Description

Technical Field

[0001] The utility model relates to the technical field of cold storage equipment, and particularly relates to a high-strength and high-efficiency phase change cold storage ice box. Background Technique

[0002] The phase change cold storage ice plate is an innovative thermal management technology, and its core lies in the efficient storage and release of energy by utilizing the special properties of phase change materials. With the continuous growth of global energy demand and the increasingly severe environmental problems, the research and application of high-efficiency energy storage technologies have become the key. The phase change cold storage ice plate exactly conforms to this trend. Through the large amount of latent heat absorbed or released when the phase change material converts between the solid state and the liquid state (or gaseous state), it realizes the stable storage and demand-based release of energy. This technology mainly consists of a phase change material layer and a heat conduction plate layer. The phase change material layer is the core, responsible for absorbing or releasing heat during the phase change process; the heat conduction plate layer is responsible for evenly conducting heat to the phase change material, improving the energy conversion efficiency. The phase change cold storage ice plate not only has advantages such as high energy density, long periodicity, and stable temperature control, but also has characteristics such as environmental protection, energy saving, safety, and reliability, and can be widely applied to multiple fields such as cold chain logistics, building temperature regulation, and electronic equipment heat dissipation.

[0003] In cold chain logistics, the phase change cold storage ice plate can effectively maintain the low temperature state of goods and reduce losses; in the building field, it can help regulate indoor temperature and reduce air conditioning energy consumption; in electronic equipment, it can significantly improve the heat dissipation efficiency and ensure the stable operation of the equipment. With the continuous maturity of technology and the continuous expansion of application fields, the phase change cold storage ice plate will play a more important role in future energy management and energy conservation and emission reduction. For example, the ice plates (ice boxes) recorded in References 1 and 2:

[0004] Reference 1: Chinese patent document with the application number CN2017213399659

[0005] Reference 1 records an ice plate. The ice plate is an article for storing energy. Generally, the ice plate is a material used for phase change cold storage. Generally speaking, the phase change cold storage material is stored in the ice plate body, and the cold quantity latent heat is stored by means of chilled water. The ice plate has a body, and a storage cavity is formed in the body. A flow channel is arranged on the body, and the flow channel is formed radially from the center point of the body to both sides. A flow channel is additionally arranged on this ice plate, so that the energy is released faster, and the flow channel is symmetrically arranged radially from the vortex groove at the center point to both sides, so that the energy is released more evenly, solving the disadvantages of the existing ice plate that the cold release and cold storage are slow and uneven.

[0006] Reference 2: Chinese patent document with the application number CN2018209573144

[0007] Reference 2 describes a phase change cold storage ice plate with high sealing performance and high stability, which includes a cold storage plate body, a cold storage bottle mouth, a convex platform large hole groove, a small hole groove, a concave platform large hole groove, a reinforcing block, a sealing inner plug and a cold storage bottle cap. Two rows of convex platform large hole grooves are symmetrically arranged on the top surface of the cold storage plate body. Two rows of concave platform large hole grooves are symmetrically arranged on the bottom surface of the cold storage plate body. The positions of the concave platform large hole grooves correspond to those of the convex platform large hole grooves, and the structural shapes of the concave platform large hole grooves and the convex platform large hole grooves are matched. Reinforcing blocks are fixed at the joints of the ends of the concave platform large hole grooves and the convex platform large hole grooves and at the joints of the ends of the small hole grooves. This phase change cold storage ice plate concentrates the pressure on the reinforcing blocks through the small hole grooves, the convex platform large hole grooves and the concave platform large hole grooves, greatly reducing the stress on the main body of the phase change cold storage ice plate and enhancing the compressive resistance. At the same time, the designed height of the sealing inner plug is flush with the top end of the cold storage bottle mouth, preventing the sealing inner plug from retracting and increasing the sealing performance of the device.
