The heat conducting structure can be made of heat conducting silicone grease or tin paste and the like. The reflective metal structure 24 may reflect light that is reflected back through the metal substrate 14 at the bottom. The end cap 26 is disposed on the second surface 142 of the metal substrate 14 and is connected to the housing 12 to protect the internal components.

Specifically, the upper end of the metal sleeve 18 is conical to form a function similar to a reflective cup, so as to reflect the light emitted by the deep ultraviolet light source 16 back and forth in the chamber to kill the water, and at the same time, the heat generated by the deep ultraviolet light source 16 can be taken away by the water.
In one embodiment, the metal substrate 14 is an aluminum substrate, which has high structural strength and excellent electrical conductivity, thermal conductivity, and corrosion resistance.
In one embodiment, as shown in FIG. 4, the metal substrate 14 is circular in shape. However, the present invention is not limited thereto, and the metal substrate 14 may have other shapes such as a square shape, an oval shape, and a polygonal shape. The number of the deep ultraviolet light sources 16 is four, and the deep ultraviolet light sources are arranged on the first surface 141 of the metal substrate 14 in a rectangular array manner, so that a better killing effect is provided.
In summary, an advantage of the present invention is to provide a deep ultraviolet light source heat dissipation structure 10 for a running water sterilization module, in which a metal sleeve 18 is used to communicate a water inlet pipe 20 and a water outlet pipe 22, so that a cooling cavity 182 filled with water liquid is formed inside the metal sleeve 18, and when heat generated by a deep ultraviolet light source 16 is transferred to the metal sleeve 18 through a metal substrate 14, the metal sleeve 18 can dissipate heat through the cooling cavity 182, that is, absorb heat by a water cooling method, so that the deep ultraviolet light source 16 maintains a lower temperature during operation.
