  These snow-dissipating heat radiators (snow-dissipating panels) described in Patent Documents 1 to 4 are installed side by side along a railroad track over several kilometers and in some cases several tens of kilometers. At this time, it is desirable that adjacent snow-dissipating heatsinks be installed without gaps, but actually, for example, utility poles are installed at intervals of about 50 meters along the railroad tracks. It is necessary to install while detouring. Further, the interval between the utility poles is not a constant interval, and an error of, for example, several tens of centimeters to several meters occurs.

  That is, the snow-dissipating heat radiators described in Patent Documents 1 to 4 cannot be installed without any gap along the railroad track, and some gaps are necessarily generated. When the gap is large, there is a problem that the snow accumulated in the gap remains as unmelted without obtaining the snow-dissipating effect of the snow-dissipating radiator. Alternatively, there has been a problem in that since a snow-dissipating heat radiator having a size according to the interval between the utility poles must be prepared, the manufacturing cost increases and the installation period becomes longer.
