The invention relates to the technical field of vehicle-mounted refrigerators, and discloses an energy-saving temperature adjusting mechanism of a vehicle-mounted refrigerator, which comprises a machine body, a machine door movably mounted on the left side of the machine body, a semiconductor chilling plate fixedly mounted in the middle of an inner cavity of the machine body, and a fan fixedly mounted in the inner cavity of the machine body and located on the right side of the semiconductor chilling plate. An air cooling cavity located between the semiconductor chilling plate and the fan is formed in an inner cavity of the machine body. According to the energy-saving temperature adjusting mechanism, a vibration heat dissipation mechanism is arranged, so that when the vehicle-mounted refrigerator normally refrigerates and a vehicle vibrates in the running process, the piston block moves up and down in the air cooling cavity under the vibration effect, and therefore the ventilation groove continuously sucks air into and exhausts air from the air cooling cavity; the heating end of the semiconductor chilling plate is continuously subjected to air-cooling heat exchange in the air-cooling cavity, so that the temperature rise rate of the whole refrigerator body is reduced, the refrigeration efficiency of the refrigeration end of the semiconductor chilling plate is improved, and the problem that the refrigeration efficiency of the vehicle-mounted refrigerator is low, so that more energy is consumed for reaching the required temperature is solved.
本发明涉及车载冰箱技术领域,且公开了一种车载冰箱的节能调温机构,包括机体,机体的左侧活动安装有机门,机体内腔的中部固定安装有半导体制冷片,机体的内腔固定安装有位于半导体制冷片右侧的风机,机体的内腔开设有位于半导体制冷片和风机之间的风冷腔。本发明通过设置振动散热机构,使得在车载冰箱正常进行制冷,而车辆在行驶过程中发生振动时,活塞块在振动作用下,在风冷腔内上下移动,从而使通风槽不断向风冷腔内吸气和排气,使得风冷腔内对半导体制冷片的发热端不断进行风冷换热,使机体整体的升温速率降低,从而提高半导体制冷片制冷端的制冷效率,避免了车载冰箱制冷效率较低,导致达到所需温度所消耗的能源较多的问题。
