This invention discloses a heated tobacco cooling unit with enhanced thermal conductivity and a heated tobacco product, comprising a carrier sheet, several metal foils, and several phase change cooling materials. The carrier sheet has several perforated holes. Several metal foils are disposed on at least one side of the carrier sheet and cover the perforated holes. The metal foils are spaced apart and discretely arranged. The phase change cooling materials are filled within the perforated holes using the metal foils as a carrier. The carrier sheet containing the metal foils and phase change cooling materials is formed into the heated tobacco cooling unit by at least one of the following methods: winding, folding, gathering, bending, and pleating. The metal foils are regularly and intermittently distributed along the longitudinal direction of the tobacco strip. The cooling unit has multiple longitudinally extending channels, and the porosity of the cross-section is 40%-90%. The heated tobacco cooling unit with enhanced thermal conductivity of this invention has the advantages of high latent heat of phase change, low thermal hysteresis effect, high heat absorption efficiency, apparent stability without collapse, and no leakage.

The utility model discloses a dual-purpose heat insulation shower faucet which comprises a shell, a cold water inlet, a hot water inlet, a temperature adjusting valve, a waterway switching valve, a first waterway outlet and a second waterway outlet, the temperature adjusting valve and the waterway switching valve are arranged at the two ends of the shell, and the cold water inlet, the hot water inlet, the first waterway outlet and the second waterway outlet are arranged on the shell. A heat insulation water way assembly is arranged in the shell, a heat insulation gap is formed between the heat insulation water way assembly and the shell, the heat insulation water way assembly comprises a first heat insulation water way piece and a second heat insulation water way piece, and a sealing piece is arranged between the first heat insulation water way piece and the second heat insulation water way piece. Cold water and hot water are mixed in the temperature adjusting valve through a water path in the heat insulation water path assembly, mixed water formed after mixing enters the water path switching valve through a mixed water path in the heat insulation water path assembly, and the water heater has the advantages that the internal structure is simplified, and the heat insulation performance is good.
