Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a radiator that uses hot water, steam, etc. as a heat source and radiates heat using a radiator plate.

[Prior Art] As a conventional heat radiator of this type, one consisting of a single heat radiating unit called a heat panel is known.

[Problems to be solved] However, these conventional radiators simply contact and heat the air on both sides of the radiator unit.
Heating efficiency was not very high.

[Means for solving problems] The present invention has been made in view of the above points, and is a radiator that uses hot water, steam, etc. as a heat source, and includes: (a) a frame having ventilation holes with spaces between them; (b) Each of the pair of heat radiating units includes a temperature at or near the heating temperature on at least one of the two metal plates. A groove is provided as a flow path for the working fluid that forms an evaporation/condensation cycle in a temperature range, and the two metal plates are tightly joined with the grooved surface facing inside to seal the groove. It is characterized by comprising a heat sink whose groove is filled with an appropriate amount of the working fluid, and a heating means that comes into contact with a portion of the groove of the heat sink to heat the working fluid.

[Example] The present invention will be described below based on an example shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of the radiator of the present invention, and FIG. 2 is a partially enlarged view thereof.

The radiator shown in the figure has a pair of heat radiating units 1, 1 installed in an opening of a frame 31 facing each other, and a common water inlet 23 and A flat hot water pipe 21 with a protruding drain port 24 is installed as a heating source.

The heat dissipation units 1, 1 are spaced apart by a predetermined distance, and a spacer 33 is provided for reinforcement. or,
Ventilation holes 32 are provided on the upper and lower sides of the frame 31. Therefore, a heating area A is formed between the two heat radiation units 1, 1. The heat dissipation unit 1 includes two metal plates 11A with good thermal conductivity, such as aluminum and copper.
11B, grooves 12 are formed on one side of each by pressing or the like.
are arranged symmetrically in a certain pattern, the patterns of the grooves 12 are made to correspond to each other with the surface provided with the grooves 12 inside, and these metal plates 11A and 11B are tightly joined by crimping, welding, or other means. be done. An appropriate amount of hydraulic fluid 15 is filled in the groove 12 .

In this heat dissipation unit, the lowermost longitudinal groove 12 serves as a heating section 13. Also, another groove part 1
Reference numeral 2 serves as a heat dissipation section 14, which serves as a flow path for the working fluid 15 and its vapor 16. The grooves 12 are in the form of a grid and all communicate to form an integral container, allowing the steam 16 to move freely within the heat dissipation unit 1. Therefore, the surface temperature distribution of the metal plates 11A and 11B is made uniform. However, the pattern of the groove portions 12 is not limited to a lattice shape, but may be a lattice shape or other shapes.

Note that a plurality of sealed container blocks may be formed in one heat dissipation unit 1 by appropriately partitioning the communication in the lateral direction of the groove portion 12.

The working fluid 15 may be one that can form an evaporation/condensation cycle in a temperature range of heating temperature or its vicinity, such as freon, water, acetone, or methanol. For example, Freon R11
By selecting a material that evaporates easily at a temperature of 20°C to 40°C, the heating source temperature can be lowered. However, one that evaporates at an even lower temperature may be used.

Note that the filling into the groove portion 12 is performed using an appropriate groove portion 12.
An injection pipe (not shown) is installed in advance at a suitable location, and after the air in the groove 12 is exhausted through this, the working fluid 15 is appropriately injected taking into account the vapor pressure, and finally the injection pipe is sealed. The injection amount may be, for example, approximately 10% of the internal volume of the groove portion 12. In this state, the working fluid 15 and its vapor 16 mainly exist inside the heat sink 1 . However, a non-condensable gas such as air may be mixed in the heat sink 1.

The hot water pipe 21 is recessed so as to fit into the outer wall of the groove of the heating section 13, and is attached by screws or other means. Note that it is effective to cover the contact portion and its surrounding area with a material having good thermal conductivity such as fluid paraffin.

The temperature of the hot water varies depending on the operating temperature range of the working fluid 15, but may be from 20°C to 70°C, with 40°C being an appropriate temperature.

In the above embodiment, two metal plates 11A, 11B
Although the groove portions 12 were provided symmetrically on both sides, the groove portions 12
can also be provided asymmetrically. For example, the grooves may correspond to the flat plate portions of the other, or, as shown in FIG. may be made into a flat plate.

Further, in the above embodiment, the hot water pipe 21 is connected to the groove 1.
2, the hot water pipe 21 may be inserted into the groove 12 as shown in FIGS. 4 and 5.

Next, the heating effect in this embodiment will be explained.

The radiator of this embodiment has a water inlet 23 and a drain outlet 2.
A hot water supply pipe and a drain pipe (both not shown) are connected to each of the hot water pipes 21 and 4, and heat is radiated by flowing hot water through the hot water pipe 21.

When hot water flows through the hot water pipe 21, the heat of the hot water is transferred from the inner wall of the groove 12 in the heating section 13 of each heat radiating unit 1 to the working fluid 15 stored inside, thereby heating the working fluid 15. When the heated working fluid 15 evaporates, a pressure difference is created between the heating part 13 and the heat radiation part 14, and the vapor 16 of the working fluid 15 moves at high speed through the groove part 12 as a flow path, touches the inner wall of the heat radiation part 14, and Metal plates 11A, 11 of heat exchanger and heat dissipation unit 1
Heat B. After this heat exchange, the working fluid 15 is cooled, condensed, and returned to a liquid state. The working fluid 15 flows down or drips along the inner wall of the groove, and returns to the heating section 13.

The air in the heating area A is heated by the outer walls of the heat dissipation unit 1 on both sides, rises as if in a chimney as shown by the arrow in Fig. 2, and is discharged from the upper ventilation hole 32 to be used for heating. Served. In addition, as the air in the heating area A rises, the lower ventilation hole 3
Fresh air is drawn in and introduced from 2 and heated in the same way. Of course, the surrounding air is also heated by the outer wall surfaces on the outside of both heat radiating units, and is provided for heating.

In addition to hot water, for example, steam, hot air, etc. may be used as a heating means, and electric heaters,
The heating means may be composed of a heat pump. Moreover, it is not limited to the floor-mounted type, but may also be a wall-mounted type or a wall-embedded type. Furthermore, a wick made of felt, fiber, or the like may be installed in the groove 12 so that the flow is refluxed using capillary action.

[Effect of the invention] Since the radiator of the present invention is as described above, not only the outer surface of the radiator contacts and heats the air, but also the heating area between the pair of radiator units functions like a chimney. As it emits light, new air is sucked in, heated and released, making efficient heating possible.
