Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to heaters used for space heating, warming, anti-freezing, etc., and particularly relates to infrared radiant heaters for warming with high radiation efficiency. The present invention relates to a heater having a structure that emits radiation uniformly over the entire range, while also eliminating directivity.

Structure of the conventional example and its problems As shown in FIG. There is one filled with non-flammable oil 3 inside. Another conventional example is one in which a planar heater 4 is arranged on the inner surface of a box 1, as shown in FIG. Furthermore, instead of the planar heater 4, there is also one in which string-like heaters are arranged in a distributed manner. In these conventional infrared radiant heaters, the surface temperature of the box 1 is raised to 70 to 70°C by energizing the electric heater 2 and passing the nonflammable oil 3 or by energizing the sheet heater 4.
The temperature is maintained at 90° C., and infrared rays are radiated using the heated surface of the case 1 as a heat source. In this case, since the box 1 is a flat surface, the view factor decreases as the angle from the normal to the 1,000 faces of the box increases, and becomes 0 at an angle of 90°, that is, the view factor of the box 1 Although it is warm in the front direction, it is not warm in the vicinity of the sides.Objective of the InventionThe present invention solves such conventional problems, and it is possible to narrow or widen the radiation width. The purpose of this invention is to provide a heater for temperature collection that is variable so as to allow heating.

Structure of the Invention In order to achieve this object, a heat source body erected in a nearly vertical direction, an infrared radiating material layer formed on one surface of the heat source body, and a layer near the surface of the infrared radiating material layer are provided. It consists of a plurality of thin plate-like protrusions installed perpendicular to the heat source body and in the vertical direction, and a heat insulating layer installed on the other surface of the heat source body, and the heat source body is It is constructed so that it can be bent freely.

With this configuration, when the heat source is in a nearly flat state, the distribution of radiant energy radiated to the front surface due to the thin plate-like protrusions becomes extremely narrow, and the directivity increases compared to a completely diffused surface. It becomes a trend. Therefore, when the heat source is bent in a convex shape in the horizontal direction, the normal direction at each position of the heat source is different, making it impossible to distribute the radiant energy uniformly in all directions. can.

As described above, the present invention provides a heater that can emit radiation in a desired direction, both narrowly and widely.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be explained with reference to FIGS. 3, 4, 5, and 6.
This will be explained using figures.

In FIGS. 3, 4, 5, and 6, a heat source A having a planar heater 6 disposed on one surface of a substrate 5 is erected almost vertically. On the other surface of the substrate 5, an infrared radiating material layer 7 of 10 to 200 μm is coated or adhered. This infrared radiating material layer 7
Perpendicular to the heat source A near the surface of and the height in the vertical direction:
Thin plate-shaped protrusions 8 having 5 to 30 LHs and a thickness of 0.06 to 1.0 mm are installed at intervals of LP: 2.5 to 60rrrrh.

Approximately 16 pieces of heat insulating material 9 such as glass wool are installed on the surface of the planar heater 6 of the heat source A, so that it can be bent relatively freely. Note that the arrows in FIGS. 4 and 5 indicate the normal direction.

In the above configuration, when the heat source A is made almost flat, when there is no thin plate-like protrusion 8 (solid line) and when there is (broken line)
Figure 6 shows the radiant energy distribution. In the same figure,
If there is a thin plate-like protrusion, the distribution of radiant energy will be very narrow, and the density will increase in the normal direction of the heat source, and as the angle from the normal direction increases, the radiant energy density will become extremely narrow. Decrease. In other words, the directionality is improved. Here, since this heat source A can be bent into a convex shape, it radiates directionally in the normal direction of the heat source A at each position, so radiation is emitted uniformly in all directions. becomes possible.

Effects of the Invention As described above, the heater of the present invention provides the following effects.

O) If the heat source body is made substantially flat, it becomes a radiation heater with high directivity.

(2) By bending the heat source into a convex shape, it becomes a radiant heater that emits uniform radiation. (3) Even when it is installed in direct contact with the wall of a house, the directivity is large, so There is little radiation to the wall.
