint that engages with each other. In addition, in the method for cooling the induction component of the detection device of the transportation equipment of the present invention, the cooling shell and the connecting mechanism are provided with a comb-shaped joint that engages with each other.

Furthermore, the comb-shaped joints that mesh with each other are interposed with high-viscosity, high-heat-conductivity grease with high thermal conductivity and damping effect on vibration, and at the same time, the vibration damping effect and the high thermal conductivity effect are improved.

Furthermore, since the heat insulation material is arranged between the cooling shell and the airtight container, when the heat generated by the self-induction component is moved through the cooling shell to the airtight container by the cooling element, the heat insulation material can minimize the heat conduction from the airtight container Cool the shell back.

Furthermore, since the cooling shell and the connecting mechanism are provided with comb-shaped joints that mesh with each other, the contact area between the cooling shell and the connecting mechanism becomes larger, and the heat transfer from the cooling shell to the connecting mechanism can be promoted.
