The heat exchanger using frictional heat according to the present invention includes a heat exchange chamber 100 having a predetermined size having an internal space, and in one side, a circulation path for circulating the supply water introduced from the outside for heating the supply water. 270 is formed, and the other side of the hot water heating furnace 200 is formed with a friction surface for heating the feed water due to the frictional heat, the friction surface of the hot water heating furnace to circulate the circulation path with the frictional heat generated here It comprises a friction means 300 for heating the feed water and a drive means 400 for rotating the friction means.

The heat exchange chamber 100 is a chamber of a predetermined size having a space formed therein, and may be provided with an alloy material such as aluminum or stainless steel for accommodating the heat exchanger according to the present invention. The heat exchange chamber 100 may correspond to an outer cover for protecting the heat exchanger.

The hot water heating furnace 200 is located inside the heat exchange chamber and serves to heat the feed water introduced from the outside by frictional heat. Here, the supply water may be preferably heating water for heating, and various liquid (specific chemicals, oil, etc.) materials may be heated through the heat exchanger according to the present invention without being limited to the supply water term. .

The hot water heating furnace preferably has an approximately circular shape, and one side is formed with a circulation path 270 that can be circulated while heating the supply water, and the other side generates friction heat while rubbing with the friction member 310 to be described later. A planar friction surface 201 is formed.

In addition, a structure (unsigned) for fixing the hot water heating furnace to the structure or assembling the front cover 210 and the rear cover 220 to be described later is formed along the edge. The front cover 210 is coupled to the surface on which the circulation path is formed, and the rear cover is coupled to cover the friction member. Therefore, the friction surface 201 and the circulation path 270 are positioned inside each cover. At this time, each cover is assembled to the structure formed on the edge of the heating furnace by the fastening means.

In this case, the front cover has a groove (unsign) corresponding to the partition wall (unsign) forming a circulation path, so that the front cover is tightly coupled to cover the side of the circulation path to prevent leakage of the supply water.

On the other hand, the hot water heating furnace is formed with two circulation paths for heating two kinds of supply water, one of which is for heating the first supply water (water supply), the other is already the primary heating process It refers to the supply water heated to an arbitrary temperature after passing through. For example, when the heat exchanger according to the present invention is applied to a domestic boiler, the first circulation line will be supplied with hot water supply, which requires a lot of heating, and the second circulation furnace will be heated and the heating water supplied for heating supply will be introduced.

To this end, the inlet and the inlet for the four feed water inlet / outlet is formed in the hot water heater and the front cover, first, the inlet 230 for the feed water inlet is formed and discharged Discharge port 240 for the purpose is formed on one side of the front cover.

To describe this in more detail, first, the circulation path 270 is formed with a circulation path to circulate directionally with respect to the area of one side of the hot water heating furnace, and the water introduced through the supply water inlet 230 is first supplied. Heated while being circulated through the circulation path, the heated water is discharged through the outlet 240 formed in the front cover.

In addition, since the feed water introduced through the second feed water inlet 250 flows back into the hot water heating furnace in a state of rising to a predetermined temperature for heating, for example, a predetermined area is not circulated. Only the innermost circumference) is circulated and heated and then discharged through the outlet 260.

Inlet and outlet of this configuration is connected to the external power supply pipe (heating pipe, water pipe) and the like is made heat exchange.

Therefore, two circulation paths are formed in the circulation path 270 formed in the hot water heating furnace 200, and inlets and outlets are formed in each circulation path, respectively.

Meanwhile, the heating wire 280 and the temperature sensor 290 may be installed in the circulation path so that the temperature of the feed water may be increased more rapidly along with the temperature heating due to the frictional heat.

When the temperature of the supply water is checked from the temperature sensor 290 and is measured to be lower than the set temperature, the hot wire 280 is operated to heat the water temperature faster. At this time, the installation position of the temperature sensor is installed in the inlet (230, 250) or the heating water inlet 250 to compensate for the increase in temperature through the heating wire when the heat loss of the heating water is large in consideration of the heating possible temperature due to frictional heat. The heating wire and the temperature sensor can be easily configured by those skilled in the art by establishing a control environment through a separate control unit (not shown), and a detailed description thereof will be omitted.
