[Industrial applications]

 The present invention is designed to improve the thermal efficiency of the radiating pipes on a durable snow melting machine for snow melting processing equipment that uses snow and snow collected during the winter period as electric power, gas, kerosene, etc. as heat sources and fuels. The present invention relates to a heat transfer thin plate for arranging and fixing.

[0002]

[Prior art]

 In northern regions, the amount of snowfall during the winter is so large that it causes various obstacles.Therefore, the relevant government agencies and the private sector are currently accounting for high costs and implementing snow removal measures. is there. The following is a method that has been conventionally used for removing snow. I. The snow blades installed on the snow plows raise the snow on the left and right sides of the pavement, or the snow is loaded on a truck and discarded at the designated snow removal location.

B. A pipe with an injection port is embedded underground in the paved road, and hot water or ground water is passed through the pipe to inject it. Alternatively, a method of enclosing the main body with a heat source in a box shape and throwing in snow from the top to melt it. C. A method in which a paved road surface in a downtown area such as the central area is called "road heating" and electric wires are placed on the ground below the road surface, covered with tile plates and passed through an electric current to radiate heat. The above-mentioned method is performed in the conventional technique.

[Problems to be solved by the device]

 As a conventional technical method, the above-mentioned a. ~ Ha. However, all have the following drawbacks. I. This method is often used in all municipalities, but various expenses such as personnel expenses are large, and in comparison to this, time efficiency is poor. B. In the area where the temperature at night is severe and low, the method does not utilize the function, the water supply is not perfect, and it freezes, which causes inconvenience to traffic. C. The above method is only for the special building and pavement with a lot of traffic as mentioned above, which is not a general one and the construction cost is high and the electric power cost is also high.

The present invention was devised in view of the above drawbacks, and was filed earlier, but it is a “snow melting treatment device using waste oil and kerosene” according to Utility Model Registration Application No. 54068 in 1987. Notification of new model No. 031305) The registration was assessed based on the registration No. 1963652. Depending on the application, the above-mentioned device also has the drawback that the effect is as described in the section of the above-mentioned subject. It is effective to use a heavy-duty snow melting machine with good durability on the pavement of a building through which large trucks carrying heavy objects are loaded and unloaded, or on the road surface of the bus garage where vehicles constantly run. The present invention provides a heat transfer thin plate which improves heat transfer by being connected to a heat radiating pipe arranged on the first layer of the durable snow melting disk A, has an excellent snow melting effect, and doubles endurance.

【Example】

 Examples will be described in detail with reference to the drawings. FIG. 1 is a perspective view of the above-mentioned Japanese Utility Model Application No. 62-054068 (utility model publication No. 031305 of 1992). The snow melting board 5 is heated by a boiler installed in the heat transfer device. What is mixed with antifreeze liquid is sent to the first layer of the snowmelt board by the antifreeze circulation pump.

[0007] In this layer, the snow melting board 5 is warmed through the heat dissipation pipe (out) 2A shown in the figure, which passes through the heat dissipation pipe (out) 2A that is laid in a meandering shape, and the circulation to the boiler through the pipe is repeated. Although it is a general snow melting device, it has a structure of a snow melting board that is effective only by using a truck loaded with heavy objects, a large bus garage, or a road surface that frequently comes and goes as described above. It was devised in view of the fact that the above-mentioned application is not satisfactory in that a snow melting machine that melts quickly and has durability against weight must be used.

If one example is described, as shown in FIG. 2, the upper surface is a surface finishing board 1A cemented to a thickness of about 2 cm, and radiating pipes 2, 2A are laid in a meandering shape in the center. However, the interval B between the pipes should be within 15 cm to enable snow melting quickly and effectively.

FIG. 4 is a front view of FIG. 5 taken along the direction of arrows B to B ′. As shown in the figure, it is formed into a semi-circular shape that is adhered to the heat radiating pipes 2 and 2A, and has a suitable width and thickness. ing. FIG. 5 is a view seen from the bottom surface in the direction of arrows A to A ′ in FIG. 4. As shown in the figure, there is a key groove 3A for press-fitting a penetrating key on the left and right of the center line of the width corresponding to the bottom plane of the heat transfer thin plate 1 and a key groove 4A penetrating also on the upper part of the center of the circle. The heat transfer thin plate 1 is adhered to the tubes 2 and 2A, and together with the key attached to the heat radiating tube, it is pressed into the key groove with a hammer or the like and fixed. The present invention is not limited to the above-mentioned snow melting machine, and even if it has another structure, it has an effect of quickly generating durability and snow melting degree on the road surface.
