Abstract
The utility model discloses a copper condenser tube for a Br refrigerating set, which comprises a tube inner wall, a tube outer wall, an inner tooth and an outer fin. The utility model is characterized in that the cross-section of the outer fin is a tapered shape; the whole body of the outer fin forms a band shape and is continuously coiled on the tube outer wall in a single screw type; the height of the fin compares with the thickness of the bottom wall of the fin of 2.5-3.5: 1. The utility model has the advantage of favorable performance of thermal transmission and is capable of satisfying requirements of high efficiency of a condenser.
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 condenser pipe 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 condenser pipe of refrigeration critical component in the lithium-bromide absorption-type refrigerating machine.A kind of copper condensation was arranged in the past let it be that outer wing is a cone, closely be arranged on the outer wall of condenser pipe, 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 condenser pipe high efficiency.
Summary of the invention
The utility model is intended to provide a kind of bromine cooling machine copper condenser pipe, 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 condenser high efficiency.
Task of the present utility model is finished like this, a kind of bromine cooling machine group copper condenser pipe, it includes inside pipe wall, pipe outer wall, internal tooth, outer wing, it is characterized in that: the cross section of outer wing is for conical, outer wing is whole to be looped around on the pipe outer wall for strip successively is the single-screw formula, and the ratio that wing height and wing portion diapire are thick is 2.5-3.5: 1.The utility model heat transfer performance is good, and the efficient height is effective.Can satisfy the requirement of condenser 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
The cross section of outer wing 1 of the present utility model is conical, and outer wing 1 integral body is strip, and on pipe outer wall 2, the ratio that wing height and wing diapire are thick is 2.5-3.5: 1 with single-screw winding continued circling for it.
