And the temperature of the high-temperature liquid heated by the heating component 2 is higher than the temperature of the cooling liquid in the first heat exchange channel 40 when the high-temperature liquid flows through the second heat exchange channel 42, so that the first heat exchange channel 40 can continuously absorb the heat of the liquid such as water in the second heat exchange channel 42, and the heat exchange between the first heat exchange channel 40 and the second heat exchange channel 42 is realized, and the cooling of the liquid such as water in the second heat exchange channel 42 can be realized through the heat exchange between the first heat exchange channel 40 and the second heat exchange channel 42. The structure can cool the liquid such as water heated by the heating device by utilizing the heat exchange principle, and the cooling mode has simple structure and easy realization, thereby simplifying the structure of the product and reducing the cost of the product.
