Accompanying drawing explanation
Fig. 1 is the structural representation of the cold-storage device that provides of the utility model specific embodiment;
Fig. 2 is the structural representation of the refrigerator drawer door with cold-storage device that provides of the utility model specific embodiment;
Wherein:
1: box body; 2: lid; 3: sealing ring; 4: buckle is installed; 5: drawer door; 6: cold-storage device; 7: door courage.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate the technical solution of the utility model.
The application provides a kind of cold-storage device, especially a kind of cold-storage device that contains energy storage material, the both sides up and down that it is applicable to the drawer door that is arranged on drawer door refrigerator, can effectively reduce refrigerating chamber cold consumption, play better energy-saving effect and anti-cold draining effect.
As shown in Figure 1, above-mentioned cold-storage device comprises box body 1 and lid 2, wherein, box body 1 and the mutual snapping of lid 2, the seal connecting in order to improve both, is provided with sealing ring 3 between box body 1 and lid 2.In above-mentioned box body 1, be provided with energy storage device (not shown); the heat release under refrigerator work of this energy storage device; when freezer compressor shutdown or thermic load increase, pass through decalescence released cold quantity; temperature in can balance refrigerator; prevent that refrigerator cold draining from causing the problem of refrigeration for refrigerator Efficiency Decreasing; the effectively temperature rise in containment refrigerating chamber, refrigeration and the anti-cold draining effect of raising refrigerator.
In this embodiment, preferred, in energy storage device, be filled with energy storage material, this energy storage material is phase change medium, and the phase transition temperature of this phase change medium is-16 ℃ to-20 ℃, enthalpy of phase change is 180J/g to 220J/g.Further preferred, phase change medium is the mixed solution of 25% ethylene glycol solution and 25% ammonium nitrides solution, 30% ammonium nitrides solution or 35% ammonium nitrides solution.
The concrete connected mode of box body 1 and lid 2 is: on box body 1, be provided with seal groove (not shown), sealing ring 3 is with lid 2 by being welded to connect, and lid 2 and box body 1 be when coordinate, and sealing ring 3 inserts in seal groove, can play thus better sealing effectiveness.
