Dry type tube ice evaporator

Abstract

The invention relates to the technical field of refrigeration equipment, in particular to a dry type tube ice evaporator, which comprises a barrel body. An upper pipe plate and a lower pipe plate arearranged at two ends of the barrel body; multiple heat exchange pipes in a vertical direction are uniformly distributed in the barrel body; two ends of the heat exchange pipes penetrate through and are connected onto the upper pipe plate and the lower pipe plate; a spoiler plate is arranged between each two adjacent heat exchange pipes and spirally rise around a middle axis; and two sides of eachspoiler plate are connected onto the side surfaces of each two adjacent heat exchange pipes. The dry type tube ice evaporator provided by the invention has the beneficial effects that the spoiler plates of the dry type tube ice evaporator provided by the invention have flow guiding and disturbing functions, a refrigerating fluid needs to circularly flow around the heat exchange pipes according toa set flowing direction, and the evaporation of the refrigerating fluid is accelerated, so that a heat exchange effect of the evaporator is improved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a dry tube ice evaporator. Background technique [0002] Ordinary flooded tube ice evaporators are mainly due to high equipment manufacturing costs, unstable heat transfer performance, and a part of the top that does not freeze, icing and deicing takes a long time, and the refrigerant charge is large. However, the existing dry-type evaporator also has the problems of uneven distribution of refrigerant and poor heat transfer effect. It is necessary to develop and design a dry-type tube ice evaporator that improves the heat transfer effect and reduces the amount of refrigerant charge. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dry tube ice evaporator with uniform refrigerant distribution, less charge and good heat exchange effect. [0004] In order to solve the above-mentioned technical problems,...
