TECHNICAL FIELD
[0001] The utility model relates to ice making technical field especially a full -liquid type pipe ice evaporator. BACKGROUND
[0002] The working principle of the tube ice machine is mainly based on physical cooling and phase change process, and the core is to convert water into ice through a circulating cooling system. The working principle of the tube ice machine can be divided into four basic steps: evaporation, compression, condensation and expansion (or called refrigerant cycle, heat exchange, ice formation and ice block shedding).
[0003] The tube ice machine evaporator is one of the core components of the tube ice machine, which plays a crucial role in the ice making process.
[0004] Refrigerant cycle:
[0005] Liquid refrigerant is supplied from a low-pressure liquid reservoir and enters the evaporator after being depressurized by a throttling valve or expansion valve.
[0006] In the evaporator, the refrigerant evaporates rapidly and absorbs the heat of the surrounding water, causing the water temperature to drop and gradually freeze into ice.
[0007] The gaseous refrigerant after evaporation is sucked into the compressor for the next cycle.
[0008] Therefore, the efficiency of the refrigerant cycle determines the refrigeration efficiency of the tube ice machine.
[0009] In view of the above defects, the present design person actively researches and innovates to create a full-liquid tube ice evaporator, which has more industrial use value. INVENTION CONTENTS

[0012] This full-liquid tube ice evaporator circulates the refrigerant in the annular closed space through the liquid inlet pipe and the liquid outlet pipe, and the refrigerant wraps the ice-making pipe in the annular closed space to complete heat exchange and ice making operation.
[0013] Further, there is a partition plate in the annular closed space, the partition plate is in contact with each inner wall of the annular closed space, and the partition plate is used to separate the liquid inlet pipe and the liquid outlet pipe.
[0014] The inlet pipe and the outlet pipe are separated by the partition plate in the annular closed space to form a flowing channel, thereby facilitating the circulation of the refrigerant.
[0015] Further, the annular closed space is arranged in sequence clockwise from the partition plate, the lower plate and the upper plate, and the lower plate and the upper plate are located between two adjacent ice-making pipes.
[0016] The annular closed space has a plurality of lower plates and upper plates arranged in an upper-lower staggered manner, and the upper plates and the lower plates are located between the ice-making pipes to provide flow guidance for the refrigerant.
[0017] Further, the lower plate is in sealed contact with the outer ring, the inner ring and the lower cover, and the lower plate has a gap with the upper cover.
[0018] The lower plate is in contact with the outer ring, the inner ring and the lower cover, and the gap between the upper end of the lower plate and the upper cover is used for the overflow of the refrigerant.
[0019] Further, the upper plate is in sealed contact with the upper cover, the outer ring and the inner ring, and the upper plate has a gap with the lower cover.
[0020] The upper plate is in contact with the upper cover, the outer ring and the inner ring, and the gap between the lower end of the upper plate and the lower cover is used for the flow of the refrigerant.
[0021] Further, each lower plate and upper plate is located between two adjacent ice-making pipes.
[0022] Each ice-making pipe is separated by the staggered lower plate and upper plate to form an independent chamber, thereby facilitating the close contact of the refrigerant with the ice-making pipe and facilitating ice making.
[0023] By the above scheme, the full-liquid pipe ice evaporator has the following advantages: the refrigerant flows through the gap between the upper plate and the lower plate and the corresponding upper cover and lower cover to form a staggered flow mode, so that the refrigerant can perfectly wrap the ice-making pipe, improve the heat exchange efficiency, quickly complete the ice making operation, and make the ice block transparent and high in hardness and difficult to melt.
