<p>A container (14), which contains a latent heat storage material (X), is provided in a water jacket (13) of an internal combustion engine. A nucleation device (2) is provided in the container. The nucleation device includes a plate-like member (29), which is formed of bimetal, a water wheel (25), which is located in the water jacket, a rotating body (23), which is located in the container, and claws (24), which extend radially from the rotating body. When coolant starts circulating in the water jacket as the engine is started, the water wheel is rotated, thereby rotating the claws of the rotating body. The claws scratch the surface of the plate-like member to form a new surface. The nucleation device operates to nucleate the heat storage material by bringing the new surface into direct contact with the supercooled heat storage material. Thus, an inexpensive warming-up device of the internal combustion engine having a simple structure is provided.</p> |
