Detailed ways

As shown in Fig. 1, it is a kind of far-infrared heater described in the utility model, and it comprises a shell 1, and described shell 1 is made of metal material, and described shell 1 is provided with a plurality of heat dissipation openings 4, at least A part of the heat dissipation openings 4 are arranged on the lower part of the housing 1. Preferably, the heat dissipation openings 4 are oval and evenly arranged on the lower part of the side wall of the housing 1. The heat dissipation openings 4 can also be arranged as required Different shapes and quantities. As shown in FIG. 1 , a part of the heat dissipation openings 4 are provided on the lower part of the side wall of the housing 1 , and a part of the heat dissipation openings 4 are arranged on the upper part of the side wall of the housing 1 .
