Structure-improved ice-making evaporator

Abstract

The invention discloses a structure-improved ice-making evaporator, which belongs to the technical field of refrigerating devices. The ice-making evaporator comprises evaporating tubes, ice-making bars and a fixing tube, wherein a plurality of ice-making bars are fixed on a pipeline of the evaporating tube at certain intervals. The ice-making evaporator is characterized in that: two or more evaporating tubes are arranged in parallel, and are fixed on the fixing tube respectively. The structure-improved ice-making evaporator has the advantages that: the evaporating tubes which are arranged in parallel are adopted instead of a single evaporating tube in the prior art, and a reflowing pipeline is formed respectively by each evaporating tube, so that time consumed by a refrigerant flowing through the evaporating tubes is shortened, the evaporating temperature difference between the inlet and the outlet of each evaporating tube is reduced, the defects of slow ice making and slow ice removing existing in the conventional evaporator are overcome, the problem of non-uniform freezing at the front and back segments of the evaporating tubes is solved simultaneously, and the ice block quality and the ice-making amount of a whole ice-making machine are improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration devices, and in particular relates to an ice-making evaporator with improved structure. Background technique [0002] Ice machine is a kind of refrigeration mechanical equipment that generates ice after water is cooled by the refrigerant of the refrigeration system through the evaporator. It is widely used in industries such as aquatic products, food, supermarkets, catering, vegetable preservation and transportation, and marine fishing. With the development of the industry, the amount of ice cubes is increasing. The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed "liquid" passes through the evaporator to exchange heat with the outside air, and the "gas" absorbs heat to achieve the cooling effect. [0003] Due to structural design reasons, existing ice machines generally adopt an integrated single evaporating tube structure, an...

Problems solved by technology

In this technical solution, due to the long length of the single evaporating tube, there is a process for the refrigerant to flow through the evaporating tube, which makes the ice-making speed slower. Correspondingly, the de-icing process will also be slower, which greatly affects The efficiency and speed of the ice maker are improved; at the same time, the longer evaporator tube has a large difference in the evaporation temperature between the inlet and outlet, which makes the ice cubes produced by the front and rear sections of the evaporator tube different in size, which seriously affects the quality of ice cubes and production. amount of ice
