Description

[Detailed explanation of the idea] [Industrial application field] This proposal relates to a snow melting device.

[Prior Art] Conventionally, this type of device is as follows.

1 Using the water tank method, water was stored in the snow melting layer, the water was heated, and snow was added to melt the snow.

2 After heat exchange, excess exhaust heat (heated water, steam, etc.) was blown out from the large-diameter exhaust port to the sides and bottom to partially melt the snow.

[Problems to be solved by the invention] The conventional techniques described above had the following problems.

1. Because it was melted by the surface heat of the metal in the heat generating part,
The heat conduction of metal is poor, and the surface metal easily gets cold.
It takes time and only the contact surface of the snow melts.

2. Since a large amount of water is stored and warmed up, it takes a long time initially and the operation at the end is troublesome.

3. Due to the large hole diameter, the distance that heat travels is short, the exhaust hole is easily clogged with snow, and the temperature of the exhaust heat is low.

The present application was made in view of the problems of the prior art, and its purpose is to provide a system that can do the following.

1 The total amount of heat generated by the heat source can be used for snow melting.

2. The small-diameter thermal injection pores allow high-temperature, high-speed heat to reach deep into the snow, making it highly effective in melting snow.
