For example, as shown in FIG. 4, the one described in JP-A-10-19287 can be mentioned. This heat exchange panel P

る。In the conventional heat exchange panel P, the volume of the filling portion 104 is increased to increase the heat radiation area in order to improve the heat transfer coefficient. A plurality of thresholds 107 are provided inside,
Furthermore, there is a problem in that the bottom portion 108 has a complicated structure in which an inclination is provided, and it takes time and effort to manufacture. The reason why such a complicated structure is required is that the vaporized heat exchange medium is liquefied at the place where the heat is radiated when the heat is radiated, and the liquefied heat exchange medium is not reduced to the U groove 106 as it is, so The heat exchange medium that comes into contact with the heat exchange medium decreases, and this decrease in heat exchange medium causes a decrease in the heat transfer coefficient. Therefore, it is necessary to adopt a structure in which the liquefied heat exchange medium easily moves to the heat source. Therefore, the liquefied heat exchange medium is transmitted through the plurality of thresholds 107, flows on the inclined bottom portion 108, and easily reaches the U groove 106.

When the heat exchange medium is liquefied, the heat exchanger absorbs heat and heat is transferred from the skin in contact with the heat exchanger. The outer plate absorbs heat from the whole substantially uniformly according to the specific heat of the metal. In addition, if necessary, the contact portion of the outer plate with which the outer tube of the heat exchanger comes into contact is formed on an arc surface along the outer periphery of the outer tube. The heat exchange body has a simple shape with a circular cross section, and the liquefied heat exchange medium moves on the inner wall surface so that heat can be exchanged cyclically. Accordingly, the contact area is larger than when the outer plate surface and the outer periphery are simply in contact with each other, so that the heat transfer efficiency can be improved.

Here, the case where the heat exchange panel P emits heat and the case where the heat exchange panel P absorbs heat will be described separately. A. When the heat exchange panel P emits heat, the heat source supplied to the heat supply pipe (heat transfer pipe 9) is hot water,
The inside of the outer tube 4 is filled with water as a heat exchange medium W so as to be liquefied at normal temperature and reduced pressure. The hot water supplied to the heat supply pipe has a temperature at which the heat exchange medium W filled in the outer pipe 4 can be vaporized. Since heat transfer is performed by vaporizing the heat exchange medium W, the heat transfer range can be expanded. (A-1) Hot Water Supply When hot water as a heat source is supplied to the heat supply pipe from the outside, the hot water flows from the inlet 9a of the heat supply pipe to the outlet 9b of the heat exchange panel P, and then to another heat exchange panel P. Inflow section 9a

温水温度より約２０℃低くなる。(A-2) Heat Exchange Processing When the hot water is supplied to the heat supply pipe, the heat exchange medium W in contact with the heat supply pipe is vaporized and filled in the outer pipe 4. Outer tube 4
When the heat exchange medium W comes into contact with the heat exchange medium W, heat is transmitted from the heat exchange medium W, and the temperature of the outer tube 4 itself increases. The heat exchange medium W to which the heat has been applied is liquefied, adheres to the inner wall of the outer pipe 4 and aggregates, moves down the inner wall, moves to the bottom, and contacts the heat supply pipe. While the hot water is being supplied, the heat exchange medium W
Is repeated, and heat continues to be transmitted to the outer tube 4. (A-3) Heat Dissipation Heat is transmitted to the outer plate 1 in contact with the outer tube 4 as the temperature of the outer tube 4 rises, and heat is radiated based on the specific heat of the outer plate 1. The contact portion a of the outer plate 1 becomes a surface along the outer periphery of the outer tube 4 to improve the transmission rate. In addition, the concave portion 5 provided in the general portion b forms an air layer having a large specific heat when the cover plate H comes into contact with the surface of the general portion b, so that the heat retention can be improved. Further, since the heat transfer plate 7 is provided on the front side top portion 6 of the contact portion a, the surface area of the outer plate 1 is enlarged, the heat transfer range is widened, and the amount of heat radiation is increased. Specifically, 60 in the heat supply pipe
When hot water of ° C. is flowed, the heat exchange medium W evaporates instantaneously and fills the outer tube 4. Due to this phenomenon, the entire heat exchanger 2 is heated to a temperature slightly lower than the flow of warm water.
According to the results of experiments so far, the surface of the outer panel 1 is lower by about 20 ° C. than the supplied hot water temperature.
