    • An inexpensive warm-up apparatus for an internal combustion engine having a simple structure and eliminating the need of forming a hole in a heat storage material retainer or the need for a seal around the hole or an electrical circuit. A heat storage material retainer (14) accommodating a latent heat type heat storage material (X) is arranged in a water jacket (13). The heat storage material retainer (14) has a nucleation device (2) that accelerates phase transition of the heat storage material in a supercooled state. The nucleation device includes a nucleation portion (24) for nucleating the heat storage material (X) in the supercooled state for phase transition, a hammer (25) supported in a movable manner, a target member (23) for applying impact to the nucleation portion by abutting against the nucleation portion when the hammer moves forward, and a lock mechanism (26) for restraining the hammer in the standby position by making use of the volume increase that occurs as the heat storage material undergoes phase transition to the liquid phase when receiving heat. The lock mechanism is released by vibrations generated when the internal combustion engine is started. The lock mechanism causes the hammer to abut against the target member to activate the nucleation device and nucleate the heat storage material.
    • 一种廉价的用于内燃机的预热装置,其具有简单的结构,并且不需要在储热材料保持器中形成孔或者需要围绕孔或电路的密封。 在水套(13)中设置有容纳潜热型蓄热材料(X)的蓄热材料保持架(14)。 蓄热材料保持器(14)具有使过热状态的储热材料的相变加速的成核装置(2)。 成核装置包括用于将过热状态的储热材料(X)成核以进行相变的成核部分(24),以可移动方式支撑的锤(25),用于对成核施加冲击的目标构件 当锤子向前移动时通过抵靠成核部分的部分;以及锁定机构(26),用于通过利用当储热材料经历相变到液相时发生的体积增加来将锤子抑制在待命位置 接受热量。 当内燃机启动时产生的振动释放锁定机构。 锁定机构使锤子抵靠目标构件以激活成核装置并使蓄热材料成核。
