Low heat dissipation energy-saving heater and its boundary ring structure

The present invention relates to a heater, and more particularly to a low heat dissipation energy saving heater and its boundary ring structure.

The flat panel heater is a common heating device for industrial and general household appliances. For example, the "plate heater" disclosed in the Chinese Patent No. 478289 has a flat plate shape, and after the heater is energized, the heat source is conducted from the intermediate portion to the middle portion. Border area. However, the boundary region of the conventional flat heater has no design to prevent heat dissipation, so that the heat source conducted from the intermediate portion to the boundary region may have a large heat dissipation loss due to heat conduction, heat convection and heat radiation, and further A significant temperature difference between the boundary area and the middle area is caused, which not only causes the flat heater to provide a uniform heating effect, but also makes the flat panel heater unable to meet the energy saving requirements. Therefore, it is necessary to provide an innovative and progressive low heat dissipation energy-saving heater and its boundary ring structure to solve the above problems.

The invention provides a low heat dissipation energy-saving heater comprising a boundary ring structure and a heater body. The boundary ring structure includes an annular vacuum portion, a first extension plate, a second extension plate, and a groove portion. The annular vacuum portion has an upper wall and a lower wall. The first extension plate is formed by extending one end of the upper wall of the annular vacuum portion. The second extension plate is formed by extending one end of the lower wall of the annular vacuum portion. The groove portion is formed between the first extension plate and the second extension plate. The heater system has an intermediate block and a boundary block. The intermediate block is located within the boundary block. The boundary block is embedded in the groove portion of the boundary ring structure.

The invention further provides a boundary ring structure, comprising an annular vacuum portion, a first extension plate, a second extension plate and a groove portion. The annular vacuum portion has an upper wall and a lower wall. The first extension plate is formed by extending one end of the upper wall of the annular vacuum portion. The second extension plate is formed by extending one end of the lower wall of the annular vacuum portion. The groove portion is formed between the first extension plate and the second extension plate for accommodating a heater body.

The boundary ring structure of the present invention can reduce the heat dissipation loss caused by heat conduction, heat convection and heat radiation of the boundary block of the heater body.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view showing the structure of a low heat dissipation energy-saving heater of the present invention. Fig. 2 shows a cutaway sectional view taken along line A-A of Fig. 1. Referring to FIG. 1 and FIG. 2, the low heat dissipation energy-saving heater of the present invention comprises a boundary ring structure 10 and a heater body 20.

Fig. 3 shows a cross-sectional view taken along line A-A of Fig. 1. Figure 4 is a cross-sectional view showing the boundary ring structure of the present invention. Referring to FIGS. 3 and 4 , the boundary ring structure 10 includes an annular vacuum portion 11 , a first extension plate 12 , a second extension plate 13 , and a groove portion 14 .

The annular vacuum portion 11 has an upper wall 111, a lower wall 112, a first side wall 113 and a second side wall 114. The upper wall 111 and the lower wall 112 respectively have a first inner wall surface 111a and a second inner wall surface 112a. The second side wall 114 is opposite to the first side wall 113, and the first side wall 113 and the first side wall 113 The second side wall 114 has a first inner side surface 113a and a second inner side surface 114a. In the embodiment, the first inner wall surface 111a, the second inner wall surface 112a, the first inner side surface 113a and the second side The inner side surfaces 114a are all mirrored. In addition, the upper wall 111, the lower wall 112, the first side wall 113, and the second side wall 114 of the annular vacuum portion 11 may form a geometric shape, which may be selected from a rectangular shape, a circular shape, and an elliptical shape. One of the groups formed, in the present embodiment, the geometry is rectangular.

The first extension plate 12 is formed by extending from one end of the upper wall 111 of the annular vacuum portion 11, and the second extension plate 13 is formed by extending one end of the lower wall 112 of the annular vacuum portion 11, and the groove portion is formed. 14 is formed between the first extension plate 12 and the second extension plate 13 . In this embodiment, the two ends of the second side wall 114 of the annular vacuum portion 11 are respectively connected to the first extension plate 12 and The second extension plate 13. In addition, in the embodiment, the heater body 20 is a high-conductivity heat-resistant material (for example, an aluminum alloy), and the material of the boundary ring structure 10 is a low-conductivity heat-resistant material (for example, stainless steel), and the boundary ring structure is The heat transfer coefficient of 10 is less than the heat transfer coefficient of the heater body 20.

Referring to FIG. 2 and FIG. 3 , the heater body 20 has an intermediate block 21 and a boundary block 22 . The intermediate block 21 is located within the boundary block 22, and the boundary block 22 is embedded in the groove portion 14 of the boundary ring structure 10. In this embodiment, the boundary block 22 of the heater body 20 can abut the second sidewall 114 of the annular vacuum portion 11 to increase the effect of the boundary ring structure 10 being fixed to the heater body 20. Preferably, the shape of the boundary ring structure 10 matches the shape of the heater body 20, that is, when the heater body 20 has a rectangular plate shape, the boundary ring structure 10 has a rectangular ring shape, and when the heating When the main body 20 has a circular plate shape, the boundary ring structure 10 has a circular ring shape.

In the present embodiment, if the heater body 20 has a rectangular plate shape, the boundary ring structure 10 may have two U-shaped configurations. When the heater body 20 is assembled with the boundary ring structure 10, the heater body 20 is embedded in the two U-shaped structures, and then the two U-shaped structures are joined to form a boundary ring having a rectangular ring shape. Structure 10.

In another embodiment, if the heater body 20 is in the shape of a rectangular plate, the boundary ring structure 10 can also have a U-shaped configuration plus an in-line configuration. The heater body 20 is assembled similarly to the boundary ring structure 10 as described above, and needless to say.

The boundary ring structure 10 of the present invention helps to reduce the boundary block 22 of the heater body 20 due to heat conduction because a low-conductivity heat-resistant material is used and its heat transfer coefficient is smaller than the heat transfer coefficient of the heater body 20. Heat dissipation loss. In addition, since there is no air flow inside the annular vacuum portion 11 of the boundary ring structure 10, it helps to reduce the heat dissipation loss caused by the heat convection of the boundary block 22 of the heater body 20. In addition, since the first inner wall surface 111a, the second inner wall surface 112a, the first inner side surface 113a, and the second inner side surface 114a are mirror surfaces, the mirror surface can effectively reflect heat radiation, thereby helping to reduce the heating. The boundary block 22 of the body 20 is thermally dissipated due to thermal radiation.

Since the heat dissipation loss of the boundary block 22 of the heater body 20 can be reduced by the present invention, the temperature difference between the boundary block 22 and the intermediate block 21 is reduced, and the heater body 20 is uniformly heated. effect.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the scope of the present invention. The scope of the invention should be as set forth in the appended claims.
