Title:
SENSOR PROTECTING CASE, IMAGING DEVICE, WELDING SYSTEM, COOLING METHOD FOR SENSOR, AND COOLING CONTROL METHOD FOR SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/074982
Kind Code:
A1
Abstract:
The present invention provides a sensor protecting case capable of locally cooling a sensor input portion close to a welding heat source, and effectively cooling even a sensor main body. A sensor protecting case (30) is provided with a case main body (33) for housing a sensor main body (21) and a sensor input portion (22), and a centralized cooling portion (35) that is partitioned off by a partition (34) so as to include at least part of the sensor input portion (22), and constitutes an independent space within the case main body (33). The case main body (33) has a first gas inflow port (37) for causing gas G to flow into the case main body (33), and a first gas outflow port (38) for causing the gas G to flow out of the case main body (33). The partition has a second gas inflow port (39) that is connected to the first gas inflow port (37) in order to cause the gas G to flow into the centralized cooling portion (35), and a second gas outflow port (40) for causing the gas G to flow out of the centralized cooling part (35) into the case main body (33).
