Description

  The present invention relates to a snow melting device.

  Conventionally, a snowmelting device generally uses a watering method of pumping up groundwater and spraying it, but this method is not suitable for an area with little groundwater because there is concern about ground subsidence due to the depletion of groundwater.

  Therefore, for example, a snow melting device using a heat pipe as disclosed in Japanese Utility Model Laid-Open No. 6-40007 (hereinafter referred to as a conventional example) has been proposed. The heat pipe is a pipe made of a material having high thermal conductivity, in which a volatile liquid is sealed, and moves heat generated at one end of the pipe to the other end.

  In the conventional example, one end of the heat pipe is disposed in a side groove such as a roadside, and the other end is disposed below a snow melting portion such as a road. The heat is taken out from the heat, and the heat is moved to the other end to dissipate heat at the portion where the snow is melted, so that the snow is melted.

  Therefore, the conventional example does not pump up groundwater, so it is suitable for areas with little groundwater, and because it has a structure that requires a heat source for the water flowing in the gutters, for example, a snow melting device that uses geothermal heat. There is little effort to dig deep into the soil, and workability is good.
