Abstract

A dripping small pipe is characterized in that a plurality of annular grooves or convex grooves or baffle plates are processed on the pipe wall, and small holes communicated with the inside of the pipe are drilled. The small holes are arranged in the grooves or the convex grooves, or the small holes are arranged on the pipe wall outside the grooves or the convex grooves or the blocking pieces; the grooves or flaps are annular, or incomplete annular, or spiral-shaped coiled on the tube. The invention effectively overcomes the surface tension among liquid drops, avoids the deviation of the liquid drops, ensures that the liquid drops uniformly and equidistantly drop, has wide coverage and high utilization rate of the evaporator and the absorber, and greatly improves the refrigeration efficiency of the air conditioner host.

Description

A kind of drenches tubule

Technical field:

The present invention relates to a kind of spray equipment, a kind of that is specifically related in evaporimeter and absorbers combination drenches tubule.

Background technology:

In evaporimeter and absorber in the absorption type air-conditioner host computer system, the copper pipe top all is equipped with to drip drenches tubule, be referred to as again the gravity type liquid distributor, according to the copper pipe Design of length of below evaporimeter and absorber, be drilled with a row or two row's apertures on a pouring tubule, flow out water as refrigerant, under drop on the evaporimeter copper pipe and the absorber copper pipe on, water as refrigerant evaporates rapidly, takes away heat, makes the rapid refrigeration of cooling water in copper pipe.Traditional drip that to drench a tubule be normal straight tube, the water as refrigerant that each aperture flows out is stained with mutually and is pulled due to the surperficial expansive force of water, drips from several points in the mode of concentrating, and drop is inhomogeneous, drips ground to counting far fewer than hole count.As: according to evaporimeter, absorber copper pipe length, it is 10 that the equidistant hole of drenching tubule is dripped in design, because the surface tension of water is stained with and is pulled, only have six points or seven points to drip, evaporimeter and absorber have 30% or 40% part there is no work owing to dripping without cryogen, that is to say, tubule is drenched in above-mentioned dripping makes the operating efficiency of evaporimeter and absorber reduce by 30% or 40%.Moreover a pouring tubule can not be installed abswolute level in evaporimeter and absorber, deviation is always arranged, this just might make dropping liquid trickle towards low side, cause a pouring Guan Yiduan to drip, other parts are not dripped, this greater part that makes evaporimeter and absorber copper pipe surface is not because of without working on the cryogen water droplet, and evaporimeter and absorber efficient are lower.

Summary of the invention:

Technical problem to be solved by this invention is: solve the problem that above-mentioned prior art exists, and provide a kind of and effectively overcome surface tension between drop, avoid the drop sideslip, guarantee that drop evenly equidistantly drips, coverage distance is long, evaporimeter and the absorber utilization rate is high, greatly improve dripping of cooling by evaporation efficient drenches tubule.

The technical solution used in the present invention is: this drenches tubule, is processed with groove or tongue or the catch of many annulars on tube wall; Be drilled with on tube wall and manage the interior aperture that is communicated with.

In technique scheme, the aperture arrangement on tube wall is in groove or tongue.

In technique scheme, on the tube wall of the aperture arrangement on tube wall outside groove or tongue or catch.

In technique scheme, groove or tongue or catch circularize.

In technique scheme, groove or tongue or catch are incomplete annular.

In technique scheme, groove or tongue or catch spirality dish are on pipe.

The present invention is owing to evenly equidistantly being processed with many annular diversion trench by designing requirement on a pouring tubule outer wall, be drilled with in guiding gutter and manage the interior aperture that is communicated with, the water as refrigerant that flows out in aperture flow to the bottom along separately guiding gutter and drips, each water droplet is by separately guiding gutter water conservancy diversion, do not interfere with each other, can not be stained with because of the surface tension of water and pull together, like this, have how many guiding gutters just to have the place of how much dripping downwards.As pressing designing requirement, according to evaporimeter and absorber length, a pouring tubule of top should evenly equidistantly be processed with 10 annular diversion trench, and be drilled with in guiding gutter and manage the interior aperture that is communicated with, dripping the pouring tubule just has 10 places evenly to drip, and evenly drip and drop on evaporimeter or absorber copper pipe in this 10 place, drip and evaporate, copper pipe is worked comprehensively, and utilization rate reaches 100%, and cooling by evaporation efficient greatly improves.and a traditional pouring tubule is only a normal straight tube, be drilled with aperture, as press evaporimeter and absorber length, design is drilled with 10 apertures, and the water that flows out in these 10 apertures is due to without guiding gutter, its surface tension is stained with these water droplets and is pulled together, concentrate and drip, like this, 10 apertures only have five, drip in six places, drop on the copper pipe of evaporimeter and absorber and carry out cooling by evaporation, to making evaporimeter and absorber only have 50～60% some works, utilization rate has reduced by 40～50%, utilization rate of equipment and installations is low, absorption type air-conditioner main frame efficient significantly reduces, energy consumption is still the same.A pouring tubule in traditional evaporimeter and absorber is installed and can not be accomplished abswolute level in addition, when having an end slightly low, the water that 10 apertures flow out will be to the low side sideslip, water droplet drips from low side, the middle part and high-end nothing drip, drip on evaporimeter, absorber copper pipe water more the concentration point still less, the copper pipe utilization rate is lower, lower to the efficient that makes evaporimeter and absorber cooling by evaporation, affect the efficient of absorption type air-conditioner main frame.Structure of the present invention looks very simple, but solved the large problem of evaporimeter, absorber efficient, the present invention relies on guiding gutter to overcome the water droplet surface tension to be stained with the problem of pulling together, also rely on guiding gutter to solve the problem of water droplet to the low side sideslip, the present invention has guaranteed droplet to drench tubule evenly, equidistantly drip, and the copper pipe of evaporimeter and absorber has been realized 100% work, and utilization rate is high, cooling by evaporation efficient greatly improves, and has also just greatly improved the efficient of absorption type air-conditioner main frame.And reduced dripping the requirement of pouring tubule installation level.Energy-saving efficiency and the technical performance of equipment greatly improve.
