In addition, the heating powders 21 are preferably made of a polycarbonate material so that light can be transmitted therethrough.

The warm air device (P) using solar light according to the present invention is provided with a heating means 30 for collecting the sunlight to heat the powder set 20, more specifically, the heating means 30 is the powder It is provided in part or all of the set 20, and consists of a condensing lens 31 for collecting sunlight, and a conducting member 33 which is heated by the sunlight collected through the condensing lens 31.

More specifically, as shown in FIG. 4, the conductive member 33 of the heating means 30 is provided in each of the plurality of heating powders 21 constituting the second powder set 24. The condenser lens 31 is provided in plural so as to correspond to the heating powders 21 on the support member 41 of the height adjusting member 43 provided on the second powder set 24 which will be described later. .

In addition, the conductive member 33 is made of a copper plate is high thermal conductivity to easily heat the air inside the heating powder 21, it is also preferable to use other materials with high thermal conductivity, in order to reduce the manufacturing price It is more preferable to comprise with a copper plate.

Therefore, the air passing through each heating powder 21 constituting the second powder set 24 is the air passing through the conductive member 33 by heating the conductive member 33 provided in each heating powder 21. The heat is received by the conductive member 33 is heated to be discharged to the outside of the housing 10.

Again the warm air device (P) using the sunlight according to the present invention is further provided with a temperature control means 40 for controlling the temperature inside the heating powder 21,

As shown in FIG. 4, the temperature adjusting means 40 is provided above the second powder set 24, and supports a plurality of condensing lenses 31, which are components of the heating means 30, are coupled to a plurality of means.

The support member 41 is coupled to the thread provided on the outer surface of the support member 41 and the support member 41 according to the rotational direction of the temperature control cap 431 as the support member 41 moves along the thread. The separation distance of the two powder sets 24 is changed.

Therefore, the condenser lens 31 provided on the support member 41 collects sunlight to heat the conductive member 33, and the separation distance between the second powder set 24 and the support member 41 is increased. By changing the area of the focus of the sunlight collected by the condensing lens 31 is changed, by changing the temperature of the sunlight transmitted to the conductive member 33 is conducted to the air passing through the second powder set 24 Allow the temperature to change.

In the case of the temperature control, when the focus is changed through the condenser lens 31, the narrower the area, the more the sunlight is concentrated in one place, so that the partial temperature of the focus is higher than when the area of the focus is relatively wide. You can adjust the temperature as you change.

Furthermore, FIG. 5 illustrates a modification of the conductive member. The upper surface of the conductive member 33, that is, the heat transfer surface 332 that receives heat through the condensing lens 31 may be a flat surface. As shown in the dashed line, the curved portion 332A or the curved portion 332B is preferably formed at the center lower portion of the heat transfer surface 332, thereby preventing the heat from being reflected by the reflection of sunlight.

Again, the conductive member 33 conducts heat by directly contacting the air, and in order to improve the thermal conductivity, it is preferable to improve the contact area with the air and not to disturb the air flow.

5 to 7, the conductive member 33 is formed in a cylindrical shape and has a top and bottom opening portion 161.

In more detail, the conductive member 33 forms a hollow 331A, and inner walls 331 contacting the heat transfer surface 332 and radially protrude outward from both end portions of the inner wall 331. Since the heat dissipation pieces 333 and the outer end portions of the heat dissipation pieces 333 are interconnected, the outer walls 336 are formed at positions intersecting the inner walls 331.

Internal heat dissipation passages 338 communicating with the hollow 331A between the heat dissipation pieces 333 and external heat dissipation passages 339 communicating with the outside of the conductive member 33 are formed.

Conductive member 33 composed of the inner wall 331, the heat dissipation piece 333 and the outer wall 336 is preferably molded in a productive extrusion method,

For reference, the conductive member 33 may be heated to expand the hollow 331A, and then the heat transfer surface 332 may be inserted, and the conductive member 33 may be heated, and the heat transfer surface 332 may be cooled. Afterwards, the heat transfer surface 332 may be inserted into the hollow 331A.

The inner wall 331 is in direct contact with the heat transfer surface 332 to transfer heat collected from the condensing lens 31 to the entire conducting member 33, and at the same time to contact the air inside the conducting member 33. The air passing through the powder set 24 is heated.

The present invention forms the first heat dissipation protrusion 335a to be bent in an outward direction so that a pair of first heat dissipation protrusions 335a face each other to form a circular coupling auxiliary hole 335A and 335B.

In addition, the second heat dissipation protrusion 335b is formed to protrude from the heat dissipation piece 333 facing each other to form the external heat dissipation passage 339, and is formed to be bent toward the inner side (inner wall 331). The second heat dissipation protrusion 335b may be utilized as the second coupling assistant.

The outer wall 336 may further include heat dissipation fins 337 protruding toward the outer heat dissipation passage 339.

The heat dissipation fins 337 are preferably formed over the entire outer wall 336 along the longitudinal direction of the external heat dissipation passage 339.

The present invention improves the air contact area of the external heat dissipation path 339 through the heat dissipation fins 337, and assists air circulation of the external heat dissipation paths 339 through the separation space formed between the heat dissipation fins 337. together,

With the air circulation through the separation space formed between the heat dissipation fins 337, the heat dissipation fins 337 are guided to discharge the hot air from the bottom, there is an advantage that can maximize the heat dissipation performance.

In order to improve heat dissipation through the conductive member 33 and the air circulation function in the conductive member 33,

The conductive member 33 includes an outward cutout 334 formed by partially cutting the outer walls 336 and the heat dissipation pieces 333, so that the inner heat dissipation passage 338 and the conductive member 33 are formed. An air communication hole 334A for communicating the outside is formed.

The outward cutout 334 may be simultaneously formed during extrusion of the conductive member 33, or may be formed through a separate etching process after the conductive member 33 is formed.

The outward cutout 334 forms an air communication hole 334A in a direction orthogonal to the internal heat dissipation passage 338,

In all cases installed at various installation angles, the internal air of the conductive member 33 is circulated through the heat dissipation passages 338 and 339 and the air communication hole 334A, thereby ensuring excellent heat dissipation performance. This is very big.
