Abstract

PURPOSE:To provide a heat exchanger that does not utilize other energy sources at all than the water head by heating water that moves in a sealed chamber only by means of torque which is obtained from the water head. CONSTITUTION:A rotary shaft 6 disposed in the center of a sealed heat generator 20 is rotated by the torque that is obtained from the water head in order to generate heat in a sealed chamber by agitating oil filled in it. The water that is branched from the same water head and enters into the chamber from the end of a water feed pipe 18 is heated by the heat of agitation of said oil while it passes from the bottom of the chamber through a long spiral water conduit 3 to an opening in the top. The water then passes through a temperature regulative valve 19a to be supplied to a hot water reservoir tank 21 via a hot water pipe 19.

Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a heat exchange device for producing hot water using heat of stirring.

b. Conventional technology Conventionally, in order to make six streams of water hot, it was first necessary to heat the water, and each step was required to heat the water using firewood or heavy oil (or heat it with electricity). In addition to the attached facilities, hot water production always involved a consumable energy source.

C1 Purpose of the Invention The main purpose of the present invention is to heat filtrate transferred within a closed room using only rotational force, and the rotational force is usually obtained from the head of the water without using any other energy source. The purpose of the present invention is to provide a heat exchange device.

In particular, it is sufficient to use some of the wasted water to obtain rotational force, and use that rotational force to stir the highly viscous liquid at high speed in a sealed chamber, generate heat, and move it within the sealed chamber. The object of the present invention is to provide a heat exchange device that moderately heats the water used to heat the water to make it hot water.

d1 Structure of the Invention The structure of the present invention will be explained with reference to the drawings. A water pipe 11 passing through the main water drop is led to an arbitrary rotating machine 12, an IJF water pipe 13 is installed below the rotating machine 12, and the rotation driving shaft 1
A pulley 15 attached to the end of the closed heat generator 20 is connected to a pulley 16 at the end of the closed heat generator 20 by a V-belt 17.

The tip of the water supply pipe 18 branching from the middle of the water pipe 11 is connected to a hot water storage tank 21 where the hot water, which is circulated spirally in the room of the wire machine from the lower part of the heating pipe 20 and guided from the upper temperature pipe 19, is placed in a hot water tank 21 installed in advance. The hot water is stored in the hot water pipes 22 and supplied to the required areas when needed.Eight pipes are each equipped with open cocks 11a, 18a, and 22a, and the hot water pipe 19 is equipped with the necessary hot water pipes. A temperature control valve 19a is installed to automatically adjust the temperature by setting it to the bush temperature.

However, as can be clearly seen in the cross-sectional view of Figure 2, the sealed heat generating body 1120 has an outer surface of the heat conducting body 2 made of a good heat conductor such as aluminum or copper alloy, and is covered with a heat insulating material such as glass wool, asbestos gypsum, or foamed resin. 1, a water passage groove 3 communicating with the upper and lower openings is spirally formed on the inner surface of the main body 2, and a heat conductive inner wall made of a good thermal conductor like the main body 2 is provided on the inner surface of the main body 2. 4 is stretched to ensure a water flow path for the water flow groove 3, and the main body 2 has a heat insulating coating 1 on the outer surface and a heat conductive inner wall 4 on the inner surface.
It is installed so as to be fixed on the foot stand.

A rotor 8 is fixed by a key 6a on the axis of a rotating shaft 6 passing through the center of this hermetic heating machine 20, and oil holes 9 are formed in the rotor 8 in a radial manner to flow from the center to the rotating circumferential surface. Rotor 8 and heat conduction inside g! The gap between the rotating shaft 6 and the heat-conducting inner wall 4 is an oil chamber 10, which is mainly filled with mineral oil. The water that enters from the water supply 1g18 connected to the lower opening of the sealed heat generator 20 passes through the spiral water passage groove 3 inside the machine and enters the upper opening. The hot water then flows into the hot water pipe 19 connected thereto, and is eventually stored in the hot water storage tank 21.

00 Effect The present invention rotates the rotary shaft 6 installed at the center of the closed heat generating machine 20 using the rotational force obtained from the drop of water, and generates heat in the closed chamber by stirring the oil filled inside, which is then transferred to the same water. Water supply pipe 18 branched to obtain water from the head
The water enters the sealed chamber from the tip of the oil, and the water flows from the bottom of the chamber through the water passage groove 3, which has a long spiral path, and reaches the opening at the top. It is heated, passes through a temperature control valve 19a, and is sent to a hot water storage tank 21 via a hot water pipe 19.

0 Effects of the Invention The present invention utilizes the principle that when a highly viscous liquid is stirred at high speed in a completely sealed chamber, heat is generated due to repeated violent collisions and friction between oil molecules, and the stirring driving force and water supply are combined. This system heats water obtained from the same water stream and moves inside a closed heat generating machine, and not only does this heat exchange process economically, it also has the effect of constantly storing hot water in a hot water storage tank and using it as desired. be.
