In various scenarios such as daily life, outdoor activities, in-vehicle environments, and medical transportation, cooling means for maintaining food, beverages, or medicines at low temperatures are required. Currently, many of the portable cold storage products commonly used in the market are gel-type cold storage agents. This type of product usually fills a gel-like refrigerant containing water, organic components, thickeners, preservatives, etc. in a polyethylene (PE) outer shell and uses it as a cold storage medium after freezing. However, this type of product has insufficient cooling efficiency, is prone to condensation and liquid leakage. Also, odors easily adhere to it, and the joints on the outer shell surface are difficult to clean. Furthermore, since it contains chemical components such as organic components, preservatives, and thickeners inside, there are also issues in terms of safety.

[0007] The specific embodiments of this invention will be described in more detail below with reference to the attached drawings. The same parts will be indicated by the same reference numerals in the drawings. It should be explained that the terms "front," "back," "left," "right," "up," and "down" used in the following description are based on the directions shown in the attached drawings. Furthermore, the terms "inside" and "outside" refer to the direction toward and away from the geometric center of a specific component, respectively. Unless otherwise specified, technical and scientific terms used herein have their common meanings in the art. The use of terms herein is limited to describing specific embodiments and does not limit the invention. The expression "and / or" means one or any combination of the enumerated items. In order to provide a clearer understanding of the present invention, the technical means included in the embodiments will be described clearly and completely below, with reference to the drawings relating to the embodiments of the present invention.
[0008] As shown in Figures 1 to 3, the portable antibacterial cooling plate comprises a metal outer shell 1 and a cooling material 2 filled inside the metal outer shell 1. The metal outer shell 1 is integrally sealed by molding, and a sealed space 3 is formed inside. The metal outer shell 1 is made of an antibacterial metal material, preferably one of antibacterial stainless steel, titanium, or titanium alloy. In this embodiment, antibacterial stainless steel is used as the metal outer shell 1. This provides excellent thermal conductivity and effectively suppresses bacterial growth, thus meeting the safety requirements for food contact applications. The metal outer shell 1 includes a first plate 4 and a second plate 5 that are spaced apart and facing each other. The first plate 4 and the second plate 5 are sealed by welding, and the welded area is polished after welding. By welding the first plate 4 and the second plate 5 together and then polishing the welded area after welding is complete, the outer surface of the metal shell 1 can be made smooth and flat. Furthermore, the corners of the metal shell 1 are rounded to prevent damage to the user's fingers or the contents during carrying. The cold storage material 2 is filled into the sealed space 3. The cold storage material 2 can be at least one of a liquid, a semi-solid, a gel, and a phase change material. In this embodiment, a phase-change thermal storage material (PCM) is used as the thermal storage material 2, and its phase-change temperature can be adjusted according to the usage requirements. The thermal storage material 2 stores cold by cooling and releases the stored cold when in use. In this context, "cold storage by cooling" refers to placing a cooling plate in the freezer compartment to cool the cold storage material 2 and storing that cold energy.
[0009] In actual use, the outer shape of the metal shell 1 is flattened, and its plan view shape can be any one of the following: rectangle, square, circle, ellipse, polygon, or rounded quadrilateral. Furthermore, the outer shape of the metal shell 1 can be designed as either elongated, curved, or wavy, thereby allowing it to adapt to different usage scenarios and the shape requirements of the object being cooled. This invention combines the high thermal conductivity of a metal outer shell with the phase-change cooling effect of a thermal storage material. The metal outer shell is integrally sealed and molded from an antibacterial metal material, and the thermal storage material is filled inside. Before use, the cooling plate is placed in a low-temperature environment to pre-cool the thermal storage material and store cold energy. When in use, the thermal conductivity of the metal material is significantly higher than that of conventional resin materials, allowing for rapid transfer of cold and heat when the cooling plate comes into contact with the object being cooled, resulting in highly efficient cooling. The cold storage material utilizes temperature changes and phase change latent heat to exert a continuous cooling effect, maintaining the object being cooled at a low temperature. Overall, the flat, sealed structure reliably prevents leakage of the cold storage material, and the antibacterial properties of the metal shell suppress bacterial growth, ensuring safety in food contact applications. Furthermore, any parts not described in detail in this specification are considered to be publicly known technology that is well known to those skilled in the art.

The drawings also show only one embodiment of the present invention, and actual applications are not limited thereto. In other words, any structural configurations and embodiments similar to those of the technical means, designed by a person skilled in the art based on their suggestions and without departing from the spirit of the present invention, should all fall within the scope of protection of the present invention.
