High-temperature-resistant router

The invention discloses a high-temperature-resistant type router. The router comprises a router body, cylinders are fixedly embedded in the two side walls of the router body, sleeves connected with the cylinders in a sealing and rotating mode are evenly distributed on the cylinders, liquid storage cavities filled with evaporation liquid are formed in the wall bodies of the sleeves at equal intervals, and iron sheets are fixedly connected to the inner walls of the liquid storage cavities. A pushing mechanism, a heat absorption mechanism, a shell, a sliding plug, a hot air inlet and a hot air outlet are arranged; when the router works to generate a large amount of heat, the evaporated liquid absorbs heat and evaporates into gas to be sprayed out; the sleeve is pushed to rotate, cooling of evaporated gas and recycling of evaporated liquid are achieved in the rotating process of the sleeve, and therefore circulation of the actions is achieved, the cooling effect on the router is achieved,hot air in the router can
