AI Technical Summary

⚠Technical Problem

Traditional evaporator structures for making round ice blocks suffer from problems such as low heat transfer efficiency, uneven temperature distribution, high contact thermal resistance, and difficulty in demolding the ice blocks after they are formed, making it difficult to produce spherical or semi-spherical ice blocks.

⚗Method used

The device employs a split structure consisting of mold number one and mold number two. The coolant channels are evenly distributed along the outer surface of the mold. The opening and closing mechanism enables precise molding and rapid demolding of ice blocks. The coolant channels are integrated with the mold to improve heat transfer efficiency.

🎯Benefits of technology

It improves ice-making efficiency and the aesthetics of ice blocks, enabling efficient preparation and convenient demolding of spherical ice blocks.

Abstract

This utility model relates to the field of ice-making device technology and discloses a high-efficiency spherical evaporator mold, including a first mold and a second mold. The first mold is hemispherical with a hollowed-out hemispherical ice-making space inside. The outer surface of the first mold is integrally machined with coolant channels distributed in a ring along the curved surface, allowing coolant to flow inside the coolant channels. The two ends of the coolant channels are connected to the evaporator. The side surface of the ice-making rack is provided with an opening and closing mechanism. The second mold is installed inside the opening and closing mechanism. The second mold is the same size as the first mold and has a hollowed-out ice-making space of the same specifications as the first mold. This utility model has the advantages of high-efficiency ice making and simple structure, and solves the problem of uneven heating and low ice-making efficiency in the production of round ice in the prior art.
