Energy storage plate refrigeration passive vehicle-mounted refrigerator with rapid unfreezing function

Abstract

The invention relates to the technical field of vehicle-mounted refrigerators, in particular to an energy storage plate refrigeration passive vehicle-mounted refrigerator with a rapid unfreezing function. The energy storage plate refrigeration passive vehicle-mounted refrigerator comprises a box body, wherein a refrigeration box and an unfreezing box are arranged in the box body in a sleeved mode.Gaps are formed between the cold closet and the left side and the right side of the box body, the left end and the right end of the refrigeration box are provided with heat conduction surfaces, and the lower end of the refrigeration box is provided with a heat insulation surface. The unfreezing box is arranged at the lower end of the refrigeration box and is provided with heat conduction liquid.Rotating shafts are arranged at the upper ends of the left sides and the right sides of the gaps, the rotating shafts are fixedly connected to the box body and the heat conduction surfaces, handles ofthe rotating shafts are arranged on the outer side of the box body, the rotating shafts are fixedly connected with connecting wires, the other ends of the connecting wires are fixedly connected withphase-change constant-temperature material bags, and phase-change constant-temperature materials are arranged in the phase-change constant-temperature material bags. Heat insulation flexible surfacesare arranged at the left end and the right end of the heat insulation surface. The device is good in refrigeration effect, good in unfreezing effect, simple in structure, and environment-friendly andenergy-saving, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted refrigerators, in particular to an energy storage plate refrigeration passive vehicle-mounted refrigerator with rapid thawing. Background technique [0002] Phase change materials refer to substances that change shape with temperature and can provide latent heat. The process of a phase change material changing from solid to liquid or from liquid to solid is called a phase change process. At this time, the phase change material will absorb or release a large amount of latent heat. Phase change materials can actually act as energy storage. This feature is of great significance in the fields of energy saving and temperature control. [0003] The existing phase-change low-temperature energy storage materials mainly use Na 2 SO 4 10H 2 O is the main raw material, and its energy storage calorific value per unit mass is extremely large, about 241 J / g. The purpose of temperature control can ...
