The refrigerant vapor-liquid separator adopts a snake-shaped arrangement mode and comprises straight line sections and connecting sections, wherein a pipe orifice at the upper end is a refrigerant vapor inlet, a pipe orifice at the lower end is a refrigerant liquid outlet, and each straight line section inclines downwards, and the refrigerant vapor-liquid separator is characterized in that the downward inclination of the straight line section is gradually increased from top to bottom, and the numerical range of the inclination is 0.5-3.4%. The downward inclination of the straight line section of the condensing coil is gradually increased in an equivalent manner or gradually increased in an unequal manner from top to bottom, the cross section of the condensing coil is elliptical, and the long axis of the condensing coil is in the vertical direction of the straight line section. The utility model discloses can make the refrigerant condensate accelerate gradually to flow in cooling process, improve heat exchange efficiency, the rational utilization space.
Description
Technical field
The utility model belongs to technical field of refrigeration equipment, is specifically related to a kind of condenser coil that is used for evaporative condenser.
Background technology
Evaporative condenser is the high-power condensing unit that utilizes the evaporation of force air circulation and moisture that the refrigerant condenses torrid zone is walked, condenser coil is one of them important composition parts, and its effect is that the cold-producing medium gas of high temperature is condensed into refrigerant liquid through continuous cooling process.Widely used a kind of condenser coil adopts snakelike arrangement mode at present, comprises straightway and linkage section, the mouth of pipe of upper end is a cold-producing medium gas inlet, the mouth of pipe of lower end is refrigerant liquid outlet, and the downward gradient of each straightway is identical, and gradient is the arbitrary numerical value in 1%～3%.This snakelike condenser coil is in condensation process, and condensate liquid quantity increases from top to bottom gradually, and the cross section that the cold-producing medium gas occupies in condenser coil reduces from top to bottom gradually, thereby has influenced the heat exchange effect.
Summary of the invention
The purpose of this utility model is that the deficiency at above-mentioned prior art provides a kind of improved condenser coil, and it can make condensation of refrigerant liquid accelerate to flow in cooling procedure, thereby further improves heat exchange efficiency.
The purpose of this utility model is achieved in that
A kind of condenser coil that is used for evaporative condenser, adopt snakelike arrangement mode, comprise straightway and linkage section, the mouth of pipe of upper end is a cold-producing medium gas inlet, the mouth of pipe of lower end is the refrigerant liquid outlet, each straightway is downward-sloping, is characterized in that the downward gradient of straightway increases from top to bottom gradually, and the number range of gradient is between 0.5% to 3.4%.
The downward gradient of the straightway of described condenser coil equivalence from top to bottom increases gradually.
The downward gradient of the straightway of described condenser coil non-equivalence from top to bottom increases gradually.
The cross section of described condenser coil is oval, and major axis is in the vertical direction of straightway.
The beneficial effects of the utility model are:
1. if the pressure reduction of inside pipe wall resistance generation is ignored, pressure equated between then condenser coil was imported and exported, the cold-producing medium gas is isobaric condensation in condenser coil, condensate liquid can only rely on gravity to descend, condensate liquid increases gradually in condensation process, increases the gradient of condenser coil from top to bottom gradually, condensate liquid is refluxed accelerate gradually, reduce the space that condensate liquid occupies in condenser coil, improve the heat exchange efficiency of condenser coil.
2. under the prerequisite that does not increase condenser coil length and whole height, the top condenser coil adopts little gradient, and coil pipe is arranged tightr, saved the space, the bottom condenser coil adopts bigger gradient, though the coil pipe arrangement is loose relatively, but favourable condensate liquid refluxes, and has rationally utilized the space.
3. the oblate pipe of condenser coil employing forms with the pipe compacting, and processing and fabricating is convenient, and the major axis of condenser coil elliptic cross-section is in the vertical direction of straightway, and front face area is little, has reduced the resistance that gas flows through.
