Abstract
The utility model discloses a kind of bromine cooling machine group copper evaporation tube, it includes inside pipe wall, pipe outer wall, internal tooth, outer wing, outer wing is a truncated rectangular pyramids shape, and truncated rectangular pyramids shape is single-screw with monomeric form and is looped around on the pipe outer wall, and the ratio that wing height and wing portion diapire are thick is 0.6-0.7: 1.The utility model heat transfer performance is good, and the efficient height is effective, can satisfy the requirement of evaporimeter high efficiency.
Description
Technical field
The utility model belongs to the heat-exchanging part in the mechanical engineering, is a kind of bromine cooling machine group copper evaporation tube specifically.
Background technology
Lithium bromide formula refrigeration machine is just towards high efficiency at present, and miniaturization and light-weighted direction develop, and also must update just and can satisfy the demand as the structure of the evaporation tube of refrigeration critical component in the lithium-bromide absorption-type refrigerating machine.The evaporation of a kind of copper was arranged in the past let it be that outer wing is a quadrangular, with monomer independently, closely be arranged on the outer wall of evaporation tube, though its heat transfer efficiency has raising, but because the ratio of wing type, wing height and wing portion bottom thickness does not all reach the most rational design, heat transfer efficiency is still lower, is difficult to reach the requirement to the evaporation tube high efficiency.
Summary of the invention
The utility model is intended to provide a kind of bromine cooling machine copper evaporation tube, and the ratio that its wing shape, wing height and wing portion diapire are thick is reasonable, and the heat transfer efficiency height is effective, can satisfy the requirement to the evaporimeter high efficiency.
Task of the present utility model is finished like this, a kind of bromine cooling machine group copper evaporation tube, it includes inside pipe wall, pipe outer wall, internal tooth, outer wing, it is characterized in that: outer wing is a truncated rectangular pyramids shape, truncated rectangular pyramids shape is single-screw with monomeric form and is looped around on the pipe outer wall, and the ratio that wing height and wing portion diapire are thick is 0.6-0.7: 1.The utility model heat transfer performance is good, and the efficient height is effective.Can satisfy the requirement of evaporimeter high efficiency.
Description of drawings
Fig. 1 is the utility model overall structure cutaway view; Fig. 2 is the utility model heat radiation wing enlarged diagram.
Among the figure: 1, outer wing; 2, pipe outer wall; 3, wing diapire.
The specific embodiment
Outer wing 1 of the present utility model is a truncated rectangular pyramids shape, and truncated rectangular pyramids shape, is looped around on the pipe outer wall 2 by single-screw rotation mode with monomeric form, and outer wing height is 0.6-0.7 with the ratio of wing lower bottom wall thickness: 1.
